 I have been soldering circuits for twenty-six years. Well, except for the last 6 weeks. I have had a Weller Zero Smog EL fume extraction unit in my lab. It has changed the way I solder. When I first used it, I thought “yes, this is nice. But not a necessity.” Then the other day I didn’t feel like moving the extractor to my secondary workbench. I was immediately irritated with myself for being lazy.…

If you’ve had trouble following my millis() examples, maybe a live tutorial will help. In this AddOhms Livestream, I go through 4 code examples: 1. Blink, the one with delay(), as a starting point. 2. Blink Without Delay, line by line, what is it doing 3. PWM Fading without delay() (and with buttons) 4. Binary counter…

Previously, I wrote up a hands-on with the PicoScope 2204A. At the time I only spent a few minutes with the device. I used it to “debug” an I2C bus between an Arduino and OLED screen. Since that initial hands-on, I’ve used the PicoScope in my lab. Most notably, I hosted another “hands-on” via an AddOhms Live Stream. I used it for another live stream where I talked about op-amps. Unfortunately, the video isn’t watchable…

Sunday September 24, 2017, I will host the 2nd live stream of AddOhms. My first live stream was a test for the technology pieces. I’ve made some refinements and am giving it a second try. For that reason, I’m keeping the topic really simple. The Agenda for the Live Stream is: Introduction News (3 stories or projects that I found interesting) Op Amps with the XL741 Q&A Whatever surprises pop-up. In the livestream, I’ll be…
