More on noise in current measurement (actually less noise)
I’ve increased the sampling frequency to 23kHz and got much more stable results, stable enough to be useful. The image here shows the current measured […]

ACS 713 / 723 current sensor experiment
In spite of some efforts, it’s still difficult to get a stable current measurement. As a reminder, on the prototype, the power is 25W with […]
back to Afro ESC (for 22V operations) + feedback frequency
The basic Afro ESC doesn’t support enough voltage for my needs (the solar panel can deliver as much as 22V). I tried the Spider ESC, […]
satellite modem – MCU communication problem solved
I started by replacing the modem with a trusty GPS, so I have a continuous flow of data with a checksum (GPS lines are checksumed) […]
