Serial LED Strip pt4

Testing Serial Strips

Progress continues on the Serial LED strips project. I’ve assembled a fair number of the prototype strips and have been experimenting with a few ideas. I’m really excited about this project… I keep thinking of new projects I can do with these little strips. However for now my focus is on testing the ones that I have in prep for a larger scale production run.

Also I got a lot of positive feedback from people at the Bay Area Maker Faire on the prototype strips I brought mounted on black acrylic (slapped together at the *very* last minute).

Today I set about testing the resistance on the power and ground rails. The resistance on these rails imposes a maximum length of serial strips that can be chained together before power needs to be re-tapped into the chain. Much to my pleasant surprise, the resistance that I measured closely matched my predictions. I had predicted a resistance of 5.70 mOhm on VCC and 6.48 mOhm on GND and I measured 5.79 mOhm on VCC and 6.42 mOhm on GND respectively. Not bad.

  1. mmmm… mandarin lime! Hansen’s Natural Soda is a “better-for-you”, great-tasting and affordable premium soda!
    Thank you for your assistance in marketing our delicious sodas to the geek contingent! Keep up the good work!

    I saw your stuff at the Bay area maker’s fair. WAY cooler then the bike displays.

    I know nothing about circuit design, but I have been looking for a LED setup that worked like this for years.

    So, are you planning on selling the complete boards? What kind of signal do you need to start a chain? Can you control the clock speed?

    Sorry, I am a little excited ^^;; anyway, you have a new follower.
