* Dactyl Flexible PCB Rough Guide
[[workbench.jpg]]
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
#+BEGIN_QUOTE
NOTE: If you only have an Inkjet make photocopies of the print out,
voilà Toner based copies!
#+END_QUOTE
[[http://www.instructables.com/id/Toner-transfer-no-soak-high-quality-double-sided/][Here'sa handy toner transfer guide ...]]
Print these PCB designs out...
Left hand:

Right hand:
[[right-hand-pcb-pyralux.png]]
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:
[[madness.jpg]]
Solder the MCP like so:
[[left-hand-mcp-1.jpg]]
[[left-hand-mcp-2.jpg]]
Solder the Teensy 2.0 like so:
[[teensy-1.jpg]]
Some interesting pull up 10k resistor business here... (TODO add a small
diagram and notes)
[[teensy-2-fuxor-reziztorrs.jpg]]
Each hand of the keyboard will wire up like so:
[[right-hand-pcb-1.jpg]]
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!)
