ELektronik Kompendium

Two new circuits with AVR: Universal timer and frequency clock, in addition new software for the ATTiny11-Programmer, in order to be able to program also Tiny12 and Tiny15.

ELektronik Kompendium

Two new circuits with AVR: the fluorescence indicator control with HD44780-Emulation and the simple radio clock with various indicator options. In addition a Perl Script for the RS232-zu-LCD-Konverter for the use with XMMS.

Second update: Transmitter circuit for the RS232-Interface without Microcontroller with 8 entrances, in addition the texts somewhat revises and restructures.

16-bit to seven-segment

16-bit to seven-segment

“This circuit is used to represent a binary word (up to) 16-bit to seven-segment displays. Changes the binary word, the display is updated immediately. If fewer than 16 bits are displayed, the unused inputs can be connected to ground easily. A switch between six different display modes can be switched”

CAn Remote Automation-Control with AVR

CARACA is a home automation project based on a net of interconnected programmable circuits suited to perform different tasks like switch on/off appliances, decode commands from Ir remote control units, control thermostats, measure temperature and more.

CAn Remote Automation-Control with AVR

Every node of the net communicate each other through a robust protocol (CANBus), and the status can be monitored by a PC possibly connected to the Internet.

Other Open Source Home Automation Projects

MisterHouse: Home Automation with Perl
MisterHouse is a Windows/Unix home automation program written in Perl. It can respond to voice commands, web browsers, time of day, serial port and X10 data, external files, etc and can speak via Text to Speech engines.

OpenRemote – Home of the Digital Home
Software for the Internet-enabled Home at openremote.org. An Open Community in the Home Automation and Domotics space. We believe an Open Source approach can revolutionize the way people create, install, and maintain software in the industry.

PICuP ProtoBoard – BitScope Designs

ProtoBoard started life as ProtoPOD.It was designed as a prototyping POD for use with BitScope making development of new (PIC based) POD designs easy.

PICuP ProtoBoard – BitScope Designs

PICuP ProtoBoard

It is a small (2.6″x4.0″) PCB comprising a 20 x 13 thru-hole prototype grid pre-wired with 4 busses and a 40 or 26 pin header with pads for connections into the circuit.

Application

PIC ICE Probe – When you need to analyse an existing circuit that has a PIC in it you may wish to observe signals at the PIC pins to diagnose a fault.

Data Logging – ProtoBoard includes a serial interface which can be used as the basis for any number of data logging projects. The PIC may be programmed to monitor some external variables and then transmit the data to a remote PC as required.
