For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless […]
This is simple radio receiver project which is capable to receive aviation radio voice signals which are transmit between 118MHz to 138MHz in AM (A3E). We got initial idea of this project by reading Sverre Holm’s (LA3ZA) article about “cheap VHF receiver project For more detail: VHF AIRCRAFT RADIO COMMUNICATIONS RECEIVER

Solar charging, via the panel on the back. * 12 position switch to select channel number * Seek up / seek down controls and ‘store’ button * RDS display of call sign * Frequency display * Battery voltage display * Solar charging current display The software still needs a bit of attention. Its fine if

I’ve settled on the lighting industry standard of DMX as my overall control protocol as I explore the world of blinky lights. This universal control method is electrically robust, radio transmissible, and flexible enough for my needs (not to mention the needs of major concert, theatrical, and entertainment venues.) There are a variety of DMX

I was looking for a way to handle wireless communications between two Arduino boards. Other options like Xbee or Bluetooth were going to cost $50 to over $100. Then I found a cheap RF transmitter and receiver at Sparkfun. The total cost is only $9! Here are a few limitations to RF solution: Communications is

This project used the Si470x FM radio receiver and an ardurino to make an over the counter kitchen radio. These parts had been purchased for a different build that unfortunately met a premature end. The concept for this project is simple. Play my favorite news and music radio stations while having a form factor that

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

I’ve been visiting local convenience store (Dollarama, here in Montreal, Canada) and notice nice looking FM Radio, just for only $3. Why not to try to interface it to my lovely Arduino? Idea looks quite challenging, the same time what is the point in interfacing a DSP radio shield to arduino? I don’t need a

I have two good AM transmitters – one I’d built using a single 6888 Tube plus an old KnightKit Broadcaster that I’d refurbished, as well as a high-quality solid state transmitter from SSTRAN that I use to play music over the several antique AM radios I’ve repaired or refurbished. I wanted a high-quality FM Stereo transmitter to

The blimp is controlled by a transmitter on the ground, operated by a human. There are three control levers– one for each motor, and one for the servo that rotates the axis they’re attached to. You push / pull to make the motors speed up or slow down; they’re controlled individually, it’s like driving a
