Webserver - Gazebo Equipment Box Layout
Webserver - Gazebo Equipment Box Layout
Attached is the first draft of the Gazebo Equipment Box Layout diagram. Only the first sheet is relevant to the March 2018 installation, but Sheets 2 and 3 provide an idea for how to add the Gazebo Pi electronics later.

OK with layout, will drill box and make up base board next week when I'm back.
Can you provide a list of the voltage and current requirements for the various items we may put in the box, please.

Re: Webserver - Gazebo Equipment Box Layout
Penri,
The PSU Brick will be the only device requiring an external PSU I/P and all of the devices will be driven from it. The rated DC I/Ps for the electronics are:
I think that 3.3 A at 12 V should be sufficient, but we will obviously need to test the system in action and if necessary buy a more meaty brick.
The PSU Brick will be the only device requiring an external PSU I/P and all of the devices will be driven from it. The rated DC I/Ps for the electronics are:
- Antenna - 12 V, 1 A.
- Ethernet Switch - 5 V, 0,6 A.
- Raspberry Pi Zero - 5 V 0.7 A (typical, when lightly loaded as we will be).
- Interfaces Board - TBD depending on the design, but should be considerably less than 0.5 A at 5 V.
- Power for Sensors.
- Power for the Gate Valve actuator.
I think that 3.3 A at 12 V should be sufficient, but we will obviously need to test the system in action and if necessary buy a more meaty brick.

Updated Box layout, as agreed this morning.
Any comments; please let me know.

Re: Webserver - Gazebo Equipment Box Layout
This morning I changed the connector on the end of the 12 V PSU Brick (ex Samsung Chromebook; now dead) to suit the TP-Link PoE Injector. Before I started I compared the voltage and noise from this brick and the TP-Link supplied one for the PoE. Result:
I'll bring it along when I come in tomorrow afternoon so that we can fit the system as soon as we have a bit of time.
- Chromebook Brick - Rated 12.0 V @ 3.3 A; actual O/P 12.5 V with approx 30 mV of noise.
- TP-Link Brick - Rated 12.0 V @ 1.0 A; actual O/P 12.07 V with approx 110 mV of noise.
I'll bring it along when I come in tomorrow afternoon so that we can fit the system as soon as we have a bit of time.

Hello Terry
I've found 3 shortish Cat5e patch cables amongst the stuff I've accumulated, they all test out OK. I'll bring them to WMT in the morning.

We'll have a surfeit then. I've ordered three at 99p each.

Re: Webserver - Gazebo Equipment Box Layout
I was about to do the same but decided to root around to see what I had "in-stock" first.
Re: Webserver - Gazebo Equipment Box Layout
It doesn't matter. These are very short - 25 cm. They'll be useful for other things.
