Arduino Guitar Tuner

Hi everybody, I'm creating a simple guitar tuner for a project at university. The purpose is just to create a step-by-step guide to it's creation to demonstrate some processes in how they work. Obviously it's going to be more expensive to make than to buy one (unless you happen to own a Taiwanese factory) but it's more about demonstrating some basic electronic principles and providing a basic design and seeing if it evolves with user input. So this is just a general enquiry into community interest. Comments and ideas welcomed. Cheers

A guitar question: The Turny thing on my guitars tuner fell off. Answered

The actual tuner is still there, but i cant use it to tune only to hold the string.  Im wondering if theres a way i could get the part back on or build another part. Ive thought about sodering but i didnt think that would be enough to hold it. I found the thing that you turn ,but, sadly lost it again cleaning up for a party. I really like this guitar but do not want to spend the $$$ to buy new tuners. If it makes a difference its a carvar les paul style guitar.

How can I identify re-used electronic components? I need help with a guitar amplifier circuit as well. Answered

Hi, I want to make an amplifier based on the schematic in this instructable https://www.instructables.com/id/Make-a-Sweet-Portable-Guitar-Amp/. I wanted to add a power input jack so I left a comment on the instructable and the 'ibler replied and told me how to do that. Now I am considering more possibilities, firstly, could I incorporate an led tuner? If so would it be best to just take a tuner apart and use that, could it share the same battery and mono guitar input jack? Recently I took apart a cd player and salvaged two nice speakers, but they don't say how many watts they are they just say "QS" then "8Ω" and "5V". I don't think they will be suitable for this project anyway because they are 5v and I'm sure this circuit requires lower output voltages than that but i just thought i'd check. A label on the cd player said the power consumption for the device was 15W, can you work out the power of one of the speakers from any of this? Bearing in mind there were two speakers in total. Another question, if I want to reuse resistors I know how to figure out their resistance using the colour bands and a resistance calculator etc. But is there a way of identifying what is a 1/4 watt resistor and what is a 1/2 watt resistor.

How to I make an AM Antenna?

I was recently given a "Tuner" set up ( one of those boxes that you plug TV, DVD, speakers, CD, and VCR, into and has a built in FM /AM tuners)The Tuner has ports in the back to plug in wires for FM antenna and AM Antenna. ( 2 wire accepting ports per band ) How do I make antennas to plug in to the back of a radio tuner with just wires? Do I need to put in other components? What other components might I need, where do I find them, and how EXACTLY do I incorporate them?I tried to follow the Instructable https://www.instructables.com/id/Medium_Wave_AM_broadcast_band_resonant_loop_antenn/ I ran the two wires into the back of the Tuner instead of a "polyvaricon" (plastic insulated variable tuning capacitor) because the Instructable, as it is written, does not provide for plugging the Antenna into anything.I Used a 12ft length of CAT5 ethernet cable to create 8 loops of insulated wire as described in the Instructable but still can not get very good signal on local AM Stations that are less than 20 Miles away.

DIY DVR (PVR ?)

No, not the mythTV variety, but the real deal. I've been messing with uCLinux on various chip, which led to a vague daydream that I sketched out on the train today. These are my notes on a personal DVR. I say personal because its design for MY needs, and not the typical user. It also happens that no commercial DVR will meet these specs without being mired in lawsuits (see replayTV). Why an embedded solution and not MythTV? I've had mythtv boxes, they can be a lot of fun, and a lot of frustration. Mostly, I don't have room for a second computer, I don't want to use a ton of energy to record a few programs, and no matter where it ends up in my apartment, I will be able to hear it at night. MyDVR: I already watch all my TV on the computer. Either by TV tuner or Xvid. I don't need a Tivo style DVR that will play back content on a TV with a nice menu display. I need a mass storage device that records TV shows. I want Xvid. MPEG2 is huge. Its also kinda ugly. I really really like the look of the XVID codec. It takes a reasonable amount of space for a decent encode (~178 meg per ~20 minutes HDTV). I want multiple tuners...I mean, what if there are two (or five) programs to record simultaneously? Basic design: A motherboard with 32 bit CPU running uClinux (probably a chip from Freescale). These usually have USB and an ethernet MAC (but no PHY). USB 2.0 mass storage device emulation on the USB port. This way the unit can be hooked up to a PC for easy video extraction. This might also have some configuration abilities, but that would require a custom mass storage controller driver - YUCK! Ethernet with HTTP server for show scheduling. IDE interface to a big hard drive. The tuners and encoders would be on add-in cards. The add-in cards would have: 1. A tv tuner. 2. A DSP with xvid encoding. 3. Probably a small uC to control the DSP and tuner. Whats already in my knowledge domain (stuff that I already know about -or- could I really do it?): 1. I've been messing with uClinux for a while. What fun. 2. USB mass storage controller implementations are numerous. check. 3. Embedded HTTP server - check. But I have not routed a PCB using an external PHY. This looks messy. Perhaps a ENC28J60 instead? 4. I've been reading up on some XVID DSP implementations. There are also some commercial MP4 chips, but I bet they're pricey! 5. I picked up a bare PAL tuner at the surplus shop. Time to play. There are a few things that make this project easier than a Tivo clone. There is no video output. No need to do fancy display overlays synced to the incoming/decoding video stream. This is encode only - no need to load, decode, and display the XVID. I'm kinda testing the waters on this project. I'm going to get some DSPs and try to do real-time XVID compression. Also, I need to figure out the tuner card. Any suggestions within the scope of this project would be awesome! Especially if you've worked with uClinux and have a processor recommendation.

