Re: Showing a Pi can replace a standard computer

Agreed. But for my purpose, it will never fully replace traditional PCs (due to lack of RAM, hard drive size, etc.). However, if I can open people's eyes to see what can be done, then I've accomplished what I've set out to do.

Showing a Pi can replace a standard computer

I have the opportunity to show a group of people that a Raspberry Pi (Model 3B) can easily replace a full laptop or desktop in terms of general performance. The people I plan to show generally believe that Windows 7 is the preferred option, and usually on a full desktop computer. When I demo it, the...

Removing Thonny for Python IDE

I have been asked to remove the Thonny Python IDE on a Pi image that I maintain. They would prefer to use the basic Python IDE. Is there an easy way to make this change?

These are excellent suggestions. Thanks for the help, and it is good to know this isn't a wide-open device. I wasn't aware that Linux was more secure by default.

I believe my Pi was hacked and now I want to verify it.

I have a Pi set up as a weather station receiver, feeding data to the internet. Every week or two, running completely unprotected, the Pi fails in various ways (freezes, Wi-Fi fails, fails to boot, etc.). I usually re-image the SD card and start it running again. This time, I notice unusual behavior...

Re: I can now monitor power consumption of my solar powered

As an update, I modified my python code so that it tries to upload the data to Cosm.com but if it fails, it just ignores it, waits 30 seconds and tries again. This seems to be better performing. So for anyone uploading to Cosm (which I highly recommend), remember to use a "try" statement in your code.

I can now monitor power consumption of my solar powered Pi.

A while back, I posted that I had connected my Pi to a large solar panel and Lithium battery so I could run it 24/7/365. Recently, using some parts purchased from Adafruit, I added a current sensor so I could monitor if the battery was charging or discharging. This was my first experiment with the G...

Re: Shutdown command after a period of inactivity?

I need to halt the processor to power off the Pi so I don't risk corrupting the SD card. I realize the Pi takes very little power (2 watts at idle), but this will be on the same power strip as the printer, so when the power strip power shuts down, the Pi needs to have been halted. The bottom line is...
