Not bad for $44 – lots of project to make with this – “We have found many different uses for this little kit! Applications ranging from the traditional ECG/EKG monitor to the ‘Newly-Wed’ Love Synchronizer! One of the main reasons we designed the ECG1 was to answer a long running debate here at the shop. We wired up the ‘Boss’ and finally confirmed he does not have a heart! Use the ECG1 to astound your physician with your knowledge of ECG/EKG systems. Enjoy learning about the inner workings of the heart while at the same time covering the stage-by-stage electronic circuit theory used in the kit to monitor it.” Link.
