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

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.

PiKVM: Raspberry Pi as a KVM Remote Control
Programming the Finite State Machine with 8-Bit PICs in Assembly and C
Andrew Pratt provides a detailed introduction to programming PIC microcontrollers, as well as a thorough overview of the Finite State Machine (FSM) approach to programming. Most of the book uses assembly programming, but do not be deterred. The FSM gives a structure to a program, making it easy to plan, write, and modify. The last two chapters introduce programming in C, so you can make a direct comparison between the two techniques. The book references the relevant parts of the Microchip datasheet as familiarity with it is the best way to discover detailed information.
This book is aimed at Microsoft Windows and Linux users. To keep your costs to a minimum and to simplify the toolchain, specific applications are provided as a free download to enable you to use an FTDI serial lead as the programmer. The assembler used is the open-source "gpasm". All programming can be done in a text editor. There are detailed instructions on how to perform the necessary installations on Windows, Linux Debian, and derivatives such as Ubuntu and Fedora. For programming in C, Microchip's XC8 compiler is used from the command line. In addition to the programming applications, two serial read and serial write applications can be used for communicating with the PICs from a computer.
A voltmeter project including practical instructions on building a circuit board from scratch is included. All theory is covered beforehand, including how to do integer arithmetic in assembly.
Two PICs are covered: the PIC12F1822 and the PIC16F1823. Both can run at 32 MHz with an internal oscillator. You do not need to buy a factory-made development board and programmer. With relatively inexpensive parts including a serial lead, microcontroller, a few resistors, and LEDs, you can get started exploring embedded programming.

Updated Programmer
Most people are increasingly confronted with the applications of Artificial Intelligence (AI). Music or video ratings, navigation systems, shopping advice, etc. are based on methods that can be attributed to this field.
The term Artificial Intelligence was coined in 1956 at an international conference known as the Dartmouth Summer Research Project. One basic approach was to model the functioning of the human brain and to construct advanced computer systems based on this. Soon it should be clear how the human mind works. Transferring it to a machine was considered only a small step. This notion proved to be a bit too optimistic. Nevertheless, the progress of modern AI, or rather its subspecialty called Machine Learning (ML), can no longer be denied.
In this book, several different systems will be used to get to know the methods of machine learning in more detail. In addition to the PC, both the Raspberry Pi and the Maixduino will demonstrate their capabilities in the individual projects. In addition to applications such as object and facial recognition, practical systems such as bottle detectors, person counters, or a “talking eye” will also be created.
The latter is capable of acoustically describing objects or faces that are detected automatically. For example, if a vehicle is in the field of view of the connected camera, the information 'I see a car!' is output via electronically generated speech. Such devices are highly interesting examples of how, for example, blind or severely visually impaired people can also benefit from AI systems.
Plot, Cut, Drill, Mill and Laser with the Z99
This book covers the construction, hardware, software, and operation of the Z99 – CNC machine. This is a multifunctional 4-axis machine for home construction.
The capabilities of the Z99 machine include:
large-format schematic plotting
PCB plotting with etch-resist pens
schematic plotting with conductive-ink pens
letter cutting out of vinyl
paper cutting
PCB/substrate drilling
PCB/substrate milling
text milling
laser engraving
laser cutting of solder paste masks
By making the support software available as freeware, readers of the book are challenged and encouraged to develop new applications for the Z99.
The machine would not be of much use if the user has no option to create suitable files for the designs in mind. A large part of this book is dedicated to creating source files in a variety of freeware software packages, including Inkscape, DesignSpark PCB, KiCad, and FlatCAM.
The book is also useful for readers keen to comprehend and then master the basic structure of HPGL, Gerber, Drill, and G-code files, as well as to have a go at deciphering them using software.
The flexibility of the Artemis module starts with SparkFun's Arduino core. You can program and use the Artemis module just like you would an Uno or any other Arduino. The time to first blink is just 5 minutes away! We built the core from the ground up, making it fast and as lightweight as possible.
Next is the module itself. Measuring 10 x 15 mm, the Artemis module has all the support circuitry you need to use the fantastic Ambiq Apollo3 processor in your next project. We're proud to say the SparkFun Artemis module is the first open-source hardware module with the design files freely and easily available. We've carefully designed the module so that implementing Artemis into your design can be done with low-cost 2-layer PCBs and 8mil trace/space.
Made in the USA at SparkFun's Boulder production line, the Artemis module is designed for consumer-grade products. This truly differentiates the Artemis from its Arduino brethren. Ready to scale your product? The Artemis will grow with you beyond the Uno footprint and Arduino IDE. Additionally, the Artemis has an advanced HAL (hardware abstraction layer), allowing users to push the modern Cortex-M4F architecture to its limit.
The SparkFun Artemis Module is fully FCC/IC/CE certified and is available in full tape and reel quantities. With 1M flash and 384k RAM, you'll have plenty of room for your code. The Artemis module runs at 48MHz with a 96MHz turbo mode available and with Bluetooth to boot!
Voice recognition, always-on voice commands, gesture, or image recognition are possible with TensorFlow applications. The cloud is impressively robust, but all-the-time connection requires power and connectivity that may not be available. Edge computing handles discrete tasks such as determining if someone said 'yes' and responds accordingly. The audio analysis is done on the MicroMod combination rather than on the web. This dramatically reduces costs and complexity while limiting potential data privacy leaks.
This board features two MEMS microphones (one with a PDM interface, one with an I²S interface), an ST LIS2DH12 3-axis accelerometer, a connector to interface to a camera (sold separately), and a Qwiic connector. A modern USB-C connector makes programming easy and we've exposed the JTAG connector for more advanced users who prefer to use the power and speed of professional tools. We've even added a convenient jumper to measure current consumption for low power testing.
