Playing a Record Made of Glue
Let It Be by The Beatles, on Mint Condition Glue, played using a pin stuck in a plastic soft cheese container.
I used PVA glue to clean some old records, and after peeling off the cast, wondered if it was possible to play it. It plays in reverse (so I've reversed the video) and the sound from two grooves is audible at once, because on the inverted surface of the glue record, the groove is what was originally the space between two grooves.
I've applied EQ to the audio to make it a little less harsh on the ears, otherwise it's as recorded by the camera's microphone.
(Re-uploaded because this 2nd attempt produced much clearer results)

Stereo OPL3 Music on 2 × SD-1 (YMF825) Chips
zhlédnutí 1,7KPřed rokem
The SD-1 (YMF825) is a "modern" FM synth chip from Yamaha, still advertised as a current product on their web site (as of 2023). It appears to be a descendant of the OPL3 found in many PC sound cards of the 90s. One key difference is that the SD-1 has only a single output channel and can therefore produce mono audio only. Can two SD-1 modules be used together to produce OPL3-compatible stereo s...
Prototype OPL3-Based Instrument
zhlédnutí 1KPřed rokem
A sketchy first hardware prototype of a synthesizer based around the Yamaha OPL3 FM sound chip and Trill Square X/Y touchpad controller. I built this to test the firmware on real hardware and experiment with the UI.
YMF825 Custom MIDI Implementation

I wrote a custom MIDI implementation and GUI patch editor for the Yamaha YMF825 (SD-1) FM synthesizer chip. Here's a quick demo showing some features of the MIDI driver and the SD-1 chip.
OPL2/3 Music on a NEW Yamaha FM Chip (YMF825)
zhlédnutí 32KPřed 2 lety
Yamaha still make one FM chip, the YMF825 (a.k.a. SD-1), which has some striking similarities to the OPL3 used in many PC soundcards in the 90s. I wondered if the SD-1 might be able to play OPL music, and if so, what it would sound like. I built a USB interface and OPL to SD-1 translator, and tested it with various PC game and tracker music - here are the results. Schematics and firmware for a ...
Debian Linux Virtual Machine on Apple Silicon Mac
zhlédnutí 6KPřed 3 lety
This is a quick experiment with Debian Buster running on an Apple Silicon (Arm) Mac in a toy VM app I wrote using Apple’s Virtualization framework. Source code and pre-built Debian images are available here: github.com/danielrfry/toyvm The VM is very bare-bones, basically no real hardware is emulated; only virtio devices. The stock Debian kernel doesn’t include the virtio console driver (it’s c...
Monkey Island 2 with VS1053 MIDI Music
zhlédnutí 1,7KPřed 4 lety
The VLSI VS1053 is an audio codec chip that features a full sample-based General MIDI synthesizer. There are a few videos around demonstrating its instrument sounds individually, but I was curious to know what it sounded like playing back a familiar, high-quality General MIDI soundtrack. I made this video in case anyone else is similarly curious. The setup I used was an Adafruit VS1053 breakout...
OPL2 Music Player
zhlédnutí 2,3KPřed 4 lety
This is a music player I built that has a Yamaha YM3812 FM synthesizer chip* on it, which was used in early AdLib and Sound Blaster cards. Among other things, it plays music from DOS games off an SD card. (* possibly not a genuine one) This device was almost immediately made redundant by the OPL3-based version I made next (czcams.com/video/sowx0vtTxX4/video.html) but here it is anyway for compl...
OPM Music Player

This is a music player I built that has a Yamaha YM2151 FM Synthesizer chip on it. This chip was used in many Japanese computers and arcade games. Among other things, it plays music from arcade games off an SD card. Here is a video of it doing that. Music: 0:03 - Game Start from Pac-Mania 0:14 - Sky from Quartet 0:46 - BGM 1 from Shinobi 1:09 - BGM 2 from Shinobi 1:31 - Continue from Shinobi 1:...
OPL3 Music Player

This is a music player I built that has a Yamaha YMF262 FM Synthesizer chip on it (or, probably more likely, a convincing clone of that chip). This chip was used by the AdLib Gold and Sound Blaster 16 sound cards. Among other things, it plays music from DOS games off an SD card. Here is a video of it doing that. Music: 0:07 - NewSan from MegaRace 0:55 - At Doom's Gate from Doom 1:19 - Introduct...
