And so, nexus wants me to make him a counter before the month is up. Yep and its not easy to say no to him. OK, its easy but call me stupid but I can never resist a challenge. But in actual fact, in order to really satisfy the project, it needs a microprocessor. But since I do not have one ready nor know what code to use, I decided to use the Off-The-Shelf solution.
Oh, how wrong we were on this wretched path....
So, I called them up and asked, "Do you have a
3-digit down counter?". "Yes we do, fro Rm39.90"
was their answer. And so, in the end, I got them.
But to tell you the truth, there is a story to this.
they were technically right.
display costs extra, and so I had to get it
as well. But no, this is still not the end.
and immediately, I was very very angry. Just
like it said in the picture above, the clocking
circuit does not exist. You have to build them
yourself and using the above is not a good idea
since it is a manual clocking i.e., 'Push to count'
well, its just a frigging PCB with three 7-segment
LED displays. Yes, yes, its a rip-off. I can build the
circuit for these two projects easily. But the problem
is, I do not have the time nor the luxury to do so
nor make it more efficient.
resistors? There no holes in the PCB for these
resistors! What the .......!
would have to modify the wiring from the counter
module to the display module. And if i do not want
to, I would then have to modify the power supply
for the display and also the counter. Sheesh. What
a load of @#$%&!*@#!!
And here I am, thinking I could just solder them and it would work. But no, now I have to modify the power requirements, create a clocking circuit, etc. So now, I have to rush through the theory part before my next trip to Pasar Road this Saturday.
