This note describes the configuration of an ATtiny85 based microcontroller development board named Digispark and similar to the Arduino line. It is available in many online marketplaces for roughly 1 dollar (e.g., Ebay, Amazon, AliExpress) and is shipped fully assembled, including a V-USB interface (a software-only implementation of a low-speed USB device for Atmel's AVR microcontrollers). Coding is similar to Arduino: it uses the familiar Arduino IDE and is already provided with a ready-to-use bootloader (

Goal: Emulate a Raspberry Pi with QEMU in order to run the Raspbian O/S (based on Debian Linux).
The current setup is not ideal. For one thing, the maximum RAM allowed using the "versatile-pb" firmware is 256 Mb. In addition, only the most basic peripherals, a keyboard and mouse, are supported.
A number of articles have been written on this topic. Most are outdated, and the few recent ones are missing key information.
Task: | |
Access OpenVPN or any Service on Home Network from Public Networks (Hotel) without configuring router and without static IP | |
Step 1: | |
Install OpenVPN on any device connected to Home Network (Raspberry mychoice with pivpn) | |
- Change default OpenVPN protocol from UDP to TCP (Cloudflare doesn't support UDP) | |
- Make a note of TCP port number (default is 443) | |
- Grab the OpenVPN client config file | |
Step 2: | |
Install Cloudflared on Raspberry PI | |
- Create a tunnel |
