It can be done ...
The Tc analog panel monitor gauges in reality have to be modified voltage meters ...

Then it will need a couple of Negative Coefficient thermistors of high precision (low tolerance) and a microcontroller (like arduino,for example ,although an overkill for this case ..) with only 2 analog inputs for the sensors and two analog outputs ( 0 to 5 V ) ,in order to display a temperature range ....
For example the temperature range of 25 -50 C can be mapped into the microcontroller ,to be an output analog voltage ranging from 0 to 5 volts ....That can drive an analog 5 V voltage meter ....Every volt shown is 5 C ,in that example ...
0=25 C ,1V=30 C , 2V=35 C ,3V=40C ,4V=45 C ,& 5V=50 C...
Print new panel graphics and units ..

Nice idea ...
Thanx ...
Maybe on another design of the "RETRO" series ...

Cheers.

Almost ready ,that part ...

PA011576.JPG
The active cooling core apart from actively cooling the heatsink fins ,serves also as a large radiator ...
All of it's surfaces contacting will have some sort of Thermal Interface between them .
( Epoxy-silicone or grease .) This also elimanates vibrations ,between the metal surfaces ...

This time air blows from top ,to exaust to the sides ...



PA011579.JPG

Epoxy is hardened to rock -solid ..Some sanding is needed there ,to level things ...

PA011578.JPG
The top lid (left) and the bottom (right) .
They are made from Steel sheet .
Those are the most tricky to cut holes / openings ...

Afterwards they need some light sanding..
Rust -proofing ..
And finally to be painted ...


And the case part of the project will be complete ....

Then the "electronics" part follows ...

Cheers .
 
Painting is done like that :

1) Lightly sanding of the pre-painted /rust-proofed surfaces .
2)Cleaning with acetone.
3) Preheat the surfaces to 50C ( into kithen's oven ....).
4 ) Spray the paint .
5) Place the freshly painted surfaces to oven ,at ~80C for 30 min .

Polymer paint carrier (the substrate ) usually acrylic or polymethylacrylate ,melts and bonds
.
After cooling down paint now is a strong film of polymer and not just particles of polymer bonded together ...

Cheers.
 
The next step is attaching the rigid bars to the inner lid ...
Some thermal conductive silicone there ...
PA011588.JPG



And attaching with two rivets per bar (one at each end of bar ) and tighten with the four screws per bar ,
until the silicone hardens ...
Excess silicone comes off ,to be cleaned later ,when hard ...
PA011592.JPG



This is one of the four "Noctua Anti-Vibration Mounts" ...
Made out of hard silicone .
Along with the silicone pads at the corners of the fan ,will
ensure a ' floating ' & 'cushioned ' mounting of the fan to the Active Cooling Core ..
'Enhancing ' the silence of it ...

crazy idea and more work with paint... but ...maybe stealth camouflage pattern with your colors... ...maybe sticker way?

...google images stealth camouflage for dessert...

..this is military style?...

Now ...This inner plate will bear also the two MeanWell HLP drivers ,at the sides of the fan ...
PA011594.JPG


The fan is firmly attached with the use of Anti-Vibration Mounts ..
Still It is "floating " and "cushy"..The vibrations of the fan passing to the plate ,are reduced greatly ..
Total silence ,I wish to fortell...

Up till now ....

Imagine if I had to build something like that with monos ....

Something like that :

monos .JPG

This light is a tad less than 150 Watt ...

http://www.agrospaceconference.com/wp-content/uploads/2014/06/Pres_ASC_2014_Dixon_s3_1.pdf

Somebody has to 'whistle' to these 'space age white collars " about CXAs or Veros ...

I think I've seen something like that ,back in the 80's when I was a boy ...
My parents must have taken me at a disco club ..Or it was a roller arena ?
Maybe it was a circus ,I think ...

The wiring alone has to be over 4 pounds ...
Quite more weight than the heatsink I'm using ..
Just the wiring ..

Sending 'pasta ala Copper ' to Mars ...

Circus ...

Cheers .

An interesting report no less. It's pretty cool to see how different colors of light or spectrums affect the growth and development of different varieties of vegetables. While the light unit they showcased looks chunky and boasts a low power output, it served their purposes, which were for research and analysis. It would be cool to see how different strains of marijuana hold to this kind of study, whether sativa and indica differ in their germination and vegetative states with similar or differing lights.

Great post rDustr ;-)
