LoCAD

I am a retired physician and an electronics hobbyist. I came upon LoCAD after some success and excitement with electronic simulation programs like icircuit. I was surprised that LoCAD was not really reviewed! At first I thought that it was simply a simulator, like iCircuit. But I discovered that it was also an entire educational course that teaches Boolean electronic concepts. LoCAD is a simulator available for the Mac or iPad (apparently, it also works on Vision Pro!) in combination with two iBooks on electronic logic and microprocessors. With the LoCAD program you can teach yourself how a microprocessor works FROM THE TRANSISTOR LEVEL UP. The books show how basic digital Boolean gates are made. With the Boolean gates and their combinations (provided), you can make your own complex integrated circuits. Using the books and the program together will allow you to make a simple microprocessor with its own assembly language in short order. LoCAD LV is the free MacOS version. A maximum of 9 components can be used with this version. The LV version can be upgraded to a full version. The LoCAD SV version is the MacOS school version, which already contains the activation for the full version to enable distribution via the Apple School Manager. LoCAD and LoCAD Lite are the iOS versions that run on iPad and via Mac Catalyst on Macs. LoCAD is the full version, and in the free Lite version a maximum of 13 components can be used. My advice is to purchase the LoCad full version and the two iBooks when you start. I think people are downloading this program and not purchasing the inexpensive, well-written books which make the programming SO MUCH more understandable, unless perhaps you are already an EE chip designer. The LoCAD interface does not always adhere to the Mac interface (zooming, moving on the work area, right click menus for example), so there is a bit of a learning curve with the program interface. The iBooks on the Mac did not allow text size adjustments, perhaps because that would interfere with the interactive examples. I have not yet explored the same parts of the iBook and program on the iPad. Overall it really is an amazing introduction to electronic logic and its application. If you want to try it, purchase the two iBooks along with LoCad. With a little effort you won't be disappointed. Thank you Karl for the education!

I love this app! I can’t toggle the switches when the clock pulse generator is running.

Schade um das Geld, App geht sofort in den Hintergrund, sobald ich etwas bearbeiten möchte und die Auswahl der Bauelemente ist rudimentär

Die App lässt Schaltkreise leicht und übersichtlich bauen und man kann gut damit lernen wie z.b. Ein Computer funktioniert oder einfach ein wenig rum probieren. Das einzige was zu bemängeln ist sind noch ab und zu abstürzte. Ein Kurzschluss Problem wurde zügig behoben und der Entwickler hat schnell auf emails geantwortet. Mittlerweile funktionieren alle Schaltungen ohne Kurzschluss. Nur 2 Schalter an einer leitung verhalten sich etwas seltsam was aber nicht wirklich schlimm ist. TL:DR : Gute App, guter Support

Nur ein kleines Problem: mit der Funktion „teilen“ stürzt die App ab. Mein Ziel: die einzeln gewonnenen Schaltungen auf PC sichern. Trotzdem 5 * !

Super App Löschen von gespeicherten Schaltungen funktioniert nicht. Ab und zu gibt es Probleme beim abspeichern von Schaltungen. Für größere Schaltungen ist die Arbeitsfläche nicht ausreichend. Schön wäre es, wenn man selbst die Arbeitsfläche bestimmen kann. Seit dem iOS 8 Update ist die Anleitung verkehrtherum x)
