Portable Soldering Iron V3.0
Finally, the board works perfect. So I could make a 3D design for the case and this is a final product that could end up on Kickstarter. See here how to build one. See schematic, layout, components and final code firmware V3.3
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...
Atmega8 bootloader burn
I’ll show you how to use the ATMEGA8 with the Arduino IDE just as we do with the Arduino UNO chip. We will burn an 8MHz bootloader to it so we would be able to upload sketches later.
Portable solderintg iron V2.0
Since the last version, I've made some improvements for the soldering iron board. Now it uses the T12 tip and gives much better results. In this project I show you how I've made the board, how to solder everything, program the board and test it.
Fingerprint sensor door lock with blackbox
We learn how to use the fingerprint sensor and also how to add new IDs. Then we use that to make a door lock. As a black box, we use a real time clock to get the real tiome and an SD card to writhe the logs of what happened to the door lock in each moment.
Electronoobs Watch
Learn how to use the ATmega328p-AU chip with internal 8MHz bootloader. Also how to use low consumption mode for the Arduino and me the watch last more hours...
220V AC PID temperature control
We use a TRIAC to control AC 220V voltage applied to an AC heater. Witha thermocouple we read the temperature and create the PID control.
Brushed motors drone (very cheap)
This is the version V2.2 for the brushed motors drone. It finally flies. Check the tutorial for all the steps.
Homemade ultrasonic distance sensor
We learn with more details how these modules work. Then we build our own applying the theory. See more here...
Homemade IR remote
An arduino, some IR LEDs, a phototransistor and we've got ourselves a IR remote. See more here...
IR remote with Arduino VS1838
Let's see how to use the ATMega328p chip, which is the microcontroller that the Arduino UNO board uses. Once we know the bare minimum configuration, we could add this controlleer on any board that we create.
Thermocouple read example
Use the MAX6675 connected with SPI to the Arduino and read real temperature values form a k-type thermocouple. Easy and fast example.
DIY portable soldering Iron
Looks awesome right? After I've seen the TS100 soldering iron, I've started making my own portable soldering iron. I've made the PCB, add all components such as the heater, the thermocouple, the MAX6675 IC, a microcontroller and an OLED screed.
Arduino 3D scanner
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 ambilight with WS2812 LED strip
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.
ARDUINO RFID DOOR LOCK
Read an ID tag with an RFID module and Arduino. Detect if the ID is correct and open a servo motor. Using a master card, add new IDs. Error message if ID is incorrect.
DIY RADIO CONTROLLER ARDUINO+NRF24
Build a radio transmitter with 5 analog channels and 2 digital. Use the power amplified antenna and send 7 bytes of data. Receive the signal and create a PWM output foe each channel with range 1000-2000us.
PID TEMPERATURE ARDUINO CONTROLLER
Full Temperature PID controll with Arduino. Closed loop. See all the schematics, codes and examples here.
