DIY INSTRUCTIONS
This document gives detailed instructions that assume you have purchased a
complete kit from www.thonk.co.uk. It also assumes no previous knowledge
of electronics. To learn to solder try
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 module otherwise.
TOOLS REQUIRED
Soldering iron, tweezers for SMD parts, 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 -

This isn’t about perfectionism, you are very likely to end up with a destroyed, damaged or defective unit if you’re not hitting that standard.

Good technique is important though. This video is a great introduction to the standard way of soldering SMT resistors and caps by hand: http://youtu.be/PU7wLcuqc-I September 8 2014 www.thonk.co.uk...
- Page 4 YouTube video linked on page 1 and the ‘good joints’ image on page 2. Next solder the single 330R resistor into place as shown. NOTE! Keep a couple of resistor legs spare as you will need one later! September 8 2014 www.thonk.co.uk...
- Page 5 Next solder the single 4.12K resistor into place as shown. Next solder the single 10K resistor into place as shown. Next solder the two 20K resistors into place as shown. Next solder the seven 100K resistors into place as shown. September 8 2014 www.thonk.co.uk...
- Page 6 SILVER RING BOXED END NOTE! Orientation is vital. The silver ring on the diode should match the boxed end on the silkscreen. NOTE! Diodes can be damaged with a long exposure to the heat of the iron. September 8 2014 www.thonk.co.uk...
- Page 7 Next solder the three 100n caps into place as shown. Next solder the 14 pin and 8 pin IC DIL sockets into place as shown. Make sure the notches in the sockets match the silkscreen, on this board they face each other. September 8 2014 www.thonk.co.uk...
- Page 8 Next solder your newly created 8 pin single line socket into place. The other half of the socket can be kept for future projects. Solder the single 1n5 capacitor into place as shown. Solder the two orange fuses into position as shown. September 8 2014 www.thonk.co.uk...
- Page 9 NOTE! DO NOT MISTAKENLY SOLDER ONE OF THE TWO 47uF NICHICON ELECTRO CAPS HERE! NOTE! Orientation is vital. The longer lead on the part should be positioned in the square pad marked with the plus/positive symbol. September 8 2014 www.thonk.co.uk...
- Page 10 NOTE! Orientation is vital. The longer lead on the part should be positioned in the square pad marked with the plus/positive symbol. Solder the ten pin Eurorack power header into position as shown. September 8 2014 www.thonk.co.uk...
- Page 11 78L05 into position. The rounded side of the component faces out towards the edge of the board. Remove the nut and washer from each pot and cut or break off the small anti- rotation lug on each one. September 8 2014 www.thonk.co.uk...
- Page 12 Solder into place as shown so there is one wire going into each of the 5 pads as shown. You can now split the wires apart. September 8 2014 www.thonk.co.uk...
- Page 13 Now solder the wire going from the ground pad on the PCB (my wire here is black yours may be a different colour!) to the centre of the jack lead. The Ground pad is the one closest to the power socket. September 8 2014 www.thonk.co.uk...
- Page 14 1cm further than the closet vertical pin on the CV1 jack. Check the panel legend for reference! Strip then solder the CV1 wire (red in my photo) to the nearest pin on the CV1 jack September 8 2014 www.thonk.co.uk...
- Page 15 In my photo this wire is yellow. Finally solder the wire from the IN pad on the PCB to the vertical pin furthest from the PCB on the IN jack. In my photo this wire is brown. September 8 2014 www.thonk.co.uk...
- Page 16 Finally connect the power cable as shown, so the red stripe is at the point on the board marked –V, closest to the frontpanel. Next we’ll connect the power, switch on and user a Multimeter to trim the module. September 8 2014 www.thonk.co.uk...
- Page 17 Alternative CV response is possible - you can set it up to accept 8V or 10V signals by changing the zener diode to an appropriate value and trimming as above. I did a few @ 8V as prototypes when I ran out of 5.1V zeners. September 8 2014 www.thonk.co.uk...
