I'm going out of my mind.  For months I've been trying to build a
simple opti-isolater circuit.  I've seen it hundreds of times in books.
It goes something like this.

                       |||||||||||||                |----####----
      +5 <--- ######---|1         6|---#######------|     load
              r=100    |  moc3010  |    r=180     Triac           AC120
     GND  -------------|2         4|--------------/ |
                       |           |                |------------
                       |||||||||||||


 Please help, Is there something wrong with the above?  The load
I've been using is a 100W bulb.  The Triac is a 400V, 6amp (RS 276-1000);
I've tried many other triacs also, with no better luck.  Pin 4 goes to the
triac gate.

If you've made a simular circuit work, could you let me in on it?  I'm
getting a little desparate.  My only requirement is TTL compatiblity and
no relays or solid state relays.

Please E-Mail, but I'll keep an eye on the newgroup also.

Thanks in advance

Bill
