Step 2: Assess your design and find ways to improve it (metal box sounds good) Step 3: Get feedback on design (video + comments does that nicely) Step 4: Future features?!?! (cram DI box innards for pickup side to electrically match mic, internal mixer so musician can control how much sound comes from mic/pickup, freq/magnitude adjustable notch filter(s) to cut out feedback producing frequencies on the fly... etc.) Step 5: Realize that at some point along the way you became an Engineer ;)

Pickup tin can sound is usually because of mismatch impedance, Piezo electric pickups are high impedance, you need a preamp or buffer with a high impedance input, there is an easy high input preamp design called Tillman preamp, try that. I put one in my electric guitar and that solve the problem of losing the highs when reducing the volume, it work great with electric and piezo electric pickpus, it was designed by tillman for double basses and works wonders with violin and other instruments, and the cost of parts is like 10 dlls.

[@MatthijsvanDuin]

Inputs are generally "high impedance", just not as ridiculously high impedance as apparently necessary for this application.

[@ot4kon]

[@-ugly-Derby]

@@ot4kon exactly, the company I work for builds switchers for guitars and some of them allow you to adjust the input impedance up to 10MOhm for piezo pickups without an internal preamp

[@leftaroundabout]

You're absolutely right that piëzo PUs require a high impedance input, however even then they still sound like “subwoofer-sized tin can”. Actually the analogy isn't really good, the problem is not so much the frequency response as the phase relations: a piëzo directly transmits the harsh transients from the bow-hairs sticking and unsticking on the strings, whereas acoustic transmission over the body smears them out. This can be pretty well emulated with a convolution reverb (e.g. available in amp simulators), using the body as the response generator instead of a reverb room.

[@leftaroundabout]

@ot4kon actually, magnetic guitar PUs are in the range of a few _hundred_ kΩs. The often-quoted values of a few kΩ are just the _DC resistance_ of the wire, which is only a small part of the relevant _AC impedance in the audible frequencies_ (that is dominated not by the wire resistance, but by the coil inductance). (If DC resistance were what matters, then a piëzo would actually require _infinite_ impedance, because its internal impedance is of capacitive nature, not Ohmic or inductive.)

I've got 30 plus years experience behind me with soldering, and there's nothing wrong with your work at all, that I could see! Nice clean joints, no sgraggly wire strands, you're heating the joint before you apply solder. It's all good!

[@marcan42]

This! I've been soldering for 20+ years and I'm usually too lazy to do things quite *that* nicely. For your first time, way to go! Also, if you managed to get all the parts through all the holes in the right order, and all the heatshrink tubing on before the connections, such that you didn't have to undo anything, then you're basically a legend among us. Keep doing this, you're a natural.

[@zacharymccoy9262]

Azy but did he use tip tinner to prevent oxidation?

[@zvpunry1971]

Tip tinner is useless. If there is some sort of crud on the tip, clean it with brass wool and add fresh solder. And before putting the iron back into the stand, make sure the tip is still covered in solder. The solder prevents oxidation and brass wool (instead of a wet sponge) prevents thermal shock. These two things alone increase the lifespan of the tip. Modern soldering stations also have a switch in the stand to detect when the soldering iron isn't used. They reduce the temperature to a low standby-temperature to save power and further increase the lifespan of the tip. These soldering stations tend to use tips that have the temperature sensor and the heating-element embedded in the tip. They can heat up in seconds. If they are in standby, they heat up before you have moved the soldering iron near the PCB you are working on. And they can rapidly deliver heat to large copper-surfaces without sticking to them or getting too hot. Tip tinner may be useful if you have some ancient soldering iron with a copper-nail as tip. Something that our grandparents have already thrown into the trash. ;)

[@ginnyjollykidd]

I agree! Also shrink tubing is useful to keep wires and joints from creating short circuits. There's a reason for everything. Good job.

[@zacharymccoy9262]

zvpunry I have an old Iron, and mine stays hot. Even with Lead solder on the tip, it still oxidizes and I have to use tip tinner after about 4-5 joints.

