IFComp - Interactive Fiction Competition Retro Challenge RC2018\/04 in April... ...and 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.  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.  Reed-switches and magnet forming a simple encoder, and the magnetic element to emit audio towards the tape-player's head:    Testing the tape inside a pretty tape-player:   Signals from both reeds-switches. By observing delays, frequency and phase-shift, the software can process game-input:   Tetris'ing electrical components within the tape's enclosure: Testing the toaster. Cold-spray, stopwatch and 2 thermocouples:   The actual "circuit". No idea what the pink wire was for. "M" is the heater specifically for the bimetallic strip, and "H" is the main bread-heater: ","author_name":"CBA Podcast","author_url":"http:\/\/podcast.cba.si","html":"
