USB Gameboy Cartridge Project


[Jose] thinks that the Little Sound DJ is too expensive and hard to find. Now he’s trying to build an inexpensive USB programmable GameBoy cartridge. Currently he’s working with a LPC2148 development board. It’s not quite clear where he’s going with this. He certainly wants to add USB programming, but it seems that he’s trying to hack a mp3 decoder in there as well. [update: yes, I know how to spell cartridge!]

Back From Belize Extra


Yesterday, I was standing on a tropical island off the coast of Belize. Vacation rocked with lots of SCUBA diving, spearfishing and snorkeling. I’m back home, shaking off the jet lag and clearing up my inbox. Thanks to [fabienne] for filling in and letting me unplug for a while!

[Darkrom] has set a new standard for Hack-A-Day readers… I haven’t seen it in person, but that looks like a legit Hack-A-Day tattoo.

[null] sent in a new use for a frequency generator, a spare car amp, a sub-woofer and a plastic coffee can – brass cartridge polishing.

[LoopyMind] sent in this Game Boy Advanced Movie Player IDE hack. It’s pretty much a direct CF to laptop drive cable with an external battery supply.

[Dingolishious] sent in a POE UPS/remote power control solution. Could be handy if you’re using many POE devices, or if you’re having power issues. He added an inexpensive remote power monitor/switch solution behind his UPS. It senses power outages and kicks out an email – and allows remote power cycling of his POE devices. Of course, if you’ve got a linux box behind the UPS, it can monitor the output from the UPS and send notifications.

[William] added a preamp stage to his iKEY usb recorder. looks like an interesting toy – it’ll record audio directly to a USB flash key. The pre-amp allows him to record in more challenging environments.

[Andrew] noted a simple mod to increase the deadly fire power of the ubiquitous airsoft pellet gun. It’s just a matter of reducing some extra space in the spring compression area.

Last but not least, [VIPER] modded his projector to use a 12v halogen headlight bulb. Not a bad idea – at one point I was pondering a 550 watt source four halogen as a possible replacement.

Wiimote Firefighting Robot


Chad brings us yet another use for the Wiimote: firefighting robot. The Wiimote acts as a communications gateway via bluetooth to a host PC. The IR sensor is used to detect the fire, and the commands from the host are passed along via the Wiimote expansion port. The robot is pretty basic, but the use of the Wiimote to relay bluetooth comms via I2C is a fantastic hack.

Wiimote Car Accelerometer


This one’s pretty simple, but anyone who’s ever spent time tweaking an engine will appreciate it. [Kevin]’s been using a wiimote to measure the acceleration of his car. He put together a script to dump the accelerometer output to a CSV file, then graphed it with Excel. He notes that the accelerometer output isn’t that precise, but it’s good enough to give you feedback on your mods.

DIY DS Lite RumblePak


This one’s been making the blog rounds, but it really fits us. Nintendo makes one, but this instructables tells you how to make your own for a DS lite. It uses a PIC 12F675 to read the input line and activate a vibration motor from an old nokia cell phone.

Oh, speaking of instructables, I forgot to mention that they finally picked a winner for their laser etching machine. Of course, if you lack the budget, you can make your own for $60.
