Recently, I came across the RDA5807 module which is an FM Radio Tuner in a very tiny package. It is very cheap and uses I2C protocol for communication which means that only two wires will be required to talk to the IC. Less wiring!

My mom used to listen to the radio every day while cooking food before the radio died. I wanted to surprise her with a radio which I built myself. In this Instructables, I will show you how I interfaced RDA5807 IC with an Arduino. To make it look good, I designed an enclosure and 3D printed it. I'm new to 3D designing so it will be a simple design. No fancy stuff.

In this tutorial we will merge all the parts seen in these past tutorials here. In those tutorials we have seen how to measure resistance, current, indcutnace and capacitance. Measure voltage is very easy. In this tutorial we make a 5 in 1 multimeter based on an Arduino, an ADC module and an LC tank circuit. The case is 3D printed. You have the schematic, code and all you need to amke this project .

Perfect for drilling pen blanks or any small pieces vertically in your drill press, easy to build and a must have drill press jig. I always suggest watching the build video so that you have a better understanding of the project. For this project I needed one 3/4 of an inch board, 3 inches wide by 3 feet long. Going through my scraps I found a board I could use for this project, and starting with my table saw by ripped the board down to the width I needed. With my now 3 inch wide board, I needed to cut it to the right length. For this project I needed two pieces that measure 16 inches long, to achieve this I used my miter saw.

I've started a new project. I want to make my own homemade electric longboard with a powerfull Brushless motor. The first idea was to use two motors, but I had not enough space between the wheels of my longboard. In this tutorial we will see how to mount everything together, make a test and give the final results. Make sure you watch the tutorial on how I've made my homemade 6S battery pack in order to finish this tutorial.

A few weeks ago I've made this radio controller based on Arduino and the NRF24 radio module. Now we can see how to use it. We start with something easy. Servos are controlled with PWM signal. What we do is receive the radio signal, crewte PWM signals and control the servo turret. We also heat some nichrome wire and fire up some firework rockets. The design is 3D printed and uses some FUTABA servo motors. So, let's see.

Today’s project is not going to be based on evive. Today, we’re going to make yet another smartphone-controlled robot but this time using ESP32. It can move forward, back, right, left, and doesn’t need Bluetooth! We’re to program it in PictoBlox, our graphical programming software with advanced interaction capabilities and control it using Dabble, our smart project interaction and controller app.

You can download PictoBlox from HERE and get Dabble on Google Play.

Ready to make the robot?

Let’s begin!

I've been trying to make a good ESC for years. My first prototype 3 years ago was working "good". It was very big and the BEMF was not that good. It could reach decent speeds and you ahve that tutorial here on this page. Now, with my final version I have all taht I wanted. High speed, good BEMF detection and that means good torque, PWM control of the speed and small size. The board is programed in Arduino.

This, is version 2 of my very powerful coilgun. As you can see, is huge and it has quite some power and works with high voltage, so please, I can’t stress this enough. Never touch the high voltage parts, stay insulated, use proper tools and if you don’t know what you’re doing, don’t try this project, just watch the video for learning purposes. That being said, in this video I will show you the improvements from the previous version, I will rectify a small error I’ve told you in the previous video, I will show you the schematic, we design the new PCB, we check the part list and assemble the board. Finally, we test it and I also want to design a 3D case for it so it would look better than before. So guys, stay safe and protected and let’s get started.

For a while I’ve been watching PET bottles filament maker projects on YouTube. There are a lot of them, and I have to say, it is a very interesting project and I wanted to make one as well. So, following the same steps and ideas, I’ve made the design, made a schematic for a PCB, 3D printed some parts, made some tests and slowly made my own bottle to filament machine. Right now is not perfect, but at least, does it work? Well, check the post till the end to find out. I’ve made a PCB to go with this project and order it from PCBWAY, and basically, together with an Arduino, it should control the heating block temperature, the feeding speed, maybe a fan, it could also have a display and a control encoder and so on. So guys, let’s see how to make a bottle to filament maker and then try to print something with that filament. So, let’s get started.
