I just ran the code and I get nothing out of the non digital outputs.

Comments deleted.

I'm thinking of making one of these. I looked to see how much the parts would cost to be printed here, and when I go to the screen to do so, it lists all 3 items as $0.00. It then also says the firefly may be too small to print. I also checked with shapeways and they are saying that the walls of the firefly are too thin. I'm not quite sure what to do, I've never gotten anything 3d printed before.

I scaled mine 2540% in Slic3r to obtain the 0.92in (23.36mm) x 0.775in (19.68mm) x 0.304in (7.71mm) dimensions.

someone has the code for arduino?

Can anyone please fix the scaling on these files and repost new files. Thanks In Advance.

I accomplished this using a PIC12F683 (about a buck each), 8 yellow or green SMD LEDS, 4 resistors, one .1uf cap, a switch (or jumper), and a printed 2x2032 lithium battery holder. The 8 leds run in 4 groups of 2 and a small PCB I home etched. Code was done in GCGB (compiled basic).

Here is a short video of it running (the lights are on a centerpiece with moss and flowers around them. They do not appear quite a bright in real life and are more "firefly-like" in person.


what size do you scale them to I open the fireflys up and there microscopic

It should scale if you import it in inches. If that doesn't work, scale it so dimensions are 0.92in (23.36mm) x 0.775in (19.68mm) x 0.304in (7.71mm).

I'm planning to use your arduino code for an led sign. I'll play with the int delaymin=10; int delaymax=1500; numbers to get a slightly faster led frequency for the effect I want. Also planning to use leds in series pairs to eliminate the 220ohm resistor.

I am glad to see someone did this. :)
