How to make Double Sided PCBs in the home electronics lab.

The ICL7106 chip is a multi-segment LED display driver with some ADC stuff too. It looks like you just have to add a few passives in to turn it into a DMM. Probably not the most accurate thing in the world, but useful for basic projects.

Some of the PCBs (printed circuit boards) from the "Woking1" box. I think the larger one was once a fax machine.

The eerie glow of an ultraviolet exposure bulb.

 

The same light fixture set-up is used for both single and Double Sided PCBs.

Etched board with some of the ink removed with acetone.

Here's the PCB clamped and ready for the mini-mill to cut it to a precise size.

Another favorite! The light on 390 an laser etch pitting are dope.

PCB detail. Plate Through Hole (PTH) vias.

Gerber files for board

There are layout changes too, to accommodate the shape of the radio cavity. And it's a good job the next rev is underway because the first PCB got burned out last night.

just to the left centre, is the footprint of an atmega169 - 60 pin chip the same size as one used in the makerbot boards

I've set up to cut the PCB to approximately the right size using a hacksaw.
