Distortion Pedal - Need a little help!

 Hello all. I am in need of some help!! https://www.instructables.com/id/Make-an-easy-guitar-distortion-pedal-STEP-BY-STEP/step20/Adding-a-bypass-switch/ This is a 'schematic' of a distortion pedal for guitars In this specific picture it shows how to install a BYPASS SWITCH. I'm having trouble with it, when i turn the switch on i get nice distorted sound.....when i turn the switch off i get NO sound. (i should be having lean guitar sound instead) I hooked up everything perfectly. Still problems. What can I do so that when I turn the switch off I will get clean sound?  Any suggestions?  Thank you.

Guitar Pedal Help

Hello there, I am currently fixing a VOX Wah Wah pedal. The bypass works - the wah wah effect does not. How exactly does one check to see if each individual component is working? Is it by using a multimeter? How exactly can I do that? (I've put in a 9v battery and tried seeing if there was voltage around the circuit, but I think I am doing it wrong.) Can anyone give me some tips?  Here is a picture. http://i.imgur.com/LKq0bSY.jpg

Guitar Pedal Prototypes

Don't get me wrong, I love acoustic guitars... But I love a good crazily distorted guitar that almost sounds like a synth. Rage against the machine's guitarist Tom Morello epitomizes that wild sound for me. Most good bands have an instantly recognizable sound and one of the ways a guitarist can distinguish zer self is to use a unique set of pedals. Now you could go buy a set and find just the right setup for your taste... or you can build your own. Best part is, there's no soldering involved:Bevis Boardvia:Make

Wah pedal as speed controller for Dremel?

I was working with my Dremel the other night and I noticed my not-working Crybaby out of the corner of my eye and started thinking that it would be a perfect speed controller for my dremel. I think I'm gonna tear it apart and see what it looks like inside and see maybe where to go from there. Probably would like it to have a footswitch somehow that will turn it off or when it is pushed all the way in it will turn off. Just an idea. If anybody has some suggestions or maybe could build it and make an instructable that would be awesome.

Pedal Power LED lit night soccer!

My school entered into a "pedal power video" competition, the challenge was to make a video showing how to use alternative sources of energy, so my school had a soccer game at night where we lit the field up using pedal power and generators. This was done by attaching a belt to the back wheel of a bike and hooking it up to a treadmill motor working in reverse for power. Enjoy!

iOS controlled arduino guitar pedal

Hi everyone !  I was looking to make an iOS controlled guitar pedal (using and arduino uno !).  First a very simple one, like an overdrive or a distortion, and later something more complex ! Who could help me ? I managed to create the overdrive with this instructable https://www.instructables.com/id/Overdrive-Pedal/ and the distortion with this one https://www.instructables.com/id/Make-an-easy-guitar-distortion-pedal-STEP-BY-STEP/?ALLSTEPS. I don't know how to use one of those pedals and to connect it to an arduino uno and then to be able to change the settings (like being able to change what we can change with the buttons of the pedal) with a very simple iphone app (through wifi or bluetooth, probably with an arduino shield) If anyone could give me a lead ...  Thanks for taking the time to read me and for your help !  Merry Christmas !

Guitar effect-pedal built into the guitar

Hey, I thought if it's possible to add the electronics from a guitar pedal to the guitar itself. It would obviously take some space, but it didn't seem impossible to me. Any ideas, is this even a realistic idea? I must do some more research on how much place it would take and how to wire etc. Any help or thoughts are welcome!

Someone help! DIY wah wah guitar effect

Instructables community, I am 13, just learning to play guitar, and want some awesome effects to spice up my sound. I have seen the kits for DIY wah wah effects and wish to make one. I don't plan on etching my own circuit board, and i don't want to buy one. All of the schematics are pretty complicated and i have no idea how to decipher them. I will probably end up using a protoboard; but can someone simplify the plans and/or give me the links to the parts i need? Thanks in advance, -Nick

Guitar Wah Wah Pedal Help!

