I wanted a new table lamp, but found a regular table lamp rather uninteresting. I wanted to create a lamp with which it is possible to readjust the shape and size.
The table lamp exists out of eight cubes, with which you can build different shapes. Each cube has four bright 0.5 watt straw hat LEDs inside.
This lamp was easy to make, but consumes a lot of your time.
The light output depends on the total amount of cubes that you use. If you use just one cube you have little light (for example as a night light), if you use all the cubes you have more than enough light to light up a room.
The overall cost of this project was low, except for the neodymium magnets (40 $), which seem to have risen in price the last year.
Step 1: Materials and tools
- 40 0,5W straw hat LEDs
- 8 bridge rectifiers
- 8 6.8 Uf > 12v capacitors
- 16 39 Ohm 1W resistors
- Conductive silver
- White acrylic sheet
- 192 nails
- 192 6 mm by 5 mm round neodymium magnets
- 12v power supply 2 amp
- Toggle switch
- Wooden board (9 mm thick)
- Wood glue
- Super glue
- Jig saw
- Miter saw
- Sand paper
- Wood clamps
- Drill bit 3 mm, 6 mm
- Hole saw 67 mm, 74 mm
- Solder iron
Step 2: Sawing, drilling and gluing
Saw 48 squares of 10 cm by 10 cm out of the wooden board.
Saw a 45 degree corner off each side of each cube.
Draw a cross in each square and make a mark 1.3 cm from each corner. Drill a 3 mm hole in each mark, and drill a 6 mm hole 3 mm deep on top of that.
Drill a 67 mm circle in the middle of each square.
Use wood glue to glue five pieces together so that you get cubes with one side missing.
Step 3: Drilling acrylic circles
Saw 48 74 mm circles out of white acrylic using a hole saw.
Use super glue to glue the white acrylic circles on the inside of each cube and on the eight remaining squares.
