Oh definitely, especially if it already has a pivoting mechanism, that was the hardest part! Only thing to be careful of is making sure the wires don't snag when it rotates, but an owl would be awesome. :)

Thanks!

Ah it's just for indoors, perched above my chamber door mostly. Having said that it did get pretty soaked while I was photographing it and seems to have survived!

Fair comment, I was following via the MotionEyeOS wiki so failed to make that distinction, first time I've used the application version!

Hey thanks that's a good point, I'll definitely give that a go, it's certainly a bit pricey! I'm hoping soon I'll get a 3d printer to help with custom small fittings, but I'm sure I'll still need mouldable glue.

Thanks!

Thank you - I came upon the lens/display combination by accident while messing about with magnifiers, and the rest of the build kind of grew around that!

Aha that's a 100% fair point! The truth is, originally I planned to include a large LiPo battery (you can see it in the video), and to make room for it I had to remove one of the screw posts, it would have been fine with just one original screw/post and the clips - but I chopped out the wrong post, so ended up losing both. Those bolts weren't ideal but were the only ones I had that were long enough to go through the case - next time I have it apart (which is regularly) I might replace them, now that the DIY shop is open again! :)

Thank you, that's great!

You're right, handling it, it feels like a bulky old cordless house phone!

Thanks, I kicked myself so hard over that - failures are definitely part of the process though!

Hi, thanks! - it's as simple as having an old Pi handy but not an arduino, the LED control would have been easier too but the personal challenge was all about making use of what I had and not ordering anything new.

I have one in pieces as I type - a few more challenges with the space but definitely giving it a go :)

Thanks! It's certainly cleaner than my workbench, lots of destroyed cassettes and plastic everywhere :)

Thanks! Wow loom bands that brings back memories!

Ah no I'd never do that! I look out for broken stuff especially that would otherwise go to waste. It's also much cheaper to buy! :)

They're really useful things, bit delicate but save a lot of space - I think mine was in a "Pi Zero Essentials" bundle but if you search "Pi Zero USB Shim" you can get them singly, Amazon in the UK do them https://www.amazon.co.uk/ThePiHut-USB-microUSB-Converter-Shim/dp/B01BVEFHC4 so hopefully they're cheaply available everywhere!

Thanks!

Thanks! Got my first walkman in 84 for a school trip so very fond memories :)

Thanks that's great! They went down really well - attempting to make something similar this year but in chocolate, bit messier but we get to eat all the mistakes :)

That's great thanks! I do really love it and am about to start on another multi-station one using the same method for another room - the Volume Up button is connected between GPIO5 (Physical Pin 29) and GND, and Volume Down is connected between GPIO7 (Physical Pin 26) and GND. You could use different pins if you like as long as they're not already being used, e.g. by the audio HAT. Good luck with your build!

Thanks - it was a space thing, I needed the Pi to lie flat in the case and the original speaker was just too wide!

Thanks!

It's a weird one, if you dangle the radio from its cord the display and speaker look "right", but if it's on a surface the display is upside down! I really wanted to reverse the faceplate thinking it'd come off but it's really just kind of a foil-thin veneer stuck onto the plastic, I knew I'd destroy it if I tried to take it off!

Too long really - I should've used a more stripped-down version of Raspbian, just timed it for curiosity and it takes 1m15s - about the same time as it takes my water to heat up conveniently!

Ah yes that's a much better quality product! An actual circuit board and microswitches inside instead of wires and screws. I've definitely played on one of those at a friend's house way back in dinosaur times, something about those grippy sides jogs a strong memory - thanks for that!

Thanks!

The contacts must've been pretty brittle as well as springy! We used to bend them a bit to make the controls more sensitive, but never looked back when the microswitch controllers came out, I remember my Konix Speedking being a serious upgrade for games like Yie Arr Kung Fu, and DTD of course!

Yip it's the same e-ink technology, just with three colours rather than just black & white. It doesn't refresh as fast as the kindle when in 3 colour mode but I saw the other day if you run it in B&W it's much faster. :)

Hey that's great! Good call on the 3.5mm soldering, I was never 100% happy with that thing sticking out but didn't want to risk inflicting my soldering on the original board and killing it. Power supply looks good too, really neat - I love that it's the same model!

Hi Kenneth and thanks very much for sharing the useful links and your code experiences! I had similar head-scratching with PyUserInput at first but tracked it down to how I'd installed it, if I remember rightly I first installed it with "pip install PyUserInput" then got those "No Module Named ..." errors, then when I instead used "pip3 install PyUserInput" it was fine all the way, I think it's to do with the version of Python that pip and the Pi use as default. Hope that helps!

I'm glad you're making progress there! I remember having problems like that with it when I was getting it to run on boot from the autostart file, turned out it would only run *without* the sudo before the python3, which sounds similar to your SSH problems. Good luck with the rest of it!

Good question - I used a lot of bits I already had, to use exactly the same things it'd probably be around £60, but I splurged on a specific speaker for the case and used the pHAT Beat, really for a basic version you just need a Pi, a webcam, button and a battery speaker so could be as little as £40-45 :)

That was an interesting test - I left it ringing until it timed out, about a minute, and the "knock knock" preview video didn't show through at all. Wondering if it would be any different with an integrated Pi camera rather than a USB webcam, will give it a try once I've got the "one box" version working.

I'll give it a go later this afternoon and reply back - curious myself now!

I think technically if you have "Knock Knock" turned on in the Duo settings then it's set to show the video as a preview, but in reality on the Pi it makes the connection first and starts ringing then shows video as soon as it can, which takes a second or two - I imagine it would show the preview if it was left ringing long enough?

I think so, yes, you'd probably need to install the Python module fswebcam but then it'd be straightforward to take a pic, just an extra few lines of code to do the capture after the button is pushed. Bit more info at https://www.raspberrypi.org/documentation/usage/webcams/ - what I'm not sure about is whether access to the webcam is "locked" by Google Duo (because the webcam is already selected in the Audio & Video sources) - in this case the fswebcam module might not be able to do the capture.

Thank you!

Thanks! I love that it works pretty simply with fairly standard bits 'n pieces, good luck with your build!
