I was just wondering if anyone could help me in thinking of a way of modifying a keyboard so that you could strap it to your back without damaging the keyboard in the process and then put addons onto the strap. The reason I want to do this is because I need something defining for my personality that will show my love of technology, and I also want to take my keyboard with me to places.

2 questions about transformers: - If a certain transformer (let's say, for a power amplifier) is needed, and for example, a microwave transformer is available, can the steel frame be cut to take out the secondary coil, to be replaced by a new one, and subsequently be re-attached (by clamps or so)? Would it need some treatment, like putting varnish, or oil over it?  Would this cutting and re- attaching cause a loss in efficiency, or cause heat build-up? Would it cause more noise in the output? - Some amps have a toroid transformer. Is this just fashionable or is it for a reason? Some industrial amps use sheets of copper instead of wire. Why is this better for industrial, why, and if not for common stuff...?

Hi, I have a Yaggi style tv aerial (vertical polarisation, wideband) in the loft I pick up the main signals from a sub-transmitter (forgotten the right word) to the front of the aerial - good reception. I receive some weak signals, depending upon the weather conditions, from the main transmitter at the rear of the aerial. I receive these signals by reflections from the landscape, etc. I am thinking of attempting to boost the reception from the rear by placing horizontal directors alongside the vertical directors. Do you think this idea will increase, decrease, or make little difference to the reflected/direct receptions. Thanks A PS.  Before you ask, Yes I have tried pointing the aerial towards the main transmitter, but I get no signals, due to geographical considerations. I get better reception from the main transmitter when the aerial points 90 degreesaway from it.

Ya is it possible to covert a crappy spring airsoft gun into a good CO2 powered airsoft gun and if there is how thanks

Some people may know about a toy called Mr. Bacon. It is a toy race pig. One of the best things you can do with it is modify it. Post your modified Mr. Bacon pig pix here. You can buy it from www.wackyplanet.com/mrbacon.html

Would it be possible to modify a cricut machine's cartrige so that you could download multiple cartridge's data and use it? it looks pretty simple, but I would have no idea.

I was wondering if anyone has ideas if and how I could convert Airsoft, Nerf, etc. into a more realistic water gun. I was thinking some ideas of being able to shoot these guns, with red dyed water, without a need to wear face or body protection. Magazines could be the storage of the water, and lower fps so, as my main point, was to not wear protective gear. If anyone knows anything, or a website I missed, I have searched everywhere and found only water guns to Airsoft. Thank you for your help.

Is it possible to distort, amplify, or otherwise modify sound using an Arduino in real-time? I was thinking of making a voice modulator that I connect my microphone to in order to change my voice. Quality isn't an issue, I just wondered if it was possible.

Hello, I just thought I'd share the last few months of completed work with my fellow makers! I'm addicted to modifying and painting Nerf guns now because its something you put a lot of time into that is used regularly. It doesn't gather dust or become a paper weight like my previous model car hobby.  Anyway enjoy, and thanks for looking! More pictures can be provided if you're interested. JonnyBGood

Is it possible to modify your phone or phone buzzer so it will vibrate a lot stronger as seen in this clip (skip the first 10 seconds).

I've just posted an update to my Double Barrel Shotfun Instructable - an ammunition modification! Go see the all-new Step 9. It's potentially very messy...

I was thinking, Is there any component that controlls the amount of electricity entering a laser diode? If there is can you replace/short circuit it inorder to make your laser more powerful and hopefully burning? thanks, Fidgety

I have here a cheap rc vehicle with foward//turn capability. Is there some way i can alter the controls to make it turn left and right? The front wheels arent restricted to left or right only, they turn freely in either direction but the remote only has a turn button. (Pics of front and back of remote just added. Some sort of switch activates each motor but the control is either on or off from what I can tell. Although from what I can see, simply adding a couple of switches with foward/reverse functions soldered directly to the board would do what I needed.)

