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

Good Luck on your Finals !!!

What is your Major, I think you said EE.

Also interested, put me on the list.

If that doesn’t work out, see if there’s a local hacklab/hackerspace/makerspace near you. Most have 3D printers.

Wow, I don’t know how I missed this, definitely in!

Very cool idea. Interested in one.

I’m interested in two.

Please put me in for one.

BlueSwordM, if you’re doing the design prototyping yourself it would be pretty handy to have a 3D printer available, something like an ender 3 is 150$ and excellent, if you set up a funding thing i’ll happilly pitch in to help get you one, this is quite the work you are putting into this.

I think more than a few people would come up with some money to help you out on this charger.

Thanks JamesB for pointing this out.

Interested, add me for one.

Interested

@JamesB, merci beaucoup.

Thanks a lot.

I’ll have to make a working model though. That includes the body itself, the material type, the display inserted in the model, sample electronics, DC input+USB out, etc.

It’ll be a tough job, but doable.

Also, this may be a bit far fetched, but I could make perhaps make a prototype that can only charge lithium-ion, with all the functions built-in.

That last one would take a LOT of time though, and can’t guarantee it.

I can help with 3d printing, if you’d like.

Below are ONLY NEW additions since last week’s update and the BLF INTEREST LIST file linked to in post #1 have been updated too.
The interest list count now stands at 485 chargers.

POST (S)# NAME

1100 waxing twilight
1101 The_crx
1102 BVH
1103 Ijon
1106 lamper

Please could you (before you post your interest) check the BLF INTEREST LIST file (also linked to in post #1) if you are on the list already? Thank you! :wink:

I passed all entries that are just repeating interest in the charger already expressed in previous posts.
If anyone is not on the list please notify me.

Interested in one. Thanks.

Welp, now I’m forced to include all types of 21700 compatibility, unless I want my charger to be inferior in some ways:

My exams will finish the 17th, so after that date, I’ll go full throttle on this project.

Because, well, what’s the use for comparing to a charger that doesn’t exist?

I have to make this project a reality.

Interested in one

the XTAR makes a Beep once battery charged.
would something like this be on the UC4?
you mention the contacts are better? gold ?

Pro’s Cons Please.
thanks.

Perhaps this reminder should be included in the OP, though it probably wouldn’t help :frowning: . I understand that people simply forget and do not intend to make redundant requests, but this makes extra work for the volunteers who maintain the lists and I really wish we could somehow remind members to check the list before asking to be added. Adding reminders in posts like this doesn’t help because the posts get pushed into the past and because many people don’t have time to read any of the thread and merely want to get on the list.

This issue is common to many BLF projects and we probably need an automated interest/buy list management system, but no one wants to bring it up because then they’ll be asked to write it :smiling_imp: .

Thanks, rost, for keeping this list and sorry for the hassle of checking for names that people should have checked for themselves. Here’s to you :beer: .

Interested in one, please add me to the list.
