Re: Running Personally written Programs on Rasp. Pi

If i were to build a quadcopter and write my own program for it. Would i install raspbian and just run my program through the operating system or do i, somehow, install my .py files directly onto a microSD card and put it into the rasp. pi? You'd want to use something that was real time and not Lin...

Re: Which version of Pi for web browsing

If you are including pages running tons of scripts, and things like Youtube then you are going to want either a Raspberry Pi 2B or Raspberry 3B . Most stuff on youtube can be downloaded with youtube-dl and using that with omxplayer really cuts the load although running firefox on any original pi ev...

Re: Which version of Pi for web browsing

Is there enough of a spec difference between all of the Pi's available that I should choose one over another for just the purposes of web browsing? If you want to run firefox, you'll want as much ram as possible. The originals and the zeros are only a half gig, the one gig models are better. Obviou...

Re: Headless setup: no keyboard, display or frustration

With my pi hooked up to my tv, I checked its IP address by using the command sudo ifconfig, and I double checked that I was entering the correct address. I also used ping and I got a good connection. You should try -v -vv -vvv with ssh to see what sort of errors you are seeing. Before you try to re...

It often doesn't do all the dependencies and that is the case when trying to install X on R. jessie lite using what one might think are reasonable install strings.

Re: One large 5 volt supply?

If, for example, you connect 10 PiZero to a 5V@20A PSU, a fault such as a short circuit in a connected USB device may well cause a fire due to severely overloaded cables and PCB tracks. Clearly using the correct 5V@2.5A PSU protects against this under such fault conditions. What you are counting on...

How do you know that it's not a cheaply made PSU? Surely there's more to it than just you paying a lot for it.

Ehternet switches come in 5-port, 8-port, 16-port and up sizes. No such animal (that I've ever seen) as a 4-port switch. Only four ports are very common when the switch is integrated into the cable or dsl modem. This makes for real fun when one is repurposing the device as just the switch part and ...
