Pre-purchase questions.

Sun Aug 04, 2013 12:17 am

Hello! Looking to buy me some Pi! Got some rough use-cases in mind for my two Model B's I plan to get, now I'm just full of questions. Let's dive right in, shall we?

First off, I'd like to use one as a children's computer, as the VAIO they used to use has gone RIP. Poor old thing, bout time it fried. One thing I see a lot of issue about is flash. The kids love their flash games, especially bearville.com. Is there /any/ usable setup for flash? Even if it's android.

For the second Pi, it will be a miniature wireless network camera setup with battery, moonlighting as a RasPlex. Now, RasPlex is easy enough, just put in the card with RasPlex installed, but the camera is concerning me.

I intend to get the RasPi Model B, with this Wifi dongle http://amzn.to/1ejJI9C , and the camera board.
Now, what would be the best software setup for this thing to run like a DVR, saving video all the time or on motion sense, and save it to a NAS? Also to stream live when I want a peek? Zonealarm? "Motion"?

And, keeping in mind the above hardware power drain, would this battery suffice? http://amzn.to/13wmziM And about how long do you estimate it would last?


I'll reply to this thread if I get more questions!

A partial answer to your questions!

Flash is a dead horse on the Pi so if that is one of your requirements then the Pi is the wrong device. There are attempts (e.g. gnash) to provide an open source equivalent, but it is buggy, incomplete and suffers from terrible performance.

For 20 $ more you'll get a Android TV stick which all seem
to have Flash. Of course the Linux community isn't comparable
to the Pi , but Ubuntu should technically run on those things.

The battery pack should power the Pi for 5 hours.

Thanks!

So I may go with this battery http://amzn.to/16lUgSJ then, 5 hours is too short for my needs.


Also, the monitor I intend to use for the kids does not have HDMI, just VGA, DVI, and DisplayPort. So would this cable work? http://amzn.to/bjGGF7 Not sure about any power drain or anything like the VGA adapter I was looking at.

If it has DVI-D input , not DVI-A it should work.

That cable should be fine, actually thats useful for me, I was looking for one of those too! (I have an HDMI monitor though - you should invest in one if your getting a Pi).

I have the Easy ACC power supply you mention and it works great. The Pi will only draw 700ma max so you'll get over 12 hours with it.
The DVR software I would recommend is MythTv, I have seen references saying it works on the Pi.
You will just need to mount the NAS drive as part of the file system and tell Myth where to save the data

Aye, but it's been suggested the WiFi will be the main drain, and the camera isn't electricity free, so it might draw more than that?

Also, I meant camera DVR :) MythTV is more for, well, TV I think and I would have to get a tuner.

So one more hardware check before I get to shipping, the other Pi is going to be on a plug, I've been told not to go for cheap generic phone chargers, so how about this one? http://amzn.to/194Bm8S

Myth can take any sort of input it mainly gives you control both locally and remotely. If I were you I would check it out anyway.

As for the charger, I would go with something that has more power or at least one you can be sure of the amps it can provide. The easyacc power supply you have chosen does not come with a charger either.
You can run the Pi with a charger that delivers more the 700 milliamp but I would include a little headroom as over time the parts degrade and you loose a little power.
The easyacc battery really needs a 2+amp capable power supply if you want to charge it in a reasonable time frame

High amp chargers aren't expensive and you won't damage anything by going little overboard.

I would go with a powered hub as well. You can plug the wifi dongle into it and draw less from the Pi. It also means you can use bus powered hard drives and more power hungry gadgets. You can get powered hubs that have "charger" ports that allow the current to go above the USB specs of 500ma, usually up to 2 amps to charge tablets. If you get one of these you can power the hub and used the charger port to power the Pi. It gives you extra juice and only a single wallwart

Quick question from another noob. I have a TON of videos I've saved off of Youtube, Vimeo and others.
Most of these are in .flv format. I understand that to be flash. I set my Pi up as a media center,
will I be able to watch these videos? I was hoping to be able to watch all of these on
the family TV.

I would feel terrible for your kids if you buy them a Pi as a computer to play on. Recently, I just sold an old but 100% running windows XP machine for $50. With all the add ons that you would buy for the PI just to make it work as a game device for the kids, put all that money together and hunt for a pre-owned and working real PC on craiglist like this one: http://buffalo.craigslist.org/sys/3916717354.html

As for you camera Pi project... i wish you all the best! :)
