To spice up the office around Halloween I decided to make a molded zombie arm that takes pictures of zombie lunch and posted them to the Twitter account @ZombieSelfie.
The build used a molded silicone arm (happens to be mine and my hair is still growing back), a custom steel mount to clip to an office partition, and a vibration sensor hooked up to an Arduino. Once the arm is slapped a photo will be taken using an IR Led and passed to the Eye-Fi card in the camera. The photo is then put into a Dropbox folder and If This Then That (IFTTT) posts the photo to Twitter.
Silicone Caulking: Find at Home Depot or a local store. Make sure it is type 1 clear silicone.
