Measuring hexacopter rotor speed with Logic Sniffer

Posted on Friday, January 20th, 2012 in hacks, Logic Sniffer, measurement by the machinegeek

Philip Peter has made a somewhat unconventional use of the Open Bench Logic Sniffer.

Recently we suspected that one motor of our hexacopter had been damaged in a crash. Since removing the motor requires almost the complete disassembly of the copter I started thinking of ways to test the motor in place.

In this article he describes a technique he used to measure the rotational speed of the blades of the hexacopter using a red laser as a sending unit and a photodiode and variable resistor connected to the Logic Sniffer adjusted to provide a 1 volt/2 volt dividing line between the photodiode’s dark and light states. He conducted the whole experiment using the stock OLS software jawi.
