Freshman Projects Laboratory – Bogard Hall Room 129
All freshman engineering students complete ENGR 120, 121 and 122 in the classroom / laboratory / shop facility shown in Figure 1. The laboratory is designed to support 40 students (working in teams of 2 to 4) and is equipped with 11 tables for project work, note taking, and group interaction.

The walls of the laboratory are lined with 86 linear feet of cabinets with stainless steel counter tops. These cabinets provide the work surface required for project fabrication and the storage space needed for supplies and equipment. Ten identical work stations are distributed around the room to allow all 40 students in the class to work simultaneously. A work station is shown in Figure 2.

A Wabeco D600E lathe with a FAGOR 2-axis digital readout, Swiss-style quick change tool set, and a turret tailstock is available for fabricating conductivity sensors in ENGR 121. The laboratory also houses a Dayton 18” variable speed band saw and a Wilton vertical belt sander/chamfering tool for general project work in ENGR 122.
temperature detector (RTD) is fabricated in ENGR 121 using photolithography,
requiring the following equipment:
Figure 3 shows some of the equipment and an RTD fabricated in the laboratory.

Students taking ENGR 122, which focuses on innovative product design, can “borrow” a host of sensors and other parts needed to facilitate their projects, including servos, RF transmitters/receivers, temperature sensors, humidity sensors, GPS receivers, digital compasses, 2- and 3-axis accelerometers, ultrasonic sensors, force sensors, touch sensors, and cameras (about $10K worth of various sensors). These sensors can readily be interfaced with the student-owned Boe-Bot kits that serve as the backbone of the freshman laboratory experience.
Pump Testing Stations: Our laboratory is equipped with five portable stations that allow students to determine the efficiency of their pumps in ENGR 120. The design of these stations is provided here.
