1. Video demo of creating and deploying a simple .NET Gadgeteer project using Visual Studio 2012 Express for Windows Desktop.

    Important Links:
    Setup your development environment for working with GHI's Gadgeteer boards (other vendors should have similar instructions on their sites):

    Firmware updating for the FEZ Cerberus family of boards (includes FEZ Cerbuino Bee) - Follow the instructions at https://www.ghielectronics.com/docs/46/fez-cerb-family-developers-guide#3253 to update the loader to the correct version matching the desired firmware version, and then follow https://www.ghielectronics.com/docs/127/firmware-update to update the firmware. Note that before you update the firmware, you will have to install the GHI SDK, as listed in the first link above.

  2. Teaching my kids about electromagnetism, with this very easy and cool project. One AA battery, three rare earth magnets, and a length of copper wire = FUN

    If you want to try this one yourself, just be aware that the battery and wires (depending on the wire gauge you use) can get quite hot. Be sure to give the battery a break every so often, and probably not a bad idea to wear safety glasses just in case.

    Simple steps. Get a AA battery (other sizes will work, too, but you'll need to shape your wire appropriately), one or more round neodymium magnets with a conductive coating, and a length of bare copper wire.

    Shape the copper wire so that it has a point, centered towards the top, that can balance on the top of the battery, and bring the two ends down so that they form semicircular loops at the bottom, just below the level of the bottom of the battery.

    Attach the magnet(s) (I used three, so I'd have plenty of area for the wires to touch), and align the wire loop so that one side of the loop is on one side of the magnets, and the other on the other side. The wires should be able to touch the sides of the magnets, but should not touch each other.

    If the wire loop doesn't start spinning on its own, you may need to give it a push. You can tweak the shape of the wire to get better balance or better contact with the magnet(s).

  3. Modified version of the default game for the Outrageous Circuits RETRO game console. Added score tracking, and increasing difficulty (speed) as score goes up.

  4. A quick video of some of the Gadgeteer and MIDI projects on display from myself (Devhammer) and Pete Brown at this year's Mid-Atlantic Developer Expo conference, which ran from June 27th-29th, 2012.

    Among the projects shown are Devhammer's RGB LED tower demo, made possible by code written by Dave Durant, A Gadgeteer Arcade Enclosure running a Gadgeteer version of Pac Man, written by TinyCLR.com community member taylorza, my Gadgeteer Helicopter controller, and on Pete's table, his Gadgeteer project board, which was sending control info to his Sammich SID MIDI synthesizer. Also shown were a couple of Pete's microcontroller prototyping boards.

  5. Short demo of the LPD8806 digitally addressable RGB LED strip being controlled by the GHI FEZ Cerbuino Bee .NET Gadgeteer mainboard via SPI.

    LPD8806 driver code supplied by Dave Durant, and available here:

    http://www.tinyclr.com/codeshare/entry/414/

    The code was written for .NET Micro Framework v4.1, so I had to tweak the driver just a bit to work with NETMF v4.2 which does SPI a little differently. Dave also has a full tutorial up at:

    More info on the LPD8806 is available at:

    Finally, a big thanks to Eric Hall (aka @ransomhall at http://www.tinyclr.com/forum/) for arranging a group order for these awesome LED strips. Fun with blinkies, FTW!
