This is part of an on-going series of posts about littleBits projects. littleBits is available in the Adafruit store – Starter Kit, Extended Kit and Teaser kit.
As the spookiest day of the year approaches, we here at littleBits have been cooking up some supernatural projects to trick out your Halloween. The interactions in both of the following projects are surprisingly haunting and would be a great addition to any haunted house or, if you are the Adam’s Family, a permanent wall fixture.
Great Uncle Edward
This portrait may just look like a normal photograph, but take a step closer and you will notice something very strange. The eyes in this portrait physically move, and not only that, they follow you wherever you go! We used an old frame, a photograph, motion triggers, a servo, and a series of logic Bits to achieve this unnerving interaction. This is one of our most complex circuits yet! Learn more here
‘Come with us’, two small ghostly figures beckon. As you draw closer you hear a rattling sound. The figures suddenly quadruple in size and appear very close to you. Run away!!! The Ghost Projector uses a motion trigger and an inverter to switch between two ghostly images printed out on transparency paper and projected on the wall with bright leds. The images are angled in such a way that they appear in the same frame and alternate depending on whether or not you are detected by the motion trigger. More information about this spooky light trick here.
Stay tuned for more Halloween project ideas next week!
