Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.
@fets So far, I have only built the 5x5 board (but the others should be schematically identical). The only issue I have found so far is that I cannot get the ISP port to work. But I have checked and I have an identical setup on the 1.0 board and that worked, so I suspect the programmer is too weak to drive the net on this one. So it is not a board-issue per se, and might only be an issue on the 5x5 board as routing is the most complex on that one due to the size.
Hello Tilman, this is really a very nice design. I have ordered a pack of PCBs from elecrow, based on your gerber files, and have a few questions:
in your BOM you have listed 5 smd-capacitors and 7 smd resistors, but on the PCB i have solderpads for 6 capacitors and 8 resistors. Can you just explain?
is there a uniflächentaster-model for 2 ways?
i think i have to flash the bootloader first, do you have a tutorial for this, and a sample-sketch for the board?
Thank you very much
@alexsh1 the reason i am using the 18650's is the fact i have a steady stream of them coming in for my large battery packs. I have a couple hundred that aren't dead but just aren't quite up to to the standard i am putting in my big packs.
@yury said in Wall Socket Insertable Node:
Looks cool! Do you have experience with capacities switches? I did not play much with them. afraid to use close to AC interference though...
You need to use a capacitive IC with active shielding, basically you have an extra electrode around your touch electrode and the touch IC will compare capacitive change of the touch electrode with capacitive change from the shield electrode. If the change is due to electrical interference then both electrodes will be changed in a similar way and the IC will not trigger.
