Just hooking up a graphing calculator to an actual potato battery would get you the same result it seems...

Not as long a battery life though.

This isn't meant to be a serious product, it's a hobby project. The why is because they wanted to see if they could.

Yeah, but you can at least eat the potato when it's out of power and fast reload a new one. Potato charges computer, then potato charges you. Circle of life.

thedirtydeetch t1_jc5nmed wrote

Not true. Once the potato is drained of ions, the Heinz reaction can not occur, so the nutrients don’t metabolize properly when you cook it. That’s why you don’t see deionized potatoes as an industry, because even the cows can’t be sustained off them.

mr78rpm t1_jc5zeu0 wrote

Sorry, not true.

Chemical reactions between the potato and the metal things you jam into the potato cause electrical energy to be made. If you ate the potato, you'd be eating the residue of these chemical reactions, which, by the way, are probably poisonous.

It's so weird how often people don't seem to understand that concept on these kinds of builds.


WontFixMySwypeErrors t1_jc7zv7f wrote

Now that it's proven, I'd love to see a usable one, even still as a hobby project.

Something like a non-backlit tft display, perhaps in vertical orientation for coding, would make things much more usable, and there's room in that case for many times more battery capacity.

A similar soc should still have enough grunt to run Linux and an IDE, and now you've got a decent dev box with the same or more runtime.


Somepotato t1_jcqqi2l wrote

It's weird tho there are substantially more energy efficient MCUs you could use that are easily accessible, and the keyboard likely takes a chunk of energy compared to what it could be


tomistruth t1_jc65y2d wrote

It's not the potato that actually runs the computer but the metal sticks you put into the potato. The potato just provides the water and salt to transfer the electrons.


3226 t1_jc6l9yl wrote

Yes! Thank you! It drives me barmy when people seem to think you're getting the power from the potato, rather than a copper and zinc strip reacting. It's just a salt bridge. It's not the source of the energy. +

reMarkable 2 EInk tablet with keyboard folio. Definitely not very long battery life but quite long at least. And definitely not update free. But definitely task focused and distraction free.


GigaPuddi t1_jc67xy1 wrote

I have the original reMarkable bought used because I'm a cheap bastard and even that one is great. I work in sales (fenestration) and it makes keeping track of things so much simpler. Being able to copy and past scrawled notes makes keeping on the fly things organized so much easier.

I also use it for Dungeons and Dragons and it is invaluable for keeping my character's shit organized and updated.

I've considered upgrading to the second but I can't quite justify the expense.

I bought the reMarkable 2, and I absolutely love it.

I know next to nothing about the original reMarkable, but the 2 has cloud support, and it is so nice having all of my notes on my phone and computer, and I am able to adjust notes while on my phone/computer.

That, plus being able to just drag and drop books into the reMarkable app has redefined how much I read

They were built to use in schools and the like years ago, and most of them barely saw any use at all as laptops came out and took over their role. There are a ton of them coming up for sale on eBay that are as close to brand new as they could possibly be. They save files internally, and you can output them to your desktop computer by plugging it in and hitting the send button (it'll emulate a keyboard and type the document straight into something on your computer). There's also a program that can directly import the files, but I'm not sure if that program still works (haven't used it in years - send works). > > You put a pair of regular old batteries in this thing and it'll run -forever-. They last literally months on a single set of batteries. I'm not joking. You can type on this thing for something like 700 -HOURS- on a single set of double a batteries.

As someone who used them in school all the time and got free ones from time to time, alphasmarts if you can stomach the first generation storage spaces. We're talking something like a few gigs if you get a really premium model.

The screen is also something like a typewriter, only having two or three lines visible at a time.

If you do go that far though, there's really no reason to avoid a cheap laptop, which will probably be better in every single way...

I would love an E-ink laptop with a good keyboard to use for writing and Dungeon Master stuff.

It needs to be easy to read from, have a good keyboard and battery life, and play music. It needs an internet connection because all of my tools sync or are web-hosted. Also let it display normal color video out of HDMI or Type-C.

Basically my ZenBook 14 (love this thing) with an E-Ink screen.


AttackingHobo t1_jc7keeo wrote

Do you think there would be a market for a standalone writing device that attached to any keyboard, to emulate the function of those kinda typewriters?


[deleted] t1_jc7pv7g wrote

I definitely think there is a market for these things in general. It's just a matter of price. I would love to own a dedicated typing device with an e-ink screen if it costs $60-$100 and works just like I want it to. I think a lot of people would want that.

Some happy hackers hacked the ROM and replaced the "19" in the year (which was static coded to display 19{yy}) with "20" some time ago.

What about leap years you may ask? The TRS-80 laptop family never actually did leap years, so nothing was lost.

If you can deal with the fact that they only have enough memory to store about 10-pages of text, they are pretty cool machines to write on.

384kB of RAM and a meg of solid state storage and a 96 MHz chip was more in the realm of sci-fi in 1972. Fast forward, and computers like the Mac, Atari ST and Amiga had 512kB, no flash and ran at 7 -8MHz

Not quite. In 1992, 66MHz DX2 processors were available to consumers, and 90MHz Pentium chips were right around the corner. I agree that these speeds were a bit out of reach still in '92, but I think it's a stretch to say it would have been a dream.
