Ask Things, he has a laser cutter (I think its him at least)
My first Photino RGB is sort of a "trial run" and I'll probably bypass the ATTINY entirely and just go constant white. The first build is just whatever diodes I had laying around (a MITS 300, 9mm 445 and a PL520 B1). The MITS 300 looks horrible combined.Awesome! Always thrilled to hear any updates on this. I'm honored to be involved in such an auspicious build.
Remember, I'll help with any kinks in the programming or electronics should the need arise, just ask. =)
No, it's just going to be an on/off situation per channel (so, I'll get yellow, cyan, magenta, but nothing in between). In the driver thread, they didn't think it was possible to control PWM on three channels with an ATTiny.That's some incredibly detailed CNC work there.
This looks absolutely amazing and I can't wait 'till you finish it :beer:
+1 (btw, I meant to say 'sir' in the rep comment lol)
What kind of code for the attiny13a micro-controller have you based the firmware on? Or did you start from scratch?
When you implement the attiny13a into the final build will it individually address the PWM value for each diode or do you
have something else in mind? Also the voltage limit for the attiny13a is 5.5v so what sort of input voltage are you
working with for the green and blue diodes?
Maybe I've asked too many questions.
Yep, not enough GPIO channels on these 8pin chips to do on-chip PWM.No, it's just going to be an on/off situation per channel (so, I'll get yellow, cyan, magenta, but nothing in between). In the driver thread, they didn't think it was possible to control PWM on three channels with an ATTiny.
It was a scratch-built program. I still have no idea how to actually load it onto the chip. I have the chip, and the USB controller, but it's not as easy as the chip showing up as a USB drive and copying the program text
Just leakageWow! What is the light we see on the top? Just leakage from the inside, or is that strip illuminated independently?
