Oh I'm on him 24/7 now. :)

Located why the psu didn't start yesterday. It was a short between two stripped calbles (+5v and -). So it was my fault. This psu have been part of many projects before this one. Should have looked over every cable before using it....

Of course in a perfect world. The more water you pore in to it the more can go wrong if you have any leaks.

get a big radiator
Click to expand...

I have shortage of cold air for cooling. I really need to make magic with the degrees difference I got. This project started with the heat wave we were having this summer. Stopped growing when my intake temp was 32C and exhaust temp was 37-38C. In that situation it's impossible to cool anything with just air. That's why the peltier. More effective cooling with low cost against an Ac eating away Kw's...

Also consider about making 1 big cooler for all the LED's with some proper channels and flow system (in and out) - that would increase the cooling alot more

Made the blocks with what I had laying around. The bottom is made with brass plates from hatches, the rest reused 5mm acrylic sheets. Have no means of milling channels in them proper. The way they are set up now I can easy rearrange how they are positioned. The Idea was to have them in a 120cm wide tent but I had no room for that tent this run, so now It was very easy to build a smaller frame and reposition them for a 60cm wide tent.

Always make it as save as possible ;)

Sure - the problem is always leaking - but if u build it right - it should last for ages ;) (making a pressure test would be a good idea)

I know what u mean, this summer was very warm at all - but I also think a big radiator with active cooling would also be enough at 35-40°C airtemp - it's better to cool them just with air - in this case it wouldn't be enough.

That why I also consider about cooling my LED's with water...next summer is coming and because of the tent is in my wardrobe, it get's extra hot - now in winter it's not bad...

on with page are some pic's of them? couldn't find these :(

Don't know... they are back there some where... ;)

This is how they look...

Brass plate with acrylic sheets sandwiched welded with epoxy.

This is where the leak originated. The heat buildup cracked the acrylic round the connectors, there was probably tension in the sheet and the heat made it expand and had no where to go...

As u said, looks awesome - very custom :D and yeah, there is always something that could went wrong, especially if u build something for the first time ;)
 
CraZysWeeD said:
Yeah, I'm glad I spot the leak in time and that the light took no damage of it. Always good to have backup and spare parts.

U should drill the holes a bit bigger - OR u use metric connectors like these:

temp748_2zn7O4KMtoH0jO.jpg


they have:
  • Thread: M10x1,25
  • Material: Aluminium
  • Connetor: 10mm
one would cost ~6€ - than u could cut own good threads ;)
 
Teleon said:
It would be also a good idea to use an Arduino to protect from things like the pump is not running or something else.

U could also use it for collecting data like Temp / Humidity / waterflow / watertemp / led temp....and so on .... :D

Might be cool to control everything by a little microcontroller ;)

That's been the idea all along. But been so busy getting the cooling running it's eaten all my effort and energy the last two months now.
 
We are sinking, what are you sinking about...?

The added insulation against the radiator was a success. This forces the air through the radiator. Swapped the heat sink today as well. The system temp is now at 30C this is after 4 hours of running was at 39C the other day. So that new heat sink is more effective than the bigger one I had before. All this is one step closer to connecting the tent vent through Poseidon.

White Widow have grown much the few days, those new tops are going to take off soon. Pruning next weekend.

Spliff Berry is more layed back. I hope the beat up side shoot is getting through the abuse I gave her. Sorry honey, it's for your own good.

Yeah, I would say it's hard getting under that. The photon heat is impossible to get rid of completely. Sure you can shield it of with glass but then you loose photons in the process...

But now I'm more confident in Poseidons capabilities, I'm sure I soon start expanding him. :) @Teleon lifted the old thread with my 6040 A1 cobs, maybe should throw in a few of those in the mix. :)

U should do this ;)

And I edited my post, anyway to late :D I think when u use a bigger radiator the temps would also be good in summer, without the peltier!
 
Teleon said:
No, actually i hate them :D

It would also be an advantage when u put a little 12cm fan on the radiator - just for testing ;)

Tomorrow I'll tinker a bit with my Arduino - want to make a "weatherstation" for the tent, with wifi that I can check the data from the pc ;)

Haha, what's up with that then? I know they can live their own life sometimes, you got to treat them right.

I have tested with a fan. I got to the conclusion that my duct fan was more powerful than any 120mm fan I could find. That's why I want to let the tent venting pass through Poseidon and the radiator. The fan I got sucks 800m3/h on full steam, running it on 110V right now so it should suck 400m3 now that should cover the radiator venting, right? ;)

Sounds fun, it's some time since I tinkered with Arduino. But I made an hall effect flow meter for work, measured ml/min. That's the most advanced I got with them. Would like to learn some wifi with them. Ever tried tinkering with Raspberry Pi?
