Simple Digital Timer Circuit with 2 Digit Display
This simple digital timer circuit can be used to obtain timing output through selectable ranges, which can be set from 0 to 99 second, with 1 second interval, 0 to 990 seconds with 10 second interval, and 0 to 99 minutes with 1 minute interval. All these timing outputs can be visualized and tracked through […]
High Voltage, High Current DC Regulator Circuit
We all are pretty familiar with the 78XX voltage regulator ICs or the adjustable types such as LM317, LM338 etc. Though these regulators are outstanding with their specified functioning and reliability, these regulators have one big disadvantage…. they won’t control anything above 35V. Circuit Operation The circuit presented in the following article introduces a DC […]
Lipo Battery Balance Charger for Charging of Series Connected Lipo Cells
In this post I have explained a relatively easy lipo battery balance charger circuit which is designed to continuously scan and charge the connected cells of the battery. The idea was requested by Mr. Schindler and Mr. Emil Jan Thomas Baticulon. Charging 6 Li-Po Packs The concepts are very well written, concise and clear. Thank […]
Medical Store LED Cross Sign Circuit [Plus Sign]
In this post I have explained how to make an interesting yet simple running LED cross sign or plus sign module for displaying in front of medical stores. Nowadays, it is very common to witness illuminated flashing, chasing LED cross signs in front of medical stores, which work like an advertisement board for attracting the […]
3 Watt, 5 Watt LED DC to DC Constant Current Driver Circuit
The following article provides a simple yet very decent solution for driving powerful LEDs rated at 3 watt or 5 watt. Circuit Objective These 3 watt 5 watt and similar high watt LEDs are able to produce highly intense and powerful light outputs, however these are extremely vulnerable too with their operating parameter. I have […]
