Sharkbomb Audio 5 watt special build: Design process

Sharkbomb Audio 5 watt special build: Design process

Building the board this way was extremely difficult and time consuming, but it produced a good looking board.

Drawing the layout

To draw the layout, I used my Ipad and apple pencil and drew every component by hand and drew all of the connections. I also tried using a program called DIYLC to create a layout, but it was extremely difficult to use (in my opinion) and the layout ended up quite messy. This is why I went the ipad route. It created a semi-clean looking layout that I was able to take and create my board based off of.

Creating the board

To create the board I used Eagle, my PCB cad program of choice. Eagle isn't really meant for creating eyelet boards, so I kinda had to work around the limitations within my program. To do this, I made the base PCB the size I wanted it and created the schematic to mimic the layout and added some large eyelet-style holes that an eyelet/turret can fit into. I then put this all on a 2mm thick board with giant traces to cary the signal and high voltage. Below is a picture of both the CAD drawing of my board, as well as a picture of what my board looks like unpopulated and fabricated from JLCPCB.
