I had designed a remote unit for my ST4000+ autopilot. It did prove out the concept and I used it a lot, but it sported an unsightly coil cord (and of course unsightly coil cords have no place on boats) so I decided to build a wireless remote. The system (handheld Tx unit and stationary […]
An Analog & Digital propeller clock i made! It isnt Real its just because your so awfully slow!!! 😉 based on an afterimage phenomenon, ie the reaction slowness of the retina, the illusion of reality our brains are “lying” Picture’s made 12-12-1997 by Luberth Dijkman Clock was actually running 2 weeks earlyer Bob Blick started […]
INTRODUCTION Sometimes it is difficult to judge the ripeness of fruit visually, or we simply forget about our fruits until they are rotten. By using spectroscopy to monitor the change in the color of fruits, this device can track the ripeness of a variety of fruits including bananas and oranges. The system consists of a […]
For another project I started I needed to control the motion of a stepper motor. A stepper motor is used when precision control of movement is needed. With each movement of the motor, the drive shaft steps a precise amount of distance (usually a few degrees with each turn). You can often salavage steppers from […]
Updated 3. Sep. 2002. If you are from Denmark ! read the Danish version !! In the good old days I had some parts but now This Wattmeter is in ELEKTOR MAGAZINE OKTOBER 2002, they will sell PIC and PCB The extra input B is for a later SWR brigde project, also the TX serial […]
Essential when experimenting with PIC. Programs PIC16Fxxx and PIC18Fxxxx series (8, 18, 28 and 40 pins) 16F84A, 16F877A, 18F452 (DIL and PLCC) tested successfully with the IC-Prog software. 18F4550 (DIL) works fine with the PICPgm programmer software. Also programs EEPROMs (8 pins) type 24LCxx with the IC-Prog software. Follow the software configuration steps below to […]
Introduction: We created our own version of Guitar Hero which can play any song that has a MIDI file by using our custom controller and UI. We are big fans of the original Guitar Hero game, but felt limited by its inability to only play a set of songs. We came up with the solution, Guitar […]
Weather station with pressure reading, relative humidity, indoor & remote outdoor temperature display. Both Celsius or Fahrenheit & mbar/hPa or mm Hg supported. With calendar & clock. Easy 3-button user-menu. 42 hour-history display (curve). Auto-memory & display of all high and low-values. PIC 18F452 running at 4 MHz, power saving sleep mode. Sensors are only […]
Microchip’s Digital Pure Sine Wave Uninterruptible Power Supply (UPS) Reference Design is based on the dsPIC33F “GS” series of digital-power Digital Signal Controllers (DSCs). This reference design demonstrates how digital-power techniques when applied to UPS applications enable easy modifications through software, the use of smaller magnetics, intelligent battery charging, higher efficiency, compact designs, reduction in […]
Please check the update at === Digital Clock Updated Version === — Original Version — As I am a WIS so I built a clock as my first microcontroller project. The clock is controlled by PIC16F628A from the PIC book . The idea was making a digital clock with hour, minute and second display. I […]
