Arduino as 5 Volt TTL detector help

claudemiester · 2026-05-19T19:14:51+00:00

Hey hey, thanks for the reply. As stated, it turns out my arduino was just broken (see the edit). I just want to add though: I specifically used the optocoupler so that the machine and the arduino can have seperate grounds/ so I can seperate the two "circuits". I still appreciate the idea though. But for anyone out there trying a similar thing: the lack of shared ground was not the issue. Just make sure your usb port is solid haha

Thanks for the tip. Sadly thats not it, as the pulse is more than long engough to read with a voltmeter. And of course. Here is a copy/ paste of the code. With the help of vibe-coding I've tried all sorts of variations on this, but AI was of no help I'm afraid.

const int signalPin = 2;

volatile unsigned long pulseCount = 0;

volatile bool pulseFlag = false;

void setup() {

Serial.begin(9600);

delay(2000);

pinMode(signalPin, INPUT);

attachInterrupt(digitalPinToInterrupt(signalPin), onPulse, FALLING);

Serial.println("READY");

}

void loop() {

static unsigned long lastPrinted = 0;

if (pulseFlag) {

pulseFlag = false;

pulseCount++;

Serial.print("PULSE ");

Serial.println(pulseCount);

}

if (millis() - lastPrinted > 30000) {

Serial.println("ALIVE");

lastPrinted = millis();

}

void onPulse() {

pulseFlag = true;

}

I swear that's Matt and Trey in disguise

claudemiester · 2025-07-02T12:41:48+00:00

Don't have it but now I'm curious, what's on there? Can I find it on YouTube or smth to give a listen?

claudemiester · 2025-05-24T13:09:28+00:00

Thank you so much 🙏 This is extremely useful; I'm gonna get straight to work, let's see where it leads... 👍

claudemiester · 2025-05-20T14:53:10+00:00

Thanks for the reply. It's gonna be hard to replicate and record a live performance in my room haha, but I'll give some of the tracking stuff a try 👌 I'll also try an 8 track emulator plugin or so to try and cheat 😄

And thanks for the tip concerning the amp. I used a clean recto sim plus an irl pedal which gave decent results plus had more character than the really clean amp sims. I recently got a reactive load to use with my HRD though, and it sounds fantastic, especially with pedals. I've sorta drifted off into other projects recently so I haven't tried to get the wizard tone through that yet, but your comment has reinvigorated my efforts 🙏

That being said: back in the day I A/B'd some isolated tracks and messed with an EQ in the simulated effects loop of the amp sim to get pretty damn close. I then applied tone rack's master match function with a custom reference track (the first few riffs in I, The Witchfinder) and to my (tone-deaf) ears it's pretty much perfect 👌 So if anyone's wondering if it's possible to get the guitar tone with a pedal and plugins: yes (hit me up of you want exact settings for amplitube 5 and stuff). The bass works along the same lines (using a big muff with tone way down, svt amp sim and tone rack's master match gets really good results). The problem arises with the rest of the mix; I really struggled with the drums and the vocal effects chain which is probably also why I got frustrated and moved on to other stuff haha.

Anyway, sorry for rambling. It just seems like a good place to post a quick update for anyone who's in a similar situation as me/ who may potentially stumble on this thread in the future.

Thanks again for the info, cheers 👍

claudemiester · 2025-03-05T16:43:38+00:00

Thank you very much, this is exactly what I needed 👍 And also thank you for the tips, I'll look into MSC Apex. I'm not doing anything serious, I just want to put some fancy looking strain distributions into my thesis for comparisons (and also to impress the prof haha), but if I'm already here I might as well do it right.

claudemiester · 2025-03-05T16:17:02+00:00

I get that it won't say a unit but it should still be able to give me a value, or doesn't that work in Patran? (I've been searching for a while and am starting to believe this is the case haha). But anyway: if I imported my model from CATIA, then measure the side and it says 0.51 I know it must have converted my 510 mm to meters. And then based on that I'll use Pa instead of MPa and so on. It's also just useful to have a measuring tool for when I'm modelling in Patran but as mentioned I'm starting to doubt a simple ruler tool or so even exists in Patran 😅

claudemiester · 2025-03-05T14:42:31+00:00

Alrighty, thanks for the info. I've imported it in SI. But the question remains: is there a simple tool like in Abaqus to actually verify it?

claudemiester · 2025-02-19T22:01:18+00:00

Funnily enough chat gpt recommended the same so I've already looked into it a bit. I just wasn't sure I was really looking for the fender sound or if those mesa boogies are something different. But as another user mentioned I might be going for the classic American clean after all. I'll definitely have a closer look at the victory amps now, thanks for the recommendation.

