I live in a condo/townhouse situation where the (underground) basement, second and third floors are mine. I mention underground because it's not one of those halfway things, there's a regular first/ground floor.
In any case, I have the shake in the basement on the bare concrete floor and when there's minimal noise late at night I can see a very clear signal if I thrum/drum(?) (https://images.app.goo.gl/i8cMPxef7kiQRFwh9) my fingers on my desk on the third floor.
I'm reading this and wondering if a small cooling fan would destroy the potential usefulness of the device, and, if I could passively cool a Pi and this hat, whether the secondary problem of the regular coal-train service with 78 wagons, that runs the other side of the valley (say 1.2km away) every 3-4 hours, would either a) make it pointless or b) register.
I think the train would clearly register and it would not really be pointless. If the coal train passes every 3 to 4 hours and takes a few minutes to pass you’d register a total of perhaps 30 minutes, the rest would be cleaner. Best place to put this device in a basement though
Thanks - that has re-piqued my interest then. I'm on a rural property, no basement, but lots of undisturbed land with few people around. Bountiful night time and crepuscular animals however, that may interrupt the relative (and presumably very delicate) tranquillity of such devices.
Reading TFA it sounds like readings are often rejected by authoritative sources, but are still locally extremely useful.
I've got few of the model 4, though most of my Pis are earlier models. Earlier models I rarely had a fan involved, but the first two model 4s I used, I put on a big metal heatsink that included two fans. For my purposes the fans seem to be fine to be disabled, and the device doesn't throttle back due to thermal overload.
However - the heatsink takes up a lot of space, and probably can not be used with this kind of hat, so I'd have to look at a less passive cooling option I think.
Also, where I'd be deploying something like this would be in a part of Australia where through summer ambient air temperature can get around 50C, and if it's in a shed or covered area, perhaps higher. I haven't had a Pi4 running here through a summer yet, so have no idea how that's going to play out. In about two months from now I'll have a better idea.
The Pi 4 does, but it looks like you can pair the Shake seismometer hats with the Pi Zero W, those run fine with passive cooling (especially bolted to a concrete slab in the basement, I'd say).
