This great Ratsberry Pi was posted up too late last year for you to build your own– now’s your chance! Control a bunch of servos with a Pi — check out our tutorial as well! From HariEdo:
I found some squeaky rubber rats at the local dollar store last year. Of course I had to buy ten of them, and then work on some sort of project later. Once I got my Raspberry Pi, I knew I had to combine these into a Hallowe’en decoration project.

HAPPY HALLOWEEN! Each weekday this month we’ll be bringing you ideas and projects for an Electronic Halloween! Expect wearables, hacks & mods, costumes and more here on the Adafruit blog! Working on a project for Halloween this year? Share it with us on Google+, in the comments below, the Adafruit forums, Facebook, or Twitter— we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). Tune in to our live shows, Wearable Electronics with Becky Stern and Ask an Engineer, where Adafruit store discount codes are announced– get the most bang for your Halloween buck!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