I propose a modification of easily obtainable Styrofoam glider's allowing longer airtime VIA a small electric motor. To be successful, the modification must be light weight, cost effective and use minimal tools so smaller children (I think of myself as a big kid) can repeat.Before you go off on me for this not being an instructable - read this: https://www.instructables.com/id/EYD12YXN3XEP2873DL/ -- I'm going to try and breathe some life into the idea :PI'm thinking I'll find a personal fan (might be hard considering it's winter time :P) and start there. If I recall, those fans are directly driven and use one or 2 1.5v batteries. I think it can handle reverse polarity at 9v.I'll bore out a hole in the nosecone for the motor and hot glue it in place. If possible, I will place the 9v battery aft of the wings -- attempting to preserve the center of gravity.In the video below, when my buddy says "Test 2" that is the second test using his glider (after the fuselage cracked off on a hard impact). His wingspan was 12 inches shorter, and his glider was heavier. The video was recorded with an ATC 1000 helmet camera*** and hastily thrown together.*** I lost some footage -- on some impacts, the camera "froze" and the video did not save. I had to pull the batteries to get it going again. I suspect the memory card got jarred and the camera didn't know what to do with it. Or, something completely different. This only happened 3 times even though the "test 2" portion of the video was a vertical impact.Suggestions and Feedback welcome :)

Hey all. I've been modifying nerf blasters for about 2 years now, and would like to make my services availbable to everyone. From integrations to breeches, you can find it here. I'll be willing to modify the following (to a certain extent on some blasters): Nightfinder Maverick Big Bad Bow Longshot Recon Switchshot Airtech 2000 Titan Scout My contracts will consist of a blaster that you send (or the money FOR the blaster and service). I will then perform the modification and send it back to you. Or, we can discuss the type of blaster you're looking for, make it a suprise, THEN talk prices. http://s588.photobucket.com/albums/ss330/homasimpson/?action=view&current;=Movie.flv http://i588.photobucket.com/albums/ss330/homasimpson/CopyofCopyofNerfCrap005.jpg http://i588.photobucket.com/albums/ss330/homasimpson/Image-22.jpg http://i588.photobucket.com/albums/ss330/homasimpson/Image-19.jpg http://i588.photobucket.com/albums/ss330/homasimpson/IMG_5534.jpg http://i588.photobucket.com/albums/ss330/homasimpson/Image-1.jpg http://i588.photobucket.com/albums/ss330/homasimpson/Image.jpg Copy and paste those links into your browser, they're pictures but I don't know how to attatch them.

Ok my fellow creators I am asking for your help. CO2 project is making  portable air tools without lugging around air compressor. Have pipe work and connections already done and modified the CO2 adapter to puncture canister when screwed in to release air. The problem I am having is once I attach an air tool it work fine, but after I release trigger air keeps flowing through because of to much pressure. If I read correctly its about 100 psi. Thought about direct connect from tool to air but I would like to be able to switch out tools. Have air tool change connectors at end right now. I do have high pressure shut off valve. Its just trying to regulate air flow with amount of pressure this thing releases. To be honest eventualy may be weaponized. Thanx in advance for your input. 

We have a professionally installed burglar alarm system that dials out (over a dedicated landline) to a monitoring station when an intrusion is detected.  I'd like to modify it to send us an SMS (via the mobile phone network) and/or email (via wi-fi on a different landline) as well, just in case the phone line is cut, and to make sure we get notified immediately - the monitoring station tries to call on the landline first, then it calls our keyholders and the police, which all takes time.  If I'm 5 minutes away and the alarm is triggered, I'd like to know straight away so I can rush home. The alarm company have quoted a huge sum to make this change, because an updated control control panel would be needed to deal with the texting/emailing.  I can't go cutting into their system or it will invalidate the maintenance contract, so I need to pick up when the alarm is triggered without any physical connection.  Short of remotely detecting a current in the cable to the siren (a 12V DC signal, so how would I detect that?) it occurs to me that using Arduino to listen for the siren might be the best bet.  But I'm an Arduino beginner and I have no idea whether it would be better/easier to detect a noise over a certain threshold - the siren is very loud, but the noise from the adjacent road can be pretty loud too - or to try and detect the particular sound frequency of the siren.  All suggestions gratefully received. 

