A science kit to assist with hands-on education of electronics and foundation science.

Purpose

The idea is to have a collection of sensors and input devices that can be connected to the XO and also to work independently of the XO in circuits constructed by students. I would like to create a standard connector for all peripherals which enable the easy construction of circuits. Possibly USB connectors could be used which would enable rapid circuit construction and modification while also remaining a convenient interface method for connection to the XO.

Possible components

  • Cables
  • Switches
  • Motors / Generator
  • Solar cells
  • Lights (LED)
  • Buzzer
  • Digital Control Unit
  • Mini USB battery, so it can be used to power a simple circuit
  • Light sensor
  • Temperature
  • Pressure
  • Hall effect
  • Current
  • Voltage
  • Current/voltage probe
  • Charge
  • Accelerometer
  • Distance
  • pH
  • Salinity
  • Radiation
  • Prism

hardware needed

a fuse protected serial or parallel port for continuity testing. and multiple voltage detectors. All other sensors report back to the computer in on off or analog. AaronPeterson 17:55, 23 December 2007 (EST)

TI graphing calculators have had these components as accessories for a long time and cost less than 100 dollars. http://www.ticalc.org/ and http://education.ti.com product exapmle: http://education.ti.com/educationportal/sites/US/productDetail/us_easydata_easytemp.html AaronPeterson 17:55, 23 December 2007 (EST)

Motivation

  • Hands-on activities are essential for a rounded education

Advantages

  • A highly adaptive and rapidly interchangeable collection of sensors and components would enable construction of potentially useful devices.

Disadvantages
