Noob with a Frozen Pi. Desperate

[nickmazz]

I could really use some help all. I'm about as novice as it comes with this stuff- never done anything remotely like this- I am teaching myself as I move along.

My pi freezes when I get to a certain step.

This is what I have been doing: 1.) •Install Debian Wheezy on SD card 2.)•Run raspi-config, Expand the root file system, overclock, set to boot up into a desktop GUI. Reboot 3.) Launch LXTerminal and type in: sudo apt-get install git-core 4.) Typed: git clone https://github.com/gkaindl/ambi-tv.git
Pressed enter. 5.) cd ambi-tv/misc 6.) sudo bash get-kernel-source.sh 7.) cd usbtv-driver 8.) make 9.) sudo mkdir /lib/modules/3.6.11+/extra 10.) sudo cp usbtv.ko /lib/modules/3.6.11+/extra/ 11.) sudo depmod 3.6.11+ 12.) sudo modprobe videobuf2_core 13.) sudo modprobe videobuf2_vmalloc 14.) sudo modprobe usbtv

As soon as I press enter after typing in sudo modprobe usbtv, the raspberry pi freezes completely and does not respond- I even let it sit over night to see if it would free up, not no luck.

I am determined to have ambi-tv as I have been obsessed with ambilight since Phillips debuted it. I am to the point where I will pay someone to code the card properly and give step by step instructions on how to enter in LED light numbers. If not, I am willing to pay to have someone teach me how to do this.

I am in desperate need and have neither the knowhow nor the resources around me to address the problem locally.

My LEDs will be here tomorrow. I am trying the Hyperion method first. My only question now is should I leave my rpi on all the time or power it off when the tv turns off. I hope not shutting down the pi gracefully won't corrupt the sd card. We will see

I'm a little late to this thread but have you checked this out?

https://github.com/gkaindl/ambi-tv/issues/7#issuecomment-25052979

[nickmazz]

So I have everything up an running, but of course I have ran into problems. Check out the pictures and let me know what you think. The colors are off and they do not seem to be following the edge correctly. What do you think the problem is?

[nickmazz]

PLEASE SEE ABOVE COMMENT thanks

[nickmazz]

I do not know. I'm hoping Angora can shed some light on this.

[jcf6288]

I figured out my color issue. Are you using Hyperion or Ambi-TV

ambi-tv. what are you using? If you are using Hyperion how did you install it? I tried but with no luck so far.

[jcf6288]

I just followed the instructions on http://bite-in.com/. I used win32diskimager to load my sd card, then just followed the rest of the instructions. Problem now is my video capture card didn't work so I ordered another that should be based on the stk1160 to finish the project. What issues are you having using hyperion. I might be able to guide you through. The android app also works with the install.

Hyperion is easy to install, easy to use and i can recommend it (like i did earlier ;)). If you got questions reagarding hyperion, i hopefully can also help you.

Back to your problem: I think you can avoid it by changing one file with: sudo nano ~/ambi-tv-master/src/components/lpd8806-spidev-sink.c Now press CTRL+W and insert acc[3 * ii + 2](that will search that line for you). You should have found following lines in the editor: acc[3 * ii] = r; acc[3 * ii + 1] = g; acc[3 * ii + 2] = b; Which you need to edit. So if blue = red it would look like: acc[3 * ii] = b; acc[3 * ii + 1] = g; acc[3 * ii + 2] = r; I hope this clearifies the progress. If not, just ask me again. I hope this helps and does it, if not we need to think a little more about this ;)

Unfortunately I don't think that is the problem. I put up a test pattern, and the colors incorrect in all spots, and the LEDS keep flickering different colors instead of staying solid with the test pattern. Could it be possible that I haven't written support for the WS LEDs in? Because running the mood light doesn't do anything.

[nickmazz]

In addition to my previous comment, I am also trying to get Hyperion running.

on the bit-in.com blog- What is he referring to exactly? (ignore the error at the end of the script “install_hyperion.sh”. It is upstart script related and we will not use it anyway.)

Where in sudo nano /etc/rc.local do I add the scripts?

How do I open and run the Hyperion Config file? t

Then Finally how do I copy it over? I can't use WinSCP because I am running a Mac

[Angora]

One reason that the LEDs keep flickering might be that they don't get the 5V signal they need due to specifications. You could solder a little board that will output the needed 5V (there are some pictures and schematics). I cannot tell if that will be the solution for that problem. Another thing could be that you need to connect the ground of the LEDs and the RPi, if you didn't do that already.

