  1. My main problem is damage to cars. Dents, scratches, burst tyres, broken head lights and somebody even rammed something through the radiator once. I put cameras up but the tapes only last 8 hrs and I don't want to put lights up because I live opposite the main road and I think a sudden bright light may cause an accident. The biggest problem is its the companys car as well as my wifes. I tried a pir triggered camera but the range is too low and the angle of the lense is only about 50 degrees.
  2. Get some anti vandal paint thin it a bit and set up a spray booby trap. If you can get different colours (I've only heard of red) you will get a unique signature coloured crim walking around looking like a total plant and being very noticed. The stuff a friend uses at the school he works at does not come off for weeks and if you thin it enough it should soak through clothes onto the skin. Take that you multi coloured freaks By the way have you seen the wireless alarms available now. I don't Know how far your shed is but I have one and it has an auto dialer built in. It calls 5 numbers in sequence if no one answers the last call and plays a recorded mesage. Its remote controled you can have magnetic or pir sensors, it has spare relays to power other devices and a solar powered external siren. You can also set each zone to cause a chime from the control unit when something triggers it with the alarm disarmed and you can set up 3 different arm options only arming selected zones even when using the remote to set it. I know its not in the spirit of what your doing but it might help. Its also has an answer machine/memo recorder and phone in remote control and if it goes and rings you you can dial back in and listen through the built in mic. Batterys in pirs last about 6 month in my house and the reed switch batterys last about 1 year.
  3. A man walks into a bar, and orders a beer. He drinks the beer, then stands on the bar, drops his pants and pisses all over the place. The barman freaks out. "You dirty disgusting pig! How dare you come into my bar and urinate! I'll beat the shit out of you..." The man begins crying. "I'm sorry! Its ruining my life. I can't sleep. I do it every time I have a drink! It's worrying me to death, please don't hit me..." The barman takes pity. "Look, I have a brother who is a psychiatrist, here's his card, why don't you see him?" The man hugs the barman, shakes his hand and leaves with a thousand thank yous... Six months later, the man walks into the bar, and orders a drink. The bartender says, "Okay, here you go... Wait! Weren't you that guy who.." "Yes", the man replies, "and I went and saw your brother. He is fantastic, I am completely cured." "Well, that's great. This beer is on the house." So the man drinks the beer, stands on the bar, drops his trousers and pisses on the bar. "You bastard! I thought you said you were cured!" "I am! It doesn't bother me anymore...", says the man.
  4. After having their 11th child, a very thick couple decided that that was enough and they could not afford a larger house. So, the husband went to his doctor, and told him that he and his wife didn't want to have any more children. The doctor told him that there was a procedure called a vasectomy that could fix the problem. The doctor instructed him to go home, get a banger, light it, put it in a beer can, then hold the can up to his ear and count to 10. The man said to the doctor, "I may not be the smartest man, but I don't see how putting a firecracker in a beer can next to my ear is going to help me." So, the couple drove to another doctor to get a second opinion. The second doctor was just about to tell them about the medical procedure for a vasectomy when he realized how truly backwards these people were. This doctor instead told the man to go home and get a banger, light it, place it in a beer can, hold it to his ear and count to 10. Figuring that both learned physicians couldn't be wrong, the man went home, lit a banger and put it in a beer can. He held the can up to his ear and began to count. "1, 2, 3, 4, 5 . . . . ", at which point he paused, placed the beer can between his legs and resumed counting on his other hand
  5. Sex is so dangerous these days. If you sleep with someone you get s.t.d. if you sleep alone you get r.s.i.
  6. A man walks into a pet shop and says to the owner. "Ok I want to buy a pet, but I don't want a boring normal pet, no cats, or dogs or budgies I want something different." The pet shop owner informs him that he has a talking centipede. "really?" Says the man "How much?" The owner informs him that the talking centipede is £50. Happy with the unusual offering the man pays the money and takes his new pet home. On getting home he lays the match box with the centipede in it on the table, opens it and says "Hello mr centipede, fancy going to the pub for a few drinks?" The centipede says nothing. Figuring it must be tired from the journey he decides to leave it for an hour and try again later. An hour later he opens the match box and says "Hello mr centipede, fancy going to the pub for a few drinks?" The centipede again says nothing. Starting to get suspicious the man decides he will give it one more hour, and if the centipede doesn't talk he will take it back to the shop for a refund. An hour later the man opens the match box and says "Hello mr centipede, fancy going to the pub for a few drinks?" The centipede says "I heard you the first time you moron! I'm putting my shoes on
  7. Sorry I find it hard to keep track of where I post. I replied to your pm but my connection cut as I sent so just in case yes enjoy. I can't afford to get involved so its no use to me. Please tell us how you get on. Might be best to use the centrifuge clutch mech from a petrol mower to drive it. This way you avoid motor and power supply stress if someting stops it turning.

