Re: How many pi's do YOU own?

You can't buy more than "one at a time" from retailers, but as far I know you can own as many as you want. I can only ever add 1 Pi Zero "or" 1 Pi Zero W to an order. Any time I have tried to order one of each or two or more of one type, it was refused. I'm not complaining, I'm fine with that, it gi...

Re: How many pi's do YOU own?

I like to keep 1 or 2 on hand with no header soldered on, just in case I want to do something fancy. I have quit a few Pi Zero's with female headers and 90 degree headers on them. That lets me plug them into Pimoroni's Min Black Hat Hack3r or pHat Stack and ditch the hassle of using a ribbon cable.

What driver / software library did you install for it? it's a self contained code. you run it once, it give you the ID and the result. If you want to know a bit less, I can suggest looking at Adafruit or Pimoroni code. Here's a link for Pimoroni code, on the there a link to some example etc. https:...

And a button that can be used to do a proper shutdown, and boot up. It doesn't remove power to the P...

Re: Switch to turn on and off the P4

I do it via a dtoverlay, dtoverlay=gpio-shutdown . Momentarily grounding GPIO 3 will have Raspbian / Pi OS do a proper shutdown. And by default, grounding that pin again will have it boot back up. As long as you don't unplug the power supply. Enabling i2c will stop the shutdown from working via GPIO...

And they display the date and time, plus other info. Adding a RTC saves manually having to reset the date and tim...

Ok, when you said "same problem all the time on the one not working" I thought you meant the DS3231, but you meant the Pi. I'm pretty sure there is a second alternate i2c bus that can be enabled, I have never done it, and don't know how its done though?

There is no ARM Windows for the Raspberry Pi. Is it possible to install windows on a raspberry pi. Not on a Pi 4 no. You can install Windows 10 Internet of Things on a Pi 3B but Windows 10 IoT isn't your standard Windows. It's a very basic and IMHO limited interface. And I think you'll need some Vi...

It likely has a short to ground on one of the i2c pins. It's for sure a hardware issue. If you have soldered a header on it double check the soldering.

Thanks for that. Weird thing is, I have been using it for over a year now, plug + play without having to do anything extra? It works right out of the box in Stretch or Jessie. If that driver will get it working I'll happily install it though.

Re: Raspberry Pi 4 White/Red Case Sufficient

I also really like that case, from a looks perspective. It's a nice quality case. But, unless something has changed, IMHO, it's lacking in ventilation. There are no vent holes to let hot air out. The Pi 4 will not overheat, but if it does get overly hot it will throttle back to keep from overheating...

Re: No red LED Pi 4B

I would think that if the voltage was so low that the LED didn't turn on, that the Pi wouldn't even boot up? Maybe the LED got flipped around backwards some how, and its reverse biased? The red LED turns off when the voltage falls below 4.63V, IIRC. This is well outside the specified minimum of 4.7...