If you go through the install routine it will throw an error at the end, that is to be ignored ;) Just follow the instructions and you are fine.

When you open rc.local there will be an "exit 0" at the end of the document. The lines have to be BEFORE that "exit 0".

You can try flashfxp or some similar ftp program.

Good luck ;)

My LEDs are 12v. I thought they were 5 when I ordered then, but they are 12v ( I Have a separate power adapter for them). What would I need to keep it from flickering? And in regards to Hyperion- I would love if someone can make a step-by-step for a noob like me.

SMI-2021CBE Somagic devices do not work in ARM Env. They can be used in Ubuntu x64 (i have managed to work with them, but they use more CPU power than 1160 one). On my blog you have a link to stk1160 one device, so use that one if you want to get stk1160 for sure.

[jcf6288]

What does adjusting the width and height and fps do?

[Phil1988]

your comments look really ugly with all that stuff and your emailadress :-) green screen = not enought ampere for the grabber... need a better power supply and a additional line to the grabber because the Pi couldnt support anough power to its USB port

[jcf6288]

Ok so I hooked up a rca source and it is just showing a green block. I disconnect it and see bars from white to black. Has anybody seen this? It isn't the power supply. I have a 5v 10a supplying just the RPI. I disconnected my LEDs so no draw from that.

[nickmazz]

Anybody got an idea for my problem? What diagram are we talking about? Will it work with my 12v strip?

Sorry, based on what you have said, the clock and data signal should come from you RPI and your power for your leds will need to be a separate 12v source. What was the link for where you bought you leds?

[jcf6288]

Make sure that all of your ground wires are connected, this should prevent the flickering.

[Angora]

That 12V power source would be an idea. Go for that for the first try. (and dont forget to connect the grounds ;) ) The schamatics i was talking about are: https://github.com/tvdzwan/hyperion/wiki/hardware (the second picture i think) It is in the thread for hyperion, but its the same for ambi-tv.

Does the signal have to be PAL or NTSC? I am using NTSC will this work or do I have to do something different?

The hdmi2av converter should make everything PAL

Does it have to be PAL. I don't need it for my setup unless it has to be a pal signal.

[nickmazz]

Check out this video, and read description please. Comment back on here if u can please. I'm about to try to find someone to hire in Columbus OH to get this working if I can't resolve it myself soon. http://youtu.be/cN_7rbgdcSI

[nickmazz]

So I might have found the problem. The link to the LEDS I purchased is http://www.amazon.com/length-individually-addressable-SMD5050-Non-Waterproof/dp/B00C3ZR90O/ref=sr_1_4?ie=UTF8&qid=1386186240&sr=8-4&keywords=WS2801+strip#productDetails

The LED strip I received is 12V and not 5V like it said it was. Could this be the problem?

[jcf6288]

They say 5volts that's weird. Could you take a close up picture of the strip, near where you can cut it, and where the solder point are. I am curious of what the connectors say on them.

[nickmazz]

Yeah here's two pictures.

[Phil1988]

Simple check for needed voltage is to count the leds between every cutting piont.

If the stripe is cuttable after every LED then its 5V

If the stripe is cuttable after 3 LEDs then its 12V

[nickmazz]

Yep every 3. I need 5v don't I?

No you need 12V. Another question for anyone that can help. For the Hyperion install, how do you configure it so that if a portion of the screen is black, the leds are off not just dimmed?

[nickmazz]

The diagrams I've seen use a 5v strip. Do you use a 12V Angora?

[Angora]

I got also a 5V LED stripe. The problem we have here now is, that the RPi is having 3.3V on the GPIOs and with that it probably cannot trigger the colors of your stripe. Two possibilities:

1. Buy a new one (easiest but probably most expensive way)
2. Try to solder an amplifier to amplify the 3.3V to a 12V signal. That would mean a little work, a little know how and some guy to help us...

Quick question, will the ambi-tv or Hyperion project be able to capture a widescreen image? When I hook up my Pi to the tv while everything is up and running, the picture is cropped. Is this due to the usb grabber? Is there a way to capture a 16X9 screen?

[nickmazz]

I'm not sure what your problem is really. When you look at the ambi-tv youtube video, he demonstrates it being used with a widescreen image (with black bars on top and bottom) and it still worked perfectly.

