How To Take Care Of Poodle Shitsu Mixed Dogs

matrix of 100 Led By-Pass Ethernet

This circuit is an oscilloscope to LEDs, but is far from being a tool for laboratory use is didactic and the learner's.
It employs an array of LEDs 10 x 10, a Johnson counter
in this case the CD4017 that has 10 outputs, which we use to generate the horizontal sweep. And the vertical sweep is developed according to a VU meter LM3915 is 10 levels.

Both the input gain and horizontal sweep speed is set using two potentiometers, the input level is varied at the entrance of LM3195 and base horizontal sweep time is varied by potentiometer commands the LM555 timer the CD4017 clock.

The following diagram show the address and PCB. This

link is the PCB in pdf format ready to print on transfer paper.

upgrade the circuit here some photos taken this day as the arm recently to test it, there is also a video.
