  • CHI - AutoFritz: Autocomplete for Prototyping Virtual Breadboard Circuits
    Proceedings of the 2019 CHI Conference on Human Factors in Computing Systems - CHI '19, 2019
    Co-Authors: Jo-yu Lo, Da-yuan Huang, Teddy Seyed, Xing-dong Yang, Jun Gong, Bing-yu Chen
    Abstract:

    We propose autocomplete for the design and development of virtual Breadboard circuits using software prototyping tools. With our system, a user inserts a component into the virtual Breadboard, and it automatically provides a user with a list of suggested components. These suggestions complete or ex- tend the electronic functionality of the inserted component to save the user's time and reduce circuit error. To demon- strate the effectiveness of autocomplete, we implemented our system on Fritzing, a popular open source Breadboard circuit prototyping software, used by novice makers. Our autocomplete suggestions were implemented based upon schematics from datasheets for standard components, as well as how components are used together from over 4000 circuit projects from the Fritzing community. We report the results of a controlled study with 16 participants, evaluating the effectiveness of autocomplete in the creation of virtual Breadboard circuits, and conclude by sharing insights and directions for future research.

  • gaussstarter prototyping analog hall sensor grids with Breadboards
    User Interface Software and Technology, 2015
    Co-Authors: Ronghao Liang, Bing-yu Chen
    Abstract:

    This work presents GaussStarter, a pluggable and tileable analog Hall-sensor grid module for easy and scalable bread- board prototyping. In terms of ease-of-use, the graspable units allow users to easily plug them on or remove them from a Breadboard. In terms of scalability, tiling the units on the Breadboard can easily expand the sensing area. A software development kit is also provided for designing applications based on this hardware module.

  • carbon nanotube pattern formation precise routing on silicon oxide using nanoscale catalyst Breadboards
    IEEE Transactions on Nanotechnology, 2012
    Co-Authors: Chris Papadopoulos
    Abstract:

    A method for directly routing single-walled carbon nanotubes on silicon dioxide is presented. The lack of a preferred direction on the amorphous oxide film was overcome by placing nanoscale catalyst particles on the surface in the form of a grid or Breadboard. Colloidal lithography was used to create an ordered nanoscale array of uniformly distributed Fe/Mo catalyst particles to serve as the Breadboard. Following chemical vapor deposition at 900 °C with a methane/hydrogen gas mixture, intricate nanotube patterns that corresponded to the underlying Breadboard were formed. Most patterns were found to consist of individual tubes or few-tube bundles. A “lift-and-drop” model was used to describe the nanotube pattern formation process whereby a combination of gas flow and van der Waals interactions allows tube growth to be precisely guided onto the Breadboards without requiring an external impetus. These results indicate a potential path to carbon nanotube integration on standard oxide films for future deep nanoscale electronics.

  • Gene circuit performance characterization and resource usage in a cell-free "Breadboard"
    ACS Synthetic Biology, 2014
    Co-Authors: Dan Siegal-gaskins, Zoltan A. Tuza, Vincent Noireaux, Richard M Murray
    Abstract:

    The many successes of synthetic biology have come in a manner largely different from those in other engineering disciplines; in particular, without well-characterized and simplified prototyping environments to play a role analogous to wind-tunnels in aerodynamics and Breadboards in electrical engineering. However, as the complexity of synthetic circuits increases, the benefits—in cost savings and design cycle time—of a more traditional engineering approach can be significant. We have recently developed an in vitro “Breadboard” prototyping platform based on E. coli cell extract that allows biocircuits to operate in an environment considerably simpler than, but functionally similar to, in vivo. The simplicity of this system makes it a promising tool for rapid biocircuit design and testing, as well as for probing fundamental aspects of gene circuit operation normally masked by cellular complexity. In this work, we characterize the cell-free Breadboard using real-time and simultaneous measurements of transcri...

    Abstract:

However, as the complexity of synthetic circuits increases, the benefits--in cost savings and design cycle time--of a more traditional engineering approach can be significant. We have recently developed an in vitro ‘Breadboard’ prototyping platform based on E. coli cell extract that allows biocircuits to operate in an environment considerably simpler than but functionally similar to in vivo. The simplicity of the cell-free transcription-translation Breadboard makes it a promising tool for rapid biocircuit design and testing, as well as for probing the fundamentals of gene circuit functions that are normally masked by cellular complexity. In this work we characterize the cell-free Breadboard using real-time and simultaneous measurements of transcriptional and translational activities of a small set of reporter genes and a transcriptional activation cascade. We determine the effects of promoter strength, gene, and nucleoside triphosphate concentrations on biocircuit properties, and we isolate contributions of the essential components--core RNA polymerase, housekeeping sigma factor, and ribosomes--to overall performance. Importantly, we show how limits on essential resources, particularly those involved in translation steps, are manifested as reduced expression in the presence of orthogonal genes that serve as additional loads on the system.

  • demonstration prototype and Breadboards of the piezo stack m4 adaptive unit of the e elt
    Proceedings of SPIE, 2010
    Co-Authors: B. Crépy, S Chaillot, Maíra Cola, Jean-marc Conan, Raphael Cousty, M Dimmler, J L Dournaux, S De Zotti, Eric Gabriel, Rami Gasmi
    Abstract:

    In order to mitigate the risks of development of the M4 adaptive mirror for the E-ELT, CILAS has proposed to build a demonstration prototype and Breadboards dedicated to this project. The objectives of the demonstration prototype concern the manufacturing issues such as mass assembly, integration, control and polishing but also the check the global dynamical and thermal behaviour of the mirror. The local behaviour of the mirror (polishing quality, influence function, print through...) is studied through a Breadboard that can be considered as a piece of the final mirror. We propose in this paper to present our Breadboard strategy, to define and present our mock-up and to comment the main results and lessons learned.

  • The DARWIN Breadboard cryogenic optical delay line
    International Conference on Space Optics — ICSO 2006, 2017
    Co-Authors: Teun C Van Den Dool, F.g. Kamphues, W.l.m. Gielesen, N. Loix, P. P. Kooijman, C. P. De Vries, H. Van Weers, K. Fleury, Yvan Stockman, G. Velsink
    Abstract:

    TNO, in cooperation with Micromega-Dynamics, SRON, Dutch Space and CSL, has designed a compact Breadboard cryogenic delay line (figure 1) for use in future space interferometry missions. The work is performed under ESA contract 17.747/03 in preparation for the DARWIN mission. The Breadboard (BB) delay line is representative of a flight mechanism. The delay line has a single stage voice coil actuator for Optical Path Difference (OPD) control, driving a two mirror cat’s eye. Magnetic bearings provide frictionless and wear free operation with zero-hysteresis. The design of the BB delay line has been completed. The development test program, including operation at 100 K has been completed. The verification test programme is currently being carried out and will include functional testing at 40 K.
