Hi Phil.

I checked and there's no problem with your code. It looks like it's a hardware issue. I'll be sending out a replacement board to you. Can you confirm your address via DM, just so that I can make sure I don't send it to the wrong place?

Thanks

Akiba

Hi Phil.

A replacement board was just sent out to you. Thanks for your help with the pictures and the patience :)

Akiba

Hi Akiba,
Yes, the TSL2591 has an interrupt pin and there are also a couple of example applications in the Adafruit and TSL2591MI libraries. I am doing tests making the connections with Dupont cables in the I2C connector of the Wildlogger, and for the interruption I will use the corresponding pin of the PIR connector
The connections do not concern me since, once the prototype has been tested and defined, my idea would be to make the maximum of welded connections to avoid failures
I'm still in the design phase, I already have the hardware quite defined, and now I have to enter with the most difficult part, the software, which for me is where I have the most difficulty
I have been gathering the elements to prepare the cake, and now is the time to enter the kitchen, I will not deny that I am excited and terrified at the same time
I'm already telling you ...
Regards !

I appreciate your encouragement !

Don't hesitate that I will keep you informed of the progress that I am making

Happy weekend !

Hi Akiba,
Oh, your answer is great!
My idea is to build a DL that allows,

• Light registration, with time stamp, when it exceeds a certain threshold (To control the human presence in the cave) The card only has to record when this threshold is exceeded to save energy
• Periodic record of temperature and humidity
• Data recording on SD
• Autonomy of at least 4 months

I have tried some sensors and I think I will use the TSL2591 because it has a very low detection threshold (0.18 uLux) and has an interrupt pin. I've already been testing some sample libraries, and I think it would be ideal
For temperature and humidity I am hesitating between using the DHT11 or the BME280
Perfect the external reference of the ADC if it serves to have more accurate readings
My idea is to use a power bank with 3 or 4 18650 Lipo batteries and built-in BCP, and to be able to disconnect the device when it detects that the power supply is less than 3.2V
Is the Sandisk card you mention a normal one, or of an industrial type like the one you presented in the corresponding module?
My best wishes,

Oh that sounds like a fascinating application. I've actually just started a thread for Wildlogger add-on board requests. The TSL25911 sounds do-able and also it looks like one useful thing would be to put together some adapter cables to other popular modular systems like the Adafruit Stemma and Seeed Grove. Let's discuss this in the other thread. 

Hi JAL.

For Module 3.4 - Lab 4a, the time will be hard coded into the sketch and then it will just print that time out. It's just to demonstrate how you would set it and how you would print it out. Every time you reset the board, the same time is reprogrammed into the real time clock so it will never advance. 

Where you will see the actual real time clock behavior is in Module 3.4 - Lab 4b where you set the clock from the command line and can read it from the command line. Since it won't be hard coded but rather set at run-time, and then independently read out, you should see the clock advance. Also you should only need to set the clock once as long as the backup battery holds up (should be good for a few months to years). 

Please try lab 4b and check if the clock can advance. You should see the seconds incrementing at least.

Akiba

Hi Akiba!
Now it's okay, and the clock is ticking!
Now I understand the errors I made, I had used the example of the Rtc_Pcf8563 "Setclock" library that contains in the Setup an "rtc.initclock" statement, with which every time you restart the program the clock starts counting from the starting point of departure.
Your first example did not set the clock either, and it only served to enter a time and print it later.
I had also tried to use the Rtc by Makuna library to automatically synchronize the time of the PC with that of the RTC, but I got a time loss error, as if, for some reason, the RTC did not retain the time. It is true that this library is designed for other RTC models of the DS **** series, and surely the error comes for that reason
Do you know if there is a library to fulfill this function with your RTC?
Thank you !!

Too many things to consider! :-)

This is one of the reasons why I try to work with VsCode, that this IDE allows to save each project with its library versions

But I still have other problems that I do not understand ..., we will continue to insist

The great advantage of this course is your professional support, without it we would be lost!

Best regards !

Oh great. That makes me feel better also. Hope you have a stable development system to work off of. Great things still need to be made!

Akiba

Ha ha ha. it will be much more important than that later on. 

Stay tuned :)

Akiba

Hi Liam. 

To get the cables through the cable gland, we'll need to remove the wires from the terminal housing and then reinstall them. That will be in a later module.

Akiba

Hi Akiba, Jacinta,

Jjust to say I've complted all the videos through to end of 3.3.1b successfully - no problems!  It snowed here in the North of England last night, so was measuring temperature today!

Many thanks

Rob

Hi Everyone.

Just thought I'd add this to the list, as I have found it very useful.

Practical Electronics for Inventors by Paul Scherz and Simon Monk. (ISBN 978-1-25-958754-2)

It does the "high level" stuff and the detailed stuff very well and covers a lot of the devices and functions you may think of using in a project.

Cheers

Sean

Hi everyone,
while beeing separated from my Wildlogger board I still had to play with some sensors ;-)
Ceck out this wonderful project: https://sensebox.de/en/
Great to learn coding with this nice blockly interface:

I had lots of fun monitoring the particulate matter influx from the illegal fireworks ;-)

Greetings from Austria,

Just saw this in the digest listing -- I'd hit the same problem with the WiFi SD cards being power hungry so we're developing something ourselves with Bluetooth, WIFI and LoRa. Currently pursuing funding to be able to develop it faster, but the intention is to opensource -- so would love to colaborate if anyone has interest/input/use cases? My PhD is in low power wireless sensor networks so nice to have a project it can actually be useful for. Providing we can get funding we'll have some 'free to you' prototypes for field testing.

Hi @openlx 

Sounds very interesting and love to hear more. So would your system work as a replacement SD card, or work with an existing card/card holder. I think there's a lot of potential for any conservation technology that uses SD cards, including camera traps. And can I ask what sort of ballpark levels of funding are we talking? 

Cheers,

Rob

It would slot in to replace the usual SD storage card, with power, controls and antenna etc. hanging off thin wires -- the idea being to fit as many existing products as possible. Looking to raise about £10k for the proof of concept and then same again for certification and initial run.
