Thanks! The aquarium pump that I have is different mechanically, the entire pump's interior served as an inlet. So, I made a chamber around the inlet valve and attached the additional pipe. The result was too weak to pick-up 0805 components (Uncilife Aquarium 1.8 L/min). So, I simply bought for $10 a 12V 3.2LPM pump that already has an inlet attachment. The rest is identical to your setup, and it works really well! The rubber hose that I have is too soft, so if I want to increase the vacuum power further I should use a shorter piece, I think.
Oops - almost forgot - Stuff a piece of balled up foam inside the pen before you put it together to act as a filter in case you accidentally suck up a part or other small object instead of having to take apart the pump! (Don't ask me how I know this is a good idea!)
Are you sure the 10 gallon version have enough vacuum suction? I have exact same box as your and not enough suction to pick up anything even a paper ....I saw othere UA-cam by someone using 40 gallon version of the same product
The Tetra 10-gallon aquarium pump is the one that I am using in the last chapter of the video to pick up an assortment of surface-mount components ranging in size from an 0402 capacitor to a 64-pin TQFP. As you can see in the video, the 10-gallon one does work with the right needle or needle plus suction cup for the component that you are picking up. I was able to pick up the 64-pin TQFP with the nylon luer adaper by itself, so the vacuum seems quite reasonable to me. I have also used one of the Tetra 10- to 20-gallon aquarium pumps. That is the one that I have used most frequently to assemble my boards. Comparing the two pumps side-by-side on the same set of components, the 10- to 20-gallon pump does a better job than the 10-gallon one. If you can't pick anything up at all with the 10-gallon one, it may be that you lost one of the O-rings when you reversed the valve in the pump. I managed to do that with one of the larger Tetra pumps (40 - 60 gallons), which had two one-way valves and two output ports. After I had reversed both valves and reassembled the case, I found one port was pulling a vacuum while the other was not. I opened the pump back up and found that one of the O-rings was missing on the side that was not pulling a vacuum. I measured the dimensions of the corresponding O-ring from the other valve (it was a #011 with cs = 0.070in, id = 0.301in, and od = 0.441in), and I was able to find a suitable replacement at my local home improvement store. That fixed the issue and I have used that one for two people to assemble boards at the same time.
I really like your handpiece design - I can't wait to try it here on my setup (which is currently using a vacuum pump from amazon and a hacked up syringe for a handpiece). Great job, but PLEASE get a real screwdriver - it's hard to watch you struggle! Thanks for doing the video...

Great, thanks. But get a regular screwdriver...
