Noch ein Nachtrag aus meinem Projekte-Ordner: Der PID Umbau meiner Rancillio Silvia auf clevercoffee.de/
Statt des Metallfilmthermostats wird die Temperatur jetzt digital gemessen und ist wesentlich genauer. Die Maschine heizt dann genau auf die Zieltemperatur.
Das ganze könnte man noch um diverse Module erweitern.

Meine Siebträgermaschine, man sieht ein kleines Display, das die Temperatur anzeigt. Im Hintergrund diverse okkulte Geräte zur Herstellung von Kaffee: ein Tamper, ein 3d-gedrucktes WDT Tool (zum Verteilen des Mehls im Sieb), eine Mühle mit Single-Dosing-Aufsatz usw.Die Innereien einer Kaffeemaschine und um etliche Kabel ergänzt. Neben den original-Bauteilen Boiler, Pumpe und Timer-Steuerung sieht man ein Solid-State-Relais, einen Mikrocontroller und ein Netzteil.Die Oberseite des Boilers mit neuem Thermometer. Das Bauteil wird einfach mit einer Schraube gegen die originale Thermostat-Halterung verspannt. Zwischen Thermometer und Kessel ist etwas Wärmeleitpaste zu sehen. Außerdem viele Kabel.

New PCB, new #3Dprinted parts... More wires and cable management...

Bottom View:
Self designed bracket with integrated cable holders which is screwed in the electronic box so that it can be easily removed without damage.

Back view:
self designed electronic box with the #CleverCoffee PCB installed and wired for PID only. Also, visible in the background, a modified #Wago holder.

Top view open: wiring of the machine with the additional cables for the PID and display.

Top view: Top cover installed with the new display holder. I've modified it pretty much... added a bottom plate which is screwed on the top part (original) with an integrated magnet to hold it in place. The original was only the top frame and should be glued on the cover with double faced tape...

Underside of the Rancilio Silvia espresso machine 3D printed bracket with integrated cable holder for the SSR live wires. The bracket is for mounting the electronic box on the inside.View to the backside of the Rancilio Silvia espresso machine without the casing. The open electronic box is visible in the foreground with the CleverCoffee PCB mounted inside.Top view of the open espresso machine, with all the cables installed for the PID controller.Top view of the espresso machine with the top cover installed and the new 3d printed display holder in the corner. Also, visible how deformed the round corner of the espresso machine is (bad packaging and probably dropped a view times by the delivery guy)

Okay, it's a while since the last post in the thread about the rebuild of a #Rancilio Miss #Silvia #Espresso machine.

If you haven't seen it yet it's over there

In the meanwhile I was busy collecting parts & building a prototype board for a existing project we'll want to use as a base for our modification: #CleverCoffee github.com/rancilio-pid/clever

Had it running for 6h and it holded the temperature perfectly (+- 0.5°C)

Also printed a basic case for the prototype to install it beside @ghostbear2k's machine.

Prototype of Clevercoffee on perfboard. Holded by a soldering '3rd hand' with a small oled display showing the current and target temperature of the PID. In the background is the rancilio Silvia espresso machine visible.Graph from the controllers websites which show a pretty stable temperature curve over 6 hours.Narrow basic case printed in black pla. The small oled display showing the deactivated pid screen from CleverCoffee
