search for TOGGLE CLAMP on ebay, like this one for example:
https://www.ebay.com/itm/253323279398

these are generally what are used on professional programming and test fixtures to hold parts in place during testing.


cheers,
rob :-)

Wow, Rob, yes, those look like just the ticket. All about knowing what they call a thing. I had never heard of those before, so this is news to me. Will study these in more detail.

For now, I might steal Andy's rock idea - I have plenty of those about the place.

@Robert

I have a bunch of those (woodturning and cabinet making jigs) but I did not think to suggest them as even the small ones are a little big for what is needed.

Grogster might like them, they are very handy if setup properly.

Edit: Grogster you managed to hit reply before I sent my reply. I think you should use heavy rocks, solid gold nuggets covered in an insulator might work well

G’day grogster,

Have you thought of trying a couple of those strong magnets?

Glue one to the test pcb and use an insulated one on top of the HC12.

Just a thought.

Regards,

Mick

From memory, they are known as over-centre toggles to the mechanical engineer.A very handy concept.

I don't have a 3D printer but I sure some one here does. I borrowed plover's image.





It's inline with a reflow oven.

@Quazee137

Now that's a clever solution a nice custom printed plastic clip.

It is the ability to make little things like that that make me want to get a 3D printer. Alas I have not gone down that path yet.

So many good ideas coming being posted here. We might have to have a poll to work out which one to use!!!!

I do like Quazee137's one above.

EDIT:

@ Azure - Yes, that is also my thoughts. 3D printers are getting cheaper all the time. Perhaps sometime soon I will shell out for one.

Hi Grogs,

I've got 5 more HC-12s on the way (plus 2 USB ones).
Are you selling the PCB/Kit/Pogo pins? (I would use my own brick to hold 'em down).

More seriously, if the 5 pin header at the top of the HC-12 had a protrusion you could place the board under it and lower it down to the bottom pins. Then you would only need a smaller clip (or brick) at the bottom.

Cheers, Andrew

Hi Andrew, Where did you end up ordering the standard HC-12's from.
Thanks