[nickmazz]

So my replacement strip came in. I plugged it in and....nothing. The LEDs are not lighting up. All I can get is the first LED to light up- so I think I was sent a faulty LED strip. What do you think? So I just said screw it and ordered another set of strips: http://www.amazon.com/Addressable-Waterproof-Connectors-Included-Attached/dp/B008KEO540/ref=sr_1_6?ie=UTF8&qid=1389707855&sr=8-6&keywords=WS2801+5v

Do you have a power supply you would recommend that I can hook right up to this without any cutting or soldering? Im pretty fed up at this point lol.

Angora- what do you think? Also, is it easier to do Hyperion than it is Ambi-tv? If so, I'd be happy do donate to your paypal or something to make a step by step for dummies.

[Angora]

It's normal that only one LED will light up, when there is no signal on the strip (at least for me, no gurantee on that though). Try to check your layout again.

Good to know....I'm going to re-install everything and give it another shot and let you know. This is what I am using for my power supply for the LEDs...do you think that this should be suffice? Input is 9 volts, output is 5 volts.

[Angora]

If it does, what it is supposed to do i would say it's suffice. I just checked and it's totally normal, that the first led lights up ;) So there should rather be a problem with you build.

Got it all working. Thanks to those that helped. Angora, I was able to get your initial first image working properly and adjusted . I do however have some green flicking. I have some on the top and left side.

[ghgoldberg]

I have completed a ambilight hardware build based on gkaindl's setup. I am in the process configuring the software, and this thread has been of great help. I am posting some pictures of my hardware setup, maybe it will be of use to someone. I can provide details of the chassis, connectors, etc. if anyone would like it.

The Mean well RS-75-5 5V power supply is capable of outputting 12 amps. It is used to power the entire system. The AC input is filtered using a Corcom 2EDL1SC power entry filter (which has an integral socket, switch and filter).

No doubt, I'll be back with questions while trying to get the software to run.

[supercrab]

@ghgoldberg Thanks for the hardware tips and you picture uploads! Very helpful :+1:

I have all my bits but have yet to put it altogether. I'm probably scared of it all going bang!

[ghgoldberg]

@supercrab - Glad the pics help. There was a huge amount of trial and error to get to the final layout. The chassis that I used has a 17" x 10" footprint. The RPi and the power supply are the only components that are fastened to the chassis by screws. The HDMI splitter, HDMI2AV converter, and the USB hub are stuck on with Sekisui #5760 thermal adhesive tape. And it is very important to use ultraflexable cables everywhere. I can give you specifics for the cables and connectors if you would like.

[supercrab]

@ghgoldberg

I was wondering what would be the best way to make the system neat and tidy and your solution is perfect! You've got a 4 pin din for the LEDS, HDMI in, out, Rasp PI HDMI out, 2 USB, and a network port. I've done a quick search on eBay and can find all these little the chasis connections. I was just wondering how important is the AC filter? I'd be interested in where you got the cables and connectors from :)

I'm working on a web controllable version of AmbiTV so it's important to have that network port! ;)

[ghgoldberg]

Here is where I got much of the hardware:

on eBay: 4 conductor shielded audio cable ($7.50 for 10 feet) Corcom 2EDL1SC Snap-in Power Entry Filter (2A @250V) $10.00 Flat Ethernet Patch Cable, 1-ft $3.41

from parts-express.com super-slim high-speed HDMI cable, 1-ft part# 180-686 4x$3.87

from mouser.com Hammond 1441-30BK3 Satin Black Chassis (17" x 10" x 2") $30.00 Hammond 1431-30BK3 Satin Black Bottom Plate $13.60 Neutrik MFD fixing plate (6x$0.56) none needed for RJ45 connector

from usbargainsound.com Neutrik NAHDMI-W-B HDMI 1.3 Feed-Thru Adaptor 3x$17.95 Neutrik NAUSB-W-B Panel mount reversible USB Type A&B Black 2x$8.55 Neutrik NC4FD-L-B-1 4-Pin Female XLR Chassis Panel Mount with gold contacts $5.95 Neutrik NC4MXX-B XLR 4-Pin Male Cable connector black housing with gold contacts $4.95 Neutrik NE8FDP-B Ethercon (Cat 5e) RJ45 Feedthru Chassis Panel Mount Jack $15.95

To make holes for connectors: mcmaster.com 15/16" high-speed-steel hole saw (McMaster-Carr #4146A17 $23.86) plus 3/8" hex-shank arbor (McMaster-Carr #4146A92 $6.82)

I highly recommend using the power line filter. It will beat down any noise generated from the switching power supply from contaminating any of your other AV equipment. Also, it will provide protection for your RPi and other ambilight processor electronics from noise on your mains. Also, note the shielding on the lines from the RPi to the LEDs.
