After almost a year with 2 set of EC155 (at home & office),
I’m very interested about adding PID myself.
Currently I’m researching methods by using Arduino,
until I found your site with similar ideas!

While I’ll continuing my study (at a primitive stage…),
I’m more happy to be advise for your kits availability!
Please keep me informed for any good news!

Regards,

Noel

Comment on Arduino Leonardo – Interrupts by Ethan Zonca

I’ve “hacked” SoftwareSerial into a working state, but it’s not pretty. Basically you have to add an attachInterrupt(myRxPin, myTestISR, CHANGE) call in your setup() which calls an ISR you write. The ISR you write should call mySoftwareSerialInstance.recv() which I made public. Nasty, but it works. Let me know if you try it out / have any better ideas. I couldn’t get attachInterrupt() to work on a method of a class, which is why I’m doing it externally.

Hi,
Is there any update or ETA for softwareserial with the Leonardo? Thanks.

Hey Seth, I’ll probably get the source up in my repository in the next couple of weeks. I have an updated sketch with an OSC interface for control from an Android phone as well as some other improvements.

I would like to play that processing sketch. Are you planning on open-sourcing it?

Comment on Depressurizing the EC155 Portafilter by meowwl

I’d add that if you’re having trouble with it entirely depressurized, you can partly depressurize it by weakening the spring. Just pop it apart via the “permanent” method, get some heavy duty wire cutters, and clip off a coil on the smaller end, and reassemble. It cuts the backpressure by about 25%, and makes for a slightly drier puck.

The advantage is that you can use a coarser grind (Like if you’re stuck using a storebought pre-ground coffee, rather than grinding your own.) than you should for espresso, and still come out with a decent shot.

If the coffee comes out right away, then chances are it’s either not ground fine enough, or not tamped enough. Just about any tamper other than the one actrually on the maching will work better….That thing bends rather alarmingly if you try to tamp it down properly.

Was actually looking for something like this for my account on the school engineering computers. Pretty freaking sweet.

Scott–I’ll let you know when the first run of boards are available, which should be in the next couple of months.
