It fooled me.
But then again... I have a vision problem. A really bad vision
problem.
So I examine everything with 7 diopter glasses.
I looked at the CHOC board and saw GREEN in between SILVER?
squares.
Never for a moment considering that rows of silver were shorted
together.
so
I ask the question WHY?
Why not have ALL those pads be visibly connected like in this image
I edited to show it:
I definitely agree that is a good design to have the multiple rows
of perimeter
and the internal groupings.
I have done almost the same exact thing with my proto PCB I kitchen
etched.
?
I often have extra proto pads I add to PCBs in? groups of three.
Looks like an alien army.

Rob,
I don’t get it. It is not hidden layer. It is just covered by
solder mask. The interconnection is shown on the silkscreen
printing on the top over layer.
Welllllll? ....yes... its official.... I
am not qualified to operate this appliance.
I had some Choc Perf Board here that I thought would be
good for experimenting with
rotary encoders.
Seemed simple enough.
I had snapped them apart and was playing with just one?
of them
and I saw what looked to me like 8 completely isolated
pads ....what you see here in the GREEN circle.
Boy was I wrong.
I had soldered a 3 lead rotary encoder into the purple
marked pads and added 3 yellow wires to play with GROUND
and A and B in the
rotary encoder example sketches.
This failed to get the desired results and kicked this
for 2 weeks.... using various encoders......
and then yesterday I used an ohmmeter to figure where I
might be shorting out my soldering.
And then found there is a sandwiched layer where the RED
and BLUE are.
I don't get it.......
why the hidden layer?
Why not have the traces all connected on the solder side
of the board where you can see it?

I like perfboards but have never seen one like the one you
used to build your DSB FTB rig.
Any clue on how to find one like that?
