Extra easel boards for AxiDraw V3/A3 can be used as replacements, or for staging additional workpieces for quickly swapping to the next plot. This set consists of one 11.75 x 17 inch (29.85 x 43.18 cm) hardboard platen with rubber feet attached, plus eight micro binder clips.
The tripod adapter is custom machined from a solid block of aluminum, and provides two standard tripod mounting points with 3/8-16 and light-duty 1/4-20 thread respectively. This allows you to mount the AxiDraw to a tripod, should you have reason to do so.
We would highly recommend using a sturdy tripod with a 3/8-16 connection point and appropriate counterweight (sand bag, lifting weights, etc) to balance the weight of the AxiDraw while in use.
Installation is straightforward, and does not require any tools other than those included with AxiDraw: Remove the existing foot pads from the AxiDraw (either standard or outrigger feet, depending on model) and attach this plate to the captured nuts in the bottom surface of the AxiDraw. For AxiDraw SE/A3 (April 2019 and newer), the tripod adapter attaches directly to tapped holes in the base of the machine.
This heavy-duty tripod adapter is compatible with AxiDraw V3, AxiDraw V3/A3 and AxiDraw V3 XLX. It is also compatible with AxiDraw SE/A3 manufactured in April 2019 and newer.
Specifications
Material: Anodized 6061-T6 aluminum
Size: 3.90 x 2.36 x 0.35 inches (99.1 x 60 x 8.3 mm)
Weight: Approximately 144 g
Mounting hardware: included (four M4x10 high-strength steel mounting screws)
This rigid end effector plate is designed to be in place of the standard AxiDraw pen-lift Z stage, and provides an alternative mounting scheme for mounting various things to the end of the AxiDraw's arm, for applications where greater rigidity is important but the lifting ability of the standard Z stage is not required.
The rigid end effector is custom machined from aluminum, and provides six M3 tapped holes and two M4 tapped holes for mounting what ever it is that you would like to mount to the end of the AxiDraw, to use it as a 2D robot arm. The hole pattern is compatible with the AxiDraw pen clip, so you can, if you like, mount the AxiDraw's pen clip to this end effector.
Installation is straightforward, but requires a Pozidrive PZ2 screwdriver, not included*. Remove the AxiDraw's pen clip, and then remove the pen-lift Z stage by removing two screws with the PZ2 screwdriver. Install the rigid end effector plate in its place, using the two included mounting screws and the PZ2 screwdriver. You may wish to also tie back or fully remove the AxiDraw's cable guides, which normally extend to power the pen-lift stage.

Space, the final frontier, will become more and more popular. The space industry is continually growing and new products and services will be required. Innovation is needed for the development of this industry. Today it is no longer possible to follow all the events in field of space. The space market is growing and activities are increasing, especially the market for small-satellites.
This book wants to help close the gap and encourage electronic engineers to enter into the fascinating field of space electronics. One of the main difficulties is finding people with knowledge of space electronics design. Nowadays companies have to invest a lot of time and resources to instruct electronic engineers with no experience of space. Only a brief and basic introduction of this topic is typically achieved at university in space engineering lectures. Professionals with practical experience and the necessary theoretical knowledge are scarce. Companies from the space sector are searching for staff with knowledge of space electronics.
This book will bring space closer aspiring to the space electronic hobbyists.

Practical Introduction to 3D Modeling from Enclosure to Front Panel
Embedding a vintage component, creating a professional looking home for a circuit board, or even designing a complex apparatus complete with a chassis – these and many other challenges turn into a stimulating pleasure with FreeCAD. Once you have internalized the basic processes, there are virtually no limits to your imagination.
Starting to use a new software is never straightforward – especially with a tool as versatile as FreeCAD. Manageable, but at the same time easily usable individual components provide the starting point in this book. Putting these components together later results in assemblies.
In the FreeCAD universe, a workable trajectory is demonstrated. The described procedure is illustrative so the examples are easily applied to custom tasks. The devices were made by the author and illustrated with photos.
Creating a 3D design is requiring some effort but the initial investment pays off soon. Besides the impressive spatial representation of the projects, the extracted drawings yield a solid base for documentation and production. Extended FreeCAD capabilities like the unfolding of sheet metal parts enormously add to efficiency and pushes models forward into practical assembly.
Soon you will definitely not want to do without FreeCAD!
Analogue Electronics and Microcontrollers Projects
Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk.
It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience.
Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It’s now a case of less soldering and more programming.
