Learn Morse Code

I saw a number of instructables on how to build various kinds of telegraphs, and one including a mapping of characters to either left or right, according to the number of dot's and dashes required to represent it. however, i am missing an instructable about how to LEARN such code. so i've been thinking. it's what i do some times. and i came up with this idea. i am searching for a software that would present you a blank screen. then a letter should appear on the screen, and a sound of the corresponding morse code should be heard. a couple of times. then the same with another letter. next, random letters should show up. the newer they are to the viewer, the often they should be shown and played. after some time, words should appear letter by letter, while playing them. and so on. can anybody help me finding such a piece of software? can anybody make such software?

auto generating morse code device

Need ideas on building an auto generating morse code signal for a geocache I'm building. The idea is, a user will plug a battery into the device and as long as the battery is plugged in the device will emit looping morse code message either with sound or light, preferably light. Thanks for any ideas!

Arduino Morse Code decoder?

I want to make an arduino morse code decoder, which will print the result on a 16x2 LCD. The input will be 3 button, 2 will be the "_" and "." respectively, the 3rd one will be the "space" button, when press will decode the code which was input. If input was wrong then it will display a "?" mark. And it should be able to decode many character at once. Anyone have some idea or code about this? I'm just getting started with microcontroller for about 1 months so I have a bit of knowledge about how they should work, but this prove to be quite challenging for me

How do you test effective range, resistance and bandwidth for the morse code telegraph by johnnyrockstar?

I have made the morse code telegraph machine and need to test the effective range, so I have to work out the resistance and how far apart the bases could be to still work.  I also have to test the effective bandwidth.  Can anyone help me with how i go about doing this?  I would really appreciate any help.

Punched Cards Rebirth project help? Answered

I'm kinda relying on instructables lately, hmm... We have this project with my friend (not just in 'ibles), nutsandbolts_64 and we are trying to relive the past and do some stuff from the "mechanical computer" era. He did aperture cards as he wanted some form to store blueprints and stuff, i'm doing paper punched tapes. I decided to use the 2 hole tapes, the one using the international morse code system. As with many projects, i have a few problems that you may help me with: Is 10mm(w)x1000mm(L) made out of cut and spliced A4 paper good enough for that purpose? Do i still need to punch the holes in the center? (the guide holes thingy) Will a regular needle be thick enough or do i need to get something thicker? (I'm gonna punch it manually, so a needle would be easy to handle) What kind of switch can i use to "read" the data electronically? (I'll pull it manually, no need for a motor) Just in case someone has done his, can you please share your photos? Best answer will get a patch!!!!!!!!!!1!!!!1!!!1!!11!! joke, I'm not a pro member XD Thanks in advance

Aduino Bluetooth code problem!

I am building a Morse Code machine with bluetooth functuonality.  It is in the early stages at the moment but I have hit a problem. My code uses a button to input Morse code which is displayed on an LCD and flashes an LED on pin 5, but also incorporates a bluetooth HC05 which controls an LED on pin 13. Seperately, they work fine but I wanted to merge the two sketches. I have succeeded but for one small problem. When pressing the LED 'ON' button on my android app, the LED only comes on after the Morse code button has been pressed. And it works the same way for the LED 'OFF' function on the app. Press it, then press the Morse code button and the LED switches off again. This repeats. I cannot figure out why this button is controlling the Bluetooth LED command signal. I have changed baud rates of the bluetooth but to no joy. I have attached my code. Can anyone help me solve this problem?!?

Is there something going on in my head? Answered

     Well, I don't have a mental problem or anything, but it often gets weird and I just can't help but to ask. I'll recount several months before, around March or May last year. I was practicing Morse code, practicing with visuals, practicing with audios. After a few weeks of practice, I started hearing Morse code in my head, as in out of nowhere I literally hear it (completely random, it's not spelling out anything last I checked). I asked around about it (deleted the question though) and someone mentioned it's not normal/it's rare. Then fast forward into around November or December, I keep hearing that Morse encoded "SMS" ring-tone from a phone (it's quite popular here, heard it more than a thousand times). I kept searching for that cellular phone, but to no avail. I covered my ears with pillows, and I still kept hearing it. I then concluded that it was in my head. The end result was I couldn't fall asleep for 3 hours lying down on the bed. It's something like LSS (Last Song Syndrome, search it up if you don't know it) to the extremes (to the point that it resonates in your head and you can hear it as an audible tone not from your thoughts). Any thoughts as what may have been causing this?

starting circuit for programmable sequence, for flashing LED?

Hi- I am interested in suggestions for starting points to build a programable flashing LED.  The intervals of dark/light should be configurable, kind of like morse code.  But not subject to what I recall as requirements for Morse- dashes are 2x as long as dots, or something- duration will vary for both.  Maximum total length of sequence is 10 seconds. There are a lot of flashing LED circuit Instructables, some very old and referencing 7 yr old chips- unsure if I can get those chips. In an ideal world, when I am done, I could have multiple EEPROMs that I could switch out to configure the flash sequence I wish.  One sequence per EEPROM.  Or another means to accomplish this. My background:  I can solder a little, I can program and shell script a little, I have not much idea about electronics at all. Thank you for pointers to a jumping-off spot for me!

