Someone from a former job emailed me and asked me if I wanted these, I think they're servo drives. diy cnc? if they allow micro stepping you could drive some pretty beefy cnc servos pretty precisely. | 13:44:29 |

 Daniel Peterson | Something really weird just happened | 01:58:43 |
| Daniel Peterson | I was soldering some stuff in my truck and all of a sudden I heard a weird noise | 01:58:59 |
| Daniel Peterson | eventually I realized that every time I touched my solder to the iron I could hear what sounded kind of like mains hum... | 01:59:26 |
| Daniel Peterson | anyone ever notice something like that? lol | 01:59:38 |

eventually I realized that every time I touched my solder to the iron I could hear what sounded kind of like mains hum... Is your soldering iron grounded? | 02:03:37 |
| protocall7 | on a different note, I am working on a project this evening where I need a single NOT gate. I'm using 74LS logic for everything. Designing a PCB with a whole 74LS04 on it for one gate seems really wasteful. Anyone know if there's any downsides to using a BJT inverter with a 2N3904 or 2N2222 instead? | 02:06:00 |
| protocall7 | I need to drive the chip enable pins on 2 74LS241s and a 74LS245 with it, current requirements should be quite low | 02:07:43 |
