Note: Please note that NOOBS is no longer supported or recommended. Please switch to Raspberry Pi Imager. If you still require multi-boot functionality, consider switching to PINN, which is an unofficial fork with additional features. Install NOBS for Raspberry Pi To…
Raspberry Pi 2 Model B delivers 6 times the processing capacity of previous models. This second generation Raspberry Pi has an upgraded Broadcom BCM2836 processor, which is a powerful ARM Cortex-A7 based quad-core processor that runs at 900MHz. The board…
This solar power supply circuit project uses the 1.2v rechargeable battery and solar panel. The solar panel charges the battery when sunlight is bright enough to produce a voltage above 1.9v. The regulator transistor is designed to limit the output voltage…
Calculating watts Power[watt]=Voltage[volt] * Current[Ampere] if the panel is rated as 5v 200 mA then Power=1 watt Wiring multiple solar panels Parallel wiring This is required if your application need more power than rated. By connecting the positive terminal of…
How does radio works? Audio signals are transmitted by imposing lower audio frequencies on the high frequency carrier wave. In other words the audio signals are added to the carrier frequency. Its amplitude is modulated. At the receiving end, a…
The Raspberry Pi Model B+ is a credit-card sized computer board that’s up and running when a keyboard, mouse, display, PSU and SD card with installed OS are added. It’s a miniature ARM-based PC which can run many of the…