GPS position transmitter? Answered

I am an aspiring pilot and would like to build a Personal Locator Beacon. I want an arduino type setup that would take my GPS data and transmit it every few minutes for 5 or 10 miles (or more depending on the legality) to a receiver that displays my last known position, my distance away, and my direction (from the receiver). Is this possible? It would also be nice to transmit my position via Morse code too in case my receiver was broken or could not be found.

Is it possible to build an AM radio transmitter with only discreet components?

I don't need to have it have good quality. I'll only be sending morse code, so I don't need any type of audio clarity. If it's possible with discreet components, can you provide a schematic? If not, could I use a 555-based circuit? Again, schematic please. Thank you! (For anyone who doesn't know, discreet components means no IC's , otherwise known as "chips".) EDIT: I'd also like to not use a crystal osscilator. Thanks!

Machine Age Satallite compact flash player

Hello everyone I am presently building a Machine Age Satallite for our Rocket Room exhibit. I want to put at least ten different sound files into it as an added feature. I have several files on a compact flash card--Morse Code, space sounds, etc.. What I would like is a simple programmable player that I can loop and will start playing when the power in the room comes on in the morning. The satallite will be mounted up high so a remote to change the file playing would be nice. I have found kits online that cost about 80 dollars. The price is not to bad but I wanted to know if there was a more clever way of accomplishing this. Thank You Parker

If I use the serin command where is the serial data stored? Answered

 I am trying to get a GPS module outputting NMEA sentences in ASCII through a serial port to to store it's once per minute output in my picaxe 18X. From here i hope to read these sentences and using a look up table assign each letter or number that has been read a morse code form. This will then be sent to a 433mhz radio module and received on a scanner. I have programmed standard pics before but only using standard inputs and don't really understand where or in what form variables are stored on the picaxe chip so am therefore a bit confused as to how to go about using the serin command. Thanks for any help!

Ideas for making simple LED Flashlights, about 6 inches long?

I am wanting to create several (about 20) custom LED flashlights that could be attached to key rings. They would need to be long and tubular in shape, about 6" long, and with a button switch on the back so that the LED is lit when the button is pressed and held, and turns off when the button is released. This would be so you could blink the LED easily on and off manually; like if you used it to send a Morse code signal with the light. Battery powered; most batteries like coin batteries or up to a AA would be fine with me, as those will all fit easily in size. I plan to create the body of the flashlight out of polymer clay or another durable craft material. It would be a unique shape: a column made of colorful geometric forms. The inside could be made cylindrical to better fit the battery and other innards, though. The chapstick flashlight seems to be the closest thing to my purpose here; I am just unsure of how to extend that concept in length to be the same diameter but a few inches longer since the chapstick was the length of the battery! I've also considered buying an LED flashlight or two and taking it apart to see if the insides of it can fit inside a longer flashlight body (maybe it just would need extending of some wires? I don't know). I've been reading up on the LED instructables here. I've never soldered or built a circuit, but I am ready to learn! Any ideas you could share would be very helpful. Looking to get these made this month for an event. I am a technology-building beginner here, so speak slowly!

electronic/mechanical/ LED-Radio-Decoder Wedding rings?

Hey there,my future wife and I are looking for some fancy wedding rings. Well, we're both geeks, so it should be something that involves electricity or a nifty function ;-)Unfortunaly she's allergic to some metal components often used in steel or gold/silver, so titan or something like that would be more suitable. Aluminum or some plastics would work too, i guess.Thats the problem right there. Even if we'd find something online or a store that makes rings, they'll probably not work with titan since its harder to work with.I found some LED rings at as allways the problem is the metal and of course power.A battery would either have to be replacable or rechargable ;D (capacitor? but even a low current led wont even flash up with a tiny capacitor?)A solarcell so tiny it'll fit ontop of a ring without looking redicoulus would not be efficient enough I'dd guess.Of course, as previously stated, it could be something mechanical (as;[4]=30&products;_id=1297 for example)A nifty idea would be if the rings would actually do something when brought together (magnetism, induction, mechanism).I also had the idea of the rings morsing the date every few minutes on radio, much like all fails we'll just look into something cool to engrave (there are rings with laser engraved fingerprints as example) or we'll just embed a electronic part such as a resitor with a value representing the day we've met or such.ANY (cool) ideas apreceated, especialy about LEDs, sources/shops, adresses to shops customizing, and so on (but please, nothing over 50-200 bucks, we're not rich).I hope you guys / gals dont start to laugh at us now. We cant help it. We just want something unique and not a golden ring with some diamond. Some people really have rings that look ugly! Well, geeky LEDs do too, but at least they do something ;-)

