Mike's Xbox Repair

 

Not sure if this will work but I'm going to try.  The xbox

just lost all video.  Sounds work, lights work but just no

graphics which are kind of important to play it.  Here is

my attempt at fixing it anyway.

First time for everything!!

Well I did the fix and when I plugged it in it actually

worked fine.  I still did the overheat trick just for good

measure.  Here are pics of the newer style xbox.

Function Generator

 

This is an old project.  I built it in high school as my Electric

shop senior project or at least this was one of them.  I was 

given a schematic from which I had to design a pc board so

none of the wires crossed.  I then had to make a drawing

twice the size of the actual board which I used a drafting

board I had at home to do it with.  And since I was in

BW photography class my teacher helped me make a

positive film from my velum drawing.  I then etched the

board, installed the components and the thing actually

worked!  I then had to calibrate the waveform and here

is the result from all the work.

Biplane Repairs

 

Well it was going to happen sooner or later but I

guess sooner was the one for me.  After a gust of wind

slammed my plane into the ground I now have to repair

my biplane and here will be the updates.

Biplane Wing Strut Repairs

 

I started the cutout process for making the

wing supports out of plywood.

 

12-24-09

 

Wing Struts

 

I cut out plywood doublers to support

the bottom wing strut mounts and

all I got to do is make up some epoxy

and start gluing stuff.

Biplane Wing Strut Repairs

 

I got the wing struts cut out, sanded and

built up.  All I need to do now is taper the

balsa and cover them and that will be one 

repair out of the way.

Xbox 360 HDD 250gb upgrade

 

I upgraded my programs hard drive and had a spare

250gb drive available to see if I could upgrade my old

20gb xbox drive to a new 250gb size like my new CoD

xbox unit that came with a 250gb drive.  After lots of

work I got it to work, installed a game on it and it 

actually played.  So now my old xbox is able to have

a 250gb drive like my new xbox does!!!! yeah!!

 

HDD

 

I just can't get on xbox live using it...Sounds like Sony

has their head in the game.  They let you install new 

drives in their boxes without any problems so why not

Micro$oft?

Toshiba Laptop repair

 

I got yet another laptop for repair as the battery wont

charge or have the pc come on.  I checked the connection

and found the plug floating around like all the others but after

ripping the laptop apart I found that toshiba doesn't solder

the plug to the motherboard but instead they have a separate

wire and plug that mounts to the case.  I got a new respect

for Toshibas now.  So the MB wasn't the problem as I found

out so I checked the plug to find it was at fault.  It looked 

like the plug was unplugged a few times by pulling on the 

wire instead of grabbing the plug to unplug it.  I cut all the

plastic off the plug, cut back the wire where it was broke

and soldered the wires back on.  Now I got to figure out

a way to insulate it and strengthen it or the owner will

need to buy a new power supply or just a new plug if

they are available.

Biplane Repair

 

After flying this summer I was putting my plane together

to hang up and noticed the wing mount was loose so after

investigating it I found the fuse was cracked inside so here

is the reinforcement repair I did.

My Ultimate Biplane

 

Eleven years ago I started work on my biplane and had to

quit.  I then lost interest as I had several other planes at

the time and this year I decided to finish it so here are

some pics for you.

update:

6-28-09

 

I started my engine for the first time in 11 years after I bought

it.  It started right up and I ran it for 40 minutes to break it

in.  I got some finishing touches to do and off to the flying 

field I go.

 

update:

7-2-09

 

I balanced my plane by adding 8oz to the tail section.

I had to ditch the idea of smoke for now as the motor

interferes with the radio too much for me to feel

safe to fly it.

 

update:

7-09-09

 

My biplane had its maiden flight today with no major

problems.  At least it came down in one piece.  I did

have several problems.  The engine shook its screws

loose which have been replaced with socket head bolts.

The wing struts were missing 4 of the 8 bolts which now

has locktite and a locking nut on the back of them.  The

screw from the throttle servo fell out but the contol arm

stayed on thankfully.  And lastly the fuselage was broke

loose at two of the joints from the wings vibrating around.

