Together with a friend of mine we planned for quite some time to recreate a mod for the creature from the black lagoon CFTBL. The hologram always looses in structure so over time, the optical effect is gone.
There couple of mods in the past, most noteworthy the one from PinballMike. As creator of TILT!Audio* and Co-Author of pin2dmd, there was a long lasting wish to control additional hardware based on a serial control signal coming from pin2dmd or RasPiSound, which got its first application now in this CTFBL mod.
The incredients are:
- TILT!Audio* for CTFBL with latest firmware version 1.16 or newer
TILT!Audio* you may know already is a sound card replacement for data east or wpc machines based on a raspberry pi is introduced here:
Serial-Media-Server is a relatively simple project also based on a pi3 with raspbian stretch lite, omxplayer and a python server. The sound hardware communicated with serial-media-server via a serial line at 57600 baud 8N1.
Combining the two requires two serial wires and some software configuration. The basic steps are always:
- Define a serial command for a sound effect, that is send out each time the sound is triggered.
- Define a media file, that serial media server should play / show on a specific command.
How is this done?
Serial command are just numbers. To send out a command with a sound effect just create a file „serial.txt“ in the sound effect directory and write a number in the first line.
On the data directory of the serial media server create a file like <number>.mp4 or <number>.jpg and the file gets played / shown.
Sounds easy? It is easy.
How will it look like?
A friend of mine did a demo with his CTFBL machine:
Also note that there’s all playback content for CFTBL included, if you choose the full CFTBL-serial-media image. See here.
TILT!Audio* is a DIY project but I sell kits to build one in my shop. Depending on the feedback for the new CFTBL mod, I may also offer kits for the that (display mounting basically). Software is already provided as mentioned above.
*TILT!Audio is the new name for RasPiSound
