[Solved] MAC address conflict when using 3-port USB/1 port NIC device on Pi Zero

Have been using a 3-port USB hub/1-port NIC connected to a Pi Zero, to provide a cabled ethernet port. All was well when only one of these hubs was active on my internal network. However, when a second Pi Zero + hub was added, there were strange problems on my network, with periods of either one or ...

Re: Standard or noir for dark room LCD reading

I've been running two Pi Zeroes for around nine months to remotely read my electricity and gas meters. I'm using motioneyeos with a Blinkt module attached to the GPIO pins. I use crontab to switch the Blinkt on 10 seconds before each hour, shoot a still picture, then switch off Blinkt 10 seconds aft...

Re: [Headless] WiFi dropouts - Bin the EW7811Un/Switch to Pi

Hi Rob, The replacement Edimax EW7811UTC adaptor is holding up extremely well, with no WiFi problems since I last posted. The adaptor is accessing a 5GHz wifi channel on my router, and is using a static IP-address. Meanwhile, after many weeks I have not seen a single wifi problem with my RPi running...

After a long absence in posting on this topic earlier in the year, I'm able to report success in running several Raspberry Pi-s with either Edimax EW7811Un or Farnell WiPi wifi dongles. I'm using the 2014-09-09 version of Raspbian Debian Wheezy, no additions to modprobe.d, no need for crontab keep-a...

Re: Surveillance camera based on BuildRoot and Motion

Downloaded ccrisan's latest 23 November MotionPie image and now have two model A+ boards successfully running with the Pi CSI camera. Haven't tried the embedded software upgrade option though.

Raspberry Pi A+ USB port bent pins

A word of warning to users of the new RPi A+ of a potential problem with the USB port when used with certain USB plugs. During the setup of my first A+ two days ago, I plugged an Edimax WiFi dongle into the USB port, and found it would not mate correctly. On removing the Edimax I found that all four...

I’ve tried many of the solutions proposed on the raspberrypi.org forums and also on many other internet forums. For example: - using the 5.2v/1.1amp port on a PiHub to s...
