| and use a step down switcher like LM2674 to fabricate the 5V
 use a Power Trends (TI) module. what he need should be about $6 Erik |

| You are righ Kai. I didnt analyse this w | 01/01/70 00:00 | |
| nope, that is why it is called a switche | 01/01/70 00:00 | |

| Thanks.   | 01/01/70 00:00 | |
| Try this simple circuit. It might work | 01/01/70 00:00 | |
