#123365 - Could work! Responding to: Richard Erlacher's previous message |
Germanium diodes are fast and show low junction capacitance. Some show significant reverse recovery times, though.
Germanium diodes demonstrate fantastic properties. Unfortunately, due to the small band gap the diode quickly mutates to a small resistance at higher ambient temperatures, entirely losing its rectifying properties... Kai |

| great post! | Phillip M Gallo | 08/15/06 15:02 |
| I think the biggest problem is with the AT | Richard Erlacher | 08/13/06 10:22 |
| maybe | Jan Waclawek | 08/13/06 13:28 |
| It's not necessarily the product ... it's the docs | Richard Erlacher | 08/13/06 16:26 |
| OK let them be so | Jan Waclawek | 08/14/06 07:36 |
| It's true, they shouldn't be used by anyone. | Richard Erlacher | 08/14/06 08:27 |
| What would you suggest to use? | Kai Klaas | 08/14/06 10:58 |
| Anything else at all would be fine ... even a PIC | Richard Erlacher | 08/14/06 15:58 |

| Yes, and hundreds of events with Philips, | Kai Klaas | 08/15/06 11:42 |

| Why does this come up so frequently? | Richard Erlacher | 08/19/06 23:19 |
| Because there is so much trash in the www! | Kai Klaas | 08/21/06 10:21 |
| Maybe we can provide a local "fix" for that | Richard Erlacher | 08/21/06 10:38 |

| would be great, but | Erik Malund | 08/23/06 10:36 |
| Kai, I think that would be a WONDERFUL addition! | Richard Erlacher | 08/23/06 12:52 |
| Well, what I am thinking ... | Richard Erlacher | 08/22/06 10:11 |
| Yeah, but what's that to do with ISP? | Jon Ledbetter | 08/22/06 10:20 |
| grits, yes, oatmeal, no | Erik Malund | 08/22/06 10:21 |
| Some of 'em will look, read, and do SOME work | Richard Erlacher | 08/22/06 17:57 |

| The root problem is that the first thing one needs | Richard Erlacher | 08/15/06 17:02 |
| "dedicated programmer" | Jan Waclawek | 08/31/06 02:50 |
| what's difficult to understand ... | Richard Erlacher | 08/31/06 08:03 |

| I would not be quite so sure about that | Jan Waclawek | 08/31/06 08:43 |
| Keep in mind that this is for newbies ... | Richard Erlacher | 08/31/06 12:29 |
| but they still have to build it | Erik Malund | 08/31/06 13:45 |
| Only because it looks simple does not mean... | Kai Klaas | 08/31/06 14:33 |
| he's desperate | Erik Malund | 08/31/06 15:19 |
| there are lots of circuits published like this! | Richard Erlacher | 08/31/06 16:41 |
| I used to have memory mapped I/O in virtual | Erik Malund | 09/01/06 06:23 |

| Once again, you are exaggerating ... | Richard Erlacher | 09/01/06 09:59 |
| the point I\'m trying to make (and believe that I | Erik Malund | 09/01/06 10:46 |

| Its not the cables if you ask me. | Jez Smith | 09/06/06 15:25 |
| an interesting thought | Erik Malund | 09/06/06 15:39 |
| It's probably not JUST this part ... | Richard Erlacher | 09/06/06 16:01 |
| not the cable alone | Jan Waclawek | 09/07/06 01:00 |
