if someone needs a 24 shotclock using TTL's try this  the clock source is derived from the power supply itself  proteus simulation http://rapidshare.com/files/358121741/24secshotclock.rari have not tested the design on a breadboard yet

di ko rin maopen.. baka sa compatibility ng proteus.. 7.2 gamit ko eh.. ------------------------------ anong chip ung ginamit? 74192 ba? malabo ung image eh.. hehe.. tnx redskin for sharing  ------------------------------ ayan yhandz, nanjan na ung circuit mismo..

@redskin pano ba mag set ng "number 24"? pwede kaya yan other digit aside from 24? EDIT: meron pala.. hehe nasa 4 bit input nya ang pag set... matingnan ng ang datasheet.. thanks  +1 sis

puede. set mo ang gusto mong number sa parallel input ng 74192

@redskin diba dapat sa VCC naka tie yung UP(pin5) ng 74192 yun sabi sa datasheet na try ko na ito sa breadboard sa 60 seconds

@redskin diba dapat sa VCC naka tie yung UP(pin5) ng 74192 yun sabi sa datasheet na try ko na ito sa breadboard sa 60 seconds  tama basa ko sa datasheet dapat sa positive ng supply rail ang up or dn input pero sa simulation takbo parin naman as intended kaya like sa sinabi ko sa hindi ko nasubukan ebreadboard ang circuit kayo na bahala gawa ng changes kung kailangan nyo gawin ang circuit and lets discuss kung ano ang mga problema

 yung circuit above kelangan laging sabay yung clear at load, sa revision ni tita redskin hindi na ganun at pede ring mag pause

sorri to dissapoint u pero hindi ko kenopya from anywhere ang circuit other than nagkataon lang na meron na palang nag nakaisip nito tulad na rin sa pagapply ng mga patents sa invention kaya meron hindi ina-approbahan kung sakali man meron ng nauna sa iyong ina-akalang me bago ka idea,,,

yup i agree, nde naman komot hawig at may iniba lang ng konti or (unting binago) ay kinopya na. all circuits are almost same lang, specially kung same parts din gagamitin, it will look like somebody else work. some designs are evolution lang of the previous one. its just like sa mga amps, same design topology so it really looks like kinopya lang because they look same. but sa biasing naman nag kakaiba, which is nde naman kalakihan din ang difference.

Matanong ko lang bakit naka default siya sa 24 seconds? shot-clock po ba sa basketball ito?
Pwede rin kasi lagyan ng DIP switch yong D0-D7 para programmable yong default shot-clock niya para sa ibang games.
