[jamesone111] bought a Transcend WifiSD card, presumably for photography, but it may just have been because he heard that they’re actually tiny Linux servers. He read a post about these cards…
Those things are ancient, too. It's annoying that there are no tiny cheap Linux SBC's like that, which you can straightforwardly buy.
What I really want is an iPhone charger shaped Linux server that plugs into the wall and has a usb port on it and WiFi. Then I can use it to make any usb device programmable. Printer, webcam, hard drive, monitor, touchscreen, whatever.
Apple's old airport express was kinda that. You plugged it into the wall and it was a wifi repeater, had a USB port to make your wired printer wireless, and a 3.5mm jack for airplay to speakers. It was about the size of a macbook power brick, but for 2004 you can't complain.
Tasmota ones, but the esp32(?) was already mentioned. It's in the greeni wifi plugs, if I recall, and so many others.
Someone posted this further up I remember when they came out but I don't know much about them
True, I remember those, didn't realize they were still around. At that point I'd just as soon use a pi zero though.
That is REALLY cool. I have never seen that! I am going to check that out. It makes a RasperryPi or BananaPi look huge! lol.
Luckfox Pico Mini might be you're looking for. It's a Linux SBC that costs around 10 USD, in a Teensy/Raspberry Pico or even smaller formfactor.
Good to know about, thanks. The wifi version is bigger but the non wifi version is still interesting.
Along the same lines as the Transcend card is Blue SCSI which is a little raspberry pi based SSD for vintage Macs that lets you FTP into the drive from a modern machine for file transfer.
Transcend Wifi SD Card
IsWas A Tiny Linux Server.
8 years ago, this article is from 2016. I wonder what progress was made if any, both security wise and performance wise.
It's come quite a way... O.MG Cable
Just a cable... complete with wifi man-in-the-middle abilities
This is neat. But does it just run a script or can it continuously run software? I’m a little confused by the description.
Follow the videos, the original developer shows what it can do, but it's basically running keylogger software.
I had the FlashAir which is more or less the same thing. Loved it. Used it for quickly retrieving underwater photography without unsealing the camera as well as backing up dashcams, security cameras, and other such quality of life, never have to touch it kind of applications. I would totally buy more if they come back in fashion. Micro SD is probably impossible, but a girl can dream, can't he?
Completely crazy. There are many flash devices with a controller on it, so a small computer, but that this thing has wifi is completely mind boggling.
Don’t forget that every recent Intel CPU contains an extra 486-based system on a chip running a stripped-down version of Minix (a predecessor of Linux), to implement the remote management engine.
May I present the ESP32?

Us hobbyists have been playing with it for years. Dual core too.
Nope, it runs FreeRTOS, but it's still cool that I can build an internet-connected smart device in a package the size of your big toe nail using open software.
Yep, I go for it for almost every project I do, also because of the price. The amount of features you get for like 5 or 6 dollars is crazy.
MCUs can run Linux.
I don't use Espriff products so no idea if it is available for the ESP32.
