Fresh hacks every day
[Ari] and Jake from Noisebridge were out on the beach at Toorcamp when they saw some giant kelp and had an idea. Using a pocketknife, [Ari] cut a mouthpiece into the stem and cut the bulb in half. After some practice, they figured out how to play the kelp horn. [Jimmie], shown here, was able to get a pretty good range of notes out of it by playing it like a bugle. [Neil] tried to cut holes into … [Read more...]
The folks at Adafruit are busy as a bee working on bringing some of their really cool boards to the Raspberry Pi platform. Here's a few that came in over the last few days: 16 servos is almost too many Servos require a PWM output but the Raspi only has hardware support for PWM on a single GPIO pin; certainly not enough to build a gigantic, city-leveling robot. [Kevin] over at Adafruit put … [Read more...]
[Gert van Loo], the person who designed the alpha hardware for the Raspberry pi model B, has put out an expansion board for the Raspberry pi that we think many of you might be interested in seeing. Dubbed the Gertboard, this expands the Raspi with some GPIO goodness. We have seen TONS of tutorials for the Raspberry pi, and a few projects as well. We're hoping that we'll start seeing more … [Read more...]
Earlier this week, I showed you [Naim Busek's] kickstarter for his turn signal helmet. In that article I explained that, while the helmet is a neat idea, I was really interested in what [Naim] had told me about his power consumption. To put it the shortest way, he has made his arduino sleep so efficiently, it can be waiting for input longer than the battery's optimum shelf life. After that … [Read more...]
It does make us sad to see all the waste generated as we move from CRT monitors and televisions to flat panel offerings. Here's a way to cut down just a bit on how much is going to waste. [Denizpa] turned a CRT monitor into a planter. The project is very straight-forward. First remove the plastic body from the electronic guts. Next you'll want to choose your paint colors. While you're at the … [Read more...]
