  • Lions vs Bears 09/12/2010-Horrible call/rule is deleting most posts about the fans making a statement, well, If you like football, you need to speak up and voice your opinion. New NFL rule is going to ruin the game of football: It is clear that this rule needs to be changed or refined in some manner. What I don't understand is that if someone is running a ball in the end zone and just the tip of the ball breaks the plane, it's a touchdown. Who cares if the defense plows him back 3 yards after that "Micro-Second"? However, when a receiver "Catches" a ball, "Lands" both feet, makes "Contact" to the ground with his knee and butt, and finally, the ball "Contacts" the ground for a "Micro-Second"before the ball is "released" or "dislodged" from the player's hand, that has to be reviewed to see if he's a skilled enough player to complete the "Process" What a joke!!

  • TPB #44 -High Speed LED Flashes This week's video is about very high speed flashes and whether LED based flashes are practical at these speeds. The dominant flash in this space is the air-gap flash with it's half microsecond flash duration it is about 100 times faster than a typical speedlite flash from Canon or Nikon. I do some calculations that try to figure out how many LEDs you would need, what kind of current you'd need to driver those LEDs, and the efficiency of an LED flash compared to an air-gap flash.

  • Earthshift is already taking place Due to the various high earthquake in various parths of the worlds, the earth is slowly shifting and its axis is tilting and our days are getting shorter. Stright From Yahoo News: WASHINGTON (AFP) - The powerful earthquake that shook Chile on Saturday probably shifted the Earth's axis and made days slightly shorter, a NASA scientist said. Richard Gross, a research scientist at NASA's Jet Propulsion Laboratory in California, calculated that the planet's axis would have shifted by eight centimeters (three inches) during the 8.8 magnitude quake, NASA said in a statement. Earth days are 24 hours long because that's the amount of time it takes the planet to make one full rotation on its axis, so shifting the axis would affect rotation. If, indeed, the planet's axis did shift by eight centimeters during the Chilean quake, days would have shortened by 1.26 microseconds, Gross calculated. A microsecond is one-millionth of a second, so no need to adjust watches just yet. The Chilean quake shifted the Earth's axis by even more than the 9.1-magnitude temblor off Indonesia that set off the deadly tsunami in Asia in 2004, Gross worked out. That's partly because the faultline responsible for the earthquake in Chile "dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake" and is more effective at moving Earth's mass vertically and shifting the planet's axis. The 2004 quake in Asia caused the Earth to move by around seven centimeters ...

  • Recorded electronic frequency oscillations I am able to hear the following transmissions 24 hours a day. As I layed down for the evening in a quiet room, I decided to place my recorder right next to me on my pillow and see if it was sensitive enough to capture some of this phenomenon. My recording is what it was able to pick up. Note -you will need to turn up the volume to hear it well. Of interest: The microwave auditory phenomenon, or the microwave hearing effect, pertains to the hearing of short pulses of modulated microwave radiation at high peak power by humans and laboratory animals. Anecdotal and journalistic reports of the hearing of microwave pulses persisted throughout the 1940s; and 1950s. The first scientific report of the phenomenon appeared in 1961. The effect has been observed for RF exposures across a wide range of frequencies (450-3000 MHz). It can arise, for example, at an incident energy-density threshold of 400 mJ/m2 for a single 10-microsecond-wide pulse of 2450 MHz microwave energy, incident on the head of a human subject. And it has been shown to occur at an SAR threshold of 1.6 kW/kg for a single 10-microsecond-wide pulse of 2450 MHz microwave energy, impinging on the head. A single microwave pulse can be perceived as an acoustic click or knocking sound, and a train of microwave pulses to the head can be sensed as an audible tune, with a pitch corresponding to the pulse-repetition rate (a buzz or chirp).

  • dye laser at CERN.mpg In 1976, CERN ask me to develop a pulsed laser for illumination of bubble chambers used to photograph the traces produced by the ionizing particles. to meet these conditions, the laser must have a maximum spectral width to avoid the speckle effect. A speckle pattern is a random intensity pattern produced by the mutual interference of a set of wavefronts. To reduce the speckel effecte the laser muss have the follows caracteristics : Broad spectral width No polarised output Superradiant emission Vibration of the laser medium All this 4 conditions will be satisfied with a microsecond wall ablation flashlamp pumped Dye laser. The Rhodamine 590 dye has a spectral bandwidth of 80 nm the superradiant amplification was achieved by using a long and small diameter quartz tube containing the laser dye in methanol. No resonator was used only a rear mirror and a flat antireflexion output coupler . The vibration of the laser medium is favorized by the very high shock waves during the ablation Of the flash wall in 1 microsecond. The laser emission is 500 nanoseconds and 300 mJ ( 600kW)

  • Laser camera trigger for high speed shadowgraph - ~10 microsecond light pulse This video consists of a description of a laser based camera trigger mechanism for use with a high speed shadowgraph. A spinning mirror with a slot in it is used to create a short pulse of light. Part of the mirror is covered with a black disk. When the laser reflects off of the mirror the resistance of a photocell is reduced which allows a relay to activate which triggers the camera. When the laser impinges on the black disk the resistance of the circuit is increased to much for the relay to activate.

  • Arduino ignition timing controller Very simple ignition controller. Basically just counts the time since the last ignition reference signal (represented here by the hall-effect sensor output of a computer fan), calculates degrees per microsecond and rpm, then calculates microseconds to next ignition event (represented by the timing flashlight) by looking up degrees per rpm in an array that's interpolated for smoothness. Here the advance is between 0 and 36 degrees. If this were on an actual engine, you'd also want an array for vacuum or load or whatever. This could run a real engine, but it was just for fun and it never will. I will post a link to the code if anyone wants it.

