will this driver be available to the community? dont think i have seen a definite answer...
was hoping that the SRK and SRM had the same driver, but no go. so im debating on buying a king, but only if i will be able to get one of these drivers for it
Yes, the plans are to make it available. I’m pretty sure the cost will be $20 or less. I need to find out what an assembly house will charge to build them up. They have a pretty high setup charge for doing a run of boards. I also want to find out what the cost of the circuit board would be with hard gold on the back vs ENIG gold flash.
One thing is it will almost certainly be built as a 2.8A/LED driver. 380 mA regulator chips cost over twice what 350 mA chips cost (and there are 24 of them on the board). It is MUCH more cost effective to stack a single chip onto each section to get 3A if you really want it.
This is great to see that these drivers will be available.There is definite interest here,and I have to say the king's UI from the factory sucks and this would make me like it more.Thanks for the hard work on this Texaspyro and I can't wait till the drivers are available.
that is really cool, good on ya’. If there was a rep system here, that’d = lots of thumbs or green jellies. As it is, you’ll just have to make do with a thank you
Great work pyro! You are a gentleman and a scholar
Looking forward to this one. Will you sell bare boards with programmed MCUs? I’d be fine with building my own up from there.
You’ve built one of the best drivers I haven’t seen yet, but I already want two.
I’ve changed the mode programming up a little. You still enter programming mode by holding the button down while powering up the light. It flashes 3 times. Let go of the button within one second and you are in programming mode like before.
If you keep holding the button it flashes four times… let go of it and it toggles mode memory on/off and resumes normal light operation.
If you keep holding the button and after another second and it flashes five times… let go of it and it toggles PWM slewing between modes on/off and resumes normal light operation.
I am looking into adding a temperature calibration option to the programming options. The temperature sensor on the processor is very precise, but not necessarily absolutely accurate. In fact, they say the readings can be offset +/- 10C between two chips (they are actually quite a bit better than that). The idea is to enter a temperature calibration routine that starts blinking the LEDs. You count the blinks and when the count reaches the actual temperature (1-99C) you press the button to store the real vs measured temperature offset. You could lie about the actual temperature… this would have the effect of shifting the temperature protection control points up or down.
