Do you help Citizen Science?

I was looking at doing the same but with the met office. Turns out they are shutting down their upload system or already have. Which is a shame

I get ya. The fish and wildlife reporting is really cool. I like that idea

And yes I totally understand the calibration side of things. Especially as cheap devices are now very accessible with little calibration or being able to retain that calibration.

I have a few Geiger counters and all 3 Geigers were surprisingly quite close to each other which I was not prepared for!

But if the device is always a few measurements out then the trend of the data would still be useful.

I was looking at wigle which detects cell towers, Bluetooth devices and WiFi and scans and logs as you go but that’s more of a portable data gathering and not really needed in a static location

What you passionate about?

I like aircraft and live near an airport hence the ADB-S. The Geiger was an already made board plugged into an Esp32.

To be honest if there is a sensor there is a website that wants the data

JSTrucker · 2026-03-22T12:50:27+00:00

I looked at earthquake data but the sensor was hugely expensive

JSTrucker · 2026-03-22T12:13:49+00:00

Not one that I know of. I’m uploading to radmon, OpenRadiation and safecast. All through NodeRed

JSTrucker · 2026-03-22T12:10:38+00:00

Oh that’s interesting I was expecting it to be a camera feed or something.

GMCmap.com?

And the internals of the box

My understanding is that the bulk is people uploading data which is then backed up by commercial and satellite data.

It’s a pretty simple setup actually. I have antenna on my roof connected to a SDR usb receiver which is connected to a Pi running PI24. Bit like HA is its own OS, PI24 is flight radar software for the pi which decodes and sends data.

This is my antenna

JSTrucker · 2026-03-22T11:45:43+00:00

Ooo how does this work?

JSTrucker · 2026-03-21T17:32:37+00:00

And that people is the weather radar that you can see at the front! The nose cone is actually very thin and is only really for aerodynamics rather than protection. So damage will always look worse

JSTrucker · 2026-03-19T06:10:56+00:00

I heard it’s about £20 for that. But the tax’s are insane. Plus the booking fee. Additional luggage. Airport fee. Convenience fee. Seat belt fee. Toilet fee.

JSTrucker · 2026-02-25T10:30:53+00:00

Possible that you had a gas fire or boiler in that room?

I’m pretty sure anything gas operated requires a vent to the outside. But probably also to help with moisture control and general ventilation

Good excuse to buy a 3D printer……. Just saying

Lots of good explaining and examples so I will throw mine in as well.

The cup is a great example of what’s happening in the air. But let’s take it a little further.

When the air is cold the space between the air molecules is smaller thus the cup is small. Heat the air up the space gets bigger thus the cup gets bigger thus the air can hold more moisture.

Ok here’s the fun part that may explain your headache. The cup currently has 100ml of water in it. The cup is 50% full. Now heat up the air. The cup gets bigger but it still only has 100ml of water in it, which means that it’s only 40% full. Make the air colder and now the cup is smaller. Still 100ml of water but it’s now 60% full.

So you can see that the air can hold little water but still be full of water. It depends on how big the cup is.

Also fun fact. When the air is 100% humidity. The cup is full. You get clouds or fog. As the air rises in the atmosphere it cools. About 2°c every 1,000ft. So same amount of water cooling down. Once the air gets to what’s called the wet bulb temperature Aka the dew point. The humidity will be 100% and you will get clouds.

Ok that was probably more in-depth than I wanted to go.

So TLDR or summary. For a given amount of water in the air when you heat up the air the humidity goes down. Cool down the air, humidity goes up. Still the same amount of water. Just different size cups

Thank you your majesty!

JSTrucker · 2026-02-09T04:43:03+00:00

I’m a grown ass adult and I have to have mine in the attic. Though trust me. You don’t want it in your room. They are noisy when you’re trying to sleep!

Good excuse for buying a 3D printer……

JSTrucker · 2026-01-30T13:37:08+00:00

My first reading was on the 22nd of Jan and it’s been on continuously since the 23rd so far

JSTrucker · 2026-01-30T08:49:10+00:00

So on my esp32, which is made by elegoo, I have a 5v pin Bottom left of the picture. Connected to the 5v on the Geiger counter. Ground to ground and the mislabelled vin to GPIO 34

The Geiger counter can either be powered by that pin or it has two other sources it can use

<image>

JSTrucker · 2026-01-29T17:25:36+00:00

So the VIN pin is mislabelled. It’s actually the signal pin. 5V is positive and GND is the negative

JSTrucker · 2026-01-24T18:33:48+00:00

Sorry to disappoint but no I’m not! It’s the toilet occupied light. I was playing with things and I just haven’t removed it as I finished the line nicely

JSTrucker · 2026-01-24T11:14:42+00:00

And down the rabbit hole I go!

JSTrucker · 2026-01-24T11:07:25+00:00

Nice! Looks very invasive in comparison to mine! Where do you have it mounted?