I still need to glue them but it is still able to have another

flight.

My Nephew's buddy Xbox360 repair

 

Well I got my third xbox 360 repaired from the usual

red ring of death problem that haunts xbox 360 owners.

I did the usual xclamp replacement and reinstalled to

get it to work again and then over heated it to get the

connections to make again.

Metz P50 Battery Repair

 

I got a P50 battery for doing my brother's wedding

and use it about once a year and now my battery is

just flat out dead.  I went to a local hobby shop to get

a custom battery made for it.  It takes 8 Sub C cells.

In the middle of the pack is a thermal fuse and on either

side of the pack it has diodes in series which would be

used in reverse for temperature sensing.  I'll post pics

later as I took some before and will take some after it

is working again with the new 3000mAh batteries which

I hope wont mess with the charging or metering.  The

original battery pack is 1800mAh.

 

Original Battery

 

update:

3-10-09

 

I got the new pack, what a disappointment.  It had to be redone

the first time I seen it.  After I picked it up the second time the

diode in it was broke.  I tore it apart and marked down all the

parts that it needs.  8) Sub C batteries, 2) 1N4148 diodes, and

a 72 deg. C thermal fuse.  I got the batteries in the pack for

now to see if I can get the metering set right.  I'm discharging

the pack and then will recharge it again in hopes that the 

bigger cells will work out for me.  Pictures and info will 

be uploaded as time goes on.

 

Inside cover of Battery

 

update:

3-11-09

 

Well the overnight recharge test went well.  I discharged the

battery and recharged it with the onboard uP and I had a full

bar on the meter.  I then proceeded to finalize the battery repair

and put it back together to find it thinks my battery is dead 

again.  I guess when you disconnect the battery it defaults

to a dead battery.  So a recharge is back in progress and

the final test will be later this week when I shoot a few

basketball games and see how the battery does.

 

New battery pack

Discharge before recharge

Ok, last pic was kind of blurry

 

Schematic

 

Update: 

3-15-09

 

Wow, I took pictures for 5 1/2 hours with the new

batteries and still had 20%+  life.  I took 909 

pictures using 800 ISO and f5.6 in a well lit

gymnasium.  I'm pretty happy with my new found

pack.  Last year I took 670 pictures at the same 

place and the last 70 pictures I had to use AA

batteries as the pack went dead.  So the 3Ah

batteries made a good replacement for the P50.

 

Update:

7-26-09

 

If you get a dead battery pack after installing new

batteries ( which you probably will ), you need to

put the battery pack into an overnight discharge

recharge cycle.  Turn the pack on and then plug

in the power cord which should give you the 

discharge light.  My pack took 12 hours to go

through the cycle until I got a fully charged

battery where the indicator shows full charge.

 

If you have a new or old pack that seems to 

have a problem with "overheating" where all

the lights flash all the time and then it wont let 

you take anymore pictures you need to check or

change the internal diodes on the pack as that is

what I had a problem with.  I changed the bottom

left diode and the problem went away.

that wasn't working.  I replaced the diode bridge

and am waiting on parts for the quad buffer chip

to get it fully functional as the pump wont come

on without the chip.

I installed the new chip and presto it is as

good as new, or at least functional anyway.

I cut the old smt chip out with my knife

then desoldered the legs so I could solder

on the new chip.  I should have installed

diodes across the coils to reduce the chance

of destroying the chip again.

Snow Blower Repair

 

I sucked up a few bricks into my chute on the

out on one site so I had to fix it.  I can't drill

square holes so cutting off the bad and then

welding on a new piece of flatstock sounded 

like a better idea and here are the pics of the

repair.

It's working!! Somewhat, I only have the digital

board and the display board done and powered.

So now I can verify that my single sided bitmap 

version of Wayne's display board is working.

Here are some more pics of what I have.

