Quickly prototype electronics by hand-milling copper-clad PCB

All you need is a magic marker, a copper-clad PCB, and something like a dremel. Isolate nodes by hand, then solder components onto the PCB. I'm probably not the first to come up with this, but I hadn't seen it before.
Advantages: easier to decypher / debug than a typical veroboard setup, everything on 1 side, isolation-distances as big as you want, components are drawin on the PCB, able to use components that don't fit into a veroboard/breadboard, and able to make low-impedance tracks where you need them.
(I made an overly looooooong video about different electronic prototyping methods earlier, but this method was not included yet. I will use it in practice now, to prototype a switchmode PSU.)

That is a good way for quickly making prototypes

[@jromhek2070]

Clever idea and I bet its faster than milling with cnc only the look isn't great . Keep up the good work .

So.. you could say that this is a MCB: Milled Circuit Board!

Why not use breadboard?

[@mramakers]

I often use breadboard too, for example to test something. This soldering-method here is a bit more robust, which can be useful e.g. when you have to take it elsewhere. Stuff doesn't fall off when you shake it hard.

And breadboards have high capacitance

thats rough better using a printer
