I am looking for a schematic to build a prototype circuit. The circuit is a twelve channel sequential pulse counter. Each channel should have:
A. Positive and Negative screw output connector
B. Variable output (Miliwatts) between 1mw and as high as possible.
C. LED to show what channel is active
D. On and off switch to disable that step if required (Not essential, but handy)
The counter works in a similar way to the scanning lights on KITT (Knight Rider Car), except that they do not reverse direction. (In a perfect world, all 12 steps could be counted as fast as 40 million times a second. I’ll be happy with as fast as possible)
100000000000 (Step 1)
010000000000 (Step 2)
001000000000 (Step 3)
000100000000 (Step 4)
000010000000 (Step 5)
000001000000 (Step 6)
000000100000 (Step 7)
000000010000 (Step 8)
000000001000 (Step 9)
000000000100 (Step 10)
000000000010 (Step 11)
000000000001 (Step 12)
100000000000 (Sequence Starts again)
Main circuit design should incorporate the following
A. 12V input
B. Main on off switch
C. Switched auxiliary 12V +/- output screw connector
D. Expansion bus with:
Switched 12V +/-
12 pins, each connected to the positive LED (For external counter)
Common ground for LED
Ideally this circuit should allow the LED's to be displayed in variable frequencies from KHz to MHz. Also, I would like the frequency between steps to be changeable. Ideally this circuit will have the highest output in Milliwatts, and the fastest refresh off to on in sequence through steps one to 12, and back to step one. However as it is for a prototype, and is test equipment, some flexibility would be good.
Anyone who can help design this circuit will be credited for the help. If you have any questions, please ask.
Thanks.
