Step 6: Possibilities
CONTROL OTHER DEVICES
The touch switch is used here to turn on a few LEDs. If you replace the LEDs with a 5 volt relay it could be used to turn on any device that the relay could handle. You could turn on AC or DC devices.
PORTABLE TOUCH SWITCH
While this LED lamp is USB powered, it could also be made more portable by using three aa batteries as the power supply.
CONDUCTIVE FABRIC TOUCH SWITCH
This touch switch circuit is ideal for use in conductive fabric switches where the touch switch plate is a hidden grid of conductive fabric or thread and you only have to touch near or on an area of fabric to turn on a wearable circuit.
LIGHT WEIGHT STRUCTURES
pic12 shows a back lit curved circuit board that has been etched with the same pattern on both sides. Because the circuit board fiberglass is so thin, LEDS can be mounted behind the board and will glow trough. This curved circuit material is ideal for wall lamps or other hanging circuits.
HEAVIER DUTY STRUCTURES
You can make the structures stronger by laminating two bent forms together or gluing a layer of fiberglass on the back with epoxy. Copper wire or other circuit board material can also be soldered to the main structure to make it sturdier.
