My light–up TARDIS pin uses a color-changing LED, an SMT LED (behind the POLICE BOX sign), conductive thread, and a sewable battery holder– all from Adafruit Industries.

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!