 

update: 

8-8-08

Caution!  I hooked the up encoder to the wrong

plug so don't go off of my pictures for encoder.

Encoder should be under display board which

it is now so all future pictures after (8-8-08) 

will be correct!  I had hooked it up but never

tested to see if it works and of course it didn't in

its current location but I have it working now.

It is getting more exciting now the closer I get!

I now have the VFO board done and the coil

wired up temporarily.  I used jumpers to wire

it as I don't want any permanent connections

until I know what box it is going in.  The ones

I find that I like are $26 and I'm hoping to get

a cheaper one.  

 

VFO Hookup

 

update:

8-9-08

 

I now have a functioning VFO.  I had the

transistor in backwards as the silkscreen 

was for a different part # and my guess

was wrong(see above).  I looked them up and had to

turn them around.  I also missed the + jumper

for the transistor.  I got it all setup, wound

for the correct range and need to move on

to the next step.  Here are some pics of

my progress so far.

Bummer!

Ok, now I have all the boards done and

no audio output.  So I guess I got a bit

of troubleshooting to do.  I got a bit of

a signal on my O-scope but I will need

more work to find the problem.

 

update:

8-24-08

Got some help on voltages for different

pins and found a wrong size component

and replaced it and also calibrated the AGC

but now I'm hearing an oscillation in the speaker

so I may just have to add my shielded wires I was

avoiding until I got a box for the rig.  

 

update:

8-28-08

 

Well, I hooked up my rf gain again and my pulses

went away.  If I turn it down to open it the gain up 

I can still hear it but will work on that later.  I hooked

up a 2 meter antenna just to give it an antenna and

keyed up my Elecraft K2 radio and low and behold

I can hear CW!!!  I still want to get the pulsating out

before going much farther but it does seem to work. 

So maybe I'll hook up the amp and see if it'll tx to

my other radio.  Then it will be time for a box?  Not

sure where that will come from or if I build one from

scratch.

 

update:

9-4-08

 

IT WORKS!!!

Ok, I still got work to do on it but it does rx and now

even tx.  I used my fingers as a heat sink and shorted 

the PTT and tuned in my other rig until my fingers got

warm and unkeyed.  I did this until I was able to tune

into the cw.  I still have the pulsations when I turn up

the RF gain pot or down? however you want to look

at it.  Here are some pics or pic of my temporary hookups.

I still need to shield some of my wires and VFO which 

will probably end my osc. problem but no smoke test

has been finished.  Once I get working on it again

and change my wires and add a heatsink I need to

align it.

 

Final boards tested

 

update:

9-12-08

 

I think I found a case.  I'm using an old scsi case which

has a power supply built in so I cut copper clad board

to use as a face and will do the same for the top and 

back when needed.  It might not be permanent but it

is a home either way.  Here are some pics.

Halo 2 PC/Vista

 

I uploaded the 2 files I used for achievements

for h2vista which you load for the Halo 2 dedicated

server.  Even a silver account can host the file.  Just

start h2server load the custom playlists and wait for

2 other players to start the game.  Get through all of them

and you have a new achievement.  Then do the other one.

I couldn't fine one on the internet so I created it and I hope

someone gets some use out of it.

Simplex Repeater

 

I bought this thing from here.  I got 1 of 2 beta units

and of course I tore it apart to see what was in it.

Very clean project and so far works pretty good.

The cable I got with it didn't work with my radio

so I made an adaptor to try things out until I get

a cable made that works and looks nice.

K2PSU - RS Power Supply in an EC2 case

 

I'm going to use the Radio Shack 25 amp switching power

supply to put in the EC2 case to power my K2 and my K2PC

along with my Amp when I build it.  I am starting on making

my own custom volt meter and amp meter using a pic

16f877a or 16f877 to run everything.  I have the code done

to give me a top line and the bottom line will read the volts 

and amps and maybe have a serial port to customize it.

No luck on the current sensor giving me enough voltage

to drive my ADC.  I tried a current sensor from TI but it

didn't work.  I now ordered some free samples from

Maxim for a current amplifier so I'll try it when they

get here.

