Putting 300 Watts Of LEDs On An RC Plane

September 7, 2012 by 35 Comments

Being a member of the FPVlab forums, [HugeOne] is really in to strapping a video camera to RC airplanes and flying around by the seat of his pants. He’s also in to flying his plane at night. Combine these two interests, and you’ve got 300 watts of LEDs flying around at night, most likely causing a spike in UFO reports in [HugeOne]’s native Quebec.

The main issue with putting 16 CREE XM-L LEDs in such a confined space is the issue of heat; even though these LEDs are amazingly efficient, they still produce a good amount of heat. [HugeOne] solved this problem by soldering these LEDs to a piece of copper pipe and connecting two radiators to his plane for liquid cooling.

The result is a small, lightweight LED array capable of producing more than 20,000 lumens flying around the wilds of Quebec. This greatly improves [HugeOne]’s night flying ability (video after the break), and has surely annoyed the local police department with an increase in UFO reports.

Does anyone know how bright the nav and landing lights on single-engine passenger airplanes are?

Keeping Axolotl Healthy And Cool

December 21, 2011 by 44 Comments

The real life Mudkip Wooper Pokemon seen above is an axolotl, a salamander-like animal that lives in only one lake near Mexico City. These adorable animals can be bred in captivity, but keeping them is a challenge. [LRVICK] decided he didn’t want to throw down hundreds of dollars for an aquarium cooler so he built his own out of parts usually used for keeping computers nice and cold.

Commercial aquarium coolers that would meet the requirements start around $300 and go up from there. Not wanting to spend that much, [LRVICK] found a 77 Watt Peltier cooler for $5 and figured he could make it work. Off-the-shelf parts for water cooling CPUs were used to construct the aquarium cooler – a water block on the cold side, a huge heat sink and fan for the hot side, and a bunch of tubing goes up to the tank.

Now [LRVICK] has an axolotl housed in a very professional-looking aquarium that is a steady 65 degrees. He’s got a very nice build, and the axolotl looks very happy.

My Desk IS My Computer Case

May 26, 2011 by 39 Comments

If you think that your water cooled rig is pretty sweet, check out this creation by Dutch PC enthusiast [Peter Brands] (Google Translation).

With his computer tweaked as far as he could imagine, he decided to spruce up his office a bit. In the process, he ended up tweaking his computer just a little bit more. After seeing a build put together by another computer enthusiast, he set off to construct a desk in which he could show off his computer. He spent some time drawing up plans with Google Sketchup and with the help of a friendly neighbor, started construction of his desk/PC case.

The desk is constructed from 3mm thick aluminum, and houses most of his computer’s components under a thick piece of glass. The only portion of the computer that is not enclosed in the desk is the 9-fan radiator he used for his water cooling setup. That part resides in his crawl space, which he connects to his PC via a pair of large water hoses he punched through his tile floor. If you are interested, you can see all 800+ pictures of the build here.

Simply awesome!

Update: Foundation PC Cooling

August 31, 2009 by 30 Comments

coolupdate

[gigs], whose foundation-based PC cooling project we covered earlier, has posted his initial test results. There was a large debate going back and forth in the comments as to whether or not this would work, and hopefully this should clear most of it up. He used a 150W fish tank heater to simulated his system’s heat output, and used a quiet fish tank pump to keep the water flowing. Over 8 hours, he was able to maintain a constant temperature 16° C (61° F). While not quite frigid, this would definitely provide ample cooling for normal operation with some headroom for overclocking.

Chart of results after the jump.

[thanks to gigs for getting back with real data so soon]

Foundation Cooling

Foundation with Copper

Overclockers are always trying to come up with new, colder, and quieter ways to keep their PCs cool. [gigs] was so dedicated to this, he decided to lay 6 meters of copper pipe to use as a radiator in his new house’s foundation. As of now, the foundation is laid (copper pipes and all), and the forum posts come complete with finished slab pics, though there is no house to speak of yet.

UberBong: Evaporative PC Cooling, Probably

October 16, 2008 by 24 Comments

We’re not 100% sure what exactly is going on here. It appears to be a massive evaporative cooling rig for a computer, though the title has us wondering if it doesn’t have any other uses. There isn’t much of a description, but we felt the sheer magnitude of this cooling system warranted some publicity. Some digging around shows that this was out in 2003, but it is new to us.
