Oversubscribing Inotify On Embedded Platforms, Donald Percivalle, Scott Vanderlind

Computer Engineering

For most computers running the popular Linux operating system, the inte- grated kernel component inotify provides adequate functionality for monitor- ing changes to files present on the filesystem. However, for certain embedded platforms where resources are very limited and filesystems are very populated (like network attached storage (NAS) devices), inotify may not have enough resources to provide watchers for every file. This results in applications missing change notifications for files they have watched. This paper explores methods for using inotify most effectively on embedded systems by leveraging more la- tent storage. Benefits of this include a reduction in dropped notifications …

Programmable Coffee Roaster, Steven Jack

Computer Engineering

The rise of the third wave coffee movement has led to the desire for fine-tuned control over the quality of roasted coffee. This project explores modifying a toaster oven into a personal home coffee roaster for hobbyist use.

M-1: The Mealy Open Source Custom Midi Controller, Garrett Leung, Darren O. Mistica

Electrical Engineering

With the high price of large mixing consoles, aspiring artists are restricted to using a mouse to control digital facsimiles of knobs, faders, switches, and buttons. Though using the software controls is considered a simple task, dedicated hardware allows for tactile, visual, and utility. At a low cost, the heart of the MTech M-1 can be customized and placed into any shell with any combination of controls as possible with the underlying platform.

Modern MIDI controllers require significant physical space due to their preset button layout and space consuming setups. Despite their high price, modern MIDI controllers have only one …
