Surprising enough with the help of Raspberry Pi it should hardly take less than half an hour to set up your own FM broadcasting station and get on air within a local area. This program generates an FM modulation, with RDS (Radio Data System) data generated in real time. It is based on the FM transmitter created by Oliver Mattos and Oskar Weigl, and later adapted to using DMA by Richard Hirst. Released under the GNU GPL v3. Learn more. ANTISPAM: What does the 'D' in SDR stand for? 1 star 2 stars 3 stars 4 stars 5 stars. De Raspberry Pi is een minicomputer in creditcard formaat. By default there will be an audio file downloaded along with the program called star_wars.wav. When you enter the desktop of PI, search for network option and connect your Pi to your router. a Sangean PR-D1 portable receiver from 1998, and an ATS-305 from 1999. a Samsung Galaxy S2 mobile phone from 2011. a “PCear Fm Radio”, a Chinese clone of the above, again using RDS Surveyor. The idea is to use a Raspberry Pi and the Pi-FM-RDS software to transmit a simulated numbers station. The modulated signal will be given out through the GPIO pin 4 of the Raspberry Pi. For this run Pi-FM-RDS with the -ctl argument. This allows you to pipe the output of a program into Pi-FM-RDS. However, recently Simon Roses wrote in and wanted to share his project where he created his own numbers station at home. ​How to Build a Raspberry Pi FM Transmitter, https://github.com/markondej/fm_transmitter, IoT Based Contactless Body Temperature Monitoring using Raspberry Pi with Camera and Email Alert, DIY Raspberry Pi LoRa HAT - LoRa Communication between Raspberry Pi and Arduino, Social Distancing Detector Using OpenCV and Raspberry Pi, Block all your Ads with PI-hole on Raspberry Pi, Driver Drowsiness Detector System using Raspberry Pi and OpenCV, Turn Your Raspberry PI Zero into A VPN Server with OpenVPN, Raspberry Pi Based Industrial PC with 15” Touch Panel Display and Advanced HMI Support, Interfacing GSM Module with AVR Microcontroller: Send and Receive Messages, SRP0310 / SRP0315/SRP0410 / SRP0510 / SRP0610 Series Shielded Power Inductors, TBU-RS Dual Channel TBU® High-Speed Protector Series, AEC-Q200 Compliant Thick Film Chip Resistors - Model CRxxxxA Series, Model SF-0603HIA-M/SF-1206HIA-M Series SMD Fuse Families, Chip LAN Transformer Module - Model SM41126EL Series, RTG4 Field Programmable Gate Array (FPGA) in a Ceramic Quad Flat Pack (CQFP) for Simplified System Designs in Satellite and Space Probes Applications, Automotive Microcontrollers from STMicroelectronics to Maximize Safety and Security in Next-Generation Domain/Zone Architectures, Open Source FT2232H-based, Multi-protocol, Multi-voltage Tool For Hardware Hacking and Reverse Engineering, Health Sensor Platform 3.0, Reference Design from Maxim Integrated to Reduce Development Time of Healthcare Wearables, AEC-Q101 Qualified 700 and 1200V Silicon Carbide (SiC) Schottky Barrier Diodes for High System Efficiency and Reliability in Electric Vehicles.