The first time I did this modification was about 10 years ago, and this is my second attempt. Both times it was done as a repair and not strictly as a modification. There are actually many advantages to a newly "rewired" mouse such as the mouse button being easier and more convenient to press.  (possibly an inexpensive and simple method to avoid carpal tunnel syndrome?) Anyway, the modification is located on one of my website pages: http://www.1728.org/mousemod.htm I've seen a lot of mouse modifications on the Internet and I doubt I was the first one to think of this. **************************************************************************** Edited to Add I finally uploaded a picture to this posting.

It gets 70 feet with a stephan

For christmas, i got a Ipod Classic 160 GB. But, when i checked the settings, there was only 148. There was pretty much nothing on there, so was that a design flaw, or what?

To keep a long story short, here is the problem I'm trying solve:  I'm in the process of moding  a Nerf N-Strike into  a coil gun.  My "ammo" for this are steel archery tips that measure 8mm in diameter.  Since I'm overseas right now and have to order the gun online, while I wait for it to show up, I'd like some input as to how I might increase the magazine's spring strength while narrowing the inside width of the magazine to accomodate the diameter of the of new round.  In the past I've tried small pieces of foam board and plexiglass, but that has a tendancy to get messy and cause too much friction.  I'm sure once I have the gun to look at and play with some "great idea" will come to me, but until them I'm stuck imagining.  Any help would be appreciated.

I have a surround sound speaker system that only takes the typical stereo wires (you know, positive and negative electrode inputs for left and right side). I also have a stereo reciever that only provides A/V outputs. I was pondering how I could make these work when I realized that, even with an A/V cord, it still needs to make a complete circuit. Thus the cord needs to have two wires going through it, and the plug had a way to complete that circuit. Now that I know this, I want to know if I can cut the plug off of one end, strip the wires apart, and plug those wire ends in my subwoofer? If anyone knows if this is possible, please let me know! And please help me determine which wires are positive and negative current. THANKS!

I can't get schematics for my walkabout 330 scooter cause not only do they not make them anymore but they never had electical schematics for them so i woul like to rewire it and by pass a lot of crap as i don't need lights horns chargers etc etc etc as i use it on the golf course i just want the simpest diagram that will suit my 24 volt two motor walkabout mobility scooter as it is as solid as a rock and too good to waste,can i bypass the circuit board  somebody surely can show me how to do this i don't know how to do a continuity test on the circuit board maybe that would help PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE  my email is maccasda@gmail.com   any help would prevent insanity

This forum is for pictuers only you can include the range and modifications if desired the pink yellow and white disc shot is my secondary and it gets 70 feet with a stefan the blue and white bbb is my primary and gets 120 feet with a stephan 

So i, like many others, have some strange obsession with Hidden Blades and really want one. However, i do not have the machines to make one from scratch like most of the walk thoughs on here, and since i do not have enough time at the moment, heres what i was wondering: Is there anyone out there with enough time, money, brains and skill to convert a shop bought hidden blade from spring loaded mechanism to the more realistic ring pull mechanism? I think it could potentially be quite a challenge, working around the already existing parts. I am talking about the blades on sites such as Forbidden Planet, and also i have found iconiccollectables.com selling them.

Hello,   I am working on a project and would like to know if you can assist me with a specific modification. I have a regular, medium size LED strobe light in which I need to increase the amount of times it flashes, so much that the human eye cannot detect the flashing. Please advise if you can help.    Thank you for your time and have a prosperous day,  

 What  modifications are needed to allow a semi-automatic pistol to fire blank ammo? The reason I ask is that on various film prop sites I have come across a photo of a gun, ( for an example see accompanying image), and the phrase,  "Note how the gun has clearly been blank converted." I can guess at the reasons but does anyone know? (Don't even bother trying to google this.. .you will get thousands of pages on how to convert a blank gun to fire real ammo.) This is from the film, Heat. Thank you.   

