LET'S START!   

Step 1:
Use a circular saw to cut the wood panels into 9 pieces in below sizes.

A:1cm*52cm x 2
B:1cm*14cm x 2
C:11.4cm*17.4cm x 2
D:17.4cm*55.4cm x 2
E:55.4cm*11.4cm x 1

Step 2:
Use a orbit sander to smooth the edges of the wood blocks.

Step 3:
Use a wood router to cut the groove on one side of bars A and B. Nail the bars together and embed the acrylic board between A and B.

Step 4:
Fasten the wood blocks C'D'E with quick action clamps and nail them into the shape of a cabinet.

Step 5:
Fasten the main body and lid of the cabinet, then install the hinges and locks with the help of the drill driver. The lid is now installed!

Step 6:
Place the items inside the cabinet and your DIY cabinet is good to go!
