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.
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. […]
The RGB LED module shown in the above image is a very popular generic RGB LED module available in the market. There are mainly two variants of this module having common-cathode (CC) and common-anode (CA) […]
Every electronics hobbyist’s lab, or green energy lover’s home, needs an outdoor light powered by solar. If you’re one of them you should probably consider building this super simple mini solar street light for you! […]
This is a simple design guide for making your own really nice lighting for your home, office, shop, lab, etc. by using the common and inexpensive LED strips available in various colors. The intent is […]
Circuit of the Universal 1W standby LED Light introduced here is more self-contained and more flexible than many of the early designs. The circuit consists of a small Lithium-Ion (Li-Ion) battery, simple Li-Ion battery charger, […]
Quadrature Encoder is a familiar everyday sensor in robotics world. A quadrature encoder is a handy rotary encoder that let you know the speed and direction of a rotating shaft or linear motion. Let’s start […]
So I have this Tiny Chirp, when you power it up, an indicator wakes up and it does a sequence of wonderful chirps! First, you need one active piezo-buzzer (i.e. the type with a built-in […]
