PCB

A printed circuit board (PCB) mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes.

12V Lamp Flashing Circuit

“Here is a project that involves the electric side of your bike or car! we are building a 12V Bulb flashing circuit and I fully documented the necessary steps to achieve a working circuit for such purpose. You will not …

Joule Thief LED Tea Light Adapter

“Adapt your LED tea lights to run on “dead” batteries with this pretty holder! Earlier this year, I created a circuit board for the classic “Joule Thief” circuit, which allows you to run small projects off of nearly-dead batteries (including …

SMD Reflow Hot Plate

“A DIY temperature controlled Hot Plate for soldering SMD components. Story Over the years, electronic components have changed both in terms of size and also their footprint. More and more designs incorporate or solely use surface mount components (SMD) rather …

Temperature /Pressure meter using Arduino

“A small but effective sensor which can measure temperature and pressure and then mark those readings for weather forecasting. Today we are going to make a minimal pressure sensor integrated with temperature sensor. This pressure sensor is also able to …

USB PD Adapter

“The USB PD Adapter is a USB Power Delivery trigger and monitoring board that enables you to use almost any USB Type-C PD power supply to run your projects with different selectable voltages and high currents. Important values such as …

Wireless, Battery-Powered, Water Detector

“A water detector powered by a LiPO battery that transmits its status and notifications via MQTT to Home Assistant. About A while back my indoor air conditioner air handler’s condensation pipe clogged and caused a small flood. Thankfully we …

“In this interesting project we will see how to create a DIY(Do it Yourself) 7 segment. In this interesting project we will see how to create a DIY(Do it Yourself) 7 segment which is comparably larger than the …

DIY Non-Contact Tachometer (RPM Meter) With Arduino and IR Sensor

“A RPM meter is a simple device that is especially useful for example in a machining workshop to meassure the RPM of a machine’s spindle and thus determine the surface speed of a tool or workpiece. I decided to …

ESP8266 Programming Shield is Insane

“This is an amazing approach to program these small power microcontroller without spending a lot of money on development shields. I am using ESP8266 module in lots of projects. But always I have to use development board for that. ESP8266 …
