I was asked if I could make a bigger version of an off-the-shelf gate wheel. One that would roll over uneven ground and some loose gravel a bit better. Pretty straight forward project with a little break to look like an idiot trying to make a non existent sensor work! If you have an Antra autodarkening helmet (Specifically Model AH6-260-0000) the batteries it uses are 2ea of the CR2032 coin cells.
