I suggest you ...

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".

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. LED brightness (Better contrast between bright and dim leds in response to resistor values)

    I’m trying to visualize an array of multiple colour LEDs with different brightnesses and I wish there was more contrast between an LED with a resistor for example 150 being very bright and 500 being very dim

  3. Set component from datasheet

    Allow looking up and/or configuring component datasheet/values. Like if I pick a diode it would be nice to set the values by either typing in4001 vs in4007 or maybe pasting a link to the data sheet for the specific component or a copy of the data sheet pdf itself

  5. add Maxim's MAX232 and/or MAX203 UART level conversion chips to the device inventory

    MAX232 level conversion chips are widely used for signal level changes, allowing modern day communications equipment to communicate with data devices that require CMOS/TTL signaling levels for communication.

  6. Analog photoresistor

    I love iCircuit ten years.
    There is a component called "Photoresistor", but I would like to make it like a Cds resistor.
    Currently, it only seems to respond to LED light by turning it ON or OFF. Cds resistors are used in "analog photocouplers" used in audio components, and they react to light and change their resistance in an analog way.
    I would like you to add this kind of behavior.
    Thank you!

  7. Allow importing of spice models

    Being able to import a complex component from a Spice model and apply it to the relevant symbol (i.e. a Spice model for the TIP122 and apply it to the basic "NPN" symbol) would be amazing.

    The ease of usability of iCircuit is its most attractive feature over "bigger" products like LTSpice, but not being able to fine tune components (i.e. only being able to set hFE on transistors, not being able to use a wave file as an input, or record the circuit behaviour to a wave file) is the only thing that is stopping me from paying for…

  9. Add a Photo MOS Analog Switch like an AQY221

    Something along the lines of an AQY221xx which is essentially an optical photoMOS switch activated by a current through a LED. The important DC parameters would the LED current and voltage drop, in addition to the ON and OFF resistance of the MOS FET and Drain to Source Output Cap should also be possible to set. This is an optically isolated device so a breakdown voltage is extra credit. The switching times for these are pretty fast for a switch (10’s to 100’s of uS) with no bounce, so that is also extra credit.

  10. Bug fix

    There’s bad bug in transformer, when we set the “primary to secondary coupling “ to (for example) 99.9% and the primary inductance ( for example) to 1H, by short circuiting the secondary the inductance seen in primary should be 1mH. But it’s twice the value ie 2mH.

  13. Inner Values of a circuit between two points

    It would be nice if it were possible to select two points in a circuit and read its inner values like inner resistance, short circuit current as well as idle voltage, capacity, inductivity, impedance and so on.( In my native language ist’s called: Charakteristische Werte aktiver und passiver Zweipole)

  14. Upgrade for Automotive circuit designs

    The basic program does have relays and can be wired up like a 4/5 pin DIN relay.

    I would pay for a "Automotive Electrical Package" that had updated GUI for automotive components and circuits.

    Flasher Relays for Bulbs
    Flasher Replays for LED
    DIN style relays
    All blade fuse designs
    Blower motors
    Blower motor relays
    DC to DC converters
    Radiator fans that are relay controlled and PWM controlled
    Fuel injectors
    Solenoids
    The list goes on and on.

    I would easily pay $200 for an automotive package that had all the vehicle electrical components.

    This software is amazing and it can farther

  15. Transformers and coils need a resistive option

    Transformers need a resistance option. When a circuit is at resonance, there is minimal impedance and is therefore purely resistive. There needs to be a way to define the pure resistive value of the transformers and inductors at resonance.

  18. Can you make voltage values selectable to be hidden

    This is a great teaching tool. The ability to create a circuit and hide the values of all components, would come in handy for teaching R, I, E, formulas to students.

  20. a NTC thermistor.

    The NTC thermistor is used in many power supplies and converters to handle inrush currents. Maybe it’s in the pro version I didn’t see it in the non pro version.