Google Celebrates 57 Years of a Great Invention

Google's new picture depicts a barcode saying "Google" to celebrate 57 years of the bar code. For a brief history from Wikipedia about the barcode;"In 1932 business student Wallace Flint of Harvard Business School wrote a thesis promoting an "automated grocery store" using punch cards, which customers would hand to a clerk, who would load them into a reader, causing flow racks to deliver the desired products, after which an itemized bill would automatically be produced. In spite of its promise, punch card systems were expensive, and the country was in the midst of the Great Depression, and the idea was never implemented.In 1948 Bernard Silver (1924 - 1962), a graduate student at Drexel Institute of Technology in Philadelphia, overheard the president of a local food chain asking one of the deans to research a system to automatically read product information during checkout. Silver told his friends Norman Joseph Woodland (1921-?) and Jordin Johanson about the request, and the three started working on a variety of systems. Their first working system used ultraviolet ink, but this proved to fade and was fairly expensive.Convinced that the system was workable with further development, Woodland quit his position at Drexel, moved into his father's apartment in Florida, and continued working on the system. His next inspiration came from Morse code, and he formed his first barcode from sand on the beach when "I just extended the dots and dashes downwards and made narrow lines and wide lines out of them." To read them, he adapted technology from optical soundtracks in movies, using a 500-watt light bulb shining through the paper onto an RCA935 photomultiplier tube (from a movie projector) on the far side. He later decided that the system would work better if it were printed as a circle instead of a line, allowing it to be scanned in any direction.On 20 October 1949 they filed a patent application for "Classifying Apparatus and Method", in which they described both the linear and bullseye printing patterns, as well as the mechanical and electronic systems needed to read the code. The patent was issued on 7 October 1952 as US Patent 2,612,994. In 1951 Woodland and Johanson moved to IBM and continually tried to interest IBM in developing the system. The company eventually commissioned a report on the idea, which concluded that it was both feasible and interesting, but that processing the resulting information would require equipment that was some time off in the future.In 1952 Philco purchased their patent, and then sold it to RCA the same year. In 1962 Silver died in a car accident."Full story about Google's choice of picture here here.

Detecting Very Slight Tendon Movements In Wrist

I've always had an intense fascination for lucid dreaming. Finding ways to communicate or control outside devices based off the slight body movements that are possible despite the natural paralysis during sleep is a topic of great interest to me. I have several LDs (lucid dreams) each night and through much experimentation have found that with a bit of concentration, I could move my fingers enough to trigger very sensitive buttons (if placed perfectly before falling asleep) or to grip myself (if my hand is placed say, near my neck before intentionally entering a dream from waking) such that the sensation of my fingers reaching my neck would wake me. These experiments were proof enough that if I perhaps had some sort of glove or wrist mounted piezo sensors that are able to detect the individual tendon/finger movements with high enough sensitivity, combined with software that can parse patterns and reliably filter out minor unintentional simultaneous movements for the fingers that are prone to movement when others nearby are moved, it would be possible to establish one way communication with outside devices, the Internet, etc. Input could be in the form of different patterns or even text (tap code, morse code, or through a hybrid allowing use of each digit of the hands) or musical notes (each finger representing a note of a scale with a finger or two used to change octave or to toggle sustain.) As a musician who "writes" his best music within his dreams, this could be quite handy for getting melodies down before they vanish from memory on waking. For example, to activate input, you could perform a simple pattern that is unlikely to be triggered unintentionally. It could be as easy as left thumb flex, right thumb flex repeated in that order several times. From this point, you could use another pattern to choose to trigger an alarm (sound, vibration or electrical shock), or to initiate musical or text recording. There are many different uses that could be explored, and it might even be possible that 2 way communication could be established if a reliable method of transmitting to the dreamer without waking them could be created. This is however beyond the scope of my intentions. I have suffered from sleep paralysis on a nightly basis for over a decade now which can be extremely frightening and last up to several minutes, and during this time I am able to move my fingers as well as shake my head back and forth (which I need to do to break out otherwise the paralysis will persist until I'm pulled into a nightmare.) My solution to these terrifying experiences was wearing a heart rate monitor with an alarm that goes off past a certain BPM, which only happens when I am frightened. Now that I am so used to these experiences, my heart rate does not increase enough that I can reliably use it as a trigger without also waking myself out of exciting dreams that I'd rather not have prematurely terminated. I am fairly confident that a device such as this could help with breaking out of my paralysis at will and PERHAPS even be sold commercially to other sufferers of this condition, however niche the market. Giving me control over my sleep paralysis alone would be a highly satisfactory result with significant quality of life improvements and be worth the effort of building this. Waking up partners in bed with my head thrashing is less than ideal! As an avid software programmer, I do not think that the code involved would be terribly difficult. However, I have very little electrical knowledge and building this without existing plans would be tough and time consuming. It would be enough to have a pressure/flex voltage for each digit transmitted to a Raspberry Pi or via Bluetooth to a computer and the rest could be done through software. My questions are.. Does a commercial device exist that would be suitable for my purposes and not be terribly expensive? Perhaps a glove? Is a wrist strap with piezo sensors over each tendon that control the fingers a realistic possibility to achieve my goals? I do not need to know the position of the fingers or whether it is pushing against something. Just that movement is being attempted. Do existing plans exist to create a similar device? Thank you!
