LED PCB's / Housing? For Excited Lamp Builds.

[kcarring]

I'm curious as to what approach to take here...

Today I wound up a SEC Exciter / Joule thief circuit and had some pretty good success. 40 LED's on 3v.

I want to house banks of 40 REDS / 40 BLUES. Grow spectrum.

When it comes to making PCB's is there a preferred method, or.. has anyone seen empty housings for this? Or something suitable. All I have seen so far is methods for making PCB's using an inkjet printer? Are there companies who'll do up a hundred PCB's for you if you give them a CAD file?

I know I can buy banks of many LED's.. retail LED grow lights, but they are kind of expensive. 20,000 MCD LEDS are quite cheap now. I want to run banks alongside coils and have them run off occasionally energized caps. And the odd wireless location for troubled plants to get an extra light.

When I've completed experimentation though, it'd be nice to house this stuff and get it running in the greenhouse in spring - go from the breadboard to a salad on my dinner plate with this stuff. Personally I'd rather experiment in a greenhouse first, in case all that EMF is bad for you, as opposed to having excited lighting in my living areas.

Thanks

Hello Kyle,

Yes there is a company called Express PCB. They have a site where you can download the software to design your own PCB and then send the design to them and they will give you a quote to make as many as you want. They are mentioned somewhere in a couple of posts on this forum and you can also find them by just doing a search with your favorite search engine. I still haven't figured out how to attach links to a post on this forum. Hope this helps.

Hi Guys, Here's a link below, Happy growing, I wonder though if the plants will like your exciter. It will be interesting to find out it, might enhance them with the energy. I wonder about the radiated energy aswell, being bad I mean but somehow I don't think it is all that bad, some people are sensitive to it I suppose and it may be harmfull to some and not other's.

Carroll posting a link is easier than I though it was originally. All you need do is go to the page, copy the whole web address and paste it into the post, but there needs to be a space in front of and at the end of the address, when you hit the preview post button you see it as a link, it's done automatically.

The space is what confounded me for a while. It ws a real revelation when I worked that one out.

Thanks for the link! Yeah, I don't know either. I don't see them doing any shielding of coils in typical compact CFL's (AC ones).

I've spent so many years exposed to EMF's while falling trees near power lines, and have received 15,000 substantial "static discharges" from the hook, under a chopper, helicopter logging... that I kind of doubt this stuff will finish me off. I am though, concerned about my little girl and her health. I am exploring the use of magnets and helical spiralled valves for watering irrigation systems too, lot's of people claim it all helps.

You could just draft it out on paper with a pencil and ruler then felt tip pen then make the pcb yourself:

Thank-you very much, that's great info!

excited lamps

The typical 20k white led forward voltage is 3.4V
try not to hook up in parallel as significantly wastes battery.

lets say you want to use 10 leds.
3.4V * 10 = 34 Volts (series)

it is much better not have resistors.
But you can take a 12V route and have some paralell nothings perfect.
parallel meaning a resistor on each string.

Keeping the frequency under 500kHz will not offend others
as it is illegal to broadcast spurious noise. We can later recycle the noise.
I just accept the law and work around it, I call myself mikrovolt for that reason that as a prisoner of controlled power I am free at low power.
I really can appreciate your post.

I hope the spatial coherent people keep going with their study as we really need to understand any ZP extraction process.

Well,PCB indicator featuring a standard intensity, diffused LED element in a range of colors and voltages. Reverse polarity options are also available.Without pcb files, the client only making PCB LED output files containing PCBs and PCB-producing LEDs.
