Fresh hacks every day
Hackaday alum [Ian Lesnet] has been working in cahoots with a dedicated team of developers to produce the OpenBench Logic Sniffer. This caseless logic analyzer can operate at 100MHz and sample 32 channels at once. Better yet, a digital oscilloscope add-on is in the works. The pre-order comes in at $45, that's a lot of functionality for just a few greenbacks. We've embedded a demo video after the … [Read more...]
[Joe] tipped us off about his 112 LED coffee table. This 12-ups the LED matrix from Friday and 31-ups the Shiftbrite table. Driving this grid is an ATmega328 in i2c slave mode. It listens for display data from a second ATmega328 and uses that to set the array of TLC5940 driven LEDs appropriately. Separating the processing microcontroller from the display microcontroller allows for fast and smooth … [Read more...]
We always wondered what happens to ancient pianos when the internals can no longer be kept in a playable condition. [Jean Philippe Roch] gutted his elderly upright and fit a Korg Triton inside. After the break you can watch a few videos including a slide show of the work log. [Jean] separates the Korg keyboard from its case and places it in the empty upright piano rank. He then mounts the Korg's … [Read more...]
One of the worst moments almost every hacker has experienced is a hard drive inexplicably dieing. And of course, its at the most inopportune time and you've had no chance to backup! Recently there has been an influx of Seagate hard drives (specifically the 2700.11s) kicking the bucket with firmware errors 0LBA and BSY. The good news is [Gradius2] has made guides to unbrick your drive without … [Read more...]
[Anders] tipped us off about his hack that re-purposes a smoke alarm as a burglar alarm. Unfortunately, he came home in the middle of a burglary but wanted to be ready the next time someone tries to break in. By cleverly patching into the test button on an old smoke detector he created a circuit-trip alarm. One side of each piece of wire is secured to the frame and jam of a window. A paper clip … [Read more...]
Here's two input devices you can easily build with materials you already have on hand. To the left, [John] built a 3x3 keypad matrix from paper and tinfoil. The rows and columns are made up of strips of tin foil on the front and back layers of paper. The layers are separated by spongy double-stick tape. A 'keypress' results when the gap between the conductors is compressed with your … [Read more...]
When it comes to routers, there is one that is hacker's favorite, the WRT54GL. But a slightly lesser known company, Pirelli with their "Alice Gate2 plus Wi-Fi", seems to be a popular choice among our Italian friends. [Esteban] has done everything from installing serial and parallel ports, to unlocking firmware while installing Debian. Our personal favorite is the creative wiring of an … [Read more...]
