Another SMD prototype

Behold the wart zapper from Thomas Scarborough. Built it and ran it against 3 ugly warts that I have been trying to rid myself of for 3 or 4 years.

I won't post any photos of said warts

Ok, now on to a relay control for the Wolfgang spindle.

I need a relay control for my WG spindle to. What motor are you using with your spindle?
Glad to hear you zapped your unwanted growths

The one wolfgang supplies. Just a simple AC line voltage motor. Fixxit (another member) told me he located a source for these but he couldn't remember where he saw them. If this one goes, I'll be looking at a BL motor for RC cars w/ BL controller. To me all the noise comes from the AC motor (the brushes maybe).

Yeah I'm glad to be rid of these things. Fingers look like hell right now as I went medieval on them but I can see/feel them shrinking day by day.

here is a link to the motor he uses.

Maybe we should start a new thread with Wolfgang in the topic so it will be better searchable.

I decided to see what my results would be with a drewtronics 45 degree bit. The photos are from my new USB microscope

The first photo is with the 60-degree, set to .003" tool width, .003" DOC, and .003" step over

The second I changed it to .0015" step over.

Well after the vitreous paint experiment failed I went looking for other possibilities.

Here are some results. Apologies for lousy camera work.

[Jay C]

hey Zig, that looks really good. Have you shared the tool bit(s) you use to get such
nice traces?

[Drools]

I'm looking at switching from a through-hole design to a SMD design and I'm a little lost. I hope I can get results near what you have produced.
My main hurdle is in Eagle and designing the PCB to fit the FREE version restrictions? Are there and do's & Don'ts for designing SMD circuits in Eagle?

Thanks

Have you seen the Sparkfun tutorals on Eagle?
