# Dactyl Flexible PCB Rough Guide
For now, take a look at the images and try to figure things out, I know that's not great (it's better than nothing!)
## Making the PCB
Get two sheets of 6in square Pyralux™. Use the Toner Transfer
method to etch the Pyralux sheets as you would a usual PCB
> NOTE: If you only have an Inkjet make photocopies of the print out, voilà Toner based copies!
[Here's a handy toner transfer guide ... ](http://www.instructables.com/id/Toner-transfer-no-soak-high-quality-double-sided/)
Print these PCB designs out...
Left hand:
Right hand:
When you're done etching, you'll need to carefully cut the pcb into
pieces... See the images below.
## This is Madness...
The thumb cluster pcb for the left hand:
Solder the MCP like so:
Solder the Teensy 2.0 like so:
Some interesting pull up 10k resistor business here... (TODO add a small diagram and notes)
Each hand of the keyboard will wire up like so:
Teensy goes here... note the rows soldered to the teensy via the Pyralux:
Here the left hand:
That's all for now, this guide will improve over time! (TODO!)
