Picture of ALL-IN-ONE CLOCK

For this proyect I used Picaxe microcontrollers.
This clock involves all the types of comunication between MCUs i know to use.
It includes: i2c, infrared, paralel, 1 wire serial, and 2 wire serial (data bit-clock).

Step 1: Where does the hour come from???

To begin I used the DS1307 RTC to provide the hour to all the other MCUs. It is pretty esy to use it if you know how to usw i2c communications.

EDIT: I've added an schematic of the circuit, notice that is a little bit different from the original circuit because it is a little bit better and less expensive. The main difference is the removal of a Picaxe 08m that was working as the MAX7219 driver, however it is possible to link the 20x2 that receives the IR signal to the MAX7219. Other changes include the 40x1 in the original circuit, I replaced it with a 20x2 and the 18m2 that receives the IR signal was replaced by another 20x2.

Thanks a lot... This project will really help me because most of the clock projects are from arduino which is rare in our country.

Please sir.....i really need the schematic diagram of this clock for a school projects, please i have tried to download the schematic but can't go well with it.
please i am begging you for the diagram, my email address is (dnkwenti@gmail.com)
thanks and i will be waiting to read from you again.

Thank you, I don't know the exact cost, because I used many spare parts I had in my component box, but I can give you an aprox. $70-$60 USD I used sparkfun prices to calculate it, it was more expensive for me because I use the mexican currency (pesos) (1 dollar= 12.5 pesos), so I think it will be cheaper for you.

This number varies because I'm not sure of the price of the acrilic bar (I think it's very cheap), wires and boards ( if you add the 3 boards price it may reach $80)

Add 3-4 days of work, (the led display assembly takes a lot of time) and you will have your own all-in-one clock!

Your English is very, very good. Do not worry about it. Your English is better than that of people whose English has been corrupted by a lot of texting on their cell phones.

This is a nice project. Do you plan to build a case for it? What would you say the approximate cost is to build it?

Thank you for a nice Instructable.
