How does a transistor work? Our lives depend on this device.

When I mentioned to people that I was doing a video on transistors, they would say “as in a transistor radio?” Yes! That’s exactly what I mean, but it goes so much deeper than that. After the transistor was invented in 1947 one of the first available consumer technologies it was applied to was radios, so they could be made portable and higher quality. Hence the line in ‘Brown-eyed Girl’ – “going down to the old mine with a transistor radio.”

But more important to our lives today, the transistor made possible the microcomputer revolution, and hence the Internet, and also TVs, mobile phones, fancy washing machines, dishwashers, calculators, satellites, projectors etc. etc. A transistor is based on semiconductor material, usually silicon, which is ‘doped’ with impurities to carefully change its electrical properties. These n and p-type semiconductors are then put together in different configurations to achieve a desired electrical result. And in the case of the transistor, this is to make a tiny electrical switch. These switches are then connected together to perform computations, store information, and basically make everything electrical work intelligently.

Waterproofing a watch is something that is not a DIY for at home unless you already have the tools and machinery. You can only waterproof a watch that is made to be a waterproof watch. You cannot waterproof a watch that was not intended for that.

We show the waterproofing needed when changing the battery of the watch. The gasket needing to be replaced and oiled and the crown being oiled. We check to see if everything is ok in the waterproof tester capsule. We tested my watch up to 8 atmospheres/bars.
We look for air, bubbles, anything that would show there is a leak from the crystal, crown, or case back. When everything looks perfect we take it out and re-insert the movement.

We do NOT do the test with the movement inside, in the off-chance it is not waterproof and there is a leak. Because then the movement would be damaged. So we check for leaks without the movement.
