I have Raspberry Pi and I mainly use it for VPN and piHole. I’m curious if you have one, have you found it useful? What do you do with your Raspberry Pi?

I'm working on turning it into a IR emitter to control some stuff that I have that lack remotes. I have another I've loaded snips onto an will be experimenting with soon - I'm currently using a PlayStation eye for the experimentation, but will have to get a better microphone/speaker. I wish I could hack a dot/echo/etc. and use their microphone/speaker, but meh, I'll take what I can get. Also, the IR pi will probably drive some ambient light as well.

  > I'm working on turning it into a IR emitter to control some stuff that I have that lack remotes That's really neat. Please share some details – I was planning on buying a Broadlink IR/RF device for that purpose.

Unpowered in a drawer.
- robin_reala · 2648 days ago
  Yep. As much as I’d like to play around with it, I have no projects in mind that aren’t pure-software and easier on my laptop, or just end up filled with pre-made solutions to save on support time. Shame, but there you go.
- elagost · 2648 days ago
  If yours has wi-fi (Pi 3 and above or Pi Zero W) you can always just leave it plugged in somewhere innocuous as a pi-hole. It's super useful and takes almost no time to set up, provided you can change the settings on your router to use it as DNS.
  - elcomet · 2648 days ago
    I'm scared that if the pi is down then the whole internet is down (i'm not always home with my family, so if I'm away I couldn't fix it). How do you manage failover ?
    - iforgotpassword · 2648 days ago
      How do your manage your router failing? Do you have a second one in hot standby? Sure, the pi would add a second point of failure but personally I never had a router or rpi fail, so I think the advantage of running a pi hole outweighs that increased risk.
    - stordoff · 2648 days ago
      FWIW, I ran Pi-Hole on a RPi for about six months, and it was flawless (long enough for me to forget the root password :p). One option would be to set up two Pis, and distribute both IPs in DHCP. If one is down, or can't resolve, clients will fall back to the other one. The chance of both being down at once (unless it's something that takes your network down) seems low, and the cost of a Pi Zero W (~$10) wouldn't add much.
    - elagost · 2648 days ago
      If necessary I can SSH in (if the pi is on) and troubleshoot. No one runs a business out of my home so Internet isn't super critical, and the smartphones have data connectivity if need be. I have a couple fresh SD cards in storage and take quarterly SD card images, so if it fails I don't have to rush out and buy anything. If the pi itself blows up, I can talk my wife through changing the DNS server on the router config page from her laptop, or she can just wait until I get home. Not a huge hassle. Even so, normally you can set a fallback DNS server on your router, and you could have two little Pi Zeros on a plugstrip in a closet somewhere! (Or just set the fallback at opendns or something)

Media player connected to tv. (Kodi or Elec, I can't recall which) What I found really neat about this is that if you use the HDMI connection, there is some automated setup/control that allows my tv remote to control the PI. (through the HDMI connection) But also, the smart phone app for Kodi remote control added a new layer of interaction with the media player that is just sort of unique and unexpected. (everything worked so easily)
- colechristensen · 2648 days ago
  The remote control tech is CEC. https://wikipedia.org/wiki/Consumer_Electronics_Control
  - RobertRoberts · 2648 days ago
    Thanks, forgot what it was, and didn't have time to dig around in the docs where I first ran into it. The fact that this is not widely advertised as a feature is surprising. It made remote control automatic instead of having to hack something together.

