You know what I used to like were the electronic training kits that had the
leads attached to springs and you’d patch the kits with wires to form the
connections. Totally impractical for building anything permanent but was a
great way to learn electronics for a blind fellow like me anyway. Built radios
and oscillators etc by hand following the wire by numbers book.

Unfortunately, the spacing happens to be an industry standard to accommodate
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. :)
