| Jan 9, 2016 at 8:38 | comment | added | RogerParkinson | The 5v version outputs 3.3v, so that would run the ATTiny85 (min 2.7v for 8MHz). But its max input voltage (from the LTC3525 datasheet) is 6v and my battery is delivering 12v, or are you suggesting I discard what I've done and buy a Jeenode instead? Not my preference, or not yet anyway. | |
| Jan 9, 2016 at 6:51 | comment | added | RJR | If voltage is an issue - get a Jeenode and the 5v version of one of these: moderndevice.com/product/jeelabs-aa-power-board | |
| Jan 9, 2016 at 6:06 | comment | added | RogerParkinson | The 12v battery I am using is described here: data.energizer.com/PDFs/a23.pdf it seems to be 55mAh | |
| Jan 9, 2016 at 6:05 | comment | added | RogerParkinson | @RJR good question. 6 months would be great. I looked at the Jeelabs thing ages ago and then forgot about it. So I looked again. I cannot find anything about what range he gets. Mine will work indoors on an AA battery and a coin cell would probably be be fine. But if I use less than 12v on my letter box I get no signal at the receiver. I guess I could try some kind of boost from a lower voltage but I doubt I'd figure that out. | |
| Jan 8, 2016 at 4:26 | comment | added | RJR | Have a look here: jeelabs.org/tag/lowpower - a 24Ah 12V battery seems way overkill. | |
