I got yer 9V version right here. "We don't need no steenking charge pumps."

What is the benefit/reason to use 18v over 9v?

 

[Chuck D. Bones]

None, really, which is why we changed to using 9V power.

Got mine wrapped up a couple days ago, it came in handy with another project! Thank you for sharing this with us @Chuck D. Bones, and thank you for the threshold modification suggestions, @cooder!

I'll stick a knob on the rotary switch at some point, but for now, it's a great tool!
