Geek-Protection Stickers? Call for design suggestions!

So, Star's in jail in Boston for forgetting she was wearing some electronics.I sent this to Xeni Jardin, and she added it to the BoingBoing story:Star was an intern at Squid Labs this summer, and is an all-around awesome geek who loves to build things. FYI, friends at MIT say she wears the hoodie on a regular basis- it's just unfortunate that she had it on while trying to pick a friend up at the airport. MIT students don't really do mornings, or worry about what they're wearing, so I can't imagine she'd even think about her clothes before heading out to pick up a friend at the airport before 8am.When Star gets out we'll have her do an Instructable on 1) how to get arrested at the airport without being shot, and 2) how to package your homemade electronics to look purchased.Maybe BB and Instructables should start handing out some official-looking stickers and plastic covers to make breadboards look more commercial- it will keep our readers away from automatic weapons. I just got email back from Xeni saying, "Let's do those stickers!"Question: what should the stickers look like? What should they say? Make some suggestions, or submit some designs here, and we'll print them up!

Covering a stickered laptop with epoxy resin? Answered

Hi! I recently got a new laptop and I covered the top cover with stickers and it looks pretty good if I do say so myself. I didn't want the stickers to peel up or anything so I went on over to the hardware store and bought some Krylon Crystal Clear spray, which is an acrylic lacquer based spray. I sprayed a whole 32 coats on that sucker and it was still paper thin. It's as if I simply made the surface shiny, and the stickers could still easily peel up. So I did a lot of research and I found a lot of things but I figured a 2 part pour on epoxy resin was the best choice. It's thick, self leveling, self doming, and it cures instead of air drying. My goals from the beginning were to eliminate surface texture altogether. I want the end product to be like those table top bars with stuff encased inside within a clear glass-like coating. I have found a lot of stuff, but I have yet to find anyone that has done what I am trying to do, and since it's my new laptop, I have concerns. How durable will the epoxy be? I want to make sure that it will be able to withstand the life of a college student, although I'm a quite careful one at that. Will the epoxy have any trouble bonding and staying bonded to the Krylon spray? It's an acrylic lacquer based coating according to the company. I don't want the shell of epoxy separating from the top of the laptop. I'm worried about bumping the edges and having the epoxy chip off or just separate altogether. That last question is the main and most important one, really. The last thing I want happening is for the epoxy to dry and then separate from the laptop or crack or chip or something. The epoxy I've settled on for now is Envirotex Lite, I'm not sure how much epoxy differs between manufacturers. I've emailed several companies asking lots of questions and I've gotten a lot answered, but these ones have yet to be solved. Thank you so much for reading this and any input or advice would be greatly appreciated!

In fact, while looking under the submarine, there was a sticker written "49Mhz - 3". I guess it is referring to Channel 3 - 49.860Mhz.  So could I buy a 49.860 crystal, remove the 40Mhz crystal from remote controller, and get my submarine to run again?

Help with iPod Classic USB Portable Charger? Answered

I've seen so many portable iPod chargers out there but I'm not that experienced to handle the electronics. So, what I wanted to do was to take apart old adapters and connect it with a 9V battery (with the battery slot from an old alarm clock) A couple of questions I have are.. -Does the adapter have a regulator to bring the 9V battery down to the proper amount of volts needed to charge the iPod? -How much power is needed to charge the iPod? -On the battery wire thing, which wire is negative, which is positive? -Which wire (on the battery slot) is supposed to connect to which wire on the circuit? -On the circuit board, which is negative, which is positive? Specs: -(Relying on the informational sticker on the adapter) Circuit board input: AC100 - 240V 50/60Hz -(Relying on the informational sticker on the adapter) Circuit board output: DC5V = 200mA -More specs in pictures Hopefully, the circuit board already has a regulator, to bring the 9V down to a 5V, so I wanted to post this to ask the experts on 'ibles to see if it probably has a regulator or by using the pictures.. thanks so much! If you need more pictures of anything, just ask; thanks again for helping :D

I need help identifying a half built server I found in an old storage unit?

We were recently cleaning through a storage unit. I came across what appears to be an old half-built (desktop) server. It is not completely built so I am looking to finish building it. It is custom built, so there are no stickers or modal numbers that I can see. It has 4x 1gb ram chips. Two hard drives (with room for three more), fans, processor, and dvd drive. I knew how to insert the ram chips but I don't know how to connect all the power cables inside. I'm hoping to find instructions some place. I could use some help. I have done some computer programming, so I know what the parts look like and function to some degree but not enough to put this together. I don't want to risk damaging it since it may be worth a lot more than a 10+year old pc. I don't think there is an operating system loaded, and I'm not sure how to go about that either. Any suggestions?  Although I can't find any stickers, there may be some other label located somewhere, but it wouldn't be too obvious. Any suggestions on where it might be located?

