Peripherals/Science Kit

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
