Raspberry π

And I have been buggering about with PIRs (though on an arduino actually)

I've got to redo one of the gnd pins, that'll be a 2022 job I guess!

Anything useful/ exciting?

I ordered PIR, potentiometers and buzzers last night. PiHut is dangerous though, at one point my basket was £120 then after some self reflection about wants vs needs I got it down to £17

Any suggestions for a raspberry pi camera? Planning to use as part of an outdoor security camera setup so will need IR for nighttime. Range of about 0-5 metres so may also need to be wide angle I guess. Weatherproofing or an easily available weatherproof case would be a bonus.

Naturebytes?

Cheers but I'm not sure how obvious that would look attached to the side of a house, it doesn't seem to give dimensions anywhere but I suspect it is largish as it fits a battery pack too.

It's about 18x14x10 cm.

It would look fairly obvious but I always thought that was the main point of a security camera? The recording is frequently of no use after the event and they aren't often monitored.

Apparently this fake camera has enough space inside for a Pi Zero and camera but it might require some effort to mount the camera - https://www.amazon.co.uk/WALI-Surveillance-Security-Outdoor-Warning/dp/B06Y4FJD33/

PIR is up and running, but not as expected.

I thought it'd work like an alarm trigger but there's a huge delay from running the code and moving my hand in front of it to it triggering. Then another huge delay whilst it has a nap before I can trigger it again. #triggered.

I've set delay to minimum and sensitivity to maximum...

This is the PIR I'm using.

Any ideas what I might be doing wrong?

For Halloween I want it to be an instant trigger to drive this with flashing red eyes for visitors to the door:

Update: I wrote a crude logfile into the script to capture time between events. There looks to be 210s between PIR activations despite me being right next to it and others passing by as they move around the kitchen, with delay set to lowest and max sensitivity.

Last update: I left it running whilst we were all out the room for a good while. As soon as I walked it in triggered, then took 210s to trigger again. Looks like it isn't resetting- could that be an issue in the code?

A bit of Google helped me find a different code to do the same which when tinkered means the PIR triggers often. I think it's to do with a "Pin pull down" something or other that the micropython book included in it's code and is omitted in the new one.

This should add 1% more joy to trick 'n treat night this year...

I have a small boat. I am going to use the PIR to dissuade stoned tourists from using it as a bed for the night

i used to have two of these on my mission workshop fakenger bag but the pins on both broke far too easily and were lost.

Trigger a claxon yeah?

Yes it all looks a bit fragile. I need to work out what housing, might embed it in a pumpkin with the pir on top.

Hmm...

I'm working on a processing project on raspberry pi. I'm trying to use the gl video library but cannot get it to work. I've followed the instructions but get the error "failed to load pluggin /file location cannot open shared file: no file or directory" . It's there and the user has access and you can find it using command line.

Any ideas on what to Google?

Maybe you've installed the wrong version of the library? https://raspberrypi.stackexchange.com/a/108237

I tried lots of combinations of versions but never got anything to work.

Eventually used the standard video library, but on realising I couldn't easily use a neopixel and processing at the same time swapped to python.

It's for an interactive nft artwork project controlled through a window and projected onto 7 screens on the side of a building.

I might try doing this so I can boot my 400 into a zwifting machine or whatever zwiftingers call it.

Fun!

Would anyone be interested in a pi 2b + breadboard/wires/ir sensors? I bought them a few years ago planning on making a IOT TV remote, but I quickly gave up.

I want to make a p2p network using RPis, preferably using the cheap £10 Pi Zero Ws as web hosts. Download a pre-made OS image, load it in, forward a port on your router and it automatically connects to the p2p network. The network would be a community with a chat/forum, personal profile pages etc.

I like the idea of being able to use cheap devices to build a grassroots type thing that doesn't rely on Google/AWS etc.

Would even have its own "free domain" type identity system, and maybe be accessible via a web proxy for people who aren't tech savvy.

Pi Zero 2 launches today, apparently has a bit more oomph . Going to get one to see if it can process my timelapse videos any better than the original zero did.

Might try the zwift project posted ^^^^ on it too 😂

Fwiw the zero2 more than matches the 3b+ for the timelapse stuff. 5 mins of 300 pictures takes 5 mins to process to timelapse then tweet
