Sanding Laser Etchings and Saltwater Etching Through Anodization ?s

I own an iPod Shuffle, 2nd generation, silver. It is very plain, and I've recently been reading up on saltwater etching. I want to remove the standard Apple logo from the back and etch my own text (it will either be "iMake" or "iBles", I can't decide). I've come upon two roadblocks, so far, those being: can I sand laser etchings (the Apple Logo) off, and can I etch through the player's anodization, or would I need to sand that off? I don't really care if it doesn't turn out perfect, or looks like a total mess. It's not like I paid for the thing. Thanks for any help!

How to make (or where to buy) the "color hand bands" for Nerf Cosmic keep-away?

You throw around the ball, and it detects the band your wearing. so if the person wearing the red band, catches the ball, it will say "Red Caught the ball! New round?" or something like that. so, how do you make those bands? Or, Where can i get them? PS i know it dosn't sense color. i tried that already, there's somethings inside of the bands

How to preserve plaster of paris and avoid it breaking away? Answered

I'm making the Good Samaritan gun from Hellboy per the instructions on Indy Mogul. One of the parts of the gun, the barrel, (erm....where the bullets go), is made from plaster of paris. From experience, I've learned that this can break on its own eventually. Is there any way to avoid it weakening or breaking? Perhaps covering it with something?

Reasons why we should do away with internet filters.

Internet filters suck.  Here's why we should throw this sh*t away: - Most filters restrict LEGIT sites, like wikipedia, Youtube, Facebook, etc. - It slows your internet speed down somewhat. - The workarounds make your surfing experience way too slow. - Censorship in general sucks. - It takes away freedom, which is already gradually ebbing away.. - So people don't try and steal my iPhone to look up porn because the PC's are blocked. People should have common sense to just hit the X button if they stumble on content they find offensive.

Went away for the weekend- these were waiting when I came back

A mere three months after ordering, I went away for the weekend, and my Raspberry Pis (raspberries pi?) were both waiting for me when I got back today.  One of them is already earmarked to become a media centre/web server/NAS all-purpose box.  I've got a couple of ideas for the other one, but I could always use more inspiration. What should I do with my second slice of Pi?  Patch* for the best idea (even if I don't actually make it).  No, I won't accept "send it to you" as a suggestion :) I'm already torn between a MAME arcade cab and some kind of carputer. * Judge's decision is final, one per customer, no cash equivalent, consult your physician if symptoms persist

heat isolation, how to keep heat away from electrical cords? Answered

 hi, we're building our own heating system. we're using ventilation tubes(often used on dryers) to distribute hot air through the shed, but it needs to get pretty close to an electrical cord(+/-1 inch) and the tube gets pretty hot(at least 200 degrees Fahrenheit). which is a bit of a problem, the electrical cor is the type you'd burry in the ground, and it looks like it shouldn't melt too fast, but we still ant to isolate it, any hints/tips on what kind of material to use would be appreciated...

Take a Photo, Get a patch! (my new monthly give away)

Some of you may have noticed that I stopped doing my famous 'Desktops of [current month]' Forum topics.  These few days of past, I may have bought myself three cameras, so it prompted me to think. Thus I bring you my new monthly forum topic, which I hope more people can get involved with than the Desktop wallpaper topics. Essentially, every month I am going to post a topic with a distinct theme. The task then is for you guys to go out and take a picture along that theme, and post it as a comment. This months theme is an introductory one -    Camera Self Portrait Go and take a picture of your camera using your camera. Make the most of reflective surfaces, and interesting techniques. If you own more than one camera I want you to use your favourite, because this is the first topic, think of it as a 'hello, meet my camera'. You do not have to be in the photo, so you can still take part if your conscious of putting your picture on the webz. Remember, the best camera is the one you have with you. I know that one of you could easily take an amazing picture with your phone, while someone with a nice Canon 7D could struggle to find a nice shot.  Every person who posts gets a patch!  Here is a picture of me with my Canon just after I had got my 50mm prime lens!

How to detect yellow school bus from 100 to 200 yards away? Answered

Is there any type of electronic component that I can use to build something to detect a yellow school bus that is up to 200 yards away? I live on a very straight busy road. From my mailbox I can see about 300 yards down the street before it curves. Is there something out there that would allow me to build a device, mounted to my mailbox post, that will chime a bell in my house when it detects a yellow school bus approaching from at least 100 yards away? Note that I believe it must have the ability to detect color because we also get a lot of big trucks driving by that could set it off if I were detecting by size. Just wondering if this would be possible. Thanks! - John

Extending a mobile phone's camera away from the phone by adding some longer cable?

