  • Frontiers/Controversies in Astrophysics (ASTR 160)

    Exoplanets are introduced and students learn how astronomers detect their presence as well as the challenges associated with it. Physics equations are explained as well as their importance in the context of the course. A number of problems are worked out to get students used to dealing with large numbers in calculating planetary masses, interplanetary distances, etc.

    00:00 – Chapter 1. Course Logistics
    06:15 – Chapter 2. Exoplanets
    12:56 – Chapter 3. Physical Units and Significant Digits
    33:23 – Chapter 4. Calculating the Distance between Planets and Stars

    Complete course materials are available at the Open Yale Courses website: http://open.yale.edu/courses

    This course was recorded in Spring 2007.



    SUNKEE DC 3V to 7KV 7000V Boost Step-up Power Module High-voltage Generator

    3.4V DC in 7000V DC out! Way easier than a flyback transformer!

    I have a huge, heavy neon sign transformer (NST) that puts out 5000 volts (5kV) at 18 milliamps (0.018A) and this little box puts out a much scarier spark, although the this doesn’t seem to travel through stiff wires so I couldn’t make a mini Jacob’s Ladder out of it (yet). I’m thinking that means it has very low amps…I haven’t measured it yet (use a high voltage divider probe or else you’ll wreck your multimeter).

    One side has 2 white (or red) wires: those are your outputs. Mine has 2 white outputs.

    The input side will have two DIFFERENT color wires (1 red and 1 white). You have to hook positive input to the red. Hook negative input to the white.

    In my photo the tips of the output wires are exactly 1/4″ apart. The input voltage was 3.3 volts DC. The spark was loud, blue and awesome! Very crackly like a stun gun in the movies. I built a demo fusor (and made the Plasma Club) yet this seems scarier!

    You must input DC voltage. You probably shouldn’t go over too high or so, although I did momentarily and got a huge spark. The specs say 3 volts. I needed 3.4 to get a steady spark. I’ll update if I blow it up and I’ll include the final voltage.

    If you have the wires farther than 1/4″ then either it won’t spark or you’ll crank up the voltage really high to get a spark: either way you might destroy this device.

    If you apply voltage and don’t provide an escape for it (a spark or powering something) you can destroy this unit. That’s another danger of trying to make a bigger spark gap: you’ll be powering this unit but if there’s no spark you can destroy this unit apparently. I think that’s what the advert means by “don’t let the pressure build up” meaning to keep it under load.

    For about the price of a single firework you can play with this. I haven’t destroyed mine yet. It fills the room with ozone quickly (toy train / slot car smell).

    Get a sturdy holder apparatus for the output wires so you don’t die.

    It came in a cute box, but no instructions other than to keep it away from static. I have a feeling that if you rubbed this on a static wool sweater you might kill yourself with it.

    Not bad for $7 on Amazon! Still working a month later!

    Here’s my blog post about it: http://michaellogusz.blogspot.com/2016/07/sunkee-dc-3v-to-7kv-7000v-boost-step-up.html
