Hi all,
It can happen to anyone, building your Lectron circuit, connecting the battery and finding out that there’s a short circuit somewhere !
Well, a technique I used to apply is to connect a light bulb in series with the power supply.
This way, our transistors, diodes etc. are protected against excessive current.
The 9V battery will also be happy and will last longer this way.
Later on, I will propose an automatic fuse.
Many greetings,
Frank
