This will be the build thread for my newest project, its quite a ways off from firing up for the first time but I have the emitters ordered as of today and am working on the driver board and I already have the heatsink (solid copper) built and installed in the host and the reflector holes opened up for the SST-90's domes. The driver is a FET based driver ran by an ATTiny85 which at first will be supplied by DrJones and his FW till I'm able to write my own (also looking at the possibility of using a PIC MCU from tterev3 like used on his MLEV)
edit 8/7 new RGBW driver (not for this project) in post 101, an independent channel driver that takes a PIC MCU bought from tterev3 preloaded with his MELD UI.
Anyway dont expect daily or even weekly updates, just teasing you for now but I will update this thread as things progress.
I posted these same two pic's in the OSHpark thread, this is my first real project, could of choose something simple but nope, thats not my style, I go balls out!
So here you can see the DPAK FET, the MCU and the other components on the front of this 22mm board:
looks good right? But wait, whats that on the back side?
Its just two more FET's! Running the 3 SST-90's together in parallel would be bright sure but I could do that with an existing BLF driver, this one has independent channels for all the cool color mixing and other functionality both DrJones' and Everett's UI's are capable of. Any of the 3 channels can be ran at any level independent of the other channels, one, two or all 3 emitters can be on at any time and all 3 can be on for "white".
This will be my second RGB only (no white emitter) light and I'm really liking the idea, sure colors arn't true but its just to fun to matter plus strobe is much more effective than white only, you literally cant walk when having a 19khz RGB strobe blasted at your face (ask all my friends if you dont believe me, it literally makes you loose your sense of equilibrium). Last weekend we took my RGB light out to the river and shining it down at the ripples on the water while walking on the beach made it even worse, my one [albeit slightly inebriated] buddy went down in the water about 3 steps after turning the strobe on lol.
Anyway thats all for now, check back for updates and stuff but this is probably gonna be a few month project, customer orders come first especially over my "toy's". For you're guy's entertainment I'll try to get some pic's of the shiny heatsink and the host up today too.
