Update time! The CoreXY Laser Engraver has been updated with a motorized Z axis and numerous other enhancements… like more laser power. Har Har Har!
When Jogi posted his make on Thingiverse he already added many improvements over my initial design, like cable chains, larger build area and overall cleanliness (I’ll address this one in Mk3 😉 ). We started discussing about a Z axis and it got me hooked up right away. Here’s the result!
Another simple 3D print: keep your loose wire spools organized and ready for dispensing.
Lasers are fun, especially high-power ones. Some time ago I purchased a 1 W blue laser and due to a recent 3D printer upgrade I had some spare linear motion components. The next steps are quite obvious, build a 2D laser engraver! I’ve always liked the CoreXY kinematic design and chose to use it in this project.
Same old story, I was creating a simple temperature sensor and could not find a proper case. So, 3D printer to the rescue! 😉
Many electronics projects need some kind of user input. For those where you need scrolling functionality, in a menu for example, or enter numerical values like a timeout, rotary encoders are very convenient. They are cheap, easy to use and require minimal to none additional components. However, interfacing them requires little more work on the software side than with regular buttons. In this tutorial I present everything needed to use a rotary encoder with a microcontroller. While I used an ATmega uC it should be easily portable to other platforms
In this small tutorial I will show you how to start programming Atmel microcontrollers under GNU/Linux, Debian in particular. It covers all steps starting with the software prerequisites, setting up a minimal circuit to actually flashing the microcontroller with the obligatory “Hello, World!” program. There are a few stumbling blocks that I hit along the way and I will explicitly point them out and show what to do about them. Hopefully this will save you some frustration.
If you like experimenting with electronics sooner or later you’ll want to create an etched PCB with your own circuit. For testing purposes there’s of course the breadboard and simple circuits can be easily built on a stripboard but as soon as the complexity grows designing layouts in some electronics software is the natural way to go.
