You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  1. Could you add frequency as an element in expressions

    Could you add frequency as an element in expressions. It would be useful in AF and RF circuits. Tie it to the AC source frequency so that expression values are updated on adjustment. I find iCircuit an exceptional tool on IOS!

    Example

    ElementName.ValueName

    as for AC source
    VIN.Vd (AC source voltage)
    VIN.f ( AC source frequency)

  2. Control Panel Elements

    Include a control panel window to which you add control elements eg dial, slider, switch. These elements can then be linked to parameter values in circuit. For example a slider could control the frequency of a voltage source, a dial could change the value of an analogue component. Of course we can change values already but having a separate window where values can be tweaked would be useful

  5. Linked/connected switches

    Some switches have more than a couple connections, and not all in one place on the schematic. Walkie talkies, for example.

    How about an option for the switches where you can link them, so they all get thrown when one gets pressed. Name them SW1a, SW1b and so forth.

  6. Define a time dependent temperature function for thermistor

    Thermistors should change their resistance with temperature.
    Temperature rises depending on time and power and thermal conduction.

  12. Ability to link component values to others which share the same label. (Multiple Rs or Cs, etc.)

    For example:

    In a circuit with ten resistors, each resistor can be given the same label — say 'R' — so that when you change the value of one, all of them are changed.

    Implementing this with capacitors, voltage sources, etc. would be an enormous improvement for workflow when designing and experimenting.

  14. Arduino analog I/O improvements

    Analog input values currently map to 5V reference even if the device is set to 3.3V (analogRead should reference to the device operating voltage by default). This leads to returned values being about 40% lower than what they should be.

    Also, the analog pins currently don't seem to support being used as digital I/O pins (not a problem but would be nice to be documented).

  16. Background color tweak

    If all possible, perhaps switch the Blue background from a Baby blue to more of a Navy blue. Much better on the eyes for those that need to keep simulations on and don't want to go with the all black background. (Similar to Notability's dark Blue paper)

  17. improve op amp models

    Please improve the op amp models, as I’m having trouble getting the op amp to work in simple circuits such as a voltage follower. There’s not a convergence issue, it just doesn’t perform the operation as expected. I even added in small parasitics to see if it would help as is sometimes required in PSpice.

  19. Rid the AC sources voltage drop, fine tune frequency.

    I’m an electrician that loves schematics. I love designing complex circuits for real world applications. My favorite thing to do is play with load calculations. Simulating a 200amp panel and see how many 60w light circuits, other real world loads simulated by resistors I can get. I even designed 3phase motor starters and overloads using what the app provides. All while following NEC2017/2020 guidlines for load and branch circuits.
    But the aggravating part is the voltage drop. When simulating a 120/240v 200a panel I should be able to power 24,000W of electrical appliances. But instead after about 6 light bulbs…

  20. Bug fix..

    This is more a bug fix,,,I recently built a ring oscillator for a design I was working on, and I noticed that the output never converged to an expected value. Instead, it consistently produced a frequency that was 1/2 the currently configured circuit bandwidth. If I change the bandwidth to any value, the oscillator output immediately goes to 1/2 of the selected bandwidth. And even more significant, the frequency is not impacted by components, such as Ls, Cs, and Rs that would normally allow tuning of the output frequency as would be expected.
