Sometimes a mix of old and new is better than either the old or new alone. That’s what [Brad Carter] learned when he was given an old 1990s sound board with a noisy SCSI drive in it. In case you don’t know what a sound board is, think of a bunch of buttons laid out in front of you, each of which plays a different sound effect. It’s one way that radio DJ’s and podcasters intersperse their patter with doorbells and car crash sounds.
Before getting the sound board, [Brad] used a modern touchscreen table but it wasn’t responsive enough to get a machine gun like repetition of the sound effect when pressing an icon in rapid succession. On the other hand, his 1990s sound board had very responsive physical buttons but the SCSI hard drive was too noisy. He needed the responsiveness of the 1990s physical buttons but the silence of modern solid state storage.
And so he replaced the sound board’s SCSI drive with an SD card using a SCSI2SD adaptor. Of course, there was configuration and formatting involved along with a little trial and error to get the virtual drive sizes right. To save anyone else the same difficulties, he details all his efforts on his webpage. And in the video below you can see and hear that the end result is an amazing difference. Pressing the physical buttons gives instant sound and in machine gun fashion when pressed in rapid succession, all with the silence of an SD card.
A SCSI2SD card is a nice off-the-shelf solution but if you want something a little more custom then there’s a Raspberry Pi SCSI emulator and one which uses a Teensy with a NCR5380 SCSI interface chip.

Ayn Rand said, “If it’s worth doing, it’s worth overdoing.” As far as we’re concerned those are words to live by, and something that’s exemplified by most of the posts on this site. She also said some really suspect stuff about the disabled and Native Americans and reality, but you’ve got to take the good with the bad and all that.
We don’t know how much Rand [Will Weber] has read, but we’re willing to bet he’d agree about overdoing it. He recently documented a very cool 3D printed tap handle that’s designed to look like the B8 flight stick from an AH-1 Cobra helicopter. But this is no static piece of plastic, in the video after the break, he demonstrates how each button on the flight stick triggers a different weapons sound effect.
The 3D print is separated up into a number of sections so that the stick can be assembled in pieces. Not only does this make it an easier print, it also allows for the installation of the electronics.
For the Arduino aficionados out there, we have some bad news. Rather than putting in a general purpose microcontroller, [Will] went the easy route and used an Adafruit Audio FX Mini Sound Board. These boards have their own onboard storage for the audio files and don’t require a microcontroller to function. It makes it super easy to add sound effects or even music to your projects; just pair it with a power supply, a couple of buttons, and a speaker.
The finish work on the printed parts looks excellent. We can only imagine how much fun [Will] had sanding inside all the little nooks and crannies to get such a smooth final result. While some might complain about the idea of a tap handle needing to be recharged occasionally, we think the satisfaction of firing off a few rockets every time you grab a glass is more than worth it.
While this isn’t the first unique tap handle we’ve covered here at Hackaday, it’s certainly the most flight-ready. Continue reading “AH-1 Cobra Tap Handle Pours On The Fun”
