"Here we have a custom circuit bent Texas Instruments Speak & Spell.

Operates as a totally normal speak and spell until you flip a glitch switch or turn a dial, etc.

Very fun to play, no right or wrong way to it, this bent talking synth is capable of tons of new sounds for you to record, sample or play live.

The added mods include:

1) Tone Oscillator button-creates a tone when depressed, the tone can then be manipulated with the theremin pitch cell, pitch dial or pitch body contacts.

2) Active Matrix Glitch-This mod opens up the membrane for random glitching dependent on where you touch the pad.

3) Ramble Glitch-Flip this switch and hit go and it will spew constant ramblings on and on and on and on.........

4) Dual voice glitch- causes it so speak In both a high and low voice at the same time.

5) Pitch Changing Body Contact-Touch this to lower the pitch, the harder you touch the further the change.

6) Pitch Changing Knob-Use this pitch control to change the pitch from incredibly high falsetto to super low, 8-Bit crushing growl.

7) Reset Button-Use this when you're ready for a change and the machine is rambling on its own, also serves as an OFF button.

8) Theremin Opto Cell Controller-Simply flip the switch, use the pitch dial to fine tune and you can play any sound emitting from the speak like a theremin, makes for some great effects.

9) Loop Switch with Advance Button-FLip this switch at any time to catch a sound that you can then mold and play with the other controls such as the opto cell and pitch dial.

10) Strobing LED for cool effect

It now features a 1/4" output jack that mutes the onboard speaker, allowing you can output this into your effects, amp, pa, etc.

the enclosure design made by me you can go inside change battery on anything else just unscrew 4 screws

Häxa - TI-82 Houstontracker Jazz


video by tubesockor

via @tubesockor

"The jazz drummer Lars Skoglund (La La Lars) released his latest single "Häxa" as sheet music and then let other musicians make their own versions. Here's mine - done on a Texas Instruments TI-82 calculator from 1993.

The calculator doesn't have a sound chip, instead it is using delicate bit flipping on the communications port to make audio, using the tracker "HoustonTracker 2". I've made a previous video about how that works, which includes my cover of the C64 song 'Warhawk':" [posted here]

Warhawk [C64] music on TI-82 Calculator - HoustonTracker 2


tubesockor

This one is in via @tubesockor

"This is a TI-82 remake of the Commodore 64 soundtrack for the game Warhawk, originally composed by Rob Hubbard in 1986. It is programmed down to the deepest details on a Texas Instruments TI-82 graphing calculator using “HoustonTracker 2”.
I start with a tech dive into how sound is generated on Commodore 64 and the TI calculator (which doesn’t have a sound chip) as well as 1-bit music in general. Then the song appears, including a custom-written visualiser that I made.

0:00 Welcome
0:20 Commodore 64 & SID

1:27 1-bit audio on TI-82
2:04 Pulse Interleaving

Update via the comments: "based on the 3 switch 'Mixer' and the mixer truth table hand written on the back of the device, it looks to be based around the TI SN76477/SN76488 sound chip"
