Generating Fibonacci Series with LabVIEW

Fibonacci series can be generated with LabVIEW using a For Loop, Shift Registers and an Addition Operator. In the example below, we provide a Front Panel Control with the number of Fibonacci series entries to generate. We initialize two shift registers, and pass the current Fibonacci sum as well as the previous Fibonacci entry to […]

Using MCP3008 ADC with Raspberry Pi

Raspberry Pi does not have a built-in ADC. Which means an external ADC has to be used to capture analog signals. In theory, it is possible to capture certain analog signals via the audio input jack, but there may be limitations on the signal amplitude and frequency ranges, among other issues. MCP3008 is an 8 […]

Continuously updating audio waveform display using Python

While matplotlib works well for displaying static graphs and charts, sometimes we may need to display a continuous (live) waveform on a graph. This requires repeatedly retrieving and displaying samples of incoming data (an audio stream, for example). An interesting way to display such a continuously varying waveform is to use the ‘Animation’ classes built […]


What will become of you and me Besides the photo and the memory? This is the school in which we learn. That time is the fire in which we burn. What is the self amidst this blaze? What am I now that I was then, which I shall suffer and act again? The children shouting […]


Slowly the golden memory of the dead sun fades from the hearts of the cold, sad clouds. Silent, like sorrowing children, the birds have ceased their song, and only the moorhen’s plaintive cry and the harsh croak of the corncrake stirs the awed hush around the couch of waters, where the dying day breathes out […]


I always enjoy observing people at the airport. Some look stressed and move quickly, others have a blank look on their face. Businessmen pacing around while talking on their phone, oblivious of the world around them. A group of friends returning from a trip. People drinking beer at 8 am, because the usual rules don’t […]
