Breadboard power termination
« on: March 26, 2019, 11:45:44 am »
Hi

What does anyone do to terminate multiple power rails (e.g. 5v, +9v, 0v, -9v) for breadboards ?

I know that there are things like this https://uk.rs-online.com/web/p/breadboards/8352712/, and boards that have 4mm sockets on their baseplates, but they don't seem to add much value.

Thanks

Just stick the wires in directly.

If you are using solderless breadboards you are already in a state of sin, so one more "suboptimality" won't be noticed.

Alternatively consider that every non-soldered connection is a problem waiting to surface, so it is not a good idea to add unnecessary connections.

Have fun debugging your solderless breadboard (with parasitic and varying L,C,R); after that you can move on to debugging your circuit.
There are lies, damned lies, statistics - and ADC/DAC specs.

I discovered these recently: https://www.ebay.com/itm/3X-MB102-Breadboard-Power-Supply-Module-3-3V-5V-for-Arduino-Bread-Board/222743649206
it plugs into your breadboard and provides either 3.3v or 5v on both sides.


I ordered one. Will be here in a few weeks.

I have quite a few I’d those thanks but I’m referring to multiple rails.

Yes.  Factor in the fact that these are Chinese ones and you get to have even more fun  :)

A long time ago I used a piece of 10 pin male 2.54mm header.
Soldered 5 wires to one wire, and the 5 others to the other wire.
Because of the 10 pins and the low profile it's sits solidly in the breadboard.

Added a loop from solid 2.5qmm mains wiring.
With the loop you can easily pull it out the breadboard and it is also a GND connection for your oscilloscope, DMM, etc.
Also added a bit of yarn and glue to increase it's longevity.

Doctorandus that is brilliant.

I sometimes use these jumpers I made, I soldered on a stub of stiff wire from a resistor, for example. Plugs right into the breadboard.
