About this 3D model

I read this blog from Scott - the "Seattle Food Geek" about his 75$ Sous vide heating immersion circulator, and wanted to make my own. http://seattlefoodgeek.com/2010/02/diy-sous-vide-heating-immersion-circulator-for-about-75/ Unfortunately for me, being in Europe, most of the linked shops either don't send overseas, charge horrendous freight prices and/or the import tax makes everything very expensive. The PID Originally Scott recommends using a JLD612 PID. Since that was unavailable on eBay, I bought a Sesto D1S (see parts list for full model no. and link) The Sestos is a cheap knock-off of Auber's standard PID, so don't waste your time reading the supplied manual. Download Aubers, it's virtually the same functionality, and they explain *everything* in detail. If you use some other type of PID, you have to be cautious of 2 things: 1) Get a PID with a "PT100" input. This is necessary to get 0.1 C accuracy (K-type sensors only do +/-1 C). Not a deal breaker, but precision is pretty important in Sous Vide so those 10ths do come in handy... 2) Get a PID with SSR output (Solid State Relay). The built in relay of other/cheaper PID's will not be able to handle the current needed to drive heaters. If you do get one by accident, you have to drive a bigger relay with the built in one and you have to modify my schematics. EBay suggestions: PID bought from http://stores.ebay.com/MixTea ( Important! MixTea has lots of different PID's. Get the "D1S-VR-220" as this is the model with SSR-output.)
