Any suggested uses for a screwed mouse circuit board? ~Edit: make that 2 (one digital, one ball)~

I have a circuit board from a mouse that has gone to a better place. Any suggestions for what I can do with the bloody thing? At the moment it is just taking up space in my drawer and any help would be... well... helpful.

Does anyone know if the facilitator of mintyamps.com is ever planning to reopen the site to orders?

I really want to make one of the circuits and I have very little electronics knowledge.  Are there any alternative circuit boards I could order that serve the same function as the minty amp? Cheers, Dean

Identifying Sliders and Knobs on circuit board M-audio Axiom 49

Hello there, I broke 4 of my sliders of my M-audio Axiom 49 and bended 5 Precision rotary knobs. I tried to order new parts at M-audio but they discontinued the production of the 1ste generation of M-audio Axiom 49 keyboard controllers and they cannot deliver the goods. So opened this sucker up and just googled Pots B10k and to my amazement I found a website with all these Precision Potentiometers. http://www.mouser.com/Search/Refine.aspx?FS=TRUE&N;=4294759271+16330845+1323043 http://http://www.alibaba.com/catalogs/--400502------------351-4333 I mean 1000, I went looking for what I needed. The only problem is everything looks the same, I don't see any part numbers that could identify the parts on my board. So I was thinking I should ask some one who has and eye for this and is much smarter than me :) Can you help me identify the type of Precision Potentiometers on the boards you see on the pictures I posted.-->(sorry for the bad quality)

Rewiring a boombox headphone output to be an Ipod input?

I'm rewiring an old boombox to be able to play music from an ipod. Since it doesn't have an input anywhere on it, I've decided to rewire the headphone output to act as an input for my ipod. I've already gutted the tape player. The headphone out is attached to a circuit board which then connects to the main board, which sends the music to the speakers. I will change the old headphone input wiring to go to the old tape input(same wires). The only problem I can forsee is the circuit board which connects the headphone jack to the wires. Will it keep trying to send music out, or will it let the Ipod's music pass back into the main board? Connection diagram: Ipod -> Double-male audio cable -> Headphone jack -> Circuit Board -> 6 Black wires -> Main board's tape player input -> Speaker

I need help moving some buttons on a GameBoy Color. Answered

I have been working on a modification to a GameBoy Color.  I am basically putting it into another case that I have custom designed for the project.  I was just wondering, is it possible to break off a part of a circuit board and connect it with wires? I basically just want to move the "A" and "B" buttons 1/2 inch to the right to make them fit in the case better.  I think that will be easier than designing button extensions or something like that. I included an image to show the board and how the parts are labeled.  It is pretty easy to figure out what portion is what button (thanks Nintendo). An example of a similar idea can be seen here:  Ben Heck's Portable PS1 (It is a little past halfway down the page, where he shows how the inside was wired.  From what I can tell, he broke his PS1 controller into sections.)

Is there a circuit board or FX module that mimics a Fender tremolo system that can be installed on the guitar itself?

I'm not referring to the amplifier-type Tremolo's as in Fender Amps, but a device that takes the mechanics out of a traditional tremolo set-up and digitizes the signal to do exactly what a Fender-Style Tremolo on the guitar does. In other word's, I would like to design a module or device that act's and performs by using the Tremolo Arm, as in slang term's, DiveBombs, Diving Harmonics or just about anything you can do with the mechanical Tremolo Arm itself. I've really been researching this, but so far no luck. Any info will be deeply appreciated...Thanks..Wayne6412

Household Appliance Efficiency (Slowing the meter)

Hello, Does anyone have an idea how I can build a device or circuit board that I can hook up a computer  to monitor the efficiency of Appliance and hopefully write a computer programe to maximize the efficiency of the appliance and minimize the power drawn from the power grid. Basically slowing down the meter while the appliances still operate at their full potential? Thanks

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

Which capacitor is the sweep cap in a Cry Baby GCB-95?

I have a Cry Baby that I want to mod into a bass pedal, and I've heard that you can simply replace the sweep cap with a .068 uF cap to make it a bass wah. However, I can't seem to find the sweep cap, the only capacitors that I can see have the wrong value, but there's these weird box things that I'm not sure about, I've never seen a capacitor like that before... Anyways, could someone please tell me which capacitor is the sweep cap? It says it's a Rev. H model on the back plate, but the circuit board says it's a Rev. I, if that helps.

