This little statuette has been in the works for a while. I guess you could sort of call it an Ikea hack, as the light portion is basically made from Ikea's Jansjö USB lamp.
Since I wanted this thing to be electrically safe, I couldn't just use mains electricity to light up the filament in a normal light bulb and also I didn't want this to be an energy hog, so a low power LED was a good choice. But I still needed a way to simulate a classic light bulb filament, so I bought a piece of side emitting optic fiber and fashioned a coiled filament by wrapping it around a steel bar and heating it with a hot air gun. As it cooled down, the coil stayed in shape even though by default the fiber is very flexible and doesn't really want to hold any shape. Then I made a suitable disc out of phenolic, drilled two holes for the fiber and mounted the whole assembly in a normal E27 light bulb base which I salvaged from a broken light bulb.
I couldn't find a source for reasonably priced and good looking vintage shape light bulbs (I did find a few very expensive ones), I just decided to make one. I took an ordinary small E27 clear globe bulb, broke off the base and emptied the bulb from its contents. I then heated the very top of the glass bulb with a gas torch and pushed it out with a steel pin to form that classic little point on the bulb. Then I just glued the bulb on the base with all the electronics inside.
The steel parts we just pieces of scrap I happened to have and I cleaned them up on the lathe and drilled holes through all of them. As all the pictures of Little Helper I've seen have had a curved "spine" on them, I wanted to have that shape on my statuette as well. I cut a piece of wood to a curve on my bandsaw and pressed the drilled steel tube between them to bend it in a controlled manner.
Finally I had to make a base for the statuette, and I wanted it to have some sort of a function. I immediately thought to make it a stand for Post-It notes which I use a lot of. The stand needed a battery compartment for a single 18650 lithium cell and a charger module, so those parameters gave me the limiting dimensions. I had a few pieces of mahogany board thick enough for the battery so I milled a suitable compartment for the cell and the charger PCB.
