Stand-alone IP KVM device with a web interface with various video capture options and a bunch of features like keyboard/mouse control, ATX control (power/reset/HDD activity), Mass-Storage Device emulation.
- Advanced HID emulator based on one Arduino board. It has mouse support; keyboard works perfectly in a BIOS. The firmware implements a protocol with a check for transmission errors, it will never just hang.
- [Our own MJPG streamer](https://github.com/pikvm/ustreamer) written on C with support for multi-threading and GPU video encoding. It can change the resolution in real time for an HDMI source, report statistics about the video and much more (see [README](https://github.com/pikvm/ustreamer/blob/master/README.md) for detalis).
- Plugin architecture to support a variety of hardware. In the future, we'll be able to support other HID, ATX, and MSD devices. For example, now we are planning to change HID from using the serial port to SPI.
- Backend with clear API that can be used for scripts and alternative UI (for example, you can make a desktop application);
- HDMI to S-Video (not all options work, but these two have been tested) (https://www.amazon.com/dp/B012MDMWLM or https://www.amazon.com/gp/product/B01E56CV42 or https://aliexpress.com/item/32847786071.html)
- NPN transistor for HID reset (almost any NPN transistor: 2n2222 or similar)
- Constant resistors, for transistor/optocoupler(to RaspberryPi) 220Ohm-1kOhm, those from ATX to optocoupler need to be matched for your motherboard (supposedly 330-470 Ohm)
- Capacitors to prevent a power loss caused by the relays and for Arduino stability (rated for 10V or more, 220uF or more)
Pi-KVM OS is based on Arch Linux ARM and contains all required packages and configs to work. To build the OS you will need any Linux machine with a fresh version of Docker (we recommand >= 1:19) with privileged mode (for fdisk and some other commands, check Makefiles if you don't trust us :) )
0. For a clean OS (Like Ubuntu 18) you need to install and configure docker (after adding user in the docker group a relogin is needed), as well as git and make.
2. Determine the target hardware configuration (platform). If you are using an analog VGA video capture device, choose `v0-vga`. If you want to use HDMI with Auvidea B101, choose `v0-hdmi`. Other options are for specialized Pi-KVM boards (WIP).
3. Create config file `config.mk` for the target system. You must specify the path to the SD card on your local computer (this will be used to format and install the system) and the version of your Raspberry Pi and platform. You can change other parameters as you wish:
6. After installation remove the SD card and insert it into your Raspberry Pi. Turn on the power. Raspberry Pi will try to get ad IP address using DHCP on your LAN. Congratulations! Your Pi-KVM will be available via SSH (`ssh root@<addr>`) and HTTPS (try to open it in a browser at `https://<addr>`). For HTTPS a self-signed certificate is used by default.
