One of our most electronically ambitious projects, the Transistor was created for Supergiant Games as a photobooth accessory similar to the Cael Hammer project from Bastion. Attendees at PAX could pose with the blade and get photos emailed from the event, which was a huge opportunity for various cosplayers to act out all sorts of shenanigans.
Vacuum formed parts created a hollow translucent shell around over 150 RGB LEDs. The Transistor has several electronic “modes” – it can pulse slowly in green or red as shown in the game, and it can also play voice lines spoken by the sword via a remote control while LEDs pulse to audio levels. Two internal speakers allow audio files to play directly from the sword, and an external audio jack placed at the base of the blade lets the sword act as an audio source to an external receiver. This was useful in setting up audio at the Supergiant Games booth to be heard over the rest of the convention. A second audio jack allows custom audio input, allowing people to talk “through” the blade. Lastly, the sword can operate either on an internal LiPo battery pack or be plugged into 120VAC power for continuous operation.

As I’m a huge transistor fan myself, two replicas were created. The Supergiant Games replica debuted at PAX Prime 2015, while my personal copy was used alongside a Red cosplay at DragonCon a couple weeks later.
