+# 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
+
+> 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:
+
+![](left-hand-pcb-pyralux.png)
+
+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:

+
+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:
+
+![](right-hand-pcb-with-teensy.jpg)
+
+
+Here the left hand:
+
+![](hotglue-left-hand.jpg)
+
+That's all for now, this guide will improve over time! (TODO!)
