Driver giveaway: Constant current 17mm drivers, winners (finally) announced, post #2.

Cool. Nice to see people are still interested, it’s been a while. I did pick you for your dual switch comments so I was hoping you’d want to try it out in dual switch configuration.

I’m not a fan of auto step down, so I’ve only implemented auto step down from boost/turbo mode. All other modes will just warn for low voltage/high temp, or shut off for critical. Voltage and temperature monitoring options can be re-configured.

I do have a battery readout function. You can choose between 1 to 5 blinks, or two digit readout by blinks. So far I have only implemented battery read out from off though, currently no option to check while it’s running. I have a very easy method in my code to add short cuts though, so I can compile your firmware with a short cut for battery check if you want it.

Hmmm. After looking at my list of lights I want to mod in the dual switch category I may have to rethink… Every one of them will require a custom made-specifically-for-that-host-pcb.

One option is to make my own boards for your circuit, strip your driver and build it on my board but I think that kinda makes it so you dont get much actual feedback / data since it’s introducing huge variables (my PCB design) so I’m not sure I really want to do that.

Give me a few days to mull it over. May just go with a standard clicky variant. Do you have any host suggestions for a dual switch light with 17mm driver? On my want to build list I currently have a few sofirns which all take odd-shape drivers with daughter boards and a klarus ST15r which will need the charger integrated into its driver.

Yes please, a spring would be good! Otherwise I may damage it (as I did before with other drivers) :person_facepalming:

Thank you :wink:

Not really. I’ve been using a L4 for dual switch testing with a larger diameter driver med specifically for it. No need to dig up a 17mm compatible dual switch for this driver, go with a single switch host if that’s what you have.

Unless you have a L4 of coarse… I have two Convoy L4s and three driver boards. I could build the third L4 driver and send it your way.

I just have to say, this was one of the best suggestions of them all. I’d never heard of this or thought of it myself but after having implemented this as an on/off setting and have to say I’m hooked myself, I don’t want wrap around anymore either. This is exactly why I made this giveaway thread. You didn’t enter for a driver and haven’t logged in for ages, but if you by chance read this, thanks!

Going on a months vacation this weekend, but pushing to get the drivers in the mail before I leave.

I missed HarleyQuin post, but those are indeed nice suggestions!!!

Wait, if there’s no wrap-around, then what do you have instead? Where does the next click take you when you’ve reached the end?

The next click takes you nowhere. I have both mode up and mode down in my firmware. If you mode change up to the brightest, then there is no more mode to change up to. You use mode down press to go lower. If you are at the lowest mode, mode down want do anything, you can only go up with mode up press.

I made it a setting which can be enabled/disabled. I don’t use many modes myself, normally max 3 including boost, and I really like it. For lights with only two modes in mode cycle I want to be able to wrap around, makes no sense to have it disabled then. Also, the setting has no effect on the UIs that don’t have mode down sequence.

I was trying hard to get everything done before going on vacation but I haven’t done enough testing. I found a few more bugs in the firmware and things I don’t like and have not been able to fix everything in time, and yesterday I found a couple more. I also found that fixing the 1634 version will take as long as fixing the 3217 version so I’ve shifted my attention to them.

So sorry to say I can’t send them until I get back from vacation. Really sorry about the additional delay but I’ve spent so much time with these drivers and firmware already that I really don’t want to send out buggy drivers. Shifting over to the 3217 isn’t what’s caused the delay, the 1634 firmware wasn’t as finished as I thought it was. I haven’t actually been out using lights in the field since my vacation last year.

Anyhow, all of the 3217 drivers for the giveaway are made and tested, they are just waiting for the firmware. I put springs on during reflow, much easier. I can solder on spring bypass and LED wires if wanted. My girlfriend has a lot of studying to do during this trip so I’ll have some evenings to work out the remaining quirks in the firmware. I’ve sent a PM to all giveaway winners.

I might pop in here once or twice during my vacation but possibly not. I might be out of touch until I return in four weeks. Here are giveaway drivers waiting impatiently to be sent off for adventures:

^ Looking gooooood! :+1:

Sorry you’re being forced into a 4-week vacation. Just kidding! :sunglasses:

Have fun. Don’t worry about us. :wink:

Thanks all. I got a little work on the firmware done during the vacation, not much though, but now I’ve been back for a while and have put in a lot of work so it’s getting there. Unfortunately the work trips piled up in my absence from the office. Next I week have to head over to Asia for a few weeks and then on to Mexico. I’ll be bringing my flashlight stuff with me but these work trips are generally not very good for flashlight work… or for my weight… I don’t get any exercise and can’t stop stuffing my face with roti canai.

Anyhow, vacation was nice, the highlight was climbing in the Dolomites. No need for the flashlights though, despite fairly late starts we where never forced to descend in darkness.

Ahah, those “walls” make me dizzy :confounded:
Glad you have a good time and hope you do in the next trips! :wink:
Traveling may be good but it surely is tiring and…having so much great food out there to taste and experiment is a great temptation! :stuck_out_tongue:
I’ve been in Slovakia last week in a Project meeting, and I can tell that sometimes… it is hard to resist!!! :slight_smile:


Thanks. We’ve talked about going to Portugal for climbing with our van, but driving from Sweden it is really hard to ignore the wonderful climbing in Catalonia and continue driving.

It’s not hard… it’s impossible. It’s not doable for me so I don’t even try to resist. Food in Sweden is generally pretty boring. That top right photo of yours… man, that looks really good, exactly my kind of food :stuck_out_tongue:

Ahah! As I’m not into climbing, I’m not sure which are the best places here in Portugal to do that, but in the North and even in some places in the Center of the country you’ll find some places for that! Not like the Alpes or Pyrenees, but we have some places for that, for sure :wink:

Well, that’s a good decision, don’t fight back when the food is irresistable :smiley: I tend to agree that food there is quite good, well cooked, but it doesn’t stand out with strong flavours ! But it is well cooked as far as I can tell!

Those are all things from traditional Slovak food (in Presov, in this case). I cannot remember the names, but it was quite good. But you need to be really hungry to manage to eat all of that :smiley:
My favourite was the top left (dumplings- bryndzove pirohy -, “grilled” onion, bacon cubes, some white sweet sauce) and bottom right (street food with grilled chicken breast, “Placky”, french fries, grilled vegetables with pieces of meat, and some more stuff). Some info here: Eat Local in Slovakia

But…well, if you ever come to Portugal, your drivers will rejoice for what we eat here :wink:

Portugal has plenty of climbing and a good variety of styles. If we go to areas new to us we just get guidebooks, like this one: Portugal Rock Climbing Guidebook

I’m back from Asia, landed this morning. I got a bit of development done while I was away so hopefully I can get these drivers out the door before the next trip. Mexico trip is looming but so far those guys have been silent. I don’t know when I’ll be sent there but I suspect it’ll be short notice as usual.

Thanks for the update. :+1:
