RESIST
2k Tempco resistor, scale in mm. I use these tiny resistors to build temperature stable exponential converters for oscillators in modular synthesizers.
Lens: Yashica ML 28/2.8 (reversed) @ f/11 + 12mm extension tube + adapter. I initially went in closer with a full 60mm of extension tubes and a 2x teleconverter but then I was so far in that it was impossible to get anything intelligible.
