Arduino Shield Makes 8-Pin Chip Programming a Snap

Arduino Shield Makes 8-Pin Chip Programming a Snap

I was delighted to see the positive reaction to my latest video, Shrinkify Your Arduino Projects, which is based on a tutorial by MIT Media Lab’s High-Low Tech Group. Their tutorial walks you through the process of not only using the Arduino as a programmer for 8-pin ATtiny chips, but also how to use Arduino code and the Arduino IDE to program them. In order to make this process easier, Randy Sarafan created an Arduino shield for programming these diminutive chips. Head over to his Instructable to get the board and learn to build your own!

DIY soft-circuit RFID tags

DIY soft-circuit RFID tags

Here’s an older project by Micah Dowty, that I just found out about: a homebrew soft circuit RFID tag. Not content to just make a homebrew RFID reader using a Propeller microcontroller, he proceeded to design an RFID tag using only an ATtiny85 microcontroller and an inductor, and built an antenna for it using conductive thread.