My VOX Wah Wah pedal (V847) is not working. The bypass is working. However, when I turn ON the wah-wah effect - there is only a clean sound of the guitar and a very THIN sound of the wah-wah, it sounds more like a VOLUME pedal than it does a wah-wah pedal. I believe this is the schematic:    http://www.voxamps.com/downloads/circuits/wahwah93.jpg From what i've gathered, the problem lies in the capacitors (because apparently capacitors are what create the wah wah? i'm not entirely sure myself) I've replaced the C2 (4.7MF) and C3 (.22MF) What could be the problem? Please help! P.S. are MF, mF, and uF all the same? Thanks.

Effects of Inductors Coupling?

This is a follow up post from this thread >> https://www.instructables.com/community/Guitar-Wah-Wah-Pedal-Help/ (It was about how to fix my Wah-Wah guitar pedal, it turns out the Inductor was not working, so I replaced it) I replaced a broken 500mh INDUCTOR in my guitar pedal with a new one. It works now. However, I am planning on keeping the broken inductor in my wah wah pedal (because it yielded a cool volume pedal sound). I want to rig up the circuit so that I can switch from from the GOOD conductor to the BAD conductor. My questions are: Will there be any major effects from having two inductors coupling? Should I be wary of the 'winding' of the coils? If so, what should I do in order to be consistent with the winding? And out of curiosity, how could I rig this up?  Here is the schematic >> http://www.voxamps.com/downloads/circuits/wahwah93.jpg 500mh Inductor = L1 I have 3 terminal DPST switch. This is how I imagine rigging it up: I'm thinking of having wires from the inductor terminals on the PCB wired to a terminal on the SWITCH, then to the INDUCTOR, and then back to the PCB. The same follows for the other (bad) inductor. If this is not clear, please let me know, or feel free to post a better way to rig this up. In summary for this last question How could I rig this circuit to switch between two inductors? Thanks.

Pedal-powered airship gets half way...

A French amateur pilot's attempt to be the first to cross the channel on a pedal-propelled airship has failed.Stephane Rousson, 39, from Nice, took off from Hythe on the Kent coast at about 0800 BST and was half-way to the French coast by 1300 BST.But he was hampered by a change in the wind direction and called off the trip 11 miles from Wissant in France.Mr Rousson said: "I'm not disappointed. I feel happy because it had nothing to do with any technical failure."During the challenge, Mr Rousson was suspended underneath the balloon envelope in a carbon fibre gondola, powering the two propellers with his feet using a bicycle-like contraption. The most amusing thing about the whole trip is the safety system:Just in case Rousson found himself flying irretrievably high, he hung an open penknife from the gondola framework, with the intention of popping the balloon and heading for a splashdown.Sorry, that's the second most amusing thing. The most amusing thing is the pilot's childhood inspiration - ET.BBC article

Bike Lighting - Pedal-Powered 60W Incandescent Bulb?

I know, I switch projects a lot. I just can't stay focused on one thing for too long.Anyway, here's my idea:There's a local museum called Fort Discovery, which, by the way, is quite cool. But, there is this exercise bike they have there, and connected some how (I haven't been there in a while) is a few different home tools, like an incandescent light bulb, a drill, a hair dryer, and something else. There are switches, so you can turn whichever ones you want on, to see what you can power. The "exhibit", if you will, is to show how work = power. Now, I'd like to try to hook something like this up, except a few things will be changed:It would be a regular, moving bike.There would only be a light bulb.I want the power to be stored in a capacitor, because what would be the purpose of having a light while riding in the daytime?Now, besides from the point of me not knowing at all how to hook this up, I wonder if there would be a capacitor that would store enough power to light the bulb for a reasonable amount of time, if say, I used a 60 watt bulb. Then of course, I have a few questions, some of which I may of already said:How big would the capacitor have to be hold enough power to light the bulb up?How many hours (or minutes, if applicable) of moderate riding would it take to store enough power to light the bulb enough to see for about 15 minutes?Would the power stay in the capacitor so that I could charge the bulb a bit over the course of a few days?How would I hook such a circuit up?Could I hook the circuit up so that the power is stored from the wheel going around, rather than my pedaling?Thanks for any and all help, and if this turns out all right, then I may just put an Instructable up. I guess I'll have to see. Thanks again!

