       Best wishes to you and yours in 2016.

       Another year has passed. This year, I hope to get my image orthicon camera operational and to begin or complete my [color flying spot scanner] project. The latter being several sub projects that will be combined together to form the entire system. There will be smaller projects too. Some more work on [color mechanical TV], my [amateur television (KJ6RNL) station], [cathode ray tubes] and more clever video circuits.

       As a person prone to episodes of low grade chronic depression, my projects operate in a start-stop mode. The struggles with the old camera taxed me and I have become frustrated with it. It is a project that will be completed as I owe this to my dear friend, John Turner at [Turner Engineering] for his selfless help in shipping the camera to me safely from the east coast. If you need professional services, facilities and equipment for your professional and industrial television production needs, Turner is your only choice.

       When I resume the IO camera restoration, hopefully soon, I must address a suspected instrumentation issue. I measured excessive current drain and have been stymied by this. I am unable to find a single thing to cause this condition. Then I started to think about the 8 dollar Chinese digital 100 amp ammeter I purchased on line. It never occured to me that it could be inaccurate. Did I mention the 8 dollars? You do get what you pay for.

       The color flying spot scanner will consist of a premade commercial professional Telemation sync generator unit, a premade commercial professional Telemation NTSC encoder. Along with this is the "projector unit" which will contain the scanning CRT and support circuits. The optical unit will have a holder for 35mm slides, dichroic mirrors and three photomuliplier tubes with power supplies and preamps. This is essentially four partly separate projects.

       Also waiting in the wings is a return to my 32 line NBTV mechanical television set. I have some more LEDs, diffusers and circuit ideas to test. My newest acquaintence, [James Hawes], has been discussing many good ideas with me via the new fangled electrical mail system. How many mechanical TVs use trichroic prisms to combine the red, green and blue light sources in color mode?

       Can you believe it? The [Tiny Triniscope ] turns two years old next month! How time flies!
