There are GPS antennas that physically can block out signals that are not coming from the sky with a huge amount of decibels. Maybe Aliexpress has some of them in stock? This was heavily ITAR-ed but this ban was lifted recently.

Other option: try to sync against the DCF77 signal from Germany. Not only the beep-beep-beep time signal but also the integrated phase modulation. Jamming VLF is difficult. 77KHz is in the range of ADCs.

Then make a voter: if GPS/GLONASS/Galileo/Beidou is available prefer them, if not fall-back to DCF77. If this fails: free-running.

You can use ESP32 with GPS modules and their PPS signals. The PPS signal from the module often has has a roughly precision around 60ns against the global GPS standard.

With that signal you can PID-control an internal timer of the ESP32 - which then can be used to timestamp audio frames. Send that to a central host over Wifi and you can use your standard localization math.

The trick is to use the internal ESP32 10MHz hardware which automatically kicks timestamps into a register if a GPIO does something. Not using high-level C constructs that must eat their way through x API layers.

This costs like 20€.

With that setup, each pixel on the line sensor would effectively record the full spectral content of the light at that scanned position, all in a single acquisition.

Both are highly renowned security experts.

Even the monthly consumption of toilet paper on a base has this classification.

Learning KiCad took me a few evenings with YT videos (greetings to Phil!).

Soldering needs much more exercise. Soldering QFN with a stencil, paste and oven (or only pre-heater) can only be learned by failing many times.

Having a huge stock of good components (sorted nicely with PartsDB!) lowers the barrier for starting projects dramatically.

But as always: the better your gear gets - the more fun it becomes.

Well until press found out that they had tapped into Obamas encrypted phone calls while flying in the AF1 for a long time.

Have a look at WCH. If you are used to the ST-HAL style you get that stuff running within a hour. They stuff works will fully opensourced compilers.

They basically can shoot (not only throwing!) entire frozen chicken cadavers into engines with zero damage.

The only way they managed break the entire engine was to place little explosives on the turbine wings. Even that didn't cause a fatal disintegration of the jet engine.

Somewhere on YT there's a super entertaining video from a test facility.

It's not factor as long they are not crossing a specific size/weight - jet engines and windows from airplanes are tested to withstand a direct impact.

Directive 2009/24/EC, Article 5 + Article 6

Under special circumstances it's legal within the EU do do this.

And removing a freaking old copy protection dongle to allow emulation of the software you legally are allowed to use falls under this.
