My third Arduino project was inspired by the second, the Timelapse Slide. This project was to include an existing Manfrotto 454 Micrometric Positioning Sliding Plate. with this slide & a stepper motor I hope to be able to do some Focus Stacking have a look at Zerene Stacker<\/a> the software I intend to use.<\/p>\n

\"\"<\/a><\/p>\n

Attached to this will be another Stepper motor from Robot Gear<\/a>. This is the same one that I used in the Timelapse Slide project. I mounted the stepper to the slide plate using scrap alloy angle I had laying around.
\nThe stepper shaft is 5mm and the slide has a 8mm thread, I just happened to have a 5mm propeller spinner that had a 8mm thread, with a little work I had the stepper fixed & moving the slide.<\/p>\n

Now to the Arduino control, this time I decided to use a Freetronics “eleven”<\/a> board, the Freetronics LCD & Keypad shield<\/a> and the Adafruit Motor\/Stepper\/Servo Shield<\/a> that I used in the Timelapse Slider project.<\/p>\n

The below photo shows all the slide hardware mounted & tested.<\/p>\n

Another view.<\/p>\n

The stepper will now move the slide with 100mm of free movement. I did some testing & one motor step will move the slide 0.0062mm & 1mm of travel will be 175 steps. Slightly different possibly due to my measuring ability.<\/p>\n

So the next step & what I’m working on now is the Arduino menu & control.<\/p>\n

Below is a photo of the Arduino with the stepper shield in the middle & the LCD shields on top.<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

The menu can be clearly seen displayed on the LCD, I’m using phi_buttons library to handle the LCD buttons & the phi_prompt library for the menu items. I have the menu programmed with what I think I need, now to get the menu to control the stepper.<\/p>\n

Its been a while but I have finished the Macro Slide to a point that I can use it. It took a little while to work through the programming of the menu to control the stepper but now I can set the time between shots, the number of shots to be taken & the number of motor steps between each shot. The photo below is the completed Arduino hardware enclosed in a temp housing, powered up with the start menu showing.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

The Arduino is setup to trigger the camera between the motor moving the slide, the camera will be set up independently due to the fact that I will be using the reverse lens technique to capture macro photos. This has proven to be a cost effective way for me to get into macro photography as I already had three older FD canon lenses & the reversing adaptor ring was very cheep through eBay.
\nThe fact that the lens is reversed on the camera means you have to set the aperture wide open with a little trick, then I set the shutter speed via the normal camera method, manual control over static lighting is the last requirement.<\/p>\n

Finally have the entire setup together.
\nHardware
\nManfrotto 244RC Variable Friction Arm
\nManfrotto 454 Macro-positioning Sliding Plate
\nCanon 60D
\nCanon FD 50mm Reversed
\nViltrox JY-675 Macro Cool Light
\nArduino controller, see above
\nSoftware
\nZerene Stacker, see above<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

Now have the Arduino control boxed in its final enclosure.<\/p>\n

 <\/p>\n

Below is a Stack using the Macro Slide. 178 RAW images converted to TIFF & stacked using\u00a0Zerene Stacker. Not happy with the result, might try JPG instead of RAW next time.<\/p>\n

Not sure why it looks like it does, need to look into it.<\/p>\n","protected":false},"excerpt":{"rendered":"
