I’ve been trying to find an excuse to pick up one of the HD Aiptek cams for a while now. [windowlikker] posted his simple pre-amp + external audio input mod for his Aiptek AHD videocam. Unfortunately, the mod is limited to mono input unless there’s an un-used stereo input on the encoder board.

SDI Mod Your DVD Player
I’m not usually into products, but I like this one. Remember this diy SDI DVD video out mod which lets you send high quality digital video over coax? Thanks to Pixel Magic, you can mod a variety of DVD players to add SDI thanks to the kit they’re offering. At a glance, bt.656 and bt.601 appear pretty similar, but the eval kit from the original only claims to be compatible with bt.601 while the Pixel Magic version is for bt.656.
DIY Home Theater Preamplifier
[Dane] built this excellent home theater pre-amplifier. He used [Mark Hennesy]’s pre-amp design to start with, and added selectable XLR, RCA, SPDIF and even USB audio inputs. Discrete inputs from his DVD player provide surround input, and an analog matrix creates 7.1 surround from the 5.1 input. The design is very elegant, and even uses a VFD display that appears blue with some filters. I usually just buy my HT gear, but projects like this make me seriously consider re-building my entire HT from scratch.
DDR Pacman (AKA DDR Pad Rewiring)
[Jason] sent in his low-tech, but interesting hack to allow the use of a DDR pad with his Gameboy advance to play PacMan. He took a $15 DDR pad, gutted it and wired directly to each of the foil pads that he wanted to use as buttons. For his project, he simply wired each pad directly to the DPad buttons on his Gameboy. It’s really a pre-manufactured version of [fbz] zone switches that she built for her backpack strap wifi detector.
By the way, [matt] over at Instructables wanted me to let you guys know that they’re giving away a $15k Versalaser.
Super8 Automatic Film Scanner
[edocronian] sent in this interesting mindstorm hack. [Harri] had several Super8 reels that he shot during the 80s. His kids put together this mindstorm NXT transport mechanism, and he did the rest with linux. The lego’s pull the reel across an Epson scanner, and some linux hacks run the scanner, identify the frames, and reconstruct the film. Unfortunately, [Harri] didn’t release any of the software hacks he used to pull it off.
Day O’ Guitar Hero Mods (with A Bonus)
I’ve already gotten a pile of tips on Guitar Hero controllers today, so here we go. The first one is already making the rounds. [Mark] replaced strummer with a touchscreen LCD and a magnetic switch. [Mark]s ultimate goal is to add some optical sensing and make the guitar self playing. For details, hit the acidmods thread or just watch the proof of concept demo.
[Johan] sent in the second controller of the day, and it’s probably my favorite for guitar bling. The original mushy switches were replaced with micro-switches and CNC milled replacement buttons. Each button is individually lit with LEDs and a cold cathode lights up translucent panel in the body. A PIC controller controls the lights and provides some input options for button tapping. The video is actually pretty entertaining to watch.
For a little bonus, check out [Mastershake916]’s cast Hack-A-Day pendant.
NES Inside A Controller With Cartridge Compatibility
[Tony] sent in this Nintendo hack. It’s a fully functioning NES with Composite output inside an old school controller. On the back it’s got a cartridge connector, so you can play normal games, there’s a port for a second player/light gun, and for extra bling, the Nintendo logo is backlit. To pull it off, he stuffed a Super Joy III – A.K.A. famiclone inside the controller, did a marathon of soldering for the cartridge connector, and used the now unused controller wires to carry the video and second controller signals.
Yes, this has been around for a while, but I dig it.
