Coffee Pot Fish Tank

Recommended Posts

My girlfriend wanted a Betta fish for Valentine's Day. When we got it home, I realized that it was a Tropical fish needing warm water - a slight problem in the winter. Using a coffee pot and the MSP430, I hacked together a (I think) pretty cool fish tank that not only looks good, but keep the little guy at a happy 75-80 degrees. Rather than rewrite everything, I am just going to link to my web page - I hope that is ok?

Nice and easy. Is the blue color ok for the fish?

wow 80 degrees and it's still alive? i thought they only survived in water that was around 30 degrees.

 

I think you are thinking in Celsius :) While I do prefer metrics for woodworking, here in the States we're kinda used to Fahrenheit. lol

A 4 degree temperature swing is quite a bit for fish.  You should see if you can implement a PID loop to PWM the heater element to keep it within +/- 1 degree at all times.

 

That is a good idea... I may try that this summer when the heater won't be as necessary.

THANK YOU! I am glad you guys here like this. I have never seen so much condemnation over a fish tank in all my life! (via HaD)

 

Don't take them too seriously, some people get uppity over the dumbest things... :-P  Good job on the coffee pot :)

Man, I had to go back and look at the HaD comments after seeing this post. Your tank looks like a much better environment for your beta than any other I've seen in a store. They're acting like you built a sous vide rig for a daily beta snack. Ridiculous.

Just think - those comments are WITH moderation.  Before they added that - they were way worse.

BUT - if you do decide to sous vide some beta fish - you totally could!
