HI, Can anyone recommend a way to make a motor with a low ROM - preferably 1-3? (I am building a lego linear accelerator, and they just don't spin as wheels). Cheers, Lotte

Hi guys, I want to have a tachometer to test my MOCs RPM and I am considering four options: Building it with LEGO (I have seen videos of LEGO tachometers (Nico71 is a great example) and they worked quite well but centrifugal tachometers are big and not really accurate, because you have to calibrate it yourself). Buying some sort of RC tachometer (I can't find any at a good price that could be attached to my MOCs. Buying the LEGO speed computer. Use gear ratio calculators and not buy or build anything (I will need to switch on the computer each time I want to know something, because I don't think there is any mobile app for Android to calculate LEGO gear ratios or at least I couldn't find it). What should I do? Any advice of which one to buy if you choose second option? Thank you in advance and sorry for my poor English, I hope you can understand it. EDIT: 5th option: Making it using Arduino but I think it's quite difficult/expensive to make it work as accurate as a "real" tachometer.
