Simply flex your forearm muscle and hear the repulsor charge up, then relax your forearm to fire (lighting up the LEDs on your palm and playing explosion sound effects). As an added flair for realism, when you turn on the system, J.A.R.V.I.S.’s voice takes you through the boot up and calibration sequence.
Have you ever done something silly on a lark and then found it was a big hit? So it went with a “beta test” Halloween idea on the Adafruit Show & Tell last week of my electronic demon costume. This video is a summary of what was done there… and what I’m now scrambling to finish properly before the big day! Video on YouTube (please subscribe!) and Vimeo.
Some updates since this was shot: a Ustream chat participant during Show & Tell suggested using a paintball mask as a base. I’m currently working on the faux ribcage idea… there may be enough space to move most of the electronics there and have just batteries in the pack. We shall see!
HAPPY HALLOWEEN! Each day this month (Monday-Friday) we’re going to have a special “Electronic Halloween” post here on Adafruit. It will be a hack, mod, project or something we’ve found that combines all the best things about electronics and Halloween.
