I've got a bit of a dilemma on a projector we have installed in our new restaurant.. It's up with power on but I'm not sure if the best way to project our menu from it..
It's a reasonably old Mitsubishi projector the that's come out of my boardroom at work, we are trying to use it to project a live menu, the problem being the computer that has the menu on is in the office the other side of the building approx 20m away.
So far as I can see the options are to run a cable (not ideal as it will be difficult), get some sort of wireless device? Or put another computer closer (seems a waste!).
For info the usb slot is the old type b one.
If anyone has any suggestions or knowledge on the subject would be greatly appreciated...we open on Thursday!

You could try this but the reviews aren't great but as it's amazon if it is pants you'll have a easy return

If the projector has hdmi then this might be better?

But if it has hdmi perhaps you could use a chromecast, I've never used one but perhaps some other members have experience of them that's relevant?
A quick google sounds like chromecast could work...

Strap a raspberry pi or similar to it.

Chromecast hdmi receiver. Send what you like to it.
Thanks guys, I'll look into all of them.
Someone else mentioned a raspberry pi, no idea what they were talking about!
What video connection do you have at each end? VGA/DVI/HDMI?
What video resolution are you planning to use?
Is there a network cable near the projector?
Can you get a CAT5/6 cable connection between the PC & the projector?
This is a great suggestion.Originally Posted by fornowagain

We have rgb and usb on the projector,.
We've bought the chrome cast and that has hdmi ... Looks as though there are cables that convert it but not sure if I need anything else?
I've tried just putting something in the usb but that won't work.. I think it has to come through the rgb connection.
No network cable close or easy route so went for the chrome cast..
The USB port is probably not for transmitting an image; more likely some form of management. Have you got a model no or a picture of the back? I got an old cinema projector working from an office of ours that closed but that was relatively straightforward - but it was a long time ago.
You need a small box to convert the digital HDMI signal to analogue RGB format; the cables you see on places like Amazon do not do that. This box is the best seller on Amazon but it converts to YPbPr format, which is close to RGB but not quite the same:
http://www.amazon.co.uk/Portta-YPbPr...ds=hdmi+to+rgb
Can you check the setup menu of the projector to see if it can be set to take in YPbPr (may be called YUV).
These converters are notoriously flakey to get working so I suggest you look at Amazon as there is a good chance you can send it back if it doesn't work.
There's also the issue that the Chromecast dongle needs to get powered. I think it would normally expect to be powered from the HDMI port on the TV but I don't know if the converter boxes send power up the HDMI port.
This one on ebay is from someone who is selling up & has the cables:

A quick Google shows up a post over on Pistonheads:

Maybe PM Marshalla to see if he can point you at the unit he used.

Chromecast comes with a mains adapter which is just a usb psu, cable is a full size usb to micro usb. I have one on a small TV in the kitchen and it takes power from the TV's usb socket. It can stream anything you like, it even mirror's my smartphone or laptop's display at 1080p. Amazing device.
Try something like the HDMI2AV linked below. Usb powered and will convert and downscale the HDMI to analogue. Don't expect too much from the old projector though. Probably going to be fairly low res, maybe XGA (1024x768). What's the model number?
See if the projectors usb will power the Chromecast, if it does you might be able use a usb y-cable to power the Chromecast and HDMI2AV. Both very low current devices.

If you are lucky, PC World will be selling the Chromecast for a tiny £18 by and by.
I'm assuming that as the projector is old, it'll be fairly low res, probably 1024x768 (XGA) max. This is a good thing, as it's not going to gobble up bandwidth like HD.
I had a gizmo a few years back like this, to hitch up my PC to the new-fangled (at the time) flat screen telly.

It worked very well, although I must admit I never tried to run it at 20m seperation. You'd probably be OK so long as you've got line-of-sight or something close. It might struggle with walls in between transmitter and receiver.
The transmitter was a USB dongle, just plug into the PC. The receiver needed a wall wart PSU, and had a VGA connector for the output. It'd simply be a case of using a VGA-RGB cable, like this:
http://www.lightinthebox.com/vga-hd-...FWKWtAodFEoAtw
to connect to the projector. This one has 5 x BNC connectors on, R/G/B/H sync/V sync - if your projector has RCA/phono connectors, then you'd need a cable with those on.
If you do pick up a secondhand Q-Waves kit, be aware that they've been out of production for a while - I think the PC I was using ran XP, there may not be newer drivers available.
Cheers,
Plug
