Session #1

Prototype #1:

Introduction of main interests:

• interested in the meaning of using obsolete tech today: revisiting and explore it's potential instead of discarding it
• 'Zombie media'
• main interest in low-tech: reveal inner workings (transparency)
• implement it in today's workflow (audio/visual, programming, etc)

• Side interest: lo-fi music production and post-digital publishing
• Interested in working with limitations.
• creating workflows that reflect on what we use today

What I did:

• came across an DIY open-source project
• creates old calculators into 1-bit music composing tool (instrument)
• uses the binary output of TI-calculator to produce 1-bit sound
• 1-bit sound: on/off (real basics of electronics)
• Program ([Houston Tracker)] is still not being used so much.
• Bought the necessary stuff to get it running. (very flimsy, hard to install but it worked)
• uses audio input to load software (written in BASIC, same as C64)

***Demo: Wanna hear a 1-bit chord?***

So, that worked. Let's speculate about the publishing/sharing possibilities: To spread this project and both music, I thought about making a publication/release/demo in one.

Not only for the music as an artist but also to spread the word about this project:

I would write a 4 track album for it and release it on a TI-83.

People that buy it would receive a TI with the tracks on it (collected from thrift store / Marktplaats)

mail it to people

If interest arises:

hands-on hardware to get started.

See how tracks were produced might get people started

enlarge interest, spread the word & expand community?

This way, the public can not only listen but also directly engage and get their hands dirty if preferred. What I also think is interesting that in contrary to making music with the sound chip of obsolete gaming consoles is that it's much further detached from retro aesthetics. So it focuses much more on the tech part and thinking how to use this device otherwise.

TiLP is a linking program for Texas Instruments' graphing calculators:

HoustonTracker 2 is a music editor/sequencer for the Texas Instruments TI-82, TI-83/82STATS, and TI-83+/84+/SE. It allows you to compose and play multi-channel 1-bit music directly on your TI graphic calculator:

Hackpact #2: Home school prototyping

TI-83+ calculator experiments:

• 1-bit music programming and playback (using HT2)
• materializing binary data + sound of the CPU
• recording on cassette tape (digital to analog processing)

playful ideas & potentials to further explore:

• publication to make 1-bit sound
• implementing graphics: bitmaps
• How to embed this in a modern context? What's the use?
• BASIC programming language

SSTV (Slow scan television) experiments:

• materiality of data via sound
• 'slow' data transmission (in contrast with invisible processes and speed)
• encoding /decoding: deconstruction of data
• both interests combined: lo-tech graphics & sound!

playful ideas & potentials to further explore:

• IRC bots that send audio signals you can receive with your phone!
• Instagram offline broadcasting
• broadcasting images over Spotify
• music & SSTV data combined? https://www.youtube.com/watch?v=tJ2X6HmW49E

classic processes revisited, reveal inner workings, material connection, future of 'Data-over-sound', regaining autonomy, networking, encoding/decoding, obsolete data transmission techniques,

Deconstruction workshop: materializing data over sound

• recording sound of a deconstruction process: transfer to the physical carrier (analog tape)
• recording data of images: broadcast SSTV signal
• material combined in audio-visual performance

main question:

How do people interact with these processes?

How is this sonic fiction (http://www.soundstudieslab.org/sonic-fiction/) element used?

PI: Selfhosting IRC + bot

Sandbox as a publication:

• showing where it is! (this is where you are!)
• what happens when you visit (exposing a process with the emphasis on materiality)
