Science Hobbyist


Nov 1999 to Dec 1999

Thank you for visiting SCIENCE HOBBYIST. We would love it if you would Add your comments to our comment book. Also see the Comment Book for K-6 Misconceptions Page.
2600 has learned that several small electronic hobbyist vendors were recently raided by federal agents brandishing semiautomatic weapons. News of these raids has been kept out of the media and many of those involved fear retribution if they openly discuss the case. Until now, these companies had operated for years selling harmless educational electronic kits (like wireless microphones) to students, hobbyists, ham radio operators, and hackers. Now their inventories are being seized at gunpoint--and their owners could be facing bankruptcy and prison time.

The U.S. Dept. of Justice is apparently re-interpreting federal wiretapping and smuggling laws to include small hobby radio transmitters. Even possessing so-called "Mr. Microphone" type toys can now put hobbyists at risk of looking down the barrel of a federal agent's loaded gun, a felony conviction, federal prison time, loss of property, and legal fees into the tens of thousands of dollars.

Ramsey Electronics and Super Circuits are just two of the companies recently raided at gunpoint. Both have good and longstanding reputations for selling inexpensive, quality educational kits and components to electronics hobbyists for many years through ads in electronic hobby magazines and their websites.

A high-ranking Justice Dept. official told one of the business owners the orders for these raids are politically motivated and originated from a very high level in the Clinton administration as a result of the Linda Tripp wiretapping case. "They just need convictions," the official said.

Earlier this year the Justice Dept. indicted Bill Cheek, the well-known and loved author of books on radio scanner modifications and Monitoring Times column writer. Bill was selling very simple "data-slicer" circuits (made from parts available at any Radio Shack) that could be used with a PC and a scanner to monitor radio data transmissions--including unencrypted police mobile data terminal (MDT) transmissions. Even after Bill had been diagnosed with terminal cancer, the Federal government refused to back off, even issuing a summons to court on the same day he was to begin chemotherapy.

In 1995 2600's BernieS was locked up in five different maximum-security prisons over 14 months by the Secret Service for possessing his laptop computer, his software, and ordinary electronic parts available at Radio Shack. He had been distributing parts, software, books, and pamphlets about cellular and coin telephones. The Justice Department's final investigation report stated "There were no victims in the offense."

This is a clear pattern of harassment and abuse of power by our Federal government against people teaching others about electronic communications. It appears our government doesn't want people to know this information. 2600 strongly feels this knowledge is important for people to have, and will continue spreading it at every opportunity. Write and call your legislators to complain about this injustice. You could be next!

Robert Beck, Phd,Physics, Developed a device from a patent that was obtained from a George Washington School of Medicine discovery. The device flows ><10 microamps current squarewave at 4 Hz, with a maximum voltage of 27 volts, this device will block receptors in the blood that stop pathegens(viruses, bacteria,parisites,etc.) from multipling, therefore they die. Also at the cellular level the body is electrical in nature. My question is: Has anyone looked into the resonant frequency of the body to d etermine if such a device would improve cellular communication and health with the possibility of increasing life span?

I was browsing around late one night when I saw this wonderful sight. Immediately i began rumaging through it for things I could do :) I found so many wonderful things. The first thing I made was the electrostatic motor with pop (yes, people in WA sa y pop, not soda) bottle, except I substituted the bottles with little film canisters and it works great. Well many more things I shall build with the guidance to your site (next in line, 400kv VDG). Thanks for the wonderful information and keep it up. A nyone who wants to trade or donate info with me, it would be greatly appreciated (ex. results of tests on various projects, etc) Wereserpent

Hi Bill I just read your Untried HPG Experiments page. At one point you say that rotating the magnets or the stator will produce a voltage----Not true. Just like Faraday said if you spin the magnets but not the stator nothing happens. Think of it like this...If you have two magnets attracted to each other do they care if they are spinning or stationary? What if one spins one direction and one the other direction? What is the field inbetween doing then? Nothing! I tried it. Thanks for the link to Thomas Valone's book..I went and bought it.