do it yourself 4 wheel adult sized pedal bike car

In spring I got idea to build a 4 wheel pedal car for my son. To use wheels from old bicycles, to make it as small and light and simple as possible and to make it possible to fit even an adult person. I was really disapointed surfing internet, as I found almost no free ideas, plans or experiences how to do it. It is no nuclear science, people would invest millions in their know-how, so they would need to hide it! Now it's autumn now and our car is done. I decided to share my experiences and detailed photos as free plans with other people, interested in self buliding pedal car of that kind. I wanted my 9 years old son to learn basics of construction and working with metal and wood. He did almost all hand works by himself and he is very proud on it. It is a very good way to move your child from TV and computer games! It is all on our 4 wheel pedal bike car web site

Wiring question?

Hi everyone. Long time visitor of Instructables, made a few items I've seen and my most recent project was adding a star power pedal to my guitar hero controller. I bought a audio extension cable with a male and female jack, 1/8th size. I cut the cable about six inches from the female end. I stripped about an inch, inside was a bundle of copper wire wrapped around a clear insulted wire. I twisted the exposed copper wire and tinned it, I stripped the clear housing and twisted it, tinning them as well. I tinned the exposed wire to the GND, and the clear to Select. Positioned the jack and everything went well. I took the male cable, connected it to momentary switch and connected the male cable to the female jack. Turned on the system and controller. Got star power and hit the switch with no response. I'm very confident in my soldering and know I did it correctly, so I was wondering: 1) Are these kind of cables capable of doing what I intend? 2) Maybe the GND or the Select button are shorted out on the board of the controller? Thanks for any help everyone!

pedal powered tractor

I'm no designer but here's an idea I've been stewing on for some time. I've hunted but not found any designs for a pedal powered tractor. The very early tractors were very large;could to lots of work; but they only had 2 or 3 horsepower. They ran so slow you could count the piston strokes. The designs were simple and they were work horses. Our new high horse powered gas tools often cann't do nearly as much. The old machines used heavy flywheels; slow to start but they kept on rolling. With the improvements we've made in bike gearing systems why not make a pedal powered tractor that could do serious work with that same heavy flywheel technology?

using a strain gauge to make a load sensing pedal

Guys, I want to use a strain gauge as a load cell in a driving game, where the brake padal is force sensitive not movement sensitive. Currently the pedal is set up with a rotary potentiometer which has three connections and is basically the same as a PC joystick, complete with the circuit board. The strain gauge is one of the resistive film type with two connections, and the resistance will vary with the extension of the gauge; however, I don't know how to link this to the joystick circuit hardware, as one of the connections is missing Any ideas?

Resistance Isn't So Futile

Nissan has introduced the Eco Pedal, an acceleration pedal that pushes back on the driver's foot if the driver is supplying unnecessary pressure and therefore being fuel inefficient. From Wired News: Nissan estimates that the Eco Pedal, coupled with the already ubiquitous instant fuel readout on the dash, can increase fuel economy 10 to 15 percent.While it may hinder driving freedom a little bit, it seems more like it's there to be a friendly little reminder. Sort of like parents when you're learning how to drive. Very environmentally friendly, fuel optimizing parents. Nissan via Wired News

"Organ donors"... or: sources for tube project parts...

