Stepper motor bluetooth serial driver (Attiny85 & L293D)

Trandi blogged about his Stepper motor bluetooth serial driver project: How to put together a simple bluetooth driver for a nice little stepper motor (Mitsumi M35SP-11HPK) that I salvaged from an old Canon printer. It uses a small Attiny85 (the more I use them the more I love them ! :) ) programmed in Arduino, […]

Another project-a-week: ATtiny85 programming shield

This week Rwinscot shared his RickPAW ATtiny85 programming shield project in the forum: Saw a couple implementations of the ATtiny85 programmer on Instructables… and decided to roll my own. It’s bare-bones, but gets the job done. It works as a minimal Arduino shield and has headers for ‘jacking-in’ to the uC. Goals on this one are […]

RFID Multipass spoof using ATTiny85

Hudson from NYC Resistor was inspired by Beth’s avrfid.S project to try to build a replacement for the multiple HID Prox card he carried for work. Hudson notes that “Beth’s design is simultaneously a technical tour-de-force and an example of how badly we can abuse the Atmel chips.” The entire schematic consists of an ATTiny85 […]

Nomis: Simon game clone on ATTiny85

Christopher Woodall from HappyRobotLabs wrote in about his recent project, Nomis, a Simon clone made using an ATTiny85. It uses up 4 pins, 3 for LEDs and 1 for buttons (ADC input). The write up can be found here. Everything is completely open source (except for the EAGLE CAD limitations of course, which kind of […]
