Making a 10/12 watt LED Lamp with 12 V Adapter
In this post I have explained the construction of a homemade 10 watt LED lamp using ready made 12 V SMPS adapter. The project was successfully built by Mr. Debabrata Mandal. In many of previous posts I have discussed the use of 1 watt white LEDs for making high efficiency LED lamps for implementing in […]
10 Watt Stereo Amplifier Circuit Diagram
With a simple design, this 10 watt stereo amplifier circuit offers good dynamics and excellent bass reproduction. Although its power output is modest, at 2 x 10W RMS, it allows for comfortable use in small-sized rooms, such as apartments. When paired with speakers with a minimum power rating of 20W, it will provide complete satisfaction. […]
