This may be one of the cheapest and easiest CNC drawing machines you’ll find
https://blog.arduino.cc/2021/07/15/this-may-be-one-of-the-cheapest-and-easiest-cnc-drawing-machines-youll-find/
CNC plotters are a lot of fun to build and use, as they teach mechanics, electronics, and how G-code works. However, traditional Cartesian machines often require expensive components such as linear rods and ample amounts of bearings to move in just two axes. YouTuber DAZ Projects set out to change that by assembling a form of a Polargraph to draw pictures with great detail. The idea is simple: use a pair of stepper motors to alter the length of a string on two sides that controls where the toolhead goes.
He started by 3D printing stepper motor mounts, a few pulleys for the string to wrap around, and the pen holding/lifting mechanism. Both 5V stepper motors plug into a generic Grbl CNC shield and are driven by a couple of A4988 modules. The servo is powered directly by an Arduino Uno, and its job is to adjust the pressure the pen applies to the page to define how dark the lines are.

This light painting machine puts a new spin on the old geometric chuck
https://blog.arduino.cc/2021/07/19/this-light-painting-machine-puts-a-modern-spin-on-the-old-geometric-chuck/
Light painting is a fun way to create digital images by using just a few points of light to “draw” across a camera with a long exposure time. This gives the illusion of a virtual streamer being dragged on the canvas and can produce amazing photos. Ted Kinsman wanted to build a light painting machine, which mimics the geometric chucks from the 1860s that used several spinning platters on a lathe that rotated at different speeds to carve ornate patterns into wood. His version has a series of three platters all stacked on top of each other and are driven by three stepper motors.

How to automatic plant watering system

Today we are making something that is not only interesting but also very useful in our day-to-day busy schedule of us. So today we are going to describe How to make an automatic plant watering system, out of Arduino and few other small sensors and other stuff, and have a look at how it works. It is very useful in Northern areas because due to less sunlight and high humidity it is very hard to grow plants.

CLEVER PCB BRINGS MICRO USB TO THE ARDUINO UNO
https://hackaday.com/2021/07/21/clever-pcb-brings-micro-usb-to-the-arduino-uno/
Even with more and more devices making the leap to USB-C, the Arduino Uno still proudly sports a comparatively ancient Type-B port. It wouldn’t be a stretch to say that many Hackaday readers only keep one of these cables around because they’ve still got an Uno or two they need to plug in occasionally.
Looking to at least move things in the right direction, [sjm4306] recently set out to create a simple board that would let him mount a micro USB connector in place of the Uno’s original Type-B. Naturally there are no components on the PCB, it simply adapts the original through-hole footprint to the tight grouping of surface mount pads necessary to mount a female micro USB port.

This massive five-axis CNC machine is 3D-printable
https://blog.arduino.cc/2021/08/04/this-massive-five-axis-cnc-machine-is-3d-printable/
CNC (Computer Numerical Control) mills, routers, and lathes are indispensable manufacturing tools. If you need a part that adheres to tight tolerances, you turn to a CNC machine. Industrial CNC equipment is usually large, heavy, and very expensive. But small models exist for light-duty hobby jobs. This DIY version designed by Brian Brocken stands out because it is huge, has five axes, and is 3D-printable.
