Good educational idea and polished presentation

This would be such a good game for introducing students to digital technology! This is so fun! We just had to draw them by hand back in the dark ages of the 2010s.
buildbot on HNThis is excellent, both educationally and from a UX standpoint! I've tried multiple times to read explanations on how transistors work and bounced off, but this time I think I've…
a022311 on HNThis is awesome! The truth table lightning round took me by surprise, I am rustier than I thought... One note: It isn't immediately obvious that the In/Out nodes can be connected…

Too hard with little guidance for beginners
From 3 comments
Ok you have put a lot of work in this and it looks impressive. But it needs a serious balance change. It is far too hard. Currently this may work as a brain teaser for people in…
hristov on HNI worked on deep sub-micron, full custom mixed-signal integrated circuits for more than a decade, and I can't pass the first level. > Wire an NMOS transistor so that when In is…

Timed truth tables and hex racer are too punishing
From 3 comments
The truth tables are way too hard for me. I need time to think and the 10 seconds is way too fast. If this is intended to be a teaching resource, avoid timers IMHO. It needlessly…
unsnap_biceps on HNA nice game, though the truth table lighting round is pretty punishing! Big contrast to the circuit building part where you can take your time. Personally I'd drop the time…

Not usable on mobile
From 2 comments
Any easy way to make this usable on mobile? In portrait mode things are unreadable, zoom and scrolling do not work. Landscape is even worse as everything is out of view (and…
zapkyeskrill on HNThe text is too small to read on a phone, and pinch to zoom is disabled. That's pn the first lesson

hristov on HNSome feedback: - Nice idea, though after playing Turing complete, I would like to skip the beginning and move to stuff that makes GPUs different to CPUs. But it's understandable.…

gchadwick on HNHi everyone, commenting to address feedback: - Made timed minigames optional (e.g. binary tables) - Added 7 (optional) intro levels to walk through pmos and nmos transistors -…

You need to have a, "Okay, I've tried 10 times, it's not working, what's the answer?" button. That will help not just us rubes who can't understand, but also in the off chance…

Intro or basic transistor explanations

as a learning resource, it would be great it acronyms were expanded at least once. nmos, pmos, gnd, vdd all in the first 5 seconds or so, and i didnt see anywhere that actually…

This is great! Some comments: - I didn't like the "truth tables" one, I got many duplicate questions and for some reason I got only one second for the first question. The rest of…
