#112Huge fan of this! I love learning-by-doing and this captures that cycle perfectly.
Re: Show HN: A game where you build a GPU
#113This 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 the questions I managed to answer correctly but I still got only one start out of three? - I got very confused by the capacitor. Capacitors do not have an "enable" gate! In fact, in 2.7 (1T1C) you are supposed to build the enable gate -- wit…
Agreed, truth tables one is important. But it's backwards, you test people on truth tables before teaching them.
If someone is seeing this for the first time they may have never seen some of those gates and you quiz them.
Then finally after passing the quiz, you define NAND and NOR and Inverter.
Swap the teaching one to be the intro to the truth tables one.
Second bit of feedback is the timer. Increase the time allotted. I know them very well and still was struggling to get all the input correct before the timer hit. Or consider possibly just eliminating the timer completely - if your goal is to be sure that they know them.

progress is saved automatically, what issue are you encountering?

#115Earlier quoted context omitted.
fixed!
I've made it through about the first ten parts of section 2. Some additional feedback I've put together: * Sometimes explanations are overly lacking, other times they get repetitive. This feels like it needs to be accompanied by a course to fully deliver value. For instance, we're kind of thrown into truth gates without having really gone over them. And understanding how to combine NMOS and PMOS gates could use a bet…
Thanks for all the feedback! I've fixed some of these issues (e.g., capacitor levels, switching back to prior levels upon finishing / refreshing, deletion (theres a sign when you hover a component now)), but many of them i'll be fixing today.
I'll be uploading arcs 3 and 4 soon (which will be programming the CPU and the start of GPU arch soon (people have gone through arcs 1 and 2 slightly faster than I expected)
Re: Show HN: A game where you build a GPU
#116The 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 excludes people.
makes sense, idk if i want to remove times altogether (i personally found it fun + i want the game to be fun for all levels of familiarity), but ill add a modal to explicitly select difficulty level at the start of the racer game, i def agree w/ u overall
please just let me skip it. why am i doing homework in the middle of a game?

good point, made an update that added difficulty levels to the minigames (handles the timer), and i'll probably move the truth tables minigame to after the user builds the truth tables, thx

#118first level is impossible to solve for me! Hint or showing solution did not work! Also adding multiple sources or ground behave differently than connecting to the same.
Re: Show HN: A game where you build a GPU
#119love it, some level (full adder with 8 inputs) where a bit repetative, but it is fun.
yeah, I felt that when playing myself, do u think this level is not necessary given previous levels? (it would also help me if u indicated ur level of familiarity w/ the concepts s.t i can calibrate)

#120Earlier quoted context omitted.
I want to fix this, could you elaborate a bit (would help even more if you pressed the copy circuit and pasted the result here)
Add 2 AND gates, 1 NOT gate G0 = D0 AND SEL G1 = NOT SEL G2 = D1 AND G1 G0 -> Ans G2 -> Ans
oh its b/c of the contention between the outputs of the ands for the answer, u need an or gate to merge them (ill add an update w/ visual feedback for these sorts of thigns)
