Wattmeter with an Arduino - It is difficult or sometimes even impossible to measure power and energy with ordinary multimeters.  To carry out such a measurement reliable and accurate, a special wattmeter is required.  Because these meters are very expensive, a cheaper solution is presented here as a DIY wattmeter based on a Arduino Nano board. __ Designed by Freddy Alferink

WIB: Web Server In a Box, Part 1 - We're very excited about this project.  It will let you house your own website with possibly hundreds or even thousands of pages, all in a little box connected to the internet via your modem/router.  You don't need a computer to operate and house a website - this little box does it for you and it can be accessed from anywhere around the world, at any time, even from a mobile phone which has a web browser.  In fact, it is a complete web server in a box - so we've called it WIB  (Web server In a Box) .__ SiliconChip

WIB: Web Server In a Box, Part 2 - Last month, we introduced our new Web Server In A Box  (WIB) and gave the full construction details.  This month, we show you how to connect it to your modem/router and guide you step-by-step through the set-up details.  We also show you how to activate a dynamic DNS service, so that you can access the WIB via the Internet.__ SiliconChip

WIB: Web Server In a Box, Part 3 - In Pt.2 last month, we showed you how to connect the WIB to a network and gave the step-by-step setting-up details.  Most constructors will settle for the website provided but for those with special needs, this third article is for advanced users who want to customise the WIB to their requirements.__ SiliconChip

Wind gauge - On this page, I will introduce the wind gauge using PIC.  There are various methods of measuring the speed of a wind.  With this equipment, a hemispherical window cup is rotated and the method of measuring wind velocity at that number of rotations is used.  The measured number of rotations is sent to a personal computer with a USB interface, and wind velocity is displayed on a screen.   __ Designed by Seiichi Inoue

Wireless controlled light dimmer - The meaning from this design is to build it in -i.  e.  a shaded lamp- and to switch this lamp on and off the normal way, just like it was switched before the dimmer was build in, then you could by exception dimming the lamp more or less with your TV remote control.  When you switch the power on there will follow a soft-start till the lamp burns at the previously adjusted dim level.  With the '0' button in TV mode you can dim the lamp, turn more and less bright.  The remote control should send more than one RC5-signal per button-press seeing that the first one is ignored, this does imply that when the remote button is pressed a short time, there nothing happens.  With the P+ and P- button from a system at choice you can adjust the maximum and minimum dim-levels and with the '1' button the start-up brightness.  

Wisp628 ISP Microchip PIC Programmer - The XWisp program can be used to control the Wisp628 hardware.  This program can be used on Windows  (95 or higher) , either from a DOS box command line or using the windows interface.  It is available as Python source.  It requires that a suitable Python  (2.1 or higher) and the Python for windows extensions are installed.  The XWisp program supports the full range of target chips supported by Wisp628.   __ Designed by © © 2002 Van Ooijen Technische Informatica / Wouter van Ooijen

WLoader: PIC16F877 application loader/Bootloader - If the piclist is an any indication the 16f877 seems to be the new favorite hobby microcontroller, a position that used to be occupied by the 16f84/16c84.  Compared to is older brethren the 16f877 has much more to offer at around twice the price.  As for all Microchip controllers the datasheet  (pdf) and the MPLAB assembler IDE are available for free.   (Microchip keeps changing its website, so when these links turn out to be invalid you might have to look around a little.)  __ Designed by © © 2002 Van Ooijen Technische Informatica / Wouter van Ooijen

X-10 filter - X10?  X-10 is an ancient powerline communication protocol that refuses to die because it runs over existing mains cabling, and is deceptively easy to get started on.  Once you actually start, though, you'll notice that all the modules are very expensive for what they contain, but the worst thing is that the communication is not even close to reliable in modern household. __ Designed by © Madis Kaal

YoYo enhancement Device - The original yoyo was equiped with 2 LEDs that lit up whendevice was spinning.  I decided to add a micro to give it some extra pazazz.  The trick here is to makeunit work without a power switch.  The mercury switch is positioned so that it supplies power whenunit is spinning.  After about 20 seconds, PIC shuts down in sleep modes,  __ Designed by Luhan Monat-Mesa Arizona
