Hi guys, back here after a break away. moving house and re-decorating took most of 2014 for me. Any way I have been quite fascinated with water drops, and low level jets but that's for another day. B)

I have been searching on you-tube as you do on how to precisely control the drops of water and have seen the (splash art kit) for around £200.00 which is a fair amount to pay just to get a splash of water. more research needed I thought. I was determined to achieve it by NOT paying that amount.

Well after a couple of months I think ive cracked it :) and it cost me around £60.00 my set up is pretty straight forward using a arduino uno, which is a micro controller that can be programmed to trigger a 12v solenoid. it can trigger up to 3 solenoid's. multiple flash`s. and camera shutter.

here are a few of my early pics, im still learning on how to use it but at least im getting some quite good results. I will post more details later

thought id share.

busy building version 2. ( well a better frame anyway so its not wobbly)
:whistle:

here is the link for anyone wanting to build there own system on the cheap. ( ebay splash art kit is around £500) total cost of my set up would be around £130 when finished.

So how is your arduino sensing the water drop? Can you make a diagram of your setup and what parts you used in your setup? Like what is causing the triggering event? The pressure of the water hitting the target? The motion of the droplet?

@brent ross.

the arduino is controlling the solenoid vales, dropping the water drops in milliseconds.
also it is controlling the camera via a remote shutter cable release.

also controlling any flashes that are connected.

you do not need to turn the lights off like you do with some.

so press start, water drops down camera and flash go off, you have full control of all devices.
Im still very much learning but when version 2 is built I will post some more results.

The website I used to build and get instructions from is from a French guy Patrice champey ( I googled translated all instructions) as I don't speak a word of French :) apart from hello. :) quite a friendly chap who im sure will help anyone wanting to try this out.

watch the youtube videos and follow the link in the instructions



have fun !

Wow man its really amazing shot! Do such shots depend upon the camera set up only or other things also needed?

@jannatul, thanks :)
well the camera is in manual mode, iso is around 200/400
manual focus which you do before with a pencil or anything else in the glass and f18/ f22 so the whole splash is in focus (hopefully)

I was hoping for some new pictures today with my version 2 setup BUT........ er..... it blew up, :( well smoked from the bread board with the important bits on. my fault I didn't solder something right and didn't check. so I guess after my new parts arrive off ebay its

version 3 :) :whistle:
