His talks are always amazing. There are two others from the Hackaday Superconference which I absolutely loved:
* Tamagotchi singularity builds a botnet of tamagochi by emulating the original 6502 based hardware in an underground server farm * Project Details: http://spritesmods.com/?art=tamasingularity * Talk video: https://www.youtube.com/watch?v=3_-e_cJ1-Gs
* Tiniest Game Boy Keychain is a hardware tour-de-force... someone else on this thread said they weren't impressed by emulators in small packages. This one should prove you wrong * Project details: I couldn't find it on his site, here's the Hackaday article: https://hackaday.com/2016/11/28/tiniest-game-boy-hides-in-yo... * Talk video: https://www.youtube.com/watch?v=BYXAZZfJm-g
Those are both flashy, but I love his work on things like reverse engineering the controller for this hard drive and running his own code on it: * Project details: http://spritesmods.com/?art=hddhack * Talk video: http://bofh.nikhef.nl/events/OHM/video/d2-t1-13-20130801-230...
I always thought the ESP modules used weird Tensilica cores that were annoying to work with and lacking documentation, but I guess if you've already gone through the herculean effort of working all of that out, why switch to something like ARM?
He was subsequently hired to as a software engineering manager and technical marketing manager at Espressif, who were working on the ESP32 at the time.
I enjoyed Jeroen's recent appearance on the Amp Hour podcast where he talks about a lot of this: https://theamphour.com/359-an-interview-with-jeroen-domburg-...
See: Travis Goodspeed - A Keynote in Praise of Junk Hacking. It is a very enjoyable talk.
