Putting Junk Mail to Excellent Use: Tony G4WIF's Proto-boards

Tony's Version of Audio Section of N6QW's LBS Receiver

Tony Fishpool, G4WIF writes:

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.

Kind regards

  1. The thought of a longboat full of Vikings getting merry on a river cruise always amuses me. Like the boards Tony. See if you can put them on a dropbox or some other public access area.

  2. Tony, Could you email me the files?


  3. Dear "Anonymous". I'll work up a web page for the proto boards and post a link here. Certainly there is lots of merriment going on with these cruises and we've done several. So really, I have paid quite a lot toward this free glossy paper!

    The top photo, in case anyone is curious, is the audio section of Pete's LBS receiver. It works pretty well.

    Kind regards
    Tony G4WIF
