[sdiy] [OT] LM13700 spotted in commercial product of big Manufacturer

[Roman Sowa]

Did you know that there used to be European Soldering Championship 
taking place during Productronica trade show?
Not sure if it's still organized though. Because of Covid last 2 
editions of national championship were canceled and that was an entry to 
go to European finals.
