But I did not find it in the episodes list (http://eevblog.com/episodes), but needed to use Google to find it. Looks like anything before episode #101 is missing (its the first in the list). Since I use this page once in a while as reference, it would be nice if its completeThanks,hli

content: QuoteThere are several types of approaches... more serious, more idiotic ones.The best one is the principle a online-USV uses, create a complete new AC. Depending on the quality of the unit this can be more or less noisy.Other products do other things, like loading with resistors to "symetrize" (or do whatever) the AC. Reshape the AC by adding the chopped caps of the sine-wave (normally they are chopped of by the rectifiers of SPSUs), create blue light...Anyway, if you really need such a Unit for Home-Audio, you either life (electrically wise) in a 3rd world country and will have much more serious problems or... you don't need it

timestamp: October 20, 2013, 03:57:24 pm
content: So I could surely use some basics on workplace safety. Also I'd like to understand why and when each of the specific precautions is need. So far I just used common sense and my general knowledge from my few labs in college. I never got hurt and want to keep it that way. I think that most hobbyists come to the point where the build or troubleshoot main voltage devices. I surely tinkered with the lighting and mains wiring around my house. Also I built and troubleshooted a few devices pored by the mains. If I do the troubleshooting part more often I think I'll need an isolation transformer. Also I'd like a breaker circuit and an extra fast fuse for my bench.But I find it very difficult to wrap my head around it in the limited time I have for my hobby and still get stuff done. Also it's not the easiest of tasks to separate the overkill from the really useful advise. So I'd be thankful for a good basic introduction to workplace safety focused on mains voltages and the electronic hobbyist.If you, Dave, are not interested in doing such a video, I'd be happy for someone to point me towards good tutorials and equipment to have. I still feel a bit lost on the topic.Thanks for your attention.

content: I completely agree with Dave regarding the ridiculous small flag connectors for camcorders. I bought a $1200 camcorder quite a number of years back that had one. While video taping a graduation I had it on a tripod and plugged into a power outlet. I turned the handle to raise the height of the camcorder but didn't realize I was standing on the cord. It immediately snapped the connector off the end of the power supply cord, at the camera. Replacement cost... $125. Had to buy a generic aftermarket for $80. Expensive lesson for sure.

In order to get balanced and matched tubes, it is necessary to test tubes at the maximum rated voltage and amperage. Up until yesterday, I thought I was going to spend a painful amount on a power supply that would give me up to 350v and 350ma. I just went on EBAY and got one for $12 and $15 freight. The best part of it is, I went to the manufacturer web site and it's a current model and sells for $1834US

Episode Idea: Lightning and protection systems - Page 1

author_rank: Contributor
timestamp: September 19, 2013, 12:18:42 pm
content: Hello Dave!An idea for an episode just occurred to me, though it's not about electronics per se but about electrical engineering. I would love to hear your insights on lightning protection systems both large-scale and for the home. There are domestic products out there that claim can protect your appliances from lightning, but based on actual strikes and their aftermath I remain very skeptical about their effectiveness. I would buy that a proper lightning rod installed at a well-studied location is a good protection, but what can you do to protect a suburb/rural house without tall skyscrapers nearby to take the hit for you? When lightning hits a tree, the effects are quite nasty, especially for the house next to it... Even if your electrical installation were completely isolated, a surge could travel through your (TV/Internet) cable, phone line, etc. For example, would the devices powered by an isolated domestic UPS get any acceptable degree of protection against lightning, say that hits the front yard tree? How far from the "epicenter" does the danger extend?Thank you in advance and I look forward to more awesome material from your vblog!Nil
