This was a week-end project I created from a 6" black and white TV and a large neon bulb a friend sent me from overseas,
the smaller bulbs I found at a second hand store, I wish I didn't have to say this, but this project uses VERY HIGH VOLTAGES,
it uses the out put voltage of the TV's flyback I'm not sure the exact voltage but I'm guessing around 20,000 volts, it can burn, cause a heart attack and is just plain miserable.
The total cost to me for this project was about 20.00 dollars, the TV was 5.00 and the wood and doo dads the remaing cost.
These little TV's are in all the junk shops they no longer work without a digital converter, and B+W is too boring for most people now.
Step 1: find the parts and test, safety.
Because it's been 30 years since I studied electronics I took the easy way out, I just used the whole circut board from the TV chassis.
I cut off the leads to the vertical and horz magnet drivers, and the heater in the tube, this left me with a single board which had the coveted flyback, I also cut off the tuner section of the board because it stuck out another 3'
To be simple I cut every wire to the tube, the large single wire to the side of the tube is what you want to use, if you didn't know that, then don't start this project.
Pay attention! TV Tubes store their voltages for quite a while, days, weeks, months, so when you disconnect the flyback wire from the side of the tube treat it as if it is on running at full voltage, I grounded mine with a pair of gloves and a screw driver connected to the TV ground,
then I put tape over the hole on the side of the tube so as to not acidently discharge it into me.
If you are going to get shocked this just might be the time, get help if you need it please!
