As a result, the idea languished for a long time. It took several decades for a handful of dedicated persons — infatuated with the mysteries of electricity and magnetism — to finally put the theory on a solid footing. Nixies were introduced when vacuum tube hardware automatically provided the high voltage they require.

Here are three transformer based ways to obtain that high voltage in line-powered semiconductor-based devices. Signal generators are devices used to make the signals used in testing and troubleshooting of radio receivers and other circuits, so are of primary interest to almost everyone interested in electronics.

I love restoring old electronic equipment. A while ago, I was excited to find a vintage Heathkit EC-1 analog computer for a reasonable price on eBay. It definitely needed a little TLC. In the US, the DC volt is legally defined by the Josephson array — a super conducting quantum device with a highly repeatable output voltage.

Banks of standard cells and temperature-stabilized zener diode references are used by the National Institute of Science and Technology NIST to calibrate DC meters for scientific and industrial customers.

So how is the AC volt defined? Other Please indicate the type of request. Details of request Please indicate a detailed description. Login Close the form without saving We could not find your subscription. Please try again.

It's from article. They seem to be looking for a mythical universal motor-controller that interfaces to Stamps, controls any motor from 0. Will that be good rule of thumb for awhile? Parallax has a nice Propeller-based dual H-bridge motor controller that handles up to 10A.

Does that violate your "rule of thumb"? I hope not. I suspect that V is a good range for maximum voltage That's a lot of battery, maybe not quite so big if you have a big robot. Parallax's Arlo motors can draw over 8A at 12V under heavy load. Drawing these "lines" is complicated by the fuzziness in the definitions involved. Best to explain the circumstances you're trying to discuss and avoid hard "lines" except where you're talking about Absolute Maximum or Minimum specifications in a datasheet.

Thank Mike 'Fractional horsepower'. Here's another example of a 'as a general rule'. Fractional are for hobby and 1 hp and above you are getting into industrial. I figured out to look at Craftsman bench top power tools. Radial saw, band saw etc. Let me check that out. I would say they are non hobby. They are AC too.