I do this kind of stuff as a job. You pretty much did everything exactly right. The only thing I would have changed would have been to break the signal lines with the switch, rather than connect them to ground, thought it really won't make much of a difference, given the strength of the signals you're working with. If something were to happen and a power surge came through the line while you were muted (highly unlikely scenario, like literally being struck by lightning while you are on stage inside a building) having the signal tied directly to ground through the switch might burn out your switch/most of the wires inside. Good job on the soldering for a first timer though (at least the clips you showed us), and I agree wholeheartedly, heat shrink tubing is very satisfying.

[@miksu103]

I was thinking the same, but then thought about interference when switching. I haven't looked into this but shorting the lines instead of opening them could possibly eliminate popping sound when activating the switch. And I agree about the soldering. It was absolutely beautiful for a first timer.

[@Nimasho2go]

@@miksu103 Yeah, I don't know enough about musical fidelity in situations like that (I'm in chemistry, not a lot to do with sound), so I didn't want to say what I said as a "you should have done exactly this instead, no if's and's or but's", but yeah, that makes a lot of sense when I think about it. Suddenly injecting the signal is definitely going to introduce transient voltages, either way. If the way he did it is the way normal switches do it, then I'll concede the point easily.

[@saulo5216]

@@miksu103 he could always use a cheap passive (resistor + capacitor) filter to reduce/eliminate popping, which would be better than short-circuiting his pre-amp.

Awesome job! If you ever want to improve it use a metal box rather than plastic to shield from EMF. Use the ground from the XLR (don't use the balanced line's ground) to earth the metal case. Make sure the ground from the unbalanced line stays independent of the XLR ground or you'll get a ground loop. Another note is your circuit should be safe for phantom power in case anyone asks!

[@electronicsNmore]

When you were describing the issue, I immediately had the same idea in mind. Great video!

[@daveh7720]

For a soldering newbro, you did a very good job. Well done! I'll have to remember that trick of using step bits on plastic boxes.

[@bbugl]

1. For a newb, your solder joints look great. 2. You could use phantom power from the soundsystem to power your LED. You would need a bigger resistor (you have a 4k7, as this scales linearly with the voltage and standard phantom power is 48V, a 22k or 27k would probably do) but it would make the battery obsolete. As your mic is a condenser mic, you need to have phantom power on anyway. You can just attach the led anode to one of the signal cables of the microphone and it should in theory work. If you really wanna be safe you can wire another switch and also add a battery clip, so you can switch between battery powered and phantom powered.

[@__dm__]

Benjamin Bugl wouldnt the nonlinear load cause distortion on the signal? Bypassing the led with a cap might be a good idea.

[@dLichti]

@@__dm__ The LED is only on when the signal is muted.

[@__dm__]

dLichti oh great point

[@bbugl]

@@__dm__ you're not wrong. yes, if the led were on there would be a little bit of non-linear distortion at the diode but it would be dampened a lot through the series resistor. so you would very probably be not be able to hear it. that being said, your solution with a bypass capacitor would fix any problems, should they arise.

[@victortitov1740]

If the led switch engages a bit before the shorting switch, there will be a loud click sent through the amplifier. The switch probably does not specify the order of engagement. To make it right, one should drop two resistors of the same value, one from each line. Tie them together, and connect them to switch + led circuit.

[@owenjones2263]

The only issue I can see, other than that I would've used soft switching for the audio, is that the balanced audio muting, although often done like that will still let something through of something interferes with one of the phases. The same reason the phases are there, means they won't always be a perfect match, and if they aren't, the sum effect will have a nonzero result

[@VirtualVolition]

My first thought too. Plus if one of the phases is broken it will let sound through. Which I guess makes it a cable tester in a way 😂

For your future builds you should use an aluminium enclosure. DIY guitar pedals (and some professional ones) are usually made with a Hammond 1590A, 1590B, or 1590BB. Remember if you're going to use a DC jack that it has a plastic casing as guitar DC jacks are centre-negative, so a metal one will short to the enclosure unless properly insulated. You can get switched DC barrel jacks that will disconnect the 9v battery when a DC jack is inserted. Also, if you wire the battery's negative to the middle of a stereo input jack then unplugging the mono guitar cable from it will disconnect the battery from the circuit.

