Destino Build Instructions
Hey There,
It looks like you've got your hands on a Destino module! Thanks for supporting this first product from
Haunted Pliers, a tiny enterprise that hopes to make it easier for people to get into Eurorack and grow
their synths without spending big bucks or sacrificing aesthetics. Destino is the first in what is hoped to be
a series of cool little DIY modules with very competitive pricing.
Destino is designed to be a simple and useful headphone amplifier that is easy and fun to put together.
This makes it an ideal beginner project for people who are interested in building their own Eurorack
modules. Because of this, I've aimed these build notes at novices, so more advanced builders can feel free
to skip over things that they are already familiar with.
If you are a complete beginner to soldering then I recommend you check out some online tutorials before
starting this kit. In particular, Adafruit have loads of great resources for learning various electronics skills,
such as this soldering guide:
If you get stuck or have any comments then feel free to email at hauntedpliers@gmail.com, or direct
message me on Instagram @hauntedpliers. I'd love to see where Destino ends up, so please send me
pictures of Destino in your rig to feature on the Haunted Pliers website and Instagram.
Happy Building!

Haunted Pliers, a tiny enterprise that hopes to make it easier for people to get into Eurorack and grow their synths without spending big bucks or sacrificing aesthetics. Destino is the first in what is hoped to be a series of cool little DIY modules with very competitive pricing. - Page 2 Destino Build Instructions August 2020 Tools Tools! You’re going to need a soldering iron, some solder (lead free is fine) and some side cutters. You’ll also need a small flat head screwdriver potentiometer knob. If you are interested, the soldering iron in this picture is...

Page 3: Resistor
Destino Build Instructions August 2020 Step 1 (Yeah, You Know Me) Take out the Destino PCB and flip it over to the side with the electronics symbols printed on it. This layer of print is called the silkscreen and serves as a guide to where the components will go and in which orientation. - Page 4 Destino Build Instructions August 2020 Step 3 Place the four 2K resistors into the PCB in the locations shown in the picture. Make sure you get the 2K resistors in the gaps labelled 2K. Resistors non-polarised components, so it doesn’t matter which way you put them in the holes.

Destino Build Instructions August 2020 Step 4 Place the 47R resistors in the remaining resistor holes and solder as before. Step 5 Diodes Next are the diodes, which are slightly larger than resistors. Bend the legs of these using the PCB as a guide to get the right spacing, as shown in the picture. - Page 6 Destino Build Instructions August 2020 Step 6 OP-AMP (the chip) The heart of Destino is the little chip, which is also called an IC (Integrated Circuit). This chip is contains an audio amplifier circuit. Just like the diodes, the chip has...

Page 8: Capacitor
Destino Build Instructions August 2020 Step 7 Capacitors There types capacitors in Destino. The first ones we’ll put in are the 100nf capacitors (nf = nano-farad), which are smaller than the other type. Because they are non-polarized, they can go into the PCB in either direction. -

Step 9 Power Header The power header is used to connect Destino to the power supply of your synth. It needs to go on the opposite side of the other components. - Page 10 Destino Build Instructions August 2020 Because the header sticks out quite a bit compared to the op- amp, it can make the PCB quite wobbly during soldering. In this picture I’m resting the top of the PCB on a handle of my side cutters for stability while soldering the bottom right pin.
- Page 11 Destino Build Instructions August 2020 Step 10 Audio Jacks There are two audio jacks. A black mono (because Eurorack signals are mono) and a green stereo one (because headphones and speakers are usually stereo). If you are colour blind then the stereo jack is slightly wider than the mono jack.
- Page 12 Destino Build Instructions August 2020 Step 11 Potentiometer potentiometer volume control for Destino. First, remove the nut and washer, but keep them handy. When place potentiometer in the PCB, you’ll notice that it has three regular legs and two bendy legs. These...
- Page 13 Destino Build Instructions August 2020 Step 12 Check your handiwork Your Destino PCB is now fully populated with electronic components. Doesn’t it look great? Now, it’s time to check your solder joints for any you may have missed or look bad, as it...

Now, put the knob on the potentiometer so that it points between the D and E of ‘Destino’ and tighten the screw. This will make the sweep of the volume knob symmetrical. DONE! Finished And that’s a wrap! Pat yourself... - Page 15 Destino Build Instructions August 2020 Finally… Connect the Power Now that we’re done it’s time to connect the module to your power supply and add it to your Eurorack system. Make sure you insert the connector so that the red wire is next to the ‘RED’...
