AVR HV Rescue Shield Code Update 1.2

Version 1.2 of the Arduino sketch that powers the AVR HV Rescue Shield is now available for download.

The revised sketch now displays the target AVR’s existing fuse settings before asking you for new ones.

I also cleaned up and reworked the code in a couple places, but these changes shouldn’t affect the existing functionality.

If you have any issues or questions about the new code, post them in the support forum or contact me directly.

Bluetooth Headset inside a [toy] Handgun

MayorMike, inspired by the article I wrote for Make vol. 20 (Retro Wireless Handset), stuck a bluetooth headset in a plastic toy gun to create his Handgun Bluetooth Earpiece Project.  The best part – the earphone is located at the end of the barrel, so to answer a call, you stick it up to your ear.  Genius.

The innards are shown below.

Nice work, MayorMike!  May I suggest that you pair this with a Hand Grenade MP3 Player?
