LR24 Thermistor upgrade

Afbeelding
Tije de Jong performs the upgrade from pressostat to thermistor controlling the boiler temp/pressure in the LONDINIUM LR24 machine. No 'clicking' of the big pressostat anymore ;-) As of now all LR24 will come with the thermistor pre-installed.  

Circle cutter coffee

Bob vG sent me a circle cutter and coffee filters so I could try adding a filter to my espresso extraction. Using the same (natural processed) Brazilian beans, the filtered extraction is mild and amplifies the fruity character, whereas the unfiltered espresso tastes more spicy.  

Slappe Bak

A friend tells me she does not like espresso so much, preferring a weaker brew which is in Dutch a 'slappe bak' so I use the ETZmax to grind Brazilian beans, the LONDINIUM LR24 to extract an espresso and the Fellow Corvo EKG kettle to dilute it with water that's kept at exactly 65ºC so the 'slappe bak' is not burned and just hot enough to drink right away.      

G-IOTA & LR24

A simple procedure to make oneself a single dosed cup of coffee, using the G-IOTA grinder and the LONDINIUM R24 espresso machine. This G-IOTA needs to be set very fine, a little below the "zero" point even and the grinding takes relatively long (37s) but then, at 18g in the 18g basket, a nice flow delivered a delicious sweet early morning espresso. This procedure would fit well with home baristas who enjoy all the extended rituals of weighing the beans, watching the grinder munch away with a spray of grinds at the start and a long breath of grind dust at the end to finish off the last few beans, weighing again, shaking, stirring, tamping...  I mostly just push a button on one of the other grinders, get 18g in a few seconds, stir, tamp, lock in and extract, but the LR24 espresso from the G-IOTA grinds was impeccable so I'm sure people who choose the G-IOTA for its low price will be happy.

Sputnik3 VFD test

Jan came over from Friesland and brought along a VFD drive which also emulates three phase power so the fan has more power. Before, we used a large capacitor to provide a 'third phase push'.  

Fellow Corvo EKG - fun smart small water heater

  Bought this little black water kettle at a big online store. The confirmation email said it could be a week before delivery but the very next day a young man was at my door for delivery!  Wouter Brunia of https://wb.coffee/about works here in Amsterdam so it was easier for him to hand deliver than go therough the trouble of shipping ;-) The kettle heats to a precise target and then keeps the water at that temperature. I like to drink hot water of 65ºC and until now I just cooked water, poured it into a thermos flask and added some cold water. Now I always have water of the temp that I like ready to pour into my glass. And when I next go on a trip I will bring it along to make espresso with the Mypressi and then I will set it to 100ºC to properly pre-heat the device. Here the water is 100º and I turned back the target to 90ºC Here water is heated 100ºC and on hold to sustain the temp. I compared water from my BWT water filter system to the water provided by the city water company and
