I wanted to make a little bedside table lamp for my little sister. The eventual design turned out to be a sombrero LED man.
With Halloween coming up i hope it will scare some monsters away.
The design is based on two principles: easy to make and cost effective.
Total cost = $23,12
- 3w LED: $3,5
- 3w LED driver: $2,5
- 9v power supply: $4
- 12 ping-pong balls (you only need 1): $4
- Wooden beam: $6,25
- Aluminum bar: $1,87
Step 1: Materials and tools
- Wooden beam (3.5 cm x 1 cm x 173 cm)
- Aluminum flat bar (3 cm x 4 mm x 16 cm)
- 3w LED
- 3w LED driver
- Power supply 12v
- 2 screw bolts 3 mm
- ping-pong ball
- Super glue
- Wood glue
- Wood paste
- Jig saw
- Sand paper
- Wood clamps
- Drill bit: 2,5 mm, 7 mm, 22 mm, 25 mm
- Hole saw 90 mm
- Solder iron
- Thermal paste
Step 2: Sawing and gluing
Start by sawing the following pieces of the wooden beam
- Saw two 18 cm pieces
- Saw two 25 cm pieces
- Saw three 19 cm pieces
- Saw three 9 cm pieces
- Saw one 3 cm piece
Saw the 25 cm pieces into three lengths 11 cm 11 cm and 3 cm
Saw every piece in a 45° angle.
Saw the 18 cm pieces in to two lengths at 9,5 cm.
Saw every piece in a 60° angle.
Glue the three 19 cm pieces together and saw a 80° angle off at the end of the piece.
Step 3: Drilling
Drill a 22 mm hole (5 cm deep) on top of the right-angled side of the 19 cm piece.
Drill a 7 mm hole on top of the 22 mm hole almost all the way through.
Drill a 7 mm hole at the long side 4 cm from the bottom.
Step 4: Gluing
Glue the two 11 cm and the 3 cm pieces together.
Do this twice, these will be the legs.
Glue the legs to the 19 cm piece.
Glue the two 9,5 cm pieces together.
Do this twice, these will be the arms.
Glue these pieces to the 19 cm piece.
