The sensors quest seem imposable to get

[lnee94]

You dont get the quest for the Machine Controller by crafting them and light sensors and node sensors are uncraftable

[TheEt1234]

core.register_craft {
    output = "sbz_power:light_sensor_off",
    recipe = {
        { "sbz_power:sensor_casing_plate", "sbz_resources:shock_crystal",        "sbz_power:sensor_casing_plate", },
        { "sbz_power:sensor_casing_plate", "sbz_resources:simple_logic_circuit", "sbz_power:sensor_casing_plate", },
        { "sbz_power:sensor_casing_plate", "sbz_power:sensor_casing_plate",      "sbz_power:sensor_casing_plate", },
    }
}

is anything off about this

You should be able to craft a couple more sensors now as of #249

Item and node sensors at least. Light sensors seem to be craftable already in the version on ContentDB. I haven't played around with them yet, so let us know if you encounter any more issues.
