The ybox2 is the second-generation networked set-top box in an Altoids tin. Inspired by the original ybox, created by Uncommon Projects. Total cost to build one is around $50, much cheaper than the original.

Kits are now available! See below for details.

Hardware features include:

• Composite video output for TV display (NTSC/PAL)
• 10BaseT Full-Duplex ethernet interface
• Infrared sensor for remote control
• RGB LED for status at-a-glance
• Integrated piezo-electric speaker
• Easy access to most of the I/O pins and power rails, for tinkering
• New in v1.1! Easy access to all I/O pins and power rails via 0.1" grid alligned headers, which allows for the creation of snap-on extension boards!

Ratings:

• Input voltage: v1.1: 6-9 volts DC (Higher voltages will cause excessive heat)
• Input current: 250mA average, 300mA max

Software Features:

• Bootloader which allows upgrades over the network (Requires 64KB EEPROM)
• Integrated web server
• DHCP

Kits

You can buy the ybox2 kit from Adafruit Industries for $75, which will save you from having to try and find all of the parts yourself. You can also buy just the ybox2 board for $15.
