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.
Perhaps, the most ideal rechargeable battery chemistry for industrial electronics today is the LiFePO4 (lithium iron phosphate) battery. This newer type of lithium solution is inherently non-combustible and best known for its strong safety profile […]
Lady Beetle LED is nothing but a little automatic model toy light, may be a nice Xmas gift for your loved companion. Here’s its tried and tested circuit diagram: As you can see, the circuit […]
This is another revision of my USB to RS485 Converter circuitry which performs the USB (Universal Serial Bus) to two wire RS485 (two-wire half-duplex) and vice versa. This time the design focus is much more […]
Little LED Night Marker introduced here is a simple circuit based on the common and cheap dual-operational amplifier LM358. The night marker is in fact a safety device designed to mount near obstructions in unilluminated […]
Camper Inverter introduced here is nothing but the minimal design of a compact dc-ac power inverter built around a couple of less expensive electronic components. This little device can serve as a portable source of […]
Taser™ is a weapon that fires wires to deliver a temporarily paralyzing electric shock used in many countries and by law enforcement agents. Certainly my intention is not to share the circuit diagram of a […]
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 […]
