My initial thought was that you'd need something like I2C between the arrays, and a terminal controller that converted the serial data and pushed it out to the addressable LED arrays - something like www.adafruit.com/product/5409

Are you wanting to pump serial data in one end and get it to transition across each led array one at a time?

You have to wonder what we've done to society that means you'd rather stand there with a phone recording a potential death than get in there and help. Sure, you may not be able to physically assist - but getting in the way of those that can just to get a snippet for your socials? Pathetic.

A couple of passers-by were first on scene and got the occupants of the car out before it burst into flame, and it happens that I know one of those who helped out. Proud to know that while others were videoing the scene, our friend and another tradie pushed them aside to save a life. ...

Also means we don't have to call in a new fire, and go through dispatch to get the crews rolling, we can just roll out and advise ESTA to add it to the current job.

Keeping the job open means we can turn out new crews to flare-ups or reignitions without having to start a new job. Keeps the timeline clearer for a particular fire.

The Responding status should only show once, but it does get updated when new units are turned out, so if that is of interest I can enable that. I figured it would be confusing seeing the same alert with only the number of resources changing.

Safe can also mean it was a false alarm. The feed doesn't distinguish. Generally though you can consider Safe to mean exactly that.

Oh I'm sorry, are you crying? Are you crying because your plagiarism machine that made stuff by copying everybody's stuff was used to train another machine that made stuff by copying stuff? Are you going to cry? Cowards, losers, pathetic

The photo is annotated that it is Victorian firefighters in the Grampians. It is NSW RFS crews and not the Grampians.

Just remembered I have one in my workroom that is primarily there for a USB microscope for working with SMD components.

Having said that, not everyone is up to the task and I don't look down on those who choose not to, or cannot contribute on the fireground. But there are other ways you can help out. Have a fire plan. Enact it on catastrophic days. Don't make the fireys life harder than it already is.

For me it is the quid pro quo of living in the bush. You have to rely on your neighbours in an emergency, so best that you are able to help others as well. It isn't heroism, or looking for gratitude, just an acknowledgement that we are all in this together...

And it isn't just down to those that volunteer. To be a volunteer you need those around you, family, co-workers, bosses, to all be supporting you as you drop everything and run when the pager goes off. It is a difficult ask for many. So why do we do it?...

Keeping a cool head is vital. You can be surrounded by blinding and choking smoke, amid blasting heat and often over difficult terrain. As a driver you need to be aware of the crew on the deck as you pick your way over rocks or chase down a grassfire flank over an unknown paddock...

We all have to make split-second decisions that could mean the difference between a controllable fire and one that could end up taking weeks or months to contain. Those decisions come from experience and training. Is that tussock safe to leave, or will it kick off an outbreak?...

It ended up more than 100Ha (250 acres), but could have been much worse. I was thinking at the time - all these ordinary people coming together and working to a common goal. Then I saw this: youtu.be/g11gy0IjeyQ?... - it reminded me that even though we are all ordinary we are well trained...

Just a DHT22. I had been playing with an ESP32 for another project (an update to our chook mister) and was using the DHT22 to test out the code.

One RPi is used for our media centre, one for monitoring water usage and controlling the pump, one that is used to manage a multi-level chicken brooder. I used to have one for keeping an Ubuntu mirror, and there are a few others floating around.

We do have a Bernoulli thermometer in the room, but it less an accurate meter and more a conversation piece.
Oh, and the RaspberryPi is used to monitor a heater that we sometimes forget to turn off and turns it off when we do. It is one of at least half a dozen around the place.

An Olympic pool is at least 2.5 million litres or 2,500 tonnes of water, or 2,500 cubic metres. Basically a fuck tonne of water. If they had to deal with all of the infrastructure under attack that would be in the millions of cubic metres. A cubic metre is 264 US gallons.

Then add the fire trucks dealing with the fire outside of the buildings - you think they are just waiting for it to hit the urban areas? Keep adding more Olympic pools worth of water.
comment in response to

Add to that the water bombing aircraft in the wooded areas - they vary from 2 to 10 tonnes (or kilolitres) of water each drop. A fire of any significant size will see hundreds of drops, so at least another couple of Olympic pools worth of water.

Lots of reading up on SWD/JTAG debugging, along with ARMv6M - could be a dead end but the investigations have been instructive, so nothing lost either way. Will try and document how I go from here. 4/4

So now I'm thinking, do I use the enclosure with my own electronics or do I see what I can do with the existing hardware? Looks to be quite a capable chip. The existence of the debug header suggests something might be possible, so I've started down that path. 3/4

The timer is a neat unit and I pulled it apart to see if I could use the solenoid valve and enclosure. I was surprised to find a 10 pin connector block - looked like JTAG. Looking further it uses an ABOV A31G112KU chip - ARM Cortex-M0+ based. The header is for SWD debug. 2/4
