For this year's Rochester Maker Faire, I'm going to be showing off a couple things related to lighting up Lego stuff. This post is just meant to show where I am with the two things (for now) that I'll be showing off and what's left to do. This year, I will be showing off stuff in the "dark room". I've wanted to do something back there for a while, and without Interlock or RLUG exhibiting this year, and at Dan's suggestion, it seemed like a perfect time to do it!
Spaceship Earth lit with LEDs
This one is setting up an "SS Micro" Arduino (my favorite 'ardy form factor) to drive a handful of tiny neopixels to simulate the nighttime illumination of Spaceship Earth in EPCOT. This is based on @BenBuildsLego's EPCOT design. Buy his instructions, they're great!
Currently, I have everything as seen above. The model is essentially complete, and the arduino code is written with a LED strand "scene" concept. I've started to add a few transitions to go between scenes, randomize them, etc. Here's the current TODO list for it:
- Add illumination for Mickey
- Add illumination (and update the baseplates) for the fountain to be lit up
- More decoration around SSE
- Redo the wiring to be less conspicuous - replace the servo wiring with kynar/wire wrap wire
- New version of the light mounts?
Projection Mapping on the Mini Disney Castle
- The proportions differ a little from the real Cinderella castle slightly, and do not include the side walls.
- I need to buy a second MDC and use it for parts to adjust the model to fit the one in the video properly.
- Until they're back in stock, I can mock up the additions using Lego elements I already have.
- Video needs to be edited
- about 70% through, there's a slight jostling where everything shifts by a few pixels
- There is no fadeout at the end, so that needs to be done
- or remove the fadein from the beginning so it just runs forever.
- Playback device needs to be figured out.
- Perhaps a Pi connected directly to the DLP, that launches OMXPlayer or VLC on boot, with looping?
- Need to figure out a good tabletop + back screen system that's easily reproducable rather than the quick test seen in the photo above.
- I need to be able to just plop everything down at MakerFaire without needing to spend lots of time to tweak things endlessly.
- The geometries need to be 100% figured out and perfected before then.
- Try my other DLPs for best fit
- The above is with my Dell Short-Throw projector, which means it can be closer, and the background will be larger, which is really nice
- The BenQ projectors might have better results though and need to be tested.
- Perhaps figure out all of the geometries for both projectors and bring one as a backup, since they're all self-refurbed anyway. (leave the backup(s) in the car)
