Some more water drop photos and some technical updates.[Original Photography]

Hey peeps.

So another session with the water drip kit. This time I tried a new liquid. This is water mixed with something called "Tylo" which is used by cake makers to make edible glue. It effectively thickens up the water a bit. I actually think i did it too thick though :(. I also added some milk to increase opacity and then added food colouring. I did some drops with just a purple colour into water and then some with purple into orange. Turned out OK. The first two look like glass. I think the first one might be a relative of @carlgnash.

For the combination of purple and orange, the liquids were way too thick and i couldn't produce double drops easily. Turns out that you only need the tinyest amount of Tylo, not half a teaspoon.

Here's a quick look at the colours in their original form :)

Also made some technical changes and replaced the LCD screen, buttons and pretty much everything with a phone app. This is created with an app called "Blynk" which enables connectivity to many IOT devices, one of which includes the Arduino. It's a load easier to control than with the LCD and will enable me to have a final product that is way more compact than the prototype.

Thanks for looking
