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.

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.
Arduino-compatible, ESP32-controlled, 2-wheeled Balancing Robot

Dit boek gaat over de Raspberry Pi, en over het programmeren in C. De programmeertaal C en het besturingssysteem Linux (Raspbian) passen uitstekend bij elkaar. Alles wat we nodig hebben om in C te programmeren wordt meegeleverd met het besturingssysteem van de Raspberry Pi.
In dit boek leert u hoe C gebruikt wordt met de Raspberry Pi, en krijgt u een overzicht van de taal.
WiringPi is een softwarebibliotheek voor de Raspberry Pi waarmee C hardware-uitbreidingen kan benaderen. Die bibliotheek wordt gebruikt om sensoren uit te lezen en om extra hardware aan te sturen. U gaat experimenteren met LED’s en schakelaars, met motoren, met geluid en met sensoren voor temperatuur, luchtdruk, en luchtvochtigheid.
Met een Linux-systeem kunt u een webserver maken, inclusief interactieve websites met PHP en WiringPi. Daarom is ook een beknopt overzicht van HTML en PHP in het boek opgenomen. In de voorbeelden worden sensoren via het web uitgelezen en worden apparaten bestuurd. In het laatste voorbeeld wordt een temperatuurlogger gemaakt. Die meet elk kwartier de temperatuur. Een tabel met de meetwaarden kan via het web worden uitgelezen.
Alle voorbeeldprogramma’s kunnen worden gedownload van de website van Elektor.
