Dimmable USB-C powered LED light for gigs
Just a prototype here, need to 3d print a case and make it more abuse-proof. Ended up not even needing an Arduino and just using a 555 timer :D
Arduino portable soldering station
Heyyy, i made this soldering station to be compatible either with drill batteries or laptop psu (everything 15-24v). The temperature can be set with the 2 buttons and by pressing them simultaneously it displays the percentage of the baterry and when the battery is low it starts blinking. There's also a protection from broken cable or heater problem so it won't overheat. The temperature can be precisely calibrated via the potentiometer. I used lm358 but there're better options out there with lowe...

pcb design schmatic
Are you looking for a precisely engineered PCB enclosure for your electronics project? I specialize in custom 3D design and enclosure modeling tailored for PCBs, IoT devices, development boards, keyboards, and more. Using SolidWorks, Fusion 360, and Blender, I provide accurate and ready-to-print CAD designs for 3D printing, CNC, or injection molding.
Whether you're building a prototype or need a sleek product-ready case, I ensure proper component spacing, ventilation, mounting holes, and aesthetic appeal. From KiCAD/Altium PCB layouts to final 3D renders, I’ve got you covered!...

QTRMuxes Library
🚀 I just published an Arduino library called QTRMuxes!
It lets you read multiple QTR sensors through one or more CD74HC4067 multiplexers. Super useful for line-followers or sensor-heavy robots.
✅ Works with the official Pololu QTRSensors library....
Breadboard controller held together with tape
It works on games - I’ve tried it in counter strikes - i dont have a 3d printer or anything but scissors cello tape and cardboard are basically the same thing anyway

We Built a Rocket – We Need a Programmer! (Arduino nano)
Hey everyone! 👋
I’m French, and with some friends, we’re building an amateur model rocket. We’ve designed and assembled our own PCB for the onboard computer, which runs on an Arduino Nano.
The hardware part is done, but we’re having trouble with the programming. We’re looking for someone to join our team and help us with the Arduino code side of the project.

I created a smart motion detector alarm that sends SMS alerts — here's a free step-by-step guide
I recently built a DIY motion detector alarm using an Arduino Uno, PIR sensor, and SIM800L module — it sends an SMS whenever motion is detected. Super useful for things like home security or monitoring your mailbox.
I’ve had a lot of people asking how I made it, so I put together a beginner-friendly 37-page guide.
Inside, you’ll find:...

no idea why it’s doing this glitchy boot but progress so far, goal is to get it a pcb
Imu6050 with 3D visual
Learning the MPU6050 3D preview WebSocket serial communication, it can be developed into an interactive game or something similar.
By the way, this kit is really great and complete if you want to learn IoT/embedded/ESP32....
