Elektor Labs Elektor Sand Clock for Raspberry Pi Pico (incl. Laser Head Upgrade)
This bundle contains the popular Elektor Sand Clock for Raspberry Pi Pico and the new Elektor Laser Head Upgrade, offering even more options for displaying the time. Not only can you "engrave" the current time in sand, you can now alternatively write it on a glow-in-the-dark foil or create green drawings. Contents of the bundle Elektor Sand Clock for Raspberry Pi Pico (normal price: €50) Elektor Laser Head Upgrade for Sand Clock (normal price: €35) Elektor Sand Clock for Raspberry Pi (Raspberry Pi-based Eye Catcher) A standard sand clock just shows how time passes. In contrast, this Raspberry Pi Pico-controlled sand clock shows the exact time by "engraving" the four digits for hour and minute into the layer of sand. After an adjustable time the sand is flattened out by two vibration motors and everything begins all over again. At the heart of the sand clock are two servo motors driving a writing pen through a pantograph mechanism. A third servo motor lifts the pen up and down. The sand container is equipped with two vibration motors to flatten the sand. The electronic part of the sand clock consists of a Raspberry Pi Pico and an RTC/driver board with a real-time clock, plus driver circuits for the servo motors. A detailed construction manual is available for downloading. Features Dimensions: 135 x 110 x 80 mm Build time: approx. 1.5 to 2 hours Included 3x Precut acrylic sheets with all mechanical parts 3x Mini servo motors 2x Vibration motors 1x Raspberry Pi Pico 1x RTC/driver board with assembled parts Nuts, bolts, spacers, and wires for the assembly Fine-grained white sand Elektor Laser Head Upgrade for Sand Clock The new Elektor Laser Head transforms the Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam! The kit includes all the necessary components, but soldering three wires is required. Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.

Elektor Bundles Raspberry Pi 5 RTL-SDR V4 (Bundle)
Program and build Raspberry Pi based ham station utilities, tools, and instruments The improved RTL-SDR V4 allows you to receive radio signals between 500 kHz and 1.75 GHz from stations utilizing different bands including MW/SW/LW broadcast, ham radio, utility, air traffic control, PMR, SRD, ISM, CB, weather satellite, and radio astronomy. The book Raspberry Pi 5 for Radio Amateurs gives extensive coverage of deploying the RTL-SDR kit through the use of a Raspberry Pi 5. This bundle contains: RTL-SDR V4 (incl. Dipole Antenna Kit) (normal price: €75) Raspberry Pi 5 for Radio Amateurs (normal price: €40) RTL-SDR V4 (Software Defined Radio) with Dipole Antenna Kit 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 2x 5 cm to 13 cm telescopic antenna 1x Dipole antenna base with 60 cm RG174 1x 3 m RG174 extension cable 1x Flexible tripod mount 1x Suction cup mount Downloads Datasheet User Guide Quick Start Guide SDR# User Guide Dipole Antenna Guide Book: Raspberry Pi 5 for Radio Amateurs The RTL-SDR devices (V3 and V4) have gained popularity among radio amateurs because of their very low cost and rich features. A basic system may consist of a USB based RTL-SDR device (dongle) with a suitable antenna, a Raspberry Pi 5 computer, a USB based external audio input-output adapter, and software installed on the Raspberry Pi 5 computer. With such a modest setup, it is possible to receive signals from around 24 MHz to over 1.7 GHz. This book is aimed at amateur radio enthusiasts and electronic engineering students, as well as at anyone interested in learning to use the Raspberry Pi 5 to build electronic projects. The book is suitable for both beginners through experienced readers. Some knowledge of the Python programming language is required to understand and eventually modify the projects given in the book. A block diagram, a circuit diagram, and a complete Python program listing is given for each project, alongside a comprehensive description. The following popular RTL-SDR programs are discussed in detail, aided by step-by-step installation guides for practical use on a Raspberry Pi 5: SimpleFM GQRX SDR++ CubicSDR RTL-SDR Server Dump1090 FLDIGI Quick RTL_433 aldo xcwcp GPredict TWCLOCK CQRLOG klog Morse2Ascii PyQSO Welle.io Ham Clock CHIRP xastir qsstv flrig XyGrib FreeDV Qtel (EchoLink) XDX (DX-Cluster) WSJT-X The application of the Python programming language on the latest Raspberry Pi 5 platform precludes the use of the programs in the book from working on older versions of Raspberry Pi computers.
