Creating a Printed Circuit Board From a Diagram

Converting a circuit diagram to a Printed Circuit Board (PCB) could prove to be a challenging task. But luckily with technology today it is fairly simple to complete this task, so there's no need to be stressed out. We will be doing an easy one for today. It is called...

Getting Started with NodeMCU with ESP8266 part 2

In this tutorial we will control electrical devices like fans, lights, etc., using esp8266 from a web browser.  The Arduino sketch below shows how you can add html code (web page code) to to the NodeMcu board so it will give you a web page when connecting to it. The...

Getting Started with NodeMCU with ESP8266 part 1

The first thing you need to know is that the ESP8266 WiFi chip is much more than just a WiFi chip. It also includes it's own microprocessor, 16 input/output pins, 64 KiB of instruction RAM and 96 KiB of data RAM. The ESP8266 chip can me run as a serial device from an...

Introducing the XLR8 FPGA-based Arduino Uno Clone

XLR8(Accelerate) that has the same footprint as an Arduino Uno, but that runs like an Arduino Uno on steroids Regular Arduino Uno By default, the XLR8 behaves just like an Arduino, right down to its timing and 16 MHz clock. However, the XLR8's clock frequency can be...

Using a Washer To Steady Joints While Soldering

If you have “helping hands,” clamping wire leads against a washer, as shown, stabilizes the whole setup dramatically by connecting the two arms with a rigid member, so you can bear down a bit more with the iron without pushing things out of alignment. But the hole in...

Joining wires, The NASA way

Some commenters on my post about using a washer as a soldering aid noticed my sloppy splicing technique and were kind enough to educate me about the so-called “Western Union splice,” aka the “Lineman’s splice,” which is the preferred method for twisting solid-core...

Pulling Larger Loads

If you are anything like me, this simply is not enough! No, you want to use this in your next Arduino project. But the Arduino only supplies 5V and even if its a large 5V device the maximum current per I/O pin is 40mA, a normal red LED is already 20mA, so you can see...