[@mikechilders]

One small problem... If your microphone is a phantom powered condenser mic, or if your mic cord is plugged into an input channel with phantom power (48 volts) turned on, you can short out the channel's power. The better idea would be to interrupt the signal by opening up the circuit rather than shorting it. Also depending on the design, the input channel's initial amp circuit can be damaged by a short. It would be rare, but possible on some boards. Most of today's boards have resistors inline to inputs of one or more opamps so a short wouldn't be fatal. Still, you have to be careful building a shorting device that will get plugged into an unknown input. Also, what if the cable doesn't get plugged into a board directly, but into some other device like a balun for the pickup or some outboard gear. Pickups are typically high impedance and need to be plugged into a balun on the stage to change the impedance. These are usually a transformer which can be shorted but some are active devices. You could find that one day the device shorts out something expensive. If you don't use the pickup and the mic at the same time, you can use the same switch pole for the hot side of the mic and the pickup. This allows you to interrupt both legs of the mic OR the one leg of the pickup plus the light.

[@qtrg5794]

was looking for this comment, thank you. i thought it was a joke when he drew the wires of the pickup and said "by connecting these two together...", and was going to show how it blows something up, like how electroboom educates people about mistakes like this. I was starting to believe I was crazy because no one else mentioned this...

[@sharpfang]

Leaving it open produces enough capacitance it's likely to start buzzing. And these things are built robust, various stuff happens on the scene and the devices must withstand the abuse. In general 'short'='mute' is widely accepted. I'm much more skeptical about linking two phase-shifted lines to cancel each other. It's unlikely to blow up, but if you mute one through alternate means (eh, disconnect it), it's likely the other one won't be possible to mute.

[@DenisMolla]

Also, doesn't this kind of switch can produce huge POP sounds when activated?

[@planespeaking]

On an xlr circuit they’re inverted, so if they’re shorted the signal is 0V

[@bernardli9514]

Wow these are very high definition stick people. Very realistic.

[@reylasharp6349]

Your soldering technique is great. While the heatshrink isn't absolutely necessary, it substantially improves the long term reliability of the product. If you upgrade to a metal box, I recommend insulating the inner surfaces to prevent any chance of shorts. Several layers of paint works well for this.

-For a first time soldering, it actually looks quite good -Shrinking tubes are not essential, but cables move and you might shortcut something if open connectors end up touching -The 9V battery is a waste of Energy, a 4.5V (with a smaller resistor obviously) would probably last longer. (LED Voltage is ~1.2V, the difference from that to the battery voltage is what falls off over the resistor. Which means the higher your battery voltage, the higher the energy waste.) Also, 9V batteries are comparatively expensive and don't last very long. Though, probably still very long when powering nothing but a single LED. (900mAh/20mA= 45h lifetime; roughly estimated values)

Wow didn't know you played fiddle. Awesome BTW plz continue your space videos

[@komodomoe]

Hey, nice work. One thing I learned early in making stompboxes is that you want a pull down resistor to prevent a popping noise over the speaker when you turn the signal on and off. It's a high resistance resistor and pretty easy to implement on your existing design. Also, a metal box will help reduce RF interference bleeding into your signal.

[@eivindhodne8012]

Hi and thanks! Where would you put the resistor and what value?

[@skarrambo1]

Adam Savage would very much approve of this video, you should share it with him!

[@tom_something]

The most satisfying part of working with shrink tubing is _not_ the part where you actually shrink it. Although that is pretty fun. But no, the most satisfying part of working with shrink tubing comes just before that moment. It's the moment after you've soldered something, and you look at your work, and you see that you _did_ remember to put the shrink tubing on before soldering. Whew! What a relief! Never gets old.

