How To: Fix-up Your Keyboard to Work in the Dark
| by Francis D'sa
Working, gaming or surfing the Internet can actually keep the rest of your family members awake through the night. Leaving the lights on would be sure to disturb everyone around. But if the lights are switched off, you can't see what you are typing, which is a strain on the eyes and frustrating. A small dim light can illuminate the keyboard while keeping the lights of the room switched off.
You would need an old keyboard, two bright white LEDs, some stiff wire, soldering iron and soldering wire.
Locate the Scroll Lock LED and remove it. Solder two pairs of the stiff wire to the terminals
Now pass each pair of wires through the two holes and neatly conceal the internal wires inside the keyboard. Solder the other ends of the wire to the LEDs. Check the positive and negative terminals and carefully solder the LEDs to the wires. Finally close the keyboard again.
Drill holes at the two extreme top ends of the keyboard and pass each pair of wire through them
Solder the LEDs to each pair. Use a housing eor heat shinkable shielding tubes over the LED if required
The workshop demonstrated here is very crude, and you can make it neater by using LED sockets and other materials to give it a more professional look.
