I have seen lots of great Halloween Prop builds but this Halloween Electric Chair that Robo and his son made for a school haunted house takes the cake. I love the mix of pneumatics and electrical. The sensor is IR which I obviously love since that is exactly how my Stair Lighting System is activated except by a leg not an electrocuted head! The sander under the seat is sure to give the unexpected guest the shock of their life, and if that isn’t enough the burst of air from above will seal the deal. The lighting from above and below the chair is a great effect and dimming of the room lights really enhances the look of the chair in action. Hopefully Robo uploads some build pictures, schematics and code for this cool project so that others can enjoy the idea.
