I've mentioned this on many occasions but I do like the idea of an extended dev lunchbox. If (when, really) I find my spare LCD, I can hook it up to the Pi3, a decent (probably home-built) battery pack with external power/charge option, prototyping area (breadboard) and an integrated PSU delivering clean, regulated 3.3V / 5V / 9V / 12V and variable output.
That way I can run the Pi3, power any projects and program my Arduino Uno / Trinket etc.
My old (unused) briefcase is a cracking size for it (and it's really tough) but it weights a ton empty, maybe a different case would be a better choice.
December has another interesting lineup to choose from.
A possible category that comes to mind is a Christmas decoration or any other special event electronic decoration. Maybe a topic for a future Project14...
On another note - Dudley threads this long that will have periodic additions should be listed in reverse chronological order so the latest comments appear at the beginning - avoiding having to scroll through the whole sequence to find where you last caught up.
Jack, maybe this universal question can be solved with a little postilla to the topic: learn by yourself making machines wasting their time.
I mean, the user learn as just for the reason that while learning, designing and making he remain - hopefully - alive he is not wasting his time. Then the result is a time-wasting machine that do nothing else than doing itself. But - based on this consideration we should introduce another important branch of philosophy that can be helpful to us solving this complex teorema: physics (that together math is another branch of the philosophy).
A machine that do nothing at the end of a cycle than consuming energy, no matter what form, is just an isoentropic engine if we exclude the power itself. And we can as we consider the power supply as an external non-influent element like the ground sound of the universe; the reason is that power supply will be present anyway in both a isoentropic machine or a common machine that do something to the external (i.e. is it not a closed system). Here I call to the bar Mr Carnot that can easily explain us what happens in a closed system.
balearicdynamics Enrico gets us into an interesting philosophical realm, and poses the question, "what constitutes waste". If it is not done properly, then the act of wasting time can be considered, by some, productive. So, it is not really a waste of time? Also, the activity of creating a true time waster has technical considerations of analysis and design, which exercises the limits of systems, and again fails as a true waste of time. Last, if a secondary device is employed to act as a time "waster", then who's time is it wasting, the user, or the device?
IMHO as a matter of fact you are both right and wrong Most depends on the complexity of the time wasting machine. It is true that this kind of projects opens a wider scenario as there is not a precise topic but just the machine behavior.
Now, days more number of deaths occurred in the drainage & unused wells! even some diseases spreading because of the waste garbage. i thought to find the solution for this problem.
In current scenario per month almost 10 people are died during drainage and unused well cleaning. Because of forming dangerous gases in those areas.
I have researched something about the dangerous gases in those places(Drainage & Unused Well).Finally i found what are all the gases are forming in those places and how much the percentage of gases in those places.
Carbon monoxide(CO), Hydrogen Sulphide (H2S), Methane (CH4). These 3 gases are forming in those places its causes more problem for living things. In case of human beings affected by these gases . it will leads to death.
So i have an one idea to solve this problem in society , To make a device to identify what are all the gases in those places and find how much the percentage of gases are present like this. If we are going to use this device we can check the air condition if the oxygen is present or not. we can avoid the those critical condition.
"Don't take action after everything happened ! Make action before "
Really great idea for kitchen gadgets. An IoT Coffee Machine would be an amazing project. I have a Keurig K575. While it is a marvel of coffee technology, I really need an Alexa-Compatible Smart Coffee/Tea/Adult Beverage Machine.
There perhaps needs to be a step-change in packaging first for this to start to work well. Packaging needs to have some sort of low cost RFID equivalent of the bar code (which contains best before information along with the product id).
There is then still the issue of how to keep track of items which aren't used completely in one go.
