Web interface for audio processing appliance

25-Seven Systems has created an audio processing appliance called Audio Time Manager. I designed and implemented a new web interface for the Linux-based ATM, replicating the physical front panel in great detail. Using a Flash-based web applet, communicating with a custom C++-based server within the ATM, the web interface gives low-latency control to remotely-located audio engineers. I also consulted extensively on and created the web interface for their new product, the Program Delay Manager.

You can see the ATM and PDM web interfaces at <> and <>.

The BarrettHand

This is a microcontroller-based three-fingered robotic hand with four degrees of freedom. It is controlled by a 68HC11 microcontroller with program storage in EEPROM. The hand implements a command set that allows complete freedom in setting finger positions, velocities, and pressures. Normally, the hand will be mounted on a robotic arm, with a workstation controlling both the hand and the arm.

I designed the hand control language and wrote the microcontroller software in C. I also consulted on a variety of issues, ranging from power supplies to driver electronics to testing strategies. I also recently upgraded the hand software to allow high-speed realtime control of the hand.

Nine products for Museum Technology Source

Over the course of three years I wrote the software for nine microcontroller-based products for Museum Technology Source. These were stand-alone videodisc and compact disc controllers, with one to twelve buttons for visitors to select different programs.

Each controller was designed to be easily configurable by the customer. The videodisc controllers had the capability of being programmed without any additional equipment, just by using the character generator built into every Pioneer videodisc player. The controllers displayed multiple-choice menus on the video screen; the customer then used the controller's front panel buttons to make choices.
