Weekend baking – bagels

I have found it difficult to find bagels that I like in California. I’m not sure what’s different about them, but my preference is for a bagel that is a little crispy on the outside and chewy on the inside. For sure, I’ve not been to every bakery and bagel shop, but who really has […]

Smart espresso machine

Espresso machine controller is now installed in the electronics drawer! I’ve posted a few updated videos demonstrating the basic functionality. I’m considering the hardware complete at this point, however I’ll probably be continuing to add software functionality.

TWI debugging

I’ve spent the evening trying to get the espresso controller and the WiFi controller talking to each other. I’ve been very thankful to have my Siglent digital oscilloscope that my good friend Taufan bought me for Christmas one year. He also had the good taste to include the serial decoding license (which is very handy […]

Assembled espresso controller

This has kept me busy all morning and was either a lot of fun, or the funes from the rosin-core solder have been getting to me… I assembled my espresso controller and gave it the first power on and it seems to work marvelously! While testing it, I’ve made a few notes and discovered a […]

Faema Controller PCBs arrived

Happy new year! Last year (beginning of December) I had sent out my designs for my Faema controller boards to pcbs.io a few weeks back and they finally came today! I knew it would be a couple of weeks so I had them delivered to my parents house in northern New York where I am […]

Faema Controller v1

I’ve finally created a full controller schematic for my Faema Special in KiCad. In typical fashion, I’ve added lots of extra features that are probably unnecessary, but I want them the same! Being that a lot of it is software in the microcontroller, I’ll continue to add features, but here is what it does in […]

If I only had a brain…

So, I’m not sure if anyone has noticed that in the previous pictures (all of them) one of the main components that my machine has been missing since I bought it is the main rotary switch. You can see in the first picture there’s just a hole where the switch was, and the neon lamp […]

Faema Special, Installed

I decided I couldn’t wait to set up the Faema Special in my kitchen now that it was painted and looking nice. To do this, it’ll need a 2-phase (240VAC) power source, a water source and a drain. To power the machine, I’ve split the power for my kitchen range using a custom splitter that […]

Alfa Red

I finally decided it was time to give the machine some fresh colors. It was a red color before and I wanted to keep it the same. I ended up selecting a color from the PPG auto finishes catalog that is an Alfa Romeo red. I forget the exact name of the color, but it’s […]

Machine reassembly

I finally got the machine reassembled, except for the cosmetic panels (which still look faded and oxidized). Repaired the level control board (with stuck relay). I discovered that it energized the boiler fill valve continuously as long as the machine had power. The video posted is of the first shot drawn on this machine for […]
