Raspberry Pi - Who's gonna have a dabble?

[Jim the Sunderer]

I've a Pi Zero W as a wee web server, conveniently I power it from my router's USB port. The USB power measuring device shows it using between 0.8 - 1.2w which is handy.

Nifty things for a few quid.

What do you host on it?

I added a miniUSB to Ethernet adapter for that reason (and as a plus, it also brings a couple of additional USB ports).
Configured Pi-Hole to use Eth0 and not wireless.

Currently getting my modem/router to actually use the Pi-Hole for DNS...

Why didn't I think of that?

Picked up two low end PI's at Norwich's Cex for £18. Very pleased...now trying to find a use for them

It’s a shame that you still have to buy the POE hat to be able to power them with POE. Surely it could be incorporated into the board

What's the chance of using an original or pi2 as a synth for a USB midi keyboard?

I've got an m-audio keystation I bought for the kids to play on, but the DAW software it came with is a PITA to use.

Has anyone tried to use a pi to play on?

Is anyone running the unifi controller on rPi?

I have just configured my Pi3-B running Pihole to use the DNS over https (using Cloudflare). I had a "doh!" moment when writing out the cloudflared file, since I forgot to sudo....

I am astounded by this little thing!

Is Pi-Hole running DHCP?

I am a bit stuck on mine, as the Pi-Hole doesn't seem to be providing IP addresses after I swap DHCP from my modem/router to the Pi-Hole...

You can just run the DHCP server that comes with your Linux distro separately from Pi Hole.

I have a friend that did this on 1GB Pi. He found the controller burned RAM over time and needed a reboot after 5 days or so. He moved the controller into AWS and discovered it could run in a 1GB machine if SWAP could be added. He suspects a pi with >1GB would be fine.

[thebraketester]

Cool. Thanks for that.

I have just realised that the square hyperpixel touch display that pimoroni sell is more or less the same size as a light switch. I now have visions of an embedded screen displaying.... Something. Would be awesome if it were to control the guess lights... Hmmm....

First step is to check that a zero and the screen will fit inside a single back box...

[Paper Lawyer]

I ran the unifi controller on a pi (I can't remember whether it was a B+ or a pi 2 (I have several)) for several months without an issue. However, I recall an arm support issue (I vaguely recall it being a bit of a faff) and I picked up a cloud key on discount in the end (it wasn't essential to do so).



Mind you, I am a sucker for unifi kit (6 APs, 4 switches, USG, cloud key...)

I don't use the DHCP server, though it is enabled. I might give it a go for guests, but I have all my devices on static IP's.

Why would you want the pi to be giving out up addresses? What’s the benefit of that?

Not sure of any benefit as such, but why wouldn't you?
For my small home network it works a treat.

[thebraketester]

isn’t that the job of the router?

Because my router (provided by the provider) does not allow me to define the DNS address (which in an ideal world would point to the Pi-Hole), so the other option is for the Pi-Hole to take over DHCP from the router...

[Nimby]

FWIW I have my router as DHCP server, setting RPi-PiHole as primary DNS to clients and itself as secondary.
The router uses my ISP's DNS server.
PiHole uses Google DNS server. That way I can rebuild the RPi (or it can crash, as it does occasionally) without affecting clients.

Also note- if you're running Buster version of Raspbian you have to type "pi.hole/admin/" in the browser for the admin console. "pi.hole" by itself no longer works.
