Every year, Vitamin T holds a #ATXPumpkinChallenge for creative agencies in and around Austin. Each team was given a fake pumpkin and the challenge of making a 15-60 second video. As the reigning champions from last year, [SiteGoals] had to up the ante. So they launched a pumpkin into space.
When first given the challenge, it only took the team 3 simple words to get started. Pumpkin. In. Space. What followed was a week-long frenzy of preparing the pumpkin for its maiden flight.
The pumpkin itself is pretty simple. A plastic jack-o-lantern painstakingly painted and detailed to look like the third Death Star. This is makes the title of the project a double-meaning: “Return of the Pumpkin”. They even included iconic spacecraft flying around the equator of the immensely powerful yet questionably vulnerable orb of destruction. Simply launching the pumpkin into space wasn’t enough. They built in a telemetry system and GoPro for recording the voyage. Stick around after the break to see the very entertaining making-of video, set the tune of the Cantina Band.

Building a Persistence of Vision globe is pretty awesome, but overlaying a Death Star pattern on the display takes it to the next level of geekery. Like us, [Jason] has wanted to build one of these for a long time. His success pushes us one step closer to taking the plunge and we hope it will inspire you to give it a shot too.
As he mentions in the beginning of his write up, the mechanical bits of these displays are really where the problems lie. Specifically, you need to find a way to transfer power to the spinning display. In this case use went with some DC motor brushes. These are replacement parts through which he drilled a hole to accept the metal axles on top and bottom. We hadn’t seen this technique before, but since motor brush replacements are easy to find and only cost a few bucks we’d say it’s a great idea.
The 24 blue LEDs that make up the display are all on one side of the PCB. They’re driven by an ATmega328 running the Arduino bootloader. [Jason] uses an FTDI adapter to program the chip. Don’t miss the video embedded after the break.
