A Moineau pump is a type of positive displacement pump with steady flow (no pulsing). This type of pump is common in the food processing industry because it can efficiently pump slurries (like soup) without crushing the contents. This one pumps 32 cc/revolution (neglecting whatever leaks back through the seals) and is capable of pumping water (milk is shown for contrast).

I thought this might be useful as a paste extruder or something of that nature. It's better than a peristaltic pump because no flexible hose is needed (which tend to reduce efficiency and wear out), plus it doesn't pulse.

Do you use solder ?

This is a stackable solder spool holder. You can make one for each of your spools of solder, and then stack them up out of the way when you are done with them !

You will need, some 1/8" (3mm) acrylic, about 7.5" by 10" of colored, and about 3.5" x 3.5" or clear. Plus some rod. I use 5/8" wooden dowel cut a little bit shorter then 3 1/4".

If you don't have a laser cutter but would like a solder spool holder, you can get the kit at SpikenzieLabs.com/catalog.

Say goodbye to SMT component identification misery with this pair of active tweezers that plug right into your trusty multimeter!

As you pick up an SMT component to put it onto the solder paste on a PCB, these tell you what the component is automatically.
