Introduction
With some lenses, a small LCD or TFT screen, 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.
2.2" TFT
insctructable for the screen I have. This screen died :(
Old stuff for Nokia display
- Information on the display: serdisplib
The one I've got is a 'type 2'.
- Connecting the display to a Raspberry Pi: [1]
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.
