Here’s another of the great #electronichalloween projects shared back with us from the Halloween season from our community. Paul shared: “Built a “fortune-telling” Seance Table for Halloween using Adafruit NeoPixels controlled by a Trinket. Turned out really awesome!” Check out further details on the project page. Seance Table:

We came across this Seance Table at the How to Haunt Your House website and we decided we had to build our very own Seance Table for Halloween….

We wanted to take the table design one step further and make it interactive for our guests. The idea was to have a crystal ball in the middle and have people ask questions and have the “spirits” answer them. To make this happen, multi-color LED lights were placed within a ceiling light fixture and controlled with hidden buttons under the table. The light fixture was painted and jeweled and Adafruit NeoPixels were used for the LEDs. A Trinket microcontroller controlled the light colors and patterns from button inputs. The whole thing was easily wired up on a breadboard and powered with a Lithium Polymer battery. One button puts the crystal ball into “standby” – pulsing white, another sets the “calculating” state – rapid rainbow colors, and the other two control “yes” – green and “no” – red.

What really made this build special for us is that we all collaborated on it – from the pattern transfer to the inking to the finishing and fabric work and to the concept and execution of the “crystal ball.” We think it turned out great and wanted to thank How to Haunt Your House for the plans and designs….

Adafruit Trinket – Mini Microcontroller – 5V Logic: Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board!
