This site is still under development and will likely continue to grow with new content and projects. I'm working on expanding its features and adding more interesting projects.

Latest Update

The latest project is the battery eliminator for the baofeng UV-5R which is working nicely.

Satellite Imagery Project

Overview

A project to receive and process satellite imagery from NOAA and METEOR satellites using a Raspberry Pi 5 and RTL-SDR v3 receiver.

Equipment Used

  • Raspberry Pi 5
  • RTL-SDR v3 Software Defined Radio
  • Antenna System
  • NOAA & METEOR Satellites

Important Announcement

The project has concluded succesfully and has shut down because NOAA satellite being retired and moving forward the images below won't be updated (with them being the latest taken from Crete,Greece)

Description

We use the Pi 5 as the controller for the RTL-SDR with the SatDump application so that the Pi knows which and when satellite passes above and what frequency to set the SDR so it receives the incoming signal. Then as part of the receiving system i've used a dipole for around 137MHz and with the help of the SDR we receive the signal and then the SatDump decodes it into images as seen below.

Baofeng UV-5R Battery Eliminator

Overview

A custom-built battery eliminator for the UV-5R radio, allowing them to be powered from external DC sources instead of the rechargable battery.

Features

  • DC power connector compatibility
  • Easy installation
  • No battery charge time

Status

Project is pretty simple and has finished successfully.

Description

The concept of the project is that if anyone uses the baofeng as a base station it could work anytime without interaptions from not having battery. So i used an external cheap power supply, a 3d printed case for the baofengs and a few cables and a DC adapter. To make this use the 3d printed case of a baofeng uv-5r and install the dc adapter in the back with cables going to the spot that the baofeng and the battery touch. Then simply connect the 3d printed case to the baofeng and then connect to that case the dc plug from the power supply at 7-8 volts. (Please check the voltage of the battery while on the baofeng by holding down the 0 button).
