DIY INSTRUCTIONS
This document gives detailed instructions that assume you have purchased a
complete Turing Machine kit from
assumes no previous knowledge of electronics.
To learn to solder try
the Adafruit guide to excellent soldering –
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 -

- Page 4 TURING MACHINE Mk ii Eurorack DIY Kit Version 1.01 (APRIL 2016 ONWARDS) Instructions Solder the single 47K resistor into position R6 as shown Solder the single 100K resistor into position R4 as shown Solder the two 1N4001 diodes into the positions as shown.
- Page 5 TURING MACHINE Mk ii Eurorack DIY Kit Version 1.01 (APRIL 2016 ONWARDS) Instructions Solder the two Ferrite Beads into place as shown. 3 x 14 pin 4 x 16 pin Next solder the eight IC sockets into place. Make sure the notches in the sockets match the notches on the silkscreen.
- Page 6 TURING MACHINE Mk ii Eurorack DIY Kit Version 1.01 (APRIL 2016 ONWARDS) Instructions Break off four of the 1n caps and save two for later. Solder those four 1n caps into positions C1, C2, C3 & C4. Next identify the twelve 100n capacitors (they are on a card strip, orange and labeled ‘104’).
- Page 7 TURING MACHINE Mk ii Eurorack DIY Kit Version 1.01 (APRIL 2016 ONWARDS) Instructions Next identify the two 78L09 voltage regulators. Make sure you check the codes correctly! Do not mistake them for the single TL431 or single 2N3904 included which look very similar.
