OT- earth from deep space

The worst part of it is if the battery is left in. The water itself can be dried away, but there could be damage done to the circuitry if electrolysis...

Pump it up and then try breaking the bead in the press....

The 'old' transformers were iron- the 'new' switching ones are ferrite. You would not use ferrite for a magnetic chuck.

My thinking in this...

So really the key to moving around in the universe in 'the big boys club' is to lose all mass. At that moment, time is immaterial, and the past, present,...

Ha ha- good one. We've already pointed out 'antennas' towards earth, and been hard-pressed to find intelligent life. We find technically advanced life-...

A microwave oven transformer should have maybe a hundred ohms on the secondary, and maybe 1 ohm on the primary. There is another winding which is two...

I remember when stove pipe would snap together properly. You had to work at it to get it to come apart....

The fact that my friend can access something on my computer from afar, yet I can't from sitting right in front of it is a little disconcerting. Mind you,...

Obviously we can't say whether another civilization is more advanced than ours or not- we could assume that it must be so, based solely on the assumption...

Just watching unsolved mysteries of the universe, something like that. The talk was about earth-like planets, potential habitable zones, etc. Got to wondering-...

I was just wondering about the possibility of using a train wheel as a flywheel, then I'm reminded of the idea I had to use a coil of steel cable as the...

Can't really tell from the picture, but the analog current regulator chip could be there- it's about the same size as the bridge rectifier you do see...

What you could do is temporarily put a resistor in place of the test lead, then check the voltages on the other strings. Chances are the voltage across...

With that many leds in total, it's unclear what the full connection is. But if you get it to work with a short as you show, then a 20 ohm resistor should...

Kind of a follow-on to the favorite authors thread. I've been browsing through some old magazines- here's a few excerpts that made me smile.

We were taught to not open the fridge or freezer if the power went out. Our freezer wasn't bad- it had top doors, and six of them. Opening one didn't...

flight sim- that's what got me interested enough in computers to actually buy one....

Here's one- again I don't have the model truck, but when I was two I got a metal toy truck that was a '52 international- same truck my dad actually drove....

There was a paperback which for some reason I quite enjoyed, called Moon Castle. Don't know who wrote it, but I know I read it several times. In the electronics...

Well my jaw isn't so rigid, and the enamel inserts aren't in very good shape, but some of them are sharp.
