Nur mal so als Idee.

Is it too late to get rid of meaningless spinning activity (not "progress"!) indicators?

Just tell me what you're doing! :P

Also, bring back HDD/SSD activity #blinkenlights. They were helpful.

At #38c3, we presented our #BlinkenCity research, which started as a fun art project idea, and ended up as a plausible European #blackout scenario.

TL;DR: Some European countries use unencrypted and unauthenticated #longwave radio to steer parts of their renewable power, enough to potentially cause a Europe-wide blackout.

The control signals can be sent with just a #Flipper Zero over short distance, or via self-built transmitters over a long distance (e.g. using a kite to lift an antenna wire).

The system is also used for street lamp control, allowing for a scaled-up “Project #Blinkenlights” art installation that transforms an entire city into a screen (for astronauts).

The company operating this system has threatened us with lawsuits and (now publicly) denies the risk.

BBSing with some tracker tunes tonight.

OK, now *this* is very much in my #Electronics #MicroPython #LEGO #blinkenlights interest space!!

Adafruit sells ultraviolet Neopixel strips. Has anyone here seen any good projects using them?

How well can you tell which pixels are on when they're not visible light?

Before I forget again, here is the repo for the "supercar" #larsonscanner board.

It's a nice useless #blinkenlights toy, which can also be used to do some #SMD soldering practice.

The #KITT 74' circuit, final (hopefully) revision. If I can't think of anything else to change, I will put it up in a public repo, so you too can waste your time building it and looking at pretty #blinkenlights, animated solely with the power of 74 logic and a 555

The #KITT effect circuit that I designed and simulated in #verilog actually worked at the first try. I'm surprised.
It's done with a 555 and a bunch of 74 ICs. Nothing fancy.

It's also totally useless, unless one needs to drain #cr2032 batteries watching #blinkenlights
