  • Be Foolish More Often In Engineering
    As engineers and technical professionals we are all trained to be logical and rational and rely on proven facts in making decisions. The approach with engineers is to vigorously apply the blowtorch to any concept which is rather nebulous and stick to solid engineering design practise. However as Margot Cairnes, an Australian leadership strategist recently pointed out: ‘This often means being conventional, boring and underperforming (when creating solutions to difficult problems). In a changing Read More...
  • Advantages And Disadvantages Of The TC74 And The DS18B20 Digital Temperature Sensors
    I have recently worked with 2 different digital temperature sensors and I want to discuss some of the pros and cons of both sensors in this article. The first one was the DS18B20 from Maxim (used to be Dallas Semiconductors). The package was the TO92 which is a small three terminal transistor type. The interesting part about this device is that it has a one wire interface. This means that apart from Gnd and Vcc, there is only one communications wire between the interrogating device, usually a mi Read More...
  • Practical Development Kits Using A Pic Micro And A Maxstream Xbee Wireless Module
    Development kits in the field of electronics can cover many different types of systems from the simple demonstration of a devices capabilities using switches and LED's to complex multiple microprocessor setups with lcd screens, sensors and other man machine interfaces. One thing they all usually have in common is that once one has worked on a system and become familiar with a device then the kit is packed away and gathers dust in some corner and the designer must then take the next step of desig Read More...
