Bistro is not compatible with e-switches. However Tom E has a nice e-switch firmware with all sorts of good features. Have you considered Narsil?
The closest Iāve got is Ferrero_Rocher/Ramping_UI_table.c, which would need some significant changes. Or bistro, which is designed to make e-switch code somewhat easier to write eventuallyā¦ but the code for that doesnāt exist yet. I like the ramping UI basics though:
While off:
Click to turn on at the last-used level.
Hold to turn on at the lowest level.
Double click to turn on at the highest level.
While on:
Click to turn off.
Hold to ramp smoothly (and pretty quickly). Release to set the level. Hold again within a second to ramp the other way.
If the driver used a tiny25/45/85 and had the FET and 7135 on entirely separate channels (not sharing a PWM counter), it would be possible to use both PWM and PFM on a 2-channel driver. What this means is it could ramp much more smoothly at the low end instead of getting stairstep-like jumps at the bottom few levels. Not sure thatās relevant for a light this size, but itās something Iād like to see sometime.
Interested but not committed. Iām already buying pats for a SRK build and my finances will dictate what happens here.
I would like ramping and good threading on the body which would raise my interest. Must have a full shelf like the original, itās a no-go for me without that. Not interested in a ābabyā model.
Something to consider is having the whole group made in one identical batch as another requirement so things donāt go like the A6 did.
Both Roche and Ramping firmwares are good enough, they just lack temp control, if you adjust those for A25 it would be greatā¦ā¦actualy only a few would ever use all fansy firmware features, yet the temp control is a great option
We should also work on the driver cooling, i burried many mosfets trying to cool down the fet especialy while rampingā¦. its strange though, when i use a glued Cu headsink on the mosfet it dies way more rapidly and often than if i just glue the drive with a pure sillicone to the main SRK pcbā¦i am trying to figure that out on a Thorfire XHP70 atm, the mosfet is duying randomly
Mitko, great input on the cooling of those parts.
We donāt want to having dying lights.
Reading your post I remembered those little stick on heatsinks used in PCs. For critical servers I put those on all chips. But then I read that these do not help.
Is the MOSFET the highest part of a driver? Seen from the PCB?
If so, would making the ledshelf (integrated in body) thicker to the point where driver can be attached with screws and the MOSFET pressed against the shelf be done? Nah, wires need to run and future modding would become much harder even if it could.
So hmm what could solve this issue?
If not done reliable Iād say letās go for a not ramping no matter how much I like the idea of ramping
Also besides the technical ideas that are being discussed now I would like to have an addition to the team helping.
Specifically I am looking for a person living in Asia or Australia (the continents)
This means we can have 24/7 coverage of the process.
Idea is to exchange email.
Talk about set details, coming from this thread and discussion.
The party/parties outside BLF doing the actual fabrication/shipping should sent all communication to the whole team.
We should be on the same page about key specs/ideas.
So we could address things fast and be active in this thread when needed.
Current team:
djozz, led connaiseur first class.
Tom E, driver whizz.
The Miller, talkative enthusiast.
If you want to help here, feel free to send a pm to me.
Thanks.
As the biggest problem with srkās is the cooling, how about making the head wall 1mm thicker, cutting the fins 1 mm deeper and having them all the way along the head, even though they are only 1mm deep at the bezel.
This should not add much weight but will improve cooling.
Starting to save up now, trouble is finding a new hiding spot that swmbo wont discover and use to feed the family
In for one, not worried about led or driver those can be changed to suit me later.
Cheers David
ps, This would also make the BLF light different from all the rubbish srk clones :partying_face:
Interesting, just adding a lttle extra cooling.
It does make a difference, I was testing the Darktort and Convoy S2+ te other day. about the same amount of light (Darktort a little brighter), about the same size head. The Darktort has a few very small fins on the head and is stayed cooler then the Convoy. So a little will help.
I think this is something to take along, I mean there must a new head made with integrated shelf, why not tweak the cooling.
Iām in for one, whatever comes out of this effort!
Thanks The Miller for this.
A few thoughts:
Iām split about the direction. On one hand iād just love to find a plain gdāold 3xXML/2000 lm OTF, simple āclick and fireā UI, sub $30 SRK clone to gift around with batteries and charger on top. Everybody loves them. But nowadays i donāt know where to find one.
On the other hand, as a flashlight addict enthusiast, i dream of the ultimate SRKā¦ 10.000 lumens turbo (100W with 3xXHP70?), several well spaced levels, a moon mode and hidden strobe. Fast PWM. What else? Iām not fan of ramping unless there is a physical slider or ring. If the light is designed from scratch i would prefer a more casual body with a good grip and no sharp edges. Neutral whiteā¦
Thanks to DavidEF for his idea of the Light-That-Shall-Not-Be-Named. Canāt wait to see it happenā¦
