Sputnik Beeper Model remixed after Fran Blanche

thingiverse

Update: I've added a soundfile that sounds similar to the little nasty Nightingale bird before my window. I've extended this thing to become a collection of documents taken/saved from the internet showing the Sputnik1 transmitter in a bigger context. Some of you might never have heard or listened about the thing that started a new chapter in history. The very first thing mankind put into Earth orbit was made in the USSR, not some lame duck created by USA propaganda. Everyone on earth could see it with the naked eye. This is my take on making a remixed Sputnik Beeper Model. It's still in its early stages and will stay Work In Progress for a while. Initially, the Sputnik model with the built-in beeper was made in 1957. It was made from a half Earth globe base part with the tiny Sputnik ball on top stored by the British Museum of Science. See the first picture. The "Public Service Broadcasting" band "Sputnik" music with speech is available at https://www.youtube.com/watch?v=It42TsD7_sI Here are some links to more information: * The real thing: https://en.wikipedia.org/wiki/Sputnik_1 * UN Digital Library: https://unesdoc.unesco.org/ark:/48223/pf0000067963 * Russian webspaceweb: http://www.russianspaceweb.com/sputnik_design.html * History blog: http://www.bbc.co.uk/ahistoryoftheworld/objects/VMQQcaXpRyWtrX7948AfdA Sputnik 1 was the object that began the era of space exploration when it was launched from the USSR in 1957. Many people will remember the wonder of hearing the regular 'beeps' of the radio signal transmitted from Sputnik as it orbited Earth, sounding rather plaintive and lonely. Some people have mentioned that telemetry or temperature/pressure data could be encoded by varying the pulse package duration/pause length. For more information, see the oscillogram in the second picture. Radio amateurs received QSL cards from Sputnik, which is a large size document available at https://www.thespectrummonitor.com/October2017TSM.pdf Here are some models of Sputnik: https://hackaday.com/wp-content/uploads/2017/04/sputnik-e1493067343673.png?w=800 For more information, see Fran Blanche's YouTube channel, where she made a simplified model with the restored electronics circuit. Since she sells her work as a kit only, I started making my own PCB and case design. Some details can be taken from the published videos. Here are some files: * The CNC files (Gerber/Exxellon) are not mirrored. If you need to flip them over. * The STL files represent the very first design. I would like to change the base and top part for reducing the print time. Edit your own version using Tinkercad: https://www.tinkercad.com/things/bshg0Q4fTUs-sputnik-pieper-modell-remake To build this project, you will need: * A PCB, which could be made by hand or even drawn on thick paper or cardboard. * Old Germanium transistors, such as the GI 2N404A. The equivalent for the P6G could be the MP40-series transistors made in the USSR. * A few resistors, capacitors, a tactile switch or tumbler, and a 9-volt battery. * A loudspeaker with low impedance (8 Ohm) and an outer diameter of 40mm.
