Hey fellas,
Working on a little eye candy project for my wife..... I will nestle a ITM2M cube ( when my CD4060 IC arrives ) between these flashing IV15 bulbs I got from jrehwin. He was kind enough to help me out not only with hardware but setting them up. Thanks again big guy!
I took some videos for you guys show the differnt speeds of oscillation that is adjust through the resistor cap combo.
Also included is a schematic of the original idea. Mine is adjusted slightly to provide 5V to the filaments and 165V direct to the anode through a current limiting resistor. ALso some literature of testing others have done. ( Similar to the DM160 but the IV15 is cheaper )
Any one have a dozen they want to sell? LOL

Hope you all enjoy the simple osc circuit and videos.
Thanks again John!!

LOOKS AWESOME.
What method of driving did you do. Any schematics. Just curious.
Thanks for posting
