Jürgen sent me this work-in-progress photo a few days ago. But, I'm bad about posting things quickly :(

"For a full length bargraph now the circuity draws only around 300mA @5V --> 1.5VA and this creates 10mA @ 120V --> 1.2VA (only 0.3VA losses); but I must also connect the MC34063A to the voltage doubler circuity (the flying IC "ICL7660" with the two diodes and the two capacitors) and not only the new BC639/640 driver stage for the MosFet...as the converter will shut down when the supply voltage is lower than exact 5V and it should normally just work at 4V."

I now see where I got wrong with all my kits. you see, I was under the belief that the components were supposed to be soldered to the circuit board.

In Germany this helter-skelter up of the board is called a "wired hedge-hog" ;-)

These are really cool tubes. Does anyone know what the intended application was for these tubes?

Let there be neon light!

I would like to purchase one of these kits. Are they available yet?
