About this app

This is a demo version for Droid Tesla Pro!

Droid Tesla is a simple and powerful circuit simulator.

Perfect for students new to electronics circuit design and construction,
hobbyist and tinkerers and even seasoned professionals who want a quick,
handy tool to perform electronics circuit design calculations.

That's interactivity and innovation you can't find in best SPICE tools for PC like Multisim, LTspice, OrCad or PSpice (trademarks belong to their respective owners).

DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL)
in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance
with KCL and then proceeds to solve for the unknown quantities using various algebraic
techniques such as Gaussian elimination and sparse matrix techniques.

For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answer
and then improving the solution with successive calculations built upon this guess.
This is called an iterative process.DroidTesla simulation uses the Newton-Raphson iterative algorithm
to solve circuits with non-linear I/V relationships.

For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time.
DroidTesla offers the Trapezoidal(I'll add a GEAR method later) integration methods to approximate the state of the reactive elements.
Although for most circuits, both methods will provide almost identical results,
it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.

Its good once you spend about half an hour figuring out how to do the circuits. It has all kinds of ac and dc outputs as well as logic gates and diodes and such. Has ammeters, voltmeters and an oscilliscope, but no ohmmeter, which I found odd. Feels a bit unpolished and some requirements are odd, but its a solid app to plan out basics.

Unfortunately it is not possible to simulate transient events, fot instance what happens in the first 1ms of the circuit. It's a real time simulator: you build a circuit, press play and watch what happens. Difficult if you want to know the frequency of an oscillation or the amplitude of the voltage at a specific time. Also I couldn't find the GND! Where is it??

I put 3 stars because there is sum issue on oscilloscope use. It is not a fixed oscilloscope with a stable reading. If it's possible, please change the UI of oscilloscope and make it as stable as possible, and add more functions on oscilloscope. It's very hard to use it because of that. Thanks for that. I will buy the pro version because it made me interested on some very useful stuff out there
