One of my favorite shooting techniques is focus stacking. Many pictures on [email protected] site are made using this technique. I use Helicon Focus for post processing and even though this program has camera control built-in, it obviously requires a computer close to the object of shooting. In order to be able to control my camera in the field, I wanted to replace a laptop with simple lightweight controller able to move focus of camera lens and take pictures between steps. In this article, I will show how to build one from Arduino, USB Host Shield and several small parts.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
