Vacuum therapy device arrived. It gives my tits such a satisfying shape.

#Vacuumpump 1876 #museumscienceindustry @msichicago Heinrich Geissler invented the mercury displacement pump in 1855[10] and achieved a record vacuum of about 10 Pa (0.1 Torr). A number of electrical properties become observable at this vacuum level, and this renewed interest in vacuum. This, in turn, led to the development of the vacuum tube.[11] The Sprengel pump was a widely used vacuum producer of this time.[10]

So I finally bought a #HeatPump for the back yard shed. It’s a little one - the space is pretty small. I wanted to do this years ago, but the industry dragged its damned feet catching up with the science.

Intent is to DIY it. But the instructions say I need some tools I don’t have. #ManifoldGauge set & #VacuumPump

Maybe I’ll DIY all but the final steps, then hire that last bit.

Or maybe the cheapest #HarborFreight set will be cheaper than the labor cost.

What did you do on yours, Fedi-folk?

#skoolie issue; hard braking after many little brake presses.
and funny noise coming from the #vacuumPump.
I had no problem diagnosing the problem. fig 1 shows the problem, a spring coming out of the top of the pump. After releasing the tension on the belt, unbolting the pump I was able to pull off the pulley.
My issue is that I saw a little rust on the shaft and corresponding rust on the pulley.

Do I need to worry about this?
Is there any tricks to getting the pulley back on the new pump?

Researchers 3D print a miniature vacuum pump

Mass spectrometers are extremely precise chemical analyzers that have many applications, from evaluating the safety of drinking water to detecting toxins in a patient's blood. But building an inexpensive, portable mass spectrometer that could be deployed in remote locations remains a challenge, partly due to the difficulty of miniaturizing the vacuum pump it needs to operate at a low cost.

Hackaday Prize 2022: Salvaged Pumps and Hoses Make a Neat Vacuum Pickup Tool

Anyone who's ever assembled a PCB full of tiny SMD parts will have found that tweezers are not always the best tool when it comes to accurate positioning. Thin, flat components like microcontrollers can be awkward to pick up securely, while small resistors and capacitors have a tendency of snapping out of your tweezers' grip and flying off into the sunset (or your carpet). Vacuum pickup tools can be a great help, but the most convenient models, with an electric air pump and a foot switch, can be a bit expensive. [sjm4306] shows that it doesn't have to be that way: he built his "VacPen" mostly from reused components.

At the heart of the project is a little vacuum pump with a pen-like device hooked up to it through a flexible hose. The tip of the pen holds a pickup nozzle that came from a cheap manual pick and place tool. Both the pump and pen were salvaged from some gas analysis instrument that [sjm4306] tore apart a long time ago; the pen is especially convenient since it comes with a built-in brush-like filter that can trap any debris or tiny parts that might be accidentally swallowed.

The VacPen controller is housed inside a neat 3D printed enclosure that holds a custom PCB with an ATtiny microcontroller. The pump can be operated either through a foot switch, or by pressing on the touch-sensitive pad on top of the enclosure. [sjm4306] made this by soldering a wire to a copper penny and sticking it on the inside of the lid: simple, effective and cheap.

As you can see in the video embedded below, the VacPen is perfectly capable of picking up any kind of SMD component, and just as importantly, immediately releasing it at the desired moment. If you're new to SMD technology, we can recommend this tutorial by [Bil Herd] that covers vacuum tweezers as well. If you're more into automating vacuum pickup tools, this cool robot might be of your interest.