Illuminated bed

Ok I'm really kind of new to electronics but I'm going to throw out an idea and if anyone could help me with this I would be greatly appreciative. I'm building a platform bed and I saw this picture when looking for ideas I instantly fell in love with this lighting. BedBut here is what I was thinking, what if I do my room in a different color? How could I make it look good? Then I thought RGB. Now what Im thinking is using Red Green and Blue Led's each I would imagine each would have to be on a different circuit and hook into some type of controller that can modify which one is brighter. I would think there would be some type of board I could hook up via usb and some software to change values of light. So if anyone has suggestions on what size LED's, resistors, or what kind of board I would need Please let me know I really am lost as to where to start. Also about how many would i need of each to have a good glow like this if its any help Im going to be using a queen size mattressBed

OK, Let's clarify some things....

1) OK, I will clarify this after it confused me for so much time. For those of you who didn't know,Eric and canida are marriedI tell you this to help you avoid all the stuff I went through. I saw a lot of things that pointed towards this fact, but nothing actually confirmed it. I didn't have the courage to ask here, if I was wrong, the embarrassment would be too much.... So there.What happened to Stasterisk?Star Simpson is a girl that strapped a fake bomb to her and tried to go through an airport. It was a circuit board with play doh attached to it in certain spots. She is currently a student at MIT, which explains the website url. So if you want to get more of an idea of who this Star Simpson girl is. Check outthis pageAnd this ibles postMy name is BryantAlthough, I think Gorillazmiko made that quite clear. Get over it.

Help re-building/modding my bass guitar with an old tube amp i want to salvage parts from?

Right so I have this bass guitar with most of the electrics missing, I'm only left with the jack out and the humbucker pickup. I want to do something a bit different as i have fixed guitars before and as this one is actually mine i want to experiment with it. I also have 2 old guitar tube amps with a "Speed" effect on them which makes it sound like the speaker is pulsing, one of the amps now doesn't work, I'm presuming and hoping it's the just the tubes or power input and i was wondering if there was any way i could put the "Speed" effect into the bass. I'd also like to salvage the treble and bass pots too if it's possible.The speed effect is controlled by a pot that when turned all the way down clicks and turns off, i have opened it up to try already but I've only ever really done basic electrical repairs and this is connected to a proper circuit board. I can send more photos to help.Thanks in advanceel GinjoelGinjo@live.co.uk

I won!

I posted this topic before, but I don't think anybody saw it (instructables glitch?)From wendsday to saterday i went to a resort named 7 springs in champion, Pennsylvania. I was there for a national competition called technology student association (aka TSA). This competition was states, for I already went to regionals.I won 1st place in Electrical Applications, which is basically your knowledge of electronics (you take a test) and you have to create a circuit on a bread board, along with creating a schematic. I tell you, this was almost a joke. Questions on the test are like --| C---- what is that a symbol of? And what does IC stand for?The breadboard challenge was even easier. They gave you a breadboard, a 9 volt battery, a lightbulb, and some wires. The challenge was to make a circuit (and schematic) that light up the lightbulb whenever you touch the probes to the right spots. Like you know those question and answer things at science fairs where if you line up the right question with the right answer? That's basically it.I also won 1st place along with a couple of my friends for a medical challenge where we gave a presentation on alzheimer's disease. Not much to explainMe and my friends also won 3rd in another thing, I can't remember (I get my trophy on wensday because they didn't have enough trophies for the whol group). I think it was in agriculture and biotech where we talked about biofuels.Me and my friend got 6th in a challenge where they give you a random technology topic and they give you 10 minutes to prepare (no computers) and then you have to give a speach.Me and my friends got 10th in a thing called tech bowl where they give your random questions and you are in direct competition wire people nexy to you (you have a buzzer).Me and my friends got 9th place in a challenge where we talked about the enviroment (specificaly ozone depletion);)does anybody know where this came from, I'm pretty sure I saw it at TSA (I just remember a yellow wrapped transformer at an angle in a box with a phone and it's all in a box)http://blog.makezine.com/archive/2008/04/send_an_sms_to_save_your.html#comments.

recording photo frame mod to mini amp/speakers

I bought a little recording photo frame at Walmart tonight for $2.88. Sadly someone had been testing it and the batteries are dead, so I can't check the volume til I can get new ones. What I'm wondering is whether anyone had altered one of these or something similar to make it mini amp w/speaker. I'm wanting to install something like this in some small stringed instruments(dulcimers) I'm making that don;t have much volume on their own. I've looked at all the altoid ideas and mini amps and mini speakers, but didn't see anything that would do what I need. Most were just for ipods. I did see one that used a spy ear and that's what gave me the idea for this. I have one of the cheap little clear plastic spy ears somewhere, but couldn't find it tonight I would be ok for picking up the sound, but I don;t think mounting the earphones on the instrument would give enough sound. The soundbox on my larger. dulcimers did ampllfy some earphones I got at Dollar Tree, but not much. I would add pics of the circuit board of this recorder, but my camera is dead. I would really appreciate any help with this. I need to keep the cost down as much as possible in order to keep the dulcimers affordable. The ones I am making are more a novelty item, so I can't price them too high.

