Is an electronics craftable (device) but does not craft with:
- biomonitor circuit (78)
- capacitor array (23)
- formatted memory core (8)
- glimmering crystals (1)
- gold processor (28)
- homemade laser (1)
- magnetic coil (17)
- memory stick (32)
- neural bridge (1)
- optical array (1)
- processor chip (19)
- safety loop (19)
- shivering capacitors (1)
- signal analysis circuit (26)
- signal buffer (19)
- targeting circuit (46)
- tear of the earth (2)

EDIT to add a few more, which is all known circuits.
(I had hopes for shivering caps)
