Vaus Arkanoid Paddle Clone

The top cover required some Dremel job to accomodate to eliminate an interference with the recessed base of the pushbutton cap.

But then if fitted very well.

The height of the shaft above the top cover is about 10mm, just enough to tighten the screw of the knob I am using.

And that's it!! Another completed project!

PCB mounted on the case. Unused wires have been isolated using shrink tube.

Here are some pictures of the board after assembly of the components.

The potentiometer leads were too short to reach the board pads and required the use of some bare wire to extend them.

The potentiometer value used was 10k instead of 4K7, but the timing capacitor was reduced to 0,47uF to compensate.

Trimpot R7 is optional. Instead a 2k7 resistor was used for R1 and it provided a counting from 90 to 400 (approximately) which is right within the desired range.

Boards arrived from JLCPCB

And they fit perfectly on the CP-011 box

The paddle " character "  was a little glitchy while playing the game. The first guess was the wiring from the counter to the shift register but it  was OK.

Second guess was some glitches found in the capture by logig analyzer

A 100nf capacitor was placed from the output pin (pin 1 - UP ) to ground and the glitches disappeared from the capture and the behavior of the paddle character now is smooth as expected!

PCB and schematics were updated
