  1. include Vacuum Tube Devices, Diode, Triode, Tetrode and Pentode.

    for designing, building and Hi-Fi vacuum tube amplifiers it would be really practical to have vacuum tube Diodes, Triodes, Tetrodes and Pentodes in the components set, plus provide the ability to edit existing models like transformers and add them into the component set.

  2. Provide latching relay

    I have a circuit that uses a latching relay with a Reset coil but no way to represent that in iCircuit. I've tried using a second Relay to represent the action, but it's messy and doesn't fully represent the logic. I have searched the web and nobody's circuit design software addresses this. Maybe I'm just an outlier? Is there another way to do this with your software?

  3. Bode Plot

    Bode plot
    A whole page for the graph
    Two cursors for the graph with the ability to ajust them manually just like the multisim app

  4. Incorporate vacuum tube devices

    This app practically begs for the inclusion of vacuum tube components! Its so close to being the perfect electronics app. I think generic models for a diode, triode, tetrode, and pentode would be a great addition to this app. A user could get all the data parameters they need from The data sheets for a particular type of tube and fill in the variables which distinguish one type from another.

  6. Optocoupler

    Optocoupler and photomos would be great.

  7. More controls on sub-circuits

    We already can create sub-circuit but it seems we cannot make sub-circuits using other sub-circuits. I don't know if it is a bug or a feature not yet implemented.
    I tried to implement a logical 'full-adder' with an intermediate 'half-adder' as presented in the 'Code' book. I manage to create an 'half-adder' but the 'full-adder' doesn't wok with the sub-circuits 'half-adder'.

    It will be very useful to add those sub-circuits in a library for future use. Currently iCircuit is very buggy when loading higher level circuit it fails at loading lower level ones. I also don't know where iCircuit is…

  8. Add 12AX7, 12AT7, EL84, 6V6, 6L6, EL34 vacuum tubes

    As a guitar amp designer, I bought this app as a way to prototype circuits without having to used an over-complicated program like Eagle. The common vacuum tube types (for starters) are 12AX7, 12AT7, EL84, 6V6, 6L6, and EL34. Unfortunately I don't see any options for even a generic tube which you could input operational values. If that is too complex of an undertaking, maybe just explicitly define the above tubes, after all, they are the most common tubes being used in amp design (and has been for decades). Hoping you can implement this!

  9. Maybe option to choose op-amp type ?

    I'm not sure about this one and I may be running into the limits of the program. I tried making a triangle-square wave generator using 3 op-amps - op1 is integrator with 100nf feedback, op2 is comparator with positive feedback (a voltage divider or a pot), and op3 is an inverter with output back to the input of op1. All resistors are 10kohm. 15V is assumed for all op-amps. I should be getting a triangle at op1 out and square wave at the other two. I'm not seeing this at all on the scope. Maybe the op-amp is 'too perfect'…

  10. Audio tubes!!! Please!!!

    I just wanted to say, this is a fantastic app. I've designed the PSU and switching circuitry for a guitar amp that I'm currently building, and so far, iCircuit has been absolutely spot on when it comes to the scope voltage and current readings. I was a little sceptical to begin with, but it's all knitting together quite well.

    But the one thing that I'm missing that'd make it perfect for what I want is a collection of audio tubes. Not all of them, obviously, because there are way too many variants, but would it be too much to ask…

  11. Please implement vacuum tubes

    Great tool! When are common tubes going to be implemented? Can't wait!

  13. Please integrate vacuum tubes!!

    I would love to see vacuum tubes integrated into this app. I build electric guitar amplifiers and if a guitar amp is of any quality then it has tubes in it. This would be a great tool for me when I am protoyping a new amp design. However I can't use it because it doesn't have tubes incorporated into it, Which are essential. Main tubes that are used are 6V6, 6L6, EL84 EL34, 12Ax7, 12AT7, 6550, ECC83, 5881, KT66, 5Y3

  18. Improve touch interface

    -wire auto route. When moving/adding a wire don't want everything to become scrambled.
    -wire mode: zoom and scroll with 2 fingers in wire mode
    -normal mode: instead of one or two finger scroll make it only two finger zoom and scroll. Make it so when you put two fingers on the screen to scroll it doesn't move any other components around accidentally. *looks like its "planned" already*
    -change one finger scroll in normal to making a select box for deleting multiple things at once
    -attach the meter and scope to a fixed given component so that for example, you can…

  19. Add non-realtime audio buffering

    Currently the speaker output rarely works live due to lack of processor power. Maybe the audio could be buffered into memory or streamed into a wav/aiff/mp3 file or better yet, into audio clipboard (the free AudioCopy SDK by Retronyms has been a de-facto standard for years, but maybe regular iOS clipboard would suffice too)
