Today, in the early afternoon an order I placed on bol.com arrived. Yesterday, I had set up a Raspberry Pi 3 with a keyboard, monitor, and mouse but because of the weak Wi-Fi signal in my office it couldn't connect to the Internet. A range extender would solve this, so I ordered a TP Link AC1200 Wi-Fi Range Extender RE305. The device was a piece of cake to set up, and so far I would recommend it.
Because Adam is very interested in programming I also ordered a book: "Programmeren voor Kinderen"; the Dutch translation of Computer Coding Python Projects for Kids, by Carol Vorderman. I hope this excellent looking book, it has a hard cover which is great, helps my children with both their Dutch and Python skills.
