    12K rpm of ideally constant RPM…. That is darn fast for most industrial systems (most normal bearings are rated to 6Krpm max), so you’re not going to get too far away from aerospace parts until you slow that thing down, probably 3:1 minimum.

    A list of ideas from my fuzzy memory:

    -Induction power supply (Motor-generator setup, although since you have 200 rps, you’ll need a really high pole count generator to make this work as 10KW would normally be at least 10KHz, which was the upper end of the frequency spectrum for MG sets anyway) -Skid mounted waterjet pump (good luck finding a pump that would keep up, most are designed for much lower RPM) -Centrifuge (fun for pressure squeezing composites, or purifying uranium… er… strike that) -Giant POV display of death (oops, my flywheel just disintegrated)

    Just remember, belts do not like spinning anywhere near this speed, so any belt drive will either disintegrate or try and do an impersonation of a perfect circle then disintegrate at the current output shaft speed (remember your maximum FPM). Also, I really don’t think your average snow mobile drive train could handle this speed. And it’s only 15hp from your other conversations.

    We have to figure out a better way to visualise 4D infometrics.

    I had researched on this several years ago. Back then, IIRC, Kopin sold their QVGA binocular microdisplay module in single quantities of $230 (it used to be on their website actually). Also remember, that Wowee had in their $100 RC camera car (I have one of the original ones on clearance for $40 years ago) a cheap RC car, IR sensitive camera, and analog video transmitter, going to a black and white QVGA monocle headband with a 1/8" plug providing power and standard composite video feed to the screen. Bulky, but the optics tend to cost as much as the display, if not more, at smaller sizes.

    In fact, the Wayback machine resurrects their posted 2009 prices for their electronic viewfinders.

    CyberEVF 230K $125 (QVGA monocle) BDM-230K $200 (QVGA dual display) BDM-922K $400 (VGA dual display)

    And here we have the local branch of the Taylor Swift fan club. Looks like they got turned down for a cameo again.

    Nate’s not riding in on a V8 snowblower today?


    In other news, those RN-XV’s look good. I don’t know if a breakout is actually a good idea as your cost difference between those and the raw module is only $5.

    From the chips and the writeup a TI Sitara running a Cortex A8 CPU (not sure of the clock speed, but capable of 300Mhz up to 1GHz), 32MB RAM, 256MB NAND, Zigbee, and Wifi. The Sitara doesn’t have a PowerVR GPU, so no 3D gaming, but I’ve seen low end smartphones with less horsepower.

    Hi, I’m smokey, the magic smoke from inside your ICs. Today, we’re going to demonstrate what a short circuit in a microwave can do to all the electronics in your house.

No public wish lists :(
