Connect MPR121 to arudino i2c and power. On a Micro this is pins 2&3 plus VCC and GND. Flash the arduino and make sure everything works as you like. Breaking out the RST pin to a tactile switch is probably unnecessary, i've had no problem re-flashing...

Wire up your coil pairs in series and connect them so that all the south poles of the electromagnets face inwards. The resistor I used in the schematic is a 1k resistor. The purpose of this is to prevent the digital pin from "floating" high when in the...

Here's a functional program to initialize the hardware, read temps, and display temps as colors. Enhancements such as multiple sensors/LEDs per Trinket are possible but left as an exercise for the reader./* trinket_thermo ---------------------------------------------------------------------------------...

A small note for this step: I've tried around a few variants, so the wiring I show here is messy. If you want to repeat this step, maybe you think of a way to do it much better. But I'm using the DustBuster for 6 weeks in this configuration and I'm satisfied:-)....
I believe that the secret to creating truly meaningful human-computer interaction is to create some sort of emotional experience for the user. If we can make the user forget, even for just a few moments, that they are speaking with a computer—if we can...
