Rice University engineers repurposed deceased spiders as mechanical grippers [full paper: https://buff.ly/3zFjcLm]

Can my bubble help analyze this protocol?
All supposed "frames" look like this.
1ms high, 1.2ms low, then the "bits".
Single "bit" looks to be 644us, with 218us high for a 0 and double that (~436us) for a 1
Or maybe I'm misinterpreting this totally?
Any help welcome…

The HIMARS mobile rocket launcher has been in the news as a powerful new weapon in Ukraine. I thought a teardown of its internal electronics would be interesting. (Nobody would give me a HIMARS so this is a "virtual" teardown.) Laser gyros and other technology ahead... 1/57

A cheap way to make lenses:

So this is as close as I can get to detecting the pupil with my first attempts using SimpleBlobDetection. Any obvious suggestions how to improve the parameters (which seem pretty counter intuitive and poorly documented) ?

Say hello to Eric the example Eyeball. This should help developing a simple eye tracking implementation while we get the IR light source and camera position optimised!

An OV2640 wide angle long cable camera just arrived to try out, and (on the dummy head) it seems to be able to see both eyes when placed over the bridge of the nose. Has any eye tracking system every tried to use a single wide-angle camera before?

Some Sunday morning hacking. OpenCV is surprisingly wonderful. Already have basic circle detection working, now to try developing pupil detection in a more realistic scenario.

EyeSkills got stuck trying to get stereo cams to talk to android. Different approach : individual ESP32 EYE boards doing basic pupil tracking, providing API over WiFi. Is anybody interested in helping? I have zero experience with OpenCV and ESP32!
