In this project, I will go through the process of designing and making a flight controller board from scratch for a micro-quadcopter. This board will be based on the ATMega328 microcontroller and will be used to control four coreless DC motors. The whole PCB making process from designing of the schematic to [**custom circuit board**] is done using EasyEDA. If you are interested in the circuit p...

Since a lot of our followers asked for a tutorial to guide them to make a basic Robot we decided to provide this instructable that describe a step by step making of **LINE FOLLOWER Robot**, so you will find all the necessary software and hardware parts to make your own Robot following these steps
Note: In this project the main part was made usi...
This is my atmega8 (and ATmega328 compatible) development board.
As it has the uart connector, you can program it in the arduino ide, if you are into that. You just need to download the bootloader through isp programming.
(I personally prefer to do it the expert way)
I added some connectors according to what I usually use:
I2C (also pull ups)
SPI (with an extra pin for devices such as nrf24,...
Hello friends, on this occasion I will share tips on how to order SMT Assembly at [JLCPCB](JLCPCB).
SMT Assembly service, namely SMD component soldering services, SMD stands for Surface Mount Device, which is a very small and legless component like a DIP / Throughhole component. Because the component is very small in size, we often have trouble soldering the PCB, even those who are still unfamili...
I made this schematic for the Arduino Nano 3.2 to be as close as possible to the official schematic found [here](https://www.arduino.cc/en/uploads/Main/Arduino_Nano-Rev3.2-SCH.pdf). I chose similar components as on the official Nano. This does mean the schematic is a bit weird, as the resistors, for example, are merged into resistor arrays, meaning I had to make some jumps to the arrays. The PCB d...
Using a 555 timer and a mosfet to control the speed of a DC motor with a potentiometer.

1. Remove components on single-side printed circuit boards [jlcpcb](jlcpcb.com/m): toothbrush method, screen method, needle method, tin suction device, pneumatic suction gun, and other methods can be used. Most of the simple methods of disassembly of electronic components are only suitable for single-side boards, which has a poor effect on double panel and multi-layer board.
2. Remove components...
# **What is PCB?** #
[PCB](jlcpcb.com/m) also is known as the Printed Circuit Board, is an important electronic component, the supporting body of electronic components, and the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.
[JLCPCB](jlcpcb.com/m) is the first and the largest professional PCB prototype...
For electronic engineers, the manufacture of [the circuit board](jlcpcb.com/m) is a necessary step, but the # shortcut of the circuit board # is a much common problem during the manufacture of the circuit board.
A shortcut for the [Printed Circuit board](jlcpcb.com/m) may cause components to burn out and the system to fail, so we must pay attention to it.
Today we would like to analyze the main r...
PCB now is everywhere almost all electronic products show in our life need [PCB Board](jlcpcb.com/m), while nothing will last in good condition forever, when the PCB board get problems, we have to repair it.
Today we will discuss **[how to repair the PCB Board](jlcpcb.com/m)**.
Almost all [PCB repair](jlcpcb.com/m) without drawing materials, so a lot of people are skeptical of circuit board main...
In this project, we will make a **4-Channel Relay Driver Module Circuit** for relay based applications. In this circuit, we have designed an isolated PCB for 4 relays. By using this **Relay Board**, we can operate 4 AC appliances at a time. We have put a three pin screw terminal blocks (NC, Nuteral, NO) for connecting appliances. Below are the circuit diagram and PCB layout designs of the relay dr...
Cool Nixie Tube Clock, design works out of the box. All parts (execpt for the tubes) can be ordered from LCSC, if you have any questions feel free to contact me via easyeda messages.
It is recommended to put the nixie tubes on special nixie tube pins, these can be found on ebay.
All design files are available from here:
