Binary Clock

[geneanthonytarca]

i want to know kung may nakagawa na nito dito?

siguro sa MCU meron na, but this one uses logic gates etc.


Schematic Here:
http://www.instructables.com/files/deriv/FZQ/ILLU/FIM95W1L/FZQILLUFIM95W1L.LARGE.jpg


1x 32.768 KHz Crystal Osc.
1x 560pF
1x 22pF
1x 4060 14bit ripple cnt.
3x 4028 7bit ripple
2x 4082 Dual 4 input AND Gate
17x 470 ohm Resistor
3x  14.7k ohm Resistor
3x N.O Switch
1x N.C Switch
17x LEDs

mas ok ba kung gawin 555 IC yung crystal at 14 bit counter?

EPIC FAIL.
subukan mo lang to see the difference.
malas mo pa kung wala kang precise na frequency counter.
at kahit may frequency counter ka, temperature changes lang skewed na yung timing...

maghanap ka nang wall clock, alarm clock, wrist watch na may "quartz" may 32.768 khz crystal yun.
mag review kna nang binary to decimal mo ngayon pa lang. pero nice project. do it in logic gates. boring kapag mcu.

i see..

may gusto lang akong itanong about dun sa diagram.

yung sa Part ng J1 di ko maintindihan kung anong component yun.

J1 malamang Jumper yan

[geneanthonytarca]

jumper papunta saan? may 1 , 2 at 3 pa kasi.

papuntang supply..

------------------

anong klaseng binary clock to? hehe.. clock na binary ang output?

[geneanthonytarca]

Yep binary ang output niya represented by LEDs which corresponds to a certain binary value to tell time.

1 2 4 8 16 etc.

its a DC Jack Connector.. two pins were tied together in GND and the other one is for VCC

planning to make this project ngayon linggo. okay din ba kumuha ng clock pulse through 60 hz ng ac line to get 1 hz pulses?
