upside down joggler

slightly wierd request

I'm running a Joggler with Squeezeplay OS
I want to mount it under a cabinet in the kitchen and rather than building a hanging shelf to put it on the easiest way would be to flip it and attach it upside down

Is there a way to flip the screen in software ?

regards

Glen

Might be better to post this in the Squeezeplay OS thread ;
SPOs is a stripped down version of Linux as far as i know so it could be possible .
Failing that you could use Linux Mint and rotate the screen from within that and them get Squeezeplay to aoto boot on start after that ( almost Squeezeplay OS

)

I found this below but am not sure if invert means rotate 180 degrees

Under Linux, the following commands will rotate a laptop's builtin screen (I think it usually gets named LVDS1):
Code:
xrandr --output LVDS1 --rotate normal
xrandr --output LVDS1 --rotate left
xrandr --output LVDS1 --rotate right
xrandr --output LVDS1 --rotate inverted

Good luck

Thanks i'll give that a go.

going to be moving away from dedicated Squeeze OS anyway to squeezplay running on Linux, as i want to try making the Joggler also a Mythtv Frontend. So this might be more easily doable that i first imagined

I've never taken a Joggler apart.......................yet!

But is it possible to split it and just rotate the screen 180 degrees?

Have a look at this video at about 2 minutes it looks like there is plenty of slack in the cable to accommodate this if it was possible to clip it all back together again....if you know what I mean

interesting idea
it would get around the boot logo being upside down before it hit the configuration file too.
worth investigation

cheers

You can't spin the screen around and reattach it. There are clips at the top and four mounting posts on the bottom. It would never go back together without some considerable butchering.

Do post and let us know how the display rotation goes, though. I did consider doing this myself at one point, but then the plans changed.

another option may be to rehouse the guts of the joggler in a different case and lose the stand completely.
will try the software method first tho
the geek in me kinda likes the idea of it initially booting upside down

thought number 3
just remove the integral stand as that’s really what’s causing me the mounting issues.
could replace it with internal patch antennas from an old laptop screen (i guess this should be in the hardware forum now. lol )

Hmm remember the stand is the Heat sink as well all be it not a very efficient one so you might need to do the Thermal trip point tweak if you dont want the Joggler to start throttling very quickly

.
The Raspberry PI comes without a heat sink and plenty of people are selling them on ebay , they stick on with thermal tape whatever that is lol .

maybee you have something similar in the bottom of your "man drawer" .
Keep us posted .

Good call. Didnt consider that

I wondered if this would work as hanging the Joggler under a kitchen cupboard would be quite neat. This is what I tried once I'd SSH'd in:

Code: Select all

joggler@joggler:~$ xrandr --output LVDS1 --rotate inverted
Can't open display
joggler@joggler:~$ export DISPLAY=:0.0
joggler@joggler:~$ xrandr --output LVDS1 --rotate inverted
warning: output LVDS1 not found; ignoring
joggler@joggler:~$

So, even though it didn't work, the good thing is that xrandr is in the build. I'm not really sure what the "output" is - for the display lspci shows:

Code: Select all

00:02.0 VGA compatible controller: Intel Corporation System Controller Hub (SCH Poulsbo) Graphics Controller (rev 07)

The xrandr man page says:
--output output
Selects an output to reconfigure. Use either the name of the output or the XID.

I don't know what the SqPOS root password is so couldn't check the messages log for clues.

If anyone has an alternative suggestion I'll give it a go and report back.

Oh, and I just tried this too:

Code: Select all

joggler@joggler:~$ xrandr -o inverted
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  151 (RANDR)
  Minor opcode of failed request:  2 (RRSetScreenConfig)
  Serial number of failed request:  14
  Current serial number in output stream:  14

I don't know if this error means it can't be done.

Admittedly a low tech solution but I've mounted one under a kitchen cupboard the right way up using a flexible arm satnav windscreen mount attached to the Jogglers metal stand.
The flexible arm also provides something to zip tie the cables to to neaten up the installation.
Works quite well and I'm pleased with appearance - see pic.
It's connected to an Ixos Divo sound system with sub and satellite speakers hidden on the tops of the cupboards.
This system has a separate iPod dock which houses the receiver for the remote control.
We don't have iPods so I've positioned the dock on the top of the cupboard and the bluish led display complements SqueezePlay so it looks as though the two come together.

@fishy: that looks great. Would you consider posting photos of the back showing how you have set it up?

Fishy · Post by **Fishy** » Fri Aug 10, 2012 10:49 am

Here's what it looks like from behind - perhaps not the prettiest but it's all hidden by the screen from the front anyway.

1) Disassemble the suction part of the windscreen mount. These usually work with a centre pull to create the vacuum when you stick it on the windscreen. Disassembly leaves a nice hole through which to bolt the mount to the cupboard.
2) Use a coach bolt to attach to cupboard. These have a flat rounded head so won't snag your cornflake packets in the cupboard! Must admit I need to trim the bolt down now but left it long at the time because I was thinking might attach something else to hold the speakers remote control when not in use.
3) Remove claws mechanism that grips satnav from other end of mount. That revealed a flat plate with 4 holes in it that luckily matched up nicely with the flat width of the Joggler stand. So simply used cable ties to attach the two. This was at "proof of concept" stage (!) and did think would drill the stand and use nuts and bolts for this later but actually cable ties are fine so I've not bothered to change them.
4) Used a cable tidy from Maplins to trunk the power, ethernet and headphone wires into the space behind the cupboard and upwards to the location of the speaker system.

The whole thing is quite sturdy.
There is slight "give" in the satnav arm as you press the screen but it actually complements the touch screen action rather than hinders it.
Overall effect looks good I think (wife happy), frees up workspace and gets the Joggler away from cooking debris!!

Nice job
are you using the mount to actaulty hold the bar/stand rather than case of the unit itself ?
i've been looking for a sat nav type mount for mine and either they are not wide enough to hold the unit or obstruct the power/audio/USB ports

Yes, the mount is attached to the bottom of the Joggler stand not the unit itself.
Thus the sockets are not obscured.
The satnav mount was a generic one with expanding claws to grip any satnav.
I removed the adjustable claw section from the satnav mount.
That left a flat plate with 4 holes in it.
Then zip tied that to the base of the Joggler stand.
It was a bit tricky because the mount arm had to almost double back on itself so the flat plate married up to the Joggler base - you can see the metal inner of the arm showing in the picture as the plastic outer slid back slightly bacause of the extreme angle.
However once done it's fine and as I said previously whole thing is sturdy enough to do the job well.

Thanks for compliments!!

Clever use of stuff designed for other purposes. Nice one.

If you don't mind rebuilding the IEGD, it has a "rotate" option, which does it in hardware.

Rebuilding the driver which displays the O2 logo on power on is a little tougher though, tried it a few times and the results were nasty.

is the "Goose neck" strong enough to hold it without bouncing around when you hit the touch screen ?

hmm, You got me thinikng now something like this

combined with desk mount plate might do the job
