Re: A portable maker space for home

Nice. I had a similar problem, plus I was always taking my stuff from one place to another (work, home, project locations, etc). I built a station into a steel case that everyone warns me to never take to an airport... It has worked very well, and I have a smallish 4-tray parts organizer cube thing ...

Re: Raspberry pi camera streaming

I am not familiar with gstreamer, but if you have streaming or camera preview up and running on the local/hosting rpi, I have used realVNC to remotely view the screen. It used to be a beta option you had to enable to be able to watch streaming video preview stuff. Not sure if it's still beta or just...

Yes, having the same problem with a fresh install of the latest raspbian just this week. I'm tryna do my homework here and it keeps just closing and losing my work every 30 seconds to 10 minutes. I don't suppose you've found a solution?

Re: Beginner looking for where to start with robotics

Learn to use your gpio. First, just blink and LED - plenty of tutorials for that. Then learn how to use the same script to turn a motor on and of via a relay - most any DC motor will do. Then learn to make the motor start, stop, and reverse. (Reverse with a 2nd relay) Then learn to vary the speed of...

Git (GitLab) Noobie questions

1. How have I not discovered this earlier?? This is so much better than my messy, uncommented DropBox folders! 2. Can I upload the executables, and revert the program that is running on my Pi to any version as simply as commanding a revert? Or do I have to download the code for whatever version I wa...

Re: Pi3 Suddenly won't compile even a HelloWorld... Illegal instruction/Segmentation Fault

Gcc at least started to work from command line. It gave me errors about "cout<< " which I think I recall hearing that it's not a thing in c, so maybe makes sense.

Re: USB to USB/ Windows to Raspi w C++ serial ...what cable?

Hmmmm... I guess my experience of serial communcation is over either the gpio uart or usb via an FTDI chip, so it's always been as easy as a line of code like serPutChar( ttyUSB0, 'x'); I don't know how to do the same with IP. It sounds like something I should learn though - will start googling, but...

Mostly because I'd have to learn new tricks as far as making sure the wifi adapters always have the same name for my programs to reference.

Soo.I want to write a pair of C++ programs that would require the machines to talk back and forth with the wiringpi or pigpio library.

I use a USE FTDI device to communicate with my roomba and my own c++ programs. I am considering adding another USB FTDI device to talk to an Arduino... my entire program just relies on USB0 being my roomba. Will a 2nd become USB1 and how does the pi/my program know to keep them in that order boot af...
