Fountain pen highlighter build

Highlighter Fountain Pen!

I combined a moonman V2 with a 6mm pilot lettering pen to make a right dapper highlighter

One of my basic electronics students gave me a fountain pen and sent me on an inky path. I wanted a highlighter and saw a build on reddit

It’s still a bit wet so the flow isn’t quite right but

it works!

Edit- I finished a true hacker mod and it went very well!

Moonman highlighter conversion


This is neat. Would probably look nice with some LEDs to light it up…

Thanks! It’s super wet. I wanted to try something but wanted to document it in case it never worked agian lol!

Maybe some UV LEDs for the fluorescent ink?
