CV Thing v1 - ASSEMBLY GUIDE rev. Aug 2021

THANKS FOR CHOOSING ONE OF OUR KITS!

This manual has been written taking into account the common issues that we often find people 

experience in our
workshops. The order in which the components are placed on the board is meant to make 

assembly as easy as possible.

Some steps are not obvious, so even if you're an experienced DIYer please read the steps 
thoroughly before starting.

If this is your first project, please read this article before you start assembling the kit:

www.befaco.org/howto/

     

You will be soldering both boards at the same time. Keeping them in the panel together, until 

stated to split them, might help you through the build. Check last pages of the Build for PCB 
pics to help you identify components.

RESISTORS

It’s strongly recommended to measure the resistors with a multimeter. Color code might be 
hard to read with blue background.

DIODES

Solder the diodes 

observing their polarity

. The black or white line on the diode must 

match with the white line on the diode symbol on the PCB silkscreen.

FERRITES

Solder the two ferrite beads by using a recycled diode leg passed through each ferrite and 
proceed as if it were a resistor. Ferrite beads don't have polarity.
