As anyone who extrudes plastic noodles knows, the glass transition temperature of a material is a bit misleading; polymers gradually transition between a glass and a liquid across a range …read more Continue reading A New and Strangely Strong Kind of Plastic
Like many of us, [Tim]’s seen online videos of circuit sculptures containing illuminated LED filaments. Unlike most of us, however, he went a step further by using graph theory to …read more Continue reading The Graph Theory of Circuit Sculptures
Hackers have been building their own basic oscilloscopes out of inexpensive MCUs and cheap LCD screens for some years now, but microcontrollers have recently become fast enough to actually make …read more Continue reading A Higher-End Pico-Based Oscilloscope
We’ve been following [Vik Olliver]’s progress on the μRepRap project with interest for some time now. The project’s goal is to build a 3D printer that can print feature sizes …read more Continue reading The Latest from RepRapMicron – Nail Gel, First Objects, and More

The development of cheaper, more powerful lasers has always been a cause for excitement among hackers, and fiber lasers are no exception. One of the newer tools they’ve enabled is …read more Continue reading Building a Metal 3D Printer with a Laser Welder
Dy default, the slicing software used for 3D printers has the printer first create the walls around the edges of a print, then goes back to deposit the infill pattern. …read more Continue reading Changing Print Layer Patterns to Increase Strength
When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam …read more Continue reading Why Diffraction Gratings Create Fourier Transforms
Setting up access to a headless Raspberry Pi is one of those tasks that should take a few minutes, but for some reason always seems to take much longer. The …read more Continue reading SSH over USB on a Raspberry Pi
For certain high-security devices, such as card readers, ATMs, and hardware security modules, normal physical security isn’t enough – they need to wipe out their sensitive data if someone starts …read more Continue reading Tamper Detection with Time-Domain Reflectometry
