@waspie The OP said "$1.08 / 10pcs". I presume that means you get 10 for $10.80. i.e. $1.08 each if a quantity 10 purchase.
I haven't gone looking myself. Maybe the OP can comment as to where he found that pricing, but I'd guess he found it on Aliexpress.
@secantscope I understand - It is a few years since I looked into this and then the only conclusion I could make was to take a meter and interface with usb. It would be more work and my needs case didn't warrant that at the time.
I am sorry I could not be of more help in this, but it just seems to be the way things have been for a while. Maybe in the future things will change.
As @nagelc suggested a lesser sensor could be used and you could calibrate it yourself. Seems little other options really. (Now I said that you just wait for a killer posting with just the thing you want linked) !!!
Very nice project you have here! Thank you for taking the time to post/share your work!
At first I thought it might be exactly what I was looking for, but reading through everything now I am not so sure.
I have been studying various ways (Wi-Fi, 433/315 Mhz RF, MySensors) to implement controlling RGB lights and I initially thought Wi-Fi (while readily available, easy, and cheap) might be too "slow" in response time, which got me thinking to use MySensors (with NRF24) instead, which led me to this thread (among others).
Something concerned me though, I see in your GitHub for this project you stated:
Project frozen/final - This project is done from my side. It has been working for years but I switched to another solution so I won't update this anymore.
and on your OpenHardware page:
Update2: They have been running for about 2 years now mostly without problems. The only disadvantage is that my Mysensors network overall is quite "slow" (~1s reaction time). I am currently experimenting with Wifi RGBWW controllers (H801) so there wont be to many more updates to this project
Which made me want to ask you what you are using now?
It seems to me that those MagicHome type Wi-Fi (or RF) RGB controllers would be pretty hard to beat price wise, I don't think I could implement similar functionality (including packaging, etc.) for the same amount of money, and that's before even counting my time.
Also I am still struggling with reliability of my MySensors network in general, but I hope to be able to still solve this as it seems that many others have been able to (but that is a different subject altogether).
@scalz said in Everything nRF52840:
then software support
Is there any particular changes in software that need to be done to migrate from 52832 to 52840? Or do you mean support for additional peripherals?
