Re: R-Pi inside LCD - all-in-one computer for sub-$150 including accessories

Tue Mar 06, 2012 3:06 pm

Here's the thought:

R-Pi B is $35

Cheap, but brand new 19" LCD is $89

8GB SD card is $8

You can get a decent basic keyboard and mouse for less than $15

That brings grand total to $147 - and that's retail prices.

R-Pi is small, it can be put quite easily inside LCD, especially if it is built-in by design (LCD manufacturer cooperation required ofc) you'd have a single box, with a single power supply etc and with the bulk purchases discounts you could easily offer full computer set for less than $150, it might be even possible to go as low as $129 or even $119.

Schools (among other institutions) would definitely be interested in buying it, especially if getting 20 computers for the class would be a sub $2500 expense.

I actually think this is a bad idea because then the RPI and the monitor get obsoleted together. The RPI is going to be obsolete much faster than a monitor will.

Doesn't have to be the only input to the monitor.

And of course the RPi might be "obsolete" but it will still work as fast as it ever did...

How exactly are you going to get schools to use the GPIO etc if its in a monitor ?? just a thought

Sure, but I don't understand why anyone would go through the effort to make a custom LCD case with the RPI included. (keep in mind, effort -> cost)

Just choose any LCD, get the RPI with a case (which will not cost more), and then get some double sided tape and stick it to the back.

Now you have the same thing, but with lower cost and less sillyness.

Nice try, but you probably have to add in HDMI cable - $10 plus a micro USB power supply - $10.  You might find a monitor with a built in powered USB hub, but that would push up the price of your monitor.

Instead of mounting your R-PI inside the monitor you just need to fix it on the back of the monitor, probably using the 75mm VESA mount holes and some M3 screws.

You misunderstood me.

I am not talking about a single unit being built in someones basement, the idea is to create a complete computer set, ready for mass production (as in more than 1k units/batch) in cooperation with LCD manufacturer.

Another option (from a negotiation standpoint, result would be essentially the same) is to try to get one (or more) to introduce new line of LCDs with R-Pi built-in. "Can be used alone as a fully functional computer" would get them a few sales for sure.

Just as R-Pi is a $25-35 computer this would be a ~$120 complete computer set with display, storage and input devices – no extra purchases necessary. Unbox it, plug the included keyboard, mouse and power cord and you're ready to go. It seems to be the next logical step after R-Pi B.

It might even be a real alternative to OLPC in some cases.

Reasons:

1. Because the combined system wouldn't sell enough to interest the monitor supplier, and the customers probably want different size monitors.

2. Because the monitor supplier wouldn't want the success of their product to be tied into the success of the R-Pi (their unit costs are actually far higher), and they wouldn't want to have to warrant/support the R-Pi.

3. Because the price of monitors is falling and technology is changing, so R-Pi manufacturers and buyers might not like being tied into a particular screen format/technology.

4. Because you can get the same convenience and no extra risk of obsolescence by sticking the R-Pi on the back of your preferred monitor, which only needs to be HDMI compatible.

Of course a big advantage is security - it would be very easy (and attractive) to pick up the RPi box, slip it into a pocket and walk off. Trying to do the same with a monitor is more of a challenge.

Similarly having a single device from a single supplier makes warranty issues easier - separate manufacturers can have a habit of blaming each other.

There is a trend towards internet enabled tvs, these are basically a computer embedded in them with restricted UI, a standard platform with a community to steal worok from (sorry inspiration) may produce cost savings in development that would outweigh the cost differential from unneeded chips on the RPi. Though if a true monitor manufacturer they could just use the parts of the design they want directly on their controller boards and it would end up not really being a RPi.

Yes, that would be the best security you can have.  Much better than leaving it lying around or inside an LCD, from where it could be removed with simple tools (screwdriver, pliers)

From my experience unscrewing the back of a monitor and taking it apart will generally take longer than a matter of minutes and would likely be noticed by even the most distracted teacher in a classroom environment.

It's not foolproof or military grade but it does raise the bar substantially higher than for bored opportunistic casual theives and pranksters.

I was working in a bank in Hong Kong back in the days when PC boards were worth quite a bit more than they are today, when somebody stripped the innards of all the PC's in one department. Ironically it was the IT audit and security department.
