Hello fellow light and lighting tinkerers,
though I have been absent for a while due to private reasons, some of you may remember me and my saltstone lights (@KandelaLabs). I am building up a small lighting business with many opportunities waiting, but sadly I lack in the technical skills to build a fitting WLED controller for myself. So I recently focused on prototyping the frames around a commercial lighting system instead of tinkering around with WLED – Until now
Nevertheless the frames are more or less light source independent, so I still could (and plan to!) use my “matrix controller” into them. My goal here is to be able to order them in smaller (and soon maybe bigger) badges pre-assembled, so I can just put them into the frames/lamps in conjunction with a ws2812b matrix and a fitting power supply.
Yes, there are already some commercial available ones (hello Quindor and some other designs made by you guys (hello srg74 ;). But as the controller must fit specific requirements, it has to be a dedicated design (or at least some variant of the existing ones). Without going into details at this point, some crucial requirements are
The controller has to be as flat as possible while exploiting the larger amount of the base area (aprox. 10 cm x 4 cm). The current ones are too “clumsy”.
As a (Natural) User Interface, Id like to implement a rotary pushbutton wheel for a comprehensive, intuitive and haptic control (I already put a lot of thought into a menu logic for this, but I see it as a bit of a dedicated sub-project and will probably discuss this in a dedicated thread)
All the I/Os must be next to each other at one side (DC, power switch, pushbutton wheel, mic/line-in (optional), status LED (optional))
My primary model is designed as a “mobile” light, so it also has to be powered by an internal power supply (powerbank via USB, LiPo plus MCU or a 18650 based solution)
The controller is focused on three sizes (8x8, 8x16, 16x16) of ws2812b matrices, so it (and the PSU) has to be less universal
Though there are still open questions, the core requirements should hold up further design iterations. But alone I cant get closer to something more MVP and less frickelfrackel (One of my older but still very impressing prototypes below).
Soooo, here I am looking for some (at least semi-professional) help that can go into different directions:
We can handle this as an open design project. If I get this done with your help in this way, I am willingly to share my designs and construction plans with the community. So everyone can build a Lumen light for herhimself (or variants of it, there are already more awesome use cases and designs for such a controller
I am pushing this project as hard as I can to be a (small) ambient lighting startup that does not only produce awesome lights but also is present at festivals, open airs etc. I am open for some joint ventures and would be happy to have a technical developer for these activities one day; the controller is the entry to this world, so possibilities are waiting and I am looking forward to 2022 when culture will rise again
I even could imagine just buying the controller from an external source
Or of course it can be a mix of all this.
Bottom line: Alone I am stuck at this point and would be really happy if some/one of you may be interested in making Kandela Lighting rise, the end of the rainbow is in line of sight <3
If you want to know more about all this, feel free to contact me here or via the discord.
May the light be with you
PS: Dont believe the crappy cam pics, the lights are “un-captureable” (7 out of 10 who see it wanna buy it
