Manhattan-Style Circuit in a Copper Cladding Chassis

Yesterday, we posted about a technique used in ham radio to solder together project boxes/radio chassis using PCB copper cladding. Some folks, in comments and on the twitters, were wondering how well this works. Take a look. Here’s a lovely Wheatstone Bridge Regenerative (WBR) Receiver built inside of such a chassis using the Manhattan-style circuit construction technique (using small pads as connecting points on a conductive surface).

As somebody said in the comments to the chassis piece, imagine some lovely copper etching on the faceplate.

BTW: Here are some MeSquares and MePads you can get for easy Manhattan circuit building. We’ve mentioned them here before. [Thanks, Roy Roberts!]

  1. Absolutely beautiful – you do excellent work.
    I do wonder a bit about microphonics from that suspended toroid, however. 
    …or does the thick tap provide enough stability that it isn’t an issue?

    I also really like the idea of etching the front panel with labels that will never rub off and/or decorative patterns, while still maintaining the shielding afforded by the inner layer of the board.  In conjunction with dying the underlying board in a contrasting color, that could really have some fun possibilities.
