The Velleman Educational LCD Oscilloscope Soldering Kit allows you to learn how to visualize signals by building a DIY oscilloscope.
You can see live signals. Despite its low cost, it offers many features found only on more expensive units, including signal, frequency, sound intensity (dB), and root mean square (RMS) readings. An auto setup feature helps you get started quickly.
Note: This oscilloscope cannot measure voltages greater than 30Vpp.
