Circuitry Hack 1.1.0 + Redeem Codes

Love this. Great app and an elegant way to play around and practice. This has been my doorway into understanding logic gates. I can’t think of a better, simpler way to do it.

I see suggestions of more complex components in other reviews from people smarter than I (ie the first review that comes up). A very, very simple thing in playgrounds would be a label component - just a sign that would let me label a given circuit so I can remember it.

I understand that the creator is just offering this up for free, which is 🤯. But I would be glad to pay money for a tool like this. The irony is that some people are probably undervaluing it because it’s free. Why not add in a few more of these advanced components that people are asking for and then monetize it? You’ve put work into this and it’s awesome. You deserve a little return on your time and brain cells!

Love this app. Spend hours tinkering with it before wiring up a breadboard. You will learn a lot. But making/breaking connections between gate inputs and outputs, as well as moving gates around the screen is not done consistently in a straight forward manner which is why I deducted a star.

I really like it, it’s pretty user friendly and allows for the construction of some advanced stuff, but there’s a few more things it good use
1. Multiplexers/demultiplexers: many circuits use these and they and quite useful
2. Imply gates
3. Only gates: an only gate is an and gate with one input inverted, basically the opposite of an imply gate
4. Shift register
5. 2-Bit and 4-bit decoders
6. Binary division circuits
7. The ability to name buttons and outputs
8. Signs: an item that simply contains a title, used to label one circuit from another
9.the ability to adjust the speed of the clock, and a more defined off and on rather than that weird rapid strobing with the occasional off and on
10. ALU: this would be useful for many reasons, like many advanced circuits
11. The ability to increase the amount of inputs for certain gates, such as the AND/NAND and OR/NOR

Suggestions: these are just suggestion of what might be interesting to add but isn’t need
1. Binary reversible logic gates: those would interesting to play with
2. Circuit switching elements
3. Relays

Great potential as a logic design / testing app. I’m currently taking a discrete math course and found the “playground mode” very helpful for visualizing combinational circuits.

My two main complaints:
1) Controls are a little clunky when it comes to moving things around and attaching wires. Even with an Apple Pencil the precision is not predictable
2) Would be nice if it kept track of your previous solutions so you could see what you submitted for a problem

Other stuff that would be nice to have:
1) Don’t gate playground mode components behind problem progress
2) Discrete math notation for created circuits
3) Simplification and maybe scoring in problem mode based on simplicity. (Found some problems where I didn’t need all the gates I was given)

The app is very good at teaching you the basics of logic with the first few levels

I suggest that the difficulty of the levels do not rise as dramatically as it does

Other than that it is a great app and the playground mode is great for when you have any good ideas.

I love the game concept for working out solutions! Greta idea. Having that and the playground for tinkering is brilliant.

I’ll update my review to 5 stars once the drag-n-drop is fixed.

The drag-n-drop recognition/method is frustrating. The touch hit boxes are flaky. To touch the middle of the gate and not have it start to move is annoying. It’s only reliable when there are no wires connected to the two inputs. I often find myself accidentally dragging a wire from the output of a gate to one of its own inputs when I was trying to just move the gate somewhere else.

Like I said, fix the moving of gates and this app is amazeballs!

I don’t know anything about circuitry and in the later problems it took me a long time trying to understand the question. I really enjoyed the challenge. Great app,

Love the game but the lack of undo drives me nuts. Sometimes when trying to move an object... you end up creating a link within the object... and I can’t seem to remove it. A simple undo button would make it a lot simpler to deal with this.

I would have liked to have this program to practice with back when I took digital logic in college

I can’t figure out any way to remove a wire once it is connected, other than closing the problem and restarting from scratch. Am I missing something?
