Introduction: Magnetic Companion Cube and Button Lamp V.2 (more Details)

This is a remake of my old one (https://www.instructables.com/id/Companion-cube-and-button-lamp/), now I made a more details instructable. If you like this idea, please vote for me for papercraft contest in the old one and other project if possible. I will be very appreciate if you vote for me (I want the cricut explore so badly!)

P.S: Sorry if my english is bad.

Step 1: What You Need

Material:
- 2mm and 1mm thick card board
- Companion cube template (http://tiffchow.typepad.com/voxblog/2007/10/weightedcompanioncubepapercraft.html)
- White LEDs (I use recycled ones)
- Glue
- Black and white paint
- Magnets (I use black magnet)
- Metal sheet
- Wire
- A small LED light (you can replace with a circuit to power the LED if you can)
- Sand paper (to prepair the surface for painting)
- Thin red and pink paper
Tools:
- Scissors
- Razor knife
- Paint brush
- Solder iron

Step 2: The Circuit

The circuit is easy. The hardest thing is making the switch. I use black magnet because it doesn't conduct electricity, so I use metal sheets as a contact point and the magnet just act as a...holder. The magnet need to place such way that can't be mixed up between the two leads
The power source is a LED light circuit. Mine conect to a series of 4 LEDs so I use the cricuit above.

Step 3: Making the Cube

Making the cube is hard and extremely hard to understand. Basically, you add an edge to connect the cube and still make it square. Because this is 2mm thick card board so we put 2mm edges to make the cube (like the picture). The bottom piece needed two hole so that the magnet can be fitted in place
After you cut out the squares, cut out the heart and cover with pink paper and cover it with a piece of 1mm card board like in the picture.

Step 4: Edges and Corners

Trace the template you cut out in the last step and add edges for gluing
The edge is put on a 1mm thick cardboard so add edges like in the picture (2mm for the cube's edge and 1mm for the piece thickness)
The corner is made out of 2mm thick card broad. the small 2mmx2mm block is needed or else there is a hole (in the picture). Also add the magnet to the bottom corner

Step 5: Finish the Cube

Add the electronic like the circuit, glue down the LED and close the cube.
Prepair the cube to paint by soak the cube in glue, let it dry and sand it smooth.

Step 6: The Button

Draw the template like in my picture. It should be big enough to look like the finished product. You should make it out of 2mm thick cardboard. then cover it with red paper and glue on a white ring.
After that, cut a cardboard box like the previous step. It should be a square box but I cut a rectangle instead.
Finish it by put in the electronic and close it up (I use the LED set in the lamp). The LED strip should be glued in the bottom of the box

Step 7: Finished

After that, just plug in the electricity an admire your work.
Additionally, you can add a switch, or even an sound effect if you can.

use an isolated psu!!! its dangerous!!!

I tried to design a isolated power supply but I'm not good enough so if you can, please share. Also it is only 12VDC so it doesn't shock so much.

Use a cellphone charger (5v), and 1 resistor per led, leds in paralell :)

Your psu is REALLY dangerous because the + or the - is directly connected to 220V.

Sorry for my bad english!

I'm sorry, but you didn't under stand. The lamp's circuit's job is to turn 220VAC to 12VDC, it doesn't directly connect to 220V, if it was, the LED would be broken.

This is the problem with ALL transformerless power supply... direct 220v trough your... body, finger... or something...

I see, you are right.
