Great post! I’m an ex maths/physics person and have always been into EE and electronics as a hobby. I’m currently working on a pcb and am also struggling to find that leap in knowledge. I have recently found the eevblog forums [#] which are extremely valuable. I haven’t posted there yet but am planning on engaging and seeing if I can learn some deeper knowledge. I’m struggling to pick which MCU to use exactly. Let alone what brands of rotary encoders are good, or which water proof usbC female port I should use!

All the parts from Mouser or Digikey are good. It takes time to find your favorite vendors, parts and most enjoyable datasheets. Part picking process is very time consuming.

  Any tips if I wanted to get something pre manufactured through the big pcb players? How to figure out what parts are in stock, what can be used with each other. Any tips for beginners? I’m looking to get a pcb with parts soldered on (ws2812 LEDs, atmega328 and supporting parts. Is this easy and feasible to do?

    I do my assemblies by myself. It’s faster and more convenient during prototyping stage. While the boards alone cost 400€, with assembly it might cost 4000€. First revision has errors and it’s a waste of 4000€ then. I can recommend in Germany Beta LAYOUT GmbH. They do usual boards for good price with good quality. Be aware, that nobody wants waste the time with 1500€ first order with assembly of 5 boards. Maybe you can find some student willing to play with electronics on weekend for cheap. And yeeah, maybe overseas is cheaper. But I don’t do that anymore.

    I have not put in an order yet, but I am looking at JLCPCB which seems to have a wide-ish variety (not like mouser or digikey but still, most things available) of parts at reasonable prices. I am designing with their partslist in mind so that they can assemble for me especially the tiny SMT stuff that I have no hope of doing myself. I think you may need to pay a bit of extra fees if you don't use their "in house" parts but so far it looks reasonable.
