$5 DIY Portable Aquarium




Introduction: $5 DIY Portable Aquarium

About: Hi, I'm Christopher Sales. I'm now 17 and a hobbyist. I started making things with cardboard at 4, lego at 8, weapons at 9, mechanisms at 12, and electronics at 13. I love making weapons of self-defense, and o…

Hi there! I love aquariums. Seeing those lights with plants, structures and of course, fish in them brings out the inner-child in me. But have you ever wanted to bring an aquarium that you can display almost anywhere? I'm showing you how to build a small, and portable aquarium for under $5!
Please vote for this ible if you liked it. Thank you!

Step 1: Materials:

You'll need a few things to make this. They can be found in any local store or you can also salvage parts!:
-A small, portable terrarium
-A small, dc water pump(I made mine)
-A translucent tube, or a straw
-Aquarium aesthetics
-9v Battery
-9v Battery clip
- A slide switch
-Soldering equipment
-Glue gun
-Electrical tape
-Soldering hands(Optional)
-Soldering skills

Step 2: Making Measurements for the Lamp

The top cover of the terrarium is what we will work on mostly. For now, keep the tank part. Do some measurement on it for the lamp. My cover was about 4.5".

Step 3: DIY UV Lamp

I cut this translucent tubing I found to 4.5". I sanded the edge a bit to smoothen it. I then soldered three UV LEDs in parallel in a linear position. I did it in parallel for the distribution of current to be equal. I finished it up by inserting the lights in the tube, soldering wires to both ends, and then adding a heatshrink tube. That's done!

I simply ran the wires through a hole on the cover. I glued it a bit and set it in place.

Step 4: The Water Pump

My pump is DIY, but don't worry because you can find lots of instructions online on how to make it. This ible by XDleader555 helped me make mine: https://m.instructables.com/id/Water-pump/
It needs at least 6 volts to work.
I ran some wires through the top and glued the pump in place.

Step 5: Adding the Power Supply

I used a 9 volt battery to power up mine for my motor needed at least 6v to work, and my LEDs 20 mA to light up.

I soldered the negative wire of the motor with that of the lights' and the battery clip.

I soldered the switch to the positive wire, glued the wires and battery to the cover, covered with tape and that's done.

Step 6: Adding Some Designs to the Tank

In this part, we will be using the tank. I glued a small plastic plant from one of my tanks at home, and taped a background display on the back. You can add more, just not too much, because it has to be light since it has to be portable.

Step 7: Fill the Tank and You're Done!

I filled my tank until it reached the half of the pump so it can pump the water in and not touch the lights.
I loved how my tank turned out in the end. It took me just 3 hours to finish it,including the time it took to make the pump. You can bring this fella anywhere as long as you're not too shaky.
