Electrick is a low-cost and versatile sensing technique that enables touch input on a wide variety of objects and surfaces, whether small or large, flat or irregular. This is achieved by using electric field tomography in concert with an electrically conductive material, which can be easily and cheaply added to objects and surfaces. We show that our technique is compatible with commonplace manufacturing methods, such as spray/brush coating, vacuum forming, and casting/molding, enabling a wide range of possible uses and outputs. Our technique can also bring touch interactivity to rapidly fabricated objects, including those that are laser cut or 3D printed. Through a series of studies and illustrative example uses, we show that Electrick can enable new interactive opportunities on a diverse set of objects and surfaces that were previously static.

EEPFS filesytem EEPROM
EEPFS is a very simple filesytem EEPROMs, non volatile RAM and so on. It is not suitable for flash, either NOR or NAND because it relies on being able to do writes with arbitrary data at a byte granularity.

Real Time Programming
Real-time computing is a key feature of many robotics systems, particularly safety- and mission-critical applications such as autonomous vehicles, spacecrafts, and industrial manufacturing. We are designing and prototyping ROS 2 with real-time performance constraints in mind, since this is a requirement that was not considered in the early stages of ROS 1 and it is now intractable to refactor ROS 1 to be real-time friendly.

lowRISC · lowRISC
lowRISC is creating a fully open-sourced, Linux-capable, RISC-V-based SoC, that can be used either directly or as the basis for a custom design. We aim to complete our SoC design this year.

Our open-source SoC (System-on-a-Chip) designs will be based on the 64-bit RISC-V instruction set architecture. Volume silicon manufacture is planned as is a low-cost development board.

lowRISC is a not-for-profit organisation working closely with the University of Cambridge and the open-source community.

DoorScope, the free DOORS and ReqIF viewer
DoorScope is a software application which can be used in the specification review process. Specifications can be exported from IBM DOORS® and viewed with links, object attributes and change history (including tables, images and richtext). Objects can be annotated and marked with their review status. There is also a fulltext search and scripting facility. DoorScope is a single executable and runs natively on Windows without installation. The source code is available under GPL or - on request - under user-specific licences.
