It’s time to take a guided tour around the newest light show! In case you missed it, the newest show was released yesterday.
I kind of consider the new light show as the second generation of the first fountain show. However, there was so much more added that I couldn’t let it be an incremental update like version 5, 5.1 and 5.2. This was a great situation where I could sit back and watch the previous version and the current version back to back and see the improvements.
Something I wanted to focus on was to use the fountains better. With the backdrop and spotlights, it was a little easier, but looking back I found that there were too many dark moments in the first fountain show.
I tried to address the reliability issues from the previous version with a new nozzle design (even though it wasn’t perfect, at least I tried) and using wire to brace the nozzles to better hold its direction. It’s one challenge of the show that will continue until I come up with a better permanent solution.
The servo spotlights is something that I tried keeping a secret (I should stop doing that). I was a little too conservative with them, but the show still wouldn’t be the same without them. In the next show, I’d like to work on hiding the wiring and gearboxes of the servos.The backdrop performed well, though it still had the lighting issue I was afraid of. If there is more than one color on, the colors start washing out into white or an unwanted blended color. Still, some of the chasing effects look good.The light shows have never been overly complicated to wire since I used to give each LED its own pin on the Arduino Mega. In this version, I decided to use shift registers since I had made some shift register boards in my Eagle experiments and hadn’t used them yet. This actually made life easier because just a few wires have to run back to the microcontroller which is closer to the fountains. Without the shift registers, I’d be running a ton of wires back, and I barely had enough wire as it was. The only downside to shift registers is that programming takes a little more time to get right.
All in all, I’m happy with the results. I hope you enjoyed the show and I hope you’ll share it with others. Thanks for reading and happy holidays! Stay tuned for my last couple posts for the year!
