In this section you will learn and build simple electronic circuits projects. You will make interesting analog electronic circuits useful in daily life. Moreover, you will know electronic circuit design using circuit elements.
The circuits include home made electronic circuits, hobbyist circuits and prototypes.
Like the ducklings followed their mother around the pond, certain electronics hobbyists are still going along with pre-wired China modules. Certainly it’s not a good habit because by taking shortcuts (even for simple tasks) they’re […]
Here’s one simple circuit idea of a 4-digit 7-segment light emitting diode display module which can be driven by many microprocessors and development boards. I have been using it with my Arduino microcontrollers since getting […]
Let me have my say – it’s my habit to do things over again. Not a mere repeat of anything that fitted well, but wishing to try potential betterments at slightly different angles. Confused? Sorry, […]
Do you like the idea of high-voltage electronic sparking devices, but don’t have the time or patience to learn the complex theory? Here’s a simple tutorial that can help you to make many high-voltage projects […]
USB LED Flashlight presented here is a simple do-it-yourself rechargeable flashlight with built in rechargeable cell, cell charger, white light source, and a standard usb interface for overnight charging. Since the design is based on […]
Late month I’d got an order from my neighboring client to build a pulse width modulation to dc voltage converter module that’s compatible with common microcontrollers and PLCs. Since it’s a fussy time for me […]
May it be a surprising title – Loafer’s LED Wick! Let it be, the article is nothing but the design idea of a little LED light based on Joule-Thief concept. It’s true that by a […]
It’s damn sure, there’s plenty of old optical and magnetic disc drives (CD/DVD/HDD) in every electronics/hardware hobbyist’s junk box. Sadly it’s known to few people that such disc drives are rich and cheap sources of […]
Optical smoke alarms, also known as photo-electric smoke alarms, are particularly useful in bedrooms, lounges, hallways, and in other areas where we can otherwise expect false alarms from the common ionization smoke alarms. An optical […]
Water Pressure Sensor is not a familiar everyday sensor for most electronics hobbyists and makers, so here’s an introductory tutorial on a popular water pressure sensor – the DFRobot Gravity: Analog Water Pressure Sensor. In […]
