Erica Synths EDU DIY Wavefolder Eurorack Module Kit - Manual (Page 53)

53
Congratulations! You have completed the assembly of the mki x es.edu Wavefolder
module! Connect it to your eurorack power supply and switch it on. If there’s no
"magic smoke”, it’s a good sign that your build was successful. Patch the sawtooth signal
from the DIY.EDU VCO to the SAW-TRI input of the module and connect the OUT of the
module to a mixer. You should hear some sound which timbre will change as you adjust
the INTENSITY knob. Now you can proceed with calibration, which consists of adjusting
the multiturn trimpot. Please, follow instructions above!
Enjoy!

If you’ve never soldered before – or if your skills have become rusty – it’s probably wise
to check out some THT (through-hole technology) soldering tutorials on YouTube.
The main thing you have to remember while soldering is that melted solder will flow
towards higher temperature areas. So you need to make sure you apply equal heat to
the component you are soldering and the solder pad on the PCB. The pad will typically
absorb more heat (especially ground-connected pads which have more thermal mass),
so keep your soldering iron closer to the pad on the PCB. It’s critically important to dial
in the right temperature on your soldering station. I found that about 320 °C is the opti-
mal temperature for most of parts, while for larger elements like potentiometers and
sockets, you may want to increase that temperature to 370 °C.
Here’s the recommended soldering sequence:
After you have completed soldering, inspect the solder joint:
