haha well, to be extra careful, I wear gloves during soldering.

Hey @Nca78
Thanks for the suggestion... I just watched this video from sparkfun: https://www.youtube.com/watch?v=f95i88OSWB4
Wow.... I was doing it soooo wrong haha. I'm gonna practice a bit to get my "balls" look more like "volcanos" (yes, still talking about electronics )

Finally!! I got it to work

Using "Continuity mode" on my multimeter, I found out that two connections didn't work. I probably damaged my board during soldering. Using two wires I was able to get it working

One step closer! Thanks again @sundberg84 and @scalz

Again: thanks for the fast replies. Don't guys to work or something?

1. Connecting the GND to the FTDI made my monitor work again
2. Using the multimeter I see the radio gets 3.3 V, so I guess the problem is somewhere in the data pins.
3. @scalz Thanks for the link! I was looking for something like that. I'm gonna read it and I'll return with some questions, or answers

Thanks for the fast reply @sundberg84

I didn't know the capacitor was mandatory, but I've added one.

Before I start measuring using the multimeter, I want to make sure 2) is correct. I removed the VCC/GND connection and only left the RX/TX connected (I don't have reset), but now I don't get any feedback in the monitor at all. I know my PL2303HX isn't the best USB/serial device, but it's the only I have at the moment.

Hi guys,

I'm struggling a bit with building my first battery powered sensor. I have the following setup:

• Rev.8 of the newbie/easy pcb board
• Chinese clone Arduino Pro Mini 3.3v / 8 MHz
• NRF24L01+ radio
• 0.8-3.3 V DC 3.3 V StepUP Boost

I have no sensor attached as of yet, because I get stuck at init. I get a "RADIO:FAIL"

My first thought is: maybe I've done some bad soldering. So my question is: how do I check if all connections are okay, with a multimeter? I have no experience with electronics and soldering, and the multimeter looks like a Star Trek gadget to me

Second question: When I'm using the serial monitor in the Arduino IDE, the Pro Mini gets powered by both my USB connection and the battery (I need it on, because it powers the radio). Is that setup okay? Or is there another way to monitor the debug messages?

Thanks! I'll give it a try

I finally received my EasyPCB boards, and now I want to solder my hardware on to it.

I know how to solder this:

But how do I do this??? Or do I have to cut the pins?

I noticed the build guide says to use data pin 3, however, the sketch from the examples (DhtTemperatureAndHumiditySensor.ino) uses pin 2. So maybe you got a mismatch there as well.

@mfalkvidd you were right!! I used a bit of force to get all pins connected and it worked I'll do some soldering tomorrow! Thanks again!

Hey guys,

I just started on MySensors, and the first thing I did was following the guide. I'm using a Nano V3.0 compatible and I'm sure I got the wiring correct:

But when I upload the SerialGateway sketch, and monitor the COM port, I get this:

0;255;3;0;9;Starting gateway (RNNGA-, 2.0.0)
0;255;3;0;9;TSM:INIT
0;255;3;0;9;!TSM:RADIO:FAIL
0;255;3;0;9;!TSM:FAILURE
0;255;3;0;9;TSM:PDT

Any pointers? I tried different radios from two different sellers.

Thanks for the fast replies! The flappy thing isn't really a flappy thing It's a fixed panel which pushes the mail downwards into the bag and prevents burglars using a wire to open the door. The mailbox itself has brushes, so there actually no moving parts.

Hi all,

I'm using domoticz and 433 hardware for my smart home, and then I stumbled upon MySensors For my first project, I want to monitor my front door mailbox. I have a bag (SecuMax postkeeper) which collects all my mail and packages. What are your suggestions for picking a sensor. It should also be battery powered and must fit somewhere in the bag.
