Project ideas from Hacker News discussions.

Show HN: A game where you build a GPU

📝 Discussion Summary (Click to expand)

1️⃣ Strong educational value

Users repeatedly praise the game as a great teaching tool for digital‑logic fundamentals.

"Awesome project! Reminds me of Turing Complete on Steam." — arikrahman
"The aspect that I especially like is covering the 3‑state aspect of the logic." — khedoros1
"This would be such a good game for introducing students to digital technology!" — buildbot

These snippets highlight how the game helps newcomers grasp concepts like 3‑state logic, transistor basics, and circuit construction.


2️⃣ UI/usability & functional feedback

A large chunk of the discussion is feedback on the interface and missing utilities.

"you can delete by selecting then pressing the delete button (will also allow right click to delete in the next push)" — Jaso1024
"I don’t see any button labeled that" — NooneAtAll3
"It isn’t immediately obvious that the In/Out nodes can be connected to multiple wires" — fleshers

Requests include clearer delete/right‑click support, mobile‑friendly design, and better visual cues for components.


3️⃣ Desire for expanded content & polish

Many users want more thorough explanations, optional timers, and additional levels (e.g., GPU, intro basics, acronym definitions).

"Could you expand acronyms? nmos, pmos, gnd, vdd … in the first 5 seconds" — john_strinlai
"I want to add 7 (optional) intro levels to walk through pmos and nmos transistors" — Jaso1024 (referenced as a planned update) > "I am confused about a difference in the NMOS and PMOS … why GND pulls VDD down to 0 for the NMOS, but not the PMOS" — iandev

These comments show the community’s appetite for deeper instructional material and polishing the experience before moving to GPU topics.
