Today I received a small batch of PCBs - THT for hand soldering - and halfway building I had to troubleshoot a short on the input Vcc line.
I had a suspect: the 78L05. Well, not "him", but how I soldered it. While I had plenty of space on the board, I used the TO-92L footprint where pins are very close to each other. If you add a bit of rush, sub-optimal lighting and worsening eyesight (with age), a bridge is almost granted.

Next time I will use a wider footprint, nevermind if I have to bend pins. No wonder KiCad has TO-92L_Inline_Wide!