I got 2 Remote control Light Saber room lights for Christmas. http://unclemilton.com/star_wars_science/#/rc_lightsaber/ I want to mount them crossed, like a crest, but I want them to be operated independently. Both Remotes control both lights. I would like to be able to Change frequency? or something to make the remotes specific for the lights, so they can be changed/turned on and off independently. Any ideas?

I found a working pre-amp inside a turntable from the 60's. The turntable was scrapt, so I remove the pre-amp from inside. Now I want to put it inside a vintage radio wooden box, the problem I got, 5 potentiometers on the pre-amp, but I need to modify this so it will only have 2, becuz the radio box has only 2. I will use an iPad with this pre-amp, so there really no need for extra audio adjustments like treble or bass... So one for volume, the other for open and close. How do I modify the circuit of this pre-amp so there will be no sound problem ? Do I remplace the gradable resistors with a standard value resistor, if this is how to do it, what value should I use ? I've done some tests, if I skip the potentiometer and I'm getting too much static. I' would appreciate help on this! thank everyone !

Lately I've been looking for vacuum cleaner mods. I've done several Google searches and Instructables searches, and found only this one bag-to-bagless conversion. I expected there to be at least a handful of pages on vacuum cleaner modification on the Web. Does anybody have any suggestions on where to look?

Wouldn't it be cool if instructables paired up with Ikea for an Ikea mod contest !  Ikea - Swedish for super sweet!  It could be based on the most awesome use of Ikea items modded to another purpose or perhaps to increase its coolability, dunno.  just a thought

I want to add a USB port to my stereo system (Home Hi-Fi). I want to keep the CD drawer, so getting rid of that is a definate no-no. It also has two cassette decks, which i'd be more than happy to modify. I know the tech exists, but can't find any schematics for it (probably for a good reason, but still). Any help would be much appreciated Allyn ~ FreakWorx

I have figured out something useful without making the firefly ugly. First, take out all of the screws, and start mapping them by the nerf's shape. Sorry I have no pics, but I want this to not take three days. Take out the pieces that support the barrel. Draw a map if you have to, because this can get very annoying to put back. take out the barrel with the supporting orange piece and throw away the orange front piece. This may reduce slight accuracy, but you can now use sonic micro darts, and you need to to do my 3rd to next mod. Unscrew the back of the barrel. take out the piece. Unscrew the 3 screws on the back, too. Make sure to keep mapping. Unsrew the last front screws. Get small pliers or a large screwdriver and pry it open, going all around. Take out the springs and the 3-pronged pieces. Put the barrel back together. Take out the air pump and stretch the spring. Put back the gun, using your mapping. Now, for the fun part. Drill a hole through the center of the barrel, big enough for your flashlight. You are done. Have fun.

Hello, I was wondering if anyone can make a instuctable for me so I can wire some rca plugs for my science project i'm working on.

So I got my Nerf Longshot a few years ago and I decided to mod it. I went and removed the air restrictors. Being Really Excited, I went to go test it out. It turns out that it made the gun shoot half as far with almost no force. What's going on???

My son is 6 year old and he still loves his cozy coupe...but he is too tall for it and has to ride side saddle with his legs hanging out the door.  LOL  I would love to figure out a way to raise it up so that he could still ride in it normally.  Has anyone done this?  Why don't they make a bigger version for older kids?   I want to keep my son playing outside as much as possible before the videogame bug bites him.

I bought a sensational headset with mic for my 360 and it doesnt work well. I bought it cheap on ebay for around 11 cents. I have another phone headset that works, but the earpiece rarely produces sound. I want to combine the headsets so i can hear through them and talk too. Any suggestions?

