I don't use the pi gui, all my pi's are "headless". You need to have the X-system INSTALLED on the pi, but you can still keep it booting up to the commandline as set in raspi-config. The X-system sends the screen info to your local machine (known in X as the "server" which does seem the wrong way ro...
As long as you have x installed on the local system (actually on both systems), you can do this. Run the pi as a command line only system. Set it up to do this with raspi-config. Then from your remote system call it in ssh by par example:- ssh -l pi -Y c.local or ssh -Y c.local if the login name is ...
To update my previous post, I have continued working with Go. Currently using mangos v2 which is a fully go implementation of nanomsg (a later version similar to zeromq) as described in mangolink.. My stuff is on github :- https://github.com/richrarobi?tab=repositories Particular things relevant to ...
So then the question is, which language is the easiest to use to create such programs? I just added an example Python in my mangolink post on github. It shows Python calling the reply server (mangorep.go) and receiving a response. Now (call me Barmy?), I can run my reply code on any system Linux Mi...
After trying Rust, and finding it too "tight", I went back to golang. While I admit I am still learning, I find it fits my way of working. The authors have done a lot of work to make the programmer's life easier. Also I find it is "fast enough" and appears much faster than Python (not a challenge) S...
Ugh! Sorry! Try Golang? (But you have to find the language that suits you) I doon't like Java, tried Scala, it is too "sophisticated", I tried Rust (too "tight"), etc. (Just my personal view - some like more "obfuscation" - some (me) like it simple, etc) There is a pre-built version of the latest go...
I haven't posted for a while.... and at the risk of starting a messaging war, I am still using zeromq http://zeromq.org/ - while looking for alternatives to Python, (etc). I have been writing some code in go(lang) - tried Rust (it didn't suit me (or the other way round)) - I found golang fitted my e...
This has been rumbling on ever since the sense hat first appeared. I have tried all sorts. including a "black-hat hacker". Currently, I have the hat mounted by use of a few bits of "fake" meccano on some stand offs. The hat is NEXT to the pi(2), and at a slight sloping angle for visibility, and ROTA...
Octapi utilizes Dispy and Pycos python software, both available on Linux Mint and probably on "other" systems. Within Pycos is a package called netpycos that offers distributed tasks across a network. Now while clusters look like enormous fun, they don't really provide real power using miniscule com...
I use mpg123 to play internet radio. eg:= mpg123 -@ http://adsi-e-02-boh.sharp-stream.com/jazzfmmobile.mp3 mpg123 also on jessie.....

Firstly Don't quote me on this - I am not the expert you need....However, I believe the Arduino would be better for the real-time part of your project, then you could link it via serial or USB to a computer (pi or other) to record/analyze the results at less than real-time speed.....
I was lucky enough to pick a pack up on Friday. The pack came with a set of 40 pins, unsoldered . I have been wondering which pins I am likely to need as I don't think the mag made it clear. I found a link that includes a circuit plan https://aiyprojects.withgoogle.com/voice/#makers-guide-4-1--conne...
I have to agree with Heater ( :oops: ) - I use Linux Mint XFCE on my Laptop and Desktop PC's, SSH into my Pi's with options as follows: ssh -Y -l pi a.local Note the upercase Y . then run pcmanfm with & at the end to keep your terminal session available, You can run most apps from the pcmanfm GUI th...
I have a Logitech K380 which I bought recently (compact to fit in a carry-on) - so far it looks very good. It has three buttons that let you select which of three systems you connect to. Also it supports Linux and Android (probably those other OS's too?!) - You can switch between the systems in a si...
Use plastic beads as spacers? wilco or yorkshire trading sell them cheap in bags. Various mounts for sale - various dubious designs - some better than others. The smartipi lego camera case so far is the best I tried, nearly perfect. One other case bent the camera pcb so much the camera "eye" popped ...
Carbon offsets are complete tosh aren't they? Unless you're planning to fill the empty oil well with carbon it's just a con. It is all a load of "politically (in)correct mumbo-jumbo" (am I allowed to say "mumbo-jumbo"?) - I might know a local council (maybe Bracknell) where (I am told) residents ha...
You might have to write your own? I was searching for gucview (via a search for webcam control on Linux) so found your post... If you do, the only python interfaces for webcams I have found so far are in pygame and opencv. There are some examples of pygame and cameras posted elsewhere. The one in py...
Thanks for the reply, still can't get my head round the logic of it ! I managed to get what I want.... did the partial letter box thing as normal now, camera.resolution = (1920, 1080), and resized to (640,360). Then, did camera.rotate=270. This gives a zoomed letterbox image on its side in the web p...
I wanted to use a 16:9 image zoomed in as per this http://picamera.readthedocs.io/en/release-1.12/fov.html using 1920x1080 (resized for conveience to 640x360. OK - nice enlarged effect.... Then I decided I wanted to take the shot vertically. Turn the camera on its side? Nope! It knows somehow.....it...
