DIY INSTRUCTIONS
This document gives detailed instructions that assume you have purchased a
complete Turing Machine kit from www.thonk.co.uk after April 2016, it also
assumes no previous knowledge of electronics.
To learn to solder try https://www.youtube.com/watch?v=IpkkfK937mU and
the Adafruit guide to excellent soldering – http://bit.ly/1l77tF4
Watch and understand that whole YouTube video! If you’re not achieving the
results shown in the video then you need to buy new tools or seek advice.
You will not end up with a working unit otherwise.
TOOLS REQUIRED
Soldering iron, snipe nose pliers, wire strippers, small flat head screwdriver
and diagonal cutters AKA snips AKA side-cutters. A Digital Multimeter is
always helpful for checking for bad solder joints and continuity. Thonk sell a
range of inexpensive tools here - http://bit.ly/1jxqF3n
