Machine your own Ring Light

[Alan] acquired a stereo microscope from eBay, and decided to save some more money by designing, machining, and assembling his own arc reactor ring light to go along. After finding an LED driver board sitting around as well as ordering some surface mount LEDs, he set about using a lathe to cut away a block of lexan, making sure to include slots for the lights as well as the microscope mount point. Follow the link to see the detailed build photos, as well as some comparison shots with and without the ring light.

A month or two earlier though, and [Alan] would have had a fantastic start to an Iron Man costume.

Surgical microscope gets LED retrofit

[Roberto Barrios] picked up a surgical microscope to add to those other fun lab toys you seen in the background. These work very well when soldering small components because they don’t have to be as close to the viewed objects as traditional microscopes. But [Robert] didn’t care for the heat generated by the incandescent bulb so he build his own LED replacement. If you recognize his name it’s because we saw a beautifully crafted in-visor GPS system that he built back in April. This project exhibits the same level of craftsmanship in which he utilized the base of a spare bulb to add an LED, heat sink, and driver board that is adjustable on all three axes.

He also mentioned that he overhauled his site design and it now plays nicely with all browsers.

Microscope camera adapter

[Ben Krasnow] is capturing some great snapshots using a microscope adapter and some tricks. The camera attachment is just a lens adapter ring with a tube added. Unlike other microscope imaging hacks we’ve seen he used a real microscope but found that the pictures had a bit of light distortion to them. The camera sensor was picking up a glare reflected on the inside of the black tube. By adding a washer and repositioning the apparatus he got over that hurdle. The final part of the puzzle is image processing. By taking several pictures at different focal lengths and compositing them he gets killer photos like the compound eyes of that house fly seen above.

Open Source STM

We hope you paid attention in advanced theoretical and quantum physics classes, or making your own Open Source Scanning-Tunneling Microscope might be a bit of a doozy. We’re not even going to try to begin to explain the device (honestly we slept through that course) beyond clarifying it is used for examining the molecular and atomic structure of surfaces; but for those still interested there is a nice breakdown of how Scanning Tunneling Microscopy works.

Microscope lens hack

Who doesn’t need to take pictures of the microscopic bits inside of an integrated circuit? [Mojobojo] made an end-run around the expensive equipment by building a microscopic lens from an old camcorder. He’s using a regular digital camera with the lens set to its largest zoom level. The camera is pointed into the salvaged camcorder lens where the fine tuning is done. His first iteration was just taped to the desk with a small hand flashlight illuminating the subject. He upgraded that setup by building a LEGO enclosure and changing to a much brighter light source. The images he’s getting are quite surprising and this will be very useful during those extreme hacks when you need to tap into an IC’s internal data rails.

Hard Core Nintendo DSI hacking

dsi (Custom)

So, you hacked your DSI did you? Let me guess, you ran a flash cart. No? You probably added some LEDs then right? No? You must be pretty hard core, did you add a NES controler? No? Well what did you do?

We still have no idea what this guy is doing. But he is doing it very meticulously. We found [Micah Dowty]‘s photo stream on flicker and we were instantly pulled in. He has done some extensive modifications to his DSI. He has spread its innards for all to see and begun hacking. It appears as though most of this is for memory dumps and direct access to the RAM in the unit, but frankly we just want to stare at these pictures.

Flip camera microscope and macro lenses


Flip cameras are fun and easy to use, but not particularly versatile. If you’ve had poor results at macrophotography with a Flip, you might be interested in these DIY lenses. One is macroscopic lens for taking photos and video of small things, and the other is a microscope for even smaller things.

To construct the macro lens, you’ll need a pair of binoculars, some rubber bands and paper clips. Simply remove the lenses from the front of the binoculars, complete with the plastic casings that hold them. Thread a rubber band folded in half to the plastic casing and hold it in place with small segments from the paper clip. Now place the lens in front of the Flip’s lens and secure the rubber band around the flip.

The microscope’s eyepiece uses no such attachment method, simply hold it in front of the Flip. The same process can’t be used here because getting the proper focus requires it to be held at varying distances from the camera, not flush against it like the macro lens. In any case, it’s any easy mod that should have you taking pictures of bugs and other tiny things in no time. Look after the break for video of the lenses in action.
