Manual CNC control

I've been working with Anthony from Alpha Mods channel to make the control of a CNC machine but using buttons and potentiometers for a manual control. The setup could set the speed, move 2 axis and print the distance on the LCD. Check more here...
Homemade, vintage Nixie tubes clock

I've made my own design of "nixie tubes" which actually are some 7 segment displays. Using some filament LEDs I was able to give this project a nixie tube loog, inside of a plastic bottle and create a real tiem clock with 4 of these displays. Check more here...
Servo gimbal - with Arduino

I've tried to make a servo based gimbal. I've used servos since those have good torque and I wanted a big gimbal good for bid DSLR cameras. But the final project wasn't that good. Check more here...
ATtiny based simple radio controller

In this tutorial we will make the most simple radio controller there is. Using an ATtiny and a 433MHz radio module. The entire project costs around 3 dollars. Check more here...
Gyro radio controller

We've seen a lot of controllers on this channel. But this one is a bit different. We now use a Gyro control for 2 analog channels. Also, the radio mdoule is a HC12. Check more here...

We read the serial data from the Perismatic software via USB connection. The arduino generates the data for the LED strip and send it to the Din pin. The LEDs will change their color coresponding to the image on your screen.
Arduino power logger + Voltage and current

We read the current using a shunt resistor and basic ohm law. We amplify the voltage drop with and OPAMP and read that with an Arduino. Finally, we use an i2c display and print current, voltage, power and energy.
Arduino step motor slider - 3D printed

I've designed all the 3D parts for a camera slider. Using a step motor we can preciselly control the speed and direction of the slider. I've made a 3D case with a rotary encoded menu adn LCD inside for control.
