I’ve been intrigued by Pete’s matrix pad method. Of course, few of us have the machinery to mill them as Pete does, but etching is a possibility. Now some of Pete’s boards clearly have a lot of noodling behind them. His boards are quite big with little areas of pads and space between. The layout for the whole project has clearly been considered in advance.
I wanted a board that I could make modular, take little time to etch and adapt for the circumstances. These “proto-boards” are the result.
The project is Farhan’s “sweeperino” and one board is for the Si570, and the other the AD8307.
The Si570 board is now complete and working:
The PCB method is pure Chuck Adams. His videos on YouTube describe the toner transfer method better than I could.
The only difference for me is that my glossy paper comes free from travel agent brochures.
Just express a passing interest in Viking River Cruises and you will never pay for PCB paper ever again!
There is a free printing only version of the software I use, so if SolderSmoke listeners want to use the proto-board design, I will happily email them the files.
