Huh? That's what I said... let me try it this way.

What is the [what looks like an 0805 pad] marked 4 connected to MCU pin2?

Resistor at pin 2 is for the off-time 1uF/10v capacitor.

Also on this board where would the zener diode go?

Zener diode would go anywhere on the trace from the D1 pad (resistor instead of diode, on a zener-mod driver) and MCU pin 8. Most convenient would probably be to put it between one of the vias and to ground.

My mistake comfychair! You can’t correct someone who’s already right! You said it right, I read what you said wrong. I’ve really gotta slow down.

Still fine, still on a break. One day I’ll catch up with you folks! previous wight catchup Wink

Ah should’a figured that one, I’m literally right in the middle of learning eagle (since this time yesterday) so my brain is pretty taxed right now, thanks guys.

If you're using firmware other than the STAR off-time you can use the pads as jumpers (same thing, they're just bigger)... or as the switch connection for the momentary version.

(I did call it 'resistor' when referencing the pads, that's probably what did it) Smile

BLF15DD Version 1.0: https://oshpark.com/shared_projects/V4ua4iuK

I have removed ALL the old Direct Driver 15/17/20 drivers. I didn't even realize that I had been leaving old versions up. The only boards you will be able to get your hands on are the DD, DD-Z, and linear version 1.0 boards now.

Hey guys any of you US folks interested in getting in on a larger digikey order? I need to reup my own supply, I’m looking at ordering a few hundred resistors, 50 input cap’s and some 13A’s and AOD510’s, I’m probably going to place my order tomorrow, if anyone is interested in getting any of the standard 105c parts and/or FET’s please let me know ASAP and we can get it setup to get better prices.

Also getting some neutral XP-E2’s but the first level price break doesnt start till 50pcs (but still only $2.57/pc)

It looks like I’ll need to do some editing on the op. Family reunion has kept me pretty well occupied this week and flying home tomorrow. I’ve been checking in when I could but it didn’t seem like the dust had quite settled on some of the newest ideas. I’ll be working on editing over the weekend but if I miss something please let me know either here or by pm so I can get it squared away.

Yea like $5 but I’ll never use 1000 of them.

Also going to be ordering myself 5 105c’s from FT if anyone wants in on that we can email them for bulk rate.

Got these today. Looking forward to building one and seeing if it works. Definitely going to need to solder fill all those thermal vias...

I need to edit the image to make it a bit smaller...

Are you waiting for someone to ask what it is? Ok, what is it in really simple terms.

Matt,  I've been waiting to see that thing in action!

Mountain Electronics : batteries, Noctigon, and much more! What's new?

That’s one of the SRK drivers with all the parts visable from the lens?

It's a 'Medusa' replacement PCB for SRK lights. Fully integrated LED and driver. It was done more for shits 'n' giggles (will look 'mad wicked') than anything else but if it works then sweeeeet. Has a direct driven quad array with medium optic (hence why I asked for that quad optic), a single direct driven (albeit lower current) XP-E2 through an optic for throw (or whatever optic is chosen), and a single reflector with RGB XQ emitters for color mixing. If I ever revise the design I'll replace the direct driven XPE2 with an AMC7135 and a UV emitter probably.

I won't be able to fire it up until I get my MCU from tterev3 (on it's way) or my 4 nichia emitters...which I just realized I haven't ordered yet. Sh*t. I have everything else already so I'll start work on the host and beefing up the heat sink this weekend.

been watching matt’s videos the last 2 days and I’ve got this, this is a 3ch RGB 22mm driver, it’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 via’s.

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

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!!

Redo #1. You’s guy’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?

no…that is a one shot deal before it adds it to your projects tab

You can view the layers online though

http://www.gerber-viewer.com/

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 em…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!
