Hi I was wondering how you connected up the power supply to the monitor? mine arrived today but I have no idea how to wire this thing up, I want to connect it to a standard power supply, how can I do this?

I used my IPad to view the Pi with two methods:

1) Using tightVNC and the tightVNC ipad app.

2) Plug the Pi into the sling Box and then transmit it to any client running the slingbox client.

It's not nearly as small, it does cost a bit more, and you have to hack a few cables, but other threads in this forum have mentioned using the Motorola Atrix 4G Laptop Dock. The upside is that the screen on this device is connected to the Raspberry Pi via HDMI, plus you get a keyboard, a trackpad, and a battery built into it. I'm sure most people here have seen the youtube video for it from Adafruit.

FYI - a very useful component is Adafruit's RCA male-male coupler which removes the need for a seperate RCA cable:

I used it in my portable Raspberry Pi.

I picked up a fairly cheap 4.7" Color LCD with nice looking plastic surround, a decent amount of changable values via onscreen menu and 3 buttons on the rear of the unit (Brightness, Contrast, Sharpness, Hue etc..) and it has 2 RCA Composite inputs. It cost just £39.99 GBP (~$55 USD) with free next day delivery here in the UK from my main and favorite componants and misc parts supplier who had bought in 10 to see how they sold and sold out in an hour.

It is designed for use inside a car and the plastic stand with strong ball joint holding it to the main unit has a sticky pad on the base to mount onto a car dash or console at various angles.

The two seperate inputs are pretty cool, the unit has 3 leads, 2x RCA female (AV1 and AV2) and a center pin positive 4mm power connector which fits in the back of the display and has about 3ft of cable then 2 cable ends that you can either add connectors to or just connect to your choice of power supply. Its rated 12v but I dropped it right down to 5.5v and it still remained operating and turned on and off perfectly.

AV1 is designed to have things like in-car DVD players and such plugged into it and AV2 is designed to have a reversing camera kit hooked up to it, so AV2 automatically comes on taking priority (which you can then switch back via one of the buttons on the rear) when it detects a signal on AV2 (in its designed purpose a rear camera system sending its output when the car is put into Reverse) on my bench I use AV1 for my Pi but its nice knowing I have a spare input for either a 2nd Pi or another input from something else.

The image is not perfect but it is fine for most things and extremly handy for when my main PC and screen are busy or off and I need to do a quick diagnosis or change a setting or even for writting short amounts of code or text (not too much though as your eyes would start going funny looking at the thing for too long!) Its far better then I expected for the amount of money paid.

I beleive that Adafruit are stocking similar displays in a range of sizes.

My Pi should arrive tomorrow. I bought a ~5 in. B/W analog TV from CVS for $17. It has RCA inputs and pretty good resolution. It also has AM/FM and will run off car's lighter socket or D batteries for portable use. Anxious to try it with the Pi. I'll report back. It may still be possible to find some of these little TV's around. Maybe a color set would be neat!

Interesting that we have the same monitor. I haven't found anything less expensive though. I just wanted small, to fit on a shelf.

Not quite inexpenisve (54.99$ +34.25$ shipping) but maybe interesting anyway... I used the myvu solo plus ev video-glasses... quite funny and still working on finding a good resulution setting.

I have a 9 inch monitor from an old mini laptop. I also bought a lvds controler from e-bay and I am planning to use this monitor and the r-pi as a car pc. Screen resolution goes up to 1024x600.
