I needed a birthday gift for my friend's daughter and i didn't want to just buy her any thing instead i decided to DIY this gift so this instructable shows the process of its made.
Step 1: What We Will Make
basically this box lights a color for each combination of the switches as follows:
- Red + Green = Yellow.
- Red + Blue = Violet.
- Blue + Green = Turquoise.
- Red + Green + blue = White
Step 2: What You Need
3x Push button switches
1x RGB LED 5mm
1x USB Connector "A" Type Male
1x DC Power 2.1mm Connector on PCB
1x DC Power 2.1mm Barrel Plug
1x 1K Ohm 1/4-Watt Resistor
1x 220 Ohm 1/4-Watt Resistor
2x 100 Ohm 1/4-Watt Resistor
1x LED 3mm
1x 1N4001 Diode
1x 3.7v Battery
Step 3: The Board
With the attached eagle files you can either make it in home using the Toner Transfer Method or you just manufacture board.
Here i used Toner Transfer Method You can find many tutorials for this method if you're not familiar with it like this one as a start https://www.instructables.com/id/PCB-Making-My-Method/
Step 4: The Box
we will need an enclosure for our board here i made it out of wood but any plastic box will do.
next we need to drill holes for mounting the switches 2 for each and one 10 mm hole for the LED.
to give the box a nice finish i covered it with white sticker paper.
Step 5: Soldering
we will start with the switches and solder 2 pieces of wire to each one after securing it to the box with glue.
then the rest of the components will be soldered according to the schematic.
the battery used here is an old phone battery (800 mah) but any 3.7v lipo battery can be used.
then soldering the other end of the switches wires to the board and placing the board in the box before closing it.
Step 6: The Cable
in this step we will make the charging cable we only need to solder 2 wires:
- the positive of the barrel plug with the positive of the usb connector (the first pin from the right)
- the negative of the barrel plug with the negative of the usb connector (the first pin from the left)
Step 7: Play
after closing the box try pushing each switch and watch the colors changes.
that's it you made it.
