The combination of connecting a Raspberry Pi to COSM makes creating a internet of things much easier than it has been in the passed. The Pi with it's easy access to ethernet and COSM's drop dead simple usability will graph all sensor data you send to it. This tutorial explains how to connect a analog temperature sensor to the Pi and use a small python script to upload that data for storage and graphing on COSM.
Build your own ambient-light addition for a monitor or media PC television! By running the Processing code on your computer, the halo of LEDs will follow the screen colors to provide an awesome ambient light display that adds pop to TV shows, movies or games! Works using open source Processing and Arduino - so it'll run on Mac, Windows or Linux computers!
Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. Build the kit, and learn how to use it with these detailed instructions.
Make your projects to go green this summer with our specialized USB/Solar Lithium Ion Polymer Battery charger! This charger is a very unique design, perfect for outdoor projects, or DIY iPod chargers. We've spent over a year testing and tinkering with this charger to come up with a plug and play solution to charging batteries with the sun and we're really pleased with what we ended up with.
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 250mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!