I have several, I use them for multiroom audio with snapcast (mostly with USB DACs although one has a DAC hat. Some have temp and humidity sensors, one has the rpi cam. One has a always on vpn connection and transmission running. For a while I used one with a Parsec client and cloud gaming. However, I use a Odroid XU4 for all the big stuff (home assistant, NAS, nodered, mopidy, etc.)
onion2k · 2648 days ago
I spent a while figuring out the cheapest possible way of doing front end dev for a series of blog posts (that I never wrote) . The result was using a Pi3B+ and a lot of open source tools, Github and Netlify. It works so well I'm still using it for a ton of dev.
mvip · 2648 days ago
I got a bunch of them running Screenly ( https://www.screenly.io ), so I'd say that's a good use :) Also, I'm using PiHole and Home Assistant. Disclaimer: I'm the author of Screenly.
vanadium · 2648 days ago
Pi-Hole, RetroPie, and for my 1st-grade son I installed Kano OS for his first computer. I see a couple of Pi 4s as upgrades in my future. Also looking to get my SDR rig up and running on one of the other Pis i have waiting to be used.
- dgacmu · 2648 days ago
  Anything you've learned to share about having it as a computer for your first grader? I recently set one up for my daughter, same age, but haven't put much thought into the software side yet. She's played Minecraft-pi a couple of times, we made the cat meow in Scratch, and we used it to watch a movie the other day, but that's it so far.
  - vanadium · 2648 days ago
    Since I only installed the Kano OS image on a bog standard Pi 3, it's basically this without all the accessories. https://kano.me/store/us/products/computer-kit It's great that Kano makes it available standalone. Kano OS has all the activities built into the image, including visual coding of Minecraft and other tools, and guided lessons around using the Terminal. Chromium and LibreOffice are also installed by default. There's also a curated app "store" like experience to add new games. Installing CUPS to add our printer to the Kano OS Pi was pretty straightforward, so he also uses it for personal writing and printing out stories. It's really engaging for our son, and provides ample time for parent-child learning opportunities to boot. We ended up getting the Pixel Kit while we were at it, and Kano OS picked up on it immediately and exposed all the lessons for it. Hoping their move to Windows 10 doesn't leave their Kano OS image locked to a Pi 3, though. I'd love to upgrade his Pi to a 4 soon. Kano OS Image: https://hello.kano.me/downloads/

VPN
carry_bit · 2648 days ago
Media center & TV PC. I have a 4 TB external hard drive connected to it (and swap on it). Using a custom compiled kernel with zswap support, browsing the web isn't that bad with the 1GB of RAM on the 3B. I've also hooked up an RTL-SDR to it and ran rtl-tcp instead of needing to run a long USB cord.
amingilani · 2648 days ago
I used it to monitor ADSL device status[0], also created a DIY timecapsule for MacOS[1] — these were all in the past, though. Currently the Pi is on my roof, connected to an SDR. I sometimes run rtl_server on it, and listen around. Although it's been a hassle, since I have to run upstairs and disconnect it everytime there's a storm. Also, listening to the device over WiFi means I get really laggy control over my SDR. I'm planning on replacing the Pi with something better powered.

- valent1ne · 2648 days ago
  You could probably automate cutting the power with a relay switch also connected to the pi. Just scrape weather data, and if you expect the storm, trigger the switch.
  - amingilani · 2648 days ago
    I'm actually more concerned about lightning strikes hitting the antenna, frying the Pi, traveling down the Ethernet cable and frying my router. I'm still a ham in training but I've been told that it's best practice to disconnect the antenna and isolate it from your setup. Some hams as far as placing their connectors in glass jars. I don't want to use a relay on the antenna cable because 1) it'll pick up RF interference, and 2) if a direct strike hits it, there'll be enough energy to jump the gap in the relay anyways. I might figure out a more permanent solid-state solution in the future though. Like I said, still learning :)
    - wrycoder · 2648 days ago
      Ground the antenna.

hlfshell · 2648 days ago
I've made some interesting projects over the years - only a writeup on a few of these, and some are in pieces and in various states of disrepair after moving so much. Some write ups on larger projects: 1. I used a raspberry pi to coordinate the firing of multiple cameras, and then had the pi upload to a cloud service that would stitch them together to an "infinite zoom" super selfie. https://medium.com/@thekeithchester/gigasnap- a-prototyping-story-efed72099d32 2. I created a library that made it dead simple for a raspberry pi to communicate to arduinos, and used that to control a lot of hardware projects, like little robots. https://medium.com/@thekeithchester/serial-synapse-94a114aa2... 3. Raspberry Pi's controlled the heartbeat detection (controlled lights and music of your booth) and conductive paint controller (I built it and still don't understand the meaning) for this art piece. https://vimeo.com/207047769 4. I had a video / text message doorbell a couple of apartments ago. https://github.com/hlfshell/doorbell 5. Used one as an MQTT hub for numerous IoT projects. I created https://github.com/hlfshell/mqtt-scheduler to schedule MQTT jobs for things like the arduino powered garden controller (lights + water pumps) I built for my wife. https://github.com/hlfshell/garden-relay 6. This never got off the ground, but when Pokemon Go had first launched and was super popular, I wrote a slackbot that would alert everyone in the office when pokemon (outside of the super common Rattatas and Pidgeots) was nearby. I was repurposing that code to make a portable Pokemon radar that would jump a false account around the area around you, thus hunting down pokemon for you. https://github.com/hlfshell/pokemon-tracker It never got far as the game got super stale quick.

