Step 3: The Electronic

  1. I used double sided tape to fix the battery in the case (Pic #1)
  2. the mini breadboard has a self adhesive backing to fix it (Pic #2)
  3. breadboard the default circuit (Pic #3) by following the step-by-step instruction sheet (Pic #4). Click here to get a bigger version. Cut the leads of the LED, resistors, capacitor and transistor to fit in the tin.
  4. Close the tin.

Cool! I might try this (with an ATtiny85).
Its a great idea to use a µC for that. I am very curious about your circuit!
Here is mine. It's kinda lame. I didn't have any orange or yellow LEDs so I made a tree.<br> <br> <div class="media_embed"> <object style="height: 390.0px;width: 640.0px;"><param name="movie" value="http://www.youtube.com/v/pQHQpeSy3Yg?version=3&amp;feature=player_detailpage"><param name="allowFullScreen" value="true"><param name="allowScriptAccess" value="always"><embed allowfullscreen="true" allowscriptaccess="always" height="360" src="http://www.youtube.com/v/pQHQpeSy3Yg?version=3&feature=player_detailpage" type="application/x-shockwave-flash" width="640"></embed></object></div>
Thanks for sharing. Would you also post the circuit and the code for the &micro;C?
I will post a few pictures of it in an hour or two.
Very cool entry to the Advent Calendar. <br>A contest within a contest is an original idea too :)
Thank you!