 

Update:

9-5-07

 

Good news, I got a current amplifier chip from Maxim

which is the Max4376.  The 5 pin chip just takes 2 pins

for the sense wires, plus voltage, ground and the 

output pin goes to the pic adc input.  I chose the 100x

multiplier to get 0-50Amps from only the 50mV input

for the current meter....Here is my test circuit.

Here is a laptop I fixed for a guy at work.  Well, sort of fixed.

The laptop didn't seem to want to charge the battery when

it was on without smocking some components.  Whatever

caused it to burn up in the first place was still bad, so I fixed

the MB so it could be used with the AC adaptor or battery

but didn't want to do both....New motherboard anyone?

Hacked my ppc6700 phone cradle

 

I had to hack my cradle to get the generic power cable

to power the phone and to charge it as just using the

usb port didn't seem to give it enough power when the

battery was low.  I found out that the power cable that

is supplied with the cradle normally has the negative

pin and the one right beside it shorted so the cradle

knows that it is plugged into power instead of usb.

It seems that the second negative pin turns on a 

transistor which powers the led to show power is

applied.   Works good now!

K2pc Computer in a K2 case

 

Here is a project I started to install a pc into an

Elecraft K2 EC2 radio case.  I got the idea from a link

I found on their website except I'm installing a DVD

drive into the case or maybe a burner.  Unfortunately

the MB was DOA right out of the box, so it went back

for replacement.  Project on hold until it makes it back.

update: 2-2-07

 

I got a new motherboard as the one from newegg.com came

DOA so I ordered one from logicsupply.com and not having 

much luck with the new one.  I can boot everything up as

long as I have a POST code reader installed in the pci slot

which makes no sense, but here are some pics of what it

looks like so far.  I have a 1.2 gig via cpu with 1gig of

ram and a 30 gig hard drive and even a cd drive which

will be a dvd drive (burner?) once everything is working.

I even have room to add a fan if needed but that defeats

the purpose of a fanless system.  I also have a wireless

network card to install yet.  And I might add a serial lcd

display to the front along with the leds and switches.

Ten-Tec QRP Radio Kit

 

This is a radio kit I'm doing for a friend.  I only have

the latest pic so far where I'm actually getting some

noise out of the unit.  I hooked the antenna up to my

other project which is an HF noise source where I 

etched my own pc board and it all worked pretty 

well so far.

After finishing the parts installation, I thought

I'd hook it up to some power and listen to a 

radio station or so.  I actually found one but

unfortunately it was the tail end of the QSO.

I haven't messed with it much after this other

than setting up the offset for tx and making 

a few adjustments.  Still need to work out 

the issue of no side tone which might be

the wrong part as the book called for 1 and

the actual one was another story.  Here

is a pic of the somewhat final radio with

all my test leads hooked up.

OOOOhhhhhh NNNOoooooo!!!

I learned a very hard lesson.....

don't talk on phone when setting up a radio!!!

I hooked up the radio backwards on my last 

test...heard a loud pop!  then I found a 

transistor with the head blown off of it.  

I think it fried the audio amp as it makes

strange noises now...I just figured I'd change

all the iffy components at a cost of about $3-5

plus shipping and tax I guess.  So I think I'm 

going to add a diode protection circuit to the

radio so it wont happen again....that and stay

off the phone while working on stuff!!

Elecraft K2 radio mods

 

This is where I started making my own pc boards

for mods for the radio.  I wanted to add a data port

and a cw tuning indicator circuit and couldn't find 

anyone who sold the boards so I made them myself

from the drawings I downloaded off the internet.  I will 

post the final pictures and board layouts when done.  I

had to redraw the mic extension/data port board as the

one I found showed 2 layers and the one layer version

drawing had the jumpers drawn on so I removed them

in order to make my boards.  I got all the stuff I needed

to make the boards and now I have more boards than

I know what to do with so if you need one, let me know

and we can work out the details on price then if interested.

