Rick & Morty Portal Gun

I had a week before going to Berlin for Halloween. I wanted to dress up as Rick (from the Rick and Morty show), and I absolutely wanted to make the portal gun!

I printed the 3D parts and made the electronics inside with what I had at home. At first I wanted to use a rechargeable battery, but I did not have enough time to order the components, so I made it with a switch and an alkaline battery. The potentiometer was supposed to change the “galaxy” value on the segment display, but the glue short-circuited it, so in the rush, the only solution was to increment the value automatically. The transparent plastic on top comes from a cream jar, the green foam from a sponge, and the black potentiometer knob (I lost the 3D printed one and couldn’t print another one) is a painted and glued bottle cap.
