Fresh hacks every day
[Andrew Jenner] pulled off something amazing with this Physical Tone Matrix. He wanted to build a physical version of a flash applet he had seen. Two layers make up the main user interface. The top layer is a sheet of acrylic that acts as a touch interface and below there's an LED matrix. [Andrew's] touch interface uses wires running throughout the acrylic as contacts which are polled via … [Read more...]
[Nirvous] managed to get composite video out working on the DIDJ. He knew that the CPU had the ability to generate the signal, and that similar devices already had this capability. After studying some DIDJ teardowns he figured out which connection on the processor should provide the appropriate signal. Next was the firmware side of things and after sifting through a lot of code he was pleased to … [Read more...]
Regular Hackaday reader [Osgeld] is at it again with this USB conversion for an NES controller. This is a ubiquitous hack that we started seeing very early on, sometimes involving an adapter kit, and other times including things like a thumb drive and USB hub. But this time around is truly a bare-bones version. He's using an Arduino but it's really just an AVR ATmega168 running the bootloader. … [Read more...]
[Matt Meerian] introduced us to his kludge of cardboard, tape, mirrors, and electronics in the form of a clever non lethal robin trap. Whenever a pesky robin would enter the box, a sensor is triggered, the solenoid drops a lid, and the bird is contained (and we assume taken far away after that). Of course the plan backfired; we wont spoil what happened, but you can click the link above to find … [Read more...]
[Dustyn Roberts] takes us through the process of designing gears for a specific application. Using Inkscape and Ponoko.com [Dustyn] takes us from equation to physical gear. While there is a plugin for Inkscape that allows you to basically drag and drop gears, this writeup will take you through the math to get exactly what you need. Those laser cut wooden gears are pretty cool looking too. … [Read more...]
