TIP OF THE DAY: CHANGE CASE OF TYPED TEXT IN ANDROID KEYBOARD

Most of us know how to change case before we type a text. But how to change case of a typed text from small-caps, ALL-CAPS, Initial-Caps? It's easy.. * Double tap to select text. Use arrows to expand selection as needed. * Use the ⬆ arrow on the keyboard to cycle through each option. Simple, isn't it.. share if you liked it..

Focus Stacked Bug

Today morning, my son found a dead bug with bright colors around our home. Suddenly I realized the opportunity for a stacked photo and swung into action. I wanted to do it for a while and this was good chance before the colors go away. below are couple of selected ones.

First Focus Stack using automated Rail

I tried to do the real stack using the automated setup. Below is the picture of the final image. Because of the shallow depth of field, I had to do a stack of 64 images to cover the scene. This is next to impossible to do manually. To put things in perspective of the magnification, I have added a hair as well in the frame.

Focus stack automation - Rail Integration

As posted last time, I had received the rail. I have it integrated now. Also, i have implemented the camera triggering aspect. I am using opto-isolator for that. I got it all put together. Now I can use it for taking photos as expected. Here are some pictures of the setup.

My first Focus Stacked Macro Image

While I am trying to make the automation to do the focus stacking, it is also important to try out the stacking manually.  Today I did my first ever macro focus stacked image of a flower. Setup: three extension tubes (36mm + 20mm + 12mm = 68mm) and reversed 50mm lens.  This gives a 2:1 macro (double size) image.  Here is the setup and the result.  Its a stack of 10 images done in photoshop.

Focus Stacking Automation, First proto is ready

Hi there, I have an update on the project. I was able to, at last, make everything into a prototype mode. It is working and getting into some shape.

Aurdino for macro stacking - testing the water

I had ordered some of the necessary elements and have started to do some of the basic stuff with each. I am yet to get the rail itself and it may take some more time. But for the testing I have just connected two wheels to the Stepper Motor. What I have now: 1) Aurdino Uno 2) Stepper Motor 3) LCD Display, 16x4 4) Keypad, 4x4 5) Easydriver for Stepper Motor And accessories like Breadboard, Jumper wires, multimeter..
