LiFePO4 Battery Charger

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

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 […]

Little LED Night Marker (v1)

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

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 […]

Nano Taser

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 […]

Light Intensity to Frequency Converter Module

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 […]

DC Voltage Booster/Multiplier

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 […]
