ELECTRONICS - [designs & projects]
Knight Rider lightcomputer : This little circuit creates a light effect like the car in the TV serie 'Knight Rider'. I designed the circuit for a friend.
Counter Device : This device allows you to measure the time, a certain contact is open. This time is showed on a few displays, in seconds.
Soldering Station Protection: Small circuit with a button you need to press, in order to get power for a soldering station for 30 minutes. After this time, the power is cut off, unless you press the button again. This circuit is to prevent that the soldering station wasn't turned off, and keeps active for days.
Alarm system: I had an assignment to design a home alarm system, based on the PIC 16F84A microprocessor. The circuit is protected against sabotage and 220V power failure by a powerful battery.
I²C I/O board : These pages explain a I²C based I/O board for microcontrollers. This was an assignment for school, last year. This circuit can be used as I/O board for the 8051 microcontroller.
PIC programmer: This project is about a little PIC programmer. The schematics were found on the internet, and I now am trying to build this little circuit so I can create my own microcontroller applications. For copyright reasons, the circuit cannot be found on this site. View a tutorial (http://www.circuitsonline.net) on PIC microprocessors, with software & programmer circuit available. This article is written in Dutch, but very useful.
