This is the test LED board we plugged in to make sure everything was OK before mounting the real LED assembly.

This is the artwork called the "Weather girl" you can see the light in the middle, unfortunately not very bright in the day. (the guy on the ladder is the metal basher that built the work, just fixing up the brakes)

 

 

The work is located on the terrace/cafe of the Museum of Contemporary Arts (MCA) at circular quay.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...
  5. When your question is resolved, mark the solution: https://www.avrfreaks.net/comment...

I remember the "potting compound" thread for the coils. It's nice to see the completed project.

 

BTW: Weren't you ever tempted to simply bung in a battery and an off-the-shelf charging converter ?

It looks like the teletubbies windmill with a flattened teletubby!

...but then you need a micro to check the speed of the turbine to see if the wind is blowing otherwise people would know you're cheating if the light would always be on. wink

All the power it generates gets fed to 25 Blue LEDs

Instead of driving leds, use this power to drive a fan, which will keep the turbine spinning.  It can be finicky to get it to work; don't give up, keep trying. 

When in the dark remember-the future looks brighter than ever.

Wile Coyote tried something similar!

I've told you before about the member of the Swedish Parliament, Committee for Energy, who was in a hearing visited by members of the The Royal Swedish Academy of Engineering Sciences. He seriously asked if electric cars could not have their batteries charged while driving using a turbine on the roof (he used the term "propeller", which I believe is not the correct term here).

 

There is a YouTube video of the "event", for speakers of the Swedish language to be amused/flabbergasted by: https://www.youtube.com/watch?v=... .

 

He sort of sneaks up on what he's after, and while this slow sneaking is going on you can see the members of the IVA starting to cork-screw in their chairs. Hilarious, if it wasn't for the sadness of it. Sort of watching Fawlty Towers (I have to go out in the kitchen for some too embarrassing passages) but it's "real life" and the man is preparing stuff for the Swedish Parliament to decide upon. Doh!/Facepalm!

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

We have a similar problem... too many lawyers in positions of influence and power and not enough real thinkers. Come the Revolution!