I was going to try the DVD burner laser and just cut through some paper for now but im wondering what the capabilities of the higher wattage lasers are. I know there are several 1-2+ watt lasers on ebay, what could they mange to cut through? Could I cleanly cut cardboard? What about vinyl for making stuff like decals and stickers? Im wondering if spending the extra money on a better laser would be beneficial or not so if anyone has some good comparisons or ideas let me know. Im on a tight budget for this build so a co2 laser is WAY out of the question. This is my first CNC build so its mainly to learn but the more capabilities of the CNC the better.

We also are looking hopefully below 100 @most 150 dollars.

Whasing machine motor help?

Hi, I have a washing machine motor that I want to use for some projects of mine, and before I burn it using the wrong voltage, I wanted to ask you guys how it's done right. The motor is from a Whirlpool washer, and it's got 5 wires going in it.  From whirlpool's manuals I understand that leads 1,2,3 are the motor windings, and leads 4,5 are the tachometer. The resistance between leads 1 and 2, 1 and 3, and 2 and 3, are all 6 ohms. The attached picture shows the sticker on the motor. My question is, how do I make the motor spin?  Do I just plug it to the mains?  I'm guessing the tachometer wires are useless to me, since I don't have a control unit, which means I have 3 wires to work with.  Also, is there a way to make it spin slower/faster without a control unit? Thanks for the help!

Wiring a salvaged CD drive eject tray mechanism and motor into a car?

Hi everyone. I'm making a custom back-up camera monitor mount for my brother's car. He doesn't live in a great neighborhood, so we want it to be hidden when not in use. We were just going to conceal it in an unused cubbyhole drawer under the radio, and he could pull it out and push it back in as needed. But as I was sitting at my PC, I bumped the DVD eject button and it occurred to me that we could spend a little more effort and have it be powered using a salvaged CD drive. I'm not an electronics guy, but I've pulled apart an old CD drive and the motor and gearing system seem fairly straight forward. The car is 12v DC, obviously, and the eject tray motor is also DC, but the spec. sticker on the motor is unreadable, so I don't know the voltage.  There's an obvious limiter switch in the mount that flips when the tray is fully extended, and what looks to be another one on the circuit board that flips when it's closed. Can anyone help me with wiring on this? I'd like to have it so he either presses a concealed switch to open and close the drawer, or possibly have it tie into the switch that activates the back-up lights. Thanks!

Use the laptop's backlight for the illumination, and broadcast your message or design with fluorescent markers.Magnetic surface -- magnetic laptop poetry.Corkboard -- Remember to always use the flush thumb-tacks!Chalkboard -- perhaps a little dusty, but you could probably end meetings early by "accidentally" running your fingernails across it.The cool thing about all of these materials (perhaps excluding the corkboard) is that they could easily fit into the minimalist, clean-lined laptops that have become the norm. But, they allow you to really be expressive when you need a splash of something unique to break you out of a funk -- or just a note to pick up milk.

How to make Flip Clock Numbers and build a "like"-counter around it?

