2 hours ago I got an email from Crowd Supply saying that my “Dabao Evaluation Board for Baochip-1x” order had shipped. Coincidence? Hmm…

wow it's transparent?

do UV and infrared photons not interfere with chip operations?

UV could have enough energy to change chemical bonds in the chip permanently?

Kirby64•12m ago

They absolutely would, UV mostly since it’s higher energy. It’s not stated but it’s possible they’ve coated the chip with a UV opaque coating that is transparent to infrared though.

I wonder if Defcon fucked over THIS YEAR'S badge creator (Bunnie Hwang) too, like Defcon did in 2024?

Fucking over Bunnie Hwang would be a stupid move on an epic scale considering how well known he is.
