I've released v11.0 of my UCI Javascript chess engine Lozza with a (768->256)*2->1 SqrReLU NNUE eval. Essentially some bug fixes, a repo tidy and additional use examples.

Hector has become a bacteriophage now using 12 dof waveshare sc09 servos and bambu p2s printed body - he can gesturally say hi when tickled - detects the direction via the m5stack atom s3r imu and drops the relevant feet. almost ready to tackle walking.

wow, waveshare ddsm115 direct drive servo motor wheels are things of beauty. https://t.co/LEeA4b6Oq5

i've built some boxy robotic rovers to learn, so i asked chatgpt astra to be a bit more ambitious this time but use the 4 waveshare ddsm115 wheels + suspension units i have; now we're talking... :)

Hector hexapod can't walk yet, but he can jump! (wait for it after the sit...) even with one dodgy leg :)

Hi @waveshare00 , could you clarify the SC09 servo maximum continuous supply voltage? Your wiki says 4–6V, older docs say 4.8–8.4V, your 7.2V adapter lists SC09 compatibility, and mine have a factory 9V limit. Has the hardware or rating changed? Thanks! i.e. is a 2S LiPo safe? :)

Freddie is a little ESP32 based robot that chases (grandchildren in my case) via a tiny 8x8 thermal camera. https://t.co/t3n2cGHoT2

A simple little demographics/population simulation: starting age profile + fertility, life expectancy, working age, retirement age, net migration as distributions over N years => various graphs over N years. https://t.co/REXfJfEsqz