I have been into tesla coils for about 2 yrs now and am just about ready to start my second one. My first coil is 4.125 diam sec. with 14 turns of .25 copper tubing spaced .25 inches apart. my caps are of the saltwater beer bottle variety, 2 segment sparkgap and 1 12kv 60ma neon xformer. I am getting just over 30 inch sparks from this setup. Is this all I can expect out of this transformer?

I'm new to Weird Science, but not new to strange science phenomena. I was quite impressed with Bill's article on "Energy-sucking Radio Antennas". Since I've already built a small DC PM motor which continuously runs day and night fueled by emissions from a local AM radio station, I thought I'd try to augment the system by partially invoking the capacitive plate antenna scheme outlined in the above paper. I took two 2'X 4' sheet metal plates, one on the ground, the other atop a plastic trash can placed on the first piece....separation about 1 meter vertical. This big air-capacitor was placed in parallel with, an already, carefully tuned loop antenna. This loop antenna is configured to store power via germanium and zener diodes and yields about 8VDC on a capacitor...enough to occasionally flash a red LED when touched to the capacitor. Adding the capacitive antenna and re-tuning to best resonance allowed the metal plates to become part of the resonant circuit and added a healthy 5 to 6VDC to the capacitor. I now have a two-transistor circuit flashing the LED. I was very careful to test every hook-up scheme of the plates to insure that they were NOT simply adding to the length of the loop portion of the antenna. I believe that I have witnessed the action of a resonant capacitive plate antenna drawing static charge from the Earth's static field. I say this because I did not experience an increase in curent, just an increase in voltage.

I highly recommend that you all read Bill's paper on ' Energy-sucking antennas' as well as his paper "On the Possibility That Electromagnetic Radiation Lacks Quanta of Any Kind -or- photon dies screaming". Just thought I'd share.

There's something that's been bothering me for a long time radioactive materials (like uranium) give out alpha and beta rays (right?) and these are charged particles (right?) .so why do you need to have them undergo fusion and use the resultant heat to drive a turbine which runs a generator(thats what they do in a reactor (right?)) why dont they simply trap the particles on a conductor(like a solar cell and use it directly?

It is nice to know that there are other sci nuts out there, but is it not strange that when you start talking shop at a party you soon find yourself alone! I read where one of your q&a people said he was hit by a bolt abou 7 foot long working on or near a paper machine which indicated to me basically an unintentional vandegraph generator considering the rubber rollers etc. I found myself laughing. If he hooked up several bottles in a tub with salt water he could have generated enough to finish the job(death),and high order xrays as well!

I have to say that I LOVE your page! some of that "free energy" stuff is a bit left of centre, but the static and optic stuff is great. I had a thought about a way to make the one-lens telescope (http://amasci. com/amateur/teles.txt) easier to use. A cross hair or similar placed 20mm or so away from the eye (at the eye's nearest focal distance) provides a target to look at while you're getting the lens to focus. A piece of Perspex with a pair of crossed lines scribed on it should do the trick, or a small cardboard tube with two human hairs at right angles.

Help ! About 5 years ago I was working under a paper machine and had static electricity jump about 7 feet and hit me. About 2 weeks later I was hit again. Then I was informed by my fellow worker what had happened, so I decided to stay away from the source. Then about 3 weeks later I was walking (stooped over) near the same area and had a bolt jump about 10 feet hitting me in the head again. This time I knocked me out and drove me head first into the concrete, breaking my nose,spraining 2 fingers and splitting me forehead open. It knocked me out for approx. 5 minutes. Now I suffer constant migranes that no doctor can seem to cure. There was another fellow worker that was knocked out. And even one other that when hit had to wear a heart monitor for 6 months due to it caused her heart to missbeat. All in all over 20 workers had been hit before the problem was fixed. Does anyone have any thing in mind that might fix me ? Or even explain how it is all connected ? Thank You for your time

About your very simple electrostatic field sensor. I found a solution to charge build up on the gate and how to vary sensitivity. I published it in EPE magazine as "The Handy Thing" Look at "references" and follow the "EPE" on my web page and you will find a pic po it in action. The circuit is not shown but past copies of EPE mag can be got from EPE.

