Anyone remember how viral "I've fallen and I can't get up" went? This was apparently the main use case and selling point for those devices back then, and it still is now.

  > and it still is now. It's sad to see how all of this tech is just doing one thing: enabling badly run "care homes" to reduce staffing count even further, and generally covering up the fact that we as a society are failing our elders.
  - boffinAudio 5y ago
    On the other hand, as an author of a Fall Detector app I'm pretty proud of the fact that a lot of my users in elderly and care facilities are now able to take a walk around the yard without needing oversight. This has enabled a lot more freedom to some of these people than you seem to be willing to acknowledge ..

      > This has enabled a lot more freedom to some of these people than you seem to be willing to acknowledge .. Ideally, assuming there's no need for qualified special care like with dementia people should be able to live out their old days with their family, in their neighborhood. Not being shunted off to a senior citizen's prison in the outskirts and warded over by technology, because the kids have to move across the world to be exploited by capitalism and quality care with proper staffing is all but unaffordable for the 99%. I agree, apps like yours or the radar piece of tech we're talking about here are a massive gain in quality of life for senior citizens who live on their own or together with their family... but let's be real: that's the utter minority where these devices will be used.
      - boffinAudio 5y ago
        I don't share your cynicism. I think the mmWave thing can and probably will be used to reduce staff in care facilities - but this is why apps that are freely available for use with commodity hardware will always have a market, too. One end of the stick: care facilities optimizing for profit - the other end, families who simply want their loved ones to be taken care of, if they fall while taking a daily walk for health. Having already shipped a fall detector in both hardware and software form into this market (over a decade ago), I can tell you there are far more families taking care of their loved ones with this technology, than there are commercial (capitalist) elderly-exploitation facilities...
GameOfKnowing 5y ago
The breath rate application really got my mind turning here— replacing 2 wearables (breath monitor, fall monitor) with a wireless device, and pulse sensing can already be done by video. Imagine walking into a hospital room or grandma’s home & having full bio monitoring with no tubes or cables…

  In 2014, the ResMed office in Ireland was doing this “off label” with their S+ sleep monitor. They were very close, and the goal/target market was for seniors in long term care facilities.

    Their current website states "S+ is coming to an end. Support from ResMed for the S+ sleep tracking device and app is coming to an end.

Wow. Amazing technology. I would buy the "Human Static Presence Module" in a second if there was a tutorial on how to set it up (code wise). The YT video linked on the page made me way more curious then I thought I'd be.
robocat 5y ago
That board shouldn’t have passed QC? The largest SMD on the first image of the board is severely off-centre.
- GameOfKnowing 5y ago
  Whoa— yeah, that’s hard to un-see. I can’t believe they missed that (and that I did at first glance)
- elcomet 5y ago
  What's the issue with this ?
  - aftbit 5y ago
    It just looks ugly. A slightly larger misalignment could cause shorts on pads above, which would impair the device function, but if it isn't, it isn't.
- crystalmeph 5y ago
  They probably gave the marketing department a QC reject to take pictures with, since marketing can't be bothered to worry about things like proper ESD protection =)
  - jrockway 5y ago
    I would be shocked if they didn't ship that. The capacitor is electrically connected to the pads, and isn't shorting the row of smaller passives above. It's $32.
- jacteh 5y ago
  I think you'd be surprised how lax IPC-A-610 can be. That probably just sneaks in as acceptable for class 1/2 (side overhang <=50%). Even class 3 acceptance criteria allows for 25% overhang.
keville 5y ago
This ought to make for inexpensive home automation sensors that do much better occupancy detection for rooms than pIR sensors, which stall out if you're sitting and don't move enough to trigger "motion" but still want lights on in the room.
- quickthrowman 5y ago
  There are ‘dual-tech’ occ sensors that use IR and ultrasonic sensors to avoid the issue that you mentioned.
  - t0mas88 5y ago
    That would be quite useful for a home office. I now only have hallways / bathrooms set for automatic light because you're always moving there. Do you have a link?
rmason 5y ago
When my late father moved into the nursing home they stuck him in the basement which had long hallways and at the time was mostly vacant. He had a walker and it didn't dawn on us it would ever be a problem. But then he had a fall and couldn't get up. Anywhere else in the facility a staff member would have found him within five minutes. After a half hour and multiple failed attempts to stand he remembered his cell phone and called a Lodge member who took another twenty minutes to get there and help him up. He didn't call me because he didn't want me to know he fell. But his Lodge buddy ratted him out to me and I was able to get him on a list for the first available room upstairs. A device like this could have alerted someone at the facility that he had fallen, this is a very big deal and it's going to save lives.
- bsder 5y ago
  > A device like this could have alerted someone at the facility that he had fallen, this is a very big deal and it's going to save lives. Nope. It will never get deployed. The problem is that when it fails, who is liable? I've said it over and over, but the revolution in biomedical will happen when someone solves the problem of indemnity and not before.
  - aaron695 5y ago
  - gizmo686 5y ago
    You mean devices like https://www.medicalalert.com/fall-detection/ https://www.medicalalert.com/fall-detection/ Or these https://www.consumeraffairs.com/medical-alert-systems/fall-detection.html https://www.consumeraffairs.com/medical-alert-systems/fall-d... Wearable fall detection devices are already a relativly crowded field. The liability doesn't seem to have been a show stopper yet. I don't see why the non-wearable variety should face a substantially higher legal standard (although they do seem more technically challanging).
- throwawayboise 5y ago
  It's sad but most facilities are like this. If you want your elderly parents to have assistance, either move them in with you or hire private help and verify that they are doing what you want. Nursing homes and care facilities mainly exist to drain the assets of the elderly and then get them on medicaid until they die.
amelius 5y ago
Of course, out of stock.

Renaud 5y ago
So I love Seeedstudio and their innovative and affordable hardware. I bought quite a lot over the past years and always been quite happy for the quality. However, they blame the chip shortage for their own inability to manage their inventory. I've had to cancel my last order (all items in stock and paid for at the time). I contacted them after a few weeks seeing the items were not yet shipped. They replied that some items were out of stock. I agreed to remove them. A couple of days later, they reply again that more items (similar sensor as the one featured here) are no longer in stock.... This tells me that that their website isn't showing the actual stock status at the time of order, that their system doesn't reserve quantities for items already purchased, and that they don't really communicate unless you chase them (but they respond quickly). If you purchase anything, have a follow-up ticket within 3 days to make sure they take care of your order and quickly assert whether all parts are available. I like Seedstudio but they need to sort out their logistics and inventory management. My previous order took 4 months to ship and had multiple shortages and delays as well.
