Introduction: Hacked Dollar Store Junk; Aka: Personalized Colour Shifting Nightlight.
It glows! Yay!
Step 1: Buy Junky Nightlight From Mao's Dollarama or Equivalent.
This is the hardest part. That offgassing plastic is not good for you. Wear a mask. Available in aisle 3.
Step 2: Take Nightlight Apart. and Replace Lame Stuff With Good Stuff
Contained within this incredibly cheap little device is a bunch of doodads. Identify the boring plain white LED and replace with colour (yes, a 'u'. God bless the Queen) shifting LED. I chose a slow blink RGB that I got online, again from our old pal Mao. The LED is the part that glows. It's got two legs that are glued in with metal. Melt metal glue and install LED 2.0 upgrade.
Step 3: Trace a Design on the Lense and Carve It Out.
I used a marker and a Dremel like device. It was red.
Step 4: Behold the Majesty You Have Wrought!
My daughter thinks it's pretty cool. And so do I.
