It's really too bad that all you promote is iPad, especially considering that Apple is rapidly losing market share to Android. Forget "the rest of us", how 'bout articles and apps for "the most of us"?
I too have used and would like to see more apps like iCircuit. I would also like to see a pSpice tie-in app as well as a component EDA Librarian for iCircuit, so we could expand the 30+ components and families to include other glue logic, FPGA DSP and - why not - even tubes!
It would go a long way towards removing the iPad from toy status and turning it into a real work platform.
Let's hope, short of jail-breaking your device and running Linux variants on it, you could actually turn the iPAD (and other tablets) into a valuable workhorse type of highly portable tool.
Thanks for citing iCircuit. Most of the posts had to do with Electro-Mechanical apps or add-ons and viewers.
Why not some really productive tools that allow creation at first hand in the iOS domain rather than doing all the work on big desktops and saving the tablets to passing the work around for comment? Not to belittle that aspect. It is invaluable, but must we always be tied to our big computers?
A web application at http://AnalysisChamp.com is capable of performing expression evaluation with complex unit conversion. It includes a list of searchable units that can be entered as expressions and returned in desired units. The webpage is formatted for desktop or mobile device screens and is free.
I entered your example (assuming that "m" = meters and "um" = micrometers) and it returned 9.09E6. It also has magnetic, luminescence, electric, viscocity, energy, force, mass, pressure, temperature, time, velocity and other unit types.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
