Gbppr homebrew millitary and espionage electronics

  • 🐕 I am attempting to get the site runnning as fast as possible. If you are experiencing slow page load times, please report it.
At a quick look it’s all a bit “anarchist’s cookbook” -esque. Ie, a lot of it relies on systems and technologies that were already obsolete in the 90s.
There are some interesting looking UHF and microwave radio projects there, but are the applications practical? Doubtful.

And yes the ranting about Obama and corrupt pigs is highly entertaining. Maybe we’ll find the author in the ham radio thread.

Well, I just had a look through his "GBPPR GPS (L1) Jammer", I'm going to say at least this schematic is.. Ok? I mean it'll work, but good luck diagnosing a lot of this if it doesn't work. The 'noise generator' could use a bit of improvement, but will work.

Oxyjen is right here- all this technical stuff is outdated by at least 2 decades, and it doesn't take much to out-do his circuits if you have a bit of know-how and 2024 electronic parts.
 
I love this kind of old schizo site, there used to be a few I'd read occasionally when I was in middle/ high school. Very nostalgic stuff

Edit: Oof. he's in WI, hopefully he isn't making pepperoni.

I've followed GBPPR for a (+/-) decade' and always found the designs useful, wither as food for thought for in an applications sense, or using the functional blocks for other projects. For instance, the 'parallel port bug' using a 50MHz VCO is pretty clever in a simple, non-attributable way that has application in most (any?) low-frequency digital output that one wishes to observe from afar. You can use a different VCO, maybe with a voltage buffer, but the Theory of Operation is sound.

The designs are dated, but can be reproduced with New Old Stock (NOS) components from eBay. Also, a design from NOS looks dated, but still delivers the solution, 'an unconventional use of technology for a *particular* purpose.'

It seems that the Maker/Hacker communities are focused on the latest Small Board Computer (which is cool), but maybe something small and dated is unobtrusive and low-power. Not too mention modern IC's are heavily integrated and maybe that's just too much research on the chip, and the supporting design/hardware for the chip (add an i2c bus and MCU for ADC control), when I just want to ADC as simply as possible.

Also, the programming gap. PIC's and what not.

What's the issue with the white noise generator?
