When it comes to schematic capture and circuit simulation on a mobile device, iCircuit for iOS got it right from the start. iCloud integration, intuitive touch controls, and fast application performance. Now (or Finally?), my favorite mobile circuit simulator, iCircuit, is available for OS X.
iCircuit is based on the Falstad Circuit Simulator, which sadly, is a Java-based web app. For years I’ve installed the App on my iPhone and iPad almost immediately after turning on iCloud [for Android users, that’s basically the first step of activating an iOS device].
When working on the AddOhms video on the difference between AC and DC, I needed a vector diagram with a sine wave. Using Adobe Illustrator, I tried with a Bézier tool, but it didn’t look quite right. Here’s two methods I found to create a better line sine.
After spending too much time waiting for effects to render on my new AddOhms Tutorialcast, I decided it was time to upgrade computers. When I went to capture a quick EAGLE video on my new MacBook Pro with Retina screen, I realized a problem with the Mac’s auto graphics chip switch. Quicktime recorded only a green Screen.
Editing video has been something I enjoyed doing since High School. There I used my first tape-based NLE video system to make a Jeopardy episode where I played both a contestant and the host. In the skit I got into an argument with myself. Of course that was long before tools like Final Cut, After Effects, or even digital video cameras existed. Now anyone can do cheap effects for fun. Speaking of cheap effects, using…
Open source software that isn’t signed by an identified developer can cause headaches upgrading it on OSX. While working with the Arduino Due the first time, I downloaded 1.5 Beta of the Arduino IDE and ran into this error:
“Arduino is damaged and can’t be opened. You should move it to the Trash.
Here’s why you see the “… is damaged and can’t be opened” dialog and how to fix it.
