Abstract
A toy construction set may utilize blocks with electrical connections, this block receives electrical power, outputs energy in the electromagnetic spectrum, receives reflected energy and outputs a result to be utilized elsewhere in the toy assembly. Though it has connectors to attach it to other like blocks, it has a bearing shaft to enable an anemometer (FIG. 5) or a tachometer. It may sense bar codes and enable an assembled vehicle to accept trackway commands.
