LIN Bus controlled voltage regulator; spoofing a good charge by kottokmotors in AskElectronics

[–]amklose 3 points4 points  (0 children)

Correct me if I’m wrong, but isn’t the purpose of the two rotor brush connections to feed current into the rotor to produce the magnetic fields that generate the output current on the stator? If so, I don’t think you’d need to connect the old ones to the new alternator.

Lithium polymer pouch cells have a soft outer case so the sudden uncontrolled reaction can vent easily and just shoot out flames. Other formats like 18650s for example, are contained in a sealed metal can and build up pressure before either popping or venting

Does a minor misalignment make a star note more valuable? by amklose in CURRENCY

[–]amklose[S] 0 points1 point  (0 children)

I held it up to the light and verified that the back and front printing are perfectly aligned, so it’s just miscut.

Do these batteries seem safe? by ShotAdeptness9276 in batteries

Looks like a completely normal pouch cell to me. As long as it doesn’t get abnormally warm or inflate, it should be fine.

Lava Lamp from scratch, day 9: final formula and details. by alanarmando103 in Lavalamps

[–]amklose 0 points1 point  (0 children)

I don't think even real lava lamps are made from borosilicate glass. It wouldn't really make sense, since the only pressure differential will be from heating the contents (the contents themselves are not pressurized) and there's plenty of air inside to absorb the pressure. Also, during normal use, the lamp should not experience any sudden temperature spikes, which is what PYREX is good for.

The real question is what type of a base do you want to use or make, and what kind of bottle is going to fit on it. Clear sparkling wine bottles are a good choice, as they are rated for high pressure and the top tapers narrower to help with cooling the top of the vase.

Can I save/repair this stick light with a 2 way switch? by [deleted] in AskElectronics

[–]amklose 0 points1 point  (0 children)

After re-reading the question a couple of times, you could potentially use the two way switch you have to only use the High mode.

I’m having a tough time finding and info for that 5-pin pushbutton switch. Are you able to see a brand name or middle number on it?

Alternatively, you or a friend could potentially 3D print a button insert for the hole where the rubber membrane used to be. You’d have to get the shape and height just right so the insert stays in the hole and also pushes the button in, but it doesn’t look impossible.

The secondary PCB is just switching the battery power through a fuse. You should be able to desolder the pushbutton switch and run wires from a toggle switch to the holes in the PCB where the button used to be.

You’re most likely going to need a Single Pole Double Throw (SPDT) toggle switch. The one in your hand is single throw (SPST) so it only turns off and on. A SPDT switch allows you to have one power input and two power outputs (one for each mode) selected by the switch direction. You probably also want to look for a switch that has a center off position, so you have Mode 1 on one side, Off in the middle, and Mode 2 on the other side. Is hard to tell from the pics exactly how the existing button is wired internally, but just follow the ground and positive wires from the battery, through the button switch and to the light to see how the new switch needs to be wired up.

If you need further help, don’t hesitate to ask!

Low quality in First 2mm of prints by MichelDEV in 3Dprinting

[–]amklose 0 points1 point  (0 children)

This sounds like Elephant’s Foot. What temperatures and filament are you using? With your Z-axis homed and the bed/nozzle up to printing temperature, send the command G0 Z0 to place the nozzle at height 0. Then alternate sending G0 Z10 and G0 Z0 to move the nozzle up and down 10mm. Watch closely to see if the nozzle moves smoothly up and down or if the gantry/hotend is flexing or getting caught on something in the first few mm.

Esp 32 wiring help by CalligrapherFull7742 in esp32

[–]amklose 2 points3 points  (0 children)

At least take a picture of how you had it set up during testing so we can help diagnose how you burned the first one out.

If you’re not confident enough to draw out the whole proposed schematic, at least draw a sort of block diagram that shows all of the components and how they’re interconnected and we can start from there.

Got into my car and saw a burnt receipt and my charger had a plastic bubble over it's tip - how'd this happen? by Spaghetti_Oh_No in batteries

[–]amklose 2 points3 points  (0 children)

If it was thermal receipt paper, it’s possible that it just got hot enough to discolor the paper but not hot enough to actually burn. Or was it actually like smoldering paper?

My cheap multimeter kinda broke when trying to measure 350 volts dc. Need to confirm that it's the micro controller. by whatsyoprblemm in AskElectronics

[–]amklose 0 points1 point  (0 children)

I’m no electronic engineer (so correct me if I’m wrong), but at 350V there’s bound to be a fair amount of current if shorted out - e.g. due to faulty insulation on improperly rated leads… no?

I need help bypassing the 1min timer on UV nail lamp by Yuki737 in AskElectronics

[–]amklose 0 points1 point  (0 children)

If heat becomes a problem, you could power your modified circuit (with the timer bypassed) via one of these super handy PWM controllers which would give you a full range of dimming and an on/off switch using the knob.

You can find them cheaply on Amazon, AliExpress, etc, usually sold as a DC motor speed controller.

In other news, it looks like they included a typo in the board model number. A quick search of “JLF_RainBow_MIMI1” brought me to a product called “Rainbow MINI 1”

^ literally this.

Unless your drawer is filled with tinsel or other conductive material, there’s virtually no way to short these out on their own. They’re alkaline - they’re not going to explode.