The "Vacuum Tube" group needs a first forum topic. Here it is... Sorry 'bout the pun... but I could have used Time to get Organized... Be thankful ;-)Vacuum tubes and parts tend to be rather expensive these days. But there's a good source for parts, and it's often free: old tube organs.I picked up a working 1960 Wurlitzer a couple days ago. It's got:-- full complement of tubes (the mother lode!), including9 (nine!) 12AX7 preamp tubes.2 6L6-GC power tubes1 5U4-GB rectifier(there were other tubes: (28!) 12fq8's but they're not so useful for audio...)-- Huge power transformer-- Large (20-25 watt) output tranformer-- two 16 ohm speakers-- lots of carbon-comp resistors, sockets and other reusables.Total cost--just gas, and a sore back.Even the non-tube organs are a good source of speakers, reverb tanks, pedals, etc. The tank, bass pedals and the volume pedal were from a solid-state Conn organ left on the curb...The bass pedals could be made into a MIDI project, and the volume pedal would be a nice start of a wah, or left as-is. Yeah, they are grungy, but that's easy to fix....

elliptical bike?

Has anyone ever heard of an elliptical bicycle? I came up with a design that would pedal using the walking motion of an elliptical trainer and you could stand up or sit down. I recently have seen a video from Maker faire and caught a glimpse of a bike with a similar design. Some minor differences included: The use of a chain ( I think that might give more room to walk/pedal opposed to my design with no chain), the pedaling is higher, and it looks more sturdy. This is helping me produce a better design. A glimpse at the other design is around 7:00 to 8:00 in this video. I hope someone has heard of it.

Reducing current to drill

Hey everyone. I'm building a potters wheel for my girlfriend for Christmas, and for the motor I'm using a corded drill. I want to use something like a sewing pedal to control the speed, rather than the trigger of the drill. I've looked it up (on here) and it sounds easy enough, but the problem is that most corded drills are 4 amps and over, and the highest amperage I've found on a sewing pedal is 1.5A, I'm assuming this would blow up the pedal. Is there some way I could use a resistor to reduce the current drawn by the drill? Would the drill still operate on 1/3 the current? It won't need even close to full power. Where would this resistor go? Thanks in advance.

Guitar Amp Static

Following up on my other thread with soldering, I managed to get my circuit for a distortion pedal all wired up.  I've got the clean end working, and nothing at all on the distorted end, but I'm not concerned about that just yet.  On the clean end, I get a really annoying buzzing sound, like when you turn the amp on with a cable plugged in with no guitar on the other end.  What would be cause of this?  Possibly outside interference since I haven't actually put this into an enclosure yet?  This is the schematic I followed.. https://www.instructables.com/id/Simple-overdrive-effect-pedal/step2/The-schematic/ and the sound from my amp is similar to this.. http://www.youtube.com/watch?v=ZUeRLC4z8f4 No, it's not the amp that's the problem because it works fine without the circuit.

Help Making Tattoo Lab Power Supply Jumper / Converter + pic

This is what I'm talking about. can you see it?  it's the first thing that comes up on google image search when you type in "lab supply jumper." It's so you can plug in a tattoo machine and foot pedal into a lab power supply.  theoretically I get how it's working.  The foot pedal is what interrupts the circut.  when you press the pedal down, it makes contact and completes the circuit.  So, the machine needs to be routed through the pedal before getting power from the power supply (versus plugging the machine directly into the PS itself.  Cause then you'd have to turn the PS on and off to get the machine to work or turn off). So, I'm assuming that's why there is a cord going from the "machine" 1/4 terminal to the "foot pedal" 1/4 term, right?  Then the pos and neg banana plugs go into the power supply. specifically, my question is this:  do I have to solder to make this?  or can I just twist wires together?  and can I buy everything I need from radio shack, right?  I'm pretty confident I can do it either way, just need a diagram or something on how to wire everything. I'm also asking my brother who was an electrician before getting injured on the job- he's on disability now but may be able to help, too. =) It's gotta be easy to make, right?!?!  so help me do eeettt!!!  =0) thanks for any and all help!  Sarah ps- I attached a pic of the power supply I have so you can see it as well. and for the record, my tattoo machine is RCA not clipcoard, but goes to a 1/4 male mono all the same.  As well as my pedal. k, thanks. ;0)

Distortion pedal project

Ceramic disk?3) The plans call for a 0.0056uF capacitor yet I couldn't find one like that, can I just substitute one similar? If so, which one?4) If anyone wouldn't mind, could someone explain how this circuit works? Preferably answer the other questions, but I would like to learn how it works also.Thanks a lot to all who answer!

