universam1 / ispindel Goto Github PK

Can anyone shed any light on whats happening here please.
I've tried every possible combination of service type & tried to connect to different networks with correct lowercase passwords. Also swapped the 470 resistor for the BAT43, but the error msg below remains the same.
I found it odd that the Wifi BasicClient sketch connected to the network just fine
Any insight would be much appreciated

Why don't use built in GY521 (MPU6050) temperature sensor ?

This url has been out of stock for a long time now, and they don't reply to mail, at least not english mail it seems, http://cachers-world.de/de/Petling-XL

Perhaps you could throw up links to some other blessed containers?

Running Firmware 3.4.4 on a bare (not connected) Wemos D1 Mini powered by my PC to test before final assembly.
The firmware loads and runs, I can see the first data pushed to Ubidots OK, but then nothing ever again.
Checking the serial output via Arduino 1.8.2 desktop app is see the following, the sleep at the end catches my eye. If thats correct it sleeping for 41,666 days

Servus,

mit welchem CAD wurde der Schlitten erstellt (Inventor, Catia,...?). Wäre es möglich, die CAD Datei - und nicht nur die STL Datei - zu veröffentlichen. Ich würde den Schlitten gerne um einen Clips für die Batterie erweitern. Dann braucht man keinen Kabelbinder (der immer anders sitzt) und die Messungen sind vergleichbarer.

Selbstverständlich würde ich meine Revision zur Verfügung stellen!

Viele Grüße,
Bernhard

PS: Gibt's nen Zeitplan, wann der Code online kommt?

Hi,

I'm interested in building your project, but you only release compiled BIN files. Do you plan on sharing the source code so one can learn from the code and alter the code for it's own needs?

MPU 6050 has a temperature drift that needs to be compensated

I can make a connection to my RPi using TCP. I've got that working, but using the craftbeerpi setting it is not working. I build the firmware using Arduino 1.8.1 on Linux (Elementary OS). iSpindel is latest pull from github.

I tried to configure from a tablet, laptop and smartphone. No success. Same error. TCP works fine.

Hi,
I would like to send my data to splunk.
in splunk the token has to be set in the header, like in this curl request:
curl -k https://localhost:8088/services/collector/event -H "Authorization: Splunk B5A79AAD-D822-46CC-80D1-819F80D7BFB0" -d '{"event": "hello world"}'
would it be possible to add a header var to the generic http call?

regards,
-thomas

While saving configuration the program would crash with following stacktrace:

This translates to:

The error causes the board to reset and configuration is not saved. I observed it only in combination with WiFi functionality.

I use Amica ESP8266 NodeMCU 1.0 board connected via USB without a temperature probe or any other devices connected. The stacktrace varies, but it always happens in ets_timer_disarm routine. I looked at what is running in timer, and it was the flash function calling getTemperature() amongst the others. And there there is a delay(200). I am not sure about the reason for this delay. Perhaps a minimal waiting time before DS boots up. But if I remove it completely or reduce to 100ms, the error is not being reproduced and configuration is changed.

I understand that I don't use D1 mini, but they are the same chip. Also, I don't have temperature probe connected which probably causes the problem. But apparently there is an unfortunate combination of events that causes that and prevents from tinkering around with the code.

Proposed pull request: #49

Upd.: I'm reading the internet on those delays now, and it seems to me that those may actually be required for assuring a certain state of peripherals. Perhaps some sort of a small state machine could be an option instead of explicit delay.

Hi,

I'm trying to find a suitable resistor for the 230K one, but it isn't a common value. Can I use another value like 229K or 232K ?

Hi, Great project!

I'm attempting to load iSpindel onto a Wemos D1 mini barebones i.e. no sensors etc connected. Just to have a "play".

I can compile and upload the code but when I attempt to configure the Wifi settings then the s/w raises an exception and restarts the device.

I get the following serial output when I attempt to save the config data in the browser.

Any thoughts ?

I'm using Arduino IDE v1.6.13 with ESP8266 board manager 2.3.0.

Thanks.

You mentioned a Win-tool for flashing Wemos.
I only have a Mac on my site. What will the right tool for flashing?
I tried Arduino IDE, but git a cimpilation error:

In the documentation there is link to http://cachers-world.de/en/Petling-XL which is not available at the vendor. Consider refering to products that are available.

I'm new to 3d printing, what material is best for the sled/drawer?

Hi

Any idea why my ispindle show 5.338895V ?

I have assambled one where voltage goes down after usage as it should, but this one still display 5.338895 v after 12 hours usage with submit every 15 sec?

Unsure what infill I should use, or if should be solid?

