Free Magpi Magazine for Raspberry Pi aficionados

I discovered that you can down-load all the back-issues of MagPi, the official RaspberryPi magazine for free from their web-site here:

https://www.raspberrypi.org/magpi/

Lots of pretty pickies for light reading. It's aimed at education from beginner level but there are a lot of ideas and handy code in there relating to all permutations of pi from the beginning. 

I've found some useful info and ideas in there. 

Cheers. 


Handy little app for Pi afficionados.

I have found this little app from Adafruit to be really handy when I want to ssh into a Raspberry Pi but can't remember the I.P.  Works on most OSs.

This can be annoying when you have a bunch of them as a few of us do. 

Just click on 'Find my Pi' and it will come up with the I.P. for the near-by Pi.  

Use ethernet if it doesn't already have wifi up. 


Pi-Arduino Integration question

Humanoid's picture

On the subject of Raspberry Pis - for whoever knows about this:

I use two Megas to run my inMoov with MRL and (generally) Windows.  I am adding some wheels to the base and am considering throwing one of my pi family in there just to run the wheels, rather than use an Arduino Nano or similar.  I might even put a pi-zero in the head for some duties. 

BUT- it now occurs to me that, even though we have a Raspberry Pi service in MRL, the pi is a computer not a micro-controller. 


Desperately seeking ideas re: large build-area, cheapish 2nd 3D printer

It's come to my attention that my excellent Flashforge is not cutting it in the legs department. The build area is just too small for legs and other larger projects I'm contemplating. 

I don't want to spend mega-bucks on a second printer at this stage.  

Can anyone please suggest/warn about any 3D printers they've used with large build areas? I would like a fairly reliable one with a build area around 280mm/300mm cubed or larger. Preferably with a heated build plate. One extruder is okay.


Why this bot no worky? (Been away again)

I have tried to run this chatbot on Windows with Chrome (no inMoov connected). I duplicated the Alice2 bot file and called it "ghostchat". When run this in MRL it opened webgui but threw an error. I modified nothing in the swinggui. Should I have? Everything looks different in there to what it used to when I last used it.


Advice appreciated with a couple of issues - Windows and Mac OSX

I would appreciate anyone's thoughts on these issues:

I'm using a USB Hub which is working okay. The same one Gael recommended. 


My 3D printed omni-directional mechanum wheels for Ghost the inMoov

I've made 4 of these, from ABS, with the Flashforge 3D printer and hope to make them work on my inmoov, 'Ghost'.  


Some advice required for getting a script running on a newer MRL build please!

Hi all, 

This used to work fine under the earlier builds. I can't get it to work in build 1723 which I'm told is worky.
