Amplifier PCB Project V2-Adgj533

Hello Guys, I just finished the PCB using kicad. This layout is terrible I think. I don't know how to set it up properly. I have attached the zip files with all the gerber files so you can personally take a look. This is my first attempt. I will revise according to your suggestions and then send for...

Recommend a manual SMD pick and place machine?

So I build a fair bit of SMD boards by hand for testing and small runs. As things grow I'm looking to move past tweezers but still want to be able to assemble things myself with a bit of help. I saw this machine and thought that might be a nice help to help assemble things better. A lot of my boards...

Hi everyone, I'm designing an LED clock using an Arduino, 74HC595s for the control, and ULN2803s for grounding the LEDs. I've got everything working on a breadboard, designed on a schematic and a first version laid out on a pcb in Eagle. The main question I have is related to decoupling capacitors a...
