This was super fun! I kinda love the idea of designing my own paths and board placements from scratch. Especially as later I can even get artistic with it and try to draw images using the paths… but that’s a little deep down the rabbit hole. For now I’m content with getting all three of these together with only one Via. The last one was pretty complex and I couldn’t find a way to reroute it. Luckily one simple via is quite fine and easy to wrap my head around. Also, I did quite like making the paths curvy in the last one.
Got this tiny lil thing soldered together and got a light blinking, not sure why it's blinking at 1/10th time... did the beep test and nothing was short circuited. So small! I also think I did the wrong thing and soldered the ATtiny direct to the board.
