    I took the easy way out and used the LED that is on the board. :)

    I can't think of any stupid RPi tricks, but I use an RPi 3 to run my VoIP home phone system - running RasPBX (essentially Asterisk/FreePBX).

    You can page the entire house, call or intercom between extensions, and incoming calls ring all phones. If you have kids, get them a number and route calls to their extension! Best of all, the ability to blacklist single numbers, an entire area code or exchange is very easy to do.

    I am learning to program in Python on the Rpi. I am planning on stacking several of them together, and use them in the shack for various tasks. One for APRS, one for HF digital modes, one for loggging / DX spotting, one for shack lighting control, etc... the Rpi is a great little processor, but when you try to do more then a couple of tasks at a time it starts to slow down. They are cheap enough so having a separate pi for each task is not that expensive.

    Especially if you buy the older Pi 2 or B+. I've been seeing them for $10-20 on Ebay. Works fine for projects that don't need the "horsepower" of a Pi 3....

    I must be getting lazy in my dotage. I recently bought a TFT touch display for my 2+ and am at a loss to explain why o_O Yes, there are possibilities with GPIO, SPI and other interfaces, but I'd rather have a cheap, low power computer that can act as a router, file server or something else that needs more guts than RPi.

    What I really want is a really cheap, small, and powerful computer similar to the Intel atom. Must have 3+ GigE NICs and at least SATA.
    Oh, and it needs to "just work." I'm getting old and cranky, I've spent a lifetime in IT and don't find the 'mystery' all that exciting anymore. Unless it's making an HP superdome supposedly running linux a solid, upstanding citizen. :D

    Me too. VMS, PDP-8, add a few years and here we are.

    Ive started using cast off computers. Dell 960's? $<30 running linux. Wife machine runs Windows, I actually farm work on hers out to the local small computer shop.

    My Pi has been a real treat. Yes, it's a one or two app at a time machine, but it's still faster than CP/M and an 8080a ;-) I've got PostGres running, (I'm an old Oracle DBA), have not done anything with it yet. Was going to use it to control an Ardunio and a digital VFO at some point.

    Volumio - Audio player

    Pi-top - Raspberry Pi Laptop

    They are great little computers for dedicated tasks.

    I tested my Pi B+ as a Linux file server in January and got everything running with SSH and Samba. Got it to map a network drive ( actually, a mapped folder and a bunch of subdirectories) on Windows 10. I then set up rsync to demonstrate copying files to a network drive with "only new and changed files and directories" for backups. Now I have a file server on my Linux Mint heavy duty workhorse tower machine in the shack/lab doing the same with 90 GB+ of ham radio files. I no longer have to keep local files on multiple computers (two towers and 2 laptops) and the associated headaches on file versions not being the same. Running great for 2-1/2 months.

    I have a 3 B+ for experimenting, and a Zero and ZeroW. The ZeroW is being developed for a network time protocol clock with LCD displays for local and UTC for the shack. I'll eventually replace the big tower server with a 2GB Pi 4 to take advantage of USB3 for the storage drive and the much lower AC power requirements.

    Lost my Pi a while ago. Ran an update and it booted fine. Tried a few days later and it seemed to be "hung" so rebooted and lost network access. It's a headless unit and I have no monitor or keyboard to connect, so will have to wait for virus restrictions to end before taking it to a friend for troubleshooting.
