Dan has a cool low cost Arduino based galvanostat/potentiostat, he writes – What? The Ardustat is my open source successor to Jonny Galvo. It uses a standard USB-Arduino unit with a custom designed daughterboard to provide: * A galvanostat with a current range from .1 µA to 10 mA * A potentiostat with a potential […]
Here’s a handy resistor value chart from our article Voltage, Current, and Resistance in MAKE volume 10….Voltage, current, and resistance are three staple quantities you’ll encounter with anything that has electrons running through it. Here’s how they all tie together- Link. Subscribers–read this article now in your digital edition – Link.
This one is for all the folks in the MAKE Flickr photo group, Flickr has a new upload screen, a lot better, with batch operations too! – Link.
This looks almost like having your own biosphere. Earthships are a pretty unique form of sustainable architecture that are compatible with a wide range of environments around the world. Each home is custom built to fit its particular environment, but there are a few things they all seem to have in common: They are built […]
Researchers at Tohoku University have developed a working prototype of what they are calling the world’s smallest gas turbine engine, a palm-sized motor they hope will one day be used to power autonomous robots and serve as a portable engine for personal transportation devices. “World’s smallest” gas turbine engine – Link
Jonathan Schwartz from Sun on the new GPL’d SPARC – We’re announcing the fastest microprocessor we’ve ever shipped this week – delivering 89.6 Ghz of parallel computing power on a single chip – running standard Java applications and open source OS’s. Simultaneously, we’ve said we’re entering the commodity marketplace, and opening the chip up to […]
Adam writes – RFIDIOt is an open source python library for exploring RFID devices. It’s called “RFIDIOt” for two reasons: I like puns. This one stands for “RFID IO tools” Since I haven’t done any serious programming for a long time, I felt like an idiot having to learn a whole new language and the […]
