1-07-2001 | A temperature measurement system with up to eight distributed temperature sensors can be realised using only a single signalling lead. This...

1-06-2001 | Moving signs are a common enough sight today but off-the-shelf units are invariably expensive and somewhat inflexible. The six-character mod...

1-03-2001 | Although 8-bit operation is included in the IDE interface, most hard disk drives do not support this mode. If you nonetheless want to contro...

1-02-2001 | The universal RF matching network described in this article is particularly easy to use, adapt using (free) software and last but not least,...

1-12-2000 | Most modern handheld transceivers for 2 m and 70 cms ham radio incorporate MOSFET RF power modules and are capable of operating at supply vo...

1-10-2000 | When this interface is connected to an extended parallel printer port (EPP), your PC can communicate using the I2C protocol, and it can also...

1-09-2000 | Everybody is talking about the USB. In the long term, this new serial interface could replace many of the PC interfaces that have been used...
