Bonus: mom's work room

here it is in motion... this was the smallest nutcracker i could find and he's still a little cramped... but handsome

it has a small fan to blow around bits of styrofoam in imitation of snow while it plays jingle bells. Some sawing and hot glue later...

my mom has a nutcracker collection she adds to each christmas so i decided to swap out the snowman in this musical snowglobe thing...

This paper clip and hot glue patch will have to hold for tonight/until i can get a replacement part

the takeup lever on my singer featherweight sewing machine broke off ... ?

after some wrangling, the raspberry pi composite out feed now displays on the CRT. Here it displays a terminal-based screensaver (cmatrix); it is also monitoring the temperature and humidity in the living room. Next challenge is getting infrared signal working!

This table was a bit taller and more topheavy than I wanted, so I grabbed a squat coffee table from the dumpster and did some Modification. There side compartments for eg the remote, and the inner components are not dangling menacingly.

finally got an rpi running with composite video out.... stay tuned

The neopixel strip has binder clips glued along its length, for easy attatching and removal. There's still a little weirdness in the variable resistors though, may still have some connections to resolder

did some rethinking of the neopixel bike light. Decided that what i really wanted to illuminate was myself, so repackaged the electronics in a small nylon shoulder bag - this bike kit can hold tools, patch kirs, water bottle, etc. Along the way I replaced some components, resoldered some bad connections, and remembered to put the heat shrink tube over the wire before soldering, not after....

some obsolete items from today's Really Really Free Market, just what the tech reliquary needs!

instant rainbow, just add battery.

Hack-a-day has some more information (not by me)

The LED (R) resembled an ordinary monochrome, rather than a typical 3-color(L). A closer look reveals that the driving circuit has actually been built into the LED!

I took this candle decoration apart. It cycles an LED through a series of colors so i expected a driver circuit, but discovered it contained only the LED & coin battery.
the switching mechanism was interesting in that it seemed to mechanically press the battery into the LED leads, rather than carry current itself.
