Sunrise Word Clock – Design

December 9, 2010 Leave a comment


My next project is a word clock inspired by drj113’s instructible on making a word clock.

My design differs from drj113’s original considerably

Design Modifications:

  • Rearranged lettering on the front, giving am and pm yet maintaining a compact design
  • Dimmable LED channels so that i can create smooth time transitions
  • Light sensor so that brightness can be adjusted according to ambient light
  • Superbright power LEDs on the back so that the clock can be used for dawn simulation.

I’ve also decided the frame of the clock will be aluminium, touching this aluminium should toggle the power LEDs on and off (with smooth transition).

LED torch (flashlight) conversion – design

December 1, 2010 Leave a comment


I have this brinkmann 3xLED flashlight. I bought it in a walmart in the USA a few years ago for next to nothing. It isn’t very bright but the body is completely aluminium and the overall build quality is pretty good. I’ve been wanting to supercharge it for a while now so i bought some 3watt star LEDs from bestshop2008hk on ebay. My idea is to use one of these in the flashlight. I’ve put together a simple design to help accomplish this, including a way of heat sinking the LED to the torch case. Read more to see the design.