I am a sophomore at the University of Texas at Austin and I am currently engaged in building fairly large Van De Graaff Generator to power an ion pump at low pressure. For a capacitor, I am using an 18" diameter paper mache dome which I covered with a luminum tape. The support column is PVC pipe and sits into a plastic bucket. The top roller is made of aluminum and the bottom roller, Teflon mounted directly on the motor shaft. The belt is 1 inch thick and made of a material which stretches fairly ea sily and resembles the stuff you might see tied on a wooden stake at a construction site (not the yellow, plastic "CAUTION" tape). I put a strip of electrical tape around the outside of the belt to make it a little more durable. The brushes are formed f rom stainless steel wire mesh. I am using a 1/3 horsepower motor. I have a small commercial Van De Graaff which I use to feed positive charge onto the belt. I also have a neon sign transformer which I convert one terminal to positive DC through the use of diodes...this works somewhat but I think the small Van De Graaff feeds charge more efficiently. The problem is that I get a static field about 1 foot away but I cannot jump spark to the back of my hand longer than an inch. Once a spark does jump, th e VDG sphere may take 10 seconds to recharge. I heat everything thoroughly with a heat gun before I crank it up. I think I need wider rollers/belt for a capacitor of my size. I think my VDG is a little "out-of-proportion" being about 4 feet tall with a belt that is only 1 inch thick. Another concern is the amount of static charge that I can feel running down my PVC pipe. I would really appreciate any comments or suggestions! If you are in need of further information, please let me know.

suppose an anti-grav shield is invented. the air above it is protected from Earth's gravity, therefore it starts to spin off due simply to Coriolis forces?

I downloaded a sound wav from this site and it could not have been a more exact match to what I have been hearing. I originally thought it may be a train or traffic until I went on my anual fishing trip in B.C. far from any city and could still hear it just as intensly as I did at home. Mabye we all just drink too much coffee, but I don 't think so.

I would like to comment on the Super Collider , it must have occoured to someone that when you start powering up your going to change the magnetic structure of everything within a certain distance of it, living or not.This is not to mention the effect it would be in the event of a disaster. Anyone have any thoughts about the possibility of producing small super colliders for use with power cells ? I think the applications would be endless, and also be easily introduced , I have some thoughts as space t ravel being a big factor in the ability to push technology at leaps and bounds and could study this as a possible answer for reasonable reliable fuel .

All radio waves are broken into these two waveforms and standard radio waves (Hertzian waves) have an equal strength of space to current wave. But it is possible to change the strength or ratio of space to current wave to produce different effects. What I want to know is how do you change current wave to space wave strengths and what results should I expect when I do so. Please send three circuit diagrams showing 1/High space wave to low current waves, 2/Equal space wave to current waves, 3/Low space wave to current waves. Thanks WAZZA

First of all, i am greatly amused and enthused by this website, but i must say that the hand-drawn holograms are not true holograms in the sense that they utilize light interference--it is reflection (refraction) from the cruved surfaces of the compass-scratch. The interesting construction ensures that there are many different angles and directions at which these manipulations of light rays (not waves) can be viewed. Still a very interesting activity-- i'm not sure if you mentioned that the 3-d effect can be obtained by varying the distance between compass points gradually along the 'encoded' line. I look forward to many fun things from this site--

On Static Electricity vs Electromagnetism: It is useful to discuss static electricity separately from the rest of electromagnetism because charges, when they are motionless, create only electric fields, which act much like gravity (except they can both attract and repel and they are much stronger than gravitational forces). Once you allow charges to move, the forces they generate on each other become much more complex. This dynamic behavior has traditionally been called magnetism, but it is really only a variant in the behavior of electric charg es.

