Lusso group working day

-

6 0'clock, the web switch turns on the Lusso and after a few minutes the group begins to warm up. An hour later the group has reached the 66/67º C mark which it will keep most of the day.



Measurements taken every 15 seconds, hence the block-like graph. Shortly after 9am I make a first espresso and the group warms up to 70º C. Using the laser beam I see the coffee leaving the basket going from 60º quickly climbing to 65º and rising slowly, when the flow gets going, to briefly touch 70º and than lower again towards the end of the extraction.

The second time I first pre-heat the cup softly flushing the group. I could better use the tea water tap for that, but it's no problem.


A full working day for the Lusso. Notice the relatively quick warm up time of an hour and the long time, about 11 hours, it takes for the practically empty boiler to completely cool off to room temperature. The spike before the cool off starts is caused by my flushing the group to clean it and empty the boiler.

Finished Pavoni & Fuji PXG4 pid: Probe Inside the Ring

Delicious cup: all the work was well invested! At the end of the previous blog about the pressostat and PID working together , I mentioned that I would like to clean up the xmas tree of wires and have as few cables and probes as possible to visually disturb the classic design of the La Pavoni. Getting rid of the probe that was fastened with copper tape to the top of the brew group was a priority. I wanted to hide a new probe in the cooling fin as close as possible to the brew group. This morning I asked Tije if he could do that. He would need to drill a straight hole of 3mm diameter in the 4mm inner ring of the cooling fin that sits as a tight clamp around the brew group. Always the optimist, Tije set to work: First, Tije made a piece of aluminum to fit the inside of the ring. Drilling a thin hole straight through the curved aluminum, if possible tangentially going through the inside of the ring to touch the brew head directly, you need the support of the temporary insid...

KiwiSDR2 [radio]

  Despite selling one and giving away two of the five monster vintage 'boat anchor' receivers that I had, I still enjoy listening to shartwave radio. The modern iCOM R8600 that I also have has a wider range plus some decoding options but it's not easy to figure out what encoding is used on which frequencies. The SDR-Control app from Marcus Roskosch at https://ham-radio-apps.com/ makes this much easier and also allows some remote control of the receiver so you can place it and an antenna at the top floor of your house while listening downstairs. I also got the SDRplay RSP1B box: This offers a great listening experience at a very low price compared to the iCOM hardware. I had one before and bought one again after a (somewhat limited) Mac version of the software became available. This device needs a computer to be connected to the receiver. For some time now a nifty little device has appeared which not only works standalone, it even allows you or anyone else to utilize the ...

Tiny Cheap Fluid Bed Roaster by Tije and Jan

(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics.  On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the...
