guitar string
9 screws
2 pins
disposible camera circuit
9v snap

Step 1: Cut the Wood

this here is just the basic construction of the frame
first cut the ply wood to 2 bits 10 cm long and 1.5 cm wide and 0ne to 5 cm long and 1.5cm wide

then cut the mdf to a 5 cm square you will be needing 2 of these as well

Step 2: Frame

assemble half of the frame but keep a piece off the mdf off
and screw or glue together

Step 3: The Circuit

for this step you will need your soldering iron and solder
your camera circuit and some wire
a pair off pliers also can help

then take off the capaciter and solder two other wires
and on the wire butten on the back you will need to put a blob of solder on that

Step 4: Screw on the Next Piece of Mdf

leave the wires hanging out and put the two front wires on the pins 1.5 cm froim th top