I was interested in your conversation about the molecular motion of energy dispersal in a wire. I thought that it was just an overall bumping of the atoms in a particular direction, and that the free electron was just how the direction was transfered. Thus, no electrons truly move, they just move the next atom creating a phase shift along the pure power axis(accounting for stored charges). Also, the more dense an element such as copper is may then be seen as more mass to move and thus lower conducti vity. This could then be related back to physical movement, just on a microscopic scale. Also, the wider a wire is increases the current and does not decrease it. Its just like a parrallel network, the more paths the higher the current and the lower the resistance. This lower resistance may also be due to the fact that the more atoms moving randomly, randomly produces more paths for energy transfer to occur. In turn, this may also explain why thinner wires heat up as some molecules cannot disperse the ir energy to the next molecule fast enough and thus build charge.(If you want me to discuss further, just e-mail me at{guru__69 at yahoocom <<

I have an idea that would be cool. My idea is to make candy bar that would stop people from getting hungry. People get hungry because the acids in their stomach have nothing to eat away at. The reason why the acids don't eat at the stomach is becaus e of saliva. If I could see what is in the saliva I could put that on the candy bar and then the acids would not be able to eat away at the candy bar so quickly. The acids would take at least a day to break the candy bar down. The candy bar would be fi lled with the necessary nutrients to supply the body the whole day. The acid would be eating the candy bar and taking out nutrients slowly. The process to eat away at the candy bar would take a day. If I ever make this candy bar it could be used as a w ay diet or for millitary use.

Your site is quite interesting, and would be even enhanced with the ability to print out photos & B&W text, but, I find the history of Tesla very typical of the "underdog" in all of us. It seems that great geniuses are always undermined unless they are very lucky, know the right people, or have a lot of money to begin with. The same is true of many talented artists, musicians, and inventors everywhere. On the other hand, who really knows what would have happened if Tesla was able to get the funding to complete his experiments. He may have split the world in two and then where would we be? I must admit, he was way ahead of his time. Perhaps in this age he would have had the right "environment" to be equally creative with the right financial support and technology behind him. The same could be said of Jules Verne, Michaelangelo, Da Vinci, Columbus, and many others. Such is the pricetag of genius.

I am searching for a bipolar ultra sensitive hall effect sensor.The uni-directional sensor did not work in our application when tested. The application is to simply sense the presence of a metal detector in a particular location and to act as a trigger. I do not have specs on the amount of electro-magnetism produced by the metal detector, but I expected to see a half wave type of square pulse when the sensor being uni-directional was used with what I assume is a bi-directional magnetic field generated by the detector. It seems to have roughly around the same minimal amount of operating magnetism as the specs of an ultra-sensitive bi-directional sensor spec'd from Allegro and I was wandering if anyone could offer any information and/or clarify whether uni-directional versus bi-directional would simply be the difference between a pulsed output and a digital level output when put in an alternating magnetic field or can I expect to see something more with the bi-directional sensor. It worked with a permanent magnet type of stimulus. Does anyone have a simple analog inductive coil sensing cicuit or any other which they could recommend. The operating level of magnetism described for the sensor was 35 gauss and I was wi\ondering if any one knows for a fact of a magnetically bi-directional sensor which will detect any less. Any info would be great.

Humans that are in motion and happen to carry an electric charge, relative to earth ground, can be detected using a simple electronic circuit. The electric field fluctuations to produce as they move around can be used for a motion alarm system. I have more details about this subject in my "Imagineering On-line Magazine" on my web site: www.DJandAssoccom I provide complete information on an "Electric Field Disturbance Monitor" in the magazine.

