The Dynamo and Alternator

featured Different

So far I’ve covered batteries and mains charging, now it’s the turn of engine driven generators. In the comments on the last post Earwig took me to task over the following: This waveform is related to a basic principle of physics: moving a magnet past a wire will induce a voltage in the wire. If I’ve goofed I can’t see ... Read More »

This weeks Open Thread. A few things: 1) Sorry for the lack of Friday Funnies, but after more than 3 years with scarcely a break, I had a “Fuck it, I can’t be bothered” moment. 2) I’ve had word that the server may be upgraded sometime this week – I don’t know exactly when, but will try and give some ...

Mains Charging

featured Different

Now you know that it’s not a good idea to leave a battery discharged, you need to know how to re-charge it safely, and without causing any damage. All batteries work with Direct Current – i.e. it is always of the same polarity. Alternating Current, such as you get from the mains cannot be used – unless you rectify it ... Read More »

Friday Funnies by Microdave

featured

Something topical to start this weeks Friday Funnies: New video has emerged showing the inside of the Costa Concordia cruise ship which has been refloated after sinking two and a half years ago. It shows two Scotsmen still waiting for their change at a bar. The Beatles were lying to us all those years ago… To go with the Chicken ... Read More »

Farady Funnies by Microdave

Just a little play on words there, seeing as how I’m trying to edjurkate some of you lot in matters electrical. This is probably past its sell by date, but I either delete it or use it… I can’t imagine many youngsters visiting this establishment: Now pay attention, this is important… With built in shock absorbers, this lady obviously jumped ...

Batteries

featured Different

For this instalment of my posts about charging batteries I’m going to focus on……Batteries! If readers like Dam Langden are going to try building wind generators, then he, and you should know a little bit about what is safe, and more importantly what isn’t. I’m not particularly bothered if you kill yourself making pipe bombs, but I would rather not ... Read More »

Friday Funnies by Microdave

Featured 02-07-14

No more farting in this weeks Friday Funnies – it’ll be very dull & boring: We don’t want any accidents… Certainly not this sort: But maybe this would be O.K? By the look of things, even simple gardening tasks COULD be dangerous… Julia M posted earlier this week about another taxpayer funded crazy scheme in Sarfend – she was complaining ... Read More »

Now For Something Completely Different

featured Different

It’s fair to say that things are rather quiet around these parts at the moment – Max appears, posts a flurry of Photoshop genius and then goes into hiding again. And I haven’t the enthusiasm to do another of my “In Depth” exposés – preaching to the converted. So I was rather intrigued when Bucko gave me a “Hint” recently ... Read More »

Friday Funnies by Microdave

featured 27-04-14

Two weeks back Friday Funnies was “childish”. And so is this edition, but for a different reason. I need to “blow off” a build up of pressure. Exactly what is causing this, I’m not telling… Leggy posted about Large Arses yesterday, and quoted a health busybody claiming that “Obesity is preventable, but current policies aren’t working”. He got the second ... Read More »

This weeks Open Thread for your discussions. When (if) I’ve remembered how to do it, I’ll move the last comments from Friday Funnies here, as it’s a better place for the sort of story involved. As you’ll see I managed to move 5 comments. Please carry on with the subject here. And to “GP” who contacted me yesterday, thanks for ... Read More »
