Thanks for the replies. Always useful to get some feedback as it meant I could do some more focused Googling. I managed to solve the issue. script1.py - Flask app launched on boot and running under NGINX/uwsgi. Runs as user "www-data". script2.py - Script run by user Pi. It creates new directories i...
Hello, I've got a Linux permission issue. It's causing me more hassle than anything else in my project but it a relatively minor feature. I've got two scripts. One runs as the "pi" user. The other is a Flask app running under a NGINX/uwsgi setup. It runs as "www-data". The first script creates a dir...
Unfortunately those sort of sites don't bother to update tutorials when things change. That article was written in 2015 and I bet they haven't made any changes to it. Try a Pi dedicated site rather than a pile-em-high-and-forget-tech-site : Enable I2C on the Raspberry Pi Enable SPI on the Raspberry ...
It's a poor attempt at trolling. When the competition can't even troll properly you have to wonder how good they are at electronic design and engineering.
Since the update I've struggled to get the Forum search to work. Certain searches always result in a "we are currently experiencing high traffic" page. For example : https://www.raspberrypi.org/forums/search.php?keywords=energenie It does this on multiple machines from different internet connections...
I'd be interested in knowing if there is an answer to this. I suspect a new version of Minecraft for Pi would need to be released. I hope Microsoft let their Minecraft team release an updated version at some point.
There have probably been 15+ Raspbian releases and 10+ Pi hardware variants. Tutorials will be valid for a number of those ... but when you write a tutorial it's impossible to test on more than a few of them. It's also impossible to re-test every time a new Raspbian is released or a new Pi device is...
The community is stronger than ever so don't worry about that. The Foundation will update their tutorials if you let them know when their is a problem. Because the Pi has been around for almost 5 years there is a massive collection of articles, tutorials, guides and information. Unfortunately change...
Changes to avconv (and ffmpeg) can sometimes break previously working commands. So the guide says : avconv -r 10 -qscale 2 -i animation/frame%03d.jpg animation.mp4 but throws the error about qscale. This seems to work on my laptop: avconv -r 10 -i animation/frame%03d.jpg -qscale 2 animation.mp4 The ...
The GPIO are fragile but if they weren't the Pi would be much bigger. If they were happy switching bigger loads they wouldn't suit most people. I can't think of any board that switches high-current loads out-the-box without some external components. What LED do you want to switch? The current involv...
This is an old thread but for the benefit of Google visitors I'll add this .. MotionEyeOS supports all the Pi models but you my need a specific image for that model. Here is a list of supported boards with a link to the image file you need : MotionEyeOS Supported Hardware Boards It's so easy to setu...
How many LEDs are you going to use? This would be good to decide early on because it will determine what options you've got to drive them. My mum had an extensive 12th scale dolls house collection. I inherited her "Witches House" and unfortunately I didn't have room for the others! I made and sold a...
Should be fixed now on the blog post. There is a strange bug in the syntax highlighter I'm using where it refuses to place a line break between those two lines. I've put a comment at the end and that seems to fix it.
Have you tried different batteries? I had loads of problems with my DS1307. Some of which I think might have been down to the quality of the battery holder. I wrote a tutorial on it which I had to abandon because the devices were so unreliable. In the end I went for a DS3231 and instantly made more ...
Did you use the Wifi configuration utility within Raspbian to set the Wifi password? If not try this WiFi configuration tutorial . I had real trouble with my RTC module (a DS1307). In the end I went for a DS3231 and that was much easier. You are best looking for a Raspberry Pi specific tutorial wher...
You need to start with the basics to check the camera is working before you try streaming. You need to try the raspistill utility on the command line to take a single photo. i.e. raspistill -o myimage.jpg See http://www.raspberrypi-spy.co.uk/2013/05/taking-hi-res-photos-with-the-pi-camera-module/ fo...
Consider switching the Pi for a Model A+. It will be smaller and use less power and you only need 1 USB port for the dongle. It might mean you can go for a smaller battery.
I've used a number of Power banks with the Raspberry Pi. It really depends on the the total capacity and the weight you are after. I quite like the RAVPower RP-PB13 14000mAh, Lumsing PBJ-6200 6200mAh or Lumsing LUM-008-001 10400mAh "Harmonica”. I've got blog posts on them all in my Power section . I...
