sensing cold fire

[darryl]

Woke up this AM wondering how to sense when propane is burning in a catalytic burner device. The idea is to sense the heat of the flame to verify that...

I've had a few instances where a seemingly functional furnace wouldn't fire up. In two cases I remember, the problem was that it takes time for gas to...

Is there a possibility that your wiring is too light a gauge? It doesn't take much to create a voltage drop when current is flowing.

'I am...

Last night I pinned the blankets together at the bottom edge only. This morning I just pulled on the bottom sheet, then the next blanket, then the heating...

That is easily a two wire motor. The cap can be wired permanently to the wire which turns the motor the way you want it to run. The 'other direction'...

Maybe more money is made by auctioning it off than it's worth to start with. Some kind of scam going on - everything is a scam now anyway.

Something like that- I'd think you'd want to use a shearing action to machine it.

I'm waiting for Musk to put some propellers on his cars to generate energy to run the car. The faster you go, the faster the prop turns, so the faster...

Speaking of Evan- I wonder how he's doing. Does anybody hear from him?

Nothing says you can't run it one direction only- though I don't know what use you'd put it to. Even unloaded, those motors will overheat after several...

Another thing which you could do, although this is more complicated- many of these motors will have an idle current which rises slightly as rpm increases....

I'm using mine over the top sheet- actually I have one thin blanket over the top sheet with the electric blanket over that. If I put it under the bottom...

You mentioned Maxon- this could be a three phase brushless motor, and these may run up to 60,000 rpm. If it's a brush motor, then that is unlikely. Here's...

Not a matter of national security- but since I started using this electric blanket, the bed covers will not stay in place. The blanket is very slick,...

I would have guessed them to be for plexiglass and lexan. For that you'd want tiny flats on the teeth so they wouldn't dig in. Maybe the same for thin...

You could try salad dressing- I'm not kidding. I washed my hands one day to get rid of grease. I'd usually use hand soap, sometimes dish soap, then hand...

I live pretty much on the 49th parallel, roughly the border between the USA and Canada. Visiting my sister one day and something catches my eye. We're...

You can buy ready made boards with outputs of 50 to 1000 watts quite cheaply. I wouldn't try to make that part. You normally have to come up with a suitable...

I don't see why not. If there were no atmosphere, even at that height, there would be nothing to light up when the 'solar wind' passes by. By that logic,...

Just tell them you're into colloidal silver, and you're not all blue yet-
