He also made circuitjs, a very useful circuit simulator which I regularly use for prototyping. It lets you modify and probe elements in real time unlike spice simulators, so it is faster to modify a design in it.
I use spice simulators to check the final design since sometimes circuitjs can have instability issues in complex circuits involving stuff like the nonideal op amp.

- quaintdev 2mo agoI remeber using this when it was Java applet. Now he has converted everything to JavaScript for everyone to use. What a legend!
- gregw2 2mo agoHe also wrote zsh ( https://en.wikipedia.org/wiki/Z_shell https://en.wikipedia.org/wiki/Z_shell ) as a sophomore in 1990, moved onto other things a few years later, and a couple decades later in 2019 it became the MacOS's default shell.
- ipdashc 2mo agoThat's wild. I knew he was the circuitjs guy which is impressive on its own, and vaguely knew of the other simulations as well, but writing zsh as an undergrad... Wow
- eternityforest 2mo agoI use it rather often in professional projects, usually for figuring out power supply inrush transients, and I usually point anyone who wants to learn electronics to it. Just be sure you set the simulation step size appropriately if there's high frequency stuff happening, or the results will not make any sense.
