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

JS93 · 2020-04-08T17:03:24.000Z

Hi all,

I’m having a bit of trouble ordering the boards from OSH Park. Im using the tailcap switch and LED board in an S2+ Triple but I cant see how I change the board thickness from 0.8mm to 1.6mm?
Is this necesary when using this system in an S2+ host?

During the checkout process you select the “service” you want: 1.6mm standard 1oz, 0.8mm 2oz, after dark, medium run, or rush order. Just pick the standard 1.6mm 1oz service.

Awesome, thanks gchart. Cant wait to make a start on this!

Would anyone be able to suggest an alternative Super Barrier rectifier to the one suggested (SBRT05U20S3)?
I am having trouble tracking on down on digikey.

Thanks

I don’t think the particular diode is critical as long as it’s the SOD-323 footprint. The BAT54 is pretty common and cheap.

Anyway, that reminds me.

I still have a lot of these, and since I’m getting some new soldering equipment pretty soon, I could make some very low resistance switches

I do have the issue of the components being a bit problematic to source however.

BlueSwordM · 2022-03-25T16:39:26.000Z

@gchart, do you know where to get supercaps? I can find all other components still available obviously, but not the supercap.

BlueSwordM · 2022-03-25T16:45:26.000Z

I found it!

Digi-Key Electronics

XH414HG-IV01E | Digi-Key Electronics

Order today, ships today. XH414HG-IV01E – 80 mF (EDLC) Supercapacitor 3.3 V Coin, Wide and Corner Terminals from Seiko Instruments. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

That means I can still build it

It’s also cheaper than when I looked last time, which is surprising.

The super capacitor will provide ~20 uAh to 2 volts so it will likely keep the board functional for a few hours. Then what happens? The light may no longer be operational for a while after that.

BlueSwordM · 2022-03-25T21:35:22.000Z

@hoop, I’m building the GFS16 without the LED board, so once the supercap is fully charged, it’ll stay charged for a long time.

DarkShot · 2022-03-25T22:30:05.000Z

@BlueSwordM color me interested, I’d be down for a couple if you make some, missed out the last time you offered to do some up.

BlueSwordM · 2022-03-25T23:33:39.000Z

@darkshot, no problem.

Now that I have a competent soldering iron again, I’ll finally be able to do some stuff

JS93 · 2022-03-29T04:18:22.000Z

@BlueSwordM, Id also be interested in buying a few if you make them. Is it possible to makethem with the LED board also?

BlueSwordM · 2022-03-29T04:22:10.000Z

@JS93, not with the current boards I have.
I only have the low resistance switches.

I’ll first buy the components for the 10x switches I have, and fulfill the “reserve” list first, and then sell the rest.

If everything goes well, I’ll just order 100x for components and do a small GB for components, and completed switches

BlueSwordM · 2022-03-31T00:00:22.000Z

So, I’ll order the components after my exams.

If I can build one well enough, I’ll start making them myself and then shipping them.

If not, I’ll just sell the components directly to you, my friends

still in

BlueSwordM · 2022-03-31T19:52:38.000Z

Nice, not everybody is dead it seems.

I now have 2 slots left since I don’t really care too much about these switches anymore.

DarkShot · 2022-04-01T00:11:34.000Z

I’ll take ’em.

BlueSwordM · 2022-04-06T16:15:02.000Z

Well, since my XHP50.3 HI GB went to water, I guess I’ll do this first
