Wireless foot pedal for my Tig welder

[Six_Shooter]

Six, I took a look at the Teensy, and it seems to be adequate for what I am looking at. Make sure I am correct here, I would need a Teensy to take the pedal's on/off (digital), and variable (analog) inputs, convert them to a digital signal, send it connected XBee, which would transmit the signal to the receiving XBee, then it would get passed on to another Teensy to get decoded, and tied into the foot pedal connector on the welder. Right?

So I would need two Teensys, two XBees, and two adapters for them? Seems reasonable.

Yep, that's how I would attack this.

Actually I would likely try to reduce the need for the Teensy down to just a uC, with the supporting power supply hardware. You can look up terms like "making your Arduino Project smaller" or similar to get ideas on how to do that. For initial development using a pair of dev boards and XBee modules will get proof of concept and prototype working.
