The technical side of this hobby has my special interest and this is reflected in this home page. The menu on the left will take you to the various parts of this home page.</div> <bR> <div> Among other things you can find <A HREF="id54.htm" TARGET="_top" TITLE="NiCad charger, switch mode."><U>a charger for NiCads or NiMH cells</U></A> as used in radio control. A description, schematics, a PCB layout and a parts list are provided. This NOT a beginners project! To get results it is wise to have a look at the web sites of the manufacturers of the special parts that are used in this project. This was published previously by me in <A HREF="http://www.ezonemag.com" TARGET="_top" TITLE="http://www.ezonemag.com"><U>The Ezone Magazine</U></A> in the articles by Wayne Hadkins. Have a look at this webzine.</div> <bR> <div> Another project was the design and building of a <A HREF="id41.htm" TARGET="_top" TITLE="5 Volt regulator"><U>voltage regulator</U></A> to be used on board of the planes when using five cell NiCads and 5 volt as the supply voltage. In this project very small SMD devices are used. An advantage of this regulator is the fact that switch failure in flight won't cause a problem anymore. Look at the pages to get convinced!</div> <bR> <div> Today it is possible to make servo connector elongation wires yourself by using the special crimping tool that is offered in the advertisements in various modeling magazines. How to use this tool is the topic in a <A HREF="id35.htm" TARGET="_top" TITLE="Servo connectors made by yourself"><U>photo series</U></A> on these pages.</div> <bR> <div> In the English <A HREF="http://www.modelflying.co.uk" TARGET="_top" TITLE="http://www.modelflying.co.uk"><U>Radio Control Models and Electronics</U></A> magazine in 1995 <A HREF="http://www.welwyn.demon.co.uk/" TARGET="_top" TITLE="http://www.welwyn.demon.co.uk/"><U>Ken Hewitt</U></A> published a glow driver that delivers a constant voltage to the glow plug as used in our engines. Because my old glow driver failed and blew some plugs I build this one. I don't like to build on strip board so I designed a <A HREF="id60.htm" TARGET="_top" TITLE="Ken Hewitts GloControl Mk2 circuit and P"><U>PCB for this very well working design by Ken Hewitt</U></A>. I like it very much! Build one yourself and you won't regret it! Be careful however to use the coil mentioned otherwise the driver won't deliver the current needed. All the glory to Ken Hewitt for this application of a switch mode power supply I.C.</div> <bR> <div> On special request I made a <A HREF="id66.htm" TARGET="_top" TITLE="Short manual for the MC4000 in English"><U>short English version of the manual for the Multiplex MC-4000 radio control transmitter</U></A>. I put it in PDF file format. </div> <bR> <div> The use of the charging socket on the serie 30xx and 4000 TX's by Myultiplex is described<A HREF="id68.htm" TARGET="_top" TITLE="Use of the connections on the left side "><U> on this page.</U></A></div> <bR> <div> The Gyro Switch is a device to switch a gyro in and out of the line to a servo. I use this on a Piper Cub that will wander from side to side on take-off. The use of a gyro solves this issue but the gyro should be put off when airborne while rudder control is maintained. This is just what the "<A HREF="id70.htm" TARGET="_top" TITLE="Gyro Switch"><U>gyro-switch</U></A>" does.</div> <bR> <div> On the website of the USA distributor of the Multiplex line it was recently reported that the optical RPM sensor is no longer available from Multiplex. This made me re-open a series of experiments done earlier to make one myself. <A HREF="id78.htm" TARGET="_top" TITLE="RPMsensor for the MC4000"><U>The resulting circuit is presented here. </U></A></div> <bR> <div> Using long servo connections can lead to radio interference and loss of voltage accross the wires. To make the use of a separate battery to power the servo's possible and to suppress the possible radio interfence from long servowires I designed an <A HREF="id96.htm" TARGET="_top" TITLE="Optical servoisolator"><U>optical isolated servo connector for up to four servo's. </U></A></div> <bR> <div> On the internet Ian Stockley-Miles from England posted a question concerning the possibility to connect a FUTABA transmitter to a Multiplex transmitter in a pupil-teacher configuration. <A HREF="id99.htm" TARGET="_top" TITLE="PupilTrainer cord for FutabaMPX combinat"><U>The interface needed for that purpose is presented here</U></A>.</div> <bR> <div> <IMG SRC="1fd1b090.gif" border=0 width="27" height="9" ALIGN="BOTTOM" HSPACE="0" VSPACE="0">Some time ago I started to experiment with video downlinking from a model airplane.
