Saviour is a hack that we are very proud of building this tool because it can really help people in times of emergency.What we learnedWe learned with help of simple components, such as the potentiometer and button we can create such a good graphical interface. Thus bringing a mere project idea into life and that too in very little time is what we are very happy about.
#Altium designer pcb without schematic code
Displaying the morse code and listening to the buzzer to beep in accordance was a very proud moment. We are really proud to have overcome all the challenges like making the interface, making the FM transmitter. Printing the translated Morse Code on the OLED was a bit tricky too.Accomplishments that we're proud ofWe were in a bit of a time crunch since a lot had to be done, but we decided to work on one aspect at a time and finish that first. Stopping abnormal flow or increment of button pushes using flags. Now all these interfaces are displayed over an OLED display, and all of them get controlled by the Arduino.Challenges we ran intoMaking the interface was a bit tricky. Those get parsed and fetch the coordinates and finally get transmitted via the transmitter. As the name suggests, this part contains a GPS, through which the NMEA data is received as packets. Last but not least, the life saviour, the GPS. Its job is to transmit the Morse code over open Air. After that, a simple single transistor FM transmitter was built using a coil, capacitor, and transistor. The buzzer plays the Morse Code with a Farnsworth speed of 10 in sync with the LED flashes. Next, the Indicator was built using a small Buzzer and a LED which can also be used for signaling, and it is still considered to be an effective way. The potentiometer, scrolls through the characters, and the button increments the cursor. To create a sentence, we reused the same button and the potentiometer. According to the supported Characters, the program translates it to a Morse String. The Morse code translator is built by parsing the String sentence character by character and creating its Morse equivalent. This is done by a potentiometer to scroll, and a button to select. Firstly we created a menu-driven Graphics Interface for choosing the mode, whether the Morse Code or the GPS. This hack is not only a very important tool that will come in handy for people going on a vacation or traveling because of work purposes but it can also be used as an educational tool for learning Morse code since it has a Morse Code translator.How we built itSaviour has four main parts - one is the Morse Code translator, indicator, transmitter, and the GPS. This will make it a lot easier for the search party to find the lost individual thus speeding up the process of the rescue operation. the latitude and longitude of the signal's origin location using the GPS. So with that not only Savior can send the SOS signal using radio, but Saviour sends the location details i.e. Since GPS satellites revolve all around the world, they can connect and get your current location. Now, it also contains a GPS that can get your direct coordinates. It also has a buzzer to sound, how the Code will sound. It also has an OLED display, that can translate any sentence to its Morse Code, and display that code on the OLED simultaneously transmitting the code over the air, and also flashing it via a LED. Saviour uses Morse Code signaling via a radio transmitter, also with a LED. If one gets stuck in a deserted area, say on an island or some mountain, where the Mobile gets useless, due to no network coverage, radios are still there, which can be a very effective way of communication in that scenario, and still, they are used all way. Saviour can do radio signalings like the popular SOS signal or any emergency signaling.
The idea behind Saviour was to create a hack that allows people to travel to remote locations without having to worry about getting lost or getting stuck there.What it doesSaviour is an emergency tool that is very powerful, in times of real juncture. where the protagonist gets stuck on an island, even though it sounds very adventurous, but nonetheless the dangerous probability of it happening in real to people still remains.
