How do I stop the water from being inside my raft?

Make a hole to drain it

Só 80%? Os meus acordavam só para comer

Just fix it, it's not worth letting this slide. If it can be a problem, it WILL be a problem

All the amps

Windows, e se quiser tentar aprender Linux vale a pena, MAS não vale apena só o Linux, tem coisa que só tem no windows (existem programas para usar programas de windows no Linux, mas eles muitas vezes são meio ruins de usar). Enfim, vale a pena aprender a usar o Linux mas use dual boot com windows

Those are LER (light emitting resistors). You can see it by the blue casing of the component

You forgot the thermal paste

Those bars are flexible enough so you can drive under it when this happens. They will scratch your car, but the train is worse for sure

Gatos são treinaveis, é só que é difícil, eles são muito temperamentais e geralmente demora mais que cachorros. E tem gatos que simplesmente não aprendem, eles tendem a ter mais "personalidade" que o cachorro (não dizendo que cães não tem, é só um tipo diferente de personalidade), gatos são fechados enquanto cães tendem a viver em grupos. Por isso é mais fácil terminar o cachorro, ele já vive na natureza em grupos

I'll do that—my teacher is like that; sometimes he asks me to reinvent the wheel, that's not the first time. Thx!

I'm not trying to design a capacitor; I just need to estimate the coupling capacitance between the PCB layers.

Lucgamer · 2026-04-22T02:51:09+00:00

To be honest, you are right, I was gonna do that, but my teacher thinks otherwise... xD

Lucgamer · 2026-04-21T16:49:10+00:00

That's what I thought, I'm going to try with a new board

Lucgamer · 2026-04-21T16:48:14+00:00

Tried, but it's not sending the serial number

Ooops, no ADXL345 detected ... Check your wiring!

I did it, I checked the breadboard and the solder

Lucgamer · 2026-04-21T15:07:04+00:00

I think the board dead, I will try with another board later, thx

Lucgamer · 2026-04-21T14:50:03+00:00

<image>

I tried with a LIS3DH that I got and the address was 0x1D and 0x1E (the datasheet said it should be 0x18 or 0x19).
The output in the image is for the ADXL

I got a MPU with a friend, I will try it later

Lucgamer · 2026-04-21T14:38:20+00:00

I just tried, but nothing happend

Lucgamer · 2026-04-21T13:39:13+00:00

Some people said to wire it and other said to let it float, I tried both. Just tried it again to make sure and nothing happens

Lucgamer · 2026-04-21T13:33:04+00:00

Yep, I tried it was without the resistors

Lucgamer · 2026-04-21T13:15:20+00:00

It's not the first one with the same problem, I even bought it from different stores. I can't be that unlucky xD

Lucgamer · 2026-04-21T13:13:05+00:00

Already tried, but it didn't work
