Here I give you a little sneak peek of the next-gen electronic of the stellar constellations, Sethaa and me will sell at Eurofurence Art Show this year.
Well, because I'm only responsible of the elctronics, I can only show you "my" part of the new stellar pics , sorry guys.
The picture shows the first functional prototype of the new generation of the electronic. It contains a microprocessor, battery management, and a lot of LED-current sources of course. The LEDs and Wires are part of a quick an dirty test setup and will not be part of the final version.
Self-Designed and engineered layout, self produced and assembled PCB.
Build in 0603, TQFP, SSOP...
PCB is 50x50 mm.
Last year, the electronic in the offered stellar constellations "just" keept the LEDs bright, even thru the discharging batteries. And informs the owner of empty batteries.
This year, besides that, one or another function will complete the pleasure of owning one of our stellar constellation pieces.
so, you will get
- more functions
- more bright
- more LEDs
- more everything :D
(feel free to ask further questions)

Look at the Stellar Constellations Sethaa uploaded last year :) this is the controller, which controlles the current thru every LED behind the frame. This updated version is capable of controlling each individual current. So it is not that far to think about the possibilities which are useful in a stellar constellation, isn't it? :)
My compliments for building this thing from the ground up yourself.
Indeed a nice piece of technology, having one right here.
(I kinda work in the same business)
Did you do the programming yourself?
And any plans for adding a light sensor and movement sensor to the system?
Me has currently a system in the hallway that does the same thing for taking a walk at night, kinda thinking it may works for the artworks as well.

Having one right here mean: you purchased one of our starlit constellations on EF? :)
Yes, I designed, build (etching, drilling, assemble) and programmed it by myself. The code is written in ASM and C (depending on the criticality of the timing of each part of the code).
The shown design is Rev.A, a few starlit const. were equipped with Rev.B, where I changed the LED-drivers a little bit.
Yes, there are further plans with this design (light-detect / movement / radiocontrol / touch...) but that will be classified until next year MMC / EF or on demand. We will open up starlit constellation commissions later this year, when the commissioner can choose from different functions :)
actually this design provides 32 PWM-controlled current-sources for LEDs and a whole batterie management (compensate the current draw of the LEDs thru the discharge cycle, batt-empty-detection and so on), batt charging (NiCd, NiMH, LiIon and LiPO). I implemented 3 modes, two of them use a random seed to choose one of the LEDs and provide a random luminance to them, so that a sparcle-effect is build up of the starlits.
nice idea by the way to use it as a nightlight in the hallway :) how do you mananged the movement-detection?

most of what you said goes beyond me. (but indeed, I got the werewolf)
Cleary you do understand a thing or two of what you are doing, I just know a little bit of C and that's it.
I love the way you also build in those unseen things like battery check and different modes to choose from.
You must be a engineer or embedded electronics master.
The hallway lights (although I made a custom LED light for it)
The control is being done by a simple Infrared detector you can buy for garden lamps.
(didn't want to reinvent the wheel again for such a simple project)
Keep up the good there ^^
