AK-110 Audio Visualizer LED Ripple D.I.Y. Kit
This fun Audio Visualizer utilizes a CD4017 logic IC to produce audio visualization based on the input through the microphone. Once the unit is assembled, use an external 3-5VDC power supply or insert two AA batteries into the battery holder and power on. It comes with a seven page colored manual illustrating step by step instructions.
Teachers love this kit. Students will enhance their soldering skills on a high quality PCB, and end up with something fun.
The boards that come with this kit are not only good-looking, with gold plated pads, black solder mask and a white silk screen, but also very functional. Gold plated pads require less heat and allow solder to flow easily. Also due to it being a double-sided PCB, both top and bottom holes are plated in order to provide a better connection.
Remarks: This kit comes with a basic Electret Condenser MIC which has low sensitivity for lower sound frequencies. For better performance, input higher frequency sound (i.e. high bass sound and not human voice) or place the source audio output very close to the MIC.
