205 junctions soldered so far, out of an estimated 800. Initially I was going component-by-component: install all the diodes, install all the 510Ω resistors, etc. However, I have to periodically reposition components that have already been installed, which can weaken or even break the solder. I changed my strategy to doing all the wiring for each column. That should minimize the number of times I have to re-bend a soldered lead. It’s slower to do it this way, but it’ll probably save time in the long run.