  • Teach Astronomy - The Origin of Matter Where did the matter in the universe come from? A bare microsecond after the big bang itself, the universe consisted of a sea of ultra-high energy gamma rays and particle-antiparticle pairs, in particular quarks and antiquarks, electrons and positrons, and neutrinos ad anti-neutrinos. The particle-antiparticle pairs were being created spontaneously from pure energy and disappearing, all on very tiny timescales, but there was a slight asymmetry in the ratio of matter to antimatter or a slight excess. Typically, for every hundred million antiquarks there were a hundred million plus one quarks, similarly for the electrons and positrons. This meant that as the universe cooled and radiation was no longer able to create quarks and antiquarks spontaneously, when the quarks and antiquarks annihilated to form gamma rays for the last time, there was a slight excess of quarks left over, one part in ten to the eight. In this way, the universe, when it recombined and matter and antimatter annihilated, was left with a huge amount of photons and a tiny amount of particles and no antiparticles at all.
  • RFID test at Ohmspace Excluding the coils, this RFID design uses only 6 passive components (5 capacitors and 1 resistor). The current implementation can read the RFID tag at 4 inches away. The trick here, implements a one shot 8-Bit Sigma-Delta ADC that can acquire a sample in.3.2 micro seconds. The period of a 125kHz pulse (used by the RFID) is 8 micro seconds wide. If we are just looking at the "time ON" of the 125kHz we have a 4 micro second window. Perfect for the 3.2 microseconds required for the ADC. Now what makes this trick is that now we have the ability to sample every 125kHz pulse to look for the modulation or change in ***og output of the pulse. Since we are also step-locked with the 125kHz generator, there is no filtering. Filtering can degrade the signal an turn your modulation into a series of triangle waves which is fun in and of itself to demodulate. By eliminating any filtering requirements, the power is kept low, while the sensing distance is maximized. The video is just what I have to date in terms of reading the raw RFID signal.... later I will be decoding the bit pattern into meaningful RFID tag data.

  • Arduino-based RC motor ESC -- 2000 rpm cutoff? **Update: I have since hooked up 3 dual MOSFET drivers (TC427) to the gates of the driving mosfets and am going to hook up more fets in parallel to the ones installed to reduce resistance and increase current. ** This is an attempt to create an ESC using an Arduino and six Power Transistors. The setup: Arduino Mega E-flite 2S 7.4V 800mAh li-po battery Neodym 300 1200kv 96W BLDC motor 8x6 prop 4x: RFP50N06 Power N-Channel MOSFET 1x: TIP35N Power NPN Transistor 1x: TIP122 Power Darlington NPN Transistor The program starts with a 30ms delay between each clock pulse that decrements by one every six pulses. When the red LED attached to pin 12 lights, it switches from a 5-millisecond "delay" to a 5000 microsecond "delayMicroseconds". From there it decrements by units of 10 microseconds until approx. 2000 rpm where it randomly stops and screeches. I don't really know how fast it gets to before stopping but I would presume it would be around there (2000rpm); nowhere close to the ~10360 rpm the motor is capable of. I've had a lurking suspiscion that it is due to the insufficient amount of voltage provided to the gates of the FETs by the Arduino (since the default logic level is 5V) and because it is activated on a 1/3 duty cycle, the ***og voltage getting to the gate is really 5/3V (please correct me if I'm wrong; I'm a newbie at this stuff :P) and a quick peek at the RFP50N06 datasheet reveals that at that Gate-Source voltage it won't conduct much current at all.

  • A single source femtosecond-millisecond broadband spectrometer A single source femtosecond-millisecond broadband spectrometer EC Carroll, MP Hill, D. Madsen, KR Malley, and DS Larsena Department of Chemistry, University of California, Davis, One Shields Avenue, Davis, California 95616, USA Time-resolved measurement of population dynamics extending over femtosecond to millisecond time scales typically requires a combination of transient absorption techniques involving different laser systems and detection schemes. The spectrometer design presented here facilitates transient absorption measurements over 12 decades with a single ultrafast laser system by picking pump and probe pulses independently from the laser oscillator pulse train. Unamplified pulses seed a photonic crystal fiber to a supercontinuum probe source for spectrally resolved measurements. The utility of the system is demonstrated by measuring triplet state dynamics following photoexcitation of vitamin B6 in aqueous solution. Time-resolved transient absorption TA, or optical pump-probe, spectroscopy has become an indispensable technique for characterizing photoinduced population dynamics in biological, chemical, and solid-state chromophores. Dynamics in such samples often occur over multiple time scales ranging from femtoseconds eg photoisomerization to milliseconds eg protein conformational changes. In a TA experiment, a pulsed light source excites a subpopulation of the sample into an electronic excited state and its relaxation dynamics is subsequently probed by ...

  • KRONOS- Portable Microsecond Flash Photolysis Spectrometer Kronos is a portable flash photolysis spectrometer designed for transient absorption and emission measurements on the microsecond and longer time scale. Kronos can measure solid and liquid samples in the transmission as well as the reflection mode. The Kronos patent pending design utilizes a Xe arc flash lamp as an excitation source, which allows for wavelength tunability. The photoinduced transient species are investigated by passing the output of a white light emitting diode (LED) through the sample. Using an LED as a probe light source results in superior stability and low noise. The probe wavelength range of Kronos is 425-700 nm. After traveling through the sample, the probe light passes through an interference filter. After that a 10 nm wide section of the spectrum is delivered to the detector photodiode. The detector voltage output is digitized and transferred to a PC for generation of a kinetic trace and for further manipulations.