 

These are the bmp's I used to etch my boards.

Please note that I put my call sign on these as

I had to convert them to bmp so I could print

them out and am in no way trying to take 

credit for the work.  I figured I did the work

to convert them and wanted my call sign in

my rig after completion so I modified them.

You are welcome to use what I have or get

them from the original authors but this is just

what I'm into and wanted to share incase 

someone wanted them also.

 

Please note that not all of these are to 1:1

scale.  If you see a 1x in the filename or 

see a 300 as in 300dpi then it is 1:1 and

can be printed as seen otherwise you may

need to do some scaling.  I plan on fixing

all the files here as I make them so keep

an eye out on the page.

Hard lesson to learn...I found that all my windings

were wrong on the board.  I counted the wires on the

outside of the core when you need to count the wires 

on the inside for the correct count.  I had to go through

and take 1 turn off of every coil including the T5 

transformer which was putting out 8.2 volts and would

not change with L30 which I found out it is to increase 

the voltage when going into the core.  So corrected

everything and was able to get the 6 volts needed 

on R30.

Pic 16F877A Embedded Ethernet

 

This project was written with MikroC to make a Pic 

16F877a work with an ISA card for embedded Ethernet.

I modified the original source to meet my needs for the

ip address of my network and found a circuit here that 

I modified to work with the EasyPic2 board and a few

minutes of soldering I now have a really cheap embedded

Ethernet to play with.  I robbed the ISA card from one of 

my old computer motherboards although I should have

used one from the board that went through the lightning

strike, but I got one basically for free, already had the

isa network card with the right chip onboard and paid

$5 for the circuit board from Radio Shack.  The chip

was one that came with the EasyPic2 board so the

cost for me was very cheap after the purchase of the

EasyPic2 board.  Of course you need the paid version

of MicroC to compile the hex file, but now the fun 

begins.  I have a few snapshots of my project also.

Logitech Xbox Controller Hack

 

This project was done to assist in my game playing.

I didn't like the fact that I had to let go of the controls

in order to jump or do a punch (A and B buttons)  while

playing the game. I like keeping my hands and thumbs

in one spot all the time when possible.  So I found the

traces on the circuit board to solder switches to and

paralleled mini switches to them under the controller

where my other fingers could get to without releasing

control of movement and aiming.  This isn't meant for

a tutorial on how to hack your controller, just shows

what I've done to mine to increase playing ease.

The pics are high enough res that you could use 

them to make your own mods if you want to but

don't blame me if you damage your controller.

I will warn that on the one side of the controller I 

was a bit off and had to carve away some plastic

in order to get the switch to clear the vibrator

motor frame so I could put it back together.

Either way, here is my hack and I'm pretty

happy with the outcome and look forward to 

playing more with the mods.  Check out some

pics of the mod while you are here.

Garage door indicator

 

This project uses a pic micro to control a set

of led's to show if my garage door is up or

down and even in between.  I use PORTA

for input using pins 0 & 1 for the door switches

and I use PORTB for the output of all the led's.

I haven't actually built the circuit yet so this is

only the preliminary part but it is here if you

want to give it a try.  I got the idea for this 

circuit from ELM ELECTRONICS.and the

program was written using MikroC

 which is a really cool compiler.  I liked all the

features it had to offer right off the bat with all

the classes setup to do lots of things the easy

way.  

update:

5-11-05

Well, I actually got the circuit installed and all

wired up and working.  The picture shows the 

switch I used that I got from Radio Shack and

the circuit board has 2 PB's on them to simulate

the door switches which was used for testing.

I also have an rs232 port which I decided not to

use and it is only partially hooked up and no

software was written for it either.

Insides of a Picturemate Ink Cartridge

 

Here is the insides of the Epson Picturemate 4x6 printer

ink cartridge.  There is a chip located on the bottom

that serves no purpose other than to lock the printer from

printing after 100 pictures have been printed even though

there is lots of ink left.  My black is about half full and the

other ones are at least 1/4 full.  I need to find a hack to fix

the chip problem so I can just keep printing until I run out

of ink and start getting bad pictures then install the new

cartridge and save even more money on printing my

own pictures.

