I also followed the “LED sequins” tutorial to prep the SMT LED for sewing.
I’ve been working on this little project on and off for several weeks, and I’m so happy it’s finished! On the surface it’s just a TARDIS badge made of wool felt, like others I’ve made before. But underneath there are LEDs, a battery, and a conductive thread circuit. When the battery holder is snapped shut on the back of the pin, the pin lights up: the lantern on top, the “POLICE public call BOX” sign, and the windows. The windows are lit by an LED that changes color every few seconds (I like to imagine the time rotor is going crazy in there, even if one usually can’t see anything through the windows).
This project took a long time mostly because I had to gather a lot of new materials, including ink-jet printable plastic film, very thick felt (I cut up some coasters I found at Target!), and high-quality iron-on transfers- not to mention the LEDs, sewable battery holders, and conductive thread!
Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!
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.
