GFS16 - Battery Indicator Tailcap Light & 1mR FET Tailswitch! (Rev B)

If shiczobovineā€™s design uses the same components, I would just order both, 3 of each and wait to see which one works better. Then order more of the design you like. Seems like people are having problems getting the battery installed and your going for the super capacitor. Seems experimental.

Oh now Iā€™ve noticed thereā€™s a place for a linear regulator on the boardā€¦

Silly me thought the cell/supercap was directly connected to the battery supply. Now the wait begins since Iā€™ve placed an ordered for 12x boards.

Iā€™m going to order some of these in a few days. I was hoping the bugs might get worked out before I did.
Which boards did you go with blue?

Iā€™m going to order 12 of Rev B, since I prefer the LFPAK33 footprint.

Still havenā€™t confirmed the payment though.

Do you think I should order 6 of each just to be safe?

Do you think I should go for the 1Oz option, or thicker 2Oz copper option?

Sorry. Itā€™s my 2nd time ordering a PCB.

You can use either one. He describes it back in his first post under the 16mm oshpark link. Itā€™s also in the descripition at oshpark.
If you are using the LFPAK33 that is. :smiley:

Oh no problem then.

Will order the boards right away. Was confused with the Q2 option in the Rev B and the Q1 option in the Rev S, but they are of the same footprint :slight_smile:

Nice, thank you again!

Let us know how it goes Blue. Iā€™m going to wait and see how yourā€™s goes before I order any. I like the super capacitor idea.
Iā€™m pretty sure you already know about Arrowā€™s free shipping. I order everything I can from them. Thought I mention it anyway. :+1:

Yep.

The bigger problem is that only Mouser can distribute the super capā€¦

So Iā€™m going to have to order about a hundred SST-20s to get free shipping.

My GFS16ā€™s PCBs have finally shipped!

They should be coming next week or two weeks after that.

Iā€™ll also be ordering the components soon. Since Iā€™ll be building about 12 of them, there will be 10 remaining.

Iā€™ll be including a dual BeCu springs, a small and a large one.

Who wants in, if I actually manage to build any? :slight_smile:

1. BlueSwordM

2. BlueSwordM

3. Inkidu

4. Shirnask

Iā€™ll take one

Shirnask and Inkidu have been added to the list.

Very interested - I'll take 2, saves me the trouble for sure Thanx!

I donā€™t think many people were reading along in this thread or they would have jumped all over Blueā€™s offer for the loneoceans fet switch with spring.

Iā€™ll take 2 please, and thanks!

Never said free. Will probably sell it at cost, with shipping. It does cost money to actually make it.

It should be fairly easy to build.

Shhhh!

No prob there Blue!

BTW, Iā€™m probably going to include the springs inside of the package if you donā€™t want/need a bypass, although not soldered for shipping not to explode.

A dual spring setup will easily be able to sustain 20A continuously.
Technically, itā€™s 21A for nickel plated, and 24A for silver plated, but itā€™s about the same number for me.

Blue, which super cap did you go with, if you donā€™t mind me asking.
I ordered 6 sets of oshpark boards.

Opps, I fixed it. :person_facepalming:

I havenā€™t ordered the super caps yet, but:

If you want, to lower costs, I can buy in bulk the components with you. Will ship them as quickly as possible.
