Connect an RF 433 MHz Transmitter and Receiver to a Raspberry Pi

I’ve been dabbling with 433 MHz devices over the past few days and tying those devices in with my home automation software named HomeAssistant.  A decent transmitter receiver kit will set you back a whopping $10 or so.  I opted for this one.

It performs extremely well in a home environment and has great specs.

One of the gotchas of this device though is it comes with ABSOLUTELY NO DOCUMENTATION WHATSOEVER.  You’d be hard pressed to find much useful on line as well. So that’s where I come in.

Fortunately the wiring is pretty basic and the pins are clearly marked on the back side of the circuit boards.

RpiTX Replay Attack on GE MySelectSmart Remote Control Outlet

Was walking around Target and saw an inexpensive remote outlet which I was pretty sure I could perform the Replay Attack on.

The Replay Attack  is when you record a signal from something and transmit it back to perform the operation.

These devices typically transmit around 433 MHz and have no encryption of any kind whatsoever.  Just a simple transmit burst for on and off functions.

ProScan on Virtualbox

Proscan  is a wicked cool hunk of software for Scanner Junkies like me.  It lets you take your expensive overpriced Uniden SDS100 (and other) scanners and do cool things with it, like make your scanner accessible to the web, or upload your feeds to scanner apps, etc.  It is worth every penny and then some.

If NOTHING ELSE ProScan allows you to display your LCD screen on a much larger computer screen.

Swiss Army Knives – The Emotional Side

If you were to do an exhaustive search online regarding the subject of Swiss Army Knives (SAK) you would be prone to find lots of historical and technical details and there is a plethora of “What Is The Best Swiss Army Knife?” web lists out there.  If you are a collector, or in my case a new collector, all of that information is GREAT!  But it doesn’t explain  WHY there is a connection between a boy or man and his pocketknife.

First and foremost, it is a tool which grants you independence.  I got my first knife (that I can remember) when I joined the Cub Scouts probably around 8 or 10 years old and in fact it is still in a drawer at my parents house.   Man oh man was I proud of that knife.  I’m sure as a Cub Scout I used it for whittling or to sharpen sticks when playing in the woods or maybe even used the screwdriver on my bicycle to tighten things up.

I truly get the emotional connection when a young boy gets a hardened steel knife. It’s DANGEROUS and by golly you were entrusted to operate it responsibly, and to use it as a TOOL and a LIFE SAVING DEVICE as any good scout is taught.  You are MAN ENOUGH to have something hazardous, maybe for the first time ever.

Swiss Army Knives and Cameras and Tethering and Shit

Hobbies are fun.  Hobbies are hard.  If you have a hobby you somehow or another want to document it for posterity.  If you own widgets such as Swiss Army Knives, Coins, trinkets, whatever then still photography is probably your medium of choice to preserve and document your collection.

But, let’s face it.  Most of us suck at photography.  If only there were a way to use a computer to improve your photography skills…….oh wait, there is.  It is called “Tethering” and tethering is nothing new.  I can’t provide a history lesson but I know I’ve been doing it since the late 90’s or so and it probably came along right with the advent of digital cameras, whenever that was.
