The SoC has a built-in hardware H264 encoder, you can write it all in Python, and it's much more capable in general. There is also an official Python library that handles all the camera and encoding stuff, called Picamera2.https://community.element14.com/challenges-projects/project14/spring-clean/f/forum/56828/so-i-guess-i-m-finishing-the-excavatorMon, 06 Apr 2026 10:50:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1faecd84-f73e-45ec-b6f6-5bacdadda6edLuckierBreadA while ago I started a project that I intended as a gift for my niece and nephew. The idea was to have an esp32 with a camera module host a web server and stream video. The phone or computer connected could then drive the rc excavator that I used as the project frame. I unfortunatly missed my deadline due to the complexity of high quality video streams. Turns out mjpeg doesn't cut it. That coupled with having to learn the esp-idf which was way harder than arduino really ran me up against a skill wall that I never got back on. But it's time to get back on that horse and try again.https://community.element14.com/challenges-projects/project14/spring-clean/f/forum/56829/bluetooth-caliperSun, 29 Mar 2026 23:37:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:91e2696f-1c5f-4f8f-8a5e-eb1139a28e89dougwThis is an addendum to my E-Caliper blog , because that blog has no option to edit.
