If you're hammer then all your problems look like nails.

What if things happen just because they're there? The world, as I see it, is exceedingly arbitrary.

I don't remember who said it, maybe nobody, I don't care, today I said it.

Raspberry Pi controlling a cheap digital frequency synthesizer. Some scaling needed for more interesting results.
Life is too short for anything reasonable, but I guess one might still figure out a way to have a little bit of fun by accident.


Never waste your time trying to explain yourself to people who are committed to misunderstanding you.



Anything I can't place a probability on I'm just going to ignore, because that simply means I don't know anything about it.

Relative phase stability of rtl_sdr sticks with common crystal doesn't seem too bad (100 MHz).

Your favourite friend is the one you can watch 9 consecutive episodes of Dexter with, without exchanging a single word. The foundation of your friendship is built on a mutual dislike of other people. Everyone else can only be tolerated on a bi-monthly basis for no longer than two consecutive hours at a time.

This one running now at 2.4 GHz sample clock. Should probably go with 3.2 GHz.
However, I need a nice OCXO for that, and I don't have one at the moment.
Also, I had some trouble with quality of my low voltage (1.8V/3.3V) supply (current demand is pretty high).
You often wonder why people can’t be more like you. You have mastered the art of minimal communication and as far as you’re concerned it’s working. You are awesome, hilarious and delightful, after coffee, over text, to people who actually care about what you have to say. Why can’t everyone else take a leaf?

Children irritate you for no reason what-so-ever. Their energy and spirit drains you. You often wonder if child-free restaurants are actually a thing and keep mentally reminding yourself to Google it.

You are convinced certain people exist for the sole purpose of pissing you off. Everyone has a purpose in life. This must be theirs.

We wouldn’t dislike most people, if people weren’t so ridiculously annoying. We have accepted that our every day life is going to be filled with interactions which we can’t be bothered with.

Sample clock 2.5 GHz now.
Spectrum analysis using rtl_sdr (this one goes up to 2.1 GHz) shows ~1.25 GHz peak on the computer to the left.
There's some crap above the Nyquist limit, nothing to worry about.
