The making of the BLF UC4 charger: the start of a new venture, INTEREST LIST, UPDATE 7 (Well, ramping stopped :/ )

Please add me to the list for one. :slight_smile:

PERFECT !!!

I am interested. Thanks!

interested. Thanks!

Throw my name on the list. Seems an interesting project, and I’d like another charger.

While we’re making requests, I’d appreciate if it could send and email/text/notification when finished charging, a camera (what device doesn’t have a camera in 2019?), xray sensor for seeing inside the cells as they charge, and roomba capabilities… oh, and have it ready by Thanksgiving :wink:

Not a bad idea. On a rudimentary level, maybe at least have it emit some loud beeps when charging is done. Of course, it would need to be defeatable so that it doesn’t wake you in the middle of the night, unless you want it to.

Interested in one. Thanks

I’m interest in one!

I was trying to go from moderately reasonable to ridiculous… but I agree at least an audible beep would be cool (provided we can turn it on/off as desired). You can get bluetooth or Wi-Fi radios pretty cheaply, so depending on what they decide to run this thing on (would love a linux based charger, but that is probably too big for this project) it would be trivial to get it sending emails

No, it won’t be trivial. The easiest way would probably be using a third-party relay email service like Mailgun, but even then a frontend should be offered to the user to configure it, and the network connection of course. All this only adds more complexity, unstability and development cost. I think the priority should be just to make a great charger.

Since this would now be a network connected Internet of Things device, you also have to factor in security, security updates, and a whole realm of things that would require perpetual upkeep and maintenance.

MAYBE - bluetooth beaconing technology. Put an app on your phone and get one way notices from the charger. Anything more opens up too many problems.

+1. I’m decidedly against manufacturing more DDoS devices into consumer hands. Every single one of them should be UL-listed (for WiFi/Internet security, a standard which doesn’t exist except in my imagination :wink: ) and then run through a blast furnace, just in case. Charcoal briquettes never get malware.

Because nothing bad ever happens from putting an app on your phone :slight_smile: . I actually agree with you and am just kidding here (it’s late/early), but perhaps you’re not Amish enough :smiley: .

Perhaps I should clarify, depending on what it runs (software and hardware) it would be trivial for me to add this to my own unit AFTER production. I have a raspberry pi zero (runs about $5) that I set up as a drop camera. It powers up on a schedule, takes a picture, emails the picture, and shuts off to preserve battery. This project was something I did for fun, and it took longer to source the parts/accessories than it did to write the scripts to make this happen. I didn’t have to set up a mail relay, I just send the emails directly from the pi. There are plenty of safe ways to make this work.

Agreed. Most of my suggestions were facetious in the first post on addition features. I think a charger that just works is a wonderful project. The idea of having a notification (audible, visible, or otherwise) seems to resonate with at least a few of us… but it doesn’t need a complicated implementation. A beep would suffice for most.

EDIT (to add)

I don’t think we need an IOT type of device here, and I agree with much of what you two said. It would be great if the device had some sort of output like a serial (or USB) port that would give live data. This could be hooked up to a computer running something a bit more trustworthy/verifiable like an SBC with Linux.

If it has an LED indicator that lights up when the cells are charged, this could be wired as a signal to another device to do the notifications.

Please add me to the list as well BlueSwordM for 1 unit

Up to date interest list

Total quantity (at the moment): 297

Put me down for one. Thanks

For what it’s worth, I suspect that many readers understood that you had tongue firmly in cheek, but it’s always difficult to convey undertones to everyone, especially those who may not use English as their primary language. Emoticons help, but there are still tons of things lost in translation, even if no translation occurs.

I’m being facetious about half the time and thus am misunderstood nearly half the time :wink: .

At least I’m in good company :smiley:

I had a college chemistry professor that encouraged us to use a :slight_smile: when emailing him so he knew we were not upset (even if we were) so he could sleep better.

I try to keep it light as this is my hobby and I do it for fun. I’ve “met” lots of great people here, and am frequently impressed by the helpful and friendly responses I see.

I have heard people say that sarcasm is not really a “thing” in many Asian cultures.

I am interested!
