Derived from Microchip’s AN1115 application note, this experiment implemented a locked-in amplifier circuit and C firmware running on a microcontroller to measure a resistance.

Initially implemented by Microchip using a dsPIC, I ported the logic to a PIC32 running on an Explorer 16 Development ...

I print pictures on my color laser printer (Canon LBP612CDW). When I needed to print a passport photo I found that the skin tones were off; there was a strong red shift in the skin.

In order to create better prints I calibrated my printer profile with the aid of a flat-bed scanner.
