Raspberry PI: Connecting a Neo-6M GPS Module

I built a project using a Neo-6M GPS Module with the Raspberry PI. Now there are several USB solutions, and apps that work with them, but I wanted to show how to use a $20 GPS module with a a serial UART, and Python code to decode the NMEA strings. Then you can write your own GPS interface, or combine the data with Google Maps.
Hardware Setup:
The first step is to connect the GPS module to the Raspberry PI. There are only 4 wires involved, so it’s a simple connection.
Streaming Video with the Raspberry Pi Zero W & Pi Camera

I needed a really tiny yet cheap camera so I thought of the Raspberry Pi Camera module. The Version 2 Camera Module does 8MP with good quality, although a 5MP IR-Cut Camera better suited my needs.
About the IR-CUT Camera
The IR-CUT Camera works on Normal Mode by default. There are two ways to toggle between Normal Mode and Night-vision Mode.
1. By editing the config.txt
file:
1 |
sudo nano /boot/config.txt |
and append:
1 |
disable_camera_led=1 |
exit with save and restart your Pi then the camera will work on Night-vision Mode.
Raspberry Pi “Zero”: HDMI Monitors Has NO SIGNAL

When connecting a Raspberry Pi ‘Zero’ for the first time to a TV monitor with HDMI, and receive the message: “No Signal”. I tried it on several inputs and cables with no luck. Other devices work fine with the TV, and the cables so there can not be the problem. Then I tried a computer monitor with HDMI, also with no luck. What is happening?
I’ve investigated the problem for a couple of hours, before finding the solution.
The Raspberry Pi ‘Zero’ outputs a relatively weak HDMI Signal. Some devices may not immediately notice the Raspberry Pi ‘Zero’s HDMI Signal, or may not go through the negotiation process.
