]]> (Kickstarter) Screen + keyboard for any device (I’m thinking Raspberry Pi) https://techexplorations.com/blog/review/crowview Tue, 27 Aug 2024 06:41:07 +0000 https://techexplorations.com/?p=164001 I don’t usually write about Kickstarter projects, but this one caught my eye because it solves a problem I often have (I suspect you do, too!). I have lots of Raspberry Pis and (now) Khadas boards, and a typical scenario is to connect them to a keyboard, mouse, and screen so I can do some […]

]]> Basic Electronics for Arduino Makers, updated https://techexplorations.com/blog/course/basic-electronics-for-arduino-makers-update Mon, 12 Aug 2024 05:51:41 +0000 https://techexplorations.com/?p=163980 My course, “Basic Electronics for Arduino Makers,” is arguably my most important. It’s where all Arduino Makers should start if terms like “voltage ladder” and “pull-up resistor” sound like gibberish. If you don’t understand electronic circuits’ basic components and structures, getting into even the simplest experiments with Arduino will hamper your progress. And you will […]