Motion IR Commander

 

This project using the learning remote chip,

motion sensing chip and an AVR 2313 as

the brains to control everything.  I have it 

working pretty well.  I hook a camera up to

the back of the box, then hook the VCR

up to the other jack and add power.  Now

when the circuit senses motion, the cpu 

tells the IR remote chip to transmit the

signal to record.  After 25 seconds or

so it tells the vcr to stop unless there

was onther sense on motion and in that

case it gives it another 25 seconds before

telling the vcr to stop.  To test the circuit

I used channel up and down to see if it

worked and so far it works pretty good.

This way I can have motion sensing security

on my vcr without using up 6hrs of record 

time unless something is moving and I don't

have to hack my vcr and I can reprogram 

the box to turn my stereo on and off or 

control anything that uses IR to make it

work.

on the web.  I'm still waiting on my

driver chips to test it and to program

it, but will post code and pics later.

instead of ASM as I don't know asm at

all and I guess I have no interest in learning

it either.  I'll stick with C for now.

I got my chips to find I wired the columns

backwards from the way I thought they

should be so everything was backwards.

I had to read the display using a mirror.

I spent several hours figuring out how to

program this thing using PicC lite and was

able to successfully make a pacman, ghost,

smiley face and a colliding ball bounce to

start with.  I'll upload the code as soon

as I can and if that isn't soon enough send

me an email and ask for it and I'll either try

to get it posted or just email it back to you.

commands and then play any of them 

back.  I plan to use this for a surveillance

circuit to start recording on a vcr without 

rewiring the vcr.  I plan to use the video

chip to sense motion, use an AVR or Pic to 

control the learning remote and turn the

VCR on and start recording anytime there

is motion sensed.  I may just use it for an

alarm type circuit, but I'm in the playing

mode right now.  I bought the chip from

Dontronics if you are interested.  I bought

the IRL-10 Remote Control Learner IC

and the VMD-19 Video Motion Detector IC if

you care to check them out.

HeadBanger Amplifier

 

This is my version of the Headbanger headphone

amplifier I made for my Dell Digital DJ.  With the

ear buds, it works great, but outputing to other stuff

is a bit weak.  I built this pretty close to specs which

were very well written, but I didn't really follow the

directions except I took note of the ground separation

which I ran all my grounds to the battery ground and

the thing fired up the first time and works very well.

AVR binary clock (miniature)

 

I started making a miniature LED binary clock using

an AVR 8515.  I have pictures of the circuit but have 

no code available at this time.  It has been put on hold

for the moment.

2-24-04: I got the basic functionality working and able

to keep track of time although it is off.  I still need to

incorporate a free running 1second timer interupt to 

get the code acurate.  I'm using a 10mhz crystal right

now so keeping good time should be possible once I

get the timer working right.  Not much luck so far.

I can send the code if anyone is interested or if you

are willing to work on the timer as I don't have 

time right now for it.

I'm using 1 output per led and have 3 small buttons

for hold, slow and fast time set functions.

Update:

1-4-04

I coped out on this one so far.  I can't seem to get

the 1 second timer working on the 8515 so I 

opted to add the ELM440 freq chip to my clock

which has a 1 second output and a 60hz output

so I decided to use both.  I use the 1 sec output

for the time and the 60hz output is used to clock

the leds so they flash at 60hz when enabled.  I 

checked the current this way and with about 

13-15 leds on it draws around 50ma.  I guess

I could go with a slower flash rate or longer time

off to get a lower current rate but I plan to use a

small transformer to power it with so I wasn't 

concerned with power management.  I just wanted

to build this thing and see if I could get it to work.

