- UI1. It is very good for my use “As Is”. 4 modes with either this “back & forth” style or shot-cycle style is what I like.
UI4: the adjustment goes insanely low BUT the brightness steps go slower at the lowlow end. I have had several adjustable lights back some time ago, where you
had to be really fast to catch the lowest low to stick with you. Not with this.
Not so favorite things to me:
- UI2 & UI3, I´m not a special fan of Boost mode although it might become handy if you use lower mode and just want to take a Quick Peek with higher power mode.
Dual switch light in general, I have owned only a couple of them but again, this is about who prefers and what…
At the moment, I havent programmed parameters. Changed one mode a bit though.
I think as far as I have tested, that this driver works flawlessly! :sunglasses:
The light goes as low as all the way down to 0 in PWM off that single PWM dedicated AMC7135. I slowed it down so once could easily make a moon mode.
I use fast PWM. I tested phase correct PWM, but the moonlight levels where a lot more spaced with phase correct and I couldn’t be bothered to have a routine that switches between fast and phase correct depending on PWM level… So I just kept it on fast PWM through the whole range.
Updated firmware to v1.3, a few changes regarding off time measurements, voltage measurements and timeouts.
Post #3 updated with a video showing dual switch interfaces and mode selections.
Post #4 updated with off time info and a video showing off switch interfaces and mode selections.
Sorry about the quality of the videos, the crappy phone camera kept changing brightness and focusing. And I sound like I’m falling asleep… It was late, I hope what I say makes some kind of sense and it’s not just all mumbo jumbo (a lot of it is). I tried to make the videos short and not just blabber on but I didn’t succeed, they are pretty long. I might have to make better ones later.
Note: The firmware changed slightly since I made those videos but I couldn’t be bothered to make new ones. The difference is with special mode 3 (programming mode brightness for UI 1 & 2 modes). I’ve removed the timeout that exits programming mode. It will now stay in constant programming mode until the light is turned off for about 5 to 6 seconds, so there is no rush to adjust those modes to perfection.
A heads up. A few people have ordered boards through me, I don’t know the progress, but for those that are interested in these boards it might be good to know that I’m taking three months of leave starting 1st of August. My girlfriend and I will be taking our self built camper van on a climbing trip through Europe to be (as Americans would call it) “dirtbag climbers”. so I won’t be spending much time in front of computers. I might pop in once every two weeks or so but I wouldn’t count on it. So if anyone want’s to build one of my drivers (or order a fully built one) within the next three months or so, drop me a PM so we can sort it out before I leave.
We have taken our van through Europe every year the last four years but been limited to four weeks of vacation. Returning from the last was painful, we had the alps in our rear view mirror for hours and hours on our way back. How long do we have to be away to want to go home again? Four weeks is not enough, so now we’re trying three months. Our home away from home:
Thanks. If you want to use some of it for Narsil, feel free. Although a lot of it is specific for my driver design, there might be something of use without much modifications.
Are you sure thats not the Tardis? Looks massive inside. Is the van left or right hand drive? There is no way I could get my head around the steering wheel on the wrong side and driving on the opposite side of the road to what we do here.
It’s not massive inside, I shot that photo with a wide angle lens
Left hand drive. Except for the UK we all drive on the right side of the road here in Europe. I’ve done a fair bit of driving in the UK and Australia and don’t mind right hand drive at all, it just takes a day or two to “convert” each time.
