Exactly, the dart has a spring within. It's sort of a reverse barrel design, the dart has a barrel with the propulsion spring inside and the "gun" has a stand which compresses the spring. The spring is compressed when you load the dart onto the turret and it clicks in,

Thanks, I'm glad you like it :)

Cool! I see you've really put some work into this. I also noticed that one of the LEDs lights up after a restart, guess it's getting some sort of signal from that pin because it's high on boot or something. I'll also have to change it. Keep up the cool work!

Sorry if I'm responding a bit late as I didn't see the previous comment. OTA uploads are a really cool idea, I did think about implementing that into the project but in the end I saw no use for it because I was happy with how the code worked and didn't see the need for anymore tinkering. As you are trying to improve upon the lighting effects I can see how it would be simpler and faster to use OTA. For changing the color you can just assign a different one to the pixel that you want and that should be it. Regarding the lag in the code, I did notice that sometimes the blinking of the built-in LED was irregular. I think that this has something to do with the way that the library for the webserver handles client (browser) requests but I'm really not sure. I am working part time on cleaning up…

I am working part time on cleaning up the code and also implementing some new features but the lag problem is still a bit of a mystery.

I'm super glad to hear you like the work! I'm sorry if the code is a bit messy, it was also my first time programming something like this "from scratch" so it's probably a bit hard to follow what's going on. Feel free to post any further questions you might have and maybe we can co-create a 2.0

Using the second hand to propel the walker would indeed be faster but my original idea was to make an "art" installation that would seemingly just sit there but eventually wonder of. Also, on my specific clock mechanism (and I'm guessing on most others) the second hand had almost no torque so it couldn't move the gears. I guess if it would be possible to make a completely friction-free mechanism it could move it but for this project there is no need for that.

I linked all of the parts needed as well as most of the tools I used. I also uploaded STL files for the parts, you’ll have to print those yourself :P
