Evil Mad Scientist has released the designs of their Resistor Wallet, the protective and easy-to-read packaging used in their Three Fives kit:
Many of our soldering kits have multiple resistor values, but the Three Fives kit is unusual among our projects in having nine individual resistors of different values. This presented an interesting problem: how to make user friendly packaging to make it easy to find the right resistor. Sure, you can read the color code stripes, but that can be a pain for folks with color blindness or just plain old poor vision.
Our solution was to design a custom wallet, modeled after needle packets, to hold and label the resistors with their locations & values. The resistors are dropped into slots, secured with a label, the cover flap is closed over them and then tucked under a tab. During use, each resistor is simply pulled out from under the adhesive label.
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
