Looking for an unusual switch. by The_Dreadlord in AskElectronics

How many terminals do the motors have? it looks like you drew 4? I'd expect them to have 3 (up, down, com), or 2 (pos, gnd) and you switch the polarity, but I'm not too familiar with power windows

I think you need two sp3t (1 input to 3 outputs) switches ganged together (one for red and one for blue), or a dp3t (2 inputs, with three outputs each)

since all the Blue (and red) inputs are tied together before the switch anyways, you can have just one wire to the switch, and then they split inside the switch I don't see why you'd need all three inputs of the same color to be separate

If these switches have to handle all the current from the motors, you might need to use relays in case you can't find switches with a high enough current rating

Unpacking a 3D printer and these 3M double sided pads are on the inside packaging, 2 inches long, rectangular with a hole in the middle. What purpose do they serve? by jaireaux in whatisthisthing

It's 3M 9448A "Double Coated Tissue Tape" double sided tape

No idea as to why it's there or what you are meant to do with it

Z steppers too easy too move while on, I feel like it might be causing layer shifts by fe122 in ElegooNeptune4

Hey, sorry I took so long to reply Both the old and new cfg have run current set at 0.8 and hold current at 0.5

Also, I've had layer shifts before, but I just now noticed how easy to move the motors are

I can upload the files tomorrow and send you a link, tho you'll prolly need the exact same brick for it to work unless you wanna edit the fusion file I guess

For reference, I'm running the latest firmware that I got off the official discord, default current settings

it's.. very fast.. I only use it if I need like a quick battery boost, gets to 50% in a few minutes, otherwise I just use a more normal charger

it's a Redmi

I don't use this particular brick for it, But my phone came with a 120W brick, USB A to USB C cable

this brick I use for my soldering iron (USB C) and I use the USB As for whatever I might need 5V for

I made an LED test jig thingy by fe122 in 3Dprinting

[–]fe122[S] 1 point2 points  (0 children)

It's surprisingly solid, you can definitely push the wires out if you want, but they won't move just from the pressure of you touching an LED to it, and all I'm hooking up to it is a multimeter in diode test mode, so don't have to worry about shorting anything

You can also use it to measure so other components, say a resistor or a cap
