Mineral Oil - Raspberry Pi

Tue Nov 13, 2012 6:42 pm

Hello Everyone,

A few years ago i've tried this with a huge aquarium, but it failed and it failed hard, if i'm not mistaken there where almost 50 liters of mineral oil on the floor because we had a leak overnight. But a few days ago, when i was trying to think up a case for my Raspberry Pi, i thought maybe i can build the same only smaller..

So i went to the local garden store and bought a Fish "farm" aquarium (1 Liter), one air pump and some aquarium decoration, cost me just $30,- or something like it.

After that i installed SqueezePlug and enabled AirPlay.. Tested it for a few hours and then placed it all it the aquarium.

I will now let it run for a week or two and hope it will run as it should. Also i need to wait 2 weeks for the rest of my stuff arrives like a 90 degrees HDMI adapter, LCD Screen 16x2 and a few more things. I Hope that i can fit the LCD screen in the aquarium and display the song which is playing trough AirPlay.

Let me know what you think i can / should do with the Raspberry Pi and the aquarium. :D

I think it looks great ... But hopefully no school kids will be inspired to see if it looks even better with real fish in the classroom!

It can be an option... =) But for anyone who is interested.. i ran this command to see the temperature of the raspberry pi..

[email protected]:~# /opt/vc/bin/vcgencmd measure_temp
temp=23.9'C


I don't know what the default running temp is of a raspberry pi with SqueezePlug, but i notice when RaspBMC was idle the temp was around 50.0 C

you could always make solar powered mini robots for the tank if you want some kind of activity in the tank. I would love to do this but would first need to extend the SD card out of the tank so i don't need to ever take the rpi out of the oil. Do they make SD extension cables or would I need to make one myself?

Really? Google is your friend. Do a search for "sd extension cable" and you will be overwhelmed with places begging to sell them to you.

Hi my "real name" is Austin, sorry cant give out last name becasue of goverment protection 8-) 8-) :| 8-) 8-) , but besides the point, I am a freshman at Las Vegas Academy for performing arts and international studies, YES, the REAL SIN CITY!!! :) I am very interested in purchasing 1 or more raspberry pi's. I was espeacially interested in this mineral oil rasp. pi postings. To my knowledge, mineral oil doesn't conduct electricity, but my real question is, can this setup be made into a portable system? i have drawn a CAD drawing of my future system. i was wondering, can 2 rasp. pi's be connected together to allow for a combined amount of ram, processor speed, and graphics? i am buying a 10 in touch screen, a 3 port usb adapter, and a big enough flat battery pack to power all this. plus, im liquid sealing my home built tablet case to allow for mineral oil cooling. Any major suggestions that may help me? :?:

Only if you consider an aquarium to be portable

Apart from saying cooling the Pi isn't normally necessary, and mineral oil isn't necessarily the best way to do it, do whatever ticks your boxes.
The forum is full of good ideas. Also bad ideas, zany ideas, and ideas that don't fit in any catagory. It'll take you a while to find your way around, but keep looking

Battery size is difficult. It depends on how long you want it to run, and what the screen takes, what the usb hub is feeding, ...
Lots of threads around on this, with lots of answers.

Overclocking: again lots of threads. You'll maybe get 1GHz from the arm, and varying amounts out of the GPU, depending on over-volting the cores.
They say you still don't need cooling, but it can't hurt, and can be fun. My feeling is mineral oil won't cool much, because the chip is under the memory, and because the oil is too viscous to convect much. But who cares? Try it!

TRULY I cant tell you, this always happens on any forum, but yea, i have read up on the ramble and Beowulf posts, i have ordered 4 raspberry pi's, and im buying micro heat sinks for each of the CPU's and GPU's, i have gotten the cad drawing done for the tablet case, but im looking at buying a 4000mah or 4500mah battery pack to power all of these, im hoping i can get it all together and mineral oil cool it, thanks for all the help

Some mineral oils have additives to make them conductive to prevent static electricity build up. Some have solvents to prevent dirt build up. Best be sure just what is added before you dunk your RPi lest it goes all soggy and falls in half like a biscuit in tea.

Oil is used for cooling transformers so its not all bad, maybe a link or reference to a grade that is safe would help.

What kind of radiator are you using on this to dump any heat accumulated?

It doesn't heat up that much with my experience, stayed a nice 27 degrees Celsius
