GPIB to USB converter with the Pic-plot

Pic-Plot2 GPIB to USB converter

# Low-cost GPIB controller # Controls up to 14 instruments # USB Plug-and-Play # LabVIEW drivers

Due to the very high prices of comercial usb-gpib-adapters I tried to build one with a Microcip PIC18f2550 which has just enough I/O-pins, an USB-interface and is quite cheap.

The xPL Project was started in January 2003 by Ian Lowe and Tony Tofts. It’s goal: To create a unified protocol to allow the control and monitoring of all devices within the home, whilst maintaining an unparalleled level of simplicity and ease of use. During the first half of 2003, the protocol was refined to include powerful auto-discovery and configuration capabilities. With the core protocol now in place, much of the work involves integrating xPL support into software and hardware devices.

The DS18B20 is a very small thermometer which can be easily hooked into the Arduino MCU through any digital input! It requires very little in the way of additional support, a couple of resistors and some hookup cables and you're set to go. For more information on the DS18B20 check out [Maxim-IC].

OneWire Library OneWire lets you access 1-wire devices made by Maxim/Dallas, such as temperature sensors and ibutton secure memory. For temperature sensors, the DallasTemperature library can be used in conjunction with this library.

Your Arduino can tell you. With an Arduino board and a DS18B20 digital temperature sensor, you can easily build a digital thermometer, a thermostat to turn devices on/off at certain temperatures, a safety device to power off when something gets too hot, etc.

Les compteurs électriques récents disposent d'une sortie à deux fils émettant en temps réel la consommation de votre installation : la liaison téléinfo. Les données étant présentes, il est dommage de ne pas pouvoir en disposer ! Nous allons y remédier. L'idée de base est de récupérer la consommation et de pouvoir la suivre de n'importe ou.

An old rotary phone can be used for a number of purposes in your Arduino projects - use it as a novel input device, or use the Arduino to interface a rotary phone to your computer.
