YouTube has on-video annotations (demo!)

Computers & Mobile Technology

YouTube now has on-video annotations for content creators — so this means if you own the video you can add notes, comments and hot spot areas to click to enhance a video (not URLs, just links to other YouTube videos). This could be very handy for electronic how-tos and “skill building” videos, from identifying parts to sending users to other videos for more information. Here’s a quick example I put together, it’s our Game of Life kit from the Maker Shed Store.

Note: YouTube doesn’t seem to play the annotations all the time via an embedded player, if you don’t see notes on the video visit the page directly here.

In 1970, John Conway came up with a 1-player game called Game of Life. The Game of Life is a mathematical game that simulates ‘colonies’ that grow or die based on how crowded or lonely they are and is known for the way it creates a beautiful organic display out of randomness. Here is a design for a simple electronic project that plays Conway’s Game of Life. Make one kit and keep it on your desk, or attach multiple kit modules together to create a large display.

  • Each kit displays a 4×4 grid (16 LEDs)
  • Connect as many kits as youd like, in any configuration, to create a larger game board
  • Runs off of 2 AA batteries (not included), but can be easily modified to run off of USB or wall-wart power
  • On/Off button to save power, also for resetting the display
  • Automatically resets if the colony has died or stagnated (regeneration)
  • Backwards compatible with older versions
