    It seems like I was too large to go through the pelvis, we would have both died when I was born. Note that a c-section is not the most modern thing either

    You're welcome. I have quite the bunch of Raspberry Pi in operation.
    I'll go chronologically.

    • Pi1B running the AcceleROB project, the O.G. Raspberry Shake initiative from the Royal Observatory of Belgium, which awaits for the next big earthquake expected to come soon so they can map the the underground geologic characteristics of the country with a network of ca 100 raspberry Pi.
    • A pair of Pi3A+ running Octoprint and Klipper, each managing a 3D Printer
    • Pi0W running Octoprint on a 3rd 3D printer - it takes a few minutes to boot and catch its breath
    • Pi3B+ running my home automation based on Node Red and Mosquitto, backed with a 'Pi UPS' power supply that provides about 8 hours of autonomy
    • Pi3A+ running my ADSB feed : dump1090, FlightRadar24, Flight Aware, ADSB exchange
    • Pi3B+ running Cloudflared ingress tunnels, HA Proxy, lighttpd as a web server as well as Node Red to serve my personal weather station data. It also runs Pihole with Cloudflared DNS of HTTPS tunnel, with GravitySync, a PiVPN (Wireguard) instance, SSH opened to the internet (hardened), fail2ban
    • Pi4B 4GB running Logitech Media Server with my music library, an apt-cacher-ng instance, PiHole with Cloudflared DoH, GravitySync, PiVPN, hardened SSH, fail2ban
    • Pi0W connected to my weather station receiver, running a custom python script to poll the data and send it to the home automation instance of Node Red, and a bash script that uses NC to store the Unihedron SQM-LE sky monitoring (measure of the darkness of the sky for amateur astronomy purposes)
    • Pi02W as a central syslog (not used)
    • Pi4B 8GB that was used as a desktop computer (not used anymore)

    The home lab part of it is all together in a box, all attached on a DIN rail, with a 60W 10 ports Anker USB power supply and a 8 port gigabit switch stripped naked to save space. All the DIN brackets were of course 3D printed.

    It consumes 16 watts when idle, I'm really contemplating moving to a Proxmox setup on a N100-based mini PC.

    I did start with a pair of Pi Zero W years ago, then moved to a Pi4 and a Pi3, both running Cloudflared for DNS over HTTPS upstream.
    From my various tests with DNSBench, the ethernet connection does not add any significant performance advantage against WiFi. The switch from the Pi Zero W to beefier Pis was to make sure I use a recent Cloudflared daemon (not compatible anymore with Pi1 / Pi zero W architecture), as well as save a few watts as the Pi4 and Pi3 were already providing other services anyway.

And I often place orders on amz NL/DE/UK/BE instead of just FR where I'm 'Prime', shipping if free above 25€ or something similar.

    I've been feeding ADSB with a Rapberry Pi for quite a while now.
    Starting with an off the shelf SDR was fun, but getting a dedicated receiver, antenna and cavity filter really upped my game.

    My current hardware :

    • Raspberry Pi 3A+ with an official Raspberry 5.1V 3A power supply (USB-C with micro USB converter). Having a weak power supply gave me "unstable clock" error messages that rendered MLAT very unreliable. I've also fixed the CPU clock to 1GHz permanently in order to tackle any clock issue. There's a Pimoroni fan shim controlled by the gpio-fan dtoverlay module. The CPU only reaches around 40% use when dealing with 1400 frames per second.
    • FlightAware Pro Stick Plus, a dedicated SDR with amplifier and 1090 filter built-in (~40€)
    • 1090 MHz cavity filter from Sysmocom, as a cell tower is in sight from my antenna (~50€)
    • 55cm +5dBi ADSB antenna from Jetvision (~80€).

    It's currently feeding to FlightRadar24, FlightAware and ADSBExchange. I've also been sharing to the Opensky Network for a while, but all combined it was using a bit of bandwidth and my DSL is not unlimited.

    I've had an issue with FlightRadar24 last year (it's the base of my raspberry pi image) due to a bad setup of Flightaware that fed MLAT data back to dump1090. That gave unexpected data from FR24 point of view and my account was automatically blocked. Their support is excellent and after a few days of back and forth we understood what was going on, adapted my dump1090 settings and all went back to normal.

    EDIT : It sees between 3700 and 4000 aircrafts per day.

    I'm actually usually quite lucky, although I never enter much contests. As a kid we won a drawing contest with the whole family (cousins and all...) and won some Lego, then as a teen I won a CD-Rom with english lessons, as an adult got my girlfriend and I both chosen from a literal drawing of the names from a hat to visit the top of a windmill. After that tickets to Disneyland, and a bit later a week-end for 4 people to a French amusement park from a radio raffle, including a nice hotel and the train, all inclusive. I propably won 90% of the time, but I'm not a player, it's only when I feel like it.

    I recently inherited my dad's 1944 Ford GPW, it's been in the family since my grandfather bought it in '71 or '73, he was really in an things WW2. Then my dad was really involved in a local club at the end of the 70s, driving their jeeps to Normandy once in a while, and so on.
    It's in top condition at my parents's, I'll try to take it for a spin this summer. I haven't driven for about 20 years, and it probably hasn't run for 15 years, since the engine was refurbished.

    That looks like a fun project !
    Cloud cover will make the detection of dawn/dusk quite tricky.
    From my experience with home automation, there is quite a luminosity range due to bad weather.
    I would rather try to find the astronomical noon by detecting the maximum luminosity of the day, and maybe limit the sensor view to due south where the sun is expected. And even then, it would be probably be good to limit the measurement to an hour around the expected noon, then build a moving average day after day around that.

    It's been unusually warm this month in Belgium, I would say summer is a month early compared to the previous years (that were way warmer than in my youth).
    Very dry too, which is not what we expect in summer.
    My home weather station is an older model I've been using for 15 years now : the WH1080 built by Fine Offset. At the time I got in touch with them and got the datasheet and memory map. So I'm attached to that model as it's my only foray in connecting directly to a USB device with my own software (at the time, running on my linux TV box then my NAS). Now it's running a modded version of this projet on a Raspberry Pi, that feeds its raw data as a single string to Node Red.
    Node Red integrates it in my home automation, and sends it to Weather Underground. It's also available as a public web page that the local astronomy guys use as I've included the SQM-LE measurements as well (it measures the darkness off the sky).

    I knew them since forever but didn't realize they were so influencial.
    I actually went see them live yesterday in Brussels. I was impressed by Russel's voice range and power nearly identical to what it was on their first album some 50 years ago.