I believe that almost everything has its opposite. For instance electricity has: 'Negative and Positive', Megnetism has: 'North and South'. Megnetism and Electricty interact with each other. One side of a thing is used to control the other side. So the question is this: "what is the opposite of gravity?" Well, what is gravity? That can only be answered by WHAT GRAVITY DOES... What does it do? It Pules.... What is the the opposite of pulling? PUSHING (of course)... What in the physical universe PUSHES? The Answer: LIGHT!!! Light pushes against things, maintaining the ballance between Objects in Space that would otherwise slam into eachother because of gravity. There are to phenomina in the Universe that demonstrate this. (1) Black Holes: Here the Pulling force of gravity is greater than the Pushing force of Light. Thus pure gravity is Pure Darkness which is 'HELL'. (2) Super Novas: Here the Pushing Power of Light overcomes the pulling force of gravity and the star explodes because pure light pushes. Pure Light lifts you UPWARD towards 'Heaven', But Pure Darkness Pulls you down to 'HELL'. When a person dies, if there is darkness within them it PULLS then downward to hell. When a person dies, if there is Pure Light within them it Pushes them away from the darkness into the LIGHT. John 3:16-21 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. 21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God. Also, Luke 24:51 Jesus (The LIGHT of The World) Flew up into Heaven without any special device. How? The Light within Him, pushed Him away from the earth. All of those that believe in Him (Jesus), one day will be lifted from the earth and fly to heaven. How? If the Light of Jesus' Presence (the Holy Spirit) dwells within you, you will be taken up into heaven, the event know as the 'Rapture'. But if you hide from the Light, and darkness is within you, that darkness will PULL you down into Hell. The only requirement is to believe that Jesus died on the Cross, was buried, and Rose Again from the dead. If you believe, and trust in Jesus he will save you from the GRAVE(ity) and Pure Darkness of Hell, and you also will be lifted up from the earth one day. P.S. The objects called U.F.O.'s are really Angelic beings. According to Ezekial Chapter one (1:15,16) the 'Flying Saucers' are the used by the Angelic beings, not flesh and blood biological beings. These ships use light as there means of resisting gravit y. Almost all of the sightings are of Bright Flying Spheres. The increase in "UFO" sightings since the 1950's is a signal that Christ's Return is near. You see there is a war between Light and Darkness and that war is becoming Visible as the Angels and Demons Fight in the Airways all over the face of the earth. The Demons know that Jesus is coming, and that is why there is so much activity. The Demons are trying to stop Christ from returning. The final resistance is called the Battle of Armageddon (Revelation 16:16). If you want to build an 'Anti-Gravity' device I recommend that you look for the answer in the Light Spectrum.

I just saw a special on Discovery channel about the Taos hum. I knew I wasn't alone in hearing this sound that I first heard about 2 years ago in Beloit Wi. I hear it as a low pitched hum that penetrates anything and is heard at all hours-some days str onger than others. I became aware of it when I would hear it at night thru my pillow when I was trying to fall asleep. I was curious why I would hear it at all hours in the middle of the night as I associated the sound with a large generator of some sort. There were alot of factories in the area and I thought the sound would go away on Sundays and certain hours, but it didn't. I would hear it day and night and especially stronger at night,just as strong inside the house as outside. I thought moving would make it go away. I moved about 2 miles away and still heard the hum. I see on your website a comment from someone in Rockford IL hearing the same thing-Rockford is only about 20 miles south of Beloit. This has to be something confidential that the governm ent knows about and probably because of some health risk or military secret will never tell the public about. It gives me peace of mind to know I am not alone.

