Fresh hacks every day
[dgcx] has been working on reimplementing a PDP-10/x on an FPGA for the last 2 and a half years. This surprised us because we're only hearing about this project now. After designing three versions, [dgcx] eventually ended up with a one-FPGA implementation of a PDP-10 and an awesome PDF writeup. Although PDP-10 emulators do exist, this project isn't an emulation - the system actually has the … [Read more...]
[Florin] picked up a cheap multimeter in order to make multiple measurements at one time. Unfortunately, he wasn't very good at remembering to turn it off when he was finished so he burned through some batteries. Why an auto-off feature wasn't the first thing coded into the firmware we'll never know, but [Florin] developed his own hardware-based auto-off circuit. It sounds like he had all of the … [Read more...]
After seeing our communications via light post , reader [Chris] dropped this handy little link in our inbox. A very good tutorial about using infrared to enable communications between 2 pic micro controllers. The tutorial covers all the parts you will need, physical wiring and schematics with notes detailing each section of the circuit. It then goes on into basic IR theory, and a simplified … [Read more...]
[Maayan Migdal] wrote in to share a really cool drum kit he constructed that has one special twist - no drums at all. Using a simple MIDI device and an Arduino, his “Air Drums” look pretty sweet. The hack makes use of a pair of garden rakes, which serve as his drum sticks. The rakes were cut down and modified to allow the addition of accelerometers and some USB cables. The left stick … [Read more...]
Console hacker [techknott] has a skill set that is quite possibly second to none. We do love [Ben Heck] and think that his portable consoles are beyond awesome, but you’ve got to check out this portable GameCube [techknott] put together. While the construction details are pretty sparse, the video below shows off the bulk of the portable ‘Cube’s best features. Far smaller than his Flip-Top … [Read more...]
Not satisfied with the traditional daily pill boxes, [Ryan] set out to build his own. According to his article, these particular pills had to be taken every three days, and he wanted a solution that required "zero effort." Although one might question whether his solution actually took this amount of effort, the build came out very well. The result is a box that reminds one to take a pill from … [Read more...]
[Ben Leperchey] is working on building a Sega Master System clone using the Papilio One FPGA board, and although his ultimate goal has yet to be reached, he’s bringing some great stuff to the table in the meantime. One component that is necessary for any sort of game system clone is NTSC/PAL video output, naturally. Since no one had constructed a TV output “Wing” (The Papilio One’s … [Read more...]
