Ion gauges on one of our deposition systems.
Ionization gauges are commonly used to measure pressure in high vacuum. They look and operate very much like a light bulb. Electrons are emitted from a central heated filament (the glowing part) and accelerated toward a helical wire or “grid” around the filament. Some of these electrons collide with gas molecules and ionize them. The ions are then attracted to a collector filament, creating a current which can be measured. The magnitude of the ion current depends on the pressure and composition of the gas.

Why I haven’t posted that much last week :P
Small Buddy drawing using Procreate. It works pretty much the same as Photoshop but I’m still trying to figure out how to handle the glows

Upcycling never looked so good…
Amazing idea! Plus with the right stand you can make this look awesome. People are getting create with light bulbs these days.
This is really creative. A wonderful idea that will surely catches visitor’s attention

If Ben Franklin didn’t invent the light bulb certainly others would have done it but when?
Recently we stumbled upon this cheap high voltage converter on Amazon which claims a boost from 3-6V to 400kV.
Although really skeptical about the 400kV claim, a lot of comments indicated that it did boost at the very least to 10kV so we got one of these to test it out.

Using a 3V battery to power the circuit
And boom! There we go, that’s how you light up a CFL light bulb using a 3V battery!
If you do have access to a plasma globe or a tesla coil, things become a little bit more simpler:
Wireless (but not free) means to power a CFL light bulb
The way CFL light bulbs works is by exciting the electrons in the lamp and when they return to the ground state they radiate ultraviolet light. This emitted light is converted to visible light when it strikes the fluorescent coating on the glass.
So it really does not matter how you decide to excite the electrons to the higher energy state. It might be a high voltage converter, a tesla coil, a plasma globe, etc but all you need is a device that will kick those electrons inside the bulb from their ground state to the higher excite state. That’s all you need!
Have a great day!
