What model of Fluke multimeter is that? Also is the thermocouple custom or can I buy it for my multimeter?

[CuriousInventor]

Fluke 179. K type thermocouple available from omega.

Have you just reflowed the VMeter?

[CuriousInventor]

we do small prototype batches this way, but send our larger runs.

Do you have a part# for the .0030 adapter you're using? I didn't see it in the catalog.

Also it looks like mcmaster changed the design of the pen slightly, now it's got a push button that deactivates the vacuum, instead of covering a hole.

[CuriousInventor]

We got an email saying that the part number we had may not be correct, trying to hunt down the right one! The OD on the piece in the video is .028inches.

Here's a couple of tutorials showing how to convert two readily available pumps:

The excess solder on the chip components is a reliability issue.  It will cause stress to transfer into the components, causing them to fail with vibration, movement and heat/cool cycles.

[Gort Newton]

It's not "sodder". It has an L in it and is called soLder.

Can you explain in more detail how you modified your aquarium pump to become a vacuum?

[PicknPlaceDIY]

Hello! I work on a touch solution for a machine interface and have a problem sensing multiple buttons. How do you do this? Does the µc all the work or are there other components invisible here?

It's a great tutorial! Thank you!

[HeliotropeWorks]

Haha. Tyvm for the tutorial, although I must say. Ding pop tarts anyone? The thought of seeing a squarish shape in the oven waiting for stuff to melt just makes me hungry for some reason. Keep up the good work.

Cheers

I have the Fluke 77 IV series digital multimeter...Am I able to get one of those thermocouples?
