Even when we think we’re communicating in private, whether by email, text messages, private messages on social media etc, the fact is that a bunch of 3rd parties, like tech companies, governments, ISPs and advertisers, all see that data too. And it’s not just that they can see it, they’re actively collecting and analyzing all of it.
One of the downsides of encrypting messages and emails to combat this, is that since so few people are doing that, you will stick out like a sore thumb to anyone who is monitoring the data, and probably will receive closer scrutiny. For example, it’d be pretty easy to filter out all messages that contain PGP headers.
What if we could still encrypt the data, but make it look like ordinary plain text, made up of dictionary words? If it was done in a dynamic way, so it was different for every person, it would be hard to detect using passive data mining techniques. That would allow us to use existing services like gmail, twitter, facebook, reddit etc on the clearnet, while still protecting our message content.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

Great! Preparing the resistance… Did you talk about politics with bunnie? Would love more converage on the ‘right to repair’ and ‘right to tinker’… will it someday be illegal to own an iphone that is NOT reporting our position and discussion? For tax breaks, Apple will do anything. Will it be illegal to broadcast video streams of police abuse at NoDAPL?
Steganography is another method, good for longer messages. After encrypting, each bit of the message is “hidden” in the Least Significant Bit (LSB) of an image.
GIF and PNG work better than JPG.
You get one bit for each color R, G, B so 8 pixels save 3 bytes of data. An 800 x 600 image can conceal 18,000 bytes.
