I have just got the following email:
I am writing to let you know about our new Halloween Raspberry Pi 3 Giveaway!
We are looking for creative wearable tech Halloween costumes. Anyone can post pics/drawings of their creepy Halloween costume ideas featuring wearable tech here.
(entries by the 1st of November 2016). Example costumes: a vampire with red LED eyes or a wizard with a Raspberry Pi powered wand.
We will pick our 10 favourite ideas and announce winners on the 4th of November. Winners will receive a BOO! Pi Treat Bag containing the latest Raspberry Pi 3 Model B.
