It's useful to have those dupont connectors on the end so that you can plug in the soldered part of the board connection which then becomes sacrificial, rather than having to rebuild the probe tip soldered parts. It looks like you have to sacrifice a probe to the technique though - I guess you have spares. I did think it would be cool to use a female co-ax terminator given that probe comes apart but of course you then lose the x1/x10 feature of the probe

Scope capture of the Arduino USB clock:

I used AC coupling because my scope's trigger doesn't deal well with MHz range signals with DC offset.
Standard acquisition settings, and using the hardware frequency counter.
This image will not be better than using the pig-tail probing technique. But it offers hands-free operation.
It's definitely better compared to using the crocodile probe ground lead.

Hi Jan,

Nice work, it got me thinking, it would be cool to one day see a Project14 month on say test leads, probes or electrical connecting/clamping ideas. there are probably so many tricks or alternative uses for component wires, connectors, heatshrink!, that people forget about.

Also, I just remembered there's an elastic sleeve that used to be quite popular (I think heatshrink has overtaken it in most scenarios though), that could be an option to keep the wire loop snug.
