But I’ve been a bit silent recently. One reason is that I’ve been focusing on Ohmify a lot. But I also moved from Colombia to Berlin. And went a few days to Norway. Which was cold. So I got a cold. I’m about to make some changes in the coming weeks.
I’d been working on this circuit ALL day. Then I plugged it in, and it didn’t work… “Why is it not working??!!” “It must be a faulty chip”, I told myself. “I should go down to the electronics shop and complain.”
Here’s a fun project. Build a cool touch-sensitive lamp you can have on your desk. Once you’ve built this project you can also apply the touch control to other things like a fan or a door bell. The first thing you need to figure out is how to sense touch from a finger.
I like math. But, I’m not an expert. I know the basics. But when it comes to more complicated stuff, like heavy derivation and integration, I think I’ve forgotten most of what I learned at the University.
One of my favorite TV-shows of all time was “Prototype This!” Joe Grand (aka kingpin) was the host. Guess what? Now he’s reading my new book Electronics For Kids! He calls it “a most excellent book” – and he has agreed to write the foreword for it!
