Automatic monitor brightness controller

Monday, April 4th, 2016

Dilshan Jayakody writes: This is an automatic "monitor brightness controller" based on environmental light conditions. This system use USB port base sensor unit to measure the light level and control monitor brightness accordingly. We design this system to reduce the eye stress by matching the monitor brightness with environmental lighting....

Part tester and Superprobe rolled into one

Monday, September 10th, 2012

Dolabra is designing Donatello, a Part Ninja and Superprobe combo. Instead of having a display on the board, like the Superprobe and Part Ninja, he delegated the display to a host computer over USB. My intention is to make a combination part ninja and super probe. The idea is a...

HID is one step closer on the open source USB stack for PIC microcontrollers

Tuesday, March 6th, 2012

Dolabra took up the task to add support for the HID class to Hoken and JTR's open source USB stack. Up till now it only supported the CDC class, and HID is still a long way away, but progress has been made. Yeah! a small victory. I got a set...

App note: Digital HID Ballast Reference Design

Sunday, November 6th, 2011

High intensity discharge ballasts, used in cars today, require a large set of analog controllers to ignite an HID bulb and reach steady-state operation. This reference design from Microchip describes how to make an HID ballast using a dsPIC and a few discrete components. The reference design uses 9-16VDC and...

Parallax Optical Finger Navigation module

Wednesday, December 22nd, 2010

Parallax has introduced their Optical Finger Navigation (OFN) sensor module. This HID is designed to sense the presence of a finger and track its movement much like a mouse. Interfacing is via I2C, supply voltage between 3.3 and 5.5 volts, and convenient 0.1" pin spacing for breadboarding. A detailed review...

USB Performance Monitor

Sunday, April 25th, 2010

We like the professional look of this USB PIC (18F2550) project from WaitingForFriday. Analog VU meters and an RGB LED show system stats like CPU use, network speed, and hard disk activity. The PIC enumerates as a driver-less USB HID device with a firmware based on the Microchip USB stack....
