Christmas is coming up in about a month. And it’s time to build some Christmas things with electronics. So I just added a new course project to the Ohmify library: The Blinking Christmas Lights https://ohmify.com/courses/blinking-christmas-lights/
Here you'll find an archive of emails that I've sent out to my newsletter. In case you accidentally deleted an email, you can always go here to find it later.

I cannot count how many times I’ve connected my battery to a freshly built circuit and… …nothing. In the last email I sent last week, my goal was to convince you to try and build the blinking light circuit. Here are the build instructions:https://www.build-electronic-circuits.com/build-blinking-light-circuit/ So, did you do it?
Today I got a question from Garry on the Ohmify community. [GARRY]: “When I measure the voltage of my 9V battery using my multimeter I get a reading of 9.06 when it is not connected to any circuit. When I hook the battery up to a simple circuit (i.e. 325 Ohm resistor in series with […]
Ok, I’ve been away from electronics for too long. I haven’t been able to get my hands dirty and build circuits for a while. But last week I sat down to build some circuits for the 555 Timer course.
If yes, keep this in mind: Building a circuit and understanding a circuit are two different skills. And you can learn one without the other. As a kid, my dad taught me how the relay works. That helped me understand a simple circuit to blink a light. And we built it together.
How can a bird sit on a power line with thousands of volts and not get electrocuted? When I was a kid, I learned that it’s because “the current takes the path of least resistance”.
