This Instructable shows you how to build a projector clock. This device allows you to project time on the wall. Based on a small LCD alarm clock (not too small, instead, you won't be able to project it and to work on it), this is a good way to display current time.
Step 1: Gather the Parts and Plan
For this Intructable, the main parts you will need:
An LCD clock with a wide screen (mine also display date and temperature)
A magnifying lens (the one used to magnify pictures for example)
A halogen light bulb
A power electric source to feed your light. I used a 12V 60W light bulb, but the power source only provide 6V, dividing by 2 the provided power. A too powerful source would feeding the light would generate too much heat and burn your LCD display.
A fan to evacuate heat generated by the light in the box
A box that you can easily work out (maybe avoid wood since heat could cause it to burn
Other: electric wires, screws, duck tape, glue and welding iron
Your first and most delicate work is to modify the LCD
