and hall thumb throttles

I went to the VA in the twin cities today and stopped at AXMAN, surplus everything store! ( I mean they have an old iron lung if you need one,all kinds of electronic parts and assemblies,laboratory glass ware,speakers,etc. and I found cheap Wuxing bike brake handles with the brake switch, like those on ebay for $19.00 +shipping. For 1.50 ea. that is $3 for a bike !! and hall thumb throttles about 1/4 turn with 3 leds $1.50 ea. ( i haven't had a chance to figure out the voltage they are set up at, yet but they all work! of coarse I got 6 brake and 4 throttles just to play with.
