DIY Betta (or Any Fish) Tank With USB LED Lamp
My first Instructable.
I found a cute candy jar being sold here in KSA that looks good for a Betta tank. The USB powered LED lamp feature was originally from Artificial Intelligence (https://www.instructables.com/id/The-USB-powered-LED-CD-lamp/?ALLSTEPS).
It's USB powered because this Instructable would look good on an office table, and you could always be with your precious Betta (or any other fish) at work.

Cleaning and Gathering Materials
Cleaning:
1. Eat the chocolates/candies.
2. Place your jar in a pail of water until the label is soft for you to remove without scratching the jar.
3. Dry it with a soft cloth.
Materials:
1. soldering iron and lead
2. electric drill with 5mm bit
3. 7 LEDs
4. 7 resistors - 68 Ohms
5. hook-up wires (solid)
6. switch (optional)
7. USB cable (from a broken mouse)
8. 2 CD slim cases
9. mounting tape
10. rubber footing (don't know what it is called exactly, but these are the rubber footings from small equipments. i got mine free from a network hub)
11. candy jar of course (any type is fine, just use your creativity)
12. super glue
Rubber Footing
Peel off the rubber footing and stick them under your jar. This will prevent slipping and make it stable.
Mounting Tape / Double-sided Tape
Stick about an inch of mounting tape inside the CD case, but don't peel the other end just yet. This would lock the two sides in place to hold and protect your circuit later on.
Then stick some mounting tape of the same length on the outside so that you could install the CD cases on the roof of your jar.

Installing LEDs on the Slim CD Cases
Choose the location for the LEDs.
Use the electric drill and do some holes on your preferred location.
Insert your LEDs. Use super glue to secure them if they're a bit loose.
Take note of the leads (anode and cathode). The anode (+) is longer than the cathode (-).

The Circuit
(Sorry, it's a messy work. I'm just excited to finish this project early.)
We will do the circuit in a parallel connection.
Solder a resistor to each LED's anode(+). Then run and solder the hook-up wire to all resistors so that all of these ends are connected.
Run and solder another hook-up wire to all the cathode (-) ends of the LEDs the same way as the anode.
You may refer to the diagram below (2nd pic).
For a more detailed approach, see the original instructable from Artificial Intelligence (https://www.instructables.com/id/The-USB-powered-LED-CD-lamp/?ALLSTEPS).
Chip off a small opening so that the two ends of the hook up wire (+ and -) can go outside (see comment 3rd pic).
After finishing the circuit, close the CD case (3rd pic). Check if the whole circuit fits well while the CD case is closed. If all is good, open the CD case again and peel off the remaining side of the mounting tape (inside) and close the CD case again. This will securely protect your circuit.

Testing
Test the circuit if it works (refer to the diagram/1st pic)...
1. strip off the end of your USB cable.
2. cut off the green and white wire and save the black (-)and red(+) wire.
3. from the circuit, temporarily connect the red (+) wire to the line where the LED's anode runs (the line where the resistor runs).
4. temporarily connect the black (-) wire where the cathode runs.
5. power on your computer.
6. plug in the USB and see of the circuit works (2nd and 3rd pic). if not, check your connections.
Installing the circuit to the candy jar (sorry, no pics)...
1. disconnect the USB cable from your circuit.
2. peel off the remaining side of the mounting tapes that are located from the outside of your CD case. stick it on the jar's cover.

Installing the Switch (optional)
(This is only optional, but looks good in mine.)
I've detatched the cover, drilled a hole and installed a toggle switch, then completed the ciruit permanently. You may refer to the diagram below.
And also I've drilled some small air holes at the back of the lid, by the way.
The toggle switch has two terminals. Solder both ends of the positive wire onto these terminals. See the 3rd pic for your reference.

Final Test
1. Re-attach the lid/cover.
2. From a powered-on computer, plug in the USB cable. Test the switch if it works.

Add Fish and Enjoy!
Do as you prefer. I used 3 Rose barb (tetras) and 1 albino Cory as test fishes. I'll have my Betta soon when I return to the Philippines.
I've placed some crushed corals and fake plants. You may use live plants too, but I'm not that sure if it will thrive on these LEDs. Added aged water, then the fishes.
