Throttle voltage/power curves, current noise/fluctuations, piezo buzzer …
↓↓↓ Complete description, time index and links below ↓↓↓
Last time we did some reverse engineering on a Haswing Protruar 2.0 trolling motor (link below). But you know how it is: The more you know the more questions you have. So we’ll dig a little deeper and even break out the oscilloscope.
First we fully characterize the throttle potentiometer and come up with a throttle voltage / power curve for the motor controller. Then we measure the current fluctuation on the 24V rail. Finally do some measurements around the buzzer.
00:00 Intro – the more you know the more questions you have
00:48 Reassembling – the tiller, respectively, throttle
04:28 Measuring I – throttle voltage/current and motor power
14:05 Measuring II – current fluctuations/noise on 24V rail
23:09 Measuring III – piezo buzzer voltage/current/frequency
28:23 Summary – what we’ve learned in this and the previous video
32:13 Wrap-up – next we design an electronic throttle control, bye
