 **BitDefender Box**<br>[![__](https://i.ibb.co/YjtJLH6/25.jpg)](https://amzn.to/31XwpNg) | An easy-to-use home firewall to block malware, and other attacks for all internet-connected devices. Has other additional features such as parental controls, and requires no technical knowledge to set-up
 **Solo Key**<br>[![__](https://i.ibb.co/8PFQRDy/26.jpg)](https://amzn.to/37CsOpj) | Another FIDO2 physical security key for 2-facto authentication and storing encryption keys. SoloKeys have both open source hardware and software, they are easy to use out of the box, but can also be used for developers and makers, since there is a well documented CLI

+## DIY Security Products
+
+Don't want to spend money? Most of the products above, plus some that wearn't included can be built at home with some pretty simple hardware and open source software. The following list will point you in the right direction to start making!
+
+- **Network-wide add-block** - [Pi Hole](https://pi-hole.net) is a simple yet powerful app, that can be installed on a [Raspberry Pi](https://amzn.to/36GNpsm), and once you've updated your routers DNS servers to point to it, all resources on the blacklist will be blocked, at the point of origin. This makes it much more powerful than a browser add-on, and will also speed your internet up
+- **Encrypted USB** - You can use [VeraCrypt](https://www.veracrypt.fr/en/Home.html) to create an encrypted USB drive, using any off-the shelf [USB drive](https://amzn.to/2RykcLD) 
+- **Home VPN** - [Pi_VPN](https://www.pivpn.io) lets you use [OpenVPN](https://openvpn.net) to connect to your home network from anywhere, through your [Pi](https://amzn.to/2uniPqa). See [this guide](https://pimylifeup.com/raspberry-pi-vpn-server) for set-up instructions. This will work particularly well in combination with Pi Hole.
+- **USB Password Manager** - Storing your passwords in the cloud may be convinient, but you cannot ever be certain they won't be breached. [KeePass](https://keepass.info/help/v2/setup.html) is an offline password manager, with a portable ddition that can run of a USB. There's also an [app](https://play.google.com/store/apps/details?id=com.korovan.kpass). See also [KeePassX](https://www.keepassx.org) and [KeePassXC](https://keepassxc.org) which are popular communnity forks with additional functionality
+- **Automated Backups** - [Syncthing](https://syncthing.net) is a privacy-focused continuous file synchronization program. You can use it to make on-site backups as well as encrypted and sync your data with your chosen cloud storage provider
+- **Bootable Drive Eraser** - You can flash the [DBAN](https://dban.org) or [KillDisk](https://www.killdisk.com/bootablecd.htm) ISO file onto a USB, boot from it and securly, fully wipe your hard drives. This is useful to do before selling or disposing of a PC.
+- **Deauth Detector** - Since most wireless attacked begin by sending out deauthentication packets, you can flash SpaceHuhns [DeatuhDetector](https://github.com/spacehuhn/DeauthDetector), onto a standard [ESP8266 NodeMCU](https://amzn.to/2v5grV0), plug it in, and wait to be notified of wireless deauth attacks
+- **Tor WiFi Network** - Using [OnionPi](https://github.com/breadtk/onion_pi), you can create a second wireless network, that routed traffic through Tor. This is very light-weight so can be done with just a  [Pi Zero W](https://amzn.to/2Urc0hM). Here is a configuration [guide](https://www.sbprojects.net/projects/raspberrypi/tor.php)
+- **Faraday Case** - If you want to block signals for devices such as car keys, smart phone, laptop or even just RFID-enabled cards and passports, you can line a box or pouch with [Faraday Fabric](https://amzn.to/2ORKtTr)
+
+If you are confident with electronics, then you could also make:
+- **USB Data Blocker** - By simple removing the data wires from a USB adapter, you can create a protector to keep you safe while charing your device in public spaces. See [this guide](https://www.instructables.com/id/Making-a-USB-Condom) for more info (note: fast charge will not work)
+- **Hardware Encrypted Password Manager** - Even better than a software-encrypted password manager, is the [hardpass0.2](https://bit.ly/3bg4Xi4) which is a very simple hardware-encrypted USB store, using [GnuPG Smart card](https://www.g10code.com/p-card.html), [GNU Password Standard](https://www.passwordstore.org/) and this [source code](https://github.com/girst/hardpass-passwordmanager) all running on a [Pi Zero](https://amzn.to/2Sz0vU4). See also the [Zamek Project](https://bit.ly/36ZJrec), using this [source code](https://github.com/jareklupinski/zamek) to achive a similar functioning hardware-password manager
+- **U2F USB Token** - Similar to the FIDO2 2-factor authentication USB keys, [U2f-Zero](https://github.com/conorpp/u2f-zero) by Conor Patrick, lets you turn a Pi Zero into a second-factor auth method. Note: project no longer activley maintained, see [NitroKey](https://github.com/nitrokey) instead
+- **PC auto-lock Flash Drive** - Turn a flash drive into a lock/ unlock key for your PC, allowing you to quickly lock your device when needed [deprecated]
+- **Headless Pi Zero SSH server** - Create an small test server, that you can SSH into for development, in order to not have to run risky or potentially dangerous code or software directly on your PC, see [this artticle](https://openpunk.com/post/5) for getting started
