Hi,

Recently I have been more 3D designing and printing, but I like some coöperated practice ;-).

And this point I don't do anything with mysensors, but there are some other longer term projects going on. I'm looking for someone who want's easy housing for there sensors or something.

I prefer it if someone lives nearby and that there will be some coöperation in the designing. I don't intend on making a profit but the material has to be paid for.

At this point I print reliable in PETG (black) and PLA (not in stock)

I am using an adafruit library to communicate with the ic.

I am not cascading them, so I have no idea how to do that part. But controller 1 of them is easy. And when I have my pcb's design finished and ordered and all the parts at home, I will come up with a protocol of how the lights should respond to mysensor messages.

I am building a 4 ch. pwm led dimmer. It's predessor used the PWM outputs from the arduino pro mini, but when ever I am filming or taking a picture I can not dim the light's and when I want to use it as a nightlight I realise there are only 256 steps. Which is not enough.

The PCA9685 is capable of 4096 steps and 1600Hz. Which is not perfect but a huge step forward.

I am not using the arduino pro mini board anymore for the first time. I want to use the bare chip. There is a lot of room on the pcb, but I have yet to do a connector or pads for programming. I ask you to check my scematic and advice one icsp & serial programming connections.

The layout is somewhat similer to the previous version. The tracks that are now under the NRFmodule will be replaced somewhere else. It wil be a double layered board so there a no problems routing. This was sort of my quick and dirty routing.

Nice to see the difference.

How did you produce such a nice result? The text and buttons are very detailed.

Is it SLA printing?

Hi,

Recently I have been more 3D designing and printing, but I like some coöperated practice ;-).

And this point I don't do anything with mysensors, but there are some other longer term projects going on. I'm looking for someone who want's easy housing for there sensors or something.

I have to admit TheoL I've spend some time looking and admiring your work. But I have not found your examples.

I will look into the OTA programming, sounds great. My holiday is over, and the next one starts in july. This topic will probably sink down during this period ;-).

Thank you both for your considerations so far.

I have no need to synchronize multiple lights. At home there are multiple LED Strips used as central lighting. Living room, workspace and almost the bedroom.

In every room I would like a dimmer, but I figured why not always make a 4 channel dimmer and just tell in what mode to behave. (keep the intelligence embedded) This way, It doesn't matter what is controlling it it would do a very predictable set of things.

In the living room only the normal light function would be used. Workroom the same. But I only have to create one type of print and one type of housing.

I asked on Domoticz if they could make an option to start something 30 minutes ( or custom) before a set time. I'm really looking for the simplicity of a normal wakeup light in a digital modes. Not just for the tech savvy ones.

If the wive doesn't like the colour scheme, then it might be better to use only white led.

I have yet to understand OTA, maybe I try it one make make the home functional and then adapt.

I noticed that 'S_Dimmer' has V_STATUS (on/off) and V_DIMMER (dimmer level 0-100) as possible values in table 1, but both are deprecated and replaced with V_STATUS and V_PERCENTAGE according to the next table.

Also a question.

If I want to create a RGBW Wakeup light. I could create a node that does all the thinkering by itself. It will have 3 virtual childs. "Wakeup Light" is a type of S_Dimmer but with a color scene to mimic a full sunset in 30 minutes and the dimmer value is the end value. Normal light (just white) als S_DIMMER. Perhaps a Nightlight, with less blue in it but also an type S_DIMMER.

I could also make an RGBW node and program scenes in my controller (domoticz) although this sounds more flexible it also means more controller programming.

I think it's preferable if the node would do the thinking. If another family member want the same function, I only have to use the same sketch, and the person only has to tell when it wants to wakeup.

The question is: What do you advise me to do?
