A photovoltaics teaching aid. The present device is adapted to serve as a teaching aid in order to assist individuals in learning the principles behind photovoltaics, in order to better promote science, technology, engineering, and mathematics (STEM) education. The present invention is a transportable cart including an angled, adjustable array of solar panels, a rechargeable battery, and a solar water heating system. The present invention further includes a number of different devices that are removably attached to the cart to assist individuals in making necessary measurements for calculations, including a multimeter and an angle gauge. Furthermore, a bus is provided that allows individuals to alternatively connect the panels of the solar array in series or in parallel. By changing the manner by which the panels are connected, individuals can study the different resulting effects on the other electrical components.

An electronic circuit construction system uses plastic perforated connectors with mounting posts that are inserted directly onto a pictorial diagram of an electronic circuit. An underlying foam base anchors the posts in place. Components and hook-up wire depicted on the diagram are then installed in place on the connectors to complete the electrical circuit.

A breadboard comprising a plate made of an insulating material and having a connection strip portion including a grouping of at least three rows of sets of at least three spaced apart holes in each set in the plate, the centers of the holes in each set being spaced from each other by a predetermined distance defined as a space, groups of at least three connector clips in the plate each connected in at least a three gang grouping, each referred to as a conductive strip which is aligned with and beneath one of the rows of sets of pinholes with all conductive strips being electrically isolated from each other, and all the in each row being offset from the conductive strip in an adjacent row by the predetermined distance and the sets being aligned in each row, end-to-end, with one space between end holes of two adjacent sets in a row, and each row being offset or staggered from each adjacent row by at least one space such that an array of spaces is formed, with each interior space in the middle row forming a center of a diamond shaped four pin socket, that has a connector clip in the plate at each of its four points or corners, that originates from a different conductive strip and that may be used for receipt of a three or four pin component.

The invention discloses a microcontroller comprising a first and a second processor ICs. The first processor IC is configured to store data representing sound signals and to perform decompression process for retrieving said sound signals. The second processor IC is configured to provide I/O pins for interfacing with external application circuits. An integrated programming technology is developed to program both processor ICs at the same time.

The invention provides for a shell having four sides including a front side and a front side having contact points to simulate a host component where the number of contact points and spacing between the contact points on the front side of the shell simulate the number and spacing of receptacles located on the host component so that the shell may be temporarily populated with accessories and the accessories capable of being serially removed and serially attached to the receptacles of the host component. The shell may be carried in a shipment container along with the accessories for shipping to the location of the host component. The accessories may include cable harnesses and have fiber optic connectors temporarily mounted to the component simulation shell during shipping and upon arrival at the host component, the connectors may be removed in a one-to-one matching sequence between the component simulation shell and the host component where the connectors are finally mated.

The object of the present invention is to assign line break numbers to locations where line breaks have been made in order to separate a series of figures configured by connecting a number of figures into parts in a manner which makes it easy for a user to view a drawing including the series of figures, or a series of figures. In response to a line break operation for separating a series of figures configured by connecting a plurality of figures into parts, line break numbers displayed at line break locations are sorted based on a positional relationship of the line break locations. The series of figures with the sorted line break numbers assigned to the line break locations is displayed after performing the line break operation. The line numbers are therefore assigned in a consecutive manner for each series of figures. If there are a plurality of series of figures within a drawing, the line break numbers are assigned to the series of figures using a predetermined rule so that the drawing as a whole becomes easier to see.
