Mike,
Sadly perhaps Eric is correct. I've seen larger bread boards many years ago
with widely spaced holes meant for larger components but now-a-days 0.1 inch
pin spacing is all you get.
Unless you're talking surface mount parts then they get much closer indeed
and us bats are entirely out of the picture with surface mount.
I've used bread boards, and the setup from Canakit which my wife and I
discribed looks as feasible as most. You just have to use a stiff wire or a
stylus to count holes.
Personally I'd much rather use plain old vector board with 0.1 inch spaced
through holes and wire things up and solder. Most would disagree with me
on that particularly for experimenting.
As for color codes, a DMM with a capacitance range as most have is the only
practical way to identify part values so far.
The fact that you got your first project working, apparrently with no
sighted help? shows it's feasible. Frustrating yes, for sure but workable
in the long run.

Integrated chips and other precisely spaced components. I worked extensively
with these back in the 1980???s when in high school and later at DeVry
Institute of Technology. Believe me, even the sighted can have issues with
using these boards. I can tell you that using another type of board (for wire
wrapped circuits) can be a real nightmare for us blinks.
Btw, I have been having some thoughts to getting back into building my own
circuits. I still have a visual memory of how things can be placed and it???s
not all that hard to use a small set of needle nosed pliers to bend leads to
the right distance. And yes, with some short wire leads, you can put
together a surprisingly neat circuit that is even easy for a blind person to
follow.
Now, I just wonder if there is an app that will read the color codes on the
resistors as well as the values stamped on the capacitors.

Hey guys,
So I finally got a multimeter and broke the first visual barrier (reading
resistors) and five minutes later I've hit another: breadboards. They're
like an Excel spreadsheet for Ant-Man. If I could shrink to the size of an
ant, I might have a shot at putting everything in the right place, but so
far that's my best guess as to how to crack this one. The "cells" are
spaced way, way too close together, and when components have 3 or 4 wires
that need to be plugged in at exactly the right place, I just don't know if
I can do it. I got one of my projects working by sheer fluke, plugging
stuff around wherever I guessed the crappy diagram said, but I can tell
this probably isn't the right way to do things. :)
So is there such a thing as a breadboard with better spacing between
cells? Or maybe a way to link two wires without being required to use
one? I heard somewhere that "electrical tape" can tape them together and
they would still conduct electricity, but that sounds pretty far-fetched.
Either way, I'd be interested in any strategies you guys use to get by this
insanely way-too-visual obstacle. Thanks in advance. :)
