Introduction

With some lenses, an old LCD from a mobile phone, a bright LED and some driving electronics it should be viable to build a device capable of projecting stuff on your wall. Note: The dutch pseudo-anglicism "beamer" means video projector.

Info gathering

Some example project by someone else; is here
Information on the display: serdisplib

The one I've got is a 'type 2'.

Cabling

I could'n find a male DB25 connector so I checked whether a cable I had lying around would be useful.

Male-male DB25 (LapLink Cable?)

PCPARPORT	OTHEREND
PIN2=D0	PIN15
PIN3=D1	PIN13
PIN4=D2	PIN12
PIN7=D5	NC
PIN9=D7	NC

PCPARPORT = parallel port found on standard pc, http://edge.kitiyo.com/2009/pc-interface-logic/parallel-pc-interface-unit.html
OTHEREND = other end of cable (standard LapLink??? http://en.wikipedia.org/wiki/LapLink_cable)

Since PIN7 is not connected this isn't going to work :(

Parallel floppy cable

Next candidate was a short cable normally used to connect the floppy drive of an Olivetti Echos Pentium 1 laptop. Again: some pins that I needed weren't connected.

Parallel printer cable

This one looks promising according to http://www.lammertbies.nl/comm/cable/parallel.html I don't own the connector that fits the 36 pins Centronics connector so I'll cut up the cable and connect the wires directly to the resistors.
