"Metastability is a peculiar problem where a digital signal can take an unbounded amount of time to settle into a zero or a one. In other words, the circuit temporarily refuses to act digitally and shows its underlying analog nature."
"Since I used my RetroUSB AVS for the NES footage to get its higher-quality HDMI output, and the Panasonic FS-A1F (an MSX2 machine) for the MSX footage so as to get its higher-quality RGB output, I've technically just compared the PPU (Picture Processing Unit, the NES' graphics chip) and the TMS9918A without actually using a real PPU or a real TMS9918A. Good job, Nicole." lmao
"Our Goals: (1) Make integrated circuit prototyping as fast as 3D printing (2) Make DIY version of every nanofabrication tool (3) Get there with collaborative open source hardware"
good explanation! "Transfer resistor. Transistor."
thorough, accessible
"[G]iven that the cost to use a larger, better capacitor is effectively nil in most cases, you can keep experiencing that exact same level of cognitive load avoidance by just using 1uF or 2.2uF instead, in the smallest capacitor package that is practical for the voltage and assembly constraints you have, and placing it right up against the power pins. It’s free real estate, or something."
implementation of an MMU "from scratch" (i.e. a bunch of 74xx chips and some SRAM)
"a tool for converting vector artwork to KiCAD PCB files that lives in your browser"
detailed description with lots of links
"we should approach the public policy debate around this assuming that someday, we could be victims of exploding batteries, too"
with just a little bit of micropython code. neat!
"a digital circuit simulation platform... designed primarily for educational use... an open-source project with an active community"
"a driver board which talks to affordable E-Paper (or E-Ink) screens, which are usually sold as replacement screens for E-Book readers... This project uses Kindle replacement screens, which are available for 20$ (small) / 30$ (large) on ebay!"
