A cryptex is a renaissance era puzzle or safe that was originally designed by Leonardo Da Vinci. It is now more widely known from the book, “The Da Vinci Code”, written by Dan Brown that has also been made into a movie. Da Vinci’s original concept included a fail-safe inside the cryptex that destroyed the contents if someone tried to force it open. This was achieved by a small vial of vinegar breaking open and dissolving the papyrus that was inside. The version that I designed does not include this, however it can hold much more than paper. I designed it to be a good size for most small items such as a flash drive (probably more than one), or jewelry. It can also be used as a unique gift for someone that is also given a riddle or clue and needs to solve it to get to whatever is inside. This instructable is fairly short, however it may be a bit confusing as to how to put it together and it took me a while to make a working model so I want to make sure others can make it as well.
As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email email@example.com to let us know about your post so we can blog it up here.
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.
