IFComp - Interactive Fiction Competition Retro Challenge RC2018/04 in April... ...and&amp;nbsp;my entry for the RC2018/04 Outline demo-party (10-13 May) Hackalot: upcoming hackerspace in NL For the upcoming IFComp, I want to make an interactive cassette-tape, where the tape-reel is replaced by software driving a magnetic element to emit sound/speech, where the user interacts with the game by pressing fast-forward/rewind/play/stop on the tape-player.&amp;nbsp; The project will thus consist of a reworked cassette-tape adapter (fitted with electronics) implementing an adventure-game. Let's create the actual game within the IFComp contest-period, and make the hardware-platform in advance - as in, now.&amp;nbsp; Reed-switches and magnet forming a simple encoder, and the magnetic element to emit audio towards the tape-player's head:&amp;nbsp; &amp;nbsp; Testing the tape inside a pretty tape-player: &amp;nbsp; Signals from both reeds-switches. By observing delays, frequency and phase-shift, the software can process game-input: &amp;nbsp; Tetris'ing electrical components within the tape's enclosure: Testing the toaster. Cold-spray, stopwatch and 2 thermocouples: &amp;nbsp; The actual &quot;circuit&quot;. No idea what the pink wire was for. &quot;M&quot; is the heater specifically for the bimetallic strip, and &quot;H&quot; is the main bread-heater: CBA Podcast http://podcast.cba.si <iframe title="Libsyn Player" style="border: none" src="//html5-player.libsyn.com/embed/episode/id/6429054/height/90/theme/custom/thumbnail/yes/direction/forward/render-playlist/no/custom-color/88AA3C/" height="90" width="600" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe> https://assets.libsyn.com/secure/item/6429054
