Hello mikrosoft,
Wow home made custom pens. This sounds very nice in itself. And the drip tips should be a great seller for him perhaps. You could probably get what 4 or 5 from the material it would have cost to make a pen.
Tell your Dad good job for me
I`m actually going to be getting my first drip tip soon.
Now I like that tube you have the RCA jack in there. A Blue one very nice and all I have seen was this silver kind. I have a question on that if you don`t mind?
Do you have a switch on it?
Here is mine I posted a while back. It has a LED in the cap with a momentary switch that will more then likely fail due to no mosfet but I don`t think I can jam any thing else in the cap. It will be easy to change the switch out though when it does fail.

Again nice job on that Drip tip would love to see some of the other colors you and him come out with.