    Nice! Thanks for the link. Our goal was to hit a cool shot a mile away on a target in the middle of a giant concert for a "I was there!" memento shot. Good to see it in practice somewhere. Unfortunately the sales team didn't understand it, and what sales team doesn't understand sales team doesn't sell. ...I'm very happily in another company that gets tech - but man I wish we could have sold that project. The effect was really cool when we had it working fine.

Running piAware for flight tracking https://flightaware.com/adsb/piaware/
- sucrose · 2648 days ago
  Is there a benefit to personally tracking flights instead of querying 3rd parties?
  - matthewmcg · 2648 days ago
    Most of the services (FlightAware, Flight Radar 24, ADSB Exchange) get much of their data from volunteer-operated receivers. If you feed your own data to these networks, you get several benefits including multilateration capability (computed location for planes that don't send their own GPS location data) and free business accounts on FlightAware and Flight Radar 24.
  - gleenn · 2648 days ago
    Perhaps they are in a remote location that doesn’t have data?
  - markdeloura · 2648 days ago
    FlightAware in particular gives you access to a greater level of data and services on their site if you're an active contributor via a PiAware. Also, honestly, it's just fun fooling around with the antenna and software setup to maximize the number of flights I can see :)

        >I'm sorry, what? "Of a number of different solutions, Amazon has consistently delivered the best UX for streaming, shopping, and wireless music playback. Why would I switch?" I view shows on Prime with multiple seasons all the time.
  - zoul · 2648 days ago
    So far I have not found anything broken yet. I think I would go for a whitelist in that case.
    - Tehchops · 2648 days ago
      I tried that in the past. Unfortunately shopping and multiple FireTV apps would break due to non-trivial data being sent from multiple domains.

I'm totally naive with Raspberry Pi..can someone comment on the following project: Is it possible to put a glass eye behind a portrait of a one-eyed pirate and make its eye move around/follow whoever enters the room? A friend has a glass eye but nothing to do with it.
- amingilani · 2648 days ago
  Lemme think. A camera that observes the room from the portrait, anyone that walks in is a dot on a plane, and it points the eye at the point on the plane. Should be doable. Yes, the Pi should handle that fairly easily. The part that you'll have to figure out is making the eye ball rotate. There are GPIO pins on the Pi, so you can get the commands out, but you'll need to build the eyeball component yourself.
  - HeyLaughingBoy · 2648 days ago
    Probably not. Servocity has x-y gimbal controllers. If you can find one small enough, it could control the eye.

jchw · 2648 days ago
Right now: I use it as a Flashrom rig, for flashing BIOS chips. The new Raspberry Pi looks powerful enough to use as a media center PC, I ordered one and want to see if it can do that well enough (read as: I’m curious to see emulation performance.)
- fsagx · 2648 days ago
  I've been happy for a year or two (not even sure, now that I think about it...) with two Pi3s running openElec. Both run over wired ethernet to SMB media server. I'm generally stingy with my storage, so I usually opt for the 1080p file sizes. I don't know how well or if it can handle 4K.

I have a small Internet kiosk for one-off browsing and guests. Currently, mine is running on an ODROID-C2 but the Pi 4 should have more than enough performance for one. My setup is a stripped down install with a minimal window manager. There's only one icon for launching Firefox which is configured in an amnesic mode. The DNS is set to my Pi-hole.

We use it as a front end to our Church's AV system. It runs a GUI written in Python with PySide that controls our cameras, hyperdeck recorder and vision mixer. It also controls the power switches for the system, and the blinds.

