Re: #Cubic_Circuit_Layout #cubic_circuit_layout

 

This type of interconnect makes a lot of sense. I used it many times in the past with industrial products and the products were very stable both mechanically and electrically. Modular design has many advantages for products that offer multiple hardware options. Perhaps we can start by figuring out the board dimensions and match to potential standard metal or plastic cases.

I took the suggestion of John VK6JY and used connectors on each end of the
proto-boards.? This means the boards can be stacked or plugged together in an
offset layout.?

A block of 5 prototype boards with connectors soldered in place and the boards plugged
together.

Alternative configuration to allow taller components on some boards.

Actually I am rather happy with the way this worked out.? Next question is "what to build
on my modular cube?".? I ohmed out all the pins and have connectivity where it should
be and no shorts where they should not be any.? Doing this again I might cut the pins a
bit shorter because the socket sides do not press all the way down to the board surface.

The slightly more expensive boards with plated-through holes should be even better.? I
have some of those on order from Ebay vendors.

The idea is to build circuits in modular form so that sections can be rebuilt or replaced
without disturbing the whole circuit.? Power and control signals will be via the connectors
and signals (RF, IF, AF, etc) will be connected by small coaxial plug lines along the edges
of each board.
