I bought this "Hakko" smoke absorber on eBay. Is it really Hakko? Or is it some cheap Chinese (or Malaysian, or Indian, or Azerbaijani - I don't mean to be racist. I love the Chinese. They're a fantastic culture) knock-off?

I had to replace an old dimmer switch for one of our lights. The knob just turns and turns, so I though I'd tear it down and see what went wrong with it.

Testing coin cells as a power source for the Micro Pulse Rifle.

The smallest board I have ever produced. A small WS2812B LED strip driver for LIBus which solders directly on to the end of the LED strip.

I thought I'd try out a really really cheap macro lens from eBay with my phone - especially for taking closeup images of circuitry. This is one of the cheapest I could find, and the Chinglish on the box was so fantastic I had to share it with you...

A quick test of using the chipKIT Lenny to drive WS2812B LEDs. This is intended, eventually, to illuminate the warp nacelles of NCC-1701 refit models.

Deflector Dish test using modified nacelle spinner

A quick demo of LIBus controlled sound and lights. One looping sound playing on the right speaker. Press the button, and another sound plays on the left speaker and a signal is sent to the other board to start a blink animation on the LED.
