INTRODUCTION

hank 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.

his assembly manual will show you how to build your Mutant Hot Glue module in the eurorack modular

format. his project is designed as a eurorack module and thus there are no provisions made for other

formats, though, adapting is not impossible for the skilled builder.

The Mutant Hot Glue is not especially difficult to assemble, but, you will probably benefit from having a few

DIY projects under your belt before beginning on this one.

The regular assortment of hand tools are needed: a 2.5mm hex allen key, various sockets, a knurled nut

driver for the jacks, solder, a good bench-top soldering station (50 to 70W recommended). Besides that, a

relatively accurate digital storage oscilloscope (DSO) makes calibration of the compressor circuit the most

accurate, but you could also use an O’ ool or other DSO alternative, without too much of a difference.

A huge thank you to Hannes Pasqualini of papernoise.net for his excellent graphics design and artwork used

for this project! (http://papernoise.net)

EURORACK KIT ASSEMBLY

I recommend following the steps outlined here if you haven’t built many modules before. If you are an

experienced builder, you could probably just give a read through these steps to catch any possible traps

ahead of time.

If you are building a PC +panel set for which you sourced your own components, please note

that your parts may not exactly match ours shown in the following procedures. Because the

Hot Glue is a full kit project, our focus will primarily be to aid the kit builders in this manual.

We’re going to be assembling both of the PC s at the same time, so get your tools and parts

ready and let’s go!

STEP_00: Resistors Diodes

HEXINVER ER ÉLEC RONIQUE, 2015

•First, install the diodes. The band on the diode matches the band on the PCB silkscreen.

•Diodes are polarity sensitive. It is critical that you install them the right way or the circuit will not work

properly!

•It’s a good idea to set aside your resistor lead clippings for later when we install the test points

•Next, install the resistors. he resistor colour codes for 1% metal film (as supplied in the kits) are as follows…

STEP_01: IC Sockets

•Install the IC sockets, being careful to orient them correctly. I find it easiest to put a book or something else

with a flat surface on them once they’re installed, then flip the PCB and book over for soldering. his keeps the

IC sockets nice and flat while you solder them in.

STEP_02: Power Header, Capacitors Purple LED

•First, install one of the purple LEDs into its place on the MAIN PCB. The longer leg is positive (+) and must

align to the ‘+’ marking on the PCB

•Up next are the ceramic disc and film capacitors. hese are the yellow and blue blobs, and the red box. hey

can be installed in any direction

•he power connector should be installed next, making sure that it is installed in the right orientation (as

shown)

•he electrolytics can be installed now. The negative (-) strip on the capacitors must be aligned ith the

shaded (black) semicircle area on the PCB silkscreen. Just like the LED, the positive (+) leg is the longest.

STEP_03: Pin Headers

•Begin by using pliers to snap the 2x40 pin headers into (2x) 2x10 sections and (1x) 2x3 section, as shown. We

included an extra 2x40 header in case you have an accident, or some snapped during shipment.

•Install the headers in the PCBs, making sure to install the female headers on the CONTROL PC (not the MAIN

PCB). his is because the longer profile of the female headers will interfere with component pins on the MAIN

PCB.

•ake your time checking alignment before and during soldering. You want to make sure that the

Take your time checking alignment before and during soldering of the pin headers. You want

to make sure that the PCBs line up nicely so that the standoffs+screws that hold the PCB

sandwich together are aligned properly. It might be a good idea to scre the PCBs together

hile you solder the pin headers, if you ant to guarantee they are aligned ell!

The 2x3 header is saved for the

compressor speed jumper on the

STEP_04: THAT2180, Test Points Jumper

•After installing the jumper on the 2x3 pin header we cut up in the last step, you can solder it in for the

COMPRESSOR SPEED jumper.

•Using a couple of left over component lead clippings, bend them into a ‘U’ shape which fit in the gnd and

SYMMETRY TEST POINT locations, at the bottom right of the MAIN PCB.

•Solder in the 10k trim potentiometer for the SYMME RY ADJUS calibration point

•Finally, solder in the HA 2180 VCA chip. Be careful not to overheat it, and make sure the notch is aligned

here indicated!

STEP_05: Take a break!

•It is almost time to assemble the control surface (yay)!

•But, first: look over the two PCBs you just populated and make sure there are no missing or shorted solder

joints. You don’t want to put it all together and then find out you missed a few spots with the iron! If you’re

anything like me, it happens more often than you’d like to admit (I’m not actually a robot…hehe)

•If you are feeling tired or rushed, it might be a good idea to rest up before coming at it again. he control board

is for sure the hardest part of assembly and you don’t want to mess it up! So have a fresh, well-rested mind for

this final section.

STEP_06: Prepare the Potentiometers

he included BI echnologies potentiometers all need their locking clip cut off. Grab a pair of sharp cutting pliers and

clip off the little tab of metal on each pot, as shown. 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.
