  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

How about a third party company making and selling something to keep the RED cool in very hot sunny days? Seems most who have this are macguyver type DPs who make their own water based or ice packs systems :cold:
 
First Help is a nice big robust umbrella rigged on a c-stand.... :)
This helps also if the sun is not shining sometimes.... :)

I believe thats because photons cause warming as much, if not more, than sunlight does, on a global scale anyway, so in theory only daylight is needed for warming. An israeli scientistit noticed this not so long ago. Cosmic rays also contribute hugely to the amount of energy hitting the earth, which can vary quite a bit. A relative of mine, whos also an electrical consultant, recently said he tested some used solar panels, that another relative salvaged from the disposal company he runs. When directed towards bright sunlight they produced 13v, when turned the opposite direction, away from the sun, still 12v. Not a lot in it. Beware the ambient light!
 
I replaced one of the 1/4-20 screws on the rear of the top handle with a 5/8" spud that had a long 1/4-20 screw on one end. I mount an adjustable umbrella holder on the spud and attach a small umbrella to it. Works pretty well.

I presume you're joking, but for anyone who isn't in on the joke: Power = Voltage * Current. Both the current and the power from the solar panels will drop off rapidly as they are pointed away from the sun. Because solar cells are diodes they have about 0.6 V across each cell even with tiny currents generated from ambient scattered light, but you won't get much power from that.
 
Cooling solutions needed Red Team!

Cooling solutions needed Red Team!

Is there any real RED One Cooling solutions available?

In India, we find the RED One heats up faster based on our climatic conditions.

Its better to get answers from Red Team and any accessories maker.
 
How hot is "hot" over there?
I asked the question a while ago if camera was tested in higher temperatures and the answer was; yes. Shuts down at about 46 Celsius (if I remember) with a warning at 41. Can YOU work in those temperatures? An umbrela and a fan would help (of course) but the real solution should remove the heat from inside out (I think).
 
I am currently testing options for a low-cost cooling system. I will post the results here ASAP. I won't be offering it for sale, you will be able to DIY. Initial results look very promising. I get that Red users need this solution like yesterday. I'm sure Brian's solution will probably be more elegant and I can't wait to see it.

Dan,
In Austin this summer we've had about 40 days over 100 degrees (38C), so it doesn't take long for the ambient temp to reach 105. We work in these temperatures regularly. The camera needs some sort of heat-sink to pull the heat away from the body or even a peltier system (which would require power but could be very useful.)
The real solution is probably in a redesign of the camera with better air intakes and heatsink fins on top but I doubt that that will happen.
Whoever comes up with a solution will certainly sell quite a few of the devices (at least to red owners in hot climes).
Regards,
Shane.

We run into al kinds of issues with heat here in Phoenix. We keep the camera in shade and next to fans, etc as much as possible, but we're over 110* on average, and often over 120*... So it's a problem! I'm definitely looking forward to a cooling device!
 
I just found someone asking about undewater housings (or at least splash proof) and the same issue (heat) popped to my mind. In a housing of some sort, air vent is very limited and the temp could raise fast. If heat does not move fast enough from CPU's and other "internal organs" of the beast into the water, the limmited amount of air surrounding the camera will conduct the heat at its worse. If shooting on land (hot days and/or geographic zones) or underwater (in a housing) I think the need for a technical solution to adress those instances is obvious, but that requires intimate knowledge of camera's inside. Only the R&D team can do that. I don't believe any outside solutions will be good enough (3rd party coolers) in the long run.
It almost looks like a nice car/powerfull engine with a small radiator (or just aquarium tubes instead of propper pipes). Let's keep in mind the "up-gradeability" of the sensor, etc. The cooling needs to be ahead the upgrades (I think).
My (tux deductible) 2c.
 
We also have to prepair a shoot on a rafting boat.... so we need to mount the cam in scuba cam housing or something similiar... also here the question if somebody has experience in using the housing and heat....

any advice would be great...

thx
 
The top of the camera gets quite hot so I assume a cold pack tucked in there would do some real good. I keep gel packs in a soft-side cooler on my magliner when I am working the set as AC/DIT. Wrap them in a shop towel with one layer between camera/pack and more layers above. I might drape a shop towel over the top and sides as well to absorb any stray condensation.

As Shane notes, it gets pretty hot in Austin. Here's a couple shots from inside a pottery shop's shed. It hit 110F in there at one point. The shoot was MOS so we were able to keep the RED One fans spinning on HOT. The camera only started complaining at the very end while the DP was picking up some b-roll.

1st ac, Robert Rendon pulls focus while grip, Buzz Malloy handles the dolly move.
