Recently I received three packages from Elegoo Industries. They are a company based in Shenzhen China. Before those packages, I noticed there name several times on various electronics kits on Amazon. They asked me if I’d help them with a video that shows how to assemble their latest creation: Penguin Bot.
There is not much point in sharing that video with you unless you’ve purchased one. So instead, here is my review, or hands-on, of the kit. I will, however, show you a short Instagram video I made to show off Penguin Bot’s cuteness
Previously, I reviewed the smartphone DMM, Mooshimeter. It is a great meter. One feature I didn’t spend much time on in my review was the ability to graph. Some see it as an “oscilloscope alternative.” The past couple of weeks, I’ve been using Aeroscope. It is a Bluetooth-based oscilloscope about the size of an older active probe. The Aeroscope runs $199 direct from Aeroscope Labs. The question I address in this Aeroscope review: is it better to buy this, a USB-based, or standalone scope for about the same money. How does it measure up?
My Aeroscope review looks at the specifications, the App that runs it and breaks down the key features. Let’s probe deeper.
In addition to hands-on learning workshops, there was a display of Arduino/Genuino projects by students. In the afternoon, three Arduino co-founders gave a short talk. David Mellis spoke on Machine Learning. Tom Igoe did his first talk on Technology and Humanities. Lastly, Massimo Banzi talked about IoT.
After fighting bugs, bad connections, and burned out chips your project is working–or even done. The next step? Record a video, edit it, and upload it to YouTube.
Too many steps? Then maybe you just want to do a Periscope demo. Within seconds, you can be broadcasting your project to the world.
This past weekend I tried my first couple of scopes. The first Periscope “demo” was me soldering together a Three Fives from Evil Mad Scientist Labs. The others periscope demos were 3d printing related.
When it comes to a hardware project demo, I see some challenges. Check out these five things to watch out for and, if you’re interested, you can watch my soldering Periscope demo.
1.6 marks the end of split releases between the traditional 8-bit boards and ARM based boards. There’s some really cool features built-in, so keep reading to see my take on the good, the bad, and the ugly.
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].
The Arduino IDE is great in that with a single download on any PC platform, new users can start writing code and see immediate results. The same simplicity though, limits some of the more “advanced” features found in modern editors. Also one of the IDE’s greatest strengths is cross-platform through Java. This is also one of its weaknesses. Java is outdated and it’s time to move on.
There’s a slew of other Arduino development environments out there, but most of them are limited to 1 or 2 platforms. Electron is a novel idea because it is based on Node.js, meaning it runs in Google’s Chrome.
The initial implementation even includes a Serial monitor!
