In this post I have explained the construction details of a triac based push-button dimmer circuit which can be used for controlling incandescent, and fluorescent lamp brightness through push-button pressing. Another feature of this dimmer is its memory, which retains the brightness level even during power outages, and provides the same lamp intensity after power […]

IC 555 Automatic Emergency Light Circuit
The discussed 2 simple IC 555 based emergency lamp system employs just a single IC 555 and yet is able to switch more than 20 LEDs directly, it will illuminate the LEDs only during the absence of mains power and ambient light. 1) Using IC 555 as a Comparator The proposed circuit is not only […]
Illuminated Crosswalk Safety Light Circuit
In this article I have explained a simple illuminated crosswalk safety light circuit for ensuring a safe walking passage for the user amidst heavy traffic. The idea was requested by Mr. John. Circuit Objectives and Requirements I recently came upon your website while researching circuits for a hobby project i’m working on. I certainly admire […]
Li-ion Emergency Light Circuit
The post presents a simple Li-ion emergency light circuit with over charge and low battery cut off features. The Circuit was requested by Mr. Saeed Abu and Y0f4N. Technical Requirement Bro thanks for ur reply. Actually im Pharmacist(M.Pharm) & Electronics is my hobby. So i go through ur mentioned link & i dont understand ur […]
LED Light Wave Effect Generator Circuit
In this post I have explained a simple LED light wave effect generator circuit which will sequentially create a difference in brightness over a chain of LEDs, creating a chasing light wave kind of visual effect.
Programmable Solar Porch Light Circuit
In this post I have explained a porch light circuit with programmable timer controller which enables the connected LEDs to light up or shut off after some delay, as preferred by the user, thus it’s not entirely dependent on the solar panel parameters. The idea was requested by “Unknown”. Technical Specifications It’d be neat if […]
