Filtering Noisy Arduino Measurements
Paul Martinsen @ megunolink.com discuss about noise in analog input of arduino and how to filter it. He examines 3 filtering algorithms: Averaging, Running average, Exponential filter and provides the code to achieve that. Measurements from the real world often contain noise. Loosely...

Reverse Engineering a Simple Four Function Calculator: die decap
Electronupdate did a teardown and analysis of a cheap four function calculator: It’s such an amazingly old looking die. Even with 400x magnification it would not be too hard to reverse engineer back to a schematic! This must be a very old design indeed. When one thinks of...
