I need a better (cheap) probe(holder) for measuring signals on arbitrary devices

@howardlong  I like that DIY probe holder of yours!  I'll give that a try too.

This guy from Teledyne-Lecroy has the Jaguar of probe and work clamps, it has a micrometer adjustment to move the probe tip up and down to touch the work.

One of the best methods for positioning arbitrary things is to use the liquid cooling "hose" from a lathe.

They show attachments for oscilloscope probes and such if you read the tutorial.

While not a micrometer adjustment, the $15 magnetic-base dial holder I'm using has a knob that allow you to achieve the same goal of adjusting pressure/moving the tip down nicely:



EDIT: The magnet part isn't used for me at least, as don't have a steel workstation! But the base is very heavy so all you need for holding a scope probe. Just keep it turned 'off' to make it more difficult to bring near your hard drive...

I find these useless for precision work. Or at least the set I got from Sparkfun. They are super rigid so when once set you try and move them a milimeter, you push and push until it goes clank... and jumps half an inch. Tried lubricating and what not to no avail...

The bast probe holder is the lab assistant. Since companies tend to be frugal, and dont spend money to get us help, technicians, lab assistants, secretaries and or even apprentices, we use other engineers to hold the probe. Even though they are kinda over qualified to do that. They also complain a lot more.
