The new Smart Cutting Machine brings industrial-level control, real-time feedback, and maker-focused engineering to lapidary and metal cutting. For decades, makers have faced a difficult choice when it comes to precision cutting. Entry-level desktop saws are accessible, but often require users to compromise on control, visibility and consistency.

Whoop There It Is! To start this project off, we’ll remove the motor connectors on the Matrix flight controller to cut weight. The easiest way is to carefully clamp the controller into a hobby vise so that it sits level in the jaws, with its motor connectors on the bottom. Alternatively you can use helping hands, but take care to attach the clamps where they won’t damage any of the SMD components.

To upload new firmware and files to LittleFS file system see randomnerdtutorials.com/esp32-ota-elegantota-arduino/ For uploading firmware, ElegantOTA works just like a serial cable – specify the file to upload, it’s loaded into the module’s program space. To create the firmware file, select ‘Sketch’, then ‘Export Compiled Binary’ in the Arduino IDE. This will create a file named “<sketchname>.ino.bootloader.bin” in your user folder (C:\users\<username>\temp).

Earth’s atmospheric “sunscreen” is vital to life. Find its peak altitude with this DIY instrument. Using Your Ozone Photometer Processing the Data How to Install Surface-Mount Components Cleanliness and a dust-free room are essential when assembling an ultra-high-gain twilight photometer. While holding the circuit board by its edges with clean hands, thoroughly wipe both sides with a clean paper towel soaked in isopropyl alcohol. Allow the alcohol to stay on the board for a few minutes.

Featured image: Laura Mathews shows off her big mechanical wings. Open Sauce, the engineering YouTube convention inspired by Maker Faire, once again invited makers to fill the San Mateo County Event Center with wacky projects for people to be impressed by. This was the second year the event was in San Mateo, and there were more exhibits filling up more rooms than before.

HeyGears has officially launched the G1 Series on Kickstarter. The world’s first desktop full-color 3D & UV printer, the G1 Series combines full-color 3D printing, 3D-textured UV printing, and 2D UV printing in one modular system. Designed for creators, artists, customization businesses, and small production studios, the G1 Series helps users turn digital ideas into colorful, ready-to-use products with less manual finishing.

In this Make: Live session, join Dale Dougherty and authors Joan Horvath and Rich Cameron for an in-depth look at Make: Physics, their new physics book bringing a learn-by-doing approach to mechanics for advanced high schoolers, first-year college engineering students, and adults who want to reengage with the world of science. Joan and Rich have spent over a decade teaching educators and scientists how to use maker tech.

Onshape offers a free, hobby and education use license for full functionality of their program on the cloud, with the exception that all projects made on the free plan are public and searchable. This means that derivatives of these designs will also be available to the public. To modify a design, you’ll need to create an Onshape account and duplicate/copy a new version to make changes. Most CNC users will likely want to export all of the parts as DXFs. This is a very easy process.

Manufacturer: Seeed Studio Price as tested: $79 Link: arduboy.com Arduboy, the credit card-sized game console, keeps evolving, now with the FX-C. It’s still pocket sized and still powered by an 8-bit ATMega32u4. Though the power is tiny compared to the ubiquitous ESP32, it still sports a library of 300 community-made games and counting. It’s small and light enough that I forgot I was carrying it around, and the monochromatic screen is bright enough to play outside. An RGB LED adds a hint of color.

The Open Source Hardware Association (OSHWA) runs a free program that allows creators to certify that their hardware complies with the community definition of open source hardware. Whenever you see the certification logo, you know that the certified hardware meets this standard. Currently the Certification database lists 3352 individual certifications! In June we added 26 new certifications, from microcontrollers to scrolling tools and everything in between.
