How we built a Super Nintendo out of a wireless keyboard (2012)
In this technical retrospective (2018), @lelf shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

It looks like the company sifteo was aquihired and the cubes software wad opensourced but the actual hardware is now scarce. Just reading this article makes me fascinated with the project and as I have a young daughter who would probably benefit from a tactile gaming system like this I wonder how feasible it would be to resume production of the cubes or even hand craft them from components. I didn't see open CAD files on the GitHub repo but I did notice a UK professor has compiled all of the software and games and modded it to work without their central server. I doubt I have the time to mess with this anytime soon but it seems like it would be a awesome project to restart as a maker/hobbyist initiative.
I’ve been really into the nRF52832 lately, a newer chip from the same company as the nRF24LE1 mentioned in the article. It has BLE, and you can find dev boards with all of the IO pins exposed for $5 (sometimes $2.50 on sale) on AliExpress, or impossibly tiny ones with chip antennas (six fit on a dime!) for closer to $15.
I just realized that the ones I have sitting around have roughly 64x the RAM, 32x the storage, and are (VERY roughly, I had trouble finding compatible numbers) 2,000 times as powerful processors. There’s so much more they could be doing!
The author of that article, Scanlime, is scary talented. They have a lot of videos up on YouTube that are a treat to watch.
It wasn't a Super Nintendo, and it wasn't built out of a wireless keyboard. Quality title.
