NEW GUIDE: John Park’s Secret Hollow Book Intrusion Detector @adafruit @johnedgarpark #adafruit
Build your own safe hidden in plain sight to store valuables — and rig an intrusion detector with Circuit Playground Express! This new guide will teach you how.
The guide will show you how to make your own hollowed out book, and then build a simple alarm with a Circuit Playground Express, or, even set up the Haven app on an old Android phone, just like Snowden would want you to!
Trigger warning: a book gets destroyed in this project.
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.
