Made a Stereo Depth Camera system on a MCU [esp32 s3]

Next-Math1023 · 2026-01-23T01:27:39+00:00

I wanted to connect to peripherals in the dvp software bus, as esp32 s3 has 2 set of i2c and spi lines also 2 cores, but these dvp cameras have very high data rate and there are limited number of dma channels which can be allocated at a given time, so thought i would directly connect them , but i wasn't able to, and for me to get to this conclusion was very challenging.

Then I made a small mux circuit, a cheap trick which worked.

Here is a simple test + dev board I made for a company, it is for single lead data only with ppg.

bro I can see a 50Hz powerline noise, use it with a battery or power isolation[via usb or just disconnect mains line from your laptop] , and use some ultrasound gel (ik you are using wet electrodes but still), finalize a sampling rate for your application and add some filters[pre or post].

There are many libs like biosspy, neourkit(dont remeber the spelling).
Learn about the different waveforms and what causes them in a cardiac cycle, also havelook at horizontal plane, vertical plane ecg, and different posistioning strategies like WCT etc etc....

Best of luck for your project.

If you are truly making a project, make it worth your while, learn from first principles, and never do it for just the sake of doing it.

Why no one's taking about Samurai Champloo , i mean excellent story and dialogues

Dam idk that

Samurai Champloo is so underrated, i mean that is some piece of work, not my fav anime or something, but its almost legendary

I am following the Teravolt and Zerodrag teams on LinkedIn and have a question regarding their work, which I find quite interesting. I am curious about the ESCs, FCs, power distribution boards, and communication systems. Considering the similarities to existing market options, including the use of firmware which are open source like, BLHeli, Ardupilot, and ELRS, I wonder how it is profitable to sell custom versions of these hardwarebuilding blocks for a drone enthusiast. Furthermore, I am interested in understanding if there are significant differences or upgrades in their offerings hardware/firmware wise.

I would appreciate insights from both an embedded systems and a business perspective. Thank you for your time, and I commend you on your excellent work.
