Hello everyone, there’s battlebot event coming in my region and i would like to compete in it, thus i decided to collect some useful information.
I want to build robot with vertical/horizontal spinner weapon under 1.5kg, can you share your builds and some information about them? What components did you use? Explain your weapon system…
For now im planning to use n20 motors to drive wheels and 2700kv brushless outrunner to spin the weapon, what bldc driver should i use?

Hello everyone, this weekend i decided to build small self balancing robot for the first time. Everything works fine but im having a hard time balancing it, im using pid controller. Any suggestions how to make process easier (currently i have to tweak pid values manually and upload new code every time)? Any suggestions?

Hello everyone!
I’m a 19-year-old EE student, and I’ve been using a 3D printer for over three years. Now I want to step up my skills and get into CNC machining.
Recently I came across the Makera Z1 desktop CNC. On paper, it seems like a solid machine for a beginner, but I’d love to hear from people who have actually used it.
Do you think it’s a worthwhile investment? My goal isn’t to start a business—I mainly want to learn CNC, CAM, and machining while building small projects from wood, aluminum, brass, and other soft materials.
I have a few questions:
How has it held up over time?
What are its biggest strengths and weaknesses?
Is it worth the price, or are there better options in the same price range?
If you had around a $1,000–$1,500 budget, would you still choose the Z1?
I’d really appreciate any advice or experiences. Thanks!

Hello guys, recently i decided to build my first rc plane. Its similar to cessna design.
70cm fuselage
90cm wingspan

My question is how do i handle flaps.
I want to use just 4 servos so im thinking to make elevators on the back and pair of ailerons on main wing. Will those 4 flaps let me do basic maneuvers?
Like gain altitude, roll, land.

Also should i add rudder?

After many variations my controller is finished.

Based on CyberBrick remote kit.
Easy assembly with pdf guide

You can check it out on makerworld.

After several weeks of designing and testing, I finally finished a pistol-grip style controller for CyberBrick RC cars.

Features

Steering wheel control
Trigger-style throttle
LED control button
Customizable joystick
Customizable 3-position switch
Compatible with the original CyberBrick Remote Control Kit (ZK007)
No additional tools required for assembly
Can be assembled in about 15 steps

Development Process

This project went through roughly 10 design iterations before reaching its current form. Each version helped improve ergonomics, assembly, and compatibility. While I’m happy with the result, there are still several areas that could be optimized in future updates.
The model includes a PDF assembly guide and is designed specifically for the CyberBrick Remote Kit.
I’d love to hear your feedback, suggestions, or ideas for future improvements. If you find the project useful, please consider liking, sharing, and downloading the model—it really helps more makers discover it and motivates me to continue developing CyberBrick accessories.

Thanks for checking it out!

P.S i will leave the link in comments for free download

Hey guys so i just made new cyberbrick model and created this configuration but when i try to upload json file on makerworld it shows error: “Invalid JSON file, please check the file format and try again.”

Any ideas how to fix it?

Hey guys, when i keep my printer idle it makes this noises, is that ok? Also do you guys turn printer off when not in use or do you keep it on?