Need Party Ideas...

As many of you might remember, on 1/31/07 a terrorist group, in a coordinated attack against the people of this great nation, attached devices that contained circuitboards, flashing lights, and batteries to buildings and bridges in 12 major cities across the US. In 11 of these cities, the devices were largely ignored and people went on about their business as usual. But in Boston, someone decided that a circuit board with some lights in the shape of a cartoon character must be a bomb. The city was quickly shut down as they closed the subway, bus system, and several bridges and building were evacuated. The city was in a state of panic! Was this another 9/11? Were these sinister devices really dirty bombs meant to kill innocent civilians? By the end of the day, Boston had spent over $1,000,000 (yes, i said million) dealing with the devices. Who could have launched such an attack on American soil- Al Quada? the Taliban? North Korea? nope... Turner Broadcasting Group. They paid 2 artists $300 each to make what ammounted to a childrens toy known as a Light Bright to be used as guerilla marketing for the upcoming Aqua Teen Hunger Force movie. Rather than admit that they overreacted, the city of Boston sued TBC for $1 million in restitution and another $1 million in good faith money. The two artists who only did what they were paid by TBC to do, were forced to do a combined 140 hours of community service. I'm having an Aqua Teen Hunger Force marathon on the evening of 1/31/08 as a memorial to the freedom that we as a nation have given up in the 2000's. Americans as a whole have a hard time understanding that the terrorist do not intend to kill each and every one of us with bombs and plane hijackings. They seek to control us through fear. The city of Boston was so afraid that they completely shut down the city because of a lightbright hung on an overpass! Sad as it is, the events of 1/31/07 are an indication that the "war on terror" is a losing one. http://www.youtube.com/watch?v=7kdP8WBB4lI I said all that to say this: I'm looking for some ideas for my ATHF marathon party. I'm working on a lighted 'mooninite' for the front yard, and I know I want to incorperate the governments 'terror scale' (you know the color thing) somehow. I am also asking each guest to bring one harmless-yet-contraband item that I can confiscate at the front door much like the airport security. If you have any idea for other tasteless things for the party lets hear them. The less P.C., the better!

How do I actually PROGRAM a z80, 8088, 8035, or their predecessors? (schematic, code, assemblers, UVeproms?)? Answered

I have a z80, apparently, with supporting ICs, on a PCB waiting to be salvaged. All I could find online for z80 programming was this guy who was making a whole computer out of it. And a lame "z80 world" site that doesn't help me. Also, on a separate board, I have a couple of Toshiba TMP8035P (with UVeprom nearby), whose online "datasheet" says that it's instruction set and pin compatible with the intel 8048.see:http://www.atarihq.com/danb/files/8048.txtand:http://download.theicstock.com/TMP/359/TMP8035P_1541359.pdfI have programmed microcontrollers before, so I know a tiny bit of what is needed for programming them. (Note: modern microcontrollers, in basic-esque languages, notably picaxes and basic stamps)My problem is in how to actually make the program on my computer, press the download button, and the chip run the program. I have no idea how to do assembly, (or find the right assembler). I am also clueless as to hook the computer up to the chip. (I suspect it requires a parallel port, but I think I only have DB9-pin serial easily available. I do have a single parallel port in a win98 computer, but it would be a pain in the butt.)In addition, I don't have a UVeprom eraser light. (I have an uncle who does, but I only meet him every now and then. Maybe he would let me borrow it?)Another problem is, I'm on a time limit. It does not have to be done tommorrow, but if I do not clear the garage of my currently un-programmable outdated microcontrollers soon, I will be too busy with college this fall of 2009 to work on those things, and my parents will force me to throw them away.As for the 8035's my uncle also needs room in his garage, and if I can't program mine soon, then he will throw away his remaining stash of them. (No sense in holding on to equipment your nephew can't program in a timely fashion)By the way, the same uncle dumped a CMX controller on me, with a weird keyboard, huge scroll wheel mouse, and the big box with computer-like guts inside, and a gazillion I/O ports on the back. He said it could be programmed, but Wikipedia said the company that made this video-editing machine went bankrupt or something. If I had the "instruction set", I assume assembly, in addition to a download circuit, then I can use this thing for controlling lots of cool things.Oh, and my uncle is very nice to me, so don't think I don't like him just because his hobby is dumping old junk on me.PS: I'm just whining, but it seems all these old microcontrollers, equipment and whatnot assume I grew up with these. I didn't, so anything beyond plugging in a basic program to a picaxe is rocket science to me. (No, I'm not Russian)
