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

Final design has not been set at all.

Everybody, it’s only been 2 weeks. You can’t expect a brand new charger to be made that quickly.

BLF projects tend to take a long time. While this one won’t take as long as flashlights projects, things still can be slow, especially with communication.

Depending on the price and how good it is then am in for 1 or 2

rofl… It took years for the LT1 to get to where it is, and we’re still waiting for final options like color and a page to order it from.

I’d go into this with the mindset that it may be ready for Christmas ordering.
Next Christmas.

If BlueSword & Friends can pull it off sooner, we can break out the beer & balloons. If it runs past next Christmas, well, it’s our own fault for not paying him a full time salary to work on this all day, every day even if it triples the price. :face_with_monocle:

Oh, yeah… And I’d like it to have pinstripes and a two tone paintjob. :beer:

I have no complaints, BlueSwordM seems to be staying on top of this project quite well :beer:

Please put me down for one.

Much obliged.

Realistically, you’re probably right on.

I also want two USB outputs for loading i-phone etc.
This reduces further power supply units.

I like the display of the XTAR VC4S. It shows all information for all channels at the same time.

Perhaps every Special Edition thread needs an immovable banner which covers every page, making them impossible to read, and which says:

If you need <group buy product> right this moment, then run away as fast as you can and forget that you ever saw this. These aren't the <group buy products> you're looking for.

If you need <group buy product> within 6 months, please purchase an existing product, post a review on BLF, and come back with feedback on how this project can be slightly better 3 years from now at only 2 times the price.

If you won't need <group buy product> for 2-4 years and don't expect <miracle feature> to be included for <bargain price>, then welcome! Please post to get on our interest list.

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: .
