Agreed. How did you put together the wireless servo? I have been looking to get one for my helmet as well but I am not the best with electronics. How easy/difficult was it to make?
Well, erm...
I have a degree in Aerospace Engineering, and a lot of the stuff that I do can get a bit complicated.
However, if you are interested in getting to know electronics, I suggest looking at adafruit.com
There are a lot of tutorials on how circuits are made up and can inevitably aid you in making anything arduino based.
My specific circuit is arduino-based driven by two separate FLORA chipsets (one for the gauntlet and one for the helmet). Each chip has an RF transceiver connected that communicates through I2C comm (getting RF compatibility with I2C is extremely annoying).
Was it easy for me? Yes and No. Yes because electronic hardware is not too hard to understand, and once you establish/understand the principles of Ohm's and Kirchoff's Laws it gets real easy. No because programming I2C <-> RF leads to a lot of tiresome troubleshooting that eats time. But then again that is what engineering is all about.
Anyways here is a pic of the RF circuit used.
