Design and fabrication files for a temperature-controlled computer mouse.
The files
(made with KiCad in 2012) in this repository specify the design of a temperature-controlled
thermoelectric element, envisioned to be housed in a computer mouse. A
peltier cooler is used as the heating and cooling
device. Depending on the temperature, as detected by a
LM35DZ,
the direction of the voltage drop across the peltier cooler is reversed. This is
done by use of a
L293D
('H-bridge'). The PIC16F877A
microcontroller outputs either HIGH on one output and LOW on another
(or vice versa) and these outputs go into the inputs of the H-bridge.

Why make a 'temperature-controlled' mouse?
I used to play a lot of computer games, and was looking for whatever way to get an edge in my APM— I had the speculative theory that a heated mouse could improve the function of the mouse hand. Though the theory never panned out, I printed the PCB board and housed the creation in a prototype mouse shell— the thermoelectric element worked like magic!
