Fresh hacks every day
It looks like [rossum] and [Ladyada] have teamed up and been busy working on the microtouch. Since we covered it last year its had a few minor improvements like an upgrade to the ATmega32u4 microprocessor and some new software. The new and improved microtouch also features an accelerometer as well as some software to go along with it. Plus its now for sale on adafruit for about a quarter … [Read more...]
We're not sure whether to call this an Etch-a-Sketch upgrade or a computer interface downgrade but either way it's unique. [Martin Raynsford] added a familiar red frame to his computer monitor with classic white knobs that control horizontal and vertical cursor movement. There's even the click option by pressing the buttons in and, as you can see after the break, the modifications result in … [Read more...]
Cats do what they want, which rarely coincides with what their owner wants them to do. In [Dumitru]'s case, his girlfriend's cat [Pufu] tended to make it outside into the cold more often than desired. Rather than settle with the normal bell which gets obnoxious even when the cat isn't misbehaving, he decided to put together a custom Cat Finding collar. He used a PIC microcontroller as the brains, … [Read more...]
Don't just build a UAV, use it to blow things up. In this case a tri-copter seeks out colored balloons and pops them using low-grade fireworks. We've seen this type of flying armament before, but not in a 'copter form factor. It looks like the targeting and firing is done by an operator, and is not an automated system despite what the text overlays on the video after the break says. The lack of … [Read more...]
If you've been lusting after your own glowing display we're here to help by sharing some simple building techniques that will result in an interesting project like the one you see above. This is a super-accurate clock That uses ping-pong balls as diffusers for LEDs, but with a little know-how you can turn this into a full marquee display. Join me after break where I'll share the details of the … [Read more...]
What if there were only two steps for making your own printed circuit board; print, etch? That's what [Jeff Gough] has been working on and he presented the process in his talk at 27C3. In the first portion of the video after the break [Jeff] talks about various industrial PCB manufacturing processes in a depth you may not have heard before. We found it to be interesting but at about thirty minutes … [Read more...]
I [Caleb], finally had a chance to catch one of the live chat sessions over at Adafruit.com called "Ask an engineer". I was pleasantly surprised. Though the show is only an hour long, the amount of information covered was quite amazing. They started out, announcing a new, this really cool looking touch screen system, product and going over the tech specs. This very quickly turned into a question … [Read more...]