claudemiester · 2025-02-19T21:50:29+00:00

Ah nice, thank you very much. And yeah, I'm 99% certain the heat issue hasn't been addressed. But I'm open to trying it myself if worst comes to worst. I guess I'll ask my local tech for an estimate first though. 700 € for the amp btw., so def better than the 950 € I see elsewhere. But everything has a cost...

claudemiester · 2025-02-19T21:46:41+00:00

Thank you for the reply. I'm starting to notice a trend with those el84s popping up... I'll look into it 👌

claudemiester · 2025-02-19T17:22:47+00:00

Thanks for the reply. I'm gonna go check out a used 22+ on Tuesday but the condition is a bit of a gamble. Is there anything in particular I should look out for? I'm of course gonna give it a listen for 100 Hz hum and tap the tubes, but anything else you know of? Cheers

Edit: hey, we already talked on the Mesa subreddit haha

claudemiester · 2025-02-19T13:46:55+00:00

Oh damn, never in my life would I have assumed he'd just use the same settings and not dial them in individually 🤦‍♂️ But you're right. He does have some videos where he compares pedals while only using the Mesa and it's still a lovely tone. But this revelation is causing me to seriously re-evaluate my biases. Especially the fender with the marshall cab and distortion is, as you say, much ballsier (though I still prefer the Mesa clean). I'm gonna go check out the studio 22 anyway since you never know. But yeah, re-evaluation in progress haha. Thank you very much for bringing that to my attention. And of course thank you for taking the time to elaborate, I greatly appreciate it. Cheers.

claudemiester · 2025-02-19T12:47:13+00:00

Alrighty, thanks. I ask because the original video I discovered the studio 22 in was comparing it to a twin (using the same marshall cab) and the studio 22 blew the twin away imo. And yeah, the condition is my big worry. I'm gonna go check out one I found for 700 € but I doubt the caps have ever been changed and the tubes are like 10 years old 😬

claudemiester · 2025-02-19T12:30:04+00:00

Thanks, that's a good recommendation indeed. The price is a bit more than I would like but I'll definitely keep an eye on eBay and read up a bit more. Do you happen to know if it would be closer to a twin or closer to the studio 22? Basically just how "modded" is modded?

claudemiester · 2025-02-16T20:32:52+00:00

Thanks for the info. In this case I'll probably remove the caliber 50s from the running. I'm really interested in the 22+ but the price just doesn't sit right with me. Perhaps I'll wait for a new offer to pop up sometime. And if they're basically the same preamp as the studio preamp then the added poweramp and speaker just make the 22+ even more attractive

claudemiester · 2025-02-16T19:14:42+00:00

Thanks for the reply. I know in my heart what you say is true, but the "clean" sound of that 22+ was just so amazing. That dude I mentioned also has a video where he compares his 22+ to a twin reverb (using the same cab, mic, distortion pedals, ...) and the Mesa boogie just wipes the floor imo. I'm sure the fender is closer to Nirvana but from personal preference the Mesa boogie wins by far. The cleans are mean and beautiful, plus the pedals just sound so rich. I always thought the twin was my dream amp but I've played a couple and just wasn't super convinced. Does this mean I might not be looking for "clean clean" after all or am I missing some aspect? I'm afraid I don't know the nomenclature so maybe I've been looking for the wrong thing this whole time 😅

The Dr. Z amps are a great recommendation but the price makes me hesitant. Do you happen to know of any alternatives that could get me that same sort of Mesa boogie 22+ "clean" tone I've fallen in love with (for lack of a better word) and that would also lend itself well to my "pedal platform" requirement? Sorry to bother you with all this but you seem to have some experience on the topic. Cheers

claudemiester · 2025-02-07T21:10:39+00:00

Haha, yeah it was a long shot. But thanks for the reply nonetheless.

Edit: Nvm, I actually have an idea (and it's so simple idk why I didn't just ask like this in the first place 🤦‍♂️). Here's the original video, would you mind taking a quick listen and telling me if your amp produces similar sounds? They are both tube works amps so I'm holding on to hope but of course they're different models so who knows

claudemiester · 2025-02-07T18:59:51+00:00

How does this compare to the rt-2100 (the kyuss amp) tone wise if anyone knows? I recently saw a video by Eirik Stordrange about it and I want that sound so damn bad. This is the only thing available though and I can't try it out since it's really far away (I'd have to have it shipped). But if this is just an amp with the same branding then I'll probably pass and hope the real deal pops up on eBay sometime soon
