My current roadblock is getting a relatively high resolution rather wide aspect ratio screen. Hard to find, it seems.
I’ve also convinced the company to buy 8 3B. Each of those is connected to a 1080p display through HDMI and each one of them boots raspian with chromium-browser in kiosk mode into one specific Grafana panel or playlist. I control what URL each of them boots into from Saltstack states.
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…

I have several * Pie-hole and runs Nagios to collect information about things going on inside the network. * One running a PiDP-11 (pdp 11/70 emulator) as well as providing MOP service to boot my DEC terminal multiplexor (it provides the boot image when the mux comes up) * One is a stratum-1 time server using an Adafruit GPS module with PPS output. This because I got tired of both the reflection attacks and trying to…
> * One sits on my electronics workbench and runs OpenOCD and allows BlackMagic Probes to export GDB as a service over the network. That lets me debug from anywhere without burning a USB port or adding additional software. This sounds cool and interesting. Can you elaborate on the setup and some of the ways you've used it?
From anywhere on the network when you start arm-none-eabi-gdb, you can type
target extended-remote debug:3333
Since the Black Magic Probe has its own gdb server you wrap it with nc(1) so on the Pi you run
nc -kl 1234 /dev/ttyACM0
Of course I've got that particular RasPi mapped to the host name 'debug' for that reason, the one that runs the waveforms software is named 'instruments' :-)
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…
I discovered that my 17-month old son loves to mess with stereo controls. So I bought a few rotary encoders and neo-pixel rings - build a wooden enclosure with a plastic faceplate, and wrote some code to generate fancy light and audio effects when he turns/clicks the knobs. He loves it.
