LED Chakra is an ornamental lighting system which depicts or imitates a rotating wheel like appearance, by means of sequentially shifting Illuminated LED arrays. Indian subcontinent is a land of festivals and celebrations which mostly start from the month of August and continues until the New Year. All these festivals have one fundamental thing in […]

Underwater LED Boost Converter Circuit with Dimmer
In this post I have explained an LED controller circuit having a boost and dimming facility specifically designed for underwater shooting application. The idea was requested by Mr. Svein. The Circuit Request I came across your blog at https://www.homemade-circuits.com and thought I’d ask you a question regarding building or modifying a LED driver. I planning […]
Beacon Level Indicator Circuit for Combine Harvester Grain Tanks
In this post I have explained a beacon indicator circuit for combine harvester grain tanks. The idea was requested by Mr. John Bosch. Circuit Objectives and Requirements I would like to retrofit the rotating beacon grain tank level indicator system shown below, to my older combine harvester. The particular part of the system I want […]
Blinking 3 LEDs (R,G,B) Sequentially Using Arduino Circuit
In this post I have explained how to run or blink three LEDs in sequence using Arduino. The post was written and submitted by: Jack Franko PROGRAM/* make RGB LEDs to blink in series one by one at intervalof 1000MS */ int R = 12;int G = 11;int B = 10;void setup(){ pinMode(R,OUTPUT); pinMode(G,OUTPUT); pinMode(B,OUTPUT);}void […]
How to Build a Grow Light Circuit
In this post I have explained a typical grow light circuit application for plants in order to stimulate photosynthesis effect in an artificially lit environment using multicolored LEDs. The idea was suggested by Mr. Jack. The Circuit Objective I would like to donate to your site and pay you also for work you do on projects […]
Using Aluminum Strip Heatsink for Hi-watt LEDs instead of PCB
Whenever we come across using 1 watt LEDs or other higher watt LEDs, we are always advised to use high grade aluminum based heatsinks for safeguarding the LEDs from heat, and for acquiring optimal performance from them. Double Side PCB can be Costly However as we all know such PCBs are highly costly and could […]
