Step 2: Materials and Tools
Here is a list of material I've used to make this projector. Also a list of the tools I've used.
-LCD Screen (640x480, view)
-30W High power led (1.8A 16V, view)
-Thermal paste grease (This is to conduct more heat between the LED and the heat sink, view)
-Two Heat sinks. (One for the LED, and the other one to cool the voltage regulator)
-OHP Fresnel lens.
-Old LCD Projector Lens (If you're using a LCD bigger than 2" you won't be able to use a slide projector lens. I found the LCD projector on the street without light. Some copy lenses are good for this project)
-Some sort of case (I made mine with wood and plywood, but be creative, If you can fit everything inside some sort of metal box, that'll be even smaller.)
-40mm fan ( I took mine from a Mac case I found on the street.)
-20V Laptop charger (4.5A)
-12v PC Speakers
-4 Small washers.
- Paint (only if you decide to paint the enclosure)
-LM350 (3A Voltage regulator. Used to power the LED, view, datasheet)
-12V Fixed voltage regulator (2A, view, datasheet)
-5V Fixed voltage regulator (2A, This one is not totally necessary, I used it to make the fan less noisy, view, datasheet)
- 560 Ohm Resistor
-(2) 1N4001 Diodes
- 0.1 uf Capacitor
- (2) 10 uf Capacitor
- 100nF Capacitor
- 5k variable resistor
-Dremel with cutting disk and round file tool.
-Small round file.
-Double size tape.