I have a little project where I am looking to extend the mobile phone's camera a few meters away from the phone while still being able to use the phone as a viewer. I would like to use the camera and the phone because the power source is already set up, the camera and the phone mesh without trying to add a camera to a small LCD screen, and I have loads of old mobile phones and was hoping to be able to recycle one or two of them. I would like be able to place the camera of the phone a meter or two away and be able to view the video on the phone. This could be useful in looking in hard to reach places within reason. I could also maybe set up a little rig for attaching the camera to my motorbike helmet and recording without strapping the entire phone to my helmet. This could also maybe be used for making a little rear view camera for my bike by placing the phone on my handlebars and routing the camera behind me. I know they sell back up cameras, but again I am just looking to find a use for my mountain of phones. I assume I would just need to find the camera's cables and extend them, but I am also going to assume they use a ribbon cable. I was just wondering if anyone knew of a way to extend the camera away with a bit of wire soldering or something along that nature. Would the mobile phones with VGA cameras use a system other than ribbon cable? Hopefully someone can wrap their head around what I am describing and help out so I can find something useful do something with a few of these outdated mobile phones!

Portable power source for low power usb device when away from computer?

Hope someone can help.  I've looked at all of the usb charger instructables, but most of them are for Ipods and such.  This device, I think needs to be low power like required by keyboard or mouse?  The manufacturer says this about powering the device: "works only on voltages of 2000mA or higher, such as a PC. It will not work while connected to a USB or home charger, or with a Mac" I would like to use this when away from my computer and think one of the Altoid power chargers would work.  Would like to make a solar one for the car, but regular for inside the house.

how to wire an earphone jack from my bose radio to a speaker 50' away.?

My bose radio does not have an outlet for any speakers I might have. Bose said the only way I could activate a speaker 50' away in the basement is to use a headphone jack wire that is plugged into the Bose. It should transmit juice to the speaker to transfer the sound. I have a breathaudio speaker  with two sets of red and black spring loaded terminal posts. When the jack goes into the Bose radio it naturally cuts the sound from the Bose radio itself and that's fine. I just want the juice from the jack to go to the speaker in the basement to enjoy. Is this possible? I'm working with very fine headphone wires from the jack wire itself to transfer power to the speaker via speaker wires that will attach to one set or both sets of the black and red spring loaded terminals on the speaker. Thanks, Jon Burnham  jonb2@hotmail.com

Anyone know of a quality wireless switch for a light approx 70 feet away on a shed in backyard?

I would like to have an outdoor light on my backyard shed/ shop, which I would like to be able to turn on and off from inside my home, which is about 70 feet away. I know that wireless switches are made, but I can't seem to find a good quality, reliable, reputable brand. The only ones I have been able to find on the internet are not getting the best reviews, such as Heath Zenith sold at Home Depot, etc.. Does anyone know of a brand they could recommend? Price isn't really an issue, to keep from having to run wire out there if I can avoid it. Thank you. P.S.- I did think briefly about just using a motion detector, but that would only come on if there is motion, and that doesn't fit my needs. What I need is to be able to turn it on if, for example, I hear something out there and I need to look out of my back window and turn it on to be able to see what might be going on out there, if anyone is trying to break in, etc..

Need help with audio trigger for camera....how do I generate a beep/click 300m away?

Hey guys, I have a DSLR Canon 550D camera with Magic Lantern modified firmware installed on it. This firmware allows the camera to be triggered by sound, utilizing the cameras onboard mic. The level of sound required to trigger the camera can be adjusted. What I would like to do is have the ability to trigger the camera from quite a distance with some sort of audio trigger. If I have this trigger close enough to the mic and adjust the levels it would only need to make a decent click. To get decent range I am assuming I will need to use a radio device? Can anyone think of anything cheap and compact that could work as a trigger? Using walkie talkies is the obvious thing that comes to mind but these are rather bulky....ideally the trigger would be small enough to clip/tape to the camera. In terms of range, 200-300m would likely be the upper limit. Any thoughts would be appreciated :)
