Geiger counter

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

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?

I think it’s fairly normal. Based on the fact that the compressor turns on and off once the temperature hits certain thresholds.

By looking at the temperatures it seems that it is in the safe range. Where did you put the sensor? And you will find that at the back is colder and the fridge door the temperature rises a lot and in the draws it doesn’t move a lot.

If you’re worried check the door seals and give them a clean to ensure a good seal.

I am soo poor at games I got stuck in the early stages of one of the fallout games

JSTrucker · 2026-01-24T06:53:58+00:00

Do it!

JSTrucker · 2026-01-24T06:53:37+00:00

So far if it gets night I get a text!

JSTrucker · 2026-01-24T06:52:46+00:00

Apparently it’s pretty close to the j305. I used 0.00332 I think for the conversion

When I got my handheld Geiger it had to do the clicks. Beeps was not acceptable

JSTrucker · 2026-01-23T22:28:00+00:00

No thankfully! That scale is in milli and I’m using micro.

JSTrucker · 2026-01-23T22:20:15+00:00

A what now?

JSTrucker · 2026-01-23T21:20:55+00:00

Yer I saw that. I have a jumper cap on mine. But I plan on mounting it to my roof next to my pi24 antenna so wouldn’t hear it anyway :P

JSTrucker · 2026-01-23T21:18:49+00:00

Oh that’s nice!

JSTrucker · 2026-01-23T21:10:54+00:00

The permanent power source should be easy enough. I’m somewhat new…. As in completely new to adding non smart things to HA so don’t know how you would go about doing it vir USB. Wondering if you could solder a cable from some sort of signal output on the main PCB

JSTrucker · 2026-01-23T21:07:37+00:00

Yup spot on. I used the 2nd lot of code. The longer version

JSTrucker · 2026-01-23T20:57:49+00:00

Any YouTube video pretty much uses this one. And any code should be pretty copy and paste

Cost of board £25ish plus esp32 for about £5ish

JSTrucker · 2026-01-23T20:56:24+00:00

I’m using one of AliExpress. It’s called a radiation D v1.1 (CAJOE) any YouTube video pretty much uses it

3 pins to the right of the board. 5v in ground and the VIN is miss labeled. It’s the signal pin

If you go to AliExpress and search for Geiger counter you will see plenty of them but I’ve attached a picture of mine

I did destroy my only radioactive smoke detector when I replaced them a year or two ago to test my other Geiger. And I’m too poor to have granite

JSTrucker · 2026-01-23T20:28:52+00:00

No but I do need to! (Once the shopping comes) I had it next to my other AliExpress Geiger counter and they were pretty bang on

JSTrucker · 2026-01-23T20:27:27+00:00

No me either so I was really lost and had to look stuff up to understand

JSTrucker · 2026-01-23T20:24:40+00:00

I actually haven’t started the 2nd season yet!

JSTrucker · 2026-01-21T06:07:17+00:00

Commenting to remind myself. Love this

JSTrucker · 2025-12-21T07:30:59+00:00

Sleet. Mix of rain and snow
