    As a member of MERG. I have been looking at the MERG Stepper Motor Turntable Operation for long time. after reading through the forum, I decided to have ago.
    I ordered the pre programmed PIC and the PCB from MERG, and the components from RS Online and Rapid.
    I made a start on the PCB putting the components on that was not to bad as in the component list there is a list of numbers and that correspond to the PCB.

     

     
    I have not put in the IC's until I have done the first test.
    This the back of the PCB showing the soldered components.

     
    I am still waiting for some compasitors to come, but when I get come I will put them on the PCB then fingers X'st test the board to if all is ok, then I will put IC's in.
    Then I turned to the control hand set, there is no instructions on how to build the box as it is to your own preference but there is a wiring diagram that you can go by.
    The box I got from Maplins, I had to plan out were I was going to put the components, the 16way hex switch (the postion switch)I soldered to a peace of stripboard and drilled the hole for the shaft to go through the I attached to the box, then I drilled the holes for the switch (haed and tail) /push button (run/stop) and the LED, as you can see on the stripboard I had to cut the copper strip to isolate the two soldered joints,

    Here is what it looks like inside the box.

    The H and the T is for the head of the bridge or the tail of the bridge to go to the place you wish to go to.
     

    The top end of the box I drilled two holes for the wires from the PCB to go into the box and soldered to the stripboard make a note of what colours go were, the other end of the wires, I have put the socket pins on the wires then put the right colours in the right place in the plastic housing so each wire corresponds to the right pin. I used CAT5 cable complete with plugs on each end, I found it cheaper then buying the cable by the metre.

     
    Here is some pictures of the finished hand set.

    This is as far as I have got for the moment. I will try and take a video of the operation when complete

    I got the capacitors yesterday and soldered them in this morning, I then connected to a 15v transformer and done the test and the test went first class know I was able to put the IC's in there sockets plugged in the two plugs from the hand controller and the stepper motor and all is first class IT WORKS, I am a very happy chappy.
    I have done a video and have uploaded onto You Tube. Click on the link below to see the video.