Here is the latest code I have which works just

fine for my clock.

update:

1-15-05

I cheated and added an ELM 440 chip to give me

my 1 second pulse and also used the 60hz pulse to

turn the LED's on so they don't load the chip down

by turning on so many of them.  I checked the current

and it draws a max of ~51mA while running.  I installed

the working unit inside a red case, added a cap to the

reset circuit and a big capacitor for backup which runs

the clock for 30sec if power is lost.  I had fun with this

project and even though I couldn't get the timer to work

as planned, the clock works and is a nice addition to my

other clock.  Here is a new picture of the finished

clock also.

Directv DVR tivo hack

 

Ok, here is my info for my hacking experience

on upgrading my HDVR2 unit by Hughes.  I 

started out getting an HDVR2 unit with only

35 hours of record time for $217.  I set it up and 

played around with it a little to get the feel for 

it.  I then purchased a 200gig hard drive from

best buy for $229 before rebates and after 

searching the internet and researching this

I ended up using this link for the cd iso

image that I needed for the command to

copy one drive to the other.  I had 11.5gig

worth of stuff on my drive and it took

an hour and 4 minutes to make the copy.

I reinserted the drive back into the unit 

and now the system says I have around 120

hours of record time!  I did try to get a

unit from Circuit City already setup for 

105 hours of record time for $450 which

didn't work out, so I ended up doing it

myself, got more record time and after

rebates it will be a good bit cheaper

also.  

 

the command I used for the backup.....

mfsbackup -Tao -  /dev/hdc | mfsrestore -s 127 -xzpi - /dev/hdd

 

my 40gig original drive was the master disk in the second ide

cable and the 160gig was the slave to that drive.

 

I'm trying to get serial bash to work but haven't been

very successful with it.  Most things I found have been

tried and have failed, but I haven't given up just yet.

update:

1-11-04

I added another drive to my system.  I now have 243

hours of record time.  I started out with trouble 

getting any listings for my season pass manager, but

after a day it fixed itself and made me happy.

she has 120 hours of record time.  I also installed

a remote starter with keyless entry in her car but 

that is another story.

IRPD AVR 2313

 

This project uses a 2313-4 avr chip to control an IR

LED and a sharp ir receiver.  I have basic functions

working so far, but got a long way to go.  I only

have the source code available if someone wants

to get a jump start on coding their own circuit.  I

found that I had to add a capacitor from the output 

of the sharp receiver to ground to get a solid 

signal into the 2313 to work right or it would just

sit there and blink when placing an object infront

of the sensor.

Serial LCD Display

 

This project uses a 2313-10 avr chip to control a 16x2,

24x2,16x1,40x2 display depending on what is setup in

the source code prior to compiling.  The display only

has minimal functionality right now.  I used 8bit code

from one place and serial code from the SSC code I

used.  I only modified them to work together.  I have

functioning code to start at the top displaying the 

input from the serial port and when it is filled it goes

to the bottom line and then back to the top for now.

I made a serial LCD interface so I can use either a

14 pin or 16 pin inline lcd display or a 14 pin dip

connection.  I will upload the code and picture when I

can.

DTMF serial tone decoder

 

This project I'm working on will use an 8870 DTMF

tone decoder chip and a 2313 or 1200 to decode

the tones and send them to the serial line for 

viewing.  I only have the circuit for the 8870 chip

wired and no code yet, so this project may be a 

while.  But check back often for progress. 

 

Update:

3-25-03

 

I have some basic functionality working on this.

I have it decoding the tones properly and after

2 seconds of inactivity it adds a space and after

15 seconds it adds a new line.  I will be adding

more pictures and code once I have them.  But

for now I only have the code which is fairly well

documented.  Maybe even enough to get you 

started.  I only have a prototype setup now and

will be making a more permanent version

soon.  Then the fine tuning will start.  This

code is setup right now for the 2313 @ 4mhz

R/C servo onboard airplane camera control

 

status: done?

