What's the matter?
I often experimented with electronics, and got to love the atiny85, its cheap its easy to program there is a gcc toolchain (avr-gcc) so i could program it without some crapy IDE, just using my beloved vim editor. But whats an atiny without a bunch of Mosfets?! We want to controll the big energies of the Universum 🌩, well because you know..., it's fun😀.
Then some cheap LED-Strips came throught my hands and I wanted to make a little PWM controller for the strips. Because who doesn't like blinky RGB's. S o i desided to fresh up my KiCad skills and designed a board for 1 attiny and 3 mosfets plus a voltage regualtor (however i like to call them voltage burn er 🔥). I ordered some of JLPCB, because you can use those for A LOT of things. But yeah the design is pretty basic and, the mosfets are multi-dimensional overpow ered, but that does not matter because i want them to be used for multiple purposes.

Uses
As said i used it for an fancy RGB controller which worked out nice, and should get its own post any time soon. I also used it for a couple of other th ings, one of them being a air dryer for seasonings. I was very happi having those pcbs laying arround, because it speed up the development process enormously.
