Measuring Heart Rate
21. June 2008 - 8:34 — adminDid you know that The human heart can be measured optically. The heart beat with the varying blood pressure leads to a measurable change in the visual content of peripheral blood vessels. This is as good at the finger detect. There are two project work available, which were so far advanced that the optical signal pulse seized on a liquid crystal display graphically. Both works have been with a microcontroller PIC16C74 to collect and visualization of the signals.

Flickr images on a Nokia 6110 Color LCD
14. June 2008 - 14:01 — adminMost used are these green character displays with two or more rows to display menus, status or debug messages. With mass production of mobile phones, color LCDs get that cheap, that they can be used as replacement. To test the display, I hacked a kind of small digital picture frame, that fetches pictures from Flickr.
Custom characters on HD44780-based LCD display
8. June 2008 - 12:47 — adminThis article discusses how to overwrite bytes in the CGRAM to display custom bit-map graphics on a Hitachi HD44780-compatible character LCD display. A method is described of transforming a raster image to an array of values that are a monochrome bit-map representation of the original.
