penny water cooler

thingiverse

Here's for all those like me who believe Arduinos (or Pi, or anything similar size) should not be left out of the loop when it comes to water cooling. One day my arduino got jealous of my desktop, and I just felt bad for the little guy, so I made him a waterblock! Now my Arduino feels like the coolest kid on the block again (so many puns). Obviously this is not necessary, but its cool in a geeky way. I'm not responsible for any damages this can cause in any way. As with all liquid cooling on computers, do this at your own risk, but have fun! I strongly recommend leak testing this for a while before installing and definitely use distilled water. I've most recently used this on the first ever water cooled tablet. Through all my Google searches, I haven't found another tablet that is really water cooled. I have overclocked the tablet, and even as the battery drains from full to dead in 20 minutes, it doesn't go above 60c, where it was normally around 90c @ stock. Actual picture to come, it looks awesome in real life. The other object is a L298N motor driver where I thought I might as well water cool that, since the base of my robot is literally a transmission radiator. As for people that want these parts, I say be creative, none of these are difficult, I am happy to provide the key (the waterblock), and I say to my fellow geeks, go crazy and have fun, its not so fun when you copy someone else, so make it truly unique, and make it yours! Be awesome and have a great day! Printer Settings: Printer Brand: RepRap Printer: prusa i3 (bowden) Rafts: Doesn't Matter Supports: No Resolution: .5mm nozzle Infill: 100% Notes: Print with flat face down. I use a brim to make sure the nozzle primes before it starts. Printed in ABS, but I'm sure anything else would work fine. Assembly: print sand penny shiny and flat (I used a sandstone made for sharpening knives, bought at dollar tree) either put a very small amount of sealant on the edge of the penny, or just go for it and go to next step push in penny, it should be impossible to do with your thumb, its designed to tap in with a small hammer (to make sure it never comes out on accident, and seals well). push 1/4 hoses in (I used 1/4" hosing from Lowes, its $0.16 per foot), push hard, you may have to use a 7/32" drill bit (you want a snug fit, otherwise you will have to use sealant on the hoses) hook up a pump (I use a small pump, I got it on ebay for around $2.50, and can be ran off any 5-12V power supply) make a reservoir (I used an empty drink can, but a bottle with 2 holes drilled in the top is less likely to spill) and insert hoses Test it! run it for as long as you want to make sure it doesn't leek, if it does, put sealant around wherever it is leaking, unless its the walls, then its not printing right. Mount to device, for me, I originally just used a rubber band to strap it to the Arduino, but zip ties are commonly used in computer builds. Have FUN! That's what this is all about. Show it off to your friends, put it in an LED frame, have a cool desktop centerpiece, use it as you like. Notes: For sealant, I used a glue stick to just barely coat the outside edges of the penny, obviously washable glue stick is not the ideal choice, but i didn't find anything else within reaching distance. Use an old penny (those are the highest % in copper, like 1960's) *update, use a silicone based sealant for the penny, and if your tubes leak from being pulled to the side heavily, use hot glue to help hold them in place, so far my tablet has been running great like this. If anybody wants a video of it running, let me know, its pretty anticlimactic with nothing leaking, other than the pump is shoving water through the 11 ft of hose because I didn't feel like cutting any of it to size. Update, using green dyed water in my tablet that I just uploaded pics of make it look awesome! I may upload a video if someone wants to see it.
