Quentin Santos ☛ The missing part of Espressif’s reset circuit
In the previous article, we peeked at the reset circuit of ESP-Prog with an oscilloscope, and reproduced it with basic components. We observed that it did not behave quite as expected. In this article, we’ll look into the missing pieces.

Arduino ☛ This automatic emergency braking system protects RC cars
The Arduino constantly monitors the ultrasonic sensors. Under normal circumstances, they won’t report seeing anything — or at least not anything close by. But if something like a wall is nearby, the Arduino will immediately go into action and send a braking command (via a PWM signal) to the RC receiver. That’s a Flysky FS-i6X in this case, but the process should work with most others.

Robotic Systems LLC ☛ Moteus performance analysis tool
Recently I showed I was able to use the new dynamometer fixture I built to capture detailed thermal modeling parameters for motor controllers and motors. In this post, I’ll describe how I turned that into the initial version of a tool that lets you compare the performance of different moteus controllers (and some others), along with different motors, to help design an overall motion system.
