It seems that any time you have a circuit on the bench, there’s wires. Lots of wires. If you are working on something new, it is a good bet that some of those wires are clipped to other wires using some field expedient, especially the power wires. We often have an alligator clip awkwardly grabbing the shell of a BNC. [Felicitus] got tired of this, so he created Monsieur Adaptateur, a breakout board that has common connectors you’ll need when working on a prototype.
What kind of connectors?
- DC Jack 2.1mm
- 2mm Jacks
- 4mm Jacks
- BNC Connector
- Terminal Block
- Scope probe connector
- Standard 6 pin 0.1″ female header
- Standard 6 pin 0.1″ male header
- 4.75 and 6.3mm blade connectors
The dual conductor items (like the 2.1mm jack and the BNC) connect to both sides of the board. The other connectors are in pairs. The idea is you can connect, for example, a BNC cable from a signal generator to some jumper wires on the male header, connect the scope to the scope probe connector, and still have the banana jacks to hook up, say, a digital meter.
No one would say this is going to change the world, but this is one of those things that is simple, but very useful. The plans are all on Github, and obviously you could adapt it with connectors that make sense for your specific situation.
We aren’t sure this board can tame a wiring snarl like in the video, and it won’t help you do a neat wiring job with hundreds of wires, but it couldn’t hurt.
Very good idea. I could use one or two of these to make breadboarding circuits easier.
two alligator clips soldered would be nice, very cool indeed.
BNC for power supply ?
Yup. Not uncommon in some circles.
I don’t think it is just for power supply. The RF connector is probably there so you can use some multi meter probes or clips and then use a BNC to BNC lead to a scope or some other test equipment.
An SMA [male] and SMA [female] would help reduce my collection of adapters. Especially if I want to tee off a sample for my scope – or inject from a sig gen.
What! No PL-258 for DC?

Please sell these, even as kits, for those who don’t want to spend the time finding and ordering parts along with having a PCB made.
It is for sale, https://www.tindie.com/products/Felicitus/moniseur-adaptateur/
You wouldn’t want to drop it on the floor. It looks like it’s made to take deep flesh ankle biopsies. lol
Cool and all, but I’m not jazzed about a bunch of unterminated connections floating about especially when hooking things up to a scope or similar circuit.
It’s one of those things that has some useful features and makes life easier until the one project where it matters and you spend a day troubleshooting issues you shouldn’t have had in the first place.
Where do you get those scope probe connectors?
Never mind – they’re not what I thought they were. Sorry.