I can't find any pet preform like as suggested in my country, is there some place to buy one ( like ebay, aliexpress, etc) ?

is secure use another size/shape?

thanks.

Is there any plan to create FG.php instead of Plato.php or is there any optio to transform Plato to FG in php file?

I build one unit with my friend and then when I arrived at my house I tried to configure my home wifi network, each time I try to save it's refusing to save. it.
any suggestions?

Not an issue, just to say that https://monitor.beer now support iSpindel 100%, you can now have full control during fermentation. No longer need for creating your own graphs etc. Just register, get three months free and if you like it pay a small monthly amount to continue using https://monitor.beer.

Continuous alcohol%.
Continuous yeast attenuation%.
Continuous fermentation%.
Continuous temperature.
Ongoing SG.
How long SG is stable in days.
Minimum temperature through fermentation.
Average temperature through fermentation.
Maximum temperature through fermentation.
Number of days fermentation.

There is a small issue in the FHEM config documentation in file docs/upload FHEM.md:

The line
return $cPlato;
in method CorrectPlato()
should be changed to
return $mPlato-$cPlato/100;

Thanx
Martin

Hi,
Can you provide the dimensions (size and volume) of the Pelting XL? The website doesn't have them in stock and I was hoping to source from somewhere else. If I find a suitable replacement I'll help add it to your documentation.

Hi,

Thanks for a really great project.

I do not get how the vfact variable is used.

Does analogRead(A0); not give a value from 0 to 1023, referenced to 3.2 V?

float getBattery() {
analogRead(A0); // drop first read
return analogRead(A0) / my_vfact; Could you explain how this work?
//return analogRead(A0) * (3.2 / 1023.0) * divider ratio(5.5); Is it not this?
}

The divider ratio is based on the diagram with the extra 230 k Ohm from Vcc to A0.

Hi, I used my spindel for the first time in a brew last two weeks.
Now my voltage indicator in ubidots stayed all the two weeks at 4,45V when i measured it at the end of fermentation it was 3,70 V. What can i do to get ubidots to read the right voltage ?

Regards Willem

I have been troubleshooting my temperature reading as it was 5 degrees too warm and after replacing the temperature sensor a few times (three times, one from another supplier plus I have re-soldered the whole board) I figured out that the sensors is a parasitic power only version... Is there any chance you could add support for this version in your code?

Thanks

Add a README.md to explain the purpose of the different drawer designs found here:

https://github.com/universam1/iSpindel/tree/master/drawer

Drawer-cachersworldXLv12.stl has a version number, and the highest, but Drawer-combo-short.stl was most recently changed. They look slightly different while Drawer-cachersworldXLv12.stl and Drawer-cachersworldXLv11.stl are indistinguishable to me. Some description is in place.

It looks like the kit here:
https://3d-mechatronics.de/en/ispindel-diy-set-komplett_151.html

Has either Drawer-cachersworldXLv11.stl or Drawer-cachersworldXLv12.stl

Hi again,

One question about weight in the tube. What are you using for weight and how much?

Thanks.

Hi

I'm not a github expert, so I post my contribute here. It is php script there save data in a mysql database (instead of using the python script). It use the same database table use by the TCP example. Just insert db server, database name, user and password.

In the config of the i spindle set:

Save the below code as index.php and place it domain.com/beer/index.php and the it will recive the data from the ispindle and store it in the database.

`<?PHP

$inputJSON = file_get_contents('php://input');

$data = json_decode($inputJSON);

$date = date("Y-m-d H:i:s");

$servername = "XXXX";
$dbname = "XXXX";
$username = "XXXX";
$password = "XXXX";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO Data (Timestamp, Name, ID, Angle, Temperature, Battery, ResetFlag, Gravity)
VALUES ('". $date. "', '". $data->name ."', '". $data->ID ."','". $data->angle ."','". $data->temperature ."','". $data->battery ."','','". $data->gravity ."')";

if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "
" . $conn->error;
}

$conn->close();

?>`

Eine universelle Schnittstelle zum Datenaustausch soll festgelegt werden.

Variante 1:

• HTTP POST
• URL: http://<IP-Addresse>:<PORT>/api/spindel
• Body: JSON

{

temperature: 20.5, 
angle: 89.5, 
battery: 84
}

Hi,
Nice work with this brewing tool! Im just getting started and Im testing all functions.
How do you set a custom HTTP post url using the GenericHTTP function?

Im used to doing something like this: http://192.168.4.2/ispindel.php?SG=$SG&Temp=$Temp&Volt=$Volt

/Ted

"Connect Wemos USB + 5V (above diode pin) to Lipomodul + IN (optionally to load over the Wemos)" is unclear. Does this mean one side of the removed​ diode is to be connected to the lipo ? If so, which side ?

This wire is not shown on https://github.com/universam1/iSpindel/blob/master/docs/iSpindelbreadboard.md which is unfortunate, as my iSpindel is assembled without it :-)

Thank you for your help.

Benoit

I saw in the documents that somebody made a PCB specially for this project, is it possible to share the file and the method you made it?

From the pictures it seems the suggested battery does not come with a protection circuit.
Aside from having to change the drawer, is it ok to use a battery with protection circuit?

Is it possible to get more than 2 digits after dot?
There is a big difference between 1.06 and 1.07 in gravity calculation.

The new calibration tool doesn't work for me in both FF 55 and latest chrome. There seems to be a cross-domain code loading problem. When I open the page I get:

Laden von gemischten aktiven Inhalten "http://code.jquery.com/jquery.min.js" wurde blockiert.

Adding a second dataset I get (logically concerning the error above):

ReferenceError: $ is not defined

Hi,

Is there any way to disable DS18B20? I wan`t to use the temp sensores on my brewpiless instead.

Hi there,

Firstly wanted to say that you are doing an awesome job here. 👍

My iSpindle is setup with the Wemos D1 Mini PRO which works fine except, the iSpindle wouldn't wake up from deep sleep with the config as described in your Wiki. A quick google told me that this is a known issue with the Wemos in general (all models) and that replacing the 470 ohms resistor with a diode solves this issue.

" instead of experimenting with resistors and relying on the "it worked for me" value, it would be more technically correct to use a schottky diode (e.g. BAT43) to cleanly pull rst low without side effects when gpio16 is high.

p.s.: the cathode (ring) towards gpio16 ..."

It worked for me so thought id share and hopefully it works for others as well.

Cheers

Tcontrol should be supported as a backend.
Currently the communication required is a UDP frame.

The question @Zooms1 is, if the generic #3 HTTP approach would be possible to implement?

As we already discussed by email, I'd like to write a small, very basic Python script that receives the iSpindle's data over a TCP socket, without any higher-level application protocol such as http.
The goal is to have a dedicated platform independent server for the spindle, with minimum overhead and battery drain.

The first step will be to simply write the data to a CSV file on a network share for Excel import.
Later I want to expand the capabilities to include database support and perhaps some http server functionality for client-side data retrieval.
The source code will of course be made available (it's Python, anyway..).

In order to accomplish this, I suggest the spindle sends a JSON string in the already defined format to a configurable IP Address (host name resolution would be nice-to-have) and TCP port (I suggest 9501 as a default).
After the transmission, the connection could simply be closed by the spindle, or I implement some response (no problem), for example ASCII 6 (ACK), and ASCII 21 (NAK) in case the transmission failed for some reason, perhaps even triggering the spindle to retry for a defined number of times before giving up.

On my side, I'm fully open to suggestions. Whatever works best for you.

Thanks again for your hard work!

As mentioned here:
http://hobbybrauer.de/forum/viewtopic.php?p=224288#p224288

For the public server we are developing, an extra input field in the GenericTCP config section, representing a User Token in analogy to Ubidots would be nice-to-have.

The contents should be submitted within the JSON as an additional parameter in order to ensure backwards compatibility.

I have some problem with the firmware. I have a wemos d1 mini pro but every time i get this error

I also tried with older version but same thing happen. I flash it with -fs 4m and 16m. Same issue.

How can i do? Thanks!

My supplier sent me the wrong temperature chips, so instead of the DS18B20 I got the DS18S20. This sensor does not support setting the resolution but other than that it should work the same.
However, I'm getting the "OW disconnected" error, which means (i think) that the one wire protocol did not initialise correctly. I commented out the part where the resolution is set and rebuilt the software. I'm still getting the error though...

Do you think this is a hardware problem, or are there other parts of the code that need to be changed to also support the DS18S20 temperature sensor?

sudo systemctl deamon-reload
sudo insserv ispindle-srv
sudo service ispindle-srv start

should be:
sudo systemctl daemon-reload
sudo insserv ispindle-srv
sudo service ispindle-srv start

Das Config Menü (captive Portal) könnte einen Button zum Löschen der Historydaten bei UbiDots & Co. bekommen, damit man bei neuen Gärungen mit einem leeren Verlauf anfangen kann.
UbiDots stellt dafür z.B. eine DELETE API zur Verfügung.

Solved. Please delete.

Maybe for later on,
to put a led and sensor in the tube to monitor how clear the wash is.

none of the image links appear to be functioning on this page any more?
