Are your middle names mad professor by any chance?

Oh sweet JEBUS that is nice!

been watching mattā€™s videos the last 2 days and Iā€™ve got this, this is a 3ch RGB 22mm driver, itā€™s far from being ready to order, I just wanted to see it in purple.

One important aspect of this driver was for it to allow any of the connections from either side, thats whats with all the viaā€™s.

This will be driving red, blue and green SST-90ā€™s in a light Iā€™m building (Yes I know what they cost [$44/ea], go big or go home right!).

Bazing man!

Getting better all the timeā€¦pretty sweet board!

I know you've said its far from finished but my 2c:

1) pretty great layout as is, and it's nice to see you have followed my advice (maybe even intentionally lol) if using nice angled/rounded bends in traces. Not right angles in sight!

2) I'd finish the layout and then beef up as much as possible every trace you possibly can. Not crtical but I've found on very rare occasions that OHSPark can give dud traces if they are too thin.

3) Label everything. Components, wire points etc.

Other than that its a pretty darn good first attempt!!

Standing on the shoulders of giants :wink:

Redo #1. Youā€™s guyā€™s you should be proud I setup the LED leads on opposite sides of the board completely unintentionally.

After I submit the zip folder to oshpark and it gives me the first front and back render and I hit continue, where it takes you to the approval page with a different view of every file layer, is there any way to get back to that view later? Or is there a way to view the individual gerber files layer at a time?

noā€¦that is a one shot deal before it adds it to your projects tab

You can view the layers online though

This one generates a pretty cool little 3D view of your build (not in OSHPark colors though)

And there is gerbv for windows

Still missing too many parts to fire it up, but it's partially assembled to give you an idea of how it looks with and without optics, and in and out of the host. Most of the work is going to be creating a spacer block on top of the old LED board to help them new emitter PCB sit tight against the lens. Not too difficult, but important for heat sinking purposes as well.

If the back side is raw copper pour would you be able to possibly solder the entire thing to a 50mm copper round from etsy?

That is just too damn cool!

That could work, though I'm not sure how thick those rounds are?

20ga or .953 mm

I bought a stack of emā€¦about 1/2 as thick as a standard SRK aluminum star, not that thick but thicker than the microscopically thin copper pour that is on the PCB

Too damn cool indeed! Both Mataus build and Cereal Killers board!

I keep watching in awe!

Is it correct that at the moment no BLF20DD is available at Oshpark? (the link in the OP does not go anywhere anymore).

I would have liked to order one (=3) for a UF LZZ15 mod in the planning.

Thanks Werner!

You just need the one? I have one left I can stick in your package thatā€™s shipping this week so you arnt waiting for ever. let me know if you want it.

Too late, just ordered it, thanks for the offer though :beer: . I just today ordered the light it is going in so the Oshpark order will probably be in earlier than the host, so there's no hurry :-)

Yeah, the BLF direct drive drivers have been updated, the C1 has been relocated between the B+ and GND in order to eliminate the accidental boost effect of the cap and the diode when the power starts fluctuating/pulsing when the FET is turned off and on by the MCUā€¦these revisions should eliminate the issue with dodgy mode selection and have the buffer resistors removed completely, also added off time caps on star 4 pin. I tweaked them up and Mattaus has reviewed and reposted all of them, the OP hasnā€™t been updated yet (also reset the ā€œversion/revisionā€ number because they were getting squiffy)
