Re: Powering A Raspberry Pi 4

Get an adjustable boost converter capable of at least 5A output, and set the output to 5.1 or 5.2V, if you're stuck on using a single lipo cell. Buck converters are substantially more efficient than boost converters, and you could use 2 lipo cells half the capacity of the one you're using and end up...

Re: Pi Zero W for plug n' play TV device

You mentioned security. What are you looking to secure it against?

Nothing is perfectly secure, it's always a tradeoff, but reasonable steps can usually be taken against a specific threat.

Re: RPi 4B: Hotswap 5V pin power with USB-C power

In my experiments, even with isolated supplies, the Pi4 will reboot when you connect/disconnect the USB-C power, regardless of power being available on the 5V pins. Not sure why, it just does.

Re: Sharing a Linux PC’s internet connection through USB to Pi Zero

There's nothing different about it being a USB interface, just use the appropriate interface name (eg usb0 instead of eth0 or wlan0)

Usually your usb interface will be called "usb0" but you can list all available interfaces by running

Code: Select all

If you're able to SSH to it, you've already established a network connection through USB, so all you need to do is setup connection sharing using one of the many methods available, making sure you use the appropriate interface name for your USB network. https://help.ubuntu.com/community/Internet/Con...

Re: RD Client on iPad improperly connects to Xrdp on RPI 4b

Can you try using a different RDP client on the iPad to see if you can isolate the problem to the Pi?

Or the opposite, connect to a different RDP server with your current iPad client?

Most likely bumping into the 1.2A limit for USB power, this limit is combines across all USB ports.

Re: Which Pi board can i run Asphalt 8 on?

The problem is entirely software support. No Pi has native Android GPU drivers available, so Android will never run anywhere near the full potential of the hardware. I do not see these drivers forthcoming in the near future. Running Android software has never been a goal of the Pi foundation. The Ro...

Re: Is lineage the only Pi4 OS that will run Android apps?

The biggest stumbling block for Android on the Pi seems to be lack of proper drivers for the GPU and video decoder. Without at least a working GPU driver performance will never be very good, and gaming will remain basically a no go. Something like AnBox might give better results as it doesn't actual...

Another possible option for audio output is if your display/tv has an audio out (3.5mm or RCA) you can use HDMI audio to the display and analog audio out from that to your powered speaker, etc. It will in almost all cases sound better than the built in audio circuit, as well as using less CPU power....

I'd try another cable for sure. If there's a faulty connection somewhere the difference between working and not could literally be a few degrees of thermal expansion/contraction, or a tiny alteration in the way the cable bends. It takes seconds to swap a cable, and that is by far the most common cau...

Have you tested other cables? 100mbps only requires 2 pairs of wire, while 1000mbps requires 4 pairs. If there's an intermittent fault in a conductor/connector it's possible that it's automatically falling back to 100mbps, rather than fail entirely. Low voltage is also a possibility as mentioned abo...
