Re: Using same SD card in Pi Zero and Pi model A or B?

OK, that is sounding better, so this is not much of a concern since my new projects will not be based on RetroPie.

so I can use my existing Pi3, using Raspbian, to get the software side working for my Pi0 projects.

Thanks everyone.

Re: Using same SD card in Pi Zero and Pi model A or B?

I know that the SD card is not compatible between the Pi Zero and the Pi2/3 ... Eh? Where did you get that idea, that's 100% wrong. If you build a NOOBS 2.1 or Raspbian Jessie 2017-01-11 micro SDcard that will boot on ANY raspberry. It only needs a physical needs an adapter for RPi1A or RPi1B machi...

Using same SD card in Pi Zero and Pi model A or B?

I know that the SD card is not compatible between the Pi Zero and the Pi2/3, but what about older model A/B or any other Pi model I can get? I have a number of pending projects for the Pi Zero, so I was hoping to use another Pi model as the development environment due to ease of interconnects, and w...

Re: /etc/rc.local not running at boot?

On a side note, a colleague had a similar issue with rc.local during boot and found odd permission value for the file. He changed it to 755 and it starting working.

not that other settings wouldn't work, but that is the setting he used.

Re: Mausberry Circuit Script Slowndown

No, it replaces the original switch.sh

The new script uses less CPU, so it must have 'fixed' the issue the OP was having.

This was a very old thread, and you can see that there hasn't been any follow up on it in years.

Re: Mausberry Circuit Script Slowndown

I'm really interested in what you've done here but I'm a little bit confused. You're using python instead of the switch.sh script? How do I go from using the switch.sh script to what you've written? You do not install the switch.sh, or remove it if you already have it installed. You save the new Py...

Re: Pi Zero with 0 or 3 USB ports?

So a RPi Zero with a $0.50 plastic (production cost) casing, a $20 LCD, and about $15 worth of misc stuff for over $100, sounds like a good deal (for the producer, not the customer). This is the main trouble I have with watching Shark Tank - they always tell the manufacturing costs, so you see the ...

I had one of those and returned it since I could not get it working on my Zero.

I got one of these and it is working very good:

I've ordered three Zero from Adafruit. Each was $5 shipping to California. This morning Microcenter seems to have changed their website and they no longer list the Pi Zero as an individual item. Before they use to list it as "in store purchase only", but at least you can check stock of them. Even th...

Re: Pi Zero dropped at Adafruit?

Maybe, but when the Pi3 came out, they didn't have a listing for it right away... Does that mean there will be a blow out sale for the old Pi Zero? :lol: For my project, the Pi Zero fits perfectly, so hopefully a new version doesn't change the size (or hopefully its smaller). This is why I am intere...
