# N1KDO's Thunderbolt Monitor

## What it is

This is a simple IOT device to monitor the state of a Trimble Thunderbolt

GPS Disciplined Oscillator.

People have made interesting UIs for the Thunderbolt.  This project is not

that.  The goal here is to have a very simple UI using Go/No-Go LED, as

well as a simple Web UI that shows the basic status of the device.

![screen shot showing web UI](screenshot.png)

There is a Green LED that lights up when the 10 MHz oscillator is under 

_discipline_, and a Red LED that lights up when no TSIP traffic has been

received from the Thunderbolt for more than a few seconds.

If the Green "disciplined" LED is lit, the 10 MHz time base is GPS 

disciplined.

## Hardware

This is built on the same hardware as my 

[Rotator-Controller-Controller](https://github.com/n1kdo/rotator-controller-controller),

it has two added LEDs on GP15 (green, 10 MHz disciplined when lit) and 

GP16 (red LED indicates that the Thunderbolt cannot be heard sending data.)

The Trimble Thunderbolt was modified to provide +5 VDC on Pin 1 of its serial

port.  The Rotator-Controller-Controller hardware already has support for 

leeching power from another device on Pin 1.

## How it works

The Thunderbolt emits several TSIP messages every second.  The software 

running on the Pico-W reads and parses those messages.  The most 

important values retrieved are the "minor alarms", "discipline mode",

and various time and date data.  The software enables the green 

"Disciplined" LED when the "Discipline Mode" is "Normal."  The software 

enables the red "comms fail" LED if it has not received any TSIP packets

from the Thunderbolt for a few seconds.
