for a script that requires keyboard input / display we have a slightly different service setup , let us say that we want to output info and receive keyboard control on a terminal say tty9 [alt-f9] using the same procedure as https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=7192&p=828947#p828...
That looks like a cool way of controlling the temperature of the rig, I will have to definitely look into doing that because it looks like a interesting way of controlling the temperature. Could you please send me a but more information of how you did that? Thank you You have probably noticed that ...
Thank you, I am currently looking at the website now. I cant seem to find out how many fans the Raspberry Pi can support, I am looking at running 10 fans for my build, the main reason for this large amount fans is that they will be placed all around a the desk. What do you mean by make the fans set...
Hello everyone! so I am working with a Digital Potentiometer using this website's code http://electronics.stackexchange.com/questions/94479/digital-potentiometer-mcp4131-with-raspberry-pi and it all works I just need help understanding and altering the code.[/code] I've added some comments for you....
If the polyfuse protected the pi then it would have reset after a few days, otherwise you could replace all the power supply components and still have no guarantee of the pi working afterwards.
I was thinking of using Adafruit NeoPixel Digital RGB LED Weatherproof Strip 60 LED. If this is not a viable option for a LED strip please could you link me one that is as I am not to sure on which ones are suitable for my build. I have looked at both the links you have sent me and I believe I have...
!!! They all are the same! They may all look the same but there are important differences between them. go to amazon and sign in. Go to "your account". Select "your orders". Find the lcd display that you bought in your order history. Click on it and copy the link to the item. Post the link so that ...
I have an RPi B+ not anymore booting after I did an update. I know it is the pi because I already replaced with working sd card and working power supplies. When turned on, the red and green LEDs turned on forever as if there is no bootable sd detected. So far, this is the only post in google that m...
This has been observed elsewhere as well. The stripes were replicable by following the same process. My setup is I'm powering the touchscreen display board (v1.1 with official power supply) and then powering the rpi 3 from that using the jumper wires. If you shutdown the pi and unplug it the screen ...
Just curious, I have the parts on order, but... Why would it work for about 4 continuous hours and then not again if that was the issue? Wouldn't it be more likely that it would work a bit and you'd wouldn't see such a consistent error? Also, why are they so steady with Arduino vs RPi? Arduino has ...
I know this seems a bit of a loopy question, but I'm looking for a way to test touch capabilities of a BrightSign presentation on a touch screen. Is this even possible :?: The 2 touch screens I have currently are a Toshiba Satellite touch screen lap top and a 7" Raspberry Pi touch screen. It doesn'...
If your using a pi2 then i expect the image is pretty old, maybe you will need to do a: apt-get dist-upgrade to get the latest version. I recently had the same issue with my daughters pi and i was glad i had taken backups of various files first as she lost her minecraft world during the dist-upgrade.
I reconsidered this, and have received 3.5" car backup cam display instead. Link: https://www.amazon.com/gp/product/B0045IIZKU/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 Now there is an issue. This display works off of 12 volts and I have a 3.7 volt battery. So I need to modify it to run off of US...
This means I have to "steal" a monitor and keyboard for a PC to get going. Not a big problem, but everything is a lot easier with this label. And it can not cost many cents. Magne prepare an SD card image for getting MAC address from pi: 2+ hrs work Then add either: USB receipt printer ~£22.00 (per...
I was expecting to see a /dev/spidev0.0 as well as the /dev/spidev0.1 most of the websites that I have come across say that this " ls -l /dev/spi* " is a good test, and the results on the few webpages I was looking at show two lines, exactly as you have described. I'm not sure what the deal with it...
I'm fumbling my way ghrough here, hopefully we'll figure it out (or give better data for someone else to help further). I was expecting to see a /dev/spidev0.0 as well as the /dev/spidev0.1 please look in the boot config file and check for any references to spi. sudo nano /boot/config.txt We are loo...
I sure do have that directory and led.py tucked away within. All seems ok at a glance. http://i.imgur.com/rTne1Nj.jpg Buggered if I know why it is telling me it cannot find the file or directory! Ah, I re-read your original post the problem is within the file led.py: line 51: self._spi.open(spi_bus...
