1-07-2010 | A standard 60 mm x 100 mm piece of prototyping strip board (breadboard) can very simply be used as a 12 V warming plate. All that’s necessar...

1-07-2010 | The LM1830 fluid detector IC from National Semiconductor is designed to be able to detect the presence of fluids using a probe. This chip re...

1-07-2010 | The most recent PC motherboards provide four pin connectors for cooling fans especially for the CPU fan. The older three pin fans are contro...

1-07-2010 | This is a very simple and cheap device that demonstrates mobile phones (US: 'cell phones') generate RF energy (radio waves) strong e...

1-07-2010 | This clock displays the time in binary using discrete LEDs. The use of Flowcode [1] makes it very easy to program the PIC controller in this...

1-07-2010 | Each grid uses figures from the hexadecimal system, i.e. from 0 to F. Fill in each grid in such a way that all the hexadecimal figures from...

1-07-2010 | A tilt sensor is a very versatile device: for example, it can be used as a (game) controller or as an alarm sensor to protect valuables. The...

1-07-2010 | PP3-size 9 V batteries (IEC: 6LR22) have a considerably poorer price/energy ratio than 1.5 V AA (IEC: LR6) cells. This makes it all the more...

1-07-2010 | Given that every PC has a powerful, well-regulated PSU that supplies, among other things, a 12 V rail, why not make use of it to produce a P...
