Turn a $3 AVR programmer into an ATiny

Posted on April 1, 2016 by robertwilkie

Basically the $3 AVR programmers are atiny’s that you could reprogram yourself.  Cheaper than buying an arduino itself. Dirt-Cheap USB Arduino Hack From the Past

OpenGarage…interesting, but how secure?

Posted on March 18, 2016 by robertwilkie

Interesting project.  But…not so sure how secure it is.  Its using Blynk for the Phone App. http://rayshobby.net/introducing-opengarage/

Using a $2 board to control speakers remotely

Posted on March 15, 2016 by robertwilkie

Well a knob anyways.  So this could be applied to other knobs.  It uses an ATiny (Digispark) http://www.instructables.com/id/Digispark-Volume-Control/

Simple vibration sensor

Posted on March 11, 2016 by robertwilkie

This is on my list to do.  A simple circuit where the “vibration will move the wired spring to touch the resistor.  Thus closing the circuit (triggering an event).  Pretty simple build and easier to do than using other sensors. … Continue reading →

Ha, make a simple door alarm

Posted on March 11, 2016 by robertwilkie

This project was a bit on the overkill, but still clever.   I think you could get away with an ATiny instead. http://www.instructables.com/id/Arduino-Theremin-Door-close-Reminder/

Hacking an EL Wire controller for an Arduino

Posted on March 4, 2016 by robertwilkie

Basically the author hacks the switch and power supply for an EL Wire controller so the arduino triggers it, and it uses the same power supply between the two.  Nice build.  I have a bunch of EL Wire from RadioShack … Continue reading →
