- Dec to HexSRC1 is random integer between 0 to 100 Convert SRC1 to 2 digit hex e.g. SRC1 = 100 hex= 64 expected output OUT1 = 6 OUT0 = 4967 downloads
- Slew LimiterConstruct a slew limiter. When SRC 1 outputs 100 volts, output an increasing voltage signal to OUT 1. When SRC 2 outputs 0 volts, output a decreasing voltage signal to OUT 1. The signal increases by 20 volts and decreases by 15 volts for each timestep.447 downloads
- cpuyou see, we've been getting along ok with hand crafting solutions to every single problem, but frankly its just inconvinent. we were hoping you could design a programmable system for data manipulation, so we don't have to re-wire our machine each and every time.392 downloads
- Binary CounterImplement a 3 bit binary counter, with OUT 1 as the least significant bit and OUT 3 as the most significant bit. Increment the counter whenever SRC 1 outputs 100 volts.285 downloads

- Quartz watchThese quartzes oscillate with 32768 Hz, that's 2^15 Hz. We need that frequency trimmed down to 1 Hz, so half it 15 times. We need a prototype for just one of these frequency dividers, chaining 15 of them isn't the problem. But to fit that into a watch we have some space restrictions, and also the...230 downloads

- Sweet Child O' MineConnect SRC1 to OUT1 directly to play the music. Trying to play the intro of all-time classic "Sweet Child O' Mine" from Guns N' Roses on the synth, but it doesn't sound like that at all :-P Anyway, just trying to have some fun.174 downloads
- MedianSignals 1-3 are random values between -50 and 50. Output the median (middle value) of the three signals. After you found a solution, maybe try another one.164 downloads
- Single-Digit MultiplicationMultiply the two inputs and then output.131 downloads
- Heat pumpOn start when you get High signal on SRC1 start adding 25 to OUT1, On next High signal start subtracting 25 from OUT1. Change between this two operation whenever there is High signal on SRC1. When you get 100 on OUT1 then send 100 on OUT2122 downloads
- Moving averageWe want to filter high frequency noise from a low frequency signal. The filter should output the average of the most recent 8 time steps (including this one). To simplify matters the signal is assumed to be zero for time steps before the start (i.e. out[1]=in[1]/8). Implement the filter: in=0 for...121 downloads
- LighthouseOur lighthouse is listed in nautical charts with a light pattern alternating between a long 4-second signal and a shorter 2-second signal. The signals are separated by pauses of 3 seconds (each step counts as 1 second). We need a circuit to generate the pattern. Output a repeating pattern: 4 x On...115 downloads
- anti—maxusing max to make min.112 downloads
- Clock implementationSRC1 is random non-repeating noise. Output 100 and 0, alternating every step. Stateful modules (Clock, S&H, Delay, etc.) are not available. This puzzle has elements which depend on module order. That behavior can potentially stop working in future updates.104 downloads
- Engine StabilizerSend (SRC1-Old SRC1) to OUT1. Old SRC1 is the value of SRC1 from the previous tick. The zeroth tick has a value of 0. Input values are clamped to 0-100.103 downloads
- FibonacciOutput the sum of the current value of OUT1 and the previous value of OUT1. The first 3 values should be 0,1,1.98 downloads
- Divide by 7Output the input divided by 7, rounded to the nearest integer. Input values range from 0 to 100, first simply ascending, then a few randoms for good measure.96 downloads
- Find the missing NumberThe 3 SRCs provide multiples of 10 from 10 to 100. In each timesteps the current SRC values combined with the SRC value from the previous 2 timesteps form a set of 9 unique numbers from [10,20,...90,100]. Output the missing number that would complete the set of all 10 possible values. For the fir...96 downloads
- Rising edge detectorSrc 1 will give a randomized signal that can either be 100 or 0. Out 1 recives 100 if Src 1 switches for a 0 to 100. Out 1 will recive a 0 if this is not the case91 downloads

Why The Signal State mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host The Signal State mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
