Circuit Design

If you need a custom circuit, we can design one for you.

Don't waste time trying to do it yourself. Let our professional staff empower your research or instruction with custom circuitry. We may already have the design you need. Get your specifications together and come by 64 Burrill Hall.

We provide complete documentation: schematics, layout, operation, parts lists.

Previous designs include:

  • electroporators- our famous "Gene Zapper"
  • computer interfacing
  • insect counters
    • flying insects and their biomass
    • bees entering hive/ bees exiting hive
  • turtle compasses
    • opto-electronics sensors
    • 8 points of the compass
    • sleep/swim indicator
    • interfaced to computer
  • dishwasher controller
    • replaced obsolete factory controller
    • uses programmable logic controller
    • controller can be reprogrammed and used elsewhere
    • extremely hardy
  • low-level analog amplifiers
  • low voltage DC power supplies
  • high voltage switching DC power supplies
  • circuit to synchronize a strobe lamp, video camera, and VCR
    • provides marker every 10 frames on VCR tape
    • gives different marker every 100 frames
    • triggers strobe lamp
    • freezes motion of subject
  • light sensors
  • motor controllers
  • voltage clamps
  • opto-electrical position sensors

Circuit/Chassis Construction

Do you have:

  • electronic circuits you need to have built

  • gain
  • resolution (A/D bits)
  • sampling rate
  • data logger/serial or parallel box/PC expansion card
  • PC bus type
  • data acquisition software
  • data analysis software

If you need a system designed and set up, need recommendations on a board or software, or if you just have a question, see Gerald Frank.

There are also catalogs for:

  • National Instruments
  • Keithley Metrabyte
  • Intelligent Instrumentation
  • Industrial Computer Source
  • CyberResearch
  • Datel
  • ComputerBoards
