Nyan Cat hat will be the hit of the party…. for about one minute

Seriously, this Nyan Cat hat is the only part needed for a fantastic Halloween costume. It looks pretty good in this still image, but we dare you to watch the clip of it in action (embedded after the break) without letting a beaming grin creep onto your face. Everyone’s going to just love this… until it starts to get really … Read the rest

Halloween Props: Monster in a box

This furry Halloween decoration proves to be a simple build, but it’s still quite popular with the little ones. [Chris] had a Halloween party for a group of 2-5 year olds and this monster that peeks out of a box was a huge hit. The trick really isn’t in the complexity of the build, but in the interactivity.

[Phil] over at Adafruit crashed last Sunday’s Show and Tell with an amazing demon costume that includes a voice changer and animated LED matrices for The Eyes and mouth. He just posted how he built this costume, but you’ve really got to Watch the video to see how awesome this build is.

Every demon needs a scary voice, so … Read the rest
