Topic: Advice on my 'Coaster' project (Read 544 times) previous topic - next topic


Here's a quick clip of the little 'roller coaster' I'm working on. Hope this is the right place to ask.
I could use some advice about a couple   things;  I'd like to use a bigger servo on the lifter, and I'd like to connect it to the lifter using levers and bellcranks,  pushrods etc. to give it more 'Rube Goldberg-ness', I'm still researching this on some Radio Control forums, but anything anybody  can add to the mix is appreciated.
I'd also like some opinions on a device/circuit  to trigger the servo when a ball lands in the lifter.  Photodiode?  Hall effect sensor? I'm open to all suggestions.
Eventually this coaster will be mounted  on a base with room for expansion and used to prototype new 'complications' (spiral tracks, loop-the-loops, trapezes etc) for other coasters.  Thanks all!


It looks as if you are using metal balls, so perhaps you could arrange a 5V wire that was shorted to the chassis via the ball?
