Hi rock stars, Many thanks to the thoughtful, smart suggestions in Name that component!, from Kyle, David, AdamT, Kyle@otyp, and Ben. All together, we worked through the panini/linkage idea, browsed camera shops to find ball joints, and really set out to get the best design that's easy to build. That said, it can be impossible to find off the shelf parts to bring a new design to reality. More specifically, I'll say that my current source for searching (McMasterCarr) has lots of really *big* things, lots of door hinges or refrigerator hinges, but not so much in the *small* side of things. Is there...

Update: 9/25/2010 to http://openpcr.org/2010/07/treat-your-machine-shop-professionally/ Good comment from mo - spread the love around. I want to point out that the relationship with your machine/PCB/acrylic/wood shop can be challenging! It's important but not necessarily easy! If you can't meet in person it's tougher to build repertoire over email or telephone, no matter how charismatic you are. And though I'm usually close to my email, people in shops are on tools and machines most of the time. A phone call is a lot quicker and more personal, but conversations on the phone often lead to miscommunications...



Name that component!

Welcome to an exciting round of "name that component". Here's your host, Tito! Hi everybody, We are working to design our heated lid so that it can adjust to small differences in the size or height of tubes. In PCR, we're cycling the temperature of a small aluminum block between 50C and 100C. We place a plastic tube in each well of the aluminum block, which contains a liquid DNA sample. Now, if we simply have this setup, we will heat our samples to 100C and they will evaporate and condense in the lid of the tube. This is a problem, which is commonly solved by something called a "heated lid"....



Thermal pads

Just received the 2 test thermal pads in the mail from Digikey. BER165-ND is 3 mm thick and pliable. It runs about about $3.50 per OpenPCR (28 parts fit in a $94 sheet). 3M9601-ND is 2.5 mm thick and very soft, and about $1.20 per OpenPCR (25 parts fit on a $30 sheet) We'll want to test these out with our current heated lid to see that they work great and make it easy to maintain the temperature of samples. Once we receive the first set of aluminum and a new wooden case from Ponoko, we'll be able to test these out even better.
