I am musing about a new timer based on the one I have already built (which is based on work done by hippy). as a prototype it work as well as anticipated.
The new timer will actually be 2 timers, each can be use as single input or 2 input, or inputs linked. Now the original project allows for each input to be inverted, which then runs through and SR latch, then through an Xor gate, clock signal added and finally that need to be inverted too.
As you can imagine that takes a fair amount of 2 input NAND gates, 12 for each timer, 24 total.
I can't seem to find packages containing more than 4 2 input NAND gates. Do they exist or am either better off (due to cost or some other reason) just using 3 quad NAND date packages. I know its not strictly PICAXE but the final project will be using at least 2 20X2. And this will be used for testing another PICAXE idea I have for updating some of my home made camera equipment
Thanks for any ideas.
