Issue 16 — HackSpace magazine – Can I hack it? A smart pixel purse

This Project Mc2 Smart Pixel Purse, looks like a handbag (known as a purse in American parlance) but, in reality, it houses lots of very hackable electronics. The purse was made as part of the Project Mc2 Netflix series, which involves a team of girls working for government organisation NOV8 as spies, using their STEM skills to protect the world.

The smart pixel purse is a vital piece of equipment, but can we hack it? Let’s find out! The purse is held together with a mixture of friction-fit plastic and six cross-head screws, and so taking the purse apart is relatively simple. The LED matrix screen has a clear plastic screen to protect it, and to separate the pixels, so that our image/text is clear.

If you ish to use the matrix with a Pi, then purchase an Adafruit RGB Matrix Bonnet for Raspberry Pi, or the Adafruit RGB Matrix HAT – these both come with on-board level shifters and an IDC cable, so no messy jumper wires! We tested our board using another Adafruit product, an RGB Matrix Shield for Arduino. Coming as a kit, we soldered everything up and installed the libraries necessary. Then a quick demo script was tested, and everything worked.

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 circuitpython2022@adafruit.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.