  - llamataboot · 2648 days ago
    Thanks! A first version of the code is on github: https://github.com/estiens/confessional_booth It was originally part of a confessional booth taken to Burning Man in 2015. Since then it has evolved and become part of my smart home stuff. I was intimidated when I started as it was my first "hardware" project, but the rotary phone part was pretty easy! Just a little switch that turns on and off the number of times of the number dialed basically. It actually has a (new) microphone wired into the mouthpiece and it uses the receiver original speaker ired to the pi sound output. (At the time I knew nothing about Linux so I think getting pulseaudio working correctly took as long as everything else!) Those aren't working currently, but eventually I plan to integrate both the rotary dials and voice recognition and "scenes" So like, dial "721" for light control. Voice: "And what are we doing with the lights today..." Me: "Make the outside light purple" and it is done. I have custom voice recongition for things like that working with Mycroft, so it will just be a matter of joining the two projects!
    - llamataboot · 2648 days ago
      As a bonus, since it was originally designed to work in the desert without a screen, it can do things via a weird analog interface. For example, if I press the hangup button 10 times in a row and then dial a number, I can get a report of how much memory is left on the device, etc.

I use them as controllers/monitors for remotely managing a 3d printer farm. At about $40 total extra per printer for the pi and associated hardware, and an open source utility called "octoprint", i'm able to remotely upload, monitor, cancel/pause, and have a camera feed to each printer. They also give some additional nice-to-haves by allowing me to upgrade the printer firmware remotely, and get very accurate print completion estimation times.

Mine is running in my attic, hooked up to three antennas on my roof: 1. A GPS antenna which provides an accurate “stratum 0” time source. The pi runs ntpd and provides time for all devices on my network. 2. A home built ADS-B antenna for receiving position reports from local aircraft and airliners. Interfaces to the pi with a USB SDR. Pi runs dump1090 to provide a web visualization of local air traffic. I also feed FlightAware with this info. 3. A home built VHF antenna for listening to airband transmissions. Second SDR. Pi runs scanner software and an IceCast server for clients on my network to connect and listen. The pi also has a temperature sensor that logs once a minute so I can plot my attic’s temperature and I can have it alert me if it gets too hot.

My Raspberry Pi 3 works as a CUPS print server connected to a laser printer, as a pi-hole DNS server to filter ads, and as a ssh entry point (with dynamic DNS). I would use a Pi zero, but Ghostscript is not too happy when printing large documents on a single-core processor with 512 MB of ram. I still have to find the time to set-up a backup server on it (and decide which software to use).

I'm planning on adding a GPS adapter and probably a gyroscope/accelerometer so I can track location and motion at the same time. It's mostly just for fun. Maybe one day I'll add some kind of analysis to it. It might be interesting to track location, motion, and car status in order to predict mileage or if the engine light will turn on.

Doorlocks of our hackerspace has been RPi controlled almost since the original RPi came out, maybe 2013. Nowadays we got 4 doors on 3 RPIs (internal and external), with over 200 members that has access. Using MQTT to communicate with our membersystem since 2016 or so.

I used mine as a NAS for a while with an external USB HDD and a samba share. It was also set up to be a VPN and pi-hole. I have a pi zero that I use to flash coreboot on laptops. My PS3 isn't doing so hot as a media server client for my NAS's movie library - the network connection is poor, the interface is fiddly, and it can't load subtitles embedded in files. I was going to buy a pi3 to replace it as a media server client and hook up an external DVD player, but now I'll be getting a pi 4!

The coffee machine in our office is controlled by blockchain NFTs and a Raspberry Pi: Once authenticated, an owner of the NFT can select their coffee type on their phone which then signals the Raspberry Pi to make whatever coffee type was selected by jumping the contacts that used to be pressed by the machine's buttons (which have been removed). It's a cool gimmick, fun to show off to visitors, gives us a nice record of who is making coffee (since each NFT's owner is unique and trackable), limits users to those with the NFT without us having to build usernames/passwords, and is also how I make my coffee each afternoon.

  Very similar to what we have in the office as well. The difference is that we are using bluetooth and NFC of the mobile as authentication method.
- trimbo · 2648 days ago
  Does it record on the blockchain who took the last cup of coffee and didn't make more? Everyone in every office would pay good money for that.
  - quartz · 2648 days ago
    It doesn't write individual orders to the chain. It could if we funded a wallet to pay the gas to write those records but right now it just does authentication of NFT ownership to grant access, which is conveniently free. The history logs are stored locally.

