This is Hacker News. Open source is generally appreciated here even when there isn't a direct, concrete benefit to most end users.

But if you're here, there's a good chance you're the sort of person who could get an AVR programmer and tweak something if you don't like it. Different modes? Timed stepdowns to prevent overheating or not, or more sophisticated thermal regulation for the attiny25 based drivers that have a temperature sensor? A firmware with completely different behavior like near-continuous ramping instead of fixed modes?

It's hackable, and hackable is good.
