LED PCB

[dantimdad]

@Matt Carden I have same arrays saved I found on ebay that are about $20 cheaper than the ones on that site,some with all the "saltwater" arrays they sell also. I want to say they have a store front on ebay.

I admit,you are right Nanobox,BlueAcro,Steves,LedGroupBuy all have nice arrays but it would be a fun project you have to admit. I also love to tinker so it would be fun.

That is why I do it. Unless it gets to be a ridiculous price, I would rather build.

I have had someone say I DIY or mod because I can't afford it. Poppycock. I do it because it's fun and a challenge.

Telling me I couldn't do my 93 cube for under a grand was one of those "Hold my beer and watch this" moments.

LOL!

No @Katrina and @Flippers4pups I don't drink. It's a figure of speech. I am watching my health I promise.

These Noopsyche lights seem to be unbeatable especially for the price. Unless like @dantimdad said you like to tinker.

I won one in a drawing. It works very well. I admit.

For the cost, it's hard to justify DIY. The only thing I would change about it is less white and 470nm leds and more RB/violet and add a mint. Also a diffuser. They have a winner already for most people once they get the instructions cleared up.

The thing even looks good and has a nice mount.

I am already working on a diffuser holder in TinkerCAD for it.

I don't like taking away from smaller companies like the ones I named in my last post,because all of them are amazing and I have used all of the companies in the past.

But there is no better feeling than looking at my tank saying,I built this light,I did it all and works amazing. That's why I love tinkering.

Yeah, I got my DIY light over my little cube dialed in night before last. I am sure the boys are sick of hearing me say "Look at that!" ;Hilarious

All I can hear is "oh would you look at that just looook at it" lol. Isn't it a good feeling ? Its like when you have your first kid lol just a good feeling.

Technically speaking, weren't my kids DIY too?

 

[Steven Garland]

So with this pcb,can you use any diode or no ?

 

[Steven Garland]

Absolutely lol.

Not unless they look a lot like the milk man. ;Hilarious

Nope they look like me... poor things. ;Wideyed

this takes 3535 diodes, a fairly "common" size but not standard. Luxeon doesn't use it for most of there diodes your having in mind. you can build out a nice array based arround cree and semiled diodes. something like this would be pretty nice:

Channel 1 4x Cree RB
Channel 2 Semiled UVs: 1x395 1x410 2x420nm
Channel 3 3xCree RB 1x Cree 470nm
Channel 4 4x Cree RB
Channel 5 2x Cree Cool White, 1x Warm white 1xCyan 1xRB

maybe add a bit more violet in, but that would be a really solid setup.

That really wouldn't be a bad array at all. When I get home I'm gonna add everything up and see how much it would cost.

I might just tackle one of these for fun. Could be an interesting project for the weekends. I do wish they sold the diodes also....would save me shopping around in different locations.

Somebody said hotplate, the kind u plug in for cooking. May be easier to control the temperature?

The hot plate / skillet works pretty well for stuff on a metal core PCB, for prototyping. Its easy to see when everything reflowed, and the thermal ramp is fine for most cases (just crank the knob to max temp, and watch for 5 minutes).

Yup, Cree XP-G/G2/G3 footprints fit on most of the 3.3/3.5mm footprints, as does SemiLED and Viosys.

 

[JDowns]

I take that back. If you go with the board @dantimdad noted.... They do allow you to contact them and do a custom LED selection for $40. Pick your own 25 diodes.

@theatrus builds the Blueacro. I would prefer to pay him the extra $20 than some board made in China. His PCBs may be made in China but he reflows these in house.

I use China for prototyping (... you can't beat the cost), but move to a US manufacturer for the metal PCBs once I have something nailed down. The thermal performance of the US brand-name metal core materials is a lot better than the Chinese budget stuff (though you could get it made there as well).
