RGB Driver?

[Tyhm]

I'd love to save up to make an RGB saber (one that rotates colors with nauseating speed, leaving a multicolored blur in its path...because I'm weird, and love the Crissaegrim), but I don't think I'm really up to the challenge of making my own driver board for it...is one on the horizon? Or is it solidly the purview of the Truly Hardcore for the foreseeable future?

(Tried to search, but apparently "RGB" is too short a search string and so is ignored...lulz)

No one is developing one right now that flashes through at blinding speed. Most people like their sabers to remain on one color at a time, so I think you're for the most part on your own here.

Actually, Maul, I AM working on this. It's based on the Arduino Nano and Troy0's 4-channel LED driver. No sound planned unless the OSSC ends up being compatible or you use a separate card with a relay. Planned features:
3- or 4-color defined at 16 bit depth each with optional Clash-on-flash for the fourth channel.
Adjustable color rotation speed
"Prismayhem" mode that throws random color values, also adjustable.
If a good control method is established, manual static color definition can be a possibility.

Please note this is all in the planning stages and is a ways off.

Im curious as to what your doing different than using Troys driver (which he even says could be smaller and more efficient then the current....and in the future may re-design it).. its also only a DIY format that I know about currently..

and then an Arduino to PWM/shift through colors...yes?

sorry maybe you've expanded on this before.. but I dont see anything new/different?

thanks

If I can get a proof-of-concept I'll pitch it to the engineer gods here and elsewhere and see if someone wants to develop a purpose-built card, or I may try it myself. Right now it's just for me.
Edited to add: Right now there exist RGB drivers that scroll through colors but not at the speeds the OP is looking for, nor do they have randomizer features.

Are we likely to see these extant RGBs in the shop local someday? I'm curious why we don't have 'em...

I guess Im still a little 'unclear' (sorry)..


but wouldnt you just need to tweak thew code a bit? to even remove the button event(s) all together and do it on a timed cycle?

(again, all handle by a tweak in the Arduino code?)

so nothing much different than some array/pwm code changed in Troys demo?

[Darth_Dadderall]

I'm not sure what you're asking. AFAIK Troy's 4-channel driver doesn't have any control mechanism, it's got ports for PWM but doesn't do its own. I could be wrong about this though.

[xl97]

Troy has that driver schematic, yes..

but he has coupled it with an Arduino 'brain' and some code to 'cycle' through an array of colors in the RGB spectrum..

so I guess what Im 'asking', from your description.. what are you doing thats 'different'?
or 'furthering' what Troy has already done?

Tweaking the code for your Primayhem thingy?

thanks

[Darth_Dadderall]

I had forgotten that Troy had an Ard turning the wheels. My bad. This would be a continuation of that work, expanding and refining.
