res10. benjamin franklin did with a key at the end of the kite he flew but lightening dosent last long enougth be be really usefull and it is in the millions of volts and lots of amps

it would be hard to blind someone with my laser as it shines a small bright dot and the pilots being so high up and in the cockpit and there windows faceing on the top forward half of the plane and im down on the ground and with such a small red laser dot , and trying to find the small eyes of a pilot from miles below to blind him with a laser dot so small would be hard unless you are at high sea level and the plane is in front of you in line of sight and you have a bigger wider laser then you may be lucky then

if you need a really good high voltage fuse nichrome heater wire would probably do the job , mmmmmm

have you looked at the high voltage stuff section plenty good information there and you may like a marx generator there pritty good , look at the hand powerd generator topic in the high voltage stuff section where a small marx generator on top of a hand powerd generator really puts out the fats arcs, may yeild a few good ideas

key chain lasers here can be brought for around $5 and they have all these lenses you can use and even they all create all kinds of pictures with the laser, even a cross etc etc and dot and rabbit i have a plastic draw hull of lense attachments that can be used and i choose to use one attachment that the the lense fell out of so i get just a strait dot, of which i need and if i put a plastic tube over the transister of the reaceaveing circuit with relay then i can get the laser to shine into it and no other light from the side will get in

the fine details hey, has anyone gone into the molecular structure of the transistor yet ha ha ha ha and back to roswell where it was rumoured it orinated from as a product of reverse engineering of crashed alien space craft ha ha ha ha

from keychain lasers to spy maps ooh

audio guru what is this google maps thing you can use the keychain laser circuit to relay to get rid of those skunks by rigging a trap door on end of pipe through the relay so when skunk breaks beam its history, or use big lond pipe filled with oil make sure its all oiled up the insides ,the skunk goes in to smell and taste the chip fryer oil or used cooking oil for its smell then it cant get out so it slips into oil at bottom then drowns

:)ante with the positive input from one battery and the negative input from the same battery to the led via resistor which runs through the open or closed relay contacts is just my indication that the laser is lined up with the senser so i never botherd to put any ground as the neg is normally in respect to the ground anyhow, hey it works great uncle ante ha ha ha

hello knowledge is power , that has allways been my beleaf that knowledge is power. look at my ignition coil driver circuits posted in the high voltage stuff section and you can even power 2 ignition coils in parralell to , or if you want big arcs use a high voltage trippler with your single ignition coil , youll see pictures of my ignition coil drivers i biult from circuits ive collected and the modifications ive made to them , and the high voltage dc output tripplers i used

and yet it all works perfect with no over heating, my friend.

:)i forgot to mention the keychain laser dose shine a very long distant in the dark and untill i can find a street long enougth in the dark without any inturuptions i can get a better idea but ive had a keychain laser years ago and the best i can geuss from shineing it down a long road was a quarter of a kilometer or over , no tape measure long enougth to measure that and i think with the keychain laser i have the voltage of the 3 button cell batteries is closer to what ive managed to get with the output from the circuit to power it and somehow i think if there is a max voltage input before the laser burns out then i must be under it and the laser is brighter to

:)corection you say 18 volts not 21 well the 2 batteries aint runing in parralell or sieries and dont have full charge in them ive got them sitting in parralell or sieries but they aint wired the same remember one battery powers the laser in the laser circuit and one powers the relay circuit and the last battery is just wired in through the relay contacts in such a way that when the laser shines into senser the light goes out so that is my indication of perfect laser alignment into senser and when the beam is broken the relay turns on and the led comes on and whatever other circuit i add to it latter

audio guru the circuit that drivers the keychain laser is a regulater with its output reduced to afe level enougth to power the laser, froma 9 volts battery which isent at full 9 volts and the regulater wont allow any more than 5 volts if i had more than 9 volts input, and even if it was fed 12 volts from my lead acid cell batteries it puts out exactly 5 volts and with just the 9 volts battery with under 9 volts left in it i get just the power i need to power the keychain laser without burning it out. as for the receaver circuit or light deactivated realy it tuns off a 9 volts battery to that has less than 9 volts left in it and as for the led thats not runing off the circuit as its only run through the relay contacts from a sepparate 9 volts battery that hasent the full charge and is under it and for the led 390 oms at 1/2 watts is sufficient to power led from a 9 volts battery that hasent got 9 volts in it and theres no heat generated whats so ever , even if the battery had the full nine volts theres no heat i did try another circuit before to get 4.35 volts for the laser but dispte what the circuit said, when i biult it it did not put out what the circuit said it would so i ended up modfying a simple regulater to do it right and it worked from biulding it not from theory or circuit that was probabaly drawn but not tested, as for the 21 volts i think you mentioned where did you get that from im useing 9 volts battery with well under there rateings and the light deactivated relay circuit uses 2 x9 volts batteries and the yellow coloured relay voltage rateing is much higher than what the 9 volts batteries have in them and even the current rateing to and ac rateing to and dispite useing such low voltage the relay is working ok so ill asume the voltage rateings are minimim to operate the relay with the low voltage of well under its stated voltage rateing

:)

here is a closup of the circuit and allso the whole setup of the prototype

:) here are some more pictures in this one is a redraw of the siutable circuit with the adition of the relay which is different the relay here is wired up with a separate 9 volts dc input , so when the keychain laser is aligned with the photo transiter, the led turns off. and ive yet to make some more modification so as to include other circuit aditions so that the circuit can transmitt warnings or alerts ,when the laser is broken

ok ante hey you can light up the rear reflector of a car from a long distance way to

ante the dark activated circuit s relay is kept open by the laser shining into the fairchild photo transister and the transister can be housed in a peace of black tube so no other light can set it off unless it shines into the tube but ive got it set so the laser triggers it only but ill find out for sure next time i do some more testing, the laser keychain shines that red laser spot a really long distance so i just need s ome long distance space to find the maximiun distance the laser can trigger the sensitive realy circuit from and ill add it to this topic first ill need to get a nice size houseing for it all and one long dark street as this one we live in is around 100 meters geussing, long and the laser i can shine down the end and through the windows of a block of flatts so ill keep doing some more testing

if your looking for an infrared activated switch youll find a really simple one in the topic fairchild photo transistor data and if you want to see how simple it looks look at topic keychain laser power supply as the infrared switch or light activated realy circuit that uses the fair child photo transistor allso detects laser at a large distance away

any problems viewing pictures to and you get an empty square with a cross in its corner , just right click in the square and left click on show picture, in the list. if picture dosent show then its another problem, allso if theres no picture then at the bottom of the erea where the picture would of been there would be a jpg thing attachment so click on that to download picture to view , if receaveing any kadack digital pictures and you cant open it , send the picture to my documents in your computer and open it there , as the documents in your computer seems to have the program to open and view these digital pictures

the last 2 pictures aint comeing up so click on the download link at the bottoms to download them to view them and send them to your documents and open them there if you cannot open them

:) heres another view and this time the switch hasent fallen down on its side as i had it held in place with blue tac

hers some more better pictures, in these pictures ive retaped the wireing to the keychain laser and allso ive included the light deactivated relay circuit so when the laser beam to the light deactivated relay is broken the relay switches on and turns on whatever is wired to the relay

with the on button on the keychain laser taped down the on switch is left on and i used a small on off slide switch at the battery clip to switch it on with
