11. Droid Tesla

Droid Tesla is a simple and powerful SPICE circuit simulator. In addition to radio components, various current and voltage sources are supported, as well as basic measuring instruments, incl. virtual oscilloscope. Droid Tesla allows you to emulate the following current/voltage sources: constant current and voltage source; alternating current and voltage sources; CCCS, CCVS, VCCS, VCVS - controlled current and voltage sources; triangular pulse generator; rectangular pulse generator.
Emulation of the following electronic components is supported: resistor; capacitor; inductance; transformer; potentiometer; incandescent lamp; ideal operational amplifier; bipolar and MOSFET transistors; diode, LED and zener diode; switches; digital logic elements: AND, NAND, OR, NOR, NOT, XOR, XNOR; triggers; 555-timer; relay; 7-segment indicator, etc. The following measuring instruments are supported in Droid Tesla: AC/DC ammeter and voltmeter; 2-channel oscilloscope. One of the interesting features of the software is the visualization of current flow (to enable the display, you need to check the appropriate box in the program settings: Settings -> Animations -> Animation of current flow). After this, when you turn on the circuit simulation, you can visually observe the flow of current. The only thing is that in this mode the operation of the circuit slows down greatly and processor resources are consumed to a greater extent.

Simulator – designer of electronic circuits “Beginnings of Electronics”

There is a very interesting program, which is a simple simulator for demonstrating the operation of electrical circuits and the operation of measuring instruments. Its convenience lies not only in its clarity, but also in the fact that the interface is in Russian. It allows you to model very simple circuit diagrams on a breadboard. The program is called “Beginnings of Electronics”. Link to it at the bottom of the page, video of Mikhail Mayorov’s channel.

The program works from Windows 98 to Windows 7. The interface looks like this.

Below is a drawing of the printed circuit board, but for us the socket with the breadboard is of greatest interest. At the top there are control buttons: load a circuit from a file, save a circuit, clean a breadboard, get a multimeter, get an oscilloscope, show parameters of parts, condition of parts, reference book (concepts about electricity are briefly outlined), a small list of laboratory work for doing it yourself, instructions for using the simulator, information about the authors, exiting the program.

The video shows how the circuit simulator works.

What can you build on a circuit simulator?

You can collect quite a lot of interesting things with this simple simulator. First, let's model a regular flashlight. To do this, we need a light bulb, two batteries and, naturally, all this will need to be connected with jumpers. Well, what is a flashlight without a switch and a light bulb?

Double-click to open the battery parameters window. On the tab that appears, we see voltage, internal resistance, showing its power, minipolarity. In this case, the battery lasts forever.

When the circuit is assembled, we press the switch twice and for some reason the light bulb burns out. Why? The total voltage of series-connected batteries is 3 volts. The default light bulb was 2.5 volts, which is why it burned out. We install a 3-volt light bulb and turn it on again. The light bulb glows happily.

Now let's take a voltmeter. His “palms” light up. These are measuring probes. Let's move the probes to the light bulb and set the DC voltage measurement with a limit of 20 Volts. The monitor shows 2.97 volts. Now let's try to measure the current. To do this, take a second multimeter. The device connected to the circuit showed almost 50 milliamps.

Almost like a real multimeter, you can measure many parameters. There is also an oscilloscope in the simulator, whose beam brightness can even be adjusted. In addition, there is a rheostat, you can move the engine. There is a variable capacitor, shunts, a heating stove, resistors, fuses and more. Unfortunately, there are no transistors in this simulator.

Review of amateur radio programs for Android devices

Good afternoon, dear Radio Amateurs!
Today on the website, we will consider a rather interesting question - amateur radio programs for devices running Android OS.
Recently, the electronic equipment market has been filling up at a good pace with inexpensive (mostly Chinese, but fairly decent quality) devices that use the Android operating system. You can already buy a good tablet for 5,000 rubles. Therefore, I was interested in the question: are there amateur radio programs for such devices? It turns out there is, and not a little. Below I will give you an overview of several such programs, and we will look at one of them in more detail.

So, the first program is OscilPrime Oscilloscope Legacy
This program allows you to turn your tablet computer into a two-channel low frequency oscilloscope:

The signal under study can be supplied to the audio connector and via the USB port. In addition, the program has a built-in sinusoidal signal generator. The sweep can be triggered either by the decline of the signal under study or by its edge. The program is easy to use and has limited settings.

Next program – EveryCircuit(paid – 300 rubles) or EveryCircuit Free(free).
This program allows you to assemble simple radio circuits on the tablet screen and simulate their operation:

The program is simple and not difficult to understand. As a disadvantage, we can note the lack of “Russian language”, a small base of elements and the high cost of the full version. But despite the shortcomings, the program will allow you to think through some aspects of circuit design when building simple devices.

As you can see, dear radio amateurs, progress does not stand still, programmers take care of us and release new programs. Even if they are not yet as developed as for “big” computers, I think that soon “small” computers will catch up with their “big brothers” in amateur radio software.

You can download all these programs (and not only them) through the “Play Market” on your gadget.

And finally, I want to introduce you to another amateur radio program that deserves close attention, and not only by beginning radio amateurs.

The program is called ElectroDroid.
There are both paid and free versions of this program. The difference between the paid version is that additional features are introduced and there are no annoying ads.
ElectroDroid is a powerful toolkit and reference for the electronics developer:

The program consists of several sections:
– calculation
– pinout
– directory
– plugins

Let's start from the end - plugins. This function allows you to expand the capabilities of the program by adding new functions. All new plugins are installed within the program.

Calculation– this section is intended for carrying out various amateur radio calculations. In the top picture you can see almost all the program's capabilities in this mode (some are hidden at the bottom). As you can see, there is quite a wide variety of small subroutines for carrying out simple, but at the same time useful amateur radio calculations.

Tsokolevka. This section of the program presents the pinout of the most popular and frequently used connectors, wires and devices in amateur radio practice:

Directory. This section presents various reference data on radio elements, as well as tables of various data needed in amateur radio practice. This section will especially please fans of PIC microcontrollers - reference data on almost all PIC microcontrollers is collected here (it’s a pity, of course, that there is no such reference book on AVR microcontrollers):

You can also download this program from the Play Market, or (using the services of our hackers) download the full version of this program below:
