HECTOR 9000

Minimal Requirements

- RaspberryPi 3
- Debian bases Linux (to use installscript)
- Python 3.8

Prepare Raspberry

Activate I2C:

sudo raspi-config 

Here go to “Interfacing Options” and Activate/Enable I2C

Install on RaspberryPi

First you have to clone the github repo of Hector

git clone https://github.com/H3c702/Hector9000.git

This repository doesn’t contain a frontent. To get the original Hector9000 frontend see:

https://github.com/H3c702/Hector9000WebUI

To start the Hector software first move into the directory:

cd Hector9000

Then run this command to setup all necessary tools:

./setup.sh

Or run it with the option “-c” to preset the mqtt preconfigure for the WebUI

./setup.sh -c

To start the software run:

./start.sh

Add Drinks

To add a new Drink you have to modify the drinks.py file and add a new item into the drink_list array formatted as followed:

{
    "name": "NAME OF DRINK",
    "recipe": [
        ("ingr", "INGREDIENT1", AMOUNT1),
        ("ingr", "INGREDIENT2", AMOUNT2)
    ]	
}

All strings in UPPERCASE are placeholders, all lowercase strings have to be used literally in the definition. The INGREDIENTx names are not cleartext but are identifiers referencing into the ingredients list below in the same file. The AMOUNTx values are numerical values of the corresponding ingredient’s amount in grams.

At the moment there are only some ingredients but feel free to put in some new. You can add them in src/Hector/conf/database.py . Or you can use the WebUI when it is implemented.

A future extension might allow multi-language UIs.

Add Ingredients

To edit the Ingredients that can be used you can edit the database.py or use the tool in the tools folder.

python3 Hector9000/tools/Editingredients.py

Assigning valves

The available ingredients are also moved to the db and can initial be edited in the databas.py or over the WEB UI in the future.

For the meantime you can use the script “SetValveIng.py”.

python3 Hector9000/tools/SetValveIng.py

Calibration of Loadcell

HOW TO CALCULATE THE REFFERENCE UNIT To set the reference unit to 1. Put 1kg on your sensor or anything you have and know exactly how much it weights. In this case, 92 is 1 gram because, with 1 as a reference unit I got numbers near 0 without any weight and I got numbers around 184000 when I added 2kg. So, according to the rule of thirds: If 2000 grams is 184000 then 1000 grams is 184000 / 2000 = 92.

After you have calculate your reference then go to Hector9000/conf/HectorConfig.py and set the

"hx711": {
    "ref": 2145  # REFERENCE VALUE
    }

Development on non-Hector hardware :

In the HectorServer.py you have to comment line :

#from HectorHardware import HectorHardware as Hector

and uncomment:

from HectorSimulator import HectorSimulator as Hector
