I was at Vassar College in 1953. Every day, Danny Kaye would slip in to entertain several of us kids. He'd sing "Wonderful, wonderful Copenhagen." I didn't know what Copenhagen was until 1971. In a bar in Haynes Alaska I was drinking with an lumberjack who pulled out a can and took a pinch. I...

Ten years ago I had a Nissan whose lug bolts required 60 ft pounds. When it came back from a shop, I needed approximately 250 foot pounds to unscrew them. The mechanic was concerned with speed. He wanted to be sure they didn't come loose. As long as he didn't strip the bolts or snap them off, it...

I've had 3 e-bikes at once, but seemed to me that on 29 days a month, a stand would just be in my way. I don't even need a step stool to reach the rafters in my carport. That made suspension the obvious choice. I bought these. https://www.amazon.com/dp/B07FX6L3NN For each end of the bike, I used...

I don't believe the lumens figure. That's the whole amount of light. Mine advertises a 1.5 amp hour battery (about 5.4 watt hours) and 4 hours on high. That would be about 1.35 watts. I think an efficient LED produces about 100 lumens per watt, so it might produce 135 lumens on high and 68 on...

This is new to me. With the charger off, I guess it sparked because of a capacitor in the charger. Apparently, antispark connectors have a resistor path make contact before the zero-ohm path.

@harryS posted a link saying anything over 450 watts would cook that motor. Suppose you shift to a gear to let it spin fast enough to be 80% efficient. That's 360 watts of mechanical output. Suppose you can maintain 100 watts on the pedals. You've got 460 mechanical watts to take you up the...

I'm familiar with that with hub motors. If the motor is in good shape, it can escape notice. I may have had my first e-bike a year before I noticed. I don't get it pushing forward because the motor clutch doesn't engage. I think your motor would work the same way. If yours is bad enough that...

If Branson hadn't come along, those old ladies might have been swept out to sea on the rip tide!

Mine's a 2-prong, too! I should pay better attention. It's an NEMA 1-15 plug. When grounded plugs came out, the NEMA standard was the 5-15, as pictured. The 15 means a 15 amp limit. Harvey Hubble invented the plug with two parallel blades in 1910. Before there was a manufacturer's code, a...

https://www.amazon.com/dp/B0B2JT918P These are my latest headlamps. A row of lights on the side serves as a state-of-charge indicator. A long press to turn it off sets it to come on at that setting when next pressed. I'm ambivalent about the motion sensor because sometimes it comes on or off...

Me too, though I hesitated to mention it lest I expose myself as a snob. Oh, BTW, I paid $69 for mine. "If you have to ask how much, you probably can't afford it." :cool:

When you opened this topic I understood you to say the bedroom was on a fuse. That's what fooled me. Did your 1800 watt dryer have a plug like this? I'm sure it's against the National Electrical Code for a manufacturer to use a plug like this on a device that draws more than 15 amps. Even if on...

Uh-oh... I guess getting cooked would result in (9), a short or grounding in a stator winding. :)

I think the word is not "sustained" but "planned." Watts depend on voltage and power factor as well as amps. Breakers and fuses care only about amps. The NEC is about planning. It says a home circuit shouldn't be intended for more than 80% of the breaker or fuse rating. That gives the homeowner...

I know from experience that the loss of a phase through poor contact will cause a 3-phase AC motor to overheat. I wanted to be sure that this was also true of magnet (brushless DC) motors. Found it! Here are the 18 reasons a brushless DC motor may overheat...

Did you check battery terminal voltage? Naturally, charger voltage has to be a little higher than the battery it's charging. My charger reads 54.49 and charges the battery to about 54.05. Another charger is too sophisticated to measure, but it charges to about 54.45. If your charger won't get...

That rang a bell. The source I found was apparently riding an ATV. When he hit a bump such as a root, he'd get that code and the motor would shut off. When I said it was over current, I wrongly attributed it to him. He said he thought it was over voltage. He said it happened only at full...

I wonder why your display doesn't simply show the battery voltage. I wonder if all C3 displays are like that. I've put KT controllers and displays on two bikes. I'd recharge at various levels. I'd note the display voltage, remove the battery, note the multimeter voltage, charge it, note the...
