![]() Keyboard forwarding isn't so useful if you can't see what's happening on the screen. I described this behavior in depth in my previous post. This causes the keystrokes to appear on the target computer. As the user types, Key Mime Pi captures the key events and translates them into keystrokes through its fake USB keyboard. It also presents a web page and listens for JavaScript key events. Key Mime Pi connects to another computer via USB and registers as a USB keyboard. Key Mime Pi, my early precursor to TinyPilot that only supported keyboard forwarding. Recent versions of the Pi support USB on-the-go (USB OTG), which allows the Pi to impersonate USB devices such as keyboards, thumb drives, and microphones.Īs a proof of concept of my Pi-as-KVM idea, I created a simple web app called Key Mime Pi. The Raspberry Pi is a fully-functional computer that fits on a single chip and costs only $30-60. The devices are powerful enough to run a full desktop operating system, so their $30-60 price point makes them a popular tool among hobbyists and programmers. The Raspberry Pi is a small, inexpensive single-board computer. So, I did what any appropriately irrational programmer would do: spend several hundred hours building my own KVM over IP. Sadly, they're even more expensive, ranging in price from $500 to $1000 per unit.Īs lazy as I am about dragging servers around, I couldn't justify spending $500 to save myself the trouble of swapping cables around a few times per year. They provide similar functionality to Dell's iDRAC, but they're external devices that connect to a computer's keyboard, video, and mouse ports (hence the name KVM). Next, I looked at commercial KVM over IP solutions. The license alone costs $300, and it requires expensive custom hardware.Ī license for Dell's iDRAC technology costs $300 per machine plus the cost of hardware. I briefly considered an iDRAC for my next home server, but its hefty price tag quickly put an end to that. It's a chip in Dell servers that provides a virtual console from the moment the system powers on. Commercial solutionsįriends have raved to me about their experience with iDRAC. ![]() To get things running again, I have to disconnect everything, drag the server over to my desk, and juggle cables around to connect the server to the keyboard and monitor at my desktop. This is a convenient setup, but it also turns small issues into a colossal pain.Įvery few months, I'll screw something up and prevent the server from booting or joining the network, effectively locking me out of the machine. The server has no keyboard or monitor attached because I access it over ssh or a web interface.

That means you can record from XBOX but probably not from your sattellite or cable box. They can not, however, record HDCP protected streams. ![]() Here are a couple products that can record from HDMI. You're likely going to be paying at least $150 for anything that can record HDMI ![]() You'll need to research that on your own. I'm not sure if PS3 encrypts the HDMI out. If you go with one that only records un-encrypted HDMI you'll be able to record from XBOX but not movies or set-top box content. There are, however a few ultra-expensive devices that do) That adds a significant amount to the price (we're talking $999 and up), and will limit what you can do with the recordings. (actually, upon further investigation, NO devices are supposed to record from encrypted HDMI, it violates the terms of the HDCP liscence. Due to the HDCP (High Definition Content Protection - A form of DRM) in HDMI, only HDMI liscencedrecording devices can record from encrypted HDMI. ![]()