  Did you do some work to run 100% from ramdisk after boot? Conventional wisdom says that the SD cards should fail eventually from log writes, etc.
davidb_ · 2648 days ago
I've got 5. I only actively use 3 of them. 1. Media player connected to projector running RasPlex - this software is outdated enough and buffers on some high bitrate content that I should buy a replacement device, but it still works well enough. I tried upgrading to a newer raspi and wasted an hour trying to get it to run, then gave up. So, I still use my old one. It still gets used daily and works well enough (only issue is the buffering on occasion). 2. RetroPie - I rarely game, but it's cool to be able to turn this on and have a library of all the games I played (and those I never had) from childhood. 3. I use the third one as a networked LED marquee controller (HUB75 panels) with this software: https://github.com/hzeller/rpi-rgb-led-matrix The other 2 I just have sitting on my desk and occasionally use for small dev projects or to test out some new project I read about on here, hackaday, etc. An ongoing project that I haven't made much progress with is an automated turret that squirts squirrels with water. I made something similar in college (a "paintball gun" turret with openCV blob detection/tracking) that had decent performance. Now that openCV on rpi can outperform my old college laptop, I want to setup the pi to detect squirrels, track them, and keep them away from a bird feeder/plants in my backyard.
- ncarroll · 2648 days ago
  Would that turret will work for pigeons landing on my balcony? Or better yet, to protect my air space by squirting them on a fly by? That'd be some sweet fun. :-)
  - mft_ · 2648 days ago
    This makes me sad. Pigeons get a bad time, but they're lovely birds of you spend some time observing and maybe even interacting with them. We had an obviously-paired couple visit our balcony most days for a couple of years. Please don't be (thoughtlessly?) mean to them.
    - sersi · 2648 days ago
      I like Pigeons and don't mind them except when they visit my balcony at 7am in the morning and wake me up (we only have single pane windows and no way to change it since we're renting).
      - Tempest1981 · 2648 days ago
        I keep some earplugs nearby for this situation. The birds can be persistent.
    - ncarroll · 2648 days ago
      Don't be sad on my account. I actually like them very much. They are funny and persistent. I watched one yesterday try to outsmart a crow for a piece of cheese. That she even tried was pretty courageous. We have an obviously-paired couple living on the roof of the building next door. They are very sweet and would be welcome to visit if they would promise not to nest. But they won't. And the first pair of baby pigeons we sheltered was the last pair of baby pigeons we will be sheltering. The mess was indescribable and everyone was so comfortable they all wanted to raise families here. Horrified, I chased pigeons from our balcony during mating season (circa any time it's warm outside) multiple times a day for three years before I regained control of my tiny kingdom. Pigeons have the whole outdoors to nest in, the city even maintains a pigeon house on top of a building just across the way. I have my balcony...

  Do you have any more information or a write up on what you're doing with Twilio and voicemail? That sounds sort of interesting.
  - djhworld · 2648 days ago
    No write up unfortunately, I actually made it a few years ago as I was getting a lot of recruiter spam calls, but ever since the GDPR came in that has stopped. I don't receive that many calls these days. I have my (cell) phones voicemail set to my Twilio number. When a voicemail request hits Twilio, it calls an endpoint hosted on my Pi, which then just calls the Twilio APIs to 1. tell the caller to leave a message after the beep 2. record the message 3. use the speech-to-text API to transcribe the message 4. send me an SMS message with the transcription It's really just an ersatz visual/text voicemail service that I think iPhone users get. Also the Twilio speech-to-text transcriptions are hilariously bad, I don't think it copes well with UK accents :)

  Energy use, probably. I bet the RPi uses a ton less energy than your linux server. But in this case that's not really a tradeoff since you'd be running your server in addition to the RPi.