If anyone has a good modification that will 100% definitely work for the new nerf recon, please tell me.

 I wanna rick roll my school, and our intercoms work with phones...i need to build a jack where i can plug my ipod in one end, and plug the other into the phone....is this possible? 

For my Nerf Gun Mod I need a 14kg load spring. After a VERY long time of looking I've come up empty handed. Where on earth am I going to get a spring for my longshot?

Hi everybody. Im looking at the very popular Personal Soundtrack Shirt   but I was wondering if theres any way to change /modify the speakers to make em work with a pair of these http://www.youtube.com/watch?v=9s_oEVOoLeE Thanks in advance /danny

Want a sawback knife, not willing to spend 70$ on one just yet. So with a file, a hacksaw, and some sharpening stones, could one easily make a "saw" or some very coarse serrations on the back of a knife suitable for bush craft and basic survival/trap/shelter construction? wouldn't need to cut down a tree, just make notches in branches for traps, and basic things like that.

The original problem was that the laptop wasn't getting power. The shop I took it to said it was the motherboard and that it wasn't worth the price of a replacement. So, I'm not 100% positive that this is the actual problem, since i declined repair, but that's what they said. Everything else is in good working condition as far as I know (including the power supply and battery--we tested those). I'm now running snow leopard on a macbook--I was hoping that the screen might be turned into an external monitor without using the motherboard, but i've seen all the answers about needing a controller and all, so I don't expect that. Still, getting any use from this thing would be great. Any ideas?

I am trying to build a portable slimline speaker set for my Ipod. I have to sets of computer speakers that I can use. One consists of 2 separate speakers with 3.5mm jacks. I worry that they may draw more power than the Ipod can supply. The other set has a USB and a 3.5mm jack for input. Is it possible to build (or buy) a battery pack (or somthing similar) to power the usb? Please give any and all suggestions on how to build and how to get best results. (I am open to buying parts or new speakers that would work better) I am doing this for kicks (but i do want to get a good setup out of it) so please don't say: "just go to such and such website and buy such and such portable slimline speakers" Thanks

On July 13, 2014, the unofficial yet famous K'nex war will take place in Freemont Ohio and luckily this year I coming back a veteran. With all the experience and advice I got from last years war I will be a stronger competitor this year, with more powerful and sturdy knex guns. With all the fun and preparation involved in getting ready for a knex war it made me think of all the iblers who don't get to come down to Ohio for the war, so I decided to try one of my ibler's war guns at the knex war.      I ended up building the Red Book of Westmarch's R5 Defiance, A bolt action K'nex gun specificly designed for K'nex wars, and while he admitted he hadn't tried it at an official war he had tested it rigorously so he knew it war reliable. My stock version worked really well, it hit the range that Red had showed and it was pretty reliable. As you can easily tell by my final product, I changed practically everything about the gun. Why? Why would I do that if I was happy with it? Well there's a small difference in being happy with something and being confident with something. While the R5 was very reliable, I had trigger issues and a little chambering issue.          That also being said I also have an engineering saying that goes building something is easy mindless work, making something your own, that takes skills. So I made my R5 my own and changed everything but the magazine and general body. I added: a new trigger mechanism that increased pin draw ( the stock pin draw was fine too), magazine lock ( I have a vendetta against friction in K'nex guns.. ),  Upper chambering mechanism (because it makes the chambering smoother in my opinion), and a barrel (which prevents yellow rods from tumbling end over end).    My modifications only increased the reliability and the overall functionality of the gun. I would definitely recommend building the R5 Defiance because it's a great gun and it'll definitely help you in a knex war. Like any gun though, try it out and make it your own before using it in battle! Anyway thanks for reading and if you have any questions I'll be around.     JonnyBGood            (also if your wandering why I didn't break this up into paragraphs, instructibles doesn't let me use the return key for some reason. Sorry for the huge paragraph of rambling!)
