I know you haven't posted in years, so asking may be futile, but I've always wondered: Why two motors as opposed to a single one with some sort of bearing/freely rotatable mount on the other end to avoid tangles? Expanding on that, are you actually using anything to avoid tangles, or is that the whole point of the two motors? Finally, are the motors independently controlled at all, or are they essentially in sync? If one were to order a unit, how hard and/or possible is it to replace the string with something else? Are there any specific limitations/requirements for the string? TIA! And I love ALL of your work!
Hi, I haven't posted in years mainly due to life :P. 2 kids, pandemic and supply chain disruptions, and massive inflation has put alot of my projects on huge constraints. I still sell them on my site and handmake everything but it takes me time to source all the materials and such. Regarding your questions: 1. Why 2 motors? First thing to note is that both motors have a mechanism in the hook which allows the string to rotate freely (the string is not "hooked" on the motor but uses knots threaded through a hole so that it can freely spin). This decouples the string from the motors so that the string can auto-correct itself if a tangle is incoming. Second is that 2 motors allows for redundancy, should 1 motor lose sync temporarily, the second one still functions as normally. If both motors lose sync (very rare), then out of luck. Also, these are DC motors so there is no feedback mechanism to "re-sync" them for cost reasons. 2. String replacement would be a bit difficult as it is custom cut, custom knotted (requires 4 knots) and is a very specific type of string (a wire knotted braiding nylon string). They are used mainly for bracelets. It also has be to very thin (in my case, 0.8 mm).
Hi! It uses a 12V power adapter with 2A current which means it is capped at 24W max power draw (it will never reach that though). In reality, it draws closer to 4W. Stephen

Also, the video above is very old, a recent video can be found here: ua-cam.com/video/qRbMLs3hjDI/v-deo.html
Hope I can buy this soon, when can we get this in stores?
Hi Stephen! Really awese job on the pisces lamp! I love it! Can I ask you how much power it uses? Kind regards

Hi! How loud is this lamp?
Measured to be ~15 dB (very quiet).
