Fresh hacks every day
More old computers on FPGAs! [Andy] loves his Memotech MTX computer. It's an oldie with a Z80 running at 4MHz; the perfect target for an FPGA port. The ReMemotech has everything the old one has - cassette interface and all - and can run up to six times faster than the original. Also found in 10-forward If you're going to build a jukebox, why not go all out? Here's a touch screen jukeboxwith … [Read more...]
[Blair Kelly] has always been interesting in the concept of Remote Operated Vehicles. As soon as he got his hands on an Arduino he began his endeavor to turn an RC vehicle into a land-based ROV. What he's done so far is incredible. Here he's showing off features of the build using a PS3 controller. But it can also take commands from an Xbox 360 controller or an arcade-style steering wheel. We … [Read more...]
[DanNixon] has put together this unique interactive table concept. Usually, when we see the term interactive table, we think of an LED grid. That just happens to be what we see the most of. While this table does, in fact, have an LED grid in the table top, it also has several other features and some very nice construction. Instead of going the usual boring rectangular route, [DanNixon] decided … [Read more...]
[Thor] sent in an awesome motorized bike build he found coming from the fruitful workshop of [Jim Gallant]. It's an incredible piece of work built nearly entirely from scratch. [Jim] welded the frame together on a home-built jig that keeps all the chrome-moly tubes in alignment before they're pieced together. With the jig, the frame was kept extremely straight making a bike that turns very … [Read more...]
Here's one good thing about the bitter cold Midwestern winter, it helps keep you from overheating when working around a hot furnace. Back in February this iron pour happened in the parking lot of the Madison, Wisconsin based Sector67 Hackerspace. Look, they're making iron hearts! Now this isn't just a bunch of members who got together and decided to do some casting. As you can tell in the … [Read more...]
How we missed this one is anybody's guess, but one of the presentations at DEFCON last year covers a DIY radar build. [Michael Scarito] talks about the concepts behind radar, and then goes on to show that it's not too hard or expensive to build a setup of your own. We've embedded his 45 minute talk after the break. The two large pieces of hardware above should look familiar. They're descendents … [Read more...]
When [Josef Prusa] speaks at a conference extolling the virtues of 3D printing, he likes to give out printed objects to show off the possibilities home-brew fabrication. A favorite of [Prusa] are whistles - they're functional and show off exactly what a 3D printer can do. Printing out hundreds of whistles is a job for a factory and not a printer, so [Prusa] decided to customize each whistle with … [Read more...]
