Paid on delivery
Design an RPM/Speed sensor for a bicycle wheel & a voltage regulator circuit. The Voltage regulator circuit needs to be controlled by the measured RPM/Speed. i.e if 0 RPM, Voltage = 0 Volt if Maximum RPM, Voltage = 15volt Need help to do the Circuit or Already available reliable solutions which we can buy within a reasonable price. To get more idea about the circuit, I will explain the full experiment we are trying. See the video Link: [login to view URL] it’s a slot car race controlled with Cycle pedaling. The slot cars need a variable voltage between 0 to 15 volt to control the speed. In the video they might be using an actual dynamo or generator. To avoid the complexity we can avoid the generator part (or if that’s easy & cheap to use a generator we will go with that solution) Or we can use 15 volt adaptor with voltage regulator. The full Circuit, instructions and any code used is needed.

Best way is to go for COTS items for easy replacement and service. Standard Dynamo will give a friction effect while pedalling, however the RPM model will become a free pedal feeling at high speed. Contact for a free consultation. Thanks,Raj
