  • Hello, may you help me build one like this? send me the instructions? djrolf@bol.com.br thanks

  • I need one of these. Just to shock my friends. mwaha ha ha ha

  • bet thats fun to tie

  • I'm thinking about putting together one of these. Looks great. How much battery life do you get out of the AAAs?

  • @PoprocksAndCoke I really want to make this one, so I've made some calculations and ordered the parts.

    At any given moment, just one LED is on. So 20mA are used.

    On a CR2032 coin cell battery (225mAh), this should lead to about 10-11h of battery life.

    I'm going to be using a MSP430 uC (low power stuff!), so I think that the micro controller power consumption should be negligible, compared to the LEDs.

    When everything arrives, I will keep you updated :)

  • If its not too much trouble, would you mind sending me the schematics?

  • your tie is amazing :D

    I made one myself the other day but I had to customice a pre-assembled LED-module...

    thumbs up for your talent, mate ^^

    greetings from Germany ;D

  • cool tie :D
