I stumbled across TinyTapeout offering very low cost chip shuttles last month, and decided I had to get on their next shuttle in March 2025. For the early-bird pricing of US $150, you can design and tapeout a (small …

BrickNil [*] provides an easy way to connect to and program LEGO® Bluetooth hubs (including the PoweredUp Passenger Train 60197 and Cargo Train 60198 sets, and the Lego Duplo Steam Train 10874 and Cargo Train 10875 ) using Python on OS X and Linux.

As part of my recent foray into the Go language, I stumbled across this excellent example by Nerdyworm part 1, part 2, part 3 that shows how to build a small web application using the ember.js javascript framework and Go providing the backend server. I took this example, fixed …
