Een standaard zandklok laat meestal slechts zien hoe de tijd verstrijkt. Deze door een Raspberry Pi Pico aangestuurde zandklok toont daarentegen de exacte tijd door de vier cijfers voor uren en minuten in een zandlaag te "graveren". Na een vooraf ingestelde periode wordt het zand door twee trilmotoren vlak getrild en begint alles weer van voren af aan.
Het hart van de zandklok wordt gevormd door twee servomotoren, die via een pantograafmechanisme een schrijfpen aandrijven. Een derde servomotor tilt deze pen op en neer. Het zandbakje is voorzien van twee trilmotoren om het zand weer vlak te trillen. Het elektronische deel van de zandklok bestaat uit een Raspberry Pi Pico en een RTC/driverbord met een real-time klok, plus drivercircuits voor de servomotoren.
Een gedetailleerde bouwhandleiding is beschikbaar via download.

Getting started with the world’s best open-source PCB tool
The latest iteration of KiCad, the world’s best free-to-use Printed Circuit Board tool, is packed with features usually found only in expensive commercial CAD tools. This modern, cross-platform application suite built around schematic and design editors, with auxiliary applications is a stable and mature PCB tool. KiCad 8 is a perfect fit for electronic engineers and makers.
Here are the most significant improvements and features in KiCad 8, both over and under the hood:
Modern user interface, completely redesigned from earlier versions
Improved and customizable electrical and design rule checkers
Theme editor allowing you to customize KiCad on your screen
Ability to import projects from Eagle, CADSTART, and more
Python scripting API
Improved integrated SPICE circuit simulator
Multi-sheet schematics
Filters define selectable elements
Enhanced interactive router helps you draw single tracks and differential pairs with precision
New or enhanced tools to draw tracks, measure distances, tune track lengths, etc.
Advanced interactive router
Built-in bill of materials generator
Realistic ray-tracing capable 3D viewer
Customizable teardrops
Plug-in manager for quick installation of themes, libraries and functionalities such as autorouters and BOM generators
This book will teach you to use KiCad through a practical approach. It will help you become productive quickly and start designing your own boards. Example projects illustrate the basic features of KiCad, even if you have no prior knowledge of PCB design.
The author describes the entire workflow from schematic entry to the intricacies of finalizing the files for PCB production and offers sound guidance on the process. Further full-fledged projects, of incremental difficulty, will be presented in a second book, together with a variety of advanced recipes.
Mastering PCB design with real-world projects
This book builts on KiCad Like a Pro – Fundamentals and Projects and aims to help you practice your new KiCad skills by challenging you in a series of real-world projects. The projects are supported by a comprehensive set of recipes with detailed instructions on how to achieve a variety of simple and complex tasks. Design the PCBs for a solar power supply, an LED matrix array, an Arduino-powered datalogger, and a custom ESP32 board. Understand the finer details of the interactive router, how to manage KiCad project teams with Git, how to use an autorouter on 2 and 4-layer PCBs, and much more.
KiCad 8 is a modern, cross-platform application suite built around schematic and design editors. This stable and mature PCB tool is a perfect fit for electronic engineers and makers. With KiCad 8, you can create PCBs of any complexity and size without the constraints associated with the commercial packages.
