Fresh hacks every day
Being able to see what you’re doing can be the hardest part of drilling the through holes in those freshly etched printed circuit boards. We don’t know why we didn’t come up with this, but [Markus Gebhard] solved his shadowy woes with his 20-LED Dremel light ring. Honestly, how many times have we seen lights rings in photography without … Read the rest
These speakers play different audio tracks depending on which orange square the sit atop. They’re RFID aware and the orange tiles are tags. If you get tired of a track just move the speaker to a different one, or place the speakers next to each other to play the same song. We’re sure there’s a project for us here, it’s … Read the rest

We’ve seen levitating magnets before, but this is particularly stable. He says he is using lasers and a control system of some kind to stabilize it. Just to guess, we’d say that the … Read the rest
[Jeri Ellsworth] stopped by Pearl Biotech’s booth at Maker Faire and took a look at their open source DNA sequencing work. It is by no means a grab-and-go solution for anyone, but from what we’ve seen in the video they’re breaking down those laboratory walls and letting us in to dabble at this work (assuming you’ve got a few … Read the rest
[Jos Weyers] tipping us off about this lock impressioning video. It shows his final round of the lock impressioning championship at this year’s SSDev conference. Even though he shaved about fifteen seconds off of his 87-second single-lock record from last year he came in third overall because the competition averages times over several rounds.
