LOL this is funny! I could see myself grossing some people out with this. It would make a hilarious April Fool's joke as well. Hehe.
Remote-control nature photography
I was hoping that it implied the information was out there, but you're probably right - it'll be proprietary :-( I wonder if they have access to the info from the manufacturers or if they reverse engineered a bunch of remotes like you did?
lol! love this

Control any remote from a Raspberry Pi (and Amazon Echo!)
Well yes, it's my supper rather than breakfast!
I bet you're not going to approve of this, but I just love granola when it's served in a mixture that's 2/3rds plain lowfat yoghurt and 1/3rd sugar-free Cool Whip :-) Tasty!
I would recommend projecting the image on to the cake for the painting step.
Norwegian Brown Cheese
Wow - I had no idea that there was no sugar added to Gjetost - I love this kind of cheese but my wife won't let me buy it because it's so sweet (she does a good job of keeping my diabetes in check!) - but we'd always assumed the cheese was made with added sugar. Never realised it was just lactose from boiled-down milk. (Which I think is not so dangerous to diabetics, at least that's the excuse I use when I buy Indian sweets like Kaju Katli which don't have sucrose either :-) )
PS At least in South Texas, this is sold in the local supermarkets such as HEB.This brand specifically: https://www.amazon.com/Ski-Queen-Gjetost-2-pack/dp/B00E8HZDCQ/ (cheaper in the stores than that Amazon seller)
I have a vague recollection of making something that was just like the caramel in a mars bar, and although I forget how exactly I did it, I think it may have been as simple as a can of sweetened condensed milk in a microwave. (Not in the actual can of course!) Have you experimented with microwaving it instead of boiling it at all?
My wife has a "never fail" fudge recipe that is based on jars of Marshmallow. I may record her making it for Christmas so we can see which really is the easiest ever :-)
maybe make a bed of peltier chips for surface cooling without a breeze?
Thanks, I'll look into ha-bridge. ( http://bwssystems.com/ , https://github.com/bwssytems/ha-bridge ) Also I found a device called 'Hook' yesterday (which I've already ordered!) that looks better than what I implemented at the same cost ($50) - they clone the RF signals rather than using relays: http://www.hooksmarthome.com/
you might want to have a look at ha-bridge by Bwssystems. can create multiple devices through a nice Web GUI. much easer to use than fauxmo
with haggis and tatties!
In case anyone expands a system like this, that was the wrong board above - this is what I should have linked to: http://www.ebay.com/itm/262136732889
@gtoal: thanks for the fauxmo update link :)I gonna try to get my setup working within the next days
With a little effort you can have the pi broadcast its IP address (either DNS or with Bonjour) or you can configure it to always be given the same address by your router. Scanning for the IP each time is a bit awkward.
Using an android is a very cost-effective way of getting a reasonable sized screen on cheap. The downside is that VNC isn't fast enough for real-time video or even most reasonably fast video games. But if you're just using it as a semi-static display (eg for weather, or as a soft panel for an in-home lights controller etc) then it's a good solution. I've seen cheap Chinese androids down at the $30 mark, and even a relatively good machine like a Kindle Fire is sometimes on sale cheaper than the official Pi LCD screen.
Actually '9V' rechargables are usually really 7.4V Lipos, and when you take into account the .6V drop from a typical buck converter/regulator, you're in the right ballpark for running a 5V system such as a Raspberry Pi.
I upgraded my system a couple of weeks ago to support all 5 devices - the version of fauxmo.py at https://github.com/makermusings/fauxmo works fine with multiple devices.

