Up one level

The DSP-96 was the second board I designed at Ariel Corporation using the Motorola DSP96002 chip (the first was the dual-processor MM-96).  If memory serves me this was introduced around 1991.  It was also t...

 

I did the DC-4 at Ariel in about 1992.  It stands for "DON Carrier" since it held four DON modules.  Each module had four AT&T DSP3210 processors and 4MB of shared DRAM, and a 32+32 data/address bus whic...

 

This was Sonorus' flagship audio board, released in 1996.  It was the first PCI card with an ADAT interface.  Actually, two of them. At the time I realized there was no inexpensive way to get audio from an ...

 

Bob Tudor, then VP of digital audio products at Mackie, called me in 1998 and told me he had bought some Studi/o PCI cards and really liked them.  So he hired me to do a modified version as the audio engine in the...

 

I did this at Ariel in 1992.  We came to call it the Don Module because at the time, we were also working with TI DSP's and TI had defined a module spec called the TIM Module.  Well, we had a pair of engineer...

 

I designed this for TC Works in 2000.  I designed the system architecture and then refined it with Klaus Bahner of TC.  Then I designed the hardware while Klaus designed the software system to load plugins, d...

 

After leaving Sonorus the guys from Event tapped me to do an ADAT companion to their EZ-Bus board.  What am I the ADAT optical interface king or something? ha!  But it was a fun project, great guys to work with...

 

While working at Ariel, my good friend Tom Hegg was an engineer over at Avid.  We ended up collaborating on a NuBus board which Avid used for a couple of years in the Media Composer system.  It was the world's ...

 

I developed the RT-60 analysis software package for the RTA-1 while at dbx, improved the confidence estimation using cluster analysis techniques, as well as support the entire software package.  The unit was widely ...

 

Pluzilla was the world's first hardware plugin player.  Joe Waltz developed the idea, and I put together the Manifold labs team to productize it.  I did a couple of USB drivers for some joysticks, debugged the ...

 

This desktop logger was the first of the new line of linux-based loggers for Eventide.  I wrote the application code, working closely with Don Elwell who did the hardware and most of the drivers.  I used wxwidg...

 

Fixed some nasty bugs in the PIC processor code in the motion sensors for this system, resulting in something like a 4x improvement in RF range.  Also extended the wireless data format to add a packet counter to all...
