I'm making a chamber to boil off some Cadmium that is used for brazing silver contacts onto other metals.
I UNDERSTAND THE RISKS IN DOING THIS.
The amount of Cd is upto 12%, a very small amount, I've a few of these contacts and intend to do them in small batches.
The max temperature reached...

There are many of these videos, but they all seem to have one end of the axle touching a plate.
I know the axle is a rounded ball and only fraction of it actually touches, but that is still open to friction.
Would I simply need to have magnetic...
Hi, I'm a bit of an electrical noob.
I know the basics of electronics.
Why do small metal detectors (pointers) use the powdered ferrite oxide core, but larger ones use air cores?
I've also heard that there is an option to have a ferrite core that moves in and out, but this may not be suitable...
I'm in need of a slimline bulb for my circuit.
http://catalog.miniscience.com/catalog/electricity/Light_Bulb.html
The bulbs in this link are the type that I seek.
Typically 1.5v but I'm flexible around that.
I require incandescent bulb for heat creation.
Ideally I'd like the bulbs in the link...
I would really appreciate if someone could name something similar to what I need.
A drill bit that expands to create a spherical space at the end of the drill hole (still within the drilled material).
Or perhaps a head that can tilt sideways to slowly make an expansive area at the end of the...
I've got a battery Lithium-ion, 12 hours life, 68Wh.
I'm going to use a bicycle to get around, but I'll be in remote areas so need some way to recharge it.
Solar power is inconsistent.
I've decided to use the bicycle chain removed from the rear wheel and attached to a dynamo, with a little stand...
Hello.
I'm going to purchase a large magnet (60x60mm) and cut it lengthwise (it is currently 35mm thick).
It's coated in nickle, I need to safely remove this as it could be a danger (to breathe).
I'd like to some advice on this.
Also I understand I'll need to clamp the magnet on either side as I...
