This Espressif ESP32-Powered 4G "Smartphone," Programmed in the Arduino IDE, Packs The Essentials

  Nice. The 4g module is $17.90 from digikey, much less than last time I looked. I wonder if there’s a 5g version. I also wonder if there’s any issue using retail sim cards and making LTE voice calls.

      Any particular reason?

  The actual problem isn’t at all making a 4G mini-computer: you can literally buy the necessary parts as modules and wire them together with a a half-way decent microcontroller board and an smallish LED display and then make some code for it in something like Arduino IDE (though I would recommend Platform IO + VS Code instead).

  The problem is making it small (especially thin) and capable of running of batteries for days rather than hours.

  For example, if you’re trying to actually solve the hard part of the problem you would be better of using a micro-controller with an ARM core rather than the ESP32 as those things are designed to use less power. Also you wouldn’t be able to use boards as those things usually waste power versus designing your own.

  Why are people so pissed at this FelixCress guy? He is just wrong, there is no need to debate.

    I’m personally not pissed but I’m not sure if they’re missing something or not. Or just old fashioned ragebaiting. If it’s ragebaiting, they got me.

    Because Felix is wrong and hates technology and the people who make it.

    They probably hate Linux and being a vegan queer furry too.

  I am really interested in where this project goes.

  ESP32 projects are low powered. Not everything needs 5G and the latest Snapdragon.

    Esp32 isnt really known for being low powered when talking about modules like these in general, quite the opposite really.

    Nrf and others are better alternatives

  Is hackster.io any good for tech news? And is it more of a general tech news site or more specialized?
  And if so, any good software/hardware hacking site aside hackaday?

  Are ESP32 secure enough to have them directly on the internets?

  • kn33@lemmy.world ⁨1⁩ ⁨day⁩ ago

    It depends on the code you run on it, really. A lot of the time, too, 4G will be behind CG-NAT which at least means the listening ports aren’t automatically on the internet.

  It is ridiculous. What is needed is a support for advert & bloat & forced updates free smart phone, not reinventing the wheel. Yes, someone must be first - but it is about software, not hardware.

    Hacking isn’t about reinventing the wheel. This isn’t a finished product destined for a market. Even if it was, think about the small business utilities involved in local knowledge (“low-tech”): many small producers (farmers, shops, etc.) still use “obsolete” mechanisms and improvised mechanical technology. If that could reflect personal or community knowledge into real technology, even if “low technology”, that’s already a social gain for those people.

    Besides that, it’s worth it for a personal project where the end goal is obtaining knowledge about how things work in the world. Not everything is about stocks, and stocks doesn’t fill all of the “market” also.

      it can make calls, and send texts," LuckyBor writes of the project, which perhaps stretches the definition of “smartphone”

      … And you need to remove the screen to insert a sim card. Now tell me again this is not ridiculous.

      Take the first one off the shelf smartfone, wipe out the entire software, replace it with bloat free, spyware free, update free equivalent and voila!

      Absolutely no need to reinvent the wheel, this is a road to nowhere.

    but it is about software, not hardware.

    Hey Bestie! Sorry, but you are absolutely wrong here. 😊

    There are several options for free and open source software for mobile applications, and it only works with a teeny tiny sliver of the available hardware because almost none of the hardware is even remotely open. 😭

    At this stage, it is absolutely about hardware that actually supports the OS community, because all the software imaginable is useless if it can’t run on any available hardware! 😁

    Kthx, Lots of Love! 🤩

      They are all shit except jello may be. If it was that good it will be a tsunami into the market. You cannot make a phone with such a poor hardware. 4G said it all

    Aside from the irony, there’s lots to be improved for a Desktop/touch-only computer if you can start fron scratch, vs. the current server hardware and software stack with a desktop HID shoehorned on it.
    Also, can we please get rid of “recalculating a still image 60+ times a second just for the fun of it” and take a “changes-only, the rest buffered” approach? We don’t use CRT displays anymore.
