You are a kindred spirit. I have: 2 pi NTP servers - one running a GPS hat + PPS wired up, one using a USB gps receiver. a "workhorse" pi - 2 wired ds18b20 temperature sensors, cron jobs, email generators, weather page generator, connectivity monitor. One pi running piubos + nextcloud. One pi running as a clock. One pi running as a wireless temperature receiver. a few floating pis running media center or retropie or other things... just swap in the right USB stick and run.

I use a Raspberry Pi to stream PlayStation 2 backups over SMB by networking the onboard Ethernet port of the Pi to allow access to a Samba Share service running on the Pi. This allows for seamless playback of games with heavy Full Motion Video sequences as the Ethernet transmission is faster than the max throughput of the USB2.0 ports provided on the PlayStation 2. It -also supports auto mounting and sharing of exter…

How fast is streaming cut-scene heavy games like MGS4 to the PS3 using this setup?

Also, for the PS2, how does it compare with HDDLoader and an internal HDD. Relevant for games like Fatal Frame, where you have to open doors a lot, and on the DVD, it takes like 5-10 seconds, but on the HDD, it takes I didn't know we could steam to the Xbox OG, sounds pretty useful compared with the 1hr process to open it up and upgrade the HDD...

I have an old Raspberry Pi 1 that runs headless raspbian with a set of cheap speakers plugged into it and an old usb wifi adaptor. It has only one purpose: to play a wav file of a telephone ringing for one minute. My spouse does not ever have the ringer on her cell phone. So when I am out and I need her to look at her phone, I VPN in to my home network, ssh into the pi using Terminus on my iphone, and 'aplay' the wav…

Similar issue, but I worked around it by setting up one of those find-your-phone apps and whitelisted my number. Now I can just text her the secret code and it makes her phone ring loudly even when it's on silent.

I previously used mine to drive my synchronised Christmas light display. It worked great one year, then for some reason the next year, retrieving the playback position of an audio file in Java was taking nearly a second (previously it was practically instant).

I never figured that out, so I bought a second-hand Mac Mini to power the display instead.

* I made a Raspberry Pi Zero W version of this baby monitor (https://kamranicus.com/guides/raspberry-pi-3-baby-monitor)

* I am using a Raspberry Pi Zero W + Arduino Pro Mini, with a GPS, Sensors, Camera and Radio for a High Altitude Balloon (HAB) project (https://bitbucket.org/ccapo/habpi/src/master), launch pending. A friend is also launching a similar project (https://bitbucket.org/peterkingsbury/neopi/src/master/)

* I am using a Raspberry Pi 3 for RetroPie

* I have a Raspberry Pi 3+ for development purposes, mainly the HAB project since developing on a Raspberry Pi Zero is quite slow

I'm in a college club that uses Pis to run football playing robots. The Pi basically translates instructions from a Bluetooth PS4 controller into commands for a motor driver. We currently 4 college clubs in the league and we play a couple of scrimmages and a championship every year. The robots take big hits in the games(these bots can go faster than we can run) and we've found the Arduino to be the most durable and reliable platform as well as being the most customizable. Here is our club Website: https://www3.nd.edu/~rfc/ Here is a little video about the club: https://www.greatbigstory.com/stories/nbc-sports-intramural-...

Good souls. I took the time to setup a highly accurate stratum-1 not server only to find my ISP permanently blocks udp 123.

I used an ESP8266 and not the Pi for this, but a really really great m/c project is a wireless fan controller for a smoker or kamado (big green egg-style) grill.

I made mine from scratch as an learning exercise, but here’s a similar project using the Pi: https://github.com/michmike/Raspberry-PI-Q It’s

We use it to make, for example, this recipe (with some modifications of our own) on a regular basis with a minimum of effort, and it is one of the most breathtakingly delicious things I’ve ever tasted, let alone cooked myself. We follow his instructions but hold to 180-190 deg until the meat reaches about 138, basting a few times with a honey+whiskey+thyme glaze; also be sure to use a fatty salmon, like (in my experience) farmed atlantic, not sockeye.

> Z-Wave home automation via ZWay: Whats your success with this? I am not referring so much to the Raspberry Pi part - but the actual ZWave protocol and whatever mesh network it creates. Is it reliable? Or do your lights flicker on and off randomly?

I have used mostly light switches, dimmers, and a few isolated relays, plus home power monitoring.

My experience is that it has all been rock solid. I’m using most GE branded in-wall light switches and they’ve been very reliable for me. Misc other brands for the other modules.

I’d recommend it.
