Status 13 Dec

Testing the logic started out OK. Creating a file on Cimbaoth, it was read by the Raspberry Pi, which then signaled the power controller to cycle power which it did.

However, after running a while, it was clear that the power was also being cycled on occasion when it was not commanded.  This caused a need for more complex signaling between the Pi and the controller so it was harder to be misunderstood.

As of this point in time, the logic for recognizing a more complex signal, and for generating that signal, has been developed, but not yet added to the production controller.

ID Estimate Status Description
1044 2016-12-04 Package power control

2016-10-27 09:41:50:  
Develop physical packaging for repeater power control circuit

2016-11-14 08:36:04:  
Holes cut, plugs/jacks mounted, now need to wait for PCB.

2016-11-22 08:12:49:  
Still need outlet

2016-11-26 11:58:05:  
Still need more time, hope to do today

2016-12-02 15:03:29:  
Still having trouble with packaging

2016-12-05 08:11:02:  
Got box to work (sort of), had been connected to a poor choice of
Raspberry Pi pin.  But a new issue emerges.  On boot, the RPi pin
is not an output, must be pulled up because it goes high in spite
of the PIC's weak pull-down. Once getit runs, it gets set low,
and a minute later the plug is pulled.

After about 20 seconds, the cycle starts all over.

985 2016-12-09 Schedule 2030 install

2016-09-12 10:30:56:  
Schedule a time to move the repeater to 2030

2016-11-26 11:58:56:  
Predecessor slipped so slip this one, too.

ID Estimate Status Description
992 2016-12-14 Make backup SD

2016-09-11 09:49:16:  
Need to create a backup SD card immediately before taking
repeater to site

2016-09-12 10:32:15:  
Create a backup of the SD card.  Moved date to the day before
install since this wants to be the LAST thing we do.

2016-11-26 12:01:29:  
Must be 993 - 1 day

ID Estimate Status Description
1042 2016-12-16 Develop short-term firmware

2016-10-27 09:41:49:  
Design and test firmware for the short term repeater power
control, both PIC and Pi

2016-11-14 10:23:54:  
Largely complete
commit 56e57f72d9b15bf1256c4f30ba4dd6a59e5bce3c

Still want to make a new branch with doxygen

2016-12-13 09:22:04:  
Original firmware worked, however, power cycles every 30 minutes
without the Pi software running, so something else was signalling
the controller.

Moving to a more involved signal, where three pulses of specific
length are required to signal the controller to cycle power.

ID Estimate Status Description
993 2016-12-24 Move to 2030

2016-09-12 10:54:35:  
Install the repeater at the permanent site at 2030 building.

2016-11-26 11:59:18:  
Predecessor slipped so slip this one, too.

ID Estimate Status Description
996 2017-01-07 Test 100 watt amp

2016-09-12 10:49:37:  
Repeater will initially be set for 20 watts. It is unknown at
this time whether the addition of an external amplifier will
result in excess desense. After the repeater is at the site, an
amp will be tested for coverage.

2016-11-26 11:59:58:  
Predecessor slipped so slip this one, too.
