A client that I'm consulting was being ripped off by a local IT provider with pricing for on-premises servers & MS software. I proceeded to rent cheaper equivalent machines off-site. The IT provider claimed the hardware firewall (Fortigate) was not configurable for site-to-site to the new machines directly (could be, not an expert on those). Therefore, I ended up purchasing several Raspberries and configuring them as…

You can absolutely configure IPSec tunnels on Fortinet.

Can I ask, do you perform updates and maintenance on these boxes? How do they perform in terms of throughput with openvpn?

I have it set up to run a project where a subreddit has control over the watering of a live plant in my apartment. The pi runs a reddit bot that reads the votes, and can switch on a pump to water. It also collects data about sunlight, moisture, temp and humidity to help inform the decision about watering.

Maybe I should create a subreddit where people can control a bot that has access to my bank accounts so they can manage my finances, invest some, etc. ;-)

I built a guitar stomp box using a Raspberry Pi Zero to trigger samples with a foot switch. Runs on 9 volts and has a very bright OLED display so I can still see what it's doing when I'm playing in a dark venue.

I have been thinking about doing something similar -- would love to hear more about this if possible!

It's basically a Pi, a buck regulator, a tiny COB USB audio interface and an SSD1306-based 128x32 display. Removed all connectors and replaced them with soldered wires so it packs neatly into a tiny box.

The software is all custom and written in C, using Jack for low latency audio and my own driver for the display (Adafruit makes a Python driver but it eats half of your CPU and is not optimized for i2c bandwidth or high framerates).

Didn't someone do this with Twitch Plays Stocks? Essentially gave them some capital and let the chat decide what trades to make. They nuked the portfolio within 24 hours.

> Next project: 1x Raspberry Pi Zero W to run Unifi Controller

Ugh, have fun with the dependency issues. An easy alternative is to run a Unifi docker image. Currently running it from a Debian VM when needed but looking to move it to an alpine vmm on my OpenBSD APU2. The Linux image is the same as the cloud key so you can roll your own cloud key and use the unifi app.

Here is the image I use though there are others: https://hub.docker.com/r/jacobalberty/unifi/

Earlier quoted context omitted.

Did you also acquire an ASCAP/BMI license for the music-on-hold? A lot of people are unaware that is classified as a public performance of the music and requires a license. Unless you are playing royalty-free music, in which case you are fine.

I purposefully sought out royalty-free music. As the person who set it up, I did not want to risk being culpable for anything. (When it was first set up, my boss kept requesting that I add various catchy songs he heard on the radio to it, and I kept having to explain it's not legal.)

I use the hold music that zendesk made. I think it's pretty neat. I doubt anyone really loves it, but no one seems to dislike it.

I live in an apartment with quite strict fire-protection standards. Due to the fact that I have a cat that absolutly loves to go outside, I needed to find a solution for him to get outside without a catdoor trough my door.

So I installed a fire-protecion-approved door drive that is hooked to a raspberry pi. Another raspberry pi then analyzes a video stream and detects my cat. If my cat is in the frame for n amount of time, a message is sent to the pi conntected to the door drive and the door opens up slightly for him to get in.

I use it to run my automated watering system in my garden.

I used to use an esp8266 but replaced it with a Pi after a lightning strike destroyed it. The Pi is just so much easier to write software for and it's been no less reliable in practice.
