Charged electrons flow from the power source along the negative trace (green) thru a resistor to the cathode. Like excited lemmings they jump the P-N junction emitting light. Finally, the spent electrons slide along the positive trace (red) to get charged up at the battery.         KEY battery is black negative trace is green resistor is blue […]

Find the inspiration. Overnight I saw @inventor_artist twittering about their laser cutting Hello Kitty! Valentine Day cards. In the blog post images I saw the solution to my circuit challenge. EUREKA! Design the circuit And gather the Supplies! SPOILER ALERT: 2013’s How To DIY eTextile Valentine’s Day Project is here.

Supplies: battery holder, 3V CR2032 battery, conductive thread, LED Test and Sew. Sew and Test. GLOW!

How to get an eTextile workshop of electronic novices off to a solid start? Be prepared. Very. Very. Prepared. Start with a basic LED circuit. Add some colour!!! Make enough LED circuit badges for everyone. First day of the workshop we will add 3V battery and an LED sewn in place with conductive thread. I can’t wait to see their […]
