This is a simple one, you take the leads from the transistor and twist them together, then shape to a standard ear loop. The beauty is that the transistors can be unfurled and used at any time.
I came across these transistors at the Dallas Makerspace (join!). The transistors are actually really high end and still work, but we have a BUNCH of them courtesy of an old engineer dying and one of the members going and picking up a large part of this man’s collection of parts (which was immense). These were uber cute and because they are gold plated, totally safe for jewelry use on my sensitive skin.
