oscillator circuit is composed of an to be different from those of the two oscillators [8].inductor, a capacitor and some form of resistor wiredin a loop in series (an LRC circuit). By Kirchhoff’slaws, the sum of the voltages across each componentmust be zero. This gives the following equation: q dI IR + +L =0 (1) Figure 1: Two mass-spring mechanical oscillators C dt coupled with a coupling spring. Where q is the capacitor charge, and I = dqdt is Let x1 and x2 be the position of both massesthe current. This can be converted to the following

measurements.Project assessment is based on mathematical rigor, ingenuity and aesthetics in engineering design, andmeasurements and analysis. The project takes an average of 2-3 weeks to finish. Students are encouragedto additionally rock the roly-poly to perform simple harmonic motion and to measure the oscillation frequencyand amplitude, which is a preamble to subsequent courses in dynamics, engineering design, controls andmechatronics. Figure 3. Typical results of theoretical curves: solid curves refer to F() for specific  and U() for specific values of F, while the dashed curves are locus connecting the minimum of U(q). Experimental data are shown as symbols. Tilting angles are measured using a homemade device

. Figure 3. Custom-fabricated ECG lead wires clip to tab-style electrodes.For the ECG lab, students apply skin surface electrodes (such as Covidien Kendall Q-Trace tabelectrodes or NikoTab #0315 electrodes) and connect them to their amplifier circuit via customfabricated ECG leads (Fig. 3). Leads are fabricated from three 1-m lengths of 26 gauge stranded,silicone-insulated wire in three colors (black – negative; red – positive; green/blue – ground).One end of each wire is crimped to a mini alligator clip (source) and the other to DuPont-stylepins for stable connection to the breadboard. These leads perform better than alternatives, beingmore flexible than solid wire (that can insert directly into a breadboard but tend to pull offelectrodes) and
