2019-07-25 – The list price of the well-designed Vela One has recently dropped. I originally quoted it at about $1,750 CAD but unfortunately don’t have any proof. As of today, the Vela website indicates it is exactly $1,526.70 CAD. The archive.org website shows that the price has indeed fluctuated over time.
2019-08-01 – A big THANK YOU to NQTRONIX who has kindly gifted me an active light probe of his own design. The probe will be used with an oscilloscope to measure the flash duration, trigger response time, light output -v- current, and other helpful things. I will update this post with the data once testing commences. NQTRONIX put a TON of time into designing, testing, and optomizing his probe. Please consider checking out his instructable page and leaving him a like or comment!
Named in honour of the legendary Papa Flash.
Some time ago I designed and built a ballistic chronograph and used it to take some high-speed photos of bullets striking glass. The results were great, but the photos were somewhat limited by the standard ‘speedlight’ flashes that I used – there was always some motion blur. Edgerton is a ‘High-Speed Flash’ which uses LED’s to make one-microsecond flashes to freeze motion.
