Illuminator - a Key Holder for Your Home

This is a Key holder plus Lamp inspired by Marshall Jack Rack. I designed it at National Institute of Design, as a part of Materials and Manufacturing technologies module.

I used Bamboo as the primary material for the lamp and a very simple circuitry.

This can be done in 4 simple steps

• Cutting and making body
• Joining
• Circuitry
• Finishing

Supplies

For Casing,

• Hollow Bamboo Piece -1 of length approximately 200mm, and outer dia 60mm
• Bamboo Ply - A4 size 9 mm thick
• MDF sheet 3mm thick - 250X80mm
• Acrylic sheet- 200X100mm
• Super Glue

For lamp,

• Warm white LED strips - 10X150mm - 8 pieces
• wires
• AC to DC Driver
• Plug
• Electric Tape
• 6.35mm audio jack male and female

Step 1: Planning

I have uploaded the cad file of the key holder where you can find all the dimensions of the key holder.

The rendered image is the expected product.

Step 2: Cutting and Making Body

• I took a hollow bamboo of outer dia of 60mm and cut into two equal parts
• Now take a Bamboo ply and make the marking according to the dimensions
• for the front portion of the key holder, I have laser cut the 3mm thick MDF sheet. Please find the dxf file below.
• Cut the acrylic sheet using profile cutter.

Step 3: Joining

• join the bamboo halves to the rectangular bamboo ply using super glue.
• in order to increases the strength mix the fevicol glue with bamboo dust and apply over the joints.
• mark the back side of the body and cut it and glue it to the main body.
• Now the main body is done. Still, the front and acrylic sheet are remaining to stick them to the main body. this we will do once the circuitry is done.
• Take the laser cut MDF sheet and fix the female part of the audio jack to it.

Step 4: Circuitry

• Please follow the following circuit diagram for the circuitry.
• Connect two LED strips each in series to form a LED strip for one key.
• Now paste all the LED strips on the bottom of of the body as shown in the figure.
• Now Complete the circuit as shown in the figure.
• solder the circuit wherever it is necessary
• shorten the circuit of the audio jacks(male part) by connecting its two terminals.

Step 5: Finishing

• Align the front face of the key holder to the body and stick it using super glue.
• Now paste the upper acrylic cover to the body.
• Paste the bamboo slivers on the gaps if any.
• Give it a melamine coating for a polished surface
• now attach your keys to the audio jacks.
• There you go!! Your Illuminator, The key holder for your home is ready to use!!!
