Build Instructions
Inside you will find all the parts required to build your own EDU-DI. Use this document to assist you as you begin to
build your own direct box.
Basic Instructions:
1. RESISTORS: Start by placing the first resistor (R1) in the
designated position. Bend the wire leads at 90 degree an-
gles to feed the leads through the board. Spread the wire
leads slightly to ensure the resistor stays in place. Solder
the leads from the bottom of the board, then clip the excess
wire leads. Repeat this for the remaining resistors R2-R5.
2. CAPACITORS: Place the first capacitor (C1) in the as-
signed designation. There is no polarity so you may install
these in any direction. You do not need to bend the leads
to fit, however after it's been inserted you can bend the
wire slightly to secure in place. Solder the leads from the
bottom of the board and then clip the excess wire leads.
Repeat for C2.
3. PUSH SWITCH: Place the first push switch (S1) in the as-
signed designation. Make sure it is facing outwards from
the board, flip the board over and ensure the switch is flush
to the board, then solder the 8 pins. You do not need to clip
the wire leads. Repeat for the remaining switches S2-S3.
Soldering Hints:
1. Mount the component against the
PCB surface and bend the wire
leads slightly.

2. Solder the wire leads from the bot-
tom, make sure the solder joints are
cone-shaped and shiny.
