If there’s one important merchandise for macro pictures, except for a macro lens (or extension tubes), it’s a macro focusing rail. We’ve featured a number of focusing rails right here on DIYP earlier than, just like the NiSi NM-180 (assessment right here), in addition to another DIY options. This one, from Curious Scientist, is an ongoing mission based mostly round an Arduino Nano that makes use of a stepper motor to maneuver your digicam alongside a rail in nice increments.I say it’s an ongoing mission as a result of since releasing his first video on his motorised macro rail slider solely a month in the past, he’s already posted an replace displaying virtually an entire redesign of the staging platform on which you mount the digicam. Relying in your digicam and wishes, both design would possibly work very properly for you, so I’ve included his movies under for each of them.The primary design, posted a month or so in the past, is basically the way you’d anticipate a macro-focusing rail to look. It truly resembles the NiSi NM-180 talked about above, besides that it has a motor on one finish of it as a substitute of a manually turned deal with. The electronics let you set begin and cease endpoints, and it calculates the variety of photographs based mostly in your aperture, depth of subject and different settings.It additionally retains monitor of how far by means of the taking pictures sequence it’s, letting you shortly see at a look how a lot work remains to be left to do. In the end, it presents you with an array of photographs you possibly can then load into Photoshop or your picture modifying software program of option to create your stacked macro photograph with every little thing in focus, simply the best way it must be.The second design reveals a really completely different and far more elaborately designed staging platform. It appears to be like extra like a tiny digicam slider fairly than a macro-focusing rail, nevertheless it ought to add far more stability to the system because it strikes from one shot to the subsequent. This lets you use bigger, heavier digicam rigs in addition to offering extra exact management for smaller topics with a lot shallower depth of subject.AdvertisementsBoth {hardware} designs are very fascinating, and which you would possibly select to construct will rely by yourself wants, however the electronics to energy each are an identical. They’re each fascinating tasks, and I believe the design of the rail itself is probably extra fascinating than the electronics or the software program. Thankfully, he’s made the 3D information (for the second model) out there to obtain from his web site.The PCB information, nonetheless, you’ll have to buy by way of PCBWay, and the supply code for the Arduino is barely out there to his Patreon supporters. Hyperlinks for each of these are additionally out there on Curious Scientist’s web site.Macro is an entire lot of enjoyable, particularly when you possibly can automate among the processes to take human error out of the equation. I’ve been desirous about attempting to motorise that NiSi NM-180 ever since I bought it, however how easy the mechanical designs for these are, I might need to consider simply constructing one from scratch!AdvertisementsFind out all about Curious Scientist’s first design right here and his second design right here.[via Hackaday]
