Projects update

[Recent runs: not much]

Our running and project work has been somewhat disrupted recently.

On the weather station front, I am letting the BeagleBone do its thing at least until the passage of spring daylight-savings-time change.  That will show me if the wview software will handle DST changes.  Next after that is to create a common power supply system that will serve both the weather station and the BeagleBone.  I will probably use a 12 VDC gel cell battery to start with, then look more at solar recharge.

On the GPSDO/Cesium oscillator front, I am still gathering readings  to compare the two.  I have not graphed the total data for about two weeks.  I should do that.  I put the Cesium standard up on ebay and the auction ends on Saturday.  I hope to make oodles of cash but will be happy if I can get enough to pay a couple of recent bills and to maybe buy an Elecraft K2 ham radio.

I received a couple of new projects:

1) A large Pelco flatscreen TV which has a bad power supply.  I think the issue is the electrolytic capacitors, some of them are bulged.  I need to get the PS board out of the TV and take stock of what capacitors I need to order.

2) I bought circuit boards and parts for a KA7EXM PIC Power Meter.  The boards came from the KA7EXM website.  The parts came from DigiKey.  I have the PIC board put together and I have been working on the box and buttons.  Then I will put the RF sensor board together.  I have an issue with interconnects.  That is always a problem for me.   I think I can scrounge enough parts from my junkbox to make it work.
