Presented here is a shortcut to build your own bluetooth stereo audio adapter for listening ‘wire-free’ stereo music on the go! The one and only building block of this project is a Chinese bluetooth audio […]
This article shows how to use an Arduino microcontroller (Uno/Nano) and an organic light emitting diode (OLED) display for making a basic digital voltmeter (DVM). The given design configuration makes it useful for measuring DC […]
To use a capacitor in your electronic projects, understanding capacitor colour code is required. For identifying the capacitor values and tolerances international colour coding scheme (electronic colour coding) was introduced. Every capacitor has colors or […]
A few readers demanded to see one simple circuit of a rechargeable power white LED torch that can be charged through a regular electrical outlet. Alright, here’s the circuit diagram of a simple yet useful […]
I stumbled across this Chinese solar wall light last week in Amazon while searching for automatic LED street lights. Admittedly it’s not a good fit as a powerful street light but reasonably good for pathway […]
If you are an active cyclist you must become more aware of safety and in particular your visibility to other riders, especially in winter and monsoon seasons. One drawback of your (pleasantly cheap) dynamo lighting […]
Here’s a little audio amplifier project you can build from inexpensive and easily available parts. You can use this monaural audio amplifier even in any robotic project where you need to amplify audio signals. The […]
Lithium-ion (Li-ion) battery have cemented its position as the primary power source for portable electronics. One of the key benefits of a lithium-ion battery is that it have high energy density without being too bulky. […]
Most modern electronic circuits and devices consist of different types of capacitors. Electronic newbies, experienced engineers find that these components are quite interesting due to their applications. In radio technology, Capacitors can be categorised into […]
When a number of resistors are connected in such a way that the end of first resistor is connected to beginning of second resistor and the end of second one to third resistor and so […]
