Cutter Electronics: Complete DIY COB kits
- Thread starter Growmau5
- Start date
I feel like an idiot. 80/20 has a 20mm series. Here is a bracket for attaching a wire panel that should work perfectly to attach one side of the heat sink to an 80/20 profile with two 10-24 machine screws and two 3mm machine screws. https://8020.net/shop/20-2493.html
Bosch and many other companies have a 20mm profile. I'll keep poking around for a better bracket.

Yes sorry about this, we had 120 heatsinks made to test this concept. I have another 150 ordered but likely to be mid to late April, so feel free to backorder, but thats the current leadtime
Thanks again for the support
Cheers

Mau5 is a mad scientist at work. Wish my dinning room table looked like that.
Mark and Mau5 looks like this is the driver for the kit right?

Can't wait to start piecing her together

Are you going to get in the bigger drivers with the new orders?
Nice. What is the star-shaped thing you're working on? Looks very interesting. Also LOL at the mom's basement bit....

It's worth mentioning that when it comes to CRI and the spectral charts, each curve is relative only to itself. A while back MrFlux did the computations to provide a look at the absolute values. Keep in mind this chart is for CXA, but the principal is the same.
Here is the thread if anyone is interested https://www.rollitup.org/t/cree-cxa-analysis.743645/

The kit can work with the 250 watt driver we are combining with it. What would you like from a bigger driver?
Cheers
Mark
No we are supplying the kit with the 250 watt version

I'm still working out the geometry and spacing, but it's an 8 axis light mover that runs off of a single stepper motor or dc motor. One more shot out of wood, then I'll cut it out of aluminum and show you guys how it works.

LED technology is new and evolving as we speak, this is a 200w light for 600 dollars. I want to build one for a 5x5' area badly! and will eventually but the damn cobs are expensive, and the heatsinks are to, i think? Last time I priced some 3070's, heatsinks, drivers, and etc came up to about $1000 dollars. That was how much I figure i need to best or get to my 1000w hps yields. But yeah they are expensive. To lazy to price each individual part and compare to see the mark up but six hundred dollars for two hundred watts is just to much IMO. I believe in 5-10 years we will be able to get these LED's at a much cheaper price. But they rock! Love seeing what guys here on RIU are doing. And I'd be lying if i said I wish I had the capital to start a light company selling LED's. Just got my Electronic Engineering degree so I'm up for the challenge, and incorporating arduinos in my grow room is in the works now. These things are awesome. They are so much cheaper than controllers and have more capabilities and are much more flexible. The code writing is the hardest part for me, but i get by and luckily there is alot of code already written out there and i copy and past real good.

oh thought is was 200, 4 cobs at 50w

They use the 250 so you could add an extra if you were so inclined. Id just buy 2 kits and 2 extra cobs and heatsinks and do a 3-4-3 spread.

not $600, under $450 USD
this video goes thru the pricing of components (1:30 in) from alternative suppliers. You pay a slight premium for this kit due to the labor involved in drilling and tapping all the holes so its read for mounting when it hits your doorstep.
Thanks for the great comment, I look forward to seeing your arduino works!

Do you guys have the supplies on hand if we just drill the heat sinks ourselves ?
I Like the whole kit being together so i know what driver and cob and heat sink and don't have to try an understand the numbers.
p.s Whats the difference between the 4 cob and the 8 cob kit do the prices include shipping.
Im asking because there is a $50 increase for buying the 8 cob kit where as buying two - 4 cob kits would save money ? Im lost.
P.S.S!! Is it possible to get the kits with a 700 mA driver or will it ever be possible in the future?
