"Little" etching victory

[karbomusic]

It's flexible PCB for a digital circuit I'm building (it's a 25x30mm self-contained motion detector with WiFi) but I had already etched before I realized these were 6mil traces. Seems to have worked, not complaining.



Not audio related at all unfortunately but thought I'd share with my DIY pals here.

Congratulations!

So they are... but why?

Not much going on, no crowding.

Being a crude dude, I wudda drew them with a blunt Sharpie or 1/8" tape.

^I had been playing with auto route for fun and changed DRU rules etc. thinking they were 12mil. That also shrunk my pads to an nearly non-solderable size (hence the lack of crowding) but I was able to make it work.

I actually ran into a problem. Sensor wants 5V, WifI wants 3.3. I thought I had successfully massaged the sensor into working at 3.3 but apparently not the case, it fires all the time due to the incorrect operating voltage. Voltage divider appears to limit the current too much to run the WiFi so I was just cramming a LM317 in there so any space I did have is mostly gone.
