💬 Touch switch with glass panel (two channels, battery)

I'm sincerely quite interested in where you sourced a battery holder that can hold 3 coincell batteries in series? I had trouble finding one that could even hold two in series, and it was bulkier than the one you've found.

Very nice development.
Do you have any suggestions about a good online shop to get good pcb board double layers for prototyping?

Oh, I understand you. I, too, very need in holders for several battery. I looked everywhere I could. They are only on Alibaba (not Aliexpress), but there they sell 1000 pieces per lot. I found a way out in using a holder for the 2450 under two 2430 batteries and a holder for the 2477 under three 2430 batteries. Here is a link to my favorite store on Ali - https://ru.aliexpress.com/store/1497247

@berkseo I understand. For the Epoxy Fiber Plate to buil any systems where do you buy it? on aliexpress?
I have use this shop but i am not satisfied about quality the double layer epoxy fiber. Do you have any suggestion of online aliexpress shop?

Yes, the quality of Chinese textolite is low. I do not buy it for Aliexpress. I think I will not be able to give you good advice, because I buy a PCB with two-sided lamination in Moscow in the chain of stores for radio fans Chip-Dip - https://www.chipdip.ru/enps// I did not correctly understand your previous question. I apologize for the pun in my previous reply.

@berkseo thanks for your feedback. My english was not clear in my post. No worries. What a pity i know this shop 2 days ago i was in Chelyabinsk i could buy before leaving Russia.

So it was you who put the shrink tubing around the sides of the battery holder to keep the batteries from shorting out?

Yes this is true. By the way, holders that would have been protected for several batteries I never seen on sale

By the way, now I'm testing nrf51 and nrf52. When measuring the power consumption of the nrf51 chip, I have such results: in the sleep mode (mysensor) 1 mA, in the listening mode of the radio 17ma. This is very bad, since the device running on nrf24 and atmega 328 consumes 0.2 mA in sleep mode (approximately) and in 11mA radio listening mode. NRF52, it seems, burnt, the damned Chinese leadership, everything was messed up. If you buy such chips, be careful, the Chinese scheme is incorrect! https://aliexpress.com/item/NRF52832-BLE-5-0-Bluetooth-Bluetooth/32849272443.html

@berkseo Sounds like you need to enable DC-DC mode. Not all modules come with this. The Fanstel ones do though. On some modules you can add it externally after the fact. nrf51 is just a cheap toy to play with and with some limited use cases. I recommend the nrf52 with a good antenna instead. Fanstel has the best PCB antennas in their "F" series. Another good thing about the Fanstel modules is that they are FCC approved, so you won't be blowing harmonics all over the place onto your neighbors.

Can you provide a link to Fanstel?

... It's not entirely clear, is it adding something to the circuit diagram (hardware)? Or is it a software solution, such as writing a value to a register?

Well, it's been a while, so I' going from memory. There's definitely a hardware component for DC-DC that you can see in the datasheet. IIRC, there's also a software enable as well. Really, though, with these chips, the datasheet is your friend for answering most quesitons. There just isn't much other documentation to go by, aside from thread "nrf52 action!",
