RCA dvd player died

So like. My kid loves his dvd player. I got it for long car rides. It was one of the dual screen video players with a dvd player one side and just a screen on the other. Well one day it got broke (the dvd player side). 8 kids one room, you know the rest.

Enter raspberry pi powered openelec thing. Goal make it live. And keep all stock functions and controls on the screen (all work)
Bottom left Usb car charger soldered in to pOwer the pi. Cause i was lazy and ya no circuit built today. All off the shelf

Yep screen workd
Shoe horned in
Yes I know the dremel got away from me. :D its for my kid, he doesn't care.
Had too insulate the board with hot glue The connector on the middle right is for screen controls. Which when ground control the brightness etc. (found this out the fun way).

And as you can see below I was super lazy and got out my butane power soldering iron, and not my electric one. 

It works and he likes it. No modification of the pi needed, cost 0, had everything on hand. Controlled over the phone via the xmbc remote app

Sometimes being lazy pays off. Cause I was totally too lazy to toss out the dvd system after it was broken, and then tripped on it with the pi in my hand. 45 minutes later its what you got.

Some what specs.

RCA out from the pi to the Screen soldered on the screen side RCA jack on the PI Side
Dual stereo via old head phonejack soldered straight to the board.
Running openelec 3.2.4(newest as of today 7 mar 14)

Configured the Pi on the tv then installed it in the RCA screen,
Dremeled (badly) access to usb.

Powered via car adapter hacked up with wire cutters (seriously way easier than going out in the cold for parts)

Still to do. Adhoc interface stuff for on the road or I could just name my phone's wifi access point to the same thing and control it like that. 

And yes I know this format hurts the eyes. I totally dont update enough. etc. I am in the 82nd Airborne give me a break and yea that. Only wrote this up because there is still lot of room in the case and you can use the gpio of the pi to create a totally cool remote control for a robot with this. I will be on the look out for another one of these also. See my ISO of add on craigslist :D

Edit: quick shot of pass through. Audio and video work.

Just learned a ton, managed to spend about 5-6 hours to solve the issues with Tape's help aka hints and his awesome post.

Not bad for not even hearing of Steganography before yesterday.

On his page is a photo that he said has a embedded rar file. It does. But it is only part of the game.

Is a hint to more of the story. I wasted a few hours on it. Very fun to do forensics on. The photos and text are clues. Have fun and Thanks Tape for writing that post I stumbled on

Setting up the laptop

Well since I change linux flavors like underwear (almost daily). I decided to redo my partition tables yet again.

Going to allocate 15 gig's of space for iso images. After downloading them I can toss them in the space, do a quick grub edit and update and bam! Libe file system without needing a usb drive or burning cd's

Puppy bot

Build a robot for acadian to get him started in robotics.

Everything in it, is stuff I had laying around.

The button on top triggers, 4 rgb leds inside of it. Its powered by a jeenode, Yes those are bobbers on the rear antenna. The wheels are two cd's with some 1/8? bearings hot glued between them and wrapped in plastic wire wrap conduit.

I did a quick continous rotation mode to a pair of servos. The front "wheel" is a ping pong ball mounted to a pair of springs.

Over all it tools around good. With a 9v battery as the power source. The sonar just lets it back up a little bit and turn left or right off a random guess.

i found an old cell phone i might use the battery out of that to power. I will upload some more photos of the build when acadian goes to bed

Open Source Robot

Thought I put this up: Guess not

They are the start of my open source project

On an Airplane

Took a bit of a trip this week, which I totally did not want to make, after a few stressful days I am glad to be done. I am writing this on the plane ride home so it will be short I guess.

I got a chance till my battery ran out to work on my racing simulator code. I added in a calibration routine for it and stream-lined the button setup and initialization routine. This should make it respond faster than I can see or tell. Aka reduced the lag a bit.

Next I have to build the output to the u8 and make sure it (linux) works fine with the computer.

I have 4 user buttons, start, select and Will be adding a button to calibrate the steering for the chip only.

If I ever get time I will be making the pedals and the shifter and adding them into it.

Mentally I am drained after a very very long week. So I am slightly glad my laptop battery was not fully charged.

Talk at you internet people later - john

Ps I am still thinking delta bot 3d printer fyi.
