Motorized Stage Finesses the Microscopic World

No matter how fine your fine motor skills may be, it’s really hard to manipulate anything on the stage of a microscope with any kind of accuracy. One jitter or caffeine-induced tremor means the feature of interest on the sample you’re looking at shoots off out of the field of view, and getting back to where you were is a tedious matter of trial and error.

Mechanical help on the microscope stage is nice, and electromechanical help is even better, but a DIY fully motorized microscope stage with complete motion control is the way to go for the serious microscopist …read more

Pimp My Scope

Most of us have heard some form of the adage, “You can buy cheaper, but you’ll never pay less.” It means that cheaper products ultimately do not stand up to the needs of their superior counterparts. Hackers love to prove this aphorism wrong by applying inexpensive upgrades to inexpensive tools to fill up a feature-rich tool bag. Take [The Thought Emporium] who has upgraded an entry-level microscope into one capable of polarized and dark-field microscopy. You can also see the video after the break.

Functionally, polarized images can reveal hidden features of things like striations in crystals or stress lines …read more

Simple Mechanism Gives Support for SMT Assembly

With the fine work needed for surface-mount technology, most of the job entails overcoming the limits of the human body. Eyes more than a couple of decades old need help to see what’s going on, and fingers that are fine for manipulating relatively large objects need mechanical assistance to grasp tiny SMT components. But where it can really fall apart is when you get the shakes, those involuntary tiny muscle movements that we rarely notice in the real world, but wreak havoc as we try to place components on a PCB.

To fight the shakes, you can do one of …read more

Repairing a Wounded Mantis

While it’s true that we didn’t specifically say making Hackaday staff exceedingly jealous of your good fortune would deduct points from your entry into our ongoing “Repairs You Can Print Contest”, we feel like [Sam Perry] really should have known better. During a recent dumpster dive he found an older, slightly damaged, but still ridiculously awesome Mantis stereo inspection microscope. Seriously, who’s throwing stuff like this away?

Apparently, the microscope itself worked fine, and beyond some scratches and dings that accumulated over the years, the only serious issue was a completely shattered mount. Luckily he still had the pieces and …read more

Not So Simple LED Upgrade for Microscope

[Amen] obtained a microscope whose light source was an incandescent bulb, but the light from it seemed awfully dim even at its brightest setting. Rather than hunt down a replacement, he decided to replace the bulb with a 1W LED mounted on a metal cylinder. The retrofit was successful, but there were numerous constraints on his work that complicated things. The original bulb and the LED replacement differed not just in shape and size, but also in electrical requirements. The bulb was also part of an assembly that used a two-pronged plug off to the side for power. In the …read more

Hacking a Metallurgical Microscope

[Amen] wanted to inspect ICs on the PCBs for suitability for reuse, so he bought a metallurgical microscope that illuminates from above rather than below, since it normally looks at opaque things. It has a working distance of 0.5 and 10mm, which isn’t a lot of room to solder.

The microscope didn’t come with a slide tray, so [amen] found a cheap one on eBay. Needing a connector block, he melted down some food trays into an ingot, which he then milled down into a block shape, drilled, and used to attach the slide tray to the microscope.

The thing …read more

Speakers Make a LASER Scanning Microscope

We’ve seen a lot of interest in LSM (LASER Scanning Microscopes) lately. [Stoppi71] uses an Arduino, a CD drive, and–of all things–two speakers in his build. The speakers are used to move the sample by very small amounts.

The speakers create motion in the X and Y axis depending on the voltage fed to them via a digital analog converter. [Stoppi71] claims this technique can produce motion in the micron range. His results seem to prove that out. You can see a video about the device, below.

Oddly enough, [Stoppi71] found that older CD drives were easier to work with …read more

Microscope DSLR Mount Using PVC & Heat

Microscopes are a great way to see the mysteries of the universe hidden at the smaller scale. When they were first developed, scientists had to rely on illustration to convey their findings through the lens. Thankfully we can  now rely on photography to help us out instead. Many microscopes come with a special port — often called a trinocular port — for mounting a camera. Using this, [Brian] developed a DSLR mount for his microscope using a hacker staple: PVC pipe.

The virtues of PVC pipe are many and varied. It’s readily available in all manner of shapes and sizes, …read more

Laser Scanning Microscope

Remember that feeling when you first looked down on a microscope? Now you can re-live it but in slightly different way. [Venkes] came up with a way to make a Laser Scanning Microscope (LSM) with mostly off the shelf components that you probably have sitting around, collecting dust in your garage. He did it using some modified DVD pick-ups, an Arduino Uno, a laser and a LDR.

To be honest, there’s some more stuff involved in the making of the LSM but [Venkes] did a detailed Instructable explaining how everything fits together. You will need a fair dose of patience, …read more