 

This project I'm working on will use a small r/c servo to 

control the shutter on a small digital camera to be 

installed onboard an r/c aircraft.  I plan on putting a 3

minute timer to delay the taking of pictures.   Then 

about every 15seconds or whatever seems to be the

best time to take all the pictures during a flight.  I don't

have any code to post or pictures to post, but the SSC 

used on this page would be a good candidate to start.

I plan on using the AVR 1200 on the final product to cut

down on cost.

 

update:

4-23-03

 

I got my circuit and prototype of the controller done.  I 

got a 50 second delay for the first 3 pictures and then

18sec delay until all pics are taken.  I can only take 13

pictures max without a memory card.  The avr 2313

chip takes the picture and then backs off the shutter

a little and then turns off the servo to conserve power.

The source code has all the data needed to know how

to hook  the circuit, if not, email me and I can tell you

how to wire it up or how it works if you need it. 

 

 

update:

5-21-03

 

I found that a 128mb SD card gave me about 450-475

pictures so I have it shutoff after 475 pictures.  That 

gives me a 3-4 second delay between pictures and a

28 minute flight to get the card full and most of my

flights only last about 15minutes before I run out

of fuel.  Pictures to follow after I get the new battery

installed and a clear day to go flying.

 

update:

6-8-03

 

I tested the camera on my airplane 6-1-03 and

it failed miserably.  The shutter button never

got touched.  Not sure why it didn't reach it

after all the testing I did, but it shouldn't do

it anymore after the program update I did.

I added a configuration function to the program

to allow field adjustment of the shutter control.

The arm of the servo cycles back and forth

moving towards the shutter each time until

the user presses the button to stop it and

the unit will be configured.  Then press the

same button to start taking pictures.  I hope

it will work next time.

 

update:

6-11-03

 

I added a windows program to test the

serial servo board.  Check it out under

my windows section of my programs.

NextStep clone with avr 2313

version 1.3

 

status: done?

 

This is a picture of my new robot controller.  I started with

code from a SSC from here.  I modified it to work as a 

NextStep  clone for my FirstBot  robot.  I have a basic

functioning robot using the new chip and whisker switches.

I'm working on getting the IRPD working next.

I will post the source code once I have it working with 

more pictures and schematics.  I'll try to keep my source

code well documented also.  I am using gcc and

avredit to compile my program and downloading it with

wppisp and my wppispgui located on my site.  

 

 

Update:

 

 

3-14-03:

I got the IRPD working.  It wasn't a timing issue.  I needed

to put a 10M ohm resistor between the LED pin and gnd 

to fix the problem.  My O-scope showed a bad waveform

and the resistor seemed to make things work great.  I

even worked on the whisker switch logic a bit so the

robot will backup a little before turning so it doesn't

turn into what it just bumped into.  The source code includes

the rom and all files created by the AvrEdit program.  I'm

using a delay_ms() routine for my timing.  I will upload

new pictures and schematic once created.  The source

code is pretty much all you need to get started on how 

things are hooked up.  

3-21-03:

v1.3 - I added code to keep the robot from getting stuck.

I found the 1.2 version would run toward a corner and if

angled right, it would just shack back and forth.  So I 

added some code to keep track of the number of 

cycles the motion is and if forward motion isn't  found

within 6 cycles, then it adds some time to the turning

of the robot to help get it out of the cycle.

SSC with avr 2313

 

status: done

 

This is a picture of my finished serial servo controller (ssc)

that I made with an AVR 2313 using code from here.  

  This rom is the one I used in my chip from the 

code I downloaded after I had to fix a few typos.  

You can download it here without the need

to compile the program.  You can use wppisp and my 

wppispgui to download it to the chip if you want.  I named

my file servo2 after modifying it.  The Modification which

is documented in the source code allows serial

commands to just read each general purpose IO

and return 0 if the pin is low and 1 if the pin is high.

All the other commands are there from the original source

code and works unmodified, so my rom is a replacement

for the original with some added features.  I compiled

the source with avredit.

I use pwm from 20 to 70 to get the servo to rotate 

90 degrees left and 90 degrees right without messing

up the servo by driving it too far.
