Breadboarding done. Interior Shell Structure Start.

I am now putting her all together, slowly. There is still some light architecting and constructing to do as I am figuring out the interior design as I go. I cut the power jack off my RBBB board as planned and it fits nicely although the double pointed pentagon structure I built (connected at the points [ like this: >< ], with a toothpick through the middle of the two) to hold up the board is a little higher than I wanted because I didn't take into account the soldering sticking out of the bottom of the board. I've also started building the mount for the 7-segment display which, I’m sure, will present it’s own challenges. But the code is pretty much there! I ripped a bunch off from Ahmad’s ThermoLamp code which saved loads of time. I added a dimmer mode (which I probably should have used while photographing the breadboard) and I probably still have to clean up the code a bit but for now I’ll be concentrating on building the interior, the shade covering, and the power circuit (I have to build my own holders for 2x3v disc batteries – and it would be cool to do some transistor / photocell kind of thing but I’ll probably just have a switch).

Geodesic Shell

This is still in the works. It’s an idea for a night light with a thermistor that changes a tri-color LED based on the temperature ( inspired by baby sleeping temp recommendations ). Funnily enough, my friend Ahmad (see his new blog) had the same idea way before I did. He gave me his code and convinced me to add a 7-segment display which I am working on now. But here’s the geodesic shell that I made from toothpicks and glue. I’ll keep updating as I go.

I got my Math for geodesic domes from, once again, hilaroad and also JMEMantzel. I recently bought Geodesic Math and How to Use It by Hugh Kenner but my dome was already in the works by the time I received it in the mail so I’ll have to use it for future projects.
