I gave up on using this chip for a similar application because of the ~10C error that self heating produced. Watch out for self heating effects on the 6675.

If I ever find any additional information I'll post it on your blog and at coffegeek, so we can all share the info. Cheers. Ethan, thank you so much for your quick reply, it’s been very helpful.

I've looked around a bit, but I haven't found anyone who's posted information on what tip/wand they used... I'll put more info up on my <a href="http://protofusion.org/wordpress/2010/04/delonghi-ec155-resources/" rel="nofollow">resources post</a> when I find it.

I'm also a bit new to espresso, so my answers to your questions might not be exactly correct :D The crema in espresso is dependent on many factors, but grind, tamp, freshness of beans, and temperature seem to influence it the most. I just created a <a href="http://protofusion.org/wordpress/2010/04/delonghi-ec155-resources/" rel="nofollow">post</a> on parts for the EC155, it should answer some of your questions. PID is used to regulate the temperature of your boiler (see the <a href="http://en.wikipedia.org/wiki/PID_controller" rel="nofollow">wikipedia</a> article for detailed info). It can help provide more consistent results, and provides another variable that you can change. Hey, thanks for reading.

I've seen on the internet, the following video: (http://www.youtube.com/watch?v=-Tu1Cim3HfU) where the poster clearly has managed to find a metal replacement, I've already asked him the same question, I'm waiting for him to answer. I've you ever find a solution, could you please post it? The actual plastic tip is very difficult to clean, and if it isn't done correctly the hole will get stuck with stale hardened milk, creating an erratic behaviour of the wand. Thanks again!

Is this right? b)The size of the machine's embedded tamper is 51mm, is this a standard size? I've bought by mistake a 49mm and it leaves too much space around the edges. Do you know where I could buy on the internet an adequate tamper? c)I see you're installing a PID on the machine. What is it used for? (I'm a complete newbie at this) Is is to measure the temperature of the water at the boiler? Thank you very much!
