/diy/ - Do It Yourself

Hey /ohm/, beginner hobbyist with breathy LED-design from last thread here again.

As usual for my projects, this has started to get out of hands fast. I got fed up just simulating stuff in LTSpice, so I decided to dabble a little bit on PCB-design. Downloaded KiCad, watched through Getting to Blinky 4.0 by Contextual Electronics and went to town. Gonna run this through electronics department prof and see if I could get couple printed. Does it look like something I shouldnt be too much ashamed to show? Its 2-side board with front being Vcc-plane and ground-plane on bottom, all components beign trough-hole for easier soldering.

Dont mind about resistor and cap values in the schema, those are the placeholder values I got by playing with 5v simulation without additional LEDs in the circuit. I propably end up using either 1 or 2 3v coin cells. I'll play around with it when I have validated on breadboard that this thing even works, and then when I have decided on the actual LEDs im gonna put on the finished product.

Also, it took me a week to realise that I might need multimeter to do anything at home. Im so used to have one on my toolbox at work that I can borrow when needed, that would be kinda hard now that im student instead of working full-time. I could go to say hi and ask to borrow one but meh, its easier to have one of my own. Went with 50€ Tenma 72-7780, seemed like good enough piece for my needs.
