DIY audio trigger for camera

Recently I’ve been thinking to make a photographic Triptych. I wanted to show the stages of a balloon being inflated and then popped. In order to capture the pop and expression of the person while popping the ballon I will have to pop lots of balloons. So I got the idea of using a sound trigger . Arduino would be the initial thought but I said it can be done easier. There are so many light switches that respond to claps. After some researche on the web I found an electronic kit tha does something similar to what wnat. It’s an audio device used as music visualiser , with 5 LEDs that flash brighter with higher volume. That’s an excelent start , cause instead of the LEDs I can use a relay. But to make sure it’s electronically isolated from the camera trigger circuit I used a octocoupler or optoisolator.

Perfect gift for Valentine’s day

The modern origins of Valentine’s Day come from England. The first real association of Valentine’s Day with romantic love, or “love birds,” comes from Geoffrey Chaucer’s poem Parlement of Foules. Dating from 1382, it states: “For this was on St. Valentine’s Day, when every bird cometh there to choose his mate.” William Shakespeare’s Hamlet (1600–1601) refers to both Saint Valentine’s Day and the phrase “to be your Valentine,” showing that Valentine’s Day was established in British culture by that time.

Evening walk in Maids Moreton and Foscote Reservoir

Last evening I went on a short walk on Foscote Road to the reservoir in the hope I would get some nice birds in flight with the Nikon Z6ii and the mighty 70-200 f2.8. I like using it for landscape also ( see picture above from almost sunset ) . The only shot I got was one wild duck flying over a swan … but then I wanted to check the close-up shots with the lens and I have to admit it’s amazing to get as close and still be able to focus. I helped the focus by manually focusing to closes point and let the AF do the job from there. It was able to capture these small blue dragonflies – images are cropped and size reduced for website though.
