wight catchup

Welcome back
Again
:slight_smile:

You did peek inbetween, in all these months, admit it!
But always good to know you around

Oh, a lot happened
More folks here, less DIY and more commercial topics, but we convinced several manufacturers what flashlight enthusiasts really want and that shows on the market. And lots of great firmware development here. Some board design went the proprietary path, boost drivers for 6V/12V emitters made progress, DEL’s findings are the de-facto standard in the FET design.

To some of your notes

1. parasitic drain in (momentary) driver
A great step to lower the current was turning off ADC before going into SLEEP_MODE_PWR_DOWN. That in connection with higher values for R1/R2 had already brought it down to µA values.
About these ~4mA:
@Toykeeper, did you (besides underclocking) re-introduce the watchdog timer (WDT)?
At some point along the way, you had discarded it, presumably to gain space in the 13A. The WDT alone eats ~160 bytes in the firmware, that’s a lot when you want to cram some more stuff in 1k :wink:
LED off with WDT and interrupt lowers the current consumption of the system to way below 1mA, while without WDT my DMM showed ~4mA (again: LED off, just the Attiny who seems to suck this power). So this value sounds quite familiar.

3. voltage measuring without R1/R2
Afaik it’s beyond demo already.
The latest version of Narsil, NarsilM, does not rely on voltage divider any more so should omit the current drain in the divider (and frees Pin7, which of course is awesome).
I’ll see for myself, my latest Oshpark SRK driver should be in the mail any day.

:partying_face:

Hey there wight! Great to see you back here! :beer: :+1: :+1:

Wight, welcome back! We never wrote/read each other on here, but in your absence I joined BLF, ordered and built a wight driver that is still working! Thanks for everything you did back in the day and I am glad you are back!

Welcome back wight. There’s a lot of nice new flashlights and led choices as well since you were gone.
I know not much about electronics but still use your driver designs occasionally.

It's good to have you back, wight!

Good summary Wight.

Now, please start contributing again, openly, and if you can, astonish us with something new, which is sadly needed.

I don’t really think that you have not been following things meanwhile. For 2 1/2 years.

Though this place can get far too intense and burn-out the creatives, which has happened rather a lot. Too much take, very little give. Or understanding. Only the most level-headed have stood the pace.

And don’t get sucked into the dark-side too badly (though the money could be tempting, if you play your cards wight). You might even get to see your name etched on every driver (again).

Condiments?
There is a hotsauce thread

Welcome back!

When you’re interested in drivers:

and
Look in Lexels signature for his drivers

Welcome back wight! I’m glad you’re able to return, and I hope you get to really enjoy BLF once again!

Nice to see you return :+1:

HQ - You caught me, I did peak! :blush: Not much though; I would estimate that I peeked once per 6 months on average. Could you provide relevant links to the boost drivers you are thinking of? I appreciate all the info!

SB - Thanks, it’s great to see so many folks I know still active on the forum.

duramax - I’m glad to be of service!

djozz - So I hear! The Emisar series from Hank seems very good. Someone mentioned the BLF Q8 and BLF GT in a PM; those look interesting and I’ll have to take a closer look at them. Are there any lights from the past couple of years that really stand out to you?

racoon city - Good to see you again!

Tom Tom - I would like to contribute again. We’ll see how it goes. My intention is that if I make any new layouts I would release source materials. I haven’t firmly defined my goals in that respect; I’d have to write everything down and find a license agreement which fits (probably a creative commons one). Making money on flashlights is not a priority for me today, I don’t think I’ll ever break even on my flashlight “investment”. When I do take bribes they’ll be in dark alleys and paid in unmarked flashlights. :wink:

joechina - That definitely looks like good catchup info, I appreciate the links!

DavidEF - Thanks, I’m very happy to be back and I hope to spend some time enjoying myself. :slight_smile:

EDIT:

CRX - :slight_smile: Are you drawing those UI cheatsheet diagrams?

No, just harvesting what’s available and sometimes editing in places.

Here are a couple of loneoceans’ boost drivers that might be of interest:

I joined BLF after you started your break, so I’d like to take this chance to say “thank you” for your previous driver work. I have some of the lights you helped make happen, and they are definitely a step up from the ones I had before that :+1:

Dope, I jumped to a conclusion on that. Thanks for putting it all together in one place.

They definitely sound interesting! I’ve only taken an initial glance, but I see that loneoceans has released the work under the CC BY-NC license which is great as well. I see that loneoceans also has an interesting FET tailswitch project: GFS16 - Battery Indicator Tailcap Light & 1mR FET Tailswitch! (Rev B)

Welcome back amigo!

I’m glad you’re back around CK; you took a long break yourself!

Hello. Who the heck are you? :stuck_out_tongue:

Some interesting Lamps in the making:

IMHO, the Firmware alone is a reason to get it.
