Hi, I'm an amateur electronics enthusiast in China. A few years ago,I bought 20pcs of NEC LD8140 VFD screens,and tried to light it up. In the beginning of the year 2012, I designed a VFD drive circuit without using transformer, and I published it in the "China Radio Magazine 2012.05".From then on I started to create a few EE stuffs with VFD/OLED/Nixie Displayer.This was so much fun.
Now I post my articles on this new website to share with all the enthusiasts, hope these articles can help you improve your work. The original articals which I published here were written in chinese,but I'll try my best to translate some of it into english.For now you can try to read it by using goole translate app.
