Current Hardware Stuff

Tube shims:

Tube shims for centerfuge are finished. They will be uploaded to shapeways if anyone wants to get 'em.
Should be cheap. Will modify to cheapen.

PCR:

Current PCR block. Quotes for it's manufacture are woefully high. Looking to decrease this cost. Prices:

• $950 (!!!) to have it 3D printed.
• ~$300 to $400 for a custom machining job.
•  ??? Other methods of manufacture (sand casting, investment casting, ect...)?

Ways to possibly lower the cost:

• A Heat conductive polymer
• Some kind of putty (?? No idea what this was ??)
• Ceramic block
• Decrease size of block
• Remove hard to machine features
• Remove block entirely and construct PCR from heated baths
• A mixture of a few of these (simpler block with baths rather then tube shaped holes)

Heating Rate: .7 to 1.1 C/S
Cooling Rate: 2.0 C/S

PCR Design:



Cheap PCR (maybe?)

Software/Interfacing stuff

For the PCR interface software we need:

• A menu bar with save, load, PCR settings, about, comm settings, connect, and disconnect
• A list box that allows us to add time/level points.
• A set of textboxes that we input new times/levels in (with a button)
• A picture box depicting the heating profile we are setting
• A set of textboxes/labels that indicate the current state of the PCR.
• A set of buttons, execute the current sequence, reset the sequence, and stop/pause the sequence.
