|
||||
|
||||
## Technical Details
|
||||
My surveillance cameras sit on a separate network without internet access and their RTSP streams are consumed by the Blue Iris NVR software running on a dedicated Windows box. When an object is detected moving through a defined area for certain cameras, Blue Iris is configured to send an MQTT message to the `iot/cameras` topic via the Mosquitto broker running on my media server.
|
||||
|
||||
A Python script kept alive by Supervisor runs on the Raspberry Pi and listens to the topic using the `asyncio-mqtt` module. It receives and tries to decode a JSON message like `{"serial": "SE-N-ZoneB"}`. If the camera's serial is found in a dict at the top of the script, the corresponding audio file is played using Pygame. Controlling which speaker barks is done by muting the left or right channel in the stereo audio file.

||||

||||

## Future Improvements
|
||||
The dog has a lot of false positives from the cameras being triggered by car headlights or small animals<span class="aside"> (like a real dog)</span>. This isn't a big deal since no one is home to hear it bark and it isn't loud enough for my neighbours to hear (I've asked). I would rather have a false positive than a false negative.

The extra peace of mind while I'm away is worth the evening it took to set up. It was very easy to make because I reused the code I wrote for [[Protospace]]'s PA system doorbell that you can find on [GitHub](https://github.com/protospace/doorbell). It operates similarly by playing an audio file based on which 433 MHz doorbell is pressed.

The white flecks turned out to be eggs the aphids were laying. The sticky substance was honeydew, a sugary liquid that aphids secrete.

![[hydro-war1.jpg | underside of a green leaf in a plastic bag. several dozen aphids can be seen on it.]]
|
||||
|
||||
I bought a bottle of Safer's insecticidal soap to use against them. I have a walk-in shower in the downstairs basement bathroom beside the grow room, so I moved all the plants into there. I then sprayed the leaves as much as I could, top and bottom. I let it drain for a while and then rinsed thoroughly with water.

|
||||
|
||||
Three days later I noticed the aphids were still alive. So I bought five more bottles of aphid spray and emptied them into a bucket. I then took each plant out of the system and dunked them in the bucket, covering all leaves and the net cup. I pushed the plants in and out of the bucket forcefully, to make sure all the aphids were flushed off. I then rinsed the plants in the shower thoroughly like before.

|
||||
|
||||
Three days later I did this all over again, just to make sure they were gone. This seemed to work but I noticed the aphids returned a couple months later. It was one of the reasons I decided to end this round of growth experiment.
|
||||
|
||||
## Mould
|
||||
A few weeks after the aphid dunking I noticed some kind of mould or powdery mildew on the strawberry crowns, right in the centre of the plants.

![[hydro-war4.jpg]]
|
||||
![[hydro-war4.jpg | up close view of a strawberry plant crown covered in fuzzy grey mould spores]]
|
||||
|

I assumed this was because I let the plants' leaves get too dense and they were blocking airflow to the crown. The airstone bubbles air into the water reservoir and the only place the humid air can escape is through the net cups and strawberry crown.

The garden uses nutrient film technique (NFT) to continuously deliver a shallow stream of nutrient solution to the plants growing in 2" ABS pipe. A submersible fountain water pump sends nutrients up 1/4" irrigation hose to each of the four pipes. The nutrients flow down the slope passed all the roots and return to the ~25 L reservoir. An air stone oxygenates the water. Two computer case fans ensure adequate [[Airflow|airflow]].

### Aegis Authenticator
|
||||
Aegis is a two-factor authenticator (2fa) app for Android that's free and open source. The killer feature and why I recommend it is that it supports automatic encrypted backups of the database in JSON format. You can unlock the app with a password or optional fingerprint. It supported true OLED dark mode. An alternative app is andOTP but there were [problems](https://news.t0.vc/EQYR/c#williamwchuang1553266688) with the backups' encryption back when I switched to Aegis.

### ThruNite T1 Flashlight
|
||||
This is a tiny rechargeable flashlight that can output 1500 lumens, enough to hurt your eyes if you look directly into it. It has a magnet on the back to stick to things and an optional pocket-hat clip. I liked it so much I've bought three of them and gave one to a friend who then bought himself a couple more.

### Logitech G Pro Wireless Mice
|
||||
I've used a lot of wireless mice, and this one is by far my favourite. It has a USB dongle which I prefer because Bluetooh pairing annoys me. If you disable the LEDs the battery lasts for a few weeks of solid usage.
