Re: recovery from power failure

A primary cause of your confusion regarding the RPi's start-up is that it lacks a Bios program that runs automatically at reboot. On my PCs there is an option in the Bios where I can choose to have it wake up, or not, after a power failure. It is a feature of the Bios software. I leave it "off". Lac...

Re: power supplies

Just rec'd the power supplies in the mail. They are tiny...0.93"x0.7" x0.53, Hard to believe they are so small and have the capacity for a RPi zero and certainly for the Node0MCU I need to drive. They won't fit inside an official RPi Zero case but they could easily share one of the larger enclosures...

Re: Help with pie home network.

Although in a "civilized" rural area with expensive AC power, I have no hard-line internet service and resort to the satellite for internet. I hate it but it is the only show in town. My phone line is direct buried copper wire and the house is too far away from the street to run conduit for the fibe...

Re: Stretch no longer boots after update/upgrade/reboot

In the first place, you are probably putting too much time and effort into resuscitation of the existing uSD. Get a fresh one, download the latest Raspbian desktop and use Etcher to burn the new uSD. Save the old one and copy any important files to the new one. As stretch is now obsolete, you will b...

Re: Thunder activated

It might be easier to detect lightning than thunder. I think some of these exist for sale and are based on static RF spikes caused by lightening.

Re: Protecting a PI4b+ PSU connection with a fuse?

Fuses are well protected by semi-conductors...no sarcasm intended at all. Fuses are intended to prevent fires, not to protect the downstream devices. The time required for them to overheat and blow is much greater than the time required to fry the downstream semi-conductors . If you intend to introd...

ISP modem-router combinations add an additional complication to your picture, as well as possible insecurity if you don't use your own router downstream (your ISP or the Gov't. can get into your LAN easily).

Re: Pi-hole: Unable to log in via SSH.

In using pi-hole, I have not seen any web interface capability for changing the host RPi password.

Re: Does PI 4 come with Real Time Clock?

When I put my solar water heater on the RPi for timing control, initially I thought an RTC would be essential but soon realized that the RPi would get time info from the internet (NTP) and there was no way the back-up power would come on if AC was down. As soon as the AC returned, the modem and rout...

It might be more helpful to mention that the files in question are .zip files rather than just adding to the confusion. The .zip files don't run on arm without further manipulation either and there are instructions for unzipping and burning there as well.

You are a bit short on sharing information. Do you have an RPi already, or not, and which model?

The 3B wireless antenna and range is pathetic compared to the 3B+. Distance and obstructions may be at work here. Unless both systems are right next to the AP, it is 'apples and oranges" to compare the two.
