Page 3: Introduction
INTRODUCTION Thank you for your interest in/purchase of the Mutant Hot Glue DIY project! It is my hope that you find this design a useful addition to your modular synthesizer. This assembly manual will show you how to build your Mutant Hot Glue module in the eurorack modular format. -

STEP_00: Resistors + Diodes 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 HEXINVERTER ÉLECTRONIQUE, 2015... - Page 5 Next, install the resistors. The resistor colour codes for 1% metal film (as supplied in the kits) are as follows… 470R 4k99 1k91 12k4 100k 57k6 169k 200k 383k 300k 576k 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 HEXINVERTER ÉLECTRONIQUE, 2015...

Page 6: Step_01: Ic Sockets
PCB and book over for soldering. This keeps the IC sockets nice and flat while you solder them in. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 7: Step_02: Power Header, Capacitors + Purple Led
The electrolytics can be installed now. The negative (-) strip on the capacitors must be aligned with the shaded (black) semicircle area on the PCB silkscreen. Just like the LED, the positive (+) leg is the longest. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 8: Step_03: Pin Headers
It might be a good idea to screw the PCBs together while you solder the pin headers, if you want to guarantee they are aligned well! MAIN PCB CONTROL PCB 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 9: Step_04: That2180, Test Points + Jumper
Solder in the 10k trim potentiometer for the SYMMETRY ADJUST calibration point • Finally, solder in the THAT2180 VCA chip. Be careful not to overheat it, and make sure the notch is aligned where indicated! NOTCH IS HERE 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 10: Step_05: Take A Break
Wear eye protection and try to prevent the clippings from flying all over, by cupping your hand over the cut as you make it! These little bits go flying off in all directions very fast when clipping. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG10 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 11: Step_07: Place The Parts
Place the 3.5mm jacks, potentiometers and ON-ON toggle switch into the CONTROL PCB but don’t solder them in yet! • We’ll do the panel LEDs and 10k trim pot later… Install one of the nuts onto the toggle switch for now 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG11 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 12: Step_08: Panel Fitment
PCB with your finger while you reheat the one leg you soldered. Leave out these jack nuts for this step. I shouldn’t have left these on (oops)! 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG12 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 13: Step_09: Jacks + Toggle Switch
Unscrew the nut for the toggle switch slightly, to raise it to the same height as the panel. • When you are happy with the fit, solder each jack and toggle switch, going back to check that they are nicely against the panel each time. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG13 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 14: Step_0A: Leds + Trim Pot
Loosely fit the purple and orange LEDs in their places, making sure to install the longer lead to the positive (+) indicator on the PCB • Fit the remaining 10k trim pot in its place on the CONTROL PCB (don’t solder it yet!) 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG14 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 15: Step_0B: Align + Solder
Once again, fit the panel to the CONTROL PCB using only a few nuts • Carefully align and solder the LEDs and trim pot so that they fit the panel properly 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG15 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 16: Step_0C: Install Ics
It’s time to install the ICs in their sockets! • Be careful to install them in their correct orientation. If they are reversed when you power on the module, the chips may be destroyed. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG16 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 17: Step_0D: Assemble The Pcb Sandwich
MAIN PCB on top of that and screw it in a little more gently. This will make it easier should you have to unscrew the MAIN PCB later – it should avoid accidentally loosening the CONTROL PCB’s screws from the standoffs at the same time as the MAIN PCB’s screws. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG17 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 18: Step_0E: Looking Good
Apply power to your module to make sure nothing gets hot or lights on fire. Does everything work okay? • If you don’t care about having a perfectly distortion-less compressor, go ahead and skip the next step: STEP_0F: Compressor Calibration. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG18 HEXINVERTER ÉLECTRONIQUE, 2015... -
Page 19: Step_0F: Compressor Calibration
STEP 1: If you are using an oscilloscope, clip your probe to the gnd and SYMMETRY TEST POINT clips on the back of the module which you installed earlier. If you are using an O’Tool, patch into the COMP output. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG19 HEXINVERTER ÉLECTRONIQUE, 2015... - Page 20 At first glance, this might seem okay – but pay close attention! – the output waveform (blue) is above and below the input waveform! This is not correct, as we will see in the following correct example. 04.24.2015 Mutant Hot Glue DIY assembly manual v1.05 PG20 HEXINVERTER ÉLECTRONIQUE, 2015...

Page 21: Step_10: Knobs, Shafts + Nuts
STEP_10: Knobs, Shafts + Nuts • Once you are confident that your Mutant Hot Glue is working well, the next step is to tighten down all the nuts. Be careful not to scratch the soft aluminum panel with your hard tools of course! •... -

STEP_11: R.T.F.M. • If you have not already – go check out the User Manual from the HEXINVERTER.NET website! If you’re too busy to do that, then maybe print it out and leave it by the toilet for some bathroom reading.
