  • I feel you and as a stepparent to an ADHD/autism kid, it will get extremely frustrating at times. Therapy might be necessary, it will help give you and your kid the skills to build…skills… to deal with things. Professionals are better at it than us. There are a lot of different ways ADHD/autism presents, and they all have different hurdles.

    I highly recommend you start building habits now for the activities they struggle the most with and it is extremely important that you build self-care habits (taking breaks for water, food, shower, etc.), because if it doesn’t become a habit, it will become a struggle, and you will both struggle.

    Its important to keep in mind that your kid will be struggling with happiness neurotransmitters. They’ll be searching for dopamine hits however they can, and it can lead to addictive habits that make things spiral and crash (videogames, foods, anything really)

    The majority of PhDs I work with (we do lab bench-level work) make work suck because they think they know more/better about the work we do and will not listen to anyone. Probably some ego thing or trying to justify their choice. A great litmus test is finding out what they think of grad school, if they say they hated it, they’re usually pretty chill. If they liked it or indifferent then they’ll usually be a pain.





  • Chirp spread spectrum just describes how data is sent, it can’t really be proprietary. It would be like saying waving a flashlight to send morse code was proprietary. The black box part is you say “send this data” then that data comes out of the antenna in the Lora signal. The physical device that connects that data to a signal and visa-versa is what’s proprietary. There could be little tweaks to the transmission that make it work better, like having a slightly non-linear chirp, or some signal processing algorithm that can dig the signal out of some serious noise.

    For the most part, a transmission isn’t proprietary, it’s how that transmission is made and how it’s processed that is. In the case of Lora, the radios are cheap and work incredibly well, so there isn’t much of a reason for someone to homebrew their own.





  • Get on top of a nearby hill and hang out there for an hour or so. The t1000e has a pretty damn impressive antenna for what it is, but it can’t beat height. If you can see it with your eyes, you should be able to hit it with your node. The trouble is if there’s stuff in the way.

    There’s three things that can happen with any radio signal, it goes through something, bounces off something, or is absorbed by something. The more obstructions, the lower your signal. So if you think about a node three blocks away, how many walls does your signal need to go through? In my area that could be 20 houses with 3-4 plaster and cinder block walls it needs to penetrate. If you are on a hill and can see the roof of the house with the other node, that reduces it to maybe 5 walls mine and their signal needs to go through.

    There’s someone on the other side of town that has direct line of sight of the entire city and has a great antenna that can hit my node wherever I am, but I can’t reach there’s from inside anywhere. So I have a node I can stick on my car and another in my roof that can relay my messages to them and hit everyone in town by that route. My roof node in turn acts as a relay for anyone in my surrounding neighborhoods who don’t have that height.


  • Check eBay for used business micro/mini/tiny PCs. They’re pretty cheap, and low power consumption. They’re mostly Intel processors, so that’s what you make of it. If I were you I’d look for i3 processors 9th gen and up, i5 and i7 8th Gen and up for transcoding. They can hardware transcode pretty much anything but AV1, vp9, and hevc 12bit but the processors are powerful enough that they can transcode those to x265/264 to a device or two using the CPU without issues.

    If you don’t plan on transcoding, I’ve had no issues with a 5th Gen i5 NUC doing server things, but I do offload any processor heavy things to my 7060 micro (8th Gen i7) machine if I want it done quickly.
