Yeah, getting the video from the RPi to computers or TVs wouldn't be a problem, but I'm kind of hesitant to even try to weatherize the RPi itself. My house is in the woods, and the canopy seems to trap humidity.  It gets VERY humid here.

  My biggest problem is that I have too many projects.  I never finish anything.

Unfinished projects keep one alive.[cool]

Yep humidity might be a problem, in the 70's I did some TV work for Day's in Portland,Maine. We could always tell when summer had arrived. Flybacks in the TVs would breakdown and snap and crackle and finally disable the TVs.

I would experiment with enclosure so it doesn't trap moisture. Mount the RPi on edge so moisture can't collect. Fans would help also. Dessicants wouldn't hurt either. You've probably played with all of my suggestions, and others also. If the fan works that might be the best route as it would also be beneficial as a heat mover .

  I am going to plug my Pi camera into RPi2B with 4.1 kernel the one that DarkSky has on line. Hopefully I can get some good results.

Ok I have added my iq_modcod to my desktop.Screenshot - 07032015 - 03:53:25 PM.png 

I am not crazy about the icon.
I looked at what people said about alacarte and icons and I can't seem to find the 
hidden files they talk about. Any suggestions.



The screenshot I took was of 11990 H 8000 at 87 W it is the only signal I have of MODCODs greater than 32APSK 3/4.
The iq_modcod progam will work in conjunction with updateDVB and tune-s2 and you must be running STV090x drivers. In fact maybe only STV0900 demod don't know if STV0903 will.
Anyhow STV0900 is a very powerful demod and I am just trying to find out how useful it is.

The other thing is that RPi2B is [cool]

this is what I made for an icon...
Think I mentioned it a while ago in the updateDVB thread.

You will have to activate the camera in raspi-config and reboot.

I find my icons by searching for free icons on the internet.

Hooked up the powered USB hub and tried to do a scan with the inDtube.  Way too much pretty rainbow in the upper right corner time and the Pi froze.  Hub will be returning to its former owner soon.

Also noticed that iceweasel and the noMachine processes are both CPU hogs.  They each idle around 10% and peak around 27%.

As stated in the updateDVB thread, I think blind scan is the better tool for ATSC scanning.  Spectrum scanning isn't reliable.  Also think the Pi isn't the best machine for scanning.  I still like it but there are drops.

Doing these replies with iceweasel and noMachine.

I never have been a big fan of using remote desktops on the local lan. Things slow down too much for my liking here using my desktop computer. I wonder if VNC would be better.

Back when I was helping signalquest get his kernel and updatedvb set up remotely. UDL suggested using ssh with compression and xforwarding which sped things up considerablly with the graphic transfers. It popped up a window only with the single program running instead of the whole desktop.

I enjoy watching tv using my 950Q atsc tuner with everything native on the pi. There is really no problem scanning or watching tv other than the occasional issue of my newer firmware than the others have here that I have to use; which I have learned to live with. I have noticed that things slow down with using a slower read / write sd card. I really have no need of screen or window  transfers of any kind here locally.

Majortom uses screen for ssh but I never got around to learning that terminal emulator so I use the terminal that comes with the OS's which has the capability of having multiple tabs to log in with.

Here is me using ssh with xforwarding and compression with my pi from my desktop. I opened up updatedvb and pcmanfm from two ssh logins to my pi. Only the windows pop up with the programs I am running on my desktop machine.

'screen' isn't an ssh client.
It's just a way to have several 'screens' open and running in the background for easy retrieval with just a few keystrokes. It's main benefit is when you are running an ssh to a remote server, if the link dies for whatever reason, the process(es) that you had running on the remote via that session, won't die when ya lose the connection for whatever reason....

Thanks majortom.

That just proves in my statement above was true, I never got around to learning it. LOL

It looks like it does have some benefits though.

Question with using screen:

Things seem to me on screen transfers or even data in the terminal with ssh everything slows down to sync between the remote and the host. Could be my imagination.

If I understand you right say if I ssh to the pi and with using screen to compile a kernel or qt and get it started. I could log out and log back in later?

exactly...
example:
1. ssh to pi and type 'screen'
2. start compiling on pi
3. type ctrl-a d
to detach that screen
4. logout of that ssh session (whatever you started with screen will still be running)
5. to go back and see how it's doing
ssh to pi again..
resume that screen with
'screen -r'
if there is just one screen to choose from, it'll just take ya right there,
if there were multiple screen sessions that could be resumed, 'screen -r'
will provide a list of them like this

screen -r
There are several suitable screens on:
        2307.pts-10.perseus     (07/04/2015 12:44:57 PM)        (Detached)
        13792.pts-2.perseus     (07/03/2015 05:05:54 PM)        (Detached)
Type "screen [-d] -r [pid.]tty.host" to resume one of them.

if I wanted to resume the one from yesterday I would then
screen -r 13792.pts-2.perseus

You can do all sorts of fun stuff with screen, for example rename them to something more meaningful...so on...
There's probably a guzzillion 'guides' to read on the subject of screen, but really all ya need is (and all I use)
'screen' by itself will create a new one...
'screen -r'  to resume one
and 'CTRL-a d' - to detach one
to terminate an existing screen, just type exit from within that screen

Thanks, works good but I do not think xforwarding is practical. The terminals work great.

I can see a use for xforwarding for something like updateDVB or other graphic programs but agree that when all you need is a terminal; screen could be the answer.  I only play with noMachine because it's useful for me when I travel.  I download all my email to my desktop because I don't like using someone else's server for me to store it or read using a browser.  I'll have to do some more ssh reading.  It's my login of choice.

Ssh forwarding also only forwards video, not audio [frown] nomachine does both. Last I read nomachine was hoping to utilize hardware mpeg compression/decompression on the RPI in the future, that'll defn help with the CPU usage.

That looks like a mess.
Right click on the unknowns and choose delete if it will let you.  When you wind up with just one unallocated right click on it and choose new.
primary
fat32
Click Apply All operations arrow.
close out gparted and eject and reinsert card

It may tell you to create a partition Table. Click on Partition on the menu bar and choose msdos

It looks kinda like you did not cleanly unmout after writing the image or left out sync.
You can always shutdown the computer and reboot each step. Linux will do the rest for you.
The card needs to be cleanly ejected and reinserted each time the file system is changed


Gparted came installed on the Pi? Or should it be installed? Which version for the Pi?
