Let’s begin!
MAIN BOARD
1. Tact Switch (S1): First off, use a tiny half-drop of super glue to attach the little button cap (SW-60-
23) to the switch actuator (1,2). Make sure the cap is pressed down tight to the tip of the actuator.
Now set the switch aside to allow the glue to fully cure before you install it later.

2. Capacitors: This kit contains three types of capacitors (or caps): film, electrolytic, and ceramic. The
little yellow ceramic cap will be installed on the sensor board later. For now we will install the red
film caps and cylindrical electrolytic caps on the main PCB, one type at a time.
a. Film Capacitors: There are 3 film capacitors in the VPM-1 (C1A,C2A,C3A). They are100nF
(.1uF) in value and labeled “104J”. These caps are not polarized, meaning the leads can go
into either hole. Install these caps on the front of the board (3,4) and bend the leads on the
back so they don’t fall out (5). Solder each lead and then clip them off right above the solder
joint (6). Save two of these leads to use as jumpers later on in the assembly process.
