I was always fascinated by lightning. Long time ago, being a teenager I shoot lightning strikes many times with some degree of success. At that time I was using my dad’s old Zenit camera. While lightnings are always the same, equipment advances very rapidly. Today I will talk about spotting interesting frames from video and detecting exact moment of strike using Python.
To be short I will be talking about long term tethered time-lapse photography (it is also a good platform for construction camera). While final movie can be very short this kind of photography involves lots of planning and technical skills. During long time time lapse project a lot of things can go wrong. Also prepare to ruin your DSLR if you are using one.
I was impressed by freshly released Raspberry Pi 2 Model B. It has even larger possibilities than previous versions because of it’s quad-core higher speed BCM2836 ARMv7 CPU and twice larger RAM. Also I was very happy that mechanical layout was almost identical to Raspberry Pi Model B+, which means no need to redesign existing enclosure.
This is my second trip to China and I could not resist dedicating a post about it. China is a very beautiful and warm country. Also this is land of “Made in China”, so it is also a land of many many manufacturers. Few days for wandering around and finding out about this country from inside is very little. But I am glad that I was able to go there anyway. It was fantastic experience for me. I would definitely like to stay there for a longer time.
Good news. This beautiful aviation grade sandblasted black anodized Raspberry Pi B+ case is now available. Raspberry Pi fits just perfectly now. This is v2 revision of industrial RPi B+ case. Take a look at some pictures below.
In addition to Logitech C920 case since now I have also custom made IR blocking filters. These are high quality thin (0.2mm) optical glass filters that blocks all IR light. Picture quality
is as good as original filter sourced from Logitech lens assembly, well quality is good enough but filtering range is not that good. First batch mistake – working on improvements.
