High-voltage flyback transformers look like a dying breed these days. All the experimenters seem to get them either from old CRTs or random eBay surplus sources. But my project needs to be replicable from standard parts on the product catalog of a big vendor, so random components are unacceptable. CCFL lightning transformers seemed to be a good source in the past decade, but most are discontinued in this LED age. I guess I'll just stop wasting time and use a pre-made SIP DCDC module instead. #electronics
