Thanks! I put a lot of effort into PCB design. I like cleanly structured boards ;) SMT is much easier than through the hole - if you are used to it (and I started just a half a year ago). You quickly need an hot air station - but you can get them for about 100€-150€ on ebay. The resistors are 0402 resistor arrays, you can get them at Digikey and probably Mouser. They are really handy for anything from pull up/down resistors or current limiting resistors. I think they are not very easy to solder with an iron. And they are cheap (about 1.3€ for 100).

The transistors include the current limiting base resistors internally, which I hadn't seen before. Those resistor packs are cool, too. They look like several surface mount resistors side by side, epoxied together. Yeah, really cool. The transistors include the current limiting base resistors internally, which I hadn’t seen before.

Love the symmetry of the transistors and the current limiting resistors! Yeah, I spent a while staring at this board. Love the symmetry of the transistors and the current limiting resistors!
