Another short minute video on SSTC Tesla Coil project testing. My set-up has an internal primary coil it keeps fingers away from the high current coil but it could have unseen internal flash-overs. If I keep the arcs short it should be ok. ... https://www.youtube.com/watch?v=MYiP2tYZuKk

An old Tektronix Logic Analyser isn’t something you need every day but nice to have. This PRISM 3002 model dates from the 1990s. Even though now long in the tooth it is an interesting instrument packed with technology that can still be useful today. The specification for this analyser, with its two GPX acquisition boards is; 160 channels at 200MHz transitional timing, 32channels at 1Ghz conventional timing, 160 channels at 80MHz state. Its own processor board is based around the Motorola 68010 with 4 Mb RAM and 48Mb capacity MFM hard drive. The unit had been working the last time I used it a number of years ago. Thinking it would be interesting to show it working and to look at the construction, I discovered it no longer worked. Research took me to some Diagnostic documentation and a failure scenario, that occurs when the on-board date/time becomes invalid. ... https://www.youtube.com/watch?v=zQ7H0EK-4i4

An x-ray tube is being used with a fluorescing screen to detect the x-rays and images. I also built the high voltage supply for this experiment. Unfortunately I blew the tripler unit afterwards trying test the maximum voltage. more on this at: http://tuopeek.com/xray_tube.html ... https://www.youtube.com/watch?v=mVG7vhbu9M8

Tungar rectifiers are from a time before silicon diodes and were used in battery chargers. Like a vacuum diode they have a hot cathode and anode. As the current handling can be quite high a carbon anode is used. The one shown here has lost its argon and had air in it. As it was dead it was worth making an experiment out of it. ... https://www.youtube.com/watch?v=NXkVf7fMCEs
