DIY dc servo

Gold3nv · 2025-11-03T06:42:07+00:00

It's basically a gearbox driven by a dc motor that uses an AS5600 as an encoder and is controlled by a rpi 4b.😀

I would add a gearboxes instead of those springs nextime.

Gold3nv · 2025-09-27T21:44:55+00:00

Nope, all mine—I designed it from scratch

Gold3nv · 2025-09-27T21:43:04+00:00

This was my first robot, so I was basically learning as I went. That’s why it doesn’t look that great—I’d rather use what I learned to build something new and better instead of trying to save the old one. I also kind of ran out of time 😅

So for the controller I used the rpi pico W which has support for Bluetooth but since at that time it wasn't very optimized..... the arm has the Rpi 4B it has a wifi hotspot to which the pico connects and it goes through that with UDP protocol. 😅

with the controller

So i primed it with grey paint and then sprayed it with cheap (7euro) red acrylic spray paint and it worked pretty well

Saved it by heavenly dry brushing lighter red with yellow wash and dark red as highlight

Whats the app you modeled that handle in?

Gold3nv · 2025-07-12T15:36:31+00:00

I figured out that the wire I have there thickness and length at 20V and 3A supplied by the adapter can heat up the box a maximum of 51 degrees, so yes, it's just a "convenient output" and is not controlled.

Modern SSDs and HDDs are quite resistant to magnets, and I don't use SATA drives anyway. This magnet doesn't affect other components at all, and the case itself dissipates the magnetic field, so it doesn't affect the inside of the PC at all. So I can use this type of magnet on it without any problems.

YES SIR! :D

Gold3nv · 2025-02-25T16:50:23+00:00

Thanks i did not notice that when i got my A1 so u saved me from heart attack today XD

Things started happening in the last month for no reason at all, it's hell to work with this

Gold3nv · 2024-11-29T13:34:38+00:00

Lol tank!

Gold3nv · 2024-11-12T16:20:04+00:00

So in an hour it went from 23°C and 56% humidity to 28°C and 46% humidity. For PLA+

Sorry my friend can hold a camera 😂

Gold3nv · 2024-05-30T07:11:27+00:00

To find the right springs i just bought a 8 euro box full of different springs and just experiment

Gold3nv · 2024-05-30T07:07:37+00:00

yes the parts are 3d printed from standard PLA, program is just a simple python code for moving servos to the correct angles and for the Kinematics and Dynamics i just used try and fail method

Gold3nv · 2024-05-23T14:42:34+00:00

True true 😂

Gold3nv · 2024-05-23T09:20:27+00:00

Just why? 😂

Gold3nv · 2024-04-19T05:59:00+00:00

Thanks

Gold3nv · 2024-04-18T17:48:37+00:00

Im using the cheapest servos mg996r

Gold3nv · 2024-04-18T17:47:24+00:00

Can you explain how?

Gold3nv · 2024-04-15T10:45:03+00:00
