| Visiting prolific collector and author of many books John V. Terrey with Chad Shapiro | |
| I'm happy to have been able to get many of John's medical books. He has an amazing library! | |
|
I also scanned an extensive collection of materials I have on
spectroscopy/ultraviolet/X-Ray/photography pioneers Josef Maria Eder &
Eduard Valenta from Vienna. (It's only a drop in the bucket, I have a lot!) |

Hydrocarbon Quenched Spark Gap
Photos I first made this gap in 2014 after some experimenting in 2008. This gap really works well in spite of the many dangers and explosion hazards of using hydrocarbons for quenching. Of course this is for historical reference only, these forms of gaps are extremely dangerous! |
