Raspberry Pi Goblin Detector #piday #raspberrypi @Raspberry_Pi
This is a cute Halloween project for kids made using a Raspberry Pi. Via Raspberry Pi Pod. Read the full tutorial here.
A Python programming project for the Raspberry Pi together with the Pibrella add-on, plus a standard passive infra-red (PIR) movement sensor, for the Raspberry Jam at PyCon UK 2014. Also suitable for other 3-wire sensors.
My eight-year-old daughter Annabel’s bedroom is plagued by goblins (her five-year-old sibling twins). Annabel and I created a Goblin Detector, which guards her bedroom while she’s out, like a burglar alarm. If it detects movement, it sounds a buzzer. We used the Pibrella add-on to make the wiring easier, to give us some lights, a button and a buzzer ready-to-go.
1x Raspberry Pi – any model A, B v1, B v2, B+ – around £25.
1x Pibrella – £10
1x HC-SR501 PIR Motion Sensor Module – should be around £3-£5 from eBay. Teachers – look out for listings with bulk discounts for 3, 5, 10 sensors; I’ve seen ten for under £10 if you’re prepared to wait for delivery from China.
3x Male to Female Jumper Wires – usually supplied as a coloured strip of 40 or so for about £2-£4
1x small empty clean margarine tub – optional, to house the sensor.
A case, optional. I used the Pibow Coupé (£8.50) which gives easy access to the GPIO pins but there are many cheaper alternatives or even a paper/card case for the model B and for the B+ that you can print out for free (remember to select the “actual size” option when you print).

Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
