PRETTY COOL!

How familiar are you with raspberry pi?

I know little but this looks interesting:

Editor’s note: The Raspberry Pi’s broadcast frequency can range between 1Mhz and 250Mhz, which may interfere with government bands. We advise that you limit your transmissions to the standard FM band of 87.5MHz–108.0MHz (see Step 5) and always choose a frequency that’s not already in use, to avoid interference with licensed broadcasters.

What better way to celebrate the launch of the tiny, $5 Raspberry Pi Zero than to build a project. The Raspberry Pi Pirate Radio is one of our favorite builds here at Make:, so it was an obvious pick to port to the new board. In case you missed our first crack at Pirate Radio, try it building it while you wait for your Pi Zero to arrive. PiFM was originally written by Oliver Mattos and Oskar Weigl, and revised by Ryan Grassel.

Pirate Radio is an extremely simple build: Cut and solder one wire to the Pi. The software installation and configuration doesn’t take too long either. Here is how we shrunk down the Pirate Radio into into a Pirate Radio throwie.

    I have a raspberry pi in my garage running a motion operated camera and a motion sensor for an outside light. They are excellent bits of kit and great for kids to learn programming. The new $5 one is a bit limited for me as it has no ethernet port, but its remarkable for $5

    The coolest raspberry pi build I have ever seen was a friend who wanted to go on an extended vacation, but leave his dogs at home. His son built a system that ended up rather complex. It had a wifi connection and a USB cam. He would email a specific command to an email address of choice. The device would receive the email, then it would SLOWLY release dog food, split into two separate bowls, one for each dog. It fed the two dogs over about five minutes so they wouldn’t eat too fast. During the feeding time, it would take a photo via the USB cam, then send an email back showing the status of the two dogs. They had a doggie door to go outside, along with a dog run that was totally enclosed. Every 3-4 days his son would stop by to verify all was well, but he had little intervention with the dogs. My friend was gone for SIX weeks and this system worked the entire time. He showed it to me one morning and it was awesome to see it work, all from one received email. He actually setup a scheduled email so he didn’t have to manually send it and each day he’d get a picture of his dogs eating their meal with no intervention on his part. Very cool. Me, I have never messed with a raspberry pi, but I’m sure I could find a ton of things one could do.

    I just dug up my Arduino Microcontrollers, sensors, two line LCD display, etc.
    It dawned on me that I left them to rot in a box since I had my heart troubles.
    One day soon I want to replicate a device we had at the paper mill. We had
    an optical device that measured distance to .003″ It would not only calculate
    the diameter of a roll, but based on the thickness of the paper (Punched in
    to a keyboard on the PLC) it could also measure lineal feet in a roll and even
    set proper web tension by measuring the “bounce” of paper entering the
    rewinder.

    The Arduino sensor I have is only good for .3″ but that might the basis of
    a distance measuring tool.

    PS I cruised through the sensors for Arduino and Raspberry Pi devices
    are staggering. They have have tiny solid state gyroscopes that could
    form the basis for building small guided missiles, can sense dozens of
    gases, sophisticated multi axis accelerators, vibration measuring
    devices and magnetometers, you name it.
