Modern electronic experimenter kits contain modules that just plug together rather than individual components so that now we can quickly get modules talking and then decide in software how the system behaves. Thanks to the wide selection of software library functions we can have a sketch up and running in no time. These kits are worthy successors to the bags of loose components that were a feature of earlier experimenter’s kits. Electronic newbies, practicing engineers and old hands alike are sure to find that these kits interesting. The range of components is sure to get you thinking what you could use them for and they are a good way to build on your existing knowledge. You’ll have no excuse not to go on to design and build your own system! The ‘RFID Starter Kit for Arduino’ comes in a handy case and contains over 30 state-of-the-art components, devices and modules. Although it contains an RFID receiver module along with two RFID tags in the form of a credit card and key fob, the case is an Aladdin’s cave with loads of other useful components. To begin you will need an Arduino Uno along with the starter kit which amongst other things contains: A humidity sensor; A multicolor LED; A large LED-Matrix with 64 LEDs; 4 x 7-segment LED displays; A handheld IR remote controller plus IR receiver chip; A complete LC-Display module with I²C bus interface. The wide range of peripherals included in the kit ensures the number of different experiments and applications you can build. Two example applications that can easily be built using this box of goodies have been described in an article published in Elektor Magazine: Universal weather station with LC-Display and Door entry system using RFID security. More similar projects have been described in the new book Home Automation Projects with Arduino.

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.

With the availability of free and open source C/C++ compilers today, you might wonder why someone would be interested in assembler language. What is so compelling about the RISC-V Instruction Set Architecture (ISA)? How does RISC-V differ from existing architectures? And most importantly, how do we gain experience with the RISC-V without a major investment? Is there affordable hardware available?
The availability of the Espressif ESP32-C3 chip provides a way to get hands-on experience with RISC-V. The open sourced QEMU emulator adds a 64-bit experience in RISC-V under Linux. These are just two ways for the student and enthusiast alike to explore RISC-V in this book.
The projects in this book are boiled down to the barest essentials to keep the assembly language concepts clear and simple. In this manner you will have “aha!” moments rather than puzzling about something difficult. The focus in this book is about learning how to write RISC-V assembly language code without getting bogged down. As you work your way through this tutorial, you’ll build up small demonstration programs to be run and tested. Often the result is some simple printed messages to prove a concept. Once you’ve mastered these basic concepts, you will be well equipped to apply assembly language in larger projects.

This filter rejects signals between 88-108 MHz with around 50 dB or more attenuation. A broadcast FM band-stop filter is very useful for use with SDRs as in some areas broadcast FM signals can be so strong that they overload the SDR, causing very poor performance in other bands. You can tell if this is the case for you if you see images of BCFM stations or interference that looks like a WFM signal at other frequencies when you turn up the gain.
The filter is based on a simple 7th order Chebyshev design. The 3 dB roll off is at 76 MHz and 122 MHz. 88 MHz is attenuated by almost 60 dB, and 108 MHz is attenuated by 45-50 dB. Outside of the pass band the insertion loss is practically zero below 500 MHz, less than 0.5 dB from 500 MHz – 1 GHz, and below 1.5 dB between 1-2 GHz. Between 2-3 GHz performance degrades slightly, but insertion loss remains below 1.5 dB for most frequencies. The filter can also pass up to 80 mA of DC current (probably can do more) and has negligible DC resistance.
The filter comes in a 28 x 28 x 13 mm aluminum enclosure and uses female SMA connectors on each end. Included in the package is also a SMA male to SMA male straight barrel adapter.
RTL-SDR is an affordable dongle that can be used as a computer-based radio scanner for receiving live radio signals between 500 kHz and 1.75 GHz in your area.
The RTL-SDR V4 offers several improvements over generic brands including use of the R828D tuner chip, triplexed input filter, notch filter, improved component tolerances, a 1 PPM temperature compensated oscillator (TCXO), SMA F connector, aluminium case with passive cooling, bias tee circuit, improved power supply, and a built in HF upconverter.
RTL-SDR V4 comes with the portable dipole antenna kit. It is great for beginners as it allows for terrestrial and satellite reception and easy to mount outdoors and designed for portable and temporary outside usage.
Features
Improved HF reception: V4 now uses a built-in upconverter instead of using a direct sampling circuit. This means no more Nyquist folding of signals around 14.4 MHz, improved sensitivity, and adjustable gain on HF. Like the V3, the lower tuning range remains at 500 kHz and very strong reception may still require front end attenuation/filtering.
Improved filtering: The V4 makes use of the R828D tuner chip, which has three inputs. The SMA input has been triplexed input into 3 bands: HF, VHF and UHF. This provides some isolation between the 3 bands, meaning out of band interference from strong broadcast stations is less likely to cause desensitization or imaging.
Improved filtering x2: In addition to the triplexing, the open drain pin on the R828D can be also used, which allows to add simple notch filters for common interference bands such as broadcast AM, broadcast FM and the DAB bands. These only attenuate by a few dB, but may still help.
Improved phase noise on strong signals: Due to an improved power supply design, phase noise from power supply noise has been significantly reduced.
Less heat: Another advantage of the improved power supply is low power consumption and less heat generation compared to the V3.
Included
1x RTL-SDR V4 dongle (R828D RTL2832U 1PPM TCXO SMA)
2x 23 cm to 1 m telescopic antenna

The short-wave technique has a very particular appeal: It can easily bridge long distances. By reflecting short-wave signals off the conductive layers of the ionosphere, they can be received in places beyond the horizon and therefore can reach anywhere on earth. Although technology is striving for ever higher frequencies, and radio is usually listened to on FM, DAB+, satellite or the Internet, modern means of transmission require extensive infrastructure and are extremely vulnerable. In the event of a global power outage, there is nothing more important than the short-wave. Amateur radio is not only a hobby, it’s also an emergency radio system!
Elektor’s SDR-Shield is a versatile shortwave receiver up to 30 MHz. Using an Arduino and the appropriate software, radio stations, morse signals, SSB stations, and digital signals can be received.
In this book, successful author and enthusiastic radio amateur, Burkhard Kainka describes the modern practice of software defined radio using the Elektor SDR Shield. He not only imparts a theoretical background but also explains numerous open source software tools.
