Fresh hacks every day
The T-1000 was the shape-shifting robot from T2 (the second Terminator movie). It was so amazing because it could assume the form and texture of anything; humans, piercing weapons, inanimate objects. This robot doesn't even compare, except for one small trait. When it needs a tool, it can build it as its own appendage. This really is nothing more than making tools with a 3D printer. However, the … [Read more...]
Drilling holes in PCBs is nearly always an exercise in compromise; the holes are small, precision is paramount, and the common solutions, such as a Dremel drill press, aren't of the highest quality. In a quest to find the best way to drill holes in PCBs, [reboots] even went so far as to get a pneumatic dental drill, but nothing short of a high-quality micro drill press would do. Not wanting to … [Read more...]
Earlier this week, fellow Hack a Day-er [Mike Nathan] reviewed Adafruit's new iPhone/iPad app Circuit Playground. The comments on [Mike]'s review turned to suggesting ElectroDroid as an alternative to Circuit Playground. Surprisingly, Hack a Day authors actually pay attention to the comments, so I've decided to throw my hat into the ring and offer up my review of ElectroDroid. For purposes of … [Read more...]
It’s not everyday that we review software around here, but the folks at Adafruit recently put together an iOS app that I figured might be of interest. Their iPad/iPhone compatible application is called “Circuit Playground”, and it includes all sorts of handy electronics reference tools. For the context of this review, it should be noted that I paid for the application myself, and that I have … [Read more...]
What do you do when you've got three broken function generators? Build your own, obviously. Since your workshop has already gone through three of these bad boys, you might find yourself repairing your build. Better not use any fancy ICs and go with a transistor only build. When [Miroslav] sent in his 'guerilla homebrew' square wave generator, we were really impressed. With a relatively simple … [Read more...]
[msuzuki777] is a self-proclaimed “Lazy Old Geek” with way too much free time on his hands. He recently picked up a laser cross and figured that he would use some of that time to make a laser tripod for various projects around the house. He pulled out an old camera tripod, and modified an unused CD jewel case so that it could be screwed onto the traditional camera mount. He added three bolts … [Read more...]
Students in the BASTLI lab at the Swiss Federal Institute of Technology Zurich had been stuck using underpowered and unreliable saws for quite some time. The saws often got stuck while cutting through PCBs and were generally a drag to use. When group member [Mario Mauerer] came across a big and powerful brushless motor in his basement, he decided it was time to upgrade the lab’s cutting … [Read more...]
