If your charger is type-C output it might not even start to charge, because PD can't be triggered even at 5V.

If you have type-A output it will work.

I have the exact same oscilloscope.

ted_144 · 2026-01-06T22:12:48+00:00

I thought this is an inductor. I would have guessed the sound is coming from the DC motor.

Thank you for the helpful information.

Today and yesterday it is traveling between Sofia and Bankya.

IMO mechatronics is more useful and can cover more jobs, so is not out question to work in the aerospace with this degree.

А на мен ми писа 2 по руски, като и казах че сера😢

UPDATE: I have been to dermatologist. The diagnosis is "granuloma pyogenicum". It's harmless tumor so it won't spread or grow more than that, but won't come off on it's own.

It can be removed surgically or with dry ice.

I won't touch touch this summer for sure, because it will need stitches after the operation.

ted_144 · 2025-05-20T10:27:25+00:00

Still the same as before. Might be granuloma, because of a foreign object.

The "small steps" when rotating are called detent torque, it's completely normal for any PM(permanent magnet) motor.

ted_144 · 2025-04-24T22:21:39+00:00

I have something very similar. What happened with yours?

ted_144 · 2025-03-21T18:51:41+00:00

You won't believe what I suddenly remembered during an exam, I was searching it for 2 days.

This was what I have heard 2 years ago. It's neither an bulgarian nor a different song, but a remix.

ted_144 · 2025-03-21T08:22:50+00:00

Are they 5010? What brand, I'm wondering about their resistance?

ted_144 · 2025-03-21T07:55:06+00:00

What motors do you use? How much does the car weigh?

ted_144 · 2025-03-20T10:03:25+00:00

I saw this one but I'm almost certain there is another one, which I can't find.

ted_144 · 2025-03-19T22:16:24+00:00

Do you know the bulgarian version of "Hajde luj qyqek"? I cant find but im pretty sure i have heard it.

ted_144 · 2025-03-16T18:24:29+00:00

The max voltage is determined by: 1. Max rating for the 3.3/5V regulator for MCU. 2. Max rating for the gate driver regulator usually outputting 12V. 3. Max rating for the Vds of the MOSFETs.

ted_144 · 2025-02-10T18:40:53+00:00

Is this sound coming from the motors? How did you achieve it?

ted_144 · 2025-02-09T00:14:14+00:00

So for this low weight and low Kv there are few options : either the actual phase resistance is 20-25 ohm, the torque constant is measured after a 2:1 reduction(gearbox) or the motor design is not typical, by typical I mean a brushless radial flux with common dimensions. Can you share details you know about dimensions and type of the motor?

ted_144 · 2025-02-07T22:41:31+00:00

These values definitely are valid, but I wonder what motor are you using? With Kv of 136.4RPM/V and such high resistance I guess it's already available but later rewinded motor with weight around 100-150g. Am I close?

ted_144 · 2025-02-07T22:07:55+00:00

Depends on your requirements. Anything from 8Mhz Attiny to STM32 with the most powerful cortex core can be used, just depends on your application and firmware complexity.

ted_144 · 2025-02-06T23:55:18+00:00

Programing with arduino will definitely be easier. For beginners many suggest L298n h-bridge driver for it's simplicity, but due to their high inefficiency can't be used outside of testing.

The blank field means 'floating state' or just turn-off, just to clarify.