DIY Steering Wheel

Hello, I'm new here. So, lately, I've been thinking about making a steering wheel for my PC, with a simple up-and-down gear box and 2 pedals for acceleration and brake. Steering Wheel. I'm using a polystyrene sheet, to cut out a wheel from it, and in the center, there's space for installing a phone holder. I'm planning to use my phone's gyroscope and simulate it to the PC. Pedals. I've figured by using foams underneath, we can place a nail and a foil separated and when we press the pedal, the foil touches the nail and circuit gets completed. I've a general idea, but I'm stuck on how to give that signal to PC as to simulate as a button (say for acceleration and brakes.) Gearbox. For the gearbox, I figured it might be easier to make an up-down box (as in pulling the level shifts the gear up and vice-versa.) Here too, The part where I'm stuck is giving the signal to the PC. Anyone who can help me, please?

Magnetic switch to USB?

Hi, 1st post hope you can help! I'm trying to find a way of getting analog data (from an exercise bike) and store it onto a computer in a text file so I can manipulate it and work out averages etc. I thought of having a magnetic switch on the pedal so that everytime the pedal rotates I can store the time thus giving me the speed. Does anyone know if such a cable already exists or if not how to go about creating one? Also if anyone has a better way of getting the data I'd love to hear from you. Many thanks Adam

Excercise car?

What I am designing (and planning on working on very soon) is a vehicle with the possible speed of a gokart, but with a propulsion system similar to a bike. The mechanism itself would be a simple push pedal (like a car) but with a gear system like a bicycle. Upon pushing down the pedal, a shaft connected too it would then push against the foremost gear. and that gear would push another and so on until it comes in contact with the rear wheel, propelling it forward. A simple spring between the pedal and floor will allow the pedal to return to the original position. However I cannot seem to get the steering and brake system down right. Should the steering be that of a car and use 2 wheels on the front with a long axel connecting the 2? or more like a bike, with a one wheel turning system. (aka. should it be a 4 wheel or 3 wheel? Might depend on weight distribution and balance, though both could be possible.) and how should the brakes be arranged? a pedal, like a normal car brake, or a stick beside the driver, like an emergency break, as well as where the brake pad would come into contact with the rear. On the axel or on the wheels? Last (and most definitely not the least) is that while this vehicle must be sturdy, it must also be light weight. So any and all material recommendations for parts would be greatly appreciated. (cheap would also be appreciated) (My thought for material) chasis - light, but firm (strong) wood. axels - aluminum or steel tires - Gokart/ riding lawn mower turning wheel/steering - wood or plastic seat - whatever I can find that's soft (not a major thing) safty belt - I may not be able to test out the prototype (kinda thick) so I need the crash test dum *ahem* "driver" to survive incase a crash were to happen. brake pad - rubber so that it causes the right amount of friction but not enough to damage any parts.

Question about converting a 9v Battery Gadget to AA's.

Hi. I have a Boss DS-2 distortion pedal, but my problem is, it drains the 9 volt batteries like a semi-trailer. So I basically wanted to convert it to AA batteries. Technically speaking, I'll need 6 AA's to make 9volts, but 9 volt batteries have a different current don't they, or will that not matter in this application. I'd also like to insert an on/off switch because it drives me crazy that the only way to remove it, is by pulling out the 'input' cord (guitar to pedal). Please respond if you know the answer.
