The aim of this project is to make high grade all diy AFM.

Got the components but it turns out that they too small to work with. My CNC machine cannot go beyond 1mm resolution. 

So now waiting for converter from 0.5mm to DIP-16, from Poland.

My first try to solder this tiny components ended up by soldering all together 😕 but second was more successful.

TADA 🎉 !!!

Now I can proceed to building the power supply for this project. 

Not so fast... 

I was trying to connect this IC to the 5v and I couldn't find GND terminal. What?! 

It turns out that GND is underneath the chip. I could resolder it but the connector doesn't have GND pad. I guess I should make a hole in the connector PCB and connect. This is another setback.

I guess I should find the components by myself but this reference got lots of good ideas. I guess it worth the pain.

Luckily I have CNC machine, after gently curving through PCB I got this

The GND terminal is exposed! Hopefully I didn't break anything in the process.
