Weird theories and ideas thread! any ideas welcome

A 25-cent constant-current (CC) regulator chip would do this, as would any CC supply used for charging. :slightly_smiling_face:

It’s not a feature of the charger. It happens because it becomes harder and harder to force the requested amount of current into the cell/pack as the voltage of the cell/pack approaches the supply’s/charger’s voltage.

Stainless steel very much can and does rust. Considering the magnetic forces in proximity, all it takes is some electrolyte and ferrous material (road debris) in the water and you’ll end up with electrolysis etching as well. For fully submerged applications they typically use full-ceramic bearings for this very reason.

Ill use the thinnest high-heat hose and branch out; an octopus squirmed deep into the windings. wind the motor and hose at same time. The benefits are huge. could use a stepped-on bag of water. Cheap. Just need the thin hose and a pin. With a bike the water in the seat post is convenient using gravity.

What about an antispark switch but its connected to 2 copper bars that also complete the circuit
Attached to one of the bars is a really high resistance electronic resistor (I think this would stop almost any current travelling through it)
If the antispark ever blows then it will stop powering the resistor and the circuit will be permanently on.

That way it doesn’t kill you and afterwards you have time to fix it

More a wacky idea than a weird idea.

Pretty sure you stole this idea but ran out of tires :rofl: :

I’m doing both axles, though.

I’ll have 12 wheels, not a measly 10 like that wannabe.

Those other 6 wheels need to be hub motors for maximum speed to make up for the friction losses. And not at all because I think it would be painful to ride on 6 hub motors and thus funny

This thing is so heavy actually, there’s so much leverage going on. The chance of me breaking a baseplate just seems so high, as well as the chance of me breaking a leg or something.

I thought you were bluffing but you really went and added them onto a deck. Ride video when?

also if you think it could break an ankle then I can test it for you. My ankles can be twisted or rolled without breaking anything

not gonna ask

Someone botched a battle hardening job. took axles out of can (why?), did the epoxy, and worked the axles back in… The long way (~100mm of shaft through interference fit motor can instead of just 10-20mm of travel) … with a hammer.

The hammered shaft end mushroomed. It also got stuck halfway through the 100mm of travel to return home.

Thermal expansion tricks, penetrating oil, and an arbor press could not reseat the shaft in the can or remove it.

I unhammered it with a hammer.

This deformed the aluminum can base the steel axle sits in. (I cleaned up the mushroomed end). The can magnets now pull the stator out of parallel and it wobbles, real bad.

waste of my time, I shouldn’t have gotten involved.

I was trying to go to sleep and I had a weird idea.

What if I connect the good and bad cans with set screws, jbweld, and sweat? I have 10mm steel and could make a ~240mm shaft that ties the two cans together.

This monstrosity demands A super single (@b264). Phases in parallel too? Desync shouldn’t be a problem. Right?

Scrolling through this. Love how the app tells you individual cell voltages. thinking for the future i am imagining upgrading the cells in the same enclosure same layout of 10s1p. My cells are still good, and surely my motors will fail first but fitting some high capacity cells in here seems a dream. Still get 12mi of the 10s2p setup but its never enough :sweat_smile:

I know there’s a lot going on here, but are we not even gonna mention that stepper motor?

I think that’s a brushed DC motor from the second gen Evolve boards.

interesting, ive never seen a non stepper motor with a housing like that

For my next trick, I’ll spin a stepper with a dipsky esc. (The evolve stepper looking thing thing has three phases and sensor cable. I have another rusted one I’ll take apart for science. )

As bad and weird as this has been (the thing above did spin on a unity), I have another strange idea…





Don’t even trip, I know for a fact your M8 Wera is a lazy, jobless bum, hanging out with other vagrants like Skinny Red, and Fatboy Blue.

funny my V1 ow uses M7 head hub bolts and M9 holding the halves together.

That’s probably for non-repairability reasons if I’m to guess