Tip: definitely get a metal box. It will isolate the circuit inside the pedal. Using plastic may be really noisy when used on stage cause the circuit is not protected against interference from other electrical equipment.

I just saw this and wanted to say that even though this is pretty different from your regular videos, I very much enjoyed it!

[@muto6633]

The rules to wiring are: use the wire closest to you

[@borek6164]

A metal housing has also the advantage of electromagnetic shielding, so the noise is grounded from the metal of the housing. The cables of the instruments are shielded by the ground beeing wrapped around the signal, so the waves don't interfear with the signal wires.

[@deadall127]

As a professional electronic designer/technician I can tell you that your soldering job is impressive, especially the led-resistor connection, good job. I'm also happy to heard that you enjoyed this activity, I also love electronics because it is tangible unlike programming for example.

That video just reminded me why I decided to study Engineering 4 years ago. Thank you.

Explain the physics behind doing something beautifully your own, and then sharing it for the benefit of others to learn from your example. Seriously. From conception of this very cool project, to completion, but all in physics terms. I dare you 😉

[@TheAmethyz]

for electric guitars Killswitch is easy to install if anyone wants one. (for guitar) There is no reason to buy expensive things when you can buy just one button and put it middle of wires. You can hear it in action in many songs by Buckethead. Note: the button must be by default on and when pressed its off and it comes back to default when not pressed. spamming that when playing guitar creates great effect.

The way you muted these things isn't necesserly wrong, but not the best way you could have done it. About the pickup, the entire thing has very little power output so shortcurting won't do much harm. The microphone is a different story. Be it a battery powered one (especially if it has symmetrical output) chances are it has pre-amplifier right after the actual microphone output. The output you shortcut is a pre-amplifier, which leads to overloading it, potentially damagimg the microphone as a whole. Now maybe I'm wrong about pre-amplifier being in your microphone, but there for sure are pre-amplifiers in different ones, so even with the pickup, it's best to break the circuit instead of shorting it. Please note, that if you do so, chances are your output device will become noisy, because the broken input circuit now started picking up electrical noise from your surrounding, with good example being radio transmitters that you probably use to fiddle without being restricted by cables. In order to stop this noise, you must connect the input to the ground. Some may argue that you have still shorted the circuit, but keep in mind that the output from microphone pre-amp isn't being connected to anything, so there's no way it could overload. The part about LED was good tho. It's worth mentioning right resistance for an LED could be roughly around 1k ohms (but even 330 ohms is fine).

[@babylonfive]

I also noticed that you were shorting rather than breaking the circuit. At a minimum you could place a resistor between the inputs instead of a dead short, but opening the circuit instead would be best.

[@emerylapinski1553]

Would this way be less likely to cause a popping sound out of the PA when you press the button?

[@asavartsov]

@@babylonfive open circuit + long cable = hum

[@garethedwards1802]

As a theatre sound technician, I think my solution would have been to use a 2 channel DI box, changing the XLR mic connection to 1/4”, with an XLR mute pedal wired after it. Unfortunately with sound there’s so many different scenarios, and this may not work for all your needs. Really cool to see this solution!

[@darthbee18]

Never would have I ever thought of seeing a Ling Ling reference in a minutephysics video 😂😂😅😂🎻

[@Legotronics]

Also... when building stuff yourself, you can make it exactly how you need it, whether that being features, size or so - and yes, really satisfying to realise an idea and end up with something you made yourself.

The heat shrink technically isn't necessary to make it work, but it's always a good idea, it'll somewhat protect your connections from the possibility of shorting, I've fixed equipment faults in the past that have been caused by a strand of a cable coming loose of it's connection and contacting a nearby connection. The heat shrink should also give you a little moisture resistance too, which is never a bad thing with electronics.

[@theletterh8176]

-Minute- Physics *_40 Hour_* Seems legit

[@maverickwoodcock7889]

Looks awesome!! Your solder joints look really nice especially for a first timer, you said heat shrink isn’t absolutely necessary, but it is. I would never use electrical tape except for temporary fixes, and insulation is a must!!!
