Inspired by talks at 2025's DevConf.cz, I returned home and promptly bought a second hand workstation, and then a GPU on Prime Day. The plan was not to spend a lot of money. It was not to buy the latest and greatest hardware. It was to see could be achieved on hardware that is abundant and affordable. Results have been, mixed, and at times I've asked myself if I was doing it wrong, if the hype about certain technologies (such as OpenClaw) were deserved, and whether the whole endeavour was misguided. Whilst everyone else is raving about M4 (now M5) Mac's, Framework Desktop, Dell GB10's and more, I wanted to see what I could do with US$500 and tech that there's no waiting list for. This presentation distils for everyone what I've learned, the pain points, the successes, and ultimately whether I'd do it all over again. (Spoiler - I would!)
The LM317 voltage regulator holds a steady output no matter how noisy its input — because it regulates against an internal reference, not the supply rail. Most engineers do the opposite: our self-worth tracks external inputs — reviews, promotions, applause — and browns out when they dip. This talk reads the datasheet as a psychology textbook: internal reference voltages, minimum load requirements (rest counts), and thermal shutdown as a feature, not a failure. You'll leave with a schematic for self-worth that doesn't collapse when the input does. Soldering iron optional.
