You don't need an integrated circuit to use electrical components to "detect" the coin. There are non-mechanical ways to recognize the coin has landed somewhere.ET2020 wrote:Any ideas for how to actually use the coin to activate another action? Last year I used a pressure sensor with an arduino, but since programmable components are banned this year, I'm not sure how to use the coin to accomplish anything.

Re: Coin Task
I just did a quick 30-second test, and copper foil tape, folded in on itself will hold its shape, but will easily deform due to the weight of the coin. You can just re-adjust after the run.

I would recommend looking at some of last year's devices. I would think some of them (like mine) used a pretty consistent method for the quarter that can be utilized without a microcontroller.

Re: Coin Task
Couldn’t you just have the coin land onto two pieces of wire, completing the circuit? Idk, thoughts on this?

Re: Coin Task
Aluminum foil. Its flat, conductive. Have the coin land on 2 strips which are then connected the wire. I've seen this done, and it seems to work consistentlyCookiePie1 wrote:Yes you can, but the real issue is whether you can use that task reliably.Shr3D wrote:Couldn’t you just have the coin land onto two pieces of wire, completing the circuit?

Re: Coin Task
We just wrap a small flat wood with bare wires of +, -, +, -, +, -. So no matter where the coin lands, it will connect the circuit. Never failed.C8H10N4O2! wrote:Aluminum foil. Its flat, conductive.

Pretty impressive. I'm sure we'll see a few imitations at Nationals.trdd wrote:Coin Task video with details and explanation.
