There was a guy that decided to make a toaster from scratch [0]. Literally from scratch: as in, mining and refining ore, etc. It was a bit of a stunt [1], but it definitely highlighted the advantage of scale and industry we typically take for granted. [0] - http://www.thetoasterproject.org/page2.htm [1] - https://gizmodo.com/one-mans-nearly-impossible-quest-to-make...

I get the point he's trying to make, but really, if I'm alone in the woods and wanted to toast some bread, I'm pretty sure I could just hold it over a fire for a few minutes.

From the toaster projects author's website [1]

> So, firstly, yes, I realise toasting bread over a fire would’ve been a lot easier. But was a piece of toast (or designing a better toaster) really the point of this project?

What problems are you facing on the pi? The USB power to me is a big win. I already have a ton of cables sitting around.

My biggest problem is more of a mechanical issue, the darn micro USB connector is difficult to align and after a while of plugging in and out(especially due to being difficult to quickly see if it's right side up) it becomes loose. As far as power itself, I have only run into catastrophic problems when attempting to use a hand held solar powered battery backup bank and when I tried to use a car cigarette lighter USB…

I actually bought some small micro usb power dongles with switches on them. So you only plug it into the pi once, then plug the dongle into the actual power source. Also means you can turn it on/off without being forced to pull the plug.

Most phone chargers now are 1.5-2A standard... My first pi (a B, not a B+, gen 1) it was pretty common for phone chargers to be 1A. I still remember over clocking it no problem. Just looking at the 3 chargers sitting next to me they are 3A (phone), 1A (tablet) and 1.6A (IDK, probably a phone). I've had all these for several years (you can probably guess the order). I think I'd be hard pressed to find one that was For…

I never said anything about a phone charger. Are you confused who you are replying to?

I'm replying to you because I don't know why you're bringing up USB power requirements as an issue.

I feel that again misses the point. Sure, it's perfectly possible for a resourceful and knowledgable human to hand-engineer various tools from the environment. But to make something very much like an ordinary pencil made of wood, graphite, rubber, metal, and paint would be a monumental task, far beyond the cost of a pencil in our established society. The fact is that globalization and industrialization has democratiz…

I kinda see, the value is in efficiency of delegation but IMO there are drawbacks that this 'efficient' perspective hides, namely people believe you can't do anything without the market.

Yep because history has proven that believe to be correct.

Just bought one. Been a while since I played with embedded systems (or ML for that matter) :) Anyone have any cool ideas for how to make this little toy useful?

- Smart camera for a doorbell? Train it to detect a person or a package? - Smart camera to detect your posture, and message you when you slouch for more than 3 minutes? - buy tons and tons of sensors and just hook them all up to see if you can detect anything at all? VOC sensors, heat, light, noise, see if any of these things can diagnose comfort, sleep, health issues in your life?

for all of that you can use $30 raspberry pi... for some of that you can use $5 raspberry zero and get wifi on board

Unfortunately for me a lot of times that requires digging behind a piece of furniture :)
