Make a wooden digital clock. via instructables
How to build a wooden digital clock powered by an atmega168 (arduino) with a built-in alarm and games.
I first thought about making this when I saw an LED clock covered by a wood veneer . I liked it when I saw it, until I saw the price. This is when I decided to build my own, I wanted it to build it for much less, from solid wood and play games!
Step 1: What You Need
– 4, 18″ x 4″ x 1″ wood planks (I went with Maple)
– 85 Red LEDs
– 85 Green LEDs (Optional)
– 1 4 to 16 pin Demiltiplexer
– 15 NPN transistors (such a 2N3904)
– 1 ATMEGA168 Microcontroller (or Arduino)
– 1 20 MHz Crystal
– 1 5 Volt Regulator
– 2 220uF Capacitors (for power spike leveling)
– 1 Old Pocket Radio
– 2 1/8″ Audio Jacks
– 1 5-9V DC wall adapter
– 1 (or more) Old Game Controller(s)
– 4 3-1/2″ Wood Screws
– Solid Core Wire (easier to work with)
– Hot Glue Sticks
– White Glue
– Sand paper
For the game controller I use an Atari 2600 joystick (or even paddle if you re-program), but it is also compatible with with a Sega Master System Controllers, Atari 7800 joysticks (theoretically) or even Sega Genesis Controllers.
– Drill press
– Flat End Hobby Tool Bit
– Soldering Iron
– Hot Glue Gun
– Miter Saw
