Re: Ban from Raspberry Pi forums. [Self-imposed.]

I have handed myself a 2-week ban from the Raspberry Pi forums, in solidarity with @DougieLawson... In the meantime the Raspberry Pi Foundation might want to consider whether some of that £78M grant needs to be spent replacing - or even better, nurturing - its volunteer community. Ditto. Ban seems ...

Re: Need recommendation for lighting project....

There is a ton of LED strips out there on the market, of all colors and multi-colors. Even Walmart.com has lots of inexpensive strips and some are waterproof. As for "step-proof', that is a vague term. I would be inclined to try to keep the strips out of harms way but the devices themselves are rugg...

Re: Best USB camera for Pi 2 as a home security camera

The "Noir" camera is as good as the regular RPi camera...just without an IR cut filter in the way. It tends to render normal lighting with a red cast, No camera can see in total darkness unless the subject is a bright IR emitter and so the Noir, like any other, requires an IR light source to illumin...

Re: Something missing or something missed?

For the most part, sudo apt update && sudo apt full-upgrade -y will bring you up to date. However, it won't install new software packages that were not included previously (it only upgrades existing packages, with the exception of replacing deprecated packages). So this means that burning the new i...

Something missing or something missed?

I haven't seen any announcement on these RPF forum pages regarding the latest Raspbian release and only knew of it from the announcement on DistroWatch. This has been fairly typical of previous releases. The Downloads pages here very quietly announce the updated release. Seems odd to learn of someth...

Re: Pi Gui For Electric Car Charging Point

1. Not your guy here...just an old fart in the US. 2. RPis have no native analog ability so the slider idea would require an added A-D converter. 3.

Re: MAC number read by Router Edimax WiFi

If the RPi is powered and the rj45 is connected, even if the Edimax is doing the work, the router will see both MACs. Sometimes, and on some routers, they don't refresh their client list as often as we might like and even if one is not connected, it may remain in the list. It is not an RPi problem.

From reading a review on the SmartPi, it is designed for the purpose of measuring energy consumption of an electric utility customer like a home or very small office. It is much like the EmonPi. The only way the SmartPi could be of use in a car would be to measure the unrectified AC coming off the a...

Your situation does not sound too weird...uSD failure is related a bit to frequency of write cycles but can happen at any time.

Re: HDMI Output not working

Before you run out to purchase a new RPi. you should download "Raspbian_latest with Desktop" and test it with the Samsung. Your problem is most likely a problem with the OS on the uSD card. If not that, perhaps the HDMI cable. If you have important things saved, you should either transfer them to a ...

Re: Help, how Raspberry manage Time/NTP/RTC? Please RTC experts read this!

I have both RTC and Ethernet connected. I keep the RTC only because we have frequent power failures and occasional internet failures and I depend on cron to trigger the job I have for the RPi. It suffices for my need but I do not know the frequency with which Raspbian updates from NTP. I think the f...

Jessie is out of date and has been replaced by Stretch. Updates to Jessie may get hung up on the Stretch repos. Download the 10-2018 Raspbian_latest and it updates fine.

You gamble and this time you lost on aliexpress. A good, ethernet-only USB adapter from Plugable bought from Amazon did not cost much but works fine on a zero. Other name brands may do just as well but stick to main line retailers like Amazon or Adafruit.

While I have used only "add-on" switches in the 5v line, it has not been a good experience...at least in my environment. At currents of an amp or two, the voltage drop of small cables and electrical contacts can be enough to drop the RPi below its limits and get that dreaded lightning bolt. Switch c...
