Temperature Sensors, New Instructable
Dave Hrynkiw
February 5, 2010
Woo, we've had a busy week! To start things off, we have a new category - Temperature Sensors! So far it has the following items:
- Humidity/Temperature Sensor
- DS1620+ Serial Digital Thermometer
- DS18B20+ Temperature Sensor
- Devantech TPA81 8x1 Thermopile
- LilyPad Temperature Sensor
Yeah, it's a pretty bare category at the moment, but we'll be adding to it over the next few weeks.
The other piece of news we have for you is that we've just completed and posted a new Instructable! This one is for a Solar-Powered Battle Symet - yeah, it's like the other symet, except it's turned up to eleven. This guy will go absolutely nuts once it's discharged its power, spinning like crazy. Get two or more of them together and watch 'em duke it out! Hey, look, we even made a movie for it! Oh, and here's a parts bundle - it's just like the other instructable (the Wannabe Miniball).
And that wraps things up - have a good weekend everyone!
