WS4E – Ham Radio And Other Stuff

The Arduino Fox Hunt Transmitter will be documented in another post, in this post I want to document the Raspberry Pi SSTV Field Day Beacon. The one thing that I don't like about the Raspberry Pi is that it only has digital input/output logic lines.  It has no built in analog capabilities to read voltages, etc.. so you can't use it to easily interface with reading a potentiometer, a temperate probe, a light ...

Configuration Utilities for XBee Radios

Xbee Radios I purchased two XBee Series 1 Module (Freescale 802.15.4 firmware) from Adafruit.  These are manufactured by Digi and are low-power module with wire antenna  (XB24-AWI-001).  They have a 250 kbps RF data rates and operate at 2.4 GHz.  These radios use the IEEE 802.15.4 networking protocol and can perform point-to-multi-point or peer-to-peer networking , but as configured here, they do not mesh. ...

Raspberry Pi STL in a Box

I promised more details in the future about the Raspberry Pi STL build. Well, against all odds, I’m going to deliver! The project exists purely to solve a problem with getting audio between two sites for a hospital radio station. They currently use a costly dedicated line that’s purely analogue. Imagine the old fashioned exchange with patch cables everywhere and you’ve pretty much got the picture. Ok, I adm ...

Lunchbox Internet Radio Guide

What I've made is a radio with 6 buttons and a 20x4 LCD screen. There is an "ON" button, and "OFF", "BACK", "PLAY", "STOP" and "NEXT". It is connected to the internet via WiFi, and it powered by a USB hub connected through a Pi-Supply (http://www.pi-supply.com/product/pi-supply-raspberry-pi-power-switch/) so I get a proper shut down. And I use a USB sound card, as the quality of the on board is low at best. ...

TNC-X for Raspberry Pi (Packet radio) AX25

TNC-Pi is a special version of TNC-X designed to interface directly with the Raspberry Pi computer. It can connect to the Pi either via the Pi's serial port, or via the I2C protocol. In the latter case, a single Pi can support multiple TNC-Pi's at the same time, since each TNC-Pi can be given a unique I2C address. The firmware for TNC-Pi was based on the original TNC-X open source code by John Hansen, W2FS ...

Raspberry Pirate Radio

This simple hack turns your Raspberry Pi into a powerful FM transmitter! It has enough range to cover your home, DIY drive-in movie, a high school ball game, or even a bike parade (depending on the stragglers). PiFM software not only boldly enhances the capability of your Pi, but does so with nothing more than a single length of wire. This hack starts with the absolute minimum you need to run a Raspberry Pi ...

Raspberry Pi AirPlay Tube Radio

Vintage tube radios are nostalgic. The crackle of the game on the after dark high powered AM station from 500 miles away. The smell of the tubes and the warmth of the tones. They remind us of simpler times. Times when families sat together - not blankly staring unengaged at the TV, bur rather talking, reading, playing games and enjoying each other’s company. So often I see these beautiful old radios ripped ...

Internet Radio with Raspberry Pi

Since long past times, when Gugliemo Marconi has amazed the entire World broadcasting his radio signals from the Elettra ship, a subject held dear by electronic engineers has been radio transmission. After these years, the scenario has changed a lot, firstly with the appering of digital technologies (DAB, for instance) and, up to day, with the streaming of radio transmissions on internet network by the TCP/ ...

STLs and Raspberry Pis

It’s a weird one. When it first came out, people were struggling to figure out what to do with it. A surprising feature for something that sold out very quickly – the Raspberry Pi. Well, we’ve now come up with another use for them – it could replace your current STL codec. No, really. We’ve got a hospital radio station that’s looking to replace an old twisted pair line with an ADSL line for cost reasons. Ad ...

Raspberry pi gone vintage

The project is a vintage radio shell with a raspberry pi and external speakers inside of it. This project came from my need to have a tasteful raspberry pi enclosure without it looking like a raspberry pi case. I also had the need for some medium quality stereo speakers for my room so I incorporated both into this project. This project was completely made of reclaimed electronics. Step 1: The materials I us ...