    X-Rays

    If you want lead glass like you see in a xray room your looking down the barrel of a grand. If you plan on buying an old xray machine don't, they are usualy from tight dentists who run then into the ground and only buy new when they get caught with dangerous equipment. My company was asked to service equipment for a dentist that was untested and so old it was ilegal. Don't bother you'll hurt your self or someone else. The higher the kv the more penitrating the radiation. You will not know this with an untested old machine. I don't want to spoil your fun but
  9. It seems as if their work would be pointless. They will be guted. Narf point.
  10. Ithink the only way to change the past is to know the future.
  11. Pasive infrared sensors have an infrared sensing component. The lense on the front focuses the ambient heat from segments of the surounding area like the blades of a chinese fan onto the sensor. At start up a timer allows the value of ambient heat to be set then switches the circuit to comparator mode. The preset value is allowed to vary slowly but abrupt changes vary faster than the preset can and a relay switches on. The lense gives a pulse effect as a heat source passes each segment and this can be used to prevent false triggers by counting the number of pulses in a given time. A pir that gives you the option of selecting the number of pulses before triggering will be best as you could set it to five and place it at right angles to the door. Only someone passing five segments in a row will trigger the pir but at close range that will only be a step. If you can put it in this position you will only need a narrow angle. The wider angle one may be more expensive. Also bear in mind that some use solid state relays and require a minimum wattage load like the 500 watt bulb they normaly operate. If you plan on wiring something else to it other than the bulb you may need to put another load in parallel to get up to the required power. If the load you are using is higher you will have to set up a seperate relay in parallel to operate the load. Trying to sheild your heat will probably make the area your in lower than ambient and still trigger the sensor. The only way round a decent pir is to move so slow that the change doesn't register as it is within normal allowed ambient temp rise rate. This is so slow it wouldn't be worth the effort.
  12. That cip thing looks a bit like something I was going to have a go at building but I didn't realy look to see if there was a design on there. I was thinking of a circular track with a weight on it. The weight goes round the track and the track rotates once per revolution of the weight. It would shake a lot and there is a lot of lost energy but some net thrust. It would provide more thrust than ion prop and could be driven by electric motors. Some of the lost energy can be recovered. The thing I would worry about is the constant bombardment by stelar matter. Have you seen/heard about astronauts seeing flashes of light whilst in space.
  13. I designed an all permanent magnet motor a few years ago but haven't the cash to do anything with it but its so simple it won't be long before someone with the cash produces it or something similar. We won't need fuel any more. As for size I thought it would be best to make a one person car that joins to a secondry chassis with the extra room for passengers. Plastics have come a long way now and some exhibit properties like steel. The problem with recoiling panels is that allthough they absorb impact they then recoil with the energy of the impact so it actualy makes it worse. A plastic memory would be good as an after crash repair or make the shape only strong due to its shape so you could easily pop out the dents later. I don't see why air bags aren't used on the outside as well.
  14. What about rotation of galaxies and their grav effect on the path of light. It may be that light from us set off one way and we the other, but, in the vast swirliness of space we may end up heading for the same light and it for us.
  15. By ek tha wor brung up t spoke proper england anall.
  16. If you mean power it the rtg supplies used in these probes. Radioisotope thermal generator. A plutonium 238 slug provides heat to a plate, on the plate is a post of n type material and a post of p type material then on those are cold plates attached to a radiator to keep them cool. The heat plate is solid and the cold plates are like the battery terminals. The n/p materials are semi conductor types like electronic components.
  17. I had a near death experience when my gear box jamed on the motor way. My whole life flashed before my eyes. God it was boring. If you want a picture of me I'll have to put it in the horror storey thread.
  18. Fanny in the uk is a reference to a females genitals. I figured out what the american understanding of the word was watching american tv shows but not before a lot amusement and confusion. What about spend a penny. I worked with a guy who moved to canada for a while, he was a mechanic and he had to relearn all the names for the parts on a car.
  19. Whats it about. Disproving science sounds a bit weird.
  20. You only realy experience g when you are stationary relative to gravity/centrifuge/inertia. Even being slowed by friction you would still be moving with gravity to some extent. An alloy that Thales mentioned in another thread may help as it turns heat into electricity and cools. A good heat sheild and a suit containing this alloy might make it possible. It may take the form of sky surfing. Dude. A board as the entry sheild, wrong shape but you get the idea. Then you would need multi stage chutes starting with small metal ones and working up in size and down in materials. I think a suit of this type would be quite restricting though, the nappy/diaper would get uncomfortable too.
  21. I get what you mean but the light isn't realy moving sideways. Its just like shooting a machine gun. You fire bullets in rapid sucssesion while changing the angle of the gun. Each bullet reaches the moon at the point that its trajectory took it but it does not move side ways. You may have a good particle/ wave experiment though. If you moved the beam fast enough you would get seperate photon impact sites with particles.
  22. The best one is a heavy spiked rotating shell with a floating floor skimming wedge protruding slightly from beneath. Any wedge will be deflected up to the spikes and be damaged. Any other attack will result in damage to the attacker. It will be heat/flame resistant.
  23. Sorry to but in but once you have a biosphere, you could take a larger transparent container and attach your biosphere to one side (inside) using say 10mm spacers and then fill the second container with coloured liquid. Just an idea.
