Sometimes I need to be able to take photographs of very small things, and the so-called macro mode on my point-and-shoot camera just won’t cut it. And it never hurts to have an inspection scope on hand for tiny soldering jobs, either, though I prefer a simple jeweler’s loupe in one eye for most tasks. So I sent just over $40 off to my close friend Alibaba, and a few weeks later was the proud owner of a halfway usable inspection scope that records stills or video to an SD card.
Unfortunately, it’s only halfway useable because of chintzy interface design and a wobbly mount. So I spent an afternoon, took the microscope apart, and got it under microcontroller control, complete with WiFi and a scripting language. Much better! Now I can make microscope time-lapses, but much more importantly I can take blur-free photos without touching the wiggly rig. It was a fun hack, so I thought I’d share. Read on!

When the [Director of Legal Evil] at Louisville’s LVL1 Hackerspace decided to demonstrate the uselessness of a 3D printer by printing a fidget spinner, another member at the space’s Tuesday meeting rose to the challenge and built a machine that whose sole purpose is to spin fidget spinners.
[Gary Flispart] used an Arduino clone and what appears to be a motor driver in conjunction with a stepper motor. The motor moves a belt that turns a series of metal scraps serving as a four-bar linkage. The linkage moves the dowel that turns the spinner and then gets out of the way so it doesn’t inhibit the toy’s rotation. The Digital Fidget Digit, as [Gary] calls it, looks like it was built out of scrap metal and random pieces of wood in the glorious tradition of hackerspace projects.
We at Hackaday love crazy projects that come out of hackerspaces, like the iris porthole at i3Detroit, another space’s ultimate fume extractor, and LVL1’s doomcano.

Infinity mirrors are some far-out table mods and make a great centerpiece. Instructables user [bongoboy23] took a couple steps beyond infinity when designing this incredible table tailor-made for our modern age.
Poplar and pine wood make up the framing, and red oak — stained and engraved — make for a chic exterior. Programmed with Arduino and run on a Teensy 3.1, the tabletop has 960 LEDs in forty sections. There are, four USB ports hidden behind sliding panels, as well as a two-port AC outlet and an inductive charging pad and circuit. A hidden Adafruit TFT touchscreen display allows the user to control the table’s functions. Control is limited to changing lighting functions, but Pac-Man, Snake, and text features are still to come!
Weighing in at $850, it’s not a cheap build, but it looks amazing.
