Music by Ludovico Einaudi, pianist Jeroen van Veen. And you could lie down in the big “Werkspoorkathedraal” in Utrecht.
Ludovico Maria Enrico Einaudi (Italian: born 23 November 1955) is an Italian pianist and composer. Trained at the Conservatorio Verdi in Milan, Einaudi began his career as a classical composer, later incorporating other styles and genres such as pop, rock, folk, and world music.
Einaudi has composed the scores for a number of films and television productions, including This Is England, The Intouchables, I’m Still Here, the TV miniseries Doctor Zhivago, and Acquario (1996), Nomadland and The Father.
He has also released a number of solo albums for piano and other instruments, notably I Giorni in 2001, Nightbook in 2009, and In a Time Lapse in 2013.
Coline plays some of Einaudi on keyboard, and we play I Giorni with our Folkband.
We love fermenting! Sometimes we ferment our own sauerkraut.
Depending on the volume it can take at least 2 weeks up to several months.
Bottom left – Stone Crock pot weights
If you don’t have crock pot weights, use a plastic bag filled with water. (See below)
Mixture: Salt, juniper berries, dill, celery seeds and caraway.
Rinse Cabbage and clean. Cut out and discard the hard white center.
Take the largest leaves from one cabbage and lay them out at the bottom of your clean and rinsed out crock pot.
Shred the rest of the cabbage.
Add a layer of shredded cabbage over the laid out leaves in the crock pot. Sprinkle some of above mixture over this layer. Compress by stomping down with the stomper.
Repeat the layering process until you used up all the cabbage, salt, and juniper berries. After each layer stomp it down.
Pour all the luke warm water over the cabbage. That will activate the fermentation process.
Place clean crock pot weights over the cabbage and close the crock pot with the lid. Pour water into the ring of your crock pot and make sure there is always water in that.
Wait several weeks until cabbage is done fermenting into Sauerkraut.
While on holiday in New Zealand i made photos of a rock i found on the campsite we where. Nothing special about the rock, but it was a nice subject to try to replicate.
So i took many many pictures of the stone from all sides.
Imported those images in meshroom and convered it to a 3D stl object.
For measuring pressure in fermentation containers, I designed a pressure sensor which could be wireless connected to a fermentation container. The sensor would transmit the values to a Raspberry which was configured as a Access Point and would store the measurements and generated graphs using Grafana.
Connect esp with a power source. Look for a AP with ESP_Easy_0
Use password “configesp” to connect
Start you browser and enter http://192.168.4.1
In wifi wizard setup select “pressurespot” Enter password “pressurespot”
Press connect
Wait 20s and look in the raspberry logs which IP the ESP got.
Connect laptop/mobile to wifi “pressurespot”and connect
Enter found IP from ESP in your browser.
Proceed to main config
Main setting table, set the following
Unit name & number + append
SSID and WPA key pressurespot
Client IP block level allow all
Press submit
Press controller tab
Press first edit button and set following – Protocol: domoticz http Next set – Controller IP : 10.42.0.1 – Toggle enabled and press submit
Resulting in:
Next we got to Hardware
I2C interface switch GPIO-4 and GPIO-5
GPIO – SDA: GPIO-4 (D2) change to GPIO-5 (D1)
GPIO – SCL: GPIO-5 (D1) change to GPIO-4 (D2)
Press “Submit”
Devices TAB
Press edit, and select device “Environment – BMx280” from the pulldown menu.
Next, set the following
Name: pressure
Enable on
I2C address : 0x76 ( Is there is no 0x76 of 0x77 .. do a i2c scan on the next tab )
Send to controller , mark this
IDX: give this the number you had given this node (this is the one you have to use in domoticz )
interval 10Seconds
and press submit
In the Devices tab, you should be able to see the sensor with the values (Temperature and pressure)
No values? Do a i2c scan and/or reboot ESP ( You can find these in the tools tab)
Tools TAB
Press I2C scan, when seeing a address like 0x76 or 0x77 use this in previous tabs. Still nothing, even after reboot? Maybe faulty hardware?
Everything okay? Back to the config tab
We are going to set the sleep mode. Warning ! .. when setting this it is hard to get into the config pages again. ESP will startup, connect to wifi, send values and goes to sleep again.
At the bottom set: Sleep awake time 1 sec
Buttons on the raspberry / pressurespot
Red button :
Less than 3 seconds is reboot
Longer than 3 seconds is shut down
Charger can be removed, when the green light is off
Led lights on the sensors
Red light (R2; constant): battery is charging
Blue light (R1; constant): battery is full
Blue light (R1; constant) & red light (R2; blinking): trying to charge, but no battery connected
Add shutdown script to /etc/rc.local
python /usr/local/bin/power-switch.py &
/usr/local/bin/power-switch.py
#!/usr/bin/python
import threading, subprocess
import RPi.GPIO as GPIO
def shutdown():
subprocess.call('sudo shutdown -h now', shell=True)
def edge_detected(pin):
if GPIO.input(pin):
t.cancel()
subprocess.call('sudo reboot', shell=True)
else:
t.start()
if __name__ == '__main__':
try:
GPIO.setmode(GPIO.BOARD)
GPIO.setup(5, GPIO.IN)
GPIO.add_event_detect(5, GPIO.BOTH, callback=edge_detected, bouncetime=10)
t = threading.Timer(3.0, shutdown)
while True:
pass
finally:
GPIO.cleanup()
/usr/local/bin/ledoff.py
#!/usr/bin/python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(18,GPIO.OUT)
GPIO.output(18,GPIO.LOW)
/usr/local/bin/ledon.py
#!/usr/bin/python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(18,GPIO.OUT)
GPIO.output(18,GPIO.HIGH)
Now we can check that grafana is up by loading it in a browser: http://10.42.0.1:3000. If so, you can log in with the username and password = admin and set a new admin password.
