An Artsy and Functional LED Filament Lamp

Some projects end up being more objet d’art than objet d’utile. There’s no accounting for taste, of course, but we really like the way commanderkull’s LED filament lamp turned out, and it’s obvious that a fair amount of work went into it. Five COB filament strips were suspended from a lacy frame made of wire, which also supports the custom boost converter needed to raise the 12-volt input to the 60 volts needed by the filaments. The boost converter is based on the venerable 555 timer chip, which sits in the middle of the frame suspended by its splayed-out legs and support components.
