[Hackrf-dev] Current, reasonably priced external clock?

[Mark Lachniet]

Who knew it would be so obscure.  I guess everyone is using nice desktop 
sized clock signal generators?

I really want one that will run on 12v DC current if possible. 
Potentially to make a HackRF/Pineapple/TXCO clock combo that could run 
on the 12v of a car after I stuff it in the dashboard out of sight.  
Maybe even with a cell phone/CAM+OBDii add-on for remotely fiddling with 
car telemetry.  It would be hilarious to prank someone so their car 
shuts down whenever they get near the local police department and then 
have their in-car GPS tell them they were at Starbucks or something.  
(white hat PoC of course, no I would never actually do this to anyone  
in production except maybe myself in an empty parking lot for yucks)
