Thanks, imatfaal. Hope the efforts from administrators to restore that thread become successful. The original poster has been left in limbo with a discussion of interest.

Evaluate "Track me" from: http://www.luisespinosa.com/trackme_eng.html By having a mobile telephone on board your toy. Or, WIMP (Where is my phone?) https://play.google.com/store/apps/details?id=com.adidsoft.whereismyphonetracker&hl=en

Hi. A few days ago, I replied to a thread and am unable to find it for a follow up. ----> Google does report it, ----> But SFN does not : Suggestions please ?

The aim was not the evolution, but the degeneration. Suggesting that the English evolves by disrespecting it saddens me

Great !

There has been improvements in simplicity, reliability, functionality, durability and efficiency in mechanics, hydraulics, architecture, engineering... from early designs from past years. What parts, joints, geometry, dimensions, efficiency, design in the human body would you like to see improved ?

Rotting English... by laziness. The words 'laboratory'; 'identification'; 'abdominals' are gone ? 'Madam' is offensive ? An apostrophe has to be tossed in ? Female dog ? Three in the afternoon is being called 'night' ? I thought nights started at sunset ! 'Dinner' replaced by 'lunch' -- Isn't that what kids take to school ? Supper. What was that ? A ginecologist is now an alphabet soup. There is no more amplifiers or Amperes, now it is 'amps'... 'Googled' this or that... If you 'search' for something you are saying it wrong... 'Software' ? ; 'Booting up' ? Come on ! News redacted in convoluted phrasing to save ink ? Is a dozen 'you know' per minute the way to talk ? This can continue for pages and pages... and the crowds eager to follow whatever crooked word. Sorry; English is not my first language, but find it degenerating fast and nobody cares a bit, nor efforts are put to demonstrate education. ----> Is there no entity policing the correct use of this language ?

Coincide with arc's suggestion about the location it hooks up to. With the door upholstery removed, place a strong light inside the door and use a mirror to see the mechanism. Murphy told me the nylon clip 17 34 for the rod tip may have fallen inside to the most inaccessible crevice. All efforts exhausted, the other door may provide a sample for reassembly location. Sometimes, there is visual access by removing the external door handle first, which means you will end with two rods dislodged Whenever you become an expert on the task, you are welcome to do it in my LandRover... twice.

That is unusual. It has worked for me fime testing ignition coils, several times, jumping a spark across the spark plug. What is the measured AC voltage on the primary while energized ? Plan B : Get an automotive relay and connect its common and normally closed contacts in series to your 12V DC battery source. It will provide a faster turn-off. Let me see if I find a schematic for your better understanding... +12V--------------C---/ .----NC------------coil primary-------------GND NC------------relay coil----------------GND In other words, both coils in parallel betwee the NC contact of the relay and battery minus. But remember the spark plug thread must be connected to the secondary or common, whatever your coil has. Here is something : http://www.popsci.com/diy/article/2009-12/shocking-truth-how-make-high-voltage-sparks Come back with results. If you cannot make it work and short on time... try a gas stove spark module, available from most discarded ones or at the appliance parts store.

Some clever development shown here : ---->

Transformers run on alternating current. That ignition coil is a transformer. What you heard does not matter. Nothing to elaborate; D O I T !

Come up, bring your explanation. ----->

You need to read this and its embedded links along the paragraphs... -----> http://amasci.com/miscon/whatis.html

MMK: The coil 'metal body' for that Suzuki one is still its non-insulated metal body iron core, as the bracket seems insulated on rubber mounts, or one of the primary terminals is also common with the secondary. It has to connect to the spark plug thread. To see pulses on pin 3 you need to use an oscilloscope. A DC volt meter will not tell such, will show high or low depending on the oscillator status, or somewhere in between for AC scale, which may kind of detect/read the oscillation. If the contraption is not going to operate in a vehicle, you do not need to make it work with a 12 Volt battery nor the oscillator circuitry. Pick a 'wall wart' 120VAC to 12VAC transformer and connect your coil primary to it, nothing else. Watch were you put your fingers or you may get the jiggles.

Is the ignition coil metal body connected to the spark plug thread ? You need to probe for pulsing at pin 3 and bases of transistors.

Abrasion of the skirt edge. It does make contact with rough soil surface. The smoothest ride is on a frozen lake. Smooth land is more efficient, as the soil does not deform under the craft as water surface does, making it more concave at lower speeds. Riding on an even slightly inclined pavement makes very difficult to maintain heading. A calm river is a very pleasant ride. Find somehow to ride on one, and you may get hooked. And do not bring the throttle down on fast turns ! You may rollover ! It will be noisy and wetty...

Yes, the skirt is part of the hovercraft; contains the air pressurized by a fan blowing into its plenum. The fan inflates it, stretching its height to the limit and raising the vehicle because of the pressure built-up. At the limit of rise, air escapes. The dust/mist is caused by the speed the air escapes between the gap, between the skirt bottom and the riding surface. The smaller the gap, the faster the flow. There is mild abrasion as the skirt bottom contacts the riding surface bumps. ---->

Superb ! A ~100 year old traditional folkloric tune in modern technology and your great skills. Thanks again---->

All right all you trekkies, here it is, the ultimate gift!

Thanks a million, Daedalus, very nice of you. The other song is of no interest, but thanks for asking. I tried with an online 'Noteflight' program and got half way, good you came to the rescue. I will somehow listen to it in another compfuser later, as "Murphy lives with me" and Linux refused to play beyond the first note Has to be some default tweak that I have to check... "If anything can go wrong, it will" Edited - added : Well, Murphy has been defeated again, heard it perfectly with no tweaking, no problem. Was just a compfuser hiccup... -G R E A T !!!-

Many things have to be considered... What is the current power you are using ? What is the distance wanted to reach ? Is there line of sight between units ? Will it be 2 way communication ? If yes, you will have to amplify the transmitters at both ends. Have you tried by using high gain directional antenas instead of amplification ? Here arew some links of interest: http://www.abacom-tech.com/%2F433MHz-RF-Power-Amplifier-PLA-05W-P93341.aspx http://www.flytron.com/openlrs/108-7w-booster-for-uhf.html You may find kits too.

Hi. Just found a partiture of a song my grandfather used to sing when I was a little kid, but no music. I would like to beg any musician to play (perhaps piano?) and capture its mp3 for me to listen. It will bring tears to me, meaningless to any other. If within your skills, please try. Attached. Thanks

This is not about volume collection ; it is about efficiency. Read again. If it was about volume, bigger simply collects more.

The propagation speed of the electrical signal depends on the cable contruction and its dielectric. That far away bulb takes two conductors to circulate a current trough it. The speed can be somewhere between 60% to 99% of c. ----> http://en.wikipedia.org/wiki/Wave_propagation_speed What I cannot discern is if the total wiring lenght being 2 x 900,000 Km = 1,800,000 Km long; the light bulb will turn on when the wave reaches it or when the wave reaches the return starting point * [All this assumming perfect ideal theoretical conduction] If c is 300,000 Km/sec, and the propagation speed over the wiring is 66.666 % , the actual electrical signal propagates at 200,000 Km/sec For a 900,000 Km trip, would take 4.5 seconds. * If the 1,800,000 Km round trip has to be considered, would be 9 seconds. I think
