Hello,
I have 2 24V lead acid batteries in parallel to make a power supply for my circuit. I want to do some drain tests, and plot a curve for % energy remaining vs. time. The load on the battery isn't that large, and I don't want to have to supervise my experiment for 12 hours solid.
Im...
Please excuse me if this comment is stupid, but would it not be possible to use a brushless DC motor - and then there wouldn't be an issue of a noisy output signal ?
The vehicle runs on pedal power, battery power and solar powar. It needs to be efficient as possible in terms of weight and performance as it will be racing. A support vehicle will be nearby throughout the race, analysing and recording performance data - so that race strategy can be changed...
Yeah silly mistake, I meant once every two seconds.
Im currently looking into using a frequency to voltage converter. If I know the voltage of each pulse, how easy is it to work out what components I would need to make a circuit such as this :

Hello all,
Im new to the site so please don't hurt me :blushing: !
My final goal is to measure linear speed of a pedal powered car, and send the speed wirelessly to my laptop which will record the speed profile.
My problem is that I can't find a sensor that will measure angular...
