Elektor Labs Sand Clock Kit (based on Raspberry Pi Pico)
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: 1.5 to 2 hours approx. 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

Witty Pi 4 - Real-time Clock and Power Management for Raspberry Pi
Witty Pi is an add-on board that adds realtime clock and power management to your Raspberry Pi. It can define your Raspberry Pi’s ON/OFF sequence, and significantly reduce the energy usage. Witty Pi 4 is the fourth generation of Witty Pi and it has these hardware resources onboard: Factory calibrated and temperature compensated realtime clock with ±2 ppm accuracy. Dedicated temperature sensor with 0.125 °C resolution. On-board DC/DC converter that accepts up to 30 V DC. AVR 8-bit microcontroller (MCU) with 8 KB programmable flash. Accurate realtime clock and ON/OFF scheduling The realtime clock (RTC) on Witty Pi 4 has been calibrated in the factory and Witty Pi 4’s firmware also makes temperature compensation for the crystal. This makes the RTC very accurate and the actual annual error is limited within ±2 ppm. When your Raspberry Pi boots up, the time stored in the RTC will overwrite the system time. As a result, your Raspberry Pi knows the correct time even without accessing the Internet. You can schedule the startup and/or shutdown of your Raspberry Pi, and make it a time-controlled device. You can even define a schedule script to schedule complicated ON/OFF sequence for your Raspberry Pi. Scheduling the ON/OFF sequence for Raspberry Pi is the most popular feature of Witty Pi, and it is extremely useful for systems that powered by battery. By only turning on Raspberry Pi when necessary, the battery can be used way much longer with Witty Pi installed. Temperature-controlled device The temperature sensor on Witty Pi 4 has 0.125 °C resolution. The temperature data is used for compensating the crystal and make the RTC more accurate. You can also specific the action (startup or shutdown) when temperature goes above or below the preset threshold. Which means you can also make your Raspberry Pi a temperature-controlled device. DC/DC converter and e-latching power switch Witty Pi 4 comes with a DC/DC converter on board, which allows you to power your device with 6~30V power supply. You can also power your device with 5 V via the USB type C connector. Witty Pi 4 also implements an e-Latching power switch, which is very similar to the power switch on your PC/Laptop computer. You can gracefully turn on/off your Raspberry Pi with a single tap on the button. The software running in background will execute the shutdown command before the power gets cut, this avoid the data corruption caused by hard shutdown. Witty Pi 4 supports all Raspberry Pi models that has the 40-pin GPIO header, including A+, B+, 2B, Zero, Zero W, Zero 2 W, 3B, 3B+, 3A+ and 4B. You will need to solder the 40-pin header to Zero/Zero W/Zero 2 W model beforehand, so they can make reliable connection with Witty Pi. Single I²C device Witty Pi 4 uses MCU to emulate a single I²C device with default address 0x08, and also map all I²C registers in realtime clock and temperature sensor as virtual I²C registers in the same device. You can access all I²C registers in realtime clock and temperature sensor via the single I²C device emulated by Witty Pi 4. The advantage of this new design is that Witty Pi 4 hides other I²C devices (realtime clock, temperature sensor) and becomes the proxy of them to talk to Raspberry Pi. Because the I²C address used by Witty Pi 4 can be changed to any value, you can always avoid the I²C address conflicting. UWI support Witty Pi 4 is fully supported by UWI (UUGear Web Interface), and you can access you Witty Pi 4 on any device that have network access.

Elektor Labs Elektor Cloc 2.0 Kit
ESP32-based Alarm Clock connects to Timeserver and controls Radio & TV Cloc is an easy to build alarm clock without SMT parts. It has a double 7-segment retro display with variable brightness. One display shows the current time, the other the alarm time. Cloc connects to a Wi-Fi network, so it can access a timeserver somewhere on the planet. It can connect using DHCP or with a fixed IP address. An optional DS3231-based battery-backed real-time clock (RTC) module (not included in the kit) can be added to keep time in case of network problems. The built-in web server shows the time, allows setting the alarms and lets you adjust the clock’s parameters. The optimized graphical HTML interface works on most standard browsers and handheld devices. Specifications Based on an ESP32-Pico-Kit. Two independent 7-segment displays for the time of day and the alarm time. The time is set automatically by connecting to an online timeserver. Alarm time for each day of the week. Alarm output: buzzer and infrared code for e.g. radio, hi-fi system or TV. Two push-buttons for interacting with the device. Integrated web server for remote configuration via Wi-Fi. All settings are saved in EEPROM. Open-source software written for Arduino. Over-the-Air (OTA) mode allows updating the firmware remotely. Optional DS3231-based real-time clock (RTC) module (not included).
