I Don't Want To Set The World On Fire Just Certain Parts Edition

Tech News

  • Xiaomi has another of those little nuclets, like the Chuwi Larkbox.  (Tom's Hardware)

    This one is named the - seriously - the Xioami Ningmei Rubik's Cube Mini.

    It's powered by a quad core Celeron J4125 which delivers acceptable performance for simple tasks, two USB-A ports, one USB-C port, HDMI, headphone jack, and microSD, and measures a tiny 62 x 62 x 42 mm.

    6GB/128GB model is $149, 8GB/256GB model is $186.


  • Social Media Nightmare Misinformation Scenario would be a good name for a rock band.  (Tech Crunch)

    It's Tech Crunch, so...  You know what to expect.


  • Ryzen 5000 goes on sale today and it's already gone.  (WCCFTech)

    If you want a 5900X or 5950X you'll need to be fast and/or lucky.  5600X and 5800X are apparently in better supply.

    Also if you want to watch the first review - it was up on YouTube but now it's disappeared.  Apparently it was set to go public the minute the clocked ticker over to release day when the embargo actually had several hours to run.

    Update: Listed now on my preferred Australian supplier.  The 5900X is A$40 more than the 3900X, which is less than the US price increase.  On the other hand, they don't have any.

    Reviews are back up now.




  • Florida is releasing 750 million mutant mosquitoes.  (BBC)

    They finished counting early so they got to work on their hobby project.


  • An online community for marijuana growers suffered a data breach.  (ZDNet)

    The breach involved Kibana, which is part of the Elasticsearch stack, which long ago adopted the philosophy that information wants to be free, particularly your information.

    The data included hashed passwords, but they were only hashed using MD5, which is pretty easy to crack these days.


  • Massachusetts voters passed a right-to-repair initiative by a 3:1 margin.  (Vice)

    It only applies to vehicles, but it's a start.


  • The New York Times, tired of being merely corrupt, incompetent, divisive, immoral, greedy, and dishonest, has now gone batshit insane.

1 Just to get a feel for the process I "designed" a voltage regulator board.  Nothing special, a USB Micro B input, 2-pin JST connector like used in some rechargeable batteries for output, and a plain old 5 to 3.3V regulator with the normal array of additional components (3 caps and a resistor, all SMD parts.)  Sent it to OSH Park, who built and shipped me 3 boards for $18 ($5 for the boards, double price for rush production because duh, and $8 two-day shipping because it would be dumb not to after ordering rush production.)  Got the boards yesterday and soldered one up today.  Honestly I don't even intend to do the others, although I ordered the parts, and I don't even really intend to use the finished product, as it was just for testing, but it was pretty cool.
Also wired a pushbutton to my ARM board so I could try something--since I used Adafruit's UF2 bootloader designed for CircuitPython, I could double-tap the button to reset the controller and verify that when I do that, the device disconnects from the PC and then reconnects as a tiny flash drive.  You can just drag and drop a new bootloader onto the drive and it will restart itself and flash the new bootloader.
The Adafruit boards that do this make use of a 2MB SPI flash chip.  After updating the bootloader and rebooting, they appear to Windows as a 2MB flash drive.  Save a file named "code.py" onto the drive and the controller will detect that, reboot, and run the program.  So much easier than using the Arduino IDE.

2 I can remember my brother drawing and then etching circuit boards by hand (resist pen and chemical bath) back in the day.  This way is a bit easier!

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
