But, like many things... there is a time to move on. My espresso interest has taken me to a new commercial machine, and so it's time to say "good bye" to Silvia.
Because none of the original electrical wiring needed to be cut for the Arduino modification (I used quick connectors for everything) returning Silvia to her virgin form was very quick and easy. In fact, I was amazed at how little time it took to undo compared to all the hours it took to do! Once completed, of course I had to test her out...
Actually tasted as good as it looks!
I have photos of Silvia, in her new form posted on Flickr, and you can see the photos here. There is also a slide show of the images.
The only modifications that I left behind are the following:
- Brew pressure adjusted to 8.5 bar
- SSR retained for future PID installation - if desired
- Dispersion screen - countersunk / flat head screw
- Insulation remains on the internal steam tube (looks cool!)