Hey All So I've got this client, who's absolutely crazy about the "FLIKE" (A physical like counter.). But he can't have it for another couple of months, and he'd like it to be a little more custom... Long story short, I might end up making a similar product in a few weeks. it will probably consist out of 5 digits and if it's up to me (not sure what the client wants) I'd stuff them behind a long picture frame. Something like this but actually mechanical and not just a picture of it:  http://www.notonthehighstreet.com/thedriftingbear/product/personalised-framed-vintage-flip-clock-print So I started googling every hardware piece I needed and it turns out it's a huge pain to find Flip Clock Numbers / Flip Board Numbers... whatever you want to call them. (What's the right name btw?) You can't just buy these things, let alone in a custom size. So the idea is to build them myself. I found this on wikipedia, which gives a clue about the inside: http://en.wikipedia.org/wiki/File:Analog_clock_with_digital_display.png So I'm figuring out what needs to go in it to make this work. (I'll end up making an instructable about it) The numbers themselves are going to be made out of vinyl stickers. You can easily buy those from ebay in about any size if you look for them. The stickers will be put on to plastic boards. But I'm not totally sure what kind I should get. They should be thin and must be able to stand up straight, yet "easy" to fold. I'll probably get them lasercut, but you should be able to cut them by hand as well. Currently I'm thinking about gluing small metal or carbon rods on the back of those letters. Although I'm not sure if that would be strong enough. Would it be enough to file one side of the rods to get a bigger contact surface? (What do you guys think?) I'm planning of putting the half letters in a drum of ABS or PLA. it should be shaped like this:  |--------| I'm thinking about 3D printing this. But no idea how it'll do... One side of the drum will be connected to a small stepper motor (5.625° with 1/64 reduction). I don't have real experience with stepper motors, but this resolution seems more than sufficient. The other side will be connected to a metal or plastic positioner. Each digit might end up with it's own "unit" so I can swap them separately if they'd break. I've got great experience with lasercut plexi, so I might use that because it's more accurate than wood and I might have some lying around. I was first thinking about 1 stepper motor and a set of gears. I decided not to do that in the end because I don't have good experience with making gears and I can never find the right sizes online. Also, it'll make everything way more complex. So each motor will have it's own controller connected to it. Those controllers would have to talk to an ATMega or something. (I'm planning on using an arduino to prototype, but then just swap the chip and make a stand-alone version without usb etc) The ATMega has to be connected to the internet of course to get the current number of likes, so I'd connect it to a raspberry pi via I²C. I'm not familiar with the GPIO pins on the pi so I figured this would be a save and convenient way to handle this. The ATMega is robust, and I love the Arduino bootloader. A sketch is written in no time, but I have no idea how to start writhing this code for the GPIO pins. So why the Raspberry Pi? First off, this thing might end up being wireless, and since a wifi module for the arduino costs as much as a Pi, I figured this would be easier. The plan is to make the pi run python script that could ask the number of likes from the facebook API. Once returned, it'll send +1 or +5 or +10 over I²C. The arduino shifts the numbers to the correct position and replies with the total number it's displaying (3012 for instance). The PI can then recheck if everything is in sync. As for the set up. Since we have Pi, we can put on a LAMP stack (I know, this is overkill, but it wouldn't hurt either). So for initial set-up, we'd connect the counter to ethernet, browse to it on a different computer via "http://counter.local". And we'd be presented with a web interface. You'll be able to set the URL of the page u want to get the likes from, set and reset the number that is displayed on the counter, and the WIFI settings. The WIFI settings can be saved in the wpa_supplicant.conf file and on reboot it'll automatically connect to this network. From now on the whole system is manageable over wifi via a html interface. For debugging I might enable ssh though. So I guess you've got the whole outline now. I'd like to get your feedback on this! And this for the mechanics, electronics, and software side of things!

Help coming up with how to make robotics project (RFID/iButtons/sensors/chess/microcontrollers)? Answered

Hi all! :3 For my 2-year high-school robotics project (last two years of High School) we were allowed the freedom to choose whatever project we felt like working on, as long as it got approved by the teacher. Me, being a huge fan of chess, decided to make a chess-related project. Unfortunately, I dashed into it without giving it much thought. So I'm here asking you guys if you can think up of a way for me to achieve this. Afterwards I'd like to take it a step further and have it not be related to chess at all, and make my own board game with my own rules, but that's afterwards. Alright, I'm really bad at explaining things (English = not my native language), but here goes. I'd like to make an interactive chess board. The chess board would be grid-based, obviously, with possibly LEDs inside each square. I'd also have my 16 (or well, 32) chess pieces that would all be custom made. (I have access to any materials I need, so don't worry; I have a big budget, 3d printers, plenty of microcomputers and microcontrollers, you know. All I need to know is what to get X'D) Now let's say I place/take off a piece on the board. I'd want the grid to light up the corresponding squares/blocks. E.G: I pick up a pawn, and the square right in front of it lights up. So You understand what I mean? If possible there could be some button on the chess piece. Heck, it doesn't have to be a chess piece, as the shape would make it weird. I can just have blocks with a button on top and a little sticker indicating what piece it is. Anything like that works. I'm guessing the board would have some kind of microcontroller/microcomputer integrated into it that would process the logic for the lights/movements. The part that really gets me most is how it will know what chess piece it is and how I would go about implementing the code and such. If you had to make this, and had 2 years time, how would you make it? What kind of materials would you use? I've been doing a bit of research on this, and through my research it seems like using Arduino or something of the like along with iButtons or some sort of RFID/NFC would be ideal. I don't want to do anything optical, like utilizing cameras, etc. I'd like each piece to store memory and information related to it and for it to be able to be read and written by the board (well, the microcontroller/microcomputer). Again, I don't have that much expertise with anything related to radio frequencies, or a lot of the part of the hardware-side of the project, I'm more of a software-buff. But I really want to learn which is why I'm doing this! I have a bit over a year's experience in C++ and Java, since that's most likely going to be required. Anything helps! Thank you so much for your help! :')
