Project Universal Dimmer???

The dimmer project is slowly progressing with an external push button interface at 240v mains voltage. I try out controlling it via the encoder from a Voltex dimmer. And speculate about using an STM32 and a CANbus network to connect everything together so we can have connected Rotary dimmers up to 6 on 1 wall plate, and more.....

Nice one James, good to see the experimentation continuing across the Tasman. Excellent video again.

Love it, keep it up bro! Good to see you're integrating the momentary Clipsal switch for dimming. Makes it heaps cheaper and neater!

@taddyj6817 3 года назад

Ooo this is pretty much what my boss was talking about the other day. Would be mint when it's done. :)

This project keeps popping up in my youtube feed, we have to make one with a power monitoring chip. Traders powermesh use all TI gear and have that power monitoring built in factory! I imagine a world where every electrical device is serialised with their kwh total output. Diginet make a rotary dimmer that's mean to work with bluetooth also, I believe it's creator/s moved onto Powermesh.

I’ve been distracted by battery build of late, but yes that would be the best thing if all devices measured and shared their power usage maybe even using power line communication. Ever since i’ve had my power use displayed on a real time screen I’ve trying to work out were it’s all going. I’m trying to see if I can power my house entirely off grid, it very challenging I peak out my power use at 43kwhr a day in summer which is too much to generate using solar alone. I have started playing with ACS37800 ic to that end and maybe combining it into a dimmer.

We could use this to replace Clipsal's Cbus. They usually have rubbish dimming for leds anyway. Keep up the good work mate!

@SparkyJames 3 года назад

It did remind me a little of Clipsal Cbus. Instead of letting Cbus die, Clipsal should have made it open source and see if it could have new life with new ideas.

@@SparkyJames They did release the engineering material although I don't feel that's where your project is headed. updates.clipsal.com/ClipsalSoftwareDownload/DL/downloads/OpenCBus/OpenCBusProtocolDownloads.html

nice work mate, I am building a similar circuit for Home Assistant but instead of DAC and level shifter I am testing with the LEDC PWM lib and a second-order low pass filter at 8bit resolution seems to be getting decent control on the dimming. I'll post the circuit once ready, this should reduce the cost further.

@SparkyJames 3 года назад

I’d be interested to see the circuit you use

@jamienewman5419 3 года назад

I'm in NZ and having a hew house built. I'm keen to modify your circuit to allow for say.. a board controlling 8, then another 8 next to it. In a cabinet. Then all lights wires run directly to it. Im going to have cat5 running to switches, then make up some switches with 3.3v logic. Can you think of any thing else I need to consider with running 8 at a time? Oh also running esp32 eth01 ethernet

@Grant-jv6hw 2 года назад

Hi Jimmy any chance or showing / releasing the code use for this project?

@Grant-jv6hw 3 года назад

Hi Jimmy can you share the code used for this dimmer ?

@sonicloud3149 3 года назад

If you were offered a job and paid to play around like this, would you take it? (Presuming it paid well)

@adityakushsolan 3 года назад

Is that a dimmable bulb. Or any non dimmable bulb would work??

@SparkyJames 3 года назад

It it a dimmable light, all dimmers really need dimmable lamps to work properly, most new if not all standards recessed downlights are dimmable now days.
