“Today we will learn how to make a buck converter using simple tools. we will make 5volt + 12volt Buck 3A If you understand the principle of the work you can make a buck converter with any voltage you want. Let …
“In this instructable I will show you how I made an electronic “decision maker” with the 4046 - phase-locked loop. What does that mean you ask? Well it’s basically a coin flipper. You press the button to start the oscillation …
“After many hours of work I’m very happy to finally publish all the sources for the ESP8266 PlaneSpotter project. It is not yet really in a V1.0.0 state but I’m sure with the help of the …
“FMBerry is a piece of software that allows you to transmit FM radio with your Raspberry Pi. It uses the Sony-Ericsson MMR-70 transmitter, which was originally intended for use with Sonys Walkman cellphones from early 2000s. You can get …
“This is a VHDL version of Amstrad CPC 6128 running on FPGA starter-kit NEXYS2 500k-gates from Digilent. A starter-kit is a board made for learning FPGA, so it is a standard FPGA development board. Please refer to [MiST-board CoreDocAmstrad] for …
“This is the toughest project for me among all of my previous builds and also consumes my lot of money and time, but the end result brings a huge smile on my face when I saw the complete build. I …
“Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents.Tesla’s original circuits as well as most modern coils use a simple spark gap to excite oscillations in …
“A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by …
“What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with interesting circuitry and unusual transistors. The …
“It’s amazing how quickly you can put together an IoT protect using a NodeMCU and a Blynk app. On this tutorial we will learn about a great, reliable and easy to use digital temperature sensor, the DS18B20. Also as …
