chargeitall | Can semiconductors from household appliances such as breast pumps, fridges, and washing machines be used for military purposes? Is this claim far-fetched? | 17:14:29 |
PurpleLady | I don't think most breast pumps would have semiconductors. I don't know too many refrigerators that would need semiconductors either. As for washing machines, maybe. | 17:22:30 |
protocall7 | Guess it would depend on the semiconductor and the military purpose. Something generic like a logic gate could show up in just about anything. A microcontroller could be programmed to do anything as well. As far as whether or not consumer appliances would use "military spec" parts as far as temperature range, shock and vibration, etc... not sure, maybe? | 17:46:12 |
chargeitall | I was referring to removing chips from household devices, reprogramming them with new software, and using them for military purposes such as avionics, GPS, etc. | 20:12:53 |

PurpleLady | Unless the items have like FPGAs in them, the "reprogramming" part doesn't sound likely. | 00:12:21 |

berlinuxer | military specs expexts more robustness, of course. e.g. the temperature-range is wider than for industrial- or consumer-usage. i really doubt, that you will find a IC with mil-spec in household-devices | 13:51:00 |

waitforthe | hi i got a question. here is a picture of my circuit, why is the motor still spining despite not triggered by the pir sensor output (3.3v). transistor is 2n2222. 3v motor 1.5A max draw. 12v power supply. | 20:44:42 |
waitforthe | the pir sensor actually ampliflies the rpms of the motor but the motor still contains a baseline rpm. i thought it should be zero power unless triggered by the transistor | 20:47:01 |
waitforthe | if i remove the motor, it works fine with the led albeit larger resistor | 20:47:42 |

@mriconoclast:matrix.org | you are losing time here | 16:13:28 |
PurpleLady | We are still here. But yeah, there are not mods/admins. | 16:51:23 |
PurpleLady | I might want to start and alternative. | 16:51:36 |
