Re: Sense Hat % Humididty reads erroneously high?

Can that sensor be contaminated by residue buildup / condensation etc? Would cleaning / applying isopropyl alcohol damage it?

Re: wildlife cam help

Motion Eye OS will not even boot up without an Ethernet connection. With the stock install it looks for an ethernet connection and will just endlessly reboot until it finds one. Once it has one you can log in and setup a WIFI connection if you want, and change any of the other settings. I don't know...

Re: Only one USB port?

Yes its an easy install manager. It sets up and installs differently than just plain Raspbian though. There is extra bits installed. Extra steps the first time its run also I believe.

Re: Only one USB port?

Raspbian should boot up even with no monitor connected. You could try that cable and monitor on another device to rule it out as being an issue. I have no experience with NOOBS though, maybe its waiting for keyboard input or something? Any reason you went with NOOBS instead of Raspbian?

Re: Apt upgrade and dpkg --configure -a stuck

Did you run

Code: Select all

 sudo dpkg --configure -a   
?
I got a similar error message after upgrading my AIY install, IO error or something.
Next time I tried to apt-get upgrade I got the message to run sudo dpkg --configure -a. I did and all was fine after that.

I believe all but the Pi Zero have a poly fuse that will limit the current available to peripherals.

Re: Will people please think about low res displays?

I will concede the PiTFT was a poor example. It was what came to mind at the time.
I've had windows open with the OK off screen on my Official Pi foundation screen though. I then have to right click and select "move" to get at the button I want to click.

Re: Power adapter with 5v 4amp pi3 B+

What he said. I have one Pi running off of a 5V 10A power supply and another running off of a 5V 4A power supply. They only draw what current they need.
Being able to supply more than what is needed is not an issue.

So you have a 12V to 5V adapter feeding 5V to the Powerboost input, correct? There is an Enable pin / connection on the Powerboost that will turn it off. The upconverter will be off and the 5v out will turn off. The battery charger will still run though if 5V is still feeding the powerboost. You don...

It can be frustrating, it can also be a lot of fun and very rewarding when you get your project working the way "you" want it to.

Re: RemotePi board & polyfuse - sorry, I don't understand that, please explain

They use a poly fuse because in most cases, if you give it enough time, it will recover from a current overload. If you do manage to exceed its current rating it overheats and basically becomes a high impedance. That restricts your current flow to almost nothing. Let it cool off over night and it re...
