This is a PCB made for the MQ-3, MQ-4, MQ-6 and MQ-7 gas sensors.
This is an LED-based “candle” that cycles through all the colors of the rainbow. The LectroCandle is a simple, through-hole kit, comprised mainly of 3 RGB LEDs and an ATtiny85 to control them.
This is the comprehensive guide to ZigBee wireless networks. This kit includes many of the parts and pieces you will need to work through the examples in the book. If you're serious about learning everything you need to know about XBee networks, this kit and the book will get you up to speed in no time (or as long as it takes you to get through the book).
This is a breakout board made for 20 pins SOIC style. This custom PCB will interface a standard SOIC package IC to 0.1" headers, which are easier to work with and integrate well with breadboards. There is DIP-standard 0.6" spacing between the two rows of pins.
This is a breakout board made for 28 pins SOIC style. These are custom PCB boards that interface standard SOIC devices to standard .1" headers. Standard .6" spacing between pins. Will fit directly into a standard width (600 mil) DIP socket. For wide ICs (memories, drivers, 74s, etc).
