Nice one! This is a project im working on as well... what kind of IC did you use for the smoke detector? I guess its an optical detector one since you have a smokechamber.
"So as soon as i've checked this is working as before, i release gerbers, and ask for a mini pcba if people interested."
Just in case it was not clear in the other thread, I am
If the quote you get for PCBA is reasonable of course, else I'll shift to the power hungry versions with bigger batteries until I feel confident to solder 0603. Or to re-make the design with sized-up components
The PIR sensor is pretty cheap, but I guess it's already too high for most breakout board sellers on aliexpress who want to keep the price ultra low. I'm just surprised companies like Adafruit or Sparkfun never did anything low power and just resell the 1$ SR501 at 10$
Only DFRobot claims to have a 15µA PIR which is already a great improvement but I can't get it shipped to Vietnam without shelling out 20$ for express mail
Happy new year to you too !
Thanks for the reply. I am not looking to use an LCD, although that may be the best solution. For now, I plan on creating a simple set of LEDs and buttons.
I have looked over the code, and was wondering which part of the code is retrieving the status of a sensor? What if I have multiple motion sensors, how would I retrieve each unique value?

See the first post in this thread for the modifications Konrad did.
@yveaux said in Ikea Molgan Hack:
@magpern the instructions on openhardware.io state that the Molgan must be battery powered while programming:
Well, then I can confirm that you don't have to power the Molgan from batteries just for programming. Burning the bootloader works fine with just power from the ISP port and programming it through FTDI works fine if power comes from the FTDI.
What I found wierd is that the atmega328 had power, the radio had power, it wrote debug messages to the FTDI - when powered through the FTDI, it send radio messages etc, but it just did not receive messages.
Messages where not received until I supplied power to the + / - pads (battery pads).
I did read the instructions on openhardware.io, but I didn't follow then to the t.
