Fresh hacks every day
This year, students working for Texas Instruments as part of their Co-op program were challenged to construct a project around the company’s MSP430 microcontroller. A team of three students, [Max Thrun, Mark Labbato, Ian Cathey] decided to build something that would fit perfectly in any college student’s dorm room – an RGB LED coffee table.
[Phil] picked up an HD radio receiver when Radio Shack was clearing them out at a 60% discount. But to his disappointment, when he hooked it up the sound left a lot to be desired with limited mid-range and flat bass. After some forum mining he discovered that the optical output didn’t have this problem, and came to the conclusion … Read the rest
We’ve been working hard on this one and finally made a tiny bit of progress.
You will find that comments are now nested. We can see there are some slight visual issues, but we’re working on it. Please be patient with us.
Another edition you will find is the “report” button. If you find comments offensive, click that button to … Read the rest
[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 … Read the rest
[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.… Read the rest
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 … Read the rest
[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 … Read the rest
