MIDI THING V1 - ASSEMBLY GUIDE
FEMALE PIN HEADERS
Place the two female pin headers “JP100”& “JP101” and solder them where the
silkscreen indicates.
SPACER
Secure the spacer onto the Control PCB (through the hole with silver outline) with
the main body of the spacer on the component side, and the nut on the opposite.
FRONT PANEL COMPONENTS MOUNTING TIPS:
Now we will proceed to mount the jacks, potentiometers, switches and LEDs. This part of
the assembly is CRITICAL. Please take your time and read the following instructions
carefully.
These components must
NOT
be soldered until they are placed on the PCB and fully
attached to the front panel.
There are two reasons for this:
•
The height of the panel components are not all the same. Because of this, if not
attached properly before soldering, they will not stay properly seated against
the panel. This might cause mechanical stress reducing their life expectancy and
in the worst case cause them to break.
•
The second reason is that it is very difficult to align the components to the
holes if the panel is not positioned prior to soldering. In the case of the LEDs,
they are almost impossible to set to the correct height without reference to the
front panel.
LEDs
Place the LEDs onto the PCB minding, their polarity, but
don't solder them
until the
front panel is in place. This is the only way to solder them in the right position.
The long leg is the positive and the short the negative. On the PCB the square pad
indicates the negative side and there is a + symbol to indicate the positive.

MINI-JACKS
Place all the mini-jacks onto the PCB ensuring they are on the silkscreen side, but
don't solder yet
.
Caution:
the switch nut and the jack nuts look the same, but they are not equally
sized and will not fit in each others' thread, so make sure to keep them separate!
PUSH BUTTON
Place the push button on the PCB where the silkscreen indicates but
don't solder
it yet.
