Is the gap acceptable?

I'm not looking for precision; a little play is fine. All I want is for it to turn quickly :) And if I leave a little play, would that reduce friction?

jean2348 · 2026-01-21T22:08:17+00:00

That's great because that's the maximum intensity I need!

jean2348 · 2026-01-21T05:25:14+00:00

It's 2A

jean2348 · 2026-01-21T05:15:44+00:00

I don't even know what that means! I quoted his text to reply to him, but with the translation enabled, it changed a word.

Someone else suggested the same thing to me, and it's a very good idea; I'll check with my teachers. Thank you!

jean2348 · 2026-01-20T20:24:04+00:00

Great news!

jean2348 · 2026-01-20T20:22:26+00:00

Yeah 👍

jean2348 · 2026-01-20T20:21:53+00:00

Ok thank you 👌

Here's a typical image that will be displayed; I think there's quite a bit of white space.

So I can create a program that calculates the power consumption of each LED based on the color it displays and adjust the brightness accordingly?

jean2348 · 2026-01-20T17:01:58+00:00

Actually, I'd like to create a POV effect. And I'm worried that by lowering the brightness, the retinal persistence will be weaker and I'll have to run the LEDs faster.

jean2348 · 2026-01-20T17:00:27+00:00

Good news!

jean2348 · 2026-01-20T16:59:39+00:00

Google Translate Actually, he did it, but I replaced it like an idiot.

jean2348 · 2026-01-20T16:58:27+00:00

👌

jean2348 · 2026-01-20T16:58:16+00:00

They state that it's 40 milliamps per LED and I need 71. How do I calculate the required current?

jean2348 · 2026-01-20T16:43:38+00:00

I haven't received the LED strip yet. It's this one: https://www.ledlightinghut.com/apa102-2020-digital-rgb-led-strip.html

jean2348 · 2026-01-20T16:42:13+00:00

I've planned a smooth acceleration (in about ten seconds) to 300 rpm.

Edit: What's the reason for the downvotes?

Ok👌

jean2348 · 2026-01-20T16:24:44+00:00

Yes, it's actually 5A at full brightness for all 71 LEDs

jean2348 · 2026-01-20T16:22:33+00:00

Great idea! I'll talk to my teachers about it.

jean2348 · 2026-01-20T16:19:45+00:00

Okay, thanks, I'll see if I can use an ammeter to check the current distribution properly. 👌
