Home built CD changer contraption
Great Maker project for CD burning automation – “Building some sort of gadget that changes the CDs in my cd tray is something I have often thought about. Mostly in the context of ripping my CD collection or burning a backup of my 5 gig photo collection. My first thought was to come up with something extremely simple, with no electronics. Ideally, the motion of the cd tray would trip some sort of mechanism that would eject the CD from the tray and insert the next one. After months of thinking, I still hadn’t thought of a mechanism that had a hope of actually working.” Link.
And we’re back! PSPupdates is cranking out the PSP goodness! – “That’s right, the day we’ve all been waiting for has finally arrived! Thanks to the fantastic work by our forum moderator Fanjita and his coding companion Ditlew, it is now possible to play vast amounts of homebrew programs and emulators on every PSP in the world, including those with 2.60 Firmware! Thanks to their monumental achievement, every PSP in the world is capable of playing homebrew!” [
Ian’s new Instructable looks great for Nixie tube hackers, but be careful this one requires a lot of care. He writes “This SMPS boosts low voltage (5-20 volts) to the high voltage needed to drive nixie tubes (170-200 volts). Be warned: even though this small circuit can be operated on batteries/low voltage wall-worts, the output is more than enough to kill you!” 
Check out Steve’s amazing paint ball shooting, RC controlled tank made from printer parts. There are dozens of photos on how he made it and best of all Steve talks about the different parts, problems that needed to be solved and documents some clever solutions to power, move and use compressed air for the paint balls.[
Ryan writes in with an awesome Xbox hack! “An Xbox headtracker system – Built for around $6.00. I interfaced directly to a xbox controller pcb with photo resistors. Using some cardboard and tape and a led head mounted flashlight and some wire i made a useable headtracking system that is based on using the right thumbstick as an interface as it is usually for camera control in third person games, or direction in first person shooters.” 
DIY live has some good tips on fixing that old NES “I took apart my nintendo, and found the 72 pin connector. I took my smallest flat head screw-driver and pried every pin up a little. Over time, they had lost their springiness (I don’t know if that is a word, but it describes what I am talking about). This is a pretty good fix. It may not be the best, but it works. Another thing to help out is to clean the pins of your old cartridge. You can take a wooden pencil with the red eraser, and rub it on the pins of the cartridge. Make sure you get all of the eraser off of the cartridge.” Thanks Star!
