One of the essentials on the bench is some form of hot air gun. Whether it’s a precision tool intended for reworking PCBs or the broad-stroke item used for paint stripping, we’ve all got one somewhere. The paint-stripping variety are pretty cheap, but not as cheap as [Porcas Pregos e Parafusos]’s home made hot air gun.

Older industrial equipment is often a great option if you’re on a budget, and you might even be able to add some premium features yourself. [Brett] from [Theoretically Practical] has done with his old MIG welder, adding premium control features with the help of an Arduino. The main features [Brett] were after is pre-flow, post-flow, and

One of the selling points of the Arduboy is how slim [Kevin Bates] was able to get the Arduino-compatible game system, which is perhaps less surprising when you realize that it originally started out as a design for an electronic business card. But compared to the recently unveiled Nano version, it might as well be the

Considering the state of well, everything, we can’t tell you how glad we are to be out of school. That goes double for not being a teacher these days. [Elena] had some awesome light-up tactile buttons set aside for a killer Kerbal Space Program controller, but it’s funny how a pandemic will change your priorities. Instead,

We’ve all likely seen the amazing images possible with a scanning electron microscope. An SEM can yield remarkably detailed 3D images of the tiniest structures, and they can be invaluable tools for research. But blasting high-energy cathode rays onto metal-coated samples in the vacuum chamber of a bulky and expensive instrument isn’t the only way

Call us easily amused, but we think it’s pretty amazing what can be done with a microcontroller, some RGB LEDs, and a little bit of plastic. Case in point is [andrei.erdei]’s beautiful and quite approachable fiber optic LED lamp. It’s a desktop-friendly version of a similar piece [andrei] made that is roughly nine times the size

SRKH Designs has designed and created a new processor module in the form of the microZERO SAMD CPU board that is compatible with Arduino development boards and could be the perfect processor for your next project. The ultra low power networked microZERO module has been inspired by the MKR Zero, and offers a a small,

Makers, developers and electronic enthusiasts looking for a way to add a digital smell detector, sensor and nose to their project may be interested in a new piece of hardware called the Smell Inspector, designed by SmartNanotubes Technologies based in Germany. The Smell Inspector takes the form of a developers kit and ready to use electronic

Just when you think you’ve seen every possible way to play the piano, [Alessandro Perini] came up with a new one. In this piece, written for the percussionist [Irene Bianco], hand-held motors become a tangible interface between composer, electronic music equipment, and the performer. The performance involved ten small disc motors, held above the strings by

For some, the idea of several hours of painting and designing intricate models with minute details and features sounds like a delightful afternoon spent. Some of us would much rather just have it come already painted with motors so that it can move. [Cory Collins] sought to combine these two hobbies by building a highly detailed