    Boo! Might have to reconsider then. I used the Pi Zero W for FullPageOS for a while but performance was absolutely terrible, recently switched it out with the Raspberry Pi 3. The Pi Zero really has an awesome form factor, but many of the projects I come up with either require more performance (i.e. needing a Rasperry Pi 3) or are simply better suited for a microcontroller such an ESP32 or ESP8266.
    - tjoff · 2648 days ago
      I guess it depends, but having the unifi controller on wifi isn't always the best of idea. If you misconfigure the wifi or just change the ssid/password the controller looses access as the settings are applied. And now you can't even connect to the controller to fix it.

  - myelin · 2648 days ago
    Seconding this... it'll just barely run on the Zero W, but you need 64-bit Java to remotely access your controller through unifi.ubnt.com, and there'll be long delays whenever the database needs any maintenance. (I set up a Zero with the Unifi Controller -- connecting to the LAN using a Chromecast Ethernet Adaptor -- about a year ago, and had this problem, so I switched to a 3B, and all is well now.)

    - lwansbrough · 2648 days ago
      That "open stuff" generally speaking is either an ODB-II port (which as I understand it is generally limited in diagnostics and communication in modern cars) and the other is the C2 Radio harness (which plugs into the back of the infotainment system.) These systems exist on all modern cars. The C2 radio port gets you direct access to the vehicle's CAN-Bus system, which itself is generally segmented into a high frequency (safety critical systems: drivetrain, drive-by-wire steering if applicable, braking, etc) and a low frequency system (door locks, sound system, windows, etc.) If you reverse engineer your vehicle's CAN protocol (each manufacturer uses their own codes on a standard CAN transport protocol), you can issue commands to it directly from your Pi.

    It is a nightmare! I just finished fighting with it this weekend. The controller only officially supports ARM 32, and the mongoDB dependency only supports ARM 64. In the end I I used a 64-bit Ubuntu, 64-bit mongoDB from the mongoDB repo, and downloaded the controller deb from the Unify site, which is apparently architect agnostic.

- prkr · 2648 days ago
  I'm interested in learning more about your LED light alarm set up—I had a similar idea a while back but am less familiar with the world of Raspberry Pi.
  - jepler · 2648 days ago
    Thanks for asking! I haven't documented it anywhere, and the source code isn't suitable for consumption by others. But, I can tell you about the basics. I bought a "12V" LED strip intended for automotive use, and created a simple circuit with a +12V DC supply and an NPN transistor. By hooking the NPN transistor to a PWM output on the Pi's I/O (via a resistor), I can control the LEDs from nearly full darkness to their maximum brightness. Here's a tutorial that covers the same ground: https://dordnung.de/raspberrypi-ledstrip/ There's also a switch for "disable alarm no matter what" and "turn light on/off right now". (I also use it as a nighttime reading lamp, with the added bonus that it starts ramping down the brightness after about 25 minutes and turns off after 30: a good reminder to go the f--- to bed) This all hooks to some not very interesting software to listen to the buttons, carry out an alarm schedule, ramp the LED intensity up and down, and so forth. In my case, it's written all in Python in a sort of timer-and-event-driven style. Since this pi has wifi, one part of a traditional alarm clock is missing: it sets the time from NTP and applies the standard DST rules to obey summer time; there are no controls to set the time, and even after a midnight power outage it'll generally alarm at the right time in the morning, as long as power came on at least a few minutes before the appointed minute. I've had a number of variations on homebrew light alarm over the years, AVRs and arduinos, TRIACs switching standard incandescent lamps, RGB LEDs simulating the sunrise color sequence, etc. It's the sort of project you can always do again and explore more of the problem space and find what works best for you.
    - prkr · 2647 days ago
      I appreciate the writeup! I had originally looked into using the Arduino for this project but the prospect of handling times and daylight savings seemed like more crunch than I wanted to dig into. NTP is a good solution. Have you found waking up to light a good alternative to standard alarms?

I successfully figured out the baud rate and captured bytes, but never figured out how to control the treadmill motor board.

Two things, working on more. VPN router and a doorbell to desktop-notifications box. I like listening to music on noise cancelling headphones sometimes when I work. I wouldn't hear the doorbell in that case, so I have a pi with a mic that sits close to the doorbell. If the noise level goes past a certain threshold for a few samples, it sends a command to my workstation where a script sits and triggers a desktop notification. Works pretty well with very few false positives and all "I might miss the package delivery guy" anxiety is gone while I enjoy music.
