Faint memories of some old projects.
Propeller Clock
This is a replica of Professor Bob Blick's Propeller clock.Based on the PIC16F84, one of my first and favorite project.Link to the real clock is here
IRDA Transceiver
An Irda Transceiver designed to work with motherboards that have an on board IR port.posted online at Technick.net
Infrared Transceiver
An Infrared Transceiver designed to run on RS232 ports.
Mono Sub Amp
One of the biggest projets i've ever done, a Mono Car Amplifier for a Sub. with a ±30V push pull Mosfet powersupply. the cooling fans were a bit of an overkill.
Pedometer
A Pedometer that runs on a single 1.5v cell.note the piezo electric transducer that when tapped increments the steps. based on a PIC16F628 with an onboard osscilator.
Winamp LCD
LCD connected to the parallel port to display the information of song playing in winamp. nothing special but the best way to test a 16x2 LCD in pre microcontroller era.
Pro PIC II
A Propic II programmer that can program the entire PIC series. note the absence of a ZIF socket that was very expensive in India at that time. neat!
Atmel Programmer
A Quick and messy Atmel programmer made to test the worthiness of Atmel 89C2051/4051 against the PIC micros. PIC micros won of course.
Custom Mouse Lights
aim was to fit a microcontroller in a mouse to control 16 cellphone leds. the leds run in a sequence in accordance to the serial data a mouse sends. leds respond to the motion of the optical mouse. even the slightest movement triggers it. only two were made!
Twin Strobe Controller
Taking inspiration from police cars this is a sequence controller to trigger 2 independent strobe lights. four buttons - two for sequence up/down - two for speed change. This sure was a head turner for my car.even police cars were at shame.The smallest micro around, the PIC16F629.
