Encryption tools:
|

Typical encryption setups for computers include BitLocker for Windows or [LUKS](https://gitlab.com/cryptsetup/cryptsetup/-/blob/main/README.md) for Linux. BitLocker is typically an enterprise encryption tool used for businesses but it can also be enabled on Home computers too if you follow these [instructions](https://www.privacyguides.org/en/encryption/#veracrypt-disk).

Browser Based:
|

Command Line:
|

- [Kryptor](https://www.kryptor.co.uk) - a simple, modern, and secure file encryption and signing tool for Windows, Linux, and macOS. A leaner, user-firendly alternative to GPG.
|
||||
- [Veracrypt](https://veracrypt.fr/en/Home.html) - free open source disk encryption software
|
||||
- Quite popular. VeraCrypt main features:
|
||||
- Creates a **virtual encrypted disk** within a file and mounts it as a real disk.
|
||||
- Encrypts an **entire partition or storage device** such as USB flash drive or hard drive.
|
||||
- Encrypts a **partition or drive where Windows is installed** ([pre-boot authentication](https://veracrypt.fr/en/System%20Encryption.html)).
|
||||
- Encryption is [**automatic**, **real-time**(on-the-fly) and **transparent**](https://veracrypt.fr/en/Documentation.html).
|
||||
- [Parallelization](https://veracrypt.fr/en/Parallelization.html) and [pipelining](https://veracrypt.fr/en/Pipelining.html) allow data to be read and written as fast as if the drive was not encrypted.
|

- Encryption can be [hardware-accelerated](https://veracrypt.fr/en/Hardware%20Acceleration.html) on modern processors.
|

- Provides **[plausible deniability](https://veracrypt.fr/en/Plausible%20Deniability.html)**, in case an adversary forces you to reveal the password: **[Hidden volume](https://veracrypt.fr/en/Hidden%20Volume.html)** (steganography) and **[hidden operating system](https://veracrypt.fr/en/Hidden%20Operating%20System.html)**.

Ideally this would be good to optimize for the typewriter project getting rid of the need to use a pi entirely! Potentially..

### Experiments in PID control with an Arduino UNO R4 Minima-powered robot

In robotics and several other disciplines, PID (proportional-integral-derivative) control is a way for systems with closed-loop feedback to adjust themselves according to sensor data without overshooting the target. Drones, for example, use PID control to remain stable without wild oscillations caused by over-correction. But implementing PID control can feel overwhelming, so Adam Soileau from element14 Presents built a simple robot for some experimentation.
|
||||
|
||||
This robot’s only job is to drive forward until it sees a wall, then stop at a specific distance from that wall. That isn’t hard to achieve when a robot is moving at slow pace, because the code can tell the robot to stop moving the moment it reaches the target distance. But when moving fast, the robot has to take braking acceleration into account and that is much harder to predict. PID control is perfect for this situation, because it adjusts motor output in real-time according to the incoming sensor data.

This is one of the first classes that engineers often had to take (if they were not computer science & didn't get stuck in a functional programming language class like I did) during their freshman year to learn about programming languages. Arduinos are a great introduction into programming because people get to directly see the effects of their program written in MATLAB or something directly onto the Arduino which is a little microcontroller breadboard circuit which connects to code written from your machine to operate.
|
||||
|
||||
I never took that Arduino course though so instead I will have to learn it from scratch from building blocks. Either way there are things I have learned along the way but it's back to basics for me.
