I've been dabbling with creating my own circuit boards for a while now. I recently used KiCad to design this audio DAC circuit board. I had the board manufactured by OSHPark and assembled it myself using a solder paste stencil and my DIY solder reflow oven.

The board plays audio using a typical 3…

Wanting to learn more about creating embedded Bluetooth Low Energy (BLE) firmware, I recently purchased a Nordic nRF52840 dev kit shown below.

I also purchased an inexpensive BLE heart rate monitor and a small OLED display from Adafruit to use with the nRF52840 to display realtime data from the hea…

I’ve been working with ARM Cortex-M4 microprocessors for a little over a year and a half now. Despite reading popular embedded books and blogs, I have yet to come across an end-to-end overview of the creation and execution of a program.

For my own education and reference I’ve created such a docume…

I've been working on an audio analysis tool, lately. Here's a screenshot:

One of my interests involves creating software algorithms that manipulate audio in various ways. This frequently involves analyzing various numerical data.

Tired with writing specialized scripts corralling specific data and…
