It's designed for Water Displacement, and it's more like a lacquer. As it ages, it gets really gummy. <BR/>http://www.google.com/search?q=wd-40+gummy+lubricant&sourceid=navclient-ff&ie=UTF-8&rlz=1B3GGGL_en___US215Sysadmnhttp://www.blogger.com/profile/09208769396923431693noreply@blogger.comtag:blogger.com,1999:blog-18025058.post-61220071101360236612007-09-10T02:12:00.000-05:002007-09-10T02:12:00.000-05:00wath a beautiful idea! <BR/>but which kind of coffe you use? here in Italy I can find some of best and optimal quality, but them in America? it is possible to find them?<BR/><BR/>btw, nice work! ^_^<BR/><BR/>=nil=Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-18025058.post-52605989932801814662007-08-17T22:07:00.000-05:002007-08-17T22:07:00.000-05:00Tim, I have some questions about how to use my PID. <BR/><BR/>Can you drop me an email?<BR/><BR/>Dougwamble at g mail<BR/><BR/>Much appreciated if you have a moment...DWhttp://www.blogger.com/profile/03730506258563565316noreply@blogger.comtag:blogger.com,1999:blog-18025058.post-38232853262614242007-05-14T11:26:00.000-05:002007-05-14T11:26:00.000-05:00props to that<BR/><BR/>www.the-ultimate-solution.net<BR/><BR/><A HREF="http://www.the-ultimate-solution.net" REL="nofollow">Get Rich Quick Home Business Scams</A>Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-18025058.post-33445269570632254942007-05-12T21:42:00.000-05:002007-05-12T21:42:00.000-05:00You are mad, truly mad.

Thanks for the lubrication tips as well! erik, you are right on about running a little web server in there with saved performance data and a web interface for tuning. one of the rabbit semiconductor board would be great for that.<br /><br />dan b. I am far from an expert on temperature sensing. In fact, I picked this device because it gives you temp readings in the easily digestible 0.1 volts / degree. I had a moment about whether I should be using a thermocouple , but my friend casey (who is much better than I am this kind of stuff) said it was pretty much gonna be the same thing. While drilling the boiler makes a little sense for speed (though, once the thermostats are gone, are people using those tapped holes instead?) the whole system in inherently slow. Seems like splitting hairs for temp sensing. When you pull a shot, its gonna take a few minutes to get settled back with the stock heating element. Whats the hurry? ;) Also, I am taking thousands of measurements and averaging them, which I think de-noises the sensor quite a bit. <br /><br />preinfusion? I gotta google that, but it sounds cool. If it takes what you describe, then yeah, <br />it would be no problem.<br /><br />oh yeah, in terms of drawings and stuff. I'll have to see if I have anything useful. I really stumbled my way through this (it really did take years to complete), and broke a bunch of stuff on the way. One thing that was really helpful, the drawings and schematics here: http://www.espressotec.com/ummanual.asp#rancilioparts<br /><br />i studied that schematic with a beer for countless evenings to figure it out, but it was vital.Tim Hirzelhttp://www.blogger.com/profile/01455788234007245234noreply@blogger.comtag:blogger.com,1999:blog-18025058.post-69264917486149801022006-12-05T16:20:00.000-05:002006-12-05T16:20:00.000-05:00very cool, i just started planning a pic pid myself the past couple weeks, so i'm psyched to find this. couple thoughts: how accurate do you think the lm34 is? everyone now seems to be sold on tapping the boiler and using type t tc's for speed and accuracy. <br /><br />also, seems like you could add preinfusion pretty easily by opening the solenoid and delaying the pump. yesno?dan bnoreply@blogger.comtag:blogger.com,1999:blog-18025058.post-16170715010629373432006-12-05T13:29:00.000-05:002006-12-05T13:29:00.000-05:00A good food-grade lubricant is <a href="http://www.super-lube.com/">super lube</a>. I have run the mistake of using wd-40 (actually someone else did it before I could stop them) and it is a horrid mess on food appliances. It not only tastes awful but penetrates many metal surfaces so it is really hard to get out. Don't do it.<br /><br />BTW, the mod is fantastic. All you need now is a tcp/ip stack, an ethernet port and a webserver.erikhttp://www.blogger.com/profile/00767364624294293659noreply@blogger.comtag:blogger.com,1999:blog-18025058.post-68461582009513450922006-12-04T22:43:00.000-05:002006-12-04T22:43:00.000-05:00Fantastic job mate!Adrianhttp://www.blogger.com/profile/09647700646998995561noreply@blogger.comtag:blogger.com,1999:blog-18025058.post-57607807059893379172006-12-04T16:41:00.000-05:002006-12-04T16:41:00.000-05:00Wow!

Simply put it onto the end of a q-tip and swab it where it needs to go.Alexanderhttp://www.blogger.com/profile/06350279458843176325noreply@blogger.comtag:blogger.com,1999:blog-18025058.post-39514539299594984062006-12-04T05:40:00.000-05:002006-12-04T05:40:00.000-05:00Hi Tim - you've made a really, really nice job there.
