WISP – Re-programmable Microcontroller That Runs On Energy Harvested From Radio Waves

A new research initiative between the University of Washington’s Sensor Lab and the Technical University of Delft in the Netherlands has created a microprocessor that can power itself through stray radio waves and receive programmable updates in the same fashion. While the RISC-derived 16-bit microcontroller CPU is very weak compared to modern standards, it’s much more powerful […]

Send amp Receive Radio With A Single Chip

Send & Receive Radio With A Single Chip

Electronics News Updates / Ibrar Ayyub

Fitting transmit and receive capabilities of radio signals into one device may be impossible without using a significant filter, which is needed to isolate sent and received signals from each other. The major obstacle to achieve that is the weakness of the received signal compared with the much stronger transmitted signal. However, researchers from Cornell

Arduino and RF from kHz to 1 GHz

Arduino News / Ibrar Ayyub

We are very excited to announce the RFzero – a multipurpose Arduino RF and GPS controlled platform. The RFzero can generate frequencies from 2605 Hz and beyond 200 MHz. At the same time 28 I/O pins are available and eight of those are via an ULN2803A power driver. For more information please visit http://rfzero.net The typical use of

RFM69 output power

Electronics News Updates / Ibrar Ayyub

As I was mentioning in my 1000.1000 Hardware selection, I have opted for the cool RFM69HW radio module. Weirdly enough, in quite a few sources (big distributor and ebay) the higher power HW module is cheaper. So there is no reason not to get the higher power module, given quantity discounts. But I want it

ESP32 Internet Radio

Radio Projects / Ibrar Ayyub

The cheap MP3 VS1053 codec processor from aliexpress.com is told to be capable of decoding a variety of music formats, including Ogg Vorbis/MP3/AAC/WMA/MIDI audio. VS1053 is also capable of recording in Ogg Vobis file but all the guidance that is available on Internet are either for proprietary boards or for ESP32-IDF which not preferable to

Simple Arduino Radio with TEA5767

Electronics News Updates / Ibrar Ayyub

Ok, before to introduce this project, i want to apologize for my English, my native language is French… Secondly, this is my first Instructable, and it’s the first part of a biggest project (a MP3/SD card/USB/radio/bluetooth/clock/alarmclock/temperature/humidity on TFT touchscreen 3.5″) So, I was searching for a tutorial to create a simple Radio with Arduino… And

Arduino 433Mhz RF Wireless Data Transfer

Electronics News Updates / Ibrar Ayyub

The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is the 433Mhz ASK modules. They come in pairs, a receiver and a transmitter. They are ridiculously cheap, selling at $1 or less

Smart Phone Controlled FM Radio using Arduino and Processing

Wireless Projects / Ibrar Ayyub

In this project we will use an existing FM radio which went repair a long time ago, to convert it into a Smart Wireless FM Radio controlled using Phone, with the help of Arduino and Processing. We can convert any manually operated electronic device into a Smart Device using the same procedure. Every electronic device

Specan – A reboot of the W7ZOI/K7TAU spectrum analyzer

Electronics News Updates / Ibrar Ayyub

(A better, higher resolution diagram can be downloaded here: from my G Drive) If you don’t want to read this long long write-up, here is a summary: This spectrum analyzer costs less than $100 to make. It is just a superhet radio that has a log amp where the speaker should have been. You can
