Awesome idea and build from instructables user ossum.
I like to think that Back to The Future’s Doc Brown would have a security briefcase of his own design, instead of a combination lock, it would only open at 88MPH
I used the Mediatek Linkit One board and an old briefcase to make my own version.
This project is undoubtedly silly, but through it I will describe how to use the Linkit One’s GPS to determine speed as well as how to display it on a seven segment display.
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.
