Our department labs are designed to give students hands-on opportunities to keep up with ever changing times and technology. These experiences in addition to class-room instruction are an excellent recipe for success in the real world. We offer the following labs:
Basic Lab, VET 176
The basic lab serves students who are enrolled in ET 3601, Electrical Circuit Analysis I (DC), and ET 3602, Electrical Circuit Analysis II (AC).
The lab is equipped with 12 stations, each accommodates 2 students. Two additional stations were added recently (Jan. 2006) in order to accommodate up to 28 students. Each station is equipped with the followings (the two new stations are being equipped):
1. Internet-connected PC, (recently replaced Aug 2005) loaded with:
2. Triple outputs Tektronix power supply.
3. Four digital multimeters (4.5 and 3.5 digits), two of which were purchased recently.
4. 2-MHz Sweep function generator.
5. 40 MHz two-channel analog oscilloscope.
6. Breadboards, potentiometers, jumper wires, etc.
The basic lab has also a small collection of reference materials and manuals.
Power Lab and LAN Lab
Two years ago, there was a major reorganization and renovation on the laboratories in the ET area. The new power lab has more space (a total of 1100 plus ft 2) and better looking now. This lab serves as the lab facility for ET4600 (Programmable Logic Controllers), ET 4610 (Instrumentation and Controls), ET 4640 (Industrial Electricity), and ET4802 (Senior Problem in Engineering Technology). In the last six years, many pieces of new equipment and software have been purchased for the power lab. These include:
This laboratory serves ET-4860 and many student and faculty projects
The Robotics laboratory houses:
1 Mitsubishi RV-M1 industrial robot with controller
1 electric two-finger gripper with variable pressure control
1 1200-mm robot linear track with controller
1 signal interface and multiplexer
1 teach pendant with emergency button
1 PC loaded with Roboware with I/O capabilities
In addition to the robotic system described above, the ET program has recently purchased;
15 Handyboard circuits - based on M68HC11 microprocessor
15 robotics LEGO set to be used for mobile applications
Various light, sound, and touch sensors to be used in mobile applications
15 Robotics textbooks - Robotics Explorations by Fred Martin - provided to students
The Handyboard-based robotics activities use Interactive C language for programming. Almost half of the current robotics course (ET-4860) utilizes the Handyboard circuit, which in turn require many session of computer programming.
This laboratory serves ET-4850 and many student and faculty projects

Automation Studio ver. 5.3 (six seats) are installed in VET 118. We have secured funding for additional copies
PNEUMATIC TRAINING SYSTEM (purchased in 2003-2004)
All components are FESTO first line, industrial grade quality and ISO compatible. Quick disconnects provide fast assembly and disassembly of circuits without the use of hand tools. The components operate on normal shop air (90psi). The plastic tubing used for circuit hook
up use kink-resistant PUN_4 x 0.75 polyurethane, 4mm ID tubing. The air manifold is check valve protected with an emergency dump valve built in. The Basic Pneumatic component set contains the following items:
2 152865 Pressure gauge, 0 _ 10 bar, 40 mm diameter dial
3 152873 5/2_way pneumatic valve, pneumatically actuated on both sides
1 152875 Shuttle valve (OR), with two inputs for the "OR" logic function
1 152876 Dual_pressure valve (AND), with two inputs for the "AND" logic function
1 152879 Time delay valve, pneumatically actuated, adjustable 0 ... 5 sec., normally closed
1 152894 On/off valve with filter regulator, for unlubricated compressed air supply, the main line can be switched on or off, the system is vented when switched off
1 152895 Pressure regulator with pressure gauge, control range 0 ... 12 bar, range of indication 0 ... 16
1 152896 Manifold, 8 connections with self_closing plug_in coupling
1 152898 Connection components kit, 8 pieces, quick push_pull connectors
ADVANCED PNEUMATIC PORTION
The advanced pneumatic portion is designed and manufactured to provide continued study from the basic pneumatic curriculum.
Hardware set contains the following:
2 152882 Shuttle valve (OR), with 3 separate "OR" elements
1 152883 Dual Pressure valve (AND), with 3 separate "AND" elements
1 152898 Connection components kit, 8 pieces, quick push_pull connectors
1 120763 Equipment Tray
The Electro_Pneumatic portion is designed as an add-on component/software package to teach modern electro_pneumatic control technology. All components are compatible and interchangeable with the basic/advanced pneumatics training packages.
ADVANCED ELECTRO_PNEUMATIC PORTION
The Advanced Electro_Pneumatic portion is designed as a component add-on package to teach a higher level of electro_pneumatic control technology. The Advanced Electro_pneumatics training package contains the following items:
Automation Studio ver. 5.3 (six seats) are installed in VIS 118. We have secured funding for additional copies
Engineering Technology (ET) CADD Facility
In Spring 2001 we moved to room MGB 201, our new Computer-Assisted Drafting and Design (CADD) lab in the Midgett Building. Thanks to the technology access fee and other sources of funding, now we have a renovated and well-equipped CADD lab. This lab has several features including thirty six Pentium 2.8 and 3.2 GHz student workstations and five printers. Internet access is provided to all computers and printers, enabling students to send files directly to the printers. The three inkjet printers and one LaserJet printer can produce letter (A) and tabloid (B) size color prints/plots. The large DesignJet printer can produce A-E size color plots/posters.
The CADD lab is also a master classroom that will allow us to teach other courses and use Web-enhanced instruction. The multimedia workstation and the overhead LCD color projector help us teach CADD interactively and effectively. We have one workstation on a cart for the use of instructors and students to install and test new software. We teach ET 2310 - CADD I (two-dimensional CADD), ET 3360 - CADD II (3D or solid modeling) and ET 4330 - Advanced CAD. We have an annually renewable site license from AutoDesk Design Institute (ADI) to install several CADD software including AutoCAD, Inventor, Revit, Electrical and Mechanical Building Systems, and AutoCAD - Electrical. We receive software upgrades from ADI as and when they become available. Recently, we received a grant to install the 3D modeling software, SolidWorks in the CADD lab computers and several other workstations in the ETIS department. Additionally, MS Office has been installed in all computers. We teach AutoCAD in ET 2310 and Inventor in ET 3360. ET 4330 is mainly a project-based course in which students use Inventor, SolidWorks and Revit to work on their projects.