Recycle christmas card as digital recorder module
I'm currently working on using this to add commands like "alexa, turn on bbc america". It's complex. First I send a 'Wake On Lan' packet to my LG Bluray player (since my TV doesn't have WOL itself, and it doesn't wake up for my DirectTV box, but it will wake up for the HDMI CEC signal from the bluray :-( ). Then I ask the LG TV to change input to the DirectTV box, then I ask the DirectTV box to select the appropriate channel. All of these are doable over local network IP, but getting them all to play together is hard work! I'm not quite there yet. (Blueray and DirectTV are working, but I'm having problems controlling the 2011 model of LG TV) Icing on the cake, I'm getting the festival speech synth to work with a bluetooth speaker so I can get the Echo to report what is playing...
You have to have some way of controlling your device from a computer. For instance, a shell script that access GPIO pins, or sends a command to an IP-enabled device using some device-specific protocol. Then you modify the python code that this project refers to, so that it invokes that shell script on the web server where it is running. (See my remote control project below for an actual example)
fyi there's a newer version of fauxmo.py at https://raw.githubusercontent.com/makermusings/fauxmo/master/fauxmo.py which supports multiple devices. I've tried it - it works. It fetches a web cgi to cause the action to be initiated. You have to supply that cgi script yourself.
Perfect-fit bath plug (Made with Oogoo)
If you can wait a bit, I've recently bought a Pi Zero with a camera cable, and intend to re-do the retrocam using that instead - it should be much easier to fit in the camera body. I have a second camera ready, and I'll photograph the process more carefully next time. The photos were all right but getting the exposure right automatically was tricky - if it was well exposed indoors, it would be washed-out in bright sunshine. I now have a lux meter sensor that I want to add in the next one to use as a built-in light-meter. It would be possible to use the camera as a light meter but there would be a noticable delay between pressing the button and the picture being taken which I didn't want.
I would like to try this, but I am not very electronics savy. Also, do you have any pics to post that you have taken with the modded TLR?
Retro Pi Cam
Don't insects get in through the holes in the top? I live in a hot climate (south texas) and would be inclined to do this rather than use an electric dehydrator but I guarantee that drosophila, flies, and ants would be all over it if there was the slightest entrance for them to use.

The Frankenputer! (Raspberry Pi Laptop)
I'm retired now, but when I was working we had many displays that were rotatable, and they all sensed when the display was rotated and the OS (Windows in our case) adjusted and rotated the display automatically to match, I think you've assumed that this doesn't happen because you haven't seen a display that behaves like this? It *is* fully automatic. Unfortunately since I no longer have access to that hardware I can't look at the specific models to give you a reference however a quick Google search finds many: http://www.pcworld.com/article/2042888/review-three-widescreen-hd-monitors-that-pivot-from-portrait-to-landscape.html Both VGA and HDMI connectors support protocols nowadays to announce the orientation to the OS.
Rrotatable displays signal to the OS when they are rotated, and the screen driver adjusts automatically. Did you do this because you don't have the right drivers, or because the monitor you're using doesn't have rotation support? Instead of adding an external interface to communicate with the PC, wouldn't it be cleaner to modify the VGA or HDMI interface to report the rotation like a display that has built-in rotation support would do, so you can use the automatic rotation support in the OS? (I'm not criticising the project - it's a nice piece of work - I'm just interested in how you came to the design decisions that you did)
Actually I haven't yet added a second device so I can't advise yet - it's something I plan to do but with other commitments it may be about a month or so before I can work on it. You'll probably have worked it out yourself before I do! One (rather poor) solution that springs to mind - if there isn't a more sensible one available - would be to attach multiple IP addresses to your Pi and determine which device to enable based on which IP address it was accessed under. Whether that could be done by one listener on all IPs or whether you would need multiple copies of the listener, I'm not sure.Thanks for the heads-up on relay bounce - I guess it will be an issue for remotes where the key toggles something - with this remote it just reissued the same command, and two 'on's are still just an 'on'. The remote has separate on and off buttons.By the way have you seen this? https://hackaday.io/project/6820-amazon-echo-voice-command-automation
Ordered an echo on prime day. Had a raspberry pi sitting around. I just got this working. Original idea was to mimic button presses on a scene remote control for my home automation system. Currently using to start my car. Using transistors to switch instead of relays so I don't have to worry about relay bounce. Want to attach to the scene controller now. I have multiple programs setup to run the different goip pins for each scene controller button, and they work from command line. How do I add more devices to call the scene programs individually from echo. Can't figure that part out. Was able to change the device name and add extra devices to run the same program.
