Has someone invented heat shrink tubing (or an equivalent) that you don't have to remember to put on before soldering your joints yet?
No I don't know how it would work, but two of three joints today were near misses and it seems like we should be able to come up with *something*.
@cincodenada McMaster sells some that has an adhesive strip to close it around the wire but I think it only comes in large diameters
@cincodenada I've only used it for plumbing hot fixes, but I imagine self-adhesive tape could work well? There's some sold specifically as electrical tape.