In re the reason airfoils really work, Beatty's articles are great! However, there is one mistyake. As to horizontal stabilizers, at th e tail section, these are not necessarily of a symmetrical cross-section--as they must exert a downward force during flight. Thiose without sa symmetrical cross section have a negative angle of incidence; those with a (near) symmetrical cross section actually have an "upside down" leading edge camber (similar to a regular wing cross section) with a near zero angle of incidence. This design is illustrated by the fact that if the "tailplane" )horizontal stabilizer) is allowed to "ice-up" (e.g.,during Winter) the reverse "lift" or downward force normally present, is lost.The plane may abruptly pitch into a streep dive. The FAA recognizes that tail icing is a real problem,and may cause drastic consequences.

First of all, I don't want to lend the impression that I am a know-it-all. I also have a degree in electrical engineering, and the information I received was somewhat different than that which was presented in reference to "which way does electricity flow?". That is NOT to say that my information was correct...only different. I was taught that electrons flowed from negative to positive, and that there were valence band "holes" left by these flowing electrons which represented the lack of a negatively charged particle. This creates an imbalance in the overall charge of the atom. This phenomenon is not synonymous with a flow of protons. It is, however, the lack of a negative charge, which lends credibility to the theory of positively charged ions flowing in the circuit. This vacant valence band "hole" then enables an electron from an adjacent atom to change it's orbit to the "positively" charged. Of course, this is happening on a mind-boggling scale, but the "theory" is evident. It has been my experience that there are still two schools of thought. Those who believe that current flows from positive to negative, and those who believe that current flows from negative to positive. It all depends on your definition of current. If electron flow is current, then it flows from negative to positive. If "hole" flow is current, then it flows from positive to negative. I conclude by stating that you obviously have invested more time and study in this area than I, and at this level, it really is "theory" after all, isn't it?. Thanks for the site. It's very stimulating.:-)

Last year in 9th grade my science fair projet was that I tried to determine how acidic rain water effected plant growth. I did this by having my dad put a bowl of water on his office roof in the city to collect rainwater. Then I built a green house. The results were quite good, and out of a 160 point project I got 160 points -puck51

Good day from Russia! My name GEORGE KHOBOTJEV. I have 37 years old. I have too wife Helen, daughter Kate 11 years ols and mom. We live in Moscow, capital of Russia. I shall be glad if in result of our correspondence you will learn a lot of new about culture of Russia, about a her history and about modern events. Unfortunately, now Russia experiences very difficult times, and with meal in our country it is now very bad. After falls of rouble in 3-4 times many products have disappeared from shops and to buy food now much more difficultly than earlier. Therefore I shall be grateful for your any help. That will help us to go through difficult winter, and not only us, but also our new second child, which birth in December. Each day we shall struggle for life. Thank you! My e-mail: hobot at ropnet.ru

The article about traffic jams makes sense, although I doubt that a single vehicle would have a very far reaching effect. I think the basic problem is that a given lane can carry only so many cars per minute, and I worked out years ago that this asymptoted to around 40 cars per minute, given the need to space vehicles to relate to reaction times and braking distances. However, the number of cars per minute can be pretty constant whether its bumper to bumper at a crawl, or spaced out at high speed, so that the flow is basicly unstable and easily disturbed. The fundamental solution is social - that people adopt a culture of driving far apart - the further apart the faster... but its not so obvious. But once the intrinsic capacity of the road is reached, you are stuck!!!

A really neat idea for an advanced science fair project is presented in the Dec. issue of ANALOG SCIENCE FICTION and FACT ( pg. 40 ). It is called The Worlds Simplest Fusion Reactor.I suspect it could lead to a real breakthrough in the search for economical energy that was pollution free.

Studies have shown that sites get wider readership when offensive language is culled. .lindsaybkscom has several texts available for investigative science questions. Another game to play in traffic jams is to allow five to seven car spaces to form in front of you in your lane and see how many impatient drivers will change lanes to fill the vacuum! Once on a midnyt flyt from ANC to SEA I noticed static discharges flashing from the nose to wingtip, delineating the 'bow wave' of the craft. Fascinating display, the sparks ranged from barely visible to an estimated 12 inches wide, and at least twenty feet long.
