idk it just seemed so simple there was no need to even make a pcb for it. just bend one pin as a contact for one side of the smd chips then use the wire for the other side.
And the resistor fits in perfectly, but i can see the fact that a pcb will look a ton better.
So this means removing the 100Ω VR doesnot affect anything , and the total current output still depends on how well we choose the other resistance?
For instance a 4Ω Resistance would give just about 310mA while remaining circuit remains the same and the VR also eliminated..
