> [@bing](#): > > I don’t know why this is so difficult a concept to explain but engines, engines. It must have an engine. And it must use gas, diesel or something similar. And you also need to have to change the oil once in a while. Not electric or atomic or sun powered, but an engine. You do realize that the word “engine” predates the invention of both gasoline and steam engines? ---

> [@chunkyazian](#): > > You want to have the motor spin up and generate a counter voltage ASAP. In this condition, the winding sees a low amount of total voltage thus generates a small amount of wasted heat. By using a multi speed transmission, you rely on torque multiplication rather than inefficient high current to accelerate. It also limits the amount of time the motor would operate in the low efficiency range. In real world driving, you limit the amount of amp draw by accelerating gently from a dead stop, which partially at least, renders the advantage of a multispeed gearbox moot. Where I live, Tesla roadsters nearly outnumber the Priuses, and I rarely see the drivers of those cars trying to prove to the world how fast they can accelerate. ---

Agreed, if your real world driving is mostly on flat terrain. In one of my work projects, we had powered a 3v stepper motor with 12v simply by turning off 3/4 of the duty cycles using code On hills, you are going to use a heavy foot on the go pedal. I think it’s better to use gears for torque multiplication rather than high current. This is especially true for something utilitarian such as the cyber truck. ---

Modern DC chopper motor speed controls are not necessarily drawing high current from the batteries when they are delivering low voltage/high current to the motor during low speed use. They are kind of like DC to DC transformers in that respect. High voltage/low amps in, low voltage/high amps out. Stepped ratio gearboxes may have made sense in primitive EVs that controlled power with rheostats. ---

Henry Ford took apart his mother’s or grandmother’s sewing machine just to see and put it back together again. I wonder if there are any enterprising young Henrys taking apart their mother’s machines. They have neat little motors and a foot pedal. Of course 110V but that can be fixed. I’d never allow one of those to be thrown out without salvaging the motor. ---

I still do it. Almost nothing of any consequence gets disposed of without first disassembling it to see how it was designed and built. I fix all kinds of things most people would throw out just because of the satisfaction of doing it. ---

I sure can relate Mr @TwinTurbo and @B.L.E … I consider that practice one of the first classes that are held in The School of Old. Ah yes, I have fond memories from the days of “The Old School”… Now if I could only recall the school theme song the cheerleaders used to sing, but it eludes me at present. ---

My childhood friend Lewis and I disassembled old watches together to see how they worked, and coincidentally, my paternal grandmother often boasted she could completely disassemble and reassemble a Model T Ford and a Model A Ford when she was a child. ---

The next natural question @Whitey would be if those watches could keep time after those disassembly events? Or were they perfectly correct only twice a day after that? lol jk ---

Lewis’ parents knew better than to give us working watches, and we pretty much destroyed them in the process. ---

I disassembled a lot of things as a kid and made a lot of junk. Seriously, many years ago a little boy across the street came over to my house and asked If I could fix his bike. I asked him if his daddy could no fix it. He said " All my daddy has is a hammer and I don’t want him to hit it! " ---

Didn’t bother to save or re-apply the front skin. My older brother bought it at the Navy PX for $64 in the late '60s. ---

> [@circuitsmith](#): > > Here’s my first camera: I have the exact camera, but that one looks a little funky with that raw metal gizmo around the lens… I’ll have to look at mine when/if I go back north, if/when the state opens up, again. I bought mine new, don’t remember what I paid (receipt is probably with the camera), and I bought a _Gossen Luna Pro_ light meter to go with it. Time exposure night scenes were fun. I was into black and white photography and darkroom work. I had 35mm cameras, too, but those 2-1/4" square negatives were nice for big enlargements, 11X14 and 16X20 and that camera did a decent job. _ **CSA** _ 🌴 🕶 🌴 ---
