Hi ION
Good to see you still around and active, no i have not yet followed up from the bulb blackening, but i have built a vacuum chamber that i can inject nitrogen and have a vacuum pump now, some time ago i had to step back from some projects, i had too many going on that were not getting completed, i had a hard long think while still doing work around the house constantly, and decided first to finish my 3D printer over the last 2 months i completed that, it's only taken 2 years to build it from scratch on and off, so it was really nice to finish that and off course this now puts me in a position that i can print coil bobbins and any other device.
The Meyer device has been a priority but i realized it was taking up loads of time with very little return and the problems i was facing were beyond easily sorted by me, ie 1kw power at 45MHz. it was this that triggered my rethinking.
So next i will be completing the Nitrogen chamber and follow with that, i still have another project on the go though, since the 3D printer was finished i stupidly decided to build a coil winder see pictures below, so have also been writing software in some evenings to get this up and running while waiting for parts from China.

Image2 Coil Winder structure has been printed, waiting for bearings from china, the light grey thing in the middle is the carriage, include guide wheels with bearings, 2 felt spring tensioners and an in and out guide.

EDIT the coil winder is not my design, the guy finished all the mechanics but did not publish any electronics, as i can do the microelectronics myself and the mechanics are brilliant i could not resist it, i made my machine bigger, it's capable of 40cm long coils at upto 20cm diameter.
Design is here.
My thanks go out to Nico Verduin, i will publish my computer files when finished and running.
