Four amazing projects based on WS2801 led strip

Four amazing projects based on WS2801 led strip

WS2801 is a really cool led controller. In this post I’m going to show you some usage of this RGB led. An infinite Miror “Inside the mirror there is an RGB LedStrip with ws2801 driver – so it is obvious  to drive the mirror with the LedStripShow. Technically the move was easy, the connector to the […]

Enhanced NRF24L01 radio with a DIY Dipole Antenna modification

Enhanced NRF24L01 radio with a DIY Dipole Antenna modification

The situation was that I was only able to transmit and receive through 2 or 3 walls with a distance of about 50 feet, using standard nRF24L01+ modules. This was insufficient for my intended use. I had earlier tried adding recommended capacitors, but for me and my hardware got very little to no improvement. So, please ignore them in the photos.For my remote sensors I did not want the bulk of a unit like a nRF24L01+PA+LNA with a SMA Mount and exterior antenna. So I created this modified module.With this modified RF24 module I could go through four walls with a distance of about 100 feet.This module should also nearly double the distance over a standard nRF24 module when used with line of sight applications; like RF planes, quad-coppers, cars and boats (100s of meters).
