@megmac you have your reasons but it is really nice to be able to load books from Kindle for the odd title not available on Kobo.

@megmac is there a colour android e-ink tablet at that size?

I love my (ancient) eink android. It has play store so I just use the Kobo app.

@jp ha! Chinstrap beards always throw off the calc!

@jp the inverse ratio would indicate a high Amish or Mennonite load.

@nobodyinperson Honestly, I kind of love this.

I've been pondering a USB cord organizational system and that could be the base of something amazing.

There are a lot of cursed things going on in the world right now.

Let me add my own little cursed tidbit: I've just spent the last 25 minutes pondering implementing CRC32 in #OpenSCAD

You're welcome.

@steven alas, where I thought mine was.

@steven Tera is amazing!

I’ve worked on a decent scale Zola site.

Organic supports in a fleshy colour are kinda creepy.

@sgsax yep. I was looking for shop lights and dismayed they were all integrated now. Give me a cheapo fixture and some standard, replaceable,long, fluorescent like LED array.

@denis my point exactly! Give me bulbs, not an integrated LED array that may or may not work at -45c.

@KaraLG84 I’m generally in awe of pre-2000 software development.

Compute resources and tools were primitive by today’s standards and the market was much smaller.

And learning this stuff was steep! You might get a book, but no tutorials, blog posts or YT how tos.

@Apiary maybe? The least expensive integrated fixtures are the same price as the least expensive bulb fixtures, so it kinda seems the opposite.

I'm building a detached garage and looking at light fixtures now.

It's a sad state: almost all the available (nice) light fixtures have integrated LEDs. I really don't want that: I feel comfortable replacing a bulb but not an hardwired fixture (thus I need to call a sparky to fix).

And when the LED (eventually) dies there is so much less waste with bulbs.

And, where I live, outdoor (LED included) electronics can be hit/miss in the very cold weather.

Am I a weirdo in this preference?

Judging by the Valentine's Day #printables content, I have to wonder if most #3dPrinting enthusiasts are single.

@osb I’ve never been in a data center!

Now in #HomeAssistant, I have a helper that renders as slider and an automation that looks like this:

```
- id: 'xxxx'
alias: White noise vol change
description: ''
trigger:
- platform: state
entity_id:
- input_number.white_noise_volume
condition: []
action:
- service: mqtt.publish
data:
topic: whitenoise/volume
payload: '{{ states(''input_number.white_noise_volume'') | int }}'
mode: single
```

Putting it all together in `/etc/rc.local`:

```
#!/bin/bash

# fix the wifi sleeping issues
/sbin/iwconfig wlan0 power off
# start playing the sound
/usr/bin/play -v 2 -q -n synth brownnoise synth pinknoise mix synth sine amod 0.3 10 gain -20 &
# Read from MQTT
/home/mclinuxface/white_noise.sh &
```

At this point running `mosquitto_pub -h somehost.local -t whitenoise/volume -m '50'` would put the volume at 50%. Yay!

Troubleshooting:

I had more problems with the Pi than anything else. First, I had some boot loop problems, turns out that was due to my particular USB power supply AND my micro USB cable. Then I had intermittent connectivity issues which were caused by the pi going into WiFi power save (why is that the default?).

Here is the slightly redacted script:

```
while read topic
do
if [[ $topic =~ ^[0-9]+$ ]]; then
volume_value=$(($topic))

if (( $volume_value > -1)) && (( $volume_value < 100)); then
amixer -q -M sset PCM $volume_value%
fi
fi
done < <(mosquitto_sub -h somehost.local -t whitenoise/volume)
```

Basically, just ensure that we have a valid volume number then pass that to `amixer` to set the main volume.
