Winners

The motors made for RC planes and cars are high speed and high power.

For example, the Turnigy Trackstar 1/10 12.0T 3300KV Brushless Motor, $23 specs are:
Kv: 3300
Max Voltage: 15v
Max current: 35amps
Watts: 550
Resistance: 0.0221Ohms
Max RPM: 50000

The load on a microfuge will be greater–22 tubes x 1.5 ml can be roughly 44g, figure a 100g total load with the rotor. So slower than max, but still quite fast.

High power ESC modules are sold to run these motors. So they take DC power, and a servo like signal (PWM), +5, GRD.

So a 10k RPM microfuge can be made with one of these motors + ESC, a servo for locking the lid, and a microcontroller to run it, take speed / time settings, and monitor and show the RPMs on a display.

Power could be from a PC power supply or a dedicated supply.

In the last decade or so, dinosaurs have started being depicted as brightly colored. The reason for the trend of brightly colored dinosaurs in movies is that in recent years techniques for identifying pigments from fossils have been developed, using electron microscopy and ion bombardment mass spectrometry.

News report: Ancient Pigments Unearthed: Fossilized skin reveals the colors of three extinct marine reptiles by Ed Yong. The Scientist, January 8, 2014
Original article: (Abstract) Skin pigmentation provides evidence of convergent melanism in extinct marine reptiles. Lindgren et. al., Nature 08 Jan 2014

and news report: Pictures: Dinosaur True Colors Revealed by Feather Find, Chris Sloan, National Geographic Daily News
Original article: Zhang et. al., 2010

Fossil color studies were pioneered by Jakob Vinther at Yale

No doubt movie speculation is running far ahead of the science, but these are the discoveries that unleashed the trend of brightly colored dinosaurs. At this point, it is reasonable to think dinosaurs are as brightly colored as birds or reptiles are today, and in some cases the coloring of specific species is known.

Further notes on using digital camera sensors as high density multimodal sensor arrays.

1) Detect loading / strain using a module incorporating a strain sensor (e.g. the resistive type used in scales and strain gauges) to a diode. The diode is coupled to a fiber optic line that takes the signal to the camera.spectrometer.

2) Position sensors. Use an arc of partially clear plastic that has a light at one of the ends at the arc edge. A fiber optic line at the oriented normal to the arc gathers light that takes the signal to the camera. As the joint moves, the plastic arc moves and distance between the light and the fiber optic changes. This change is converted to a position.

For joints with 360 rotation, the arc of plastic is replaced by a disk. The light source is placed at the center, and an opaque radial line gives each position of the disk a different light intensity.

3) Touch sensors. Use my previous idea of an array of sensors embedded in a squishy and translucent layer with one or more light sources. Touch distorts the light path of direct or reflected light between the light source(s) and sensor in reproducible ways. The set of sensors is trained to recognize the pattern of light formed by different touches. The pattern may also be changed by movement of the surface, for example if the array of sensors covers a hand, and could bed used to detect hand position.

4) An array of fibers can be placed to collect light from a spectrometer. An array of spectrometers can be developed using this approach, as the camera can collect light from several 1D fiber optic arrays.

Does there exist a project to assemble an online library of ancient written works intended to be complete? It sounds ridiculous, I know. But, if you start back far enough–say 3000 BCE–there is hardly anything to compile. And then the project can work forward until the project spreads out too much.

There are practical problems–images vs symbols and alphabets, fragmentary or derivative manuscripts, arguments over translation, historical translations versus modern ones, organization by region or language, but they have all been worked over by traditional publishers. The result would look like a cross proto-Project Gutenberg / Wiki.

If anyone tries this (assuming I just haven’t heard of it), I fear one of the most frustrating issues would be copyright. Museums forbidding the taking or use of images of the rare manuscripts or tablets or whatnot that they control.

It seems that most of the ancient manuscripts are described are referenced in fragments in medieval studies books and rare manuscripts. I hear about this stuff by third hand descriptions rather than by to links to online reference copies.
