Hankin Pinball A3 SOUND board getting close to finished.

Just need to add the component values and have a bit of a tidy up and it should be right to go. I will ask the board house to add the Hankin logo in the correct font as they did with the MPU.

Thanks, I just noticed (looking at the pics I posted) that we forgot to add a small cap to the input and output of the regulator. Hankin didn't have it BUT (as you would know) it is good practice to prevent supersonic oscillation of the 5V regulator IC.

I'll go and do that now before I forget......

There you go - that's better.....another reason it pays not to be TOO quick to send the files off and have boards made 

[Homepin]

I didn't like that - try again...................the caps should be 'as close as practicable to the input and output legs of the device' - according to the spec sheet.

Na, no need for those, we want intermittent hum and weird stuff going on  , Oh sorry, wrong brand. what a "dog" that would have been, it would be just a "rotten" job  if you left those out

Blank PCBs arrived today. All parts are already in stock for a short run of 20 boards. Once we have a sample batch of these assembled up we will try and get a full set of boards together.

Love your work Mike. Just wish i had a Hankin to work on - Almost snared a "Shark" recently - but it was fully working !

Looking forward to the full set of boards being available.
Boards to get a friend's Howzat working as good as it looks.
