Hi everybody,
Today I'm posting my newest creation: The EGG-CLOCK!!!!
This little clock was made all by myself (lot of hard work :D), and the first thing you may notice is that it´s not too small, so i just
want to say that's the smallest thing I could create, if you still think its cool, you like it or you just don't dislike it THANK YOU A
LOT for you support!!!
Now, let's continue with the things you want to read: how it was made.
When I imagined it it looked really simple (the circuit itself is easy to do), but when I tried to put all that inside an egg, I faced some
problems so it ended being a 2-egg clock :|
Construction begins in step 1...

Stp1:
The first step as you have read was designing, I took a whole day to do it, to make it fully functional. This step doesn't really have
too many things to explain, I used PCB wizard to make the design (pretty simple), I just place the components and draw ALL the tracks.
After some time I produced the complete design that consisted in:
1.- Seven segment display driver
|x1 Picaxe 18M2
|x1 7 segment display
|x1 Board
|x1 Potentiometer (Brightness controller)
2.- The Clock Driver ("Egg Driver" as seen on the photos)
|x1 Picaxe 20X2
|x1 DS1307 and it's resonator (Real time clock)
|x1 LED
|Many resistors
|x1 Board (it was difficult to make it like a circle)
3.- Power Supply & Programmer input
|x1 Board
|x2 3v Batteries
|x1 5v voltage regulator
|x1 Switch (to connect the MCUs to the programmer input)
|x1 3-pin female header (programming input)
So this was the first step...
Note: As you may have noticed in the photos (and in the materials), there's only 1 7-seg display. That is because it's designed to show a scroll* not a constant display.(*explained later)

WILL YOU POST THE SQUEMATIC PLEASE.
IS WONDERFUL ! GOOD JOB
And sorry for not explaining myself correctly, If you want the schematic I will post it by Monday if it is okay.

Source code? Could I upload that through a mac or pc only?
Cheers
(You may also program them using Yenka http://www.yenka.com its free for home users)
About PICAXE: they are basically PICs (Microchip), the difference is that they are pre-programmed with a bootstrap code, and that they are programmed in BASIC language; the reason I love these chips is that they only use 2 resistors as programmer so that made them perfect for this project. (If you noticed it, there are actually 2 programmers includes in the egg-driver)
And the other thing that you will need: a serial RS232 port OR a USB to serial converter ( there is one made by rev-ed AXE-27 and other ones based on the FT232).
If you need any more help or have ANY question about the egg-clock, please tell me so I can answer back as soon as see your comment. Thank you.
