Re: Syntax Error in Script

Hello, Python version is still 2.7 When you type python at the terminal, what do you get, 2.7.x? On arch, I get 3.6.0 On my pi3, I do get 2.7.9. If your program needs 2.7, trusting that just looking in the path for "python" is version 2.7 might be risky. Perhaps a shebang that asks for a specific a...

Re: videos in full screen stops and starts

I am trying to play videos from youtube on full screen using my raspberry pi 3, but the video continually stops and starts. I've tried everything, I'm sceptical you've tried everything. For example, if you download the video from youtube using youtube-dl, you can choose the resolution and format, a...

Re: Fair Pricing, opinions differ?

My other printers do have heated beds. In this design I wanted a good bootstrap point, an entry level 3D printer. The firmware and board do support the addition of a heated bed, that the user can source separately. If using PLA in a reasonable environment it is possible to do a lot more than you wo...

Re: Turn on and off your PC with a raspberrypi

You could probably run the Pi from 5V STBY off the ATX PSU and mount everything inside the PC case. You could use software on the PC to safely shutdown and use a 433MHz remote control mains socket to cut power and turn it on again. If the pi is going to control this and it is powered from the stand...

Re: Starting terminal on boot.

I think I may have have said that wrong. What I mean to say is that I need the LXTerminal to open upon startup. This is so a C program I have running at startup can output to it via Print statements. There will be no user input other than starting the pi. I have seen people do this for python based...

I understand that measuring voltages is not shorting it but I did mix up the terminals and I think that could have been the reason for the short. Any other thoughts? Mixing up the terminals doesn't matter on a digital meter. But if you shorted them or the pins by fumbling around, there's no resista...
