This version was intended as a gift, so it's in a few contests like the Holiday Gifts challenge. Please, if you like it, feel free to comment, rate it (according to what you think it deserves) and please, please vote for me.
In that guide I stated that there would be a future version of the clock with some funcionality additions along with a much neater and cleaner design, well, this is it.
BTW, please like me on facebook.
UPDATE: Winner from mini contest ANNOUNCED! Congratulations to Goalie1, who won a 3 month pro membership simply for being my subscriber.
Don't worry if you didn't win this time, i'll be running many more contests like this periodically, some with even 1 Year Pro Memberships!, so stay tuned and always remember to check my new 'ibles.
Step 1: So, what will I need?
For the circuit you'll need;
- 13x LEDs, color of your choice.
- 13x Cheap LEDs, color doesn't matter, as these will be used only for testing.
- 13x matching resistors to apropiately drive your LEDs at 5 volts (you can calculate the value here).
- 1x Atmega328 with the Arduino Bootloader (you can use an atmega8 or 168 aswel)
- 1x 39x39 holes breadbord style PCB.
- 1x P-channel MOSFET
- 1x 16Mhz crystal+ caps (22pf)
- 1x LM7805
- 2x 100nf caps (104)
- 2x 220uf caps
- 1x Screw terminal
- 1x WallWart 7.5 to 12 volts out.
- 2 pieces of plywood of about 20x20 CM or about 8x8 inches.
- Wood glue. (any brand will do the job)
- linseed oil.
For the circuit;
- Soldering iron.
- solder sucker/solder whick
- (optional) helping hands
- Dremel (if your PCB is too big and you need to cut it to size)
- An Arduino or an FTDI breakout board to program the chip.
For the wooden body (if you're making it as mine);
- A Milling machine
- Some clamps
- Something heavy to keep both pieces of plywood together while the glue cures.
- Table saw/circular saw to cut the plywood to size.
- A caliper
- A pencil
