Ok, confession time.
A while ago a TV crew came to my workplace, and wanted some shots of "people looking busy". They had an eye on this particular piece of electronics and wanted me to fiddle with it, so I took a screw driver to "adjust" the trimpot, but in hindsight, the shot was probably much to wide to catch the trimpot, so it probably just looks like I'm very concerned why a board doesn't work while I screw around it.
The segment aired on national TV.
