@gohan said in Arduino Pro Mini Shield for RFM69(H)W:
If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it.
thank you just what i thought .
about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol
Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board.
sorry about hijack this topic, i though i was on general discussion
Does this help:

I agree with you that the serial messages are not perfectly documented, but realise that this site has been made (as far as I know) by a bunch of people that share their 'love' for home automation.....
boozz
I hate to disappoint you @micah but @Mike-Musskopf has got a point:
MQ* sensors are power hungry. You may want to connect everything up to 240V via a small PSU. There is a big thread on mysensors about air quality detection.
DHT is not the best sensor for a battery application. Please check BME280 (pressure, temp and hum) or Si7021 (temp and hum) - these would be my favourite sensors for low power consumption.
Small tip - your Arduino Pros must be 3.3V and not 5V for the battery usage.
this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....
Hi @tbowmo, do you mind to explain a bit about the design? I'm interested with your design.
I will use these steps for removing voltage regulator, http://goo.gl/CsZaNg
So the design will be battery > external step up regulator (http://goo.gl/PFt99R - to stabilize 3.3v) > vcc pin ?
with these then I can use my first post design?
Thanks
