hi

i want to make a T flip-flops with only discrete components no IC chips, i want to make something like this


http://www.facstaff.bucknell.edu/mastascu/elessonsHTML/Logic/Logic5.html

( the last one with 4 flip flops )


will that works if i use this bistable schematic?

i know it most be like 1 0 0 0, ( to start) but i dont understand how the "DELAY occurs" ?

i mean the first flip flop last 1 sec , the second flip flop last 2 sec, the thirt flip flop last 4 sec, and the fourth flip flop last 8 sec?
how it "delays" the time?


please help me! i like electronics and i want to learn more

 

The delay comes from the "clock". They toggle each time the clock pulse changes. What ever frequency your clock pulse is, that is the delay.

While learning how some thing works is good and needed it doesn't help much to actually do it. You wouldn't make your own resistors or capacitors to learn how they work would you? Just my opinion, from some one who is still learning.

 

I'm with shortbus. Build your counter first with IC flip-flops. Once you understand how that works, then you can build the flip-flops from discrete components if you are still inclined.
