Battery button sensor

[Ivan Z]

Yes I have

Great idea for a compact button sensor such as a snailmail notifier or some such.

Any thoughts on hardware debouncing ICs, such as MAX6816, MAX6817, MAX6818? Not to be a backseat driver here :) but something like that would be cool for a dedicated button sensor.

I wanted to make the most cheap device. And not set hardware debouncing.
But set external pull-up resistors to reduce power consumption

Sostware debouncing by delay in interrupt

Cool. Are the 6 buttons onboard, I don't think so??? does it need to wire them external?
Is it a reset button on the pic? Maybe I am too curious lol, I can't read your schem (I don't have diptrace). A schematic img could be useful.
anyway, thx for share :) I have a more complex actuator in design progress, but your can be useful too and is simple :)

oki I see :) so one onboard button, others are external. cool, can be useful. thx

Hi,
I see you use CERN OHL but I do not find the required files in the repo.
Where do you store those?
According to the CERN OHL 1.2 howto, you need to provide the following documentation with your project:
LICENSE.PDF
cern_ohl_v_1_2_howto.pdf
PRODUCT.TXT
CHANGES.TXT

Please check the howto closely for how to use the license, or pick another license.

Append license info

@Ivan-Z , how much do you expect for battery life (assuming a regular 250mA CR2032, in the scenario of a single button, regular daily usage in house lighting.

[Ivan Z]

Update

• Error. Reversed MISO and MOSI
• Append Capacitor C1 on RESET
• Change diode component size to SOD-123
• Append Pad for external LED

Calculate battery life
Capacity rating of battery (mAh) = 250
Current consumption of device during sleep (mA) = 0.02
Current consumption of device during wake (mA) = 18
Number of wakeups per hour = 1
Duration of wake time (ms) = 20
Estimated battery life is: 440.51 days, or 1.21 years.

The device wakes up only when pressed button

This is pretty similar to what I'm currently doing, here. However, mine is just a light switch node, yours is more versatile by the looks of things. Looking pretty nifty though, nice work!

@Ivan-Z Добрый день. Я тут новичек но мне ваше устройство хотелось бы попробовать. Я верно понимаю что тут не хватает документации что бы просто заказать производство плат (или изделий целиком)? Можете ли/хотите ли вы выложить их?

@Samuel235
Sorry. I will write in English.
I want order manufacture this device. But manufacturer said to me that he need gerber and bom files. I want know can I get this files from Ivan? May be I can get this files from design files? What programm need to this?

[Samuel235]

@zeblong, you can generate these from the board files, however i'm leaving this one for @Ivan-Z to discuss with you as this is his device and he knows all details regarding this.