Why does my LM386N-1 amplifier chip get hot when using mp3 player as input, but is fine when guitar is the input source? Answered

I made the amplifier in this instructable https://www.instructables.com/id/Make-a-Sweet-Portable-Guitar-Amp/ and it is currently in breadboard stage. I had a few problems after adapting the circuit to have a switched dc input jack as well as battery. But after some trouble shooting i fixed these errors. I ran it off battery and dc input (9v) wall adapter (a universal 500mA regulated ac/dc transformer set to 9V) with a guitar as the input and it worked fine (as far as i know). Then as it said in the instructable that you could use it with and ipod or mp3 input too, i thought i'd try it and see what it was like. I used the dc input adapter when i did this and plugged in my mp3 into the input jack using a 3.5mm to 1/4" adapter. Then when i swithced on the circuit i didn't hear my music through the speaker, just a bit of hum and then i smelled a slight electrical burny smell so i turned off the power as quickly as i could. Then i felt around and it was the lm386n-1 chip that was getting hot. Firstly can anybody diagnose the problem? Secondly, is it likely to have permanently damaged my chip? Thirdly, do you think it will be because of the power source not being a battery? I don't think so, it worked fine with both with guitar input. But i suppose it could be related to that

Air Traffic Control on PC

Air Traffic control broadcasts from 108 - 138 MHz. (https://www.instructables.com/id/Transistor-Radio-Hack/)A couple of months ago I bought a Realistic Jetstream radio. It was used. I saw it there before. I finally bought it. I thought it was just an FM/AM radio. It said AM/VHF. I thought that was odd. After I bought it I realized that it wasn't an FM radio, it was an Air Traffic Control scanner! That was even better. It comes apart just like the radio Kipkay used in the hack. It was already an ATC radio though. My question is there any way to get Air Traffic Control on your computer? I tried an old tv tuner card. I set the frequency to 122.8MHz. That is the frequency for the local airport in Microsoft Flight Simulator 2004: A Centruy of Flight. It is also what my radio picks up. The antenna won't pick it up on the tuner. FM radio works though. I hope all this makes sense.

Computer as composite display device

Hi, Okay, here is my problem: I found in my garage a small video camera (not with tape, recording or anything, it just plugs directly into the tv to watch the area) which I had got some years ago, now I would like to start using it again, however I don't think the only tv in the house is a good monitor (it doesn't provide any recording and it already has all rca inputs in use). What I would like to do is connect it to my pc and view the video (and listen to audio) on my computer, then like this I can also record video to the HDD if necessary. The camera has a composite video output and a mono audio output. Thanks, All help is appreciated. P.S. The problem with TV tuner cards is that I already have one, but it is not with me so I can not use it, on the other hand since I do already HAVE one I am not going to buy another one. Damn it when I thought that tuner card was not going to be useful and decided not to take it with me.

Nanotube Radio

Nanotube Radio: Supplementary materialsK. Jensen, J. Weldon, H. Garcia, and A. ZettlDepartment of Physics, University of California at BerkeleyCenter of Integrated Nanomechanical Systems, University of California at BerkeleyMaterials Sciences Division, Lawrence Berkeley National LaboratoryBerkeley, CA 94720, U.S.A.We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. Moreover, the antenna and tuner are implemented in a radically different manner than traditional radios, receiving signals via high frequency mechanical vibrations of the nanotube rather than through traditional electrical means. We have already used the nanotube radio to receive and play music from FM radio transmissions such as Layla by Eric Clapton (Derek and the Dominos) and the Beach Boy's Good Vibrations. The nanotube radio's extremely small size could enable radical new applications such as radio controlled devices small enough to exist in the human bloodstream, or simply smaller, cheaper, and more efficient wireless devices such as cellular phones....This is the site of the original article
