Mike - that's a very neat construction indeed. Mind if I ask for some pointers:
* What brand of preformed jumpers do you use? I tried the Elenco ones and could never get them to fit, so instead just use flexible wire.
* What brand of breadboard?
* How do you connect up power, signal, scope probes, and things like speakers which don't fit into a breadboard? I use alligator clips attached to jumper wires which I insert, and so I end up having 4 or 5 of these hanging off the board.
hi,
I fix my project boards to double sided pcb [use off cuts]
Cut the pcb so you have about 1 inch oversized on the project board, that is a 1 inch pcb border.
Solder 0V/Gnd wires to the pcb and push the other end of the wires into the project rails you plan to use a the 0V rails.
You now have a grounded back plane.
Use short lengths of terminal strips, the type you normally screw to a panel and has vertical tags to which you solder wires.
Solder the terminal fixing tags to the pcb [ all on the top side of the pcb!]
Use the 'free' terminal tags to connect long twisted wires to your bench power supply.
From these tags solder power wires and push the free ends into the project board lines that you are using as power rails.
Now solder on the terminal strip electrolytic and ceramic decoupling caps, using the pcb as 0V/gnd.
I usually mount two project boards on one back plane pcb, sometimes 3.
This gives a firm base for holding the project boards together, especially when connecting wires from one project board to another.
I use these boards for work from mVolts analog signals, digital logic/PICs upto 20MHz with NO problems.
I hate to admit this but my project boards have been in regular use for about 20 years, bought from Jermyn industries.
Always use clean, short lengths of TINNED solid copper wire for the interconnections. Use old telephone wire.
DONT force in oversized component leads.
If the passive components you use are on 'strips', cut off the end bit of wire thats covered by the strip..
Some strips leave a tacky residue on the wire, you dont want that in your sockets.
OK.?
EDIT: at the other end of the pcb I solder another terminal tag strip.
I use this to wire test leads into the project board and the scope/meter hang on this terminal strip.
