E-Ink (or LCD?) keychain fob

(or: one fob to rule them all)problem: too damned many keychain fobs for all the supermarket and other retail discount clubseach one is designed to be nothing more than advertisement on one side (store logo) and a bar code on the other.solution: electronic keychain that can be programmed to display a store’s logo and discount club’s UPC code. a small LCD might work, but would be difficult to properly scan with bar code scanner. plus, LCDs drain batteries whenever they’re on.something like electronic ink would work better. it’s more reflective, only uses batteries when changing the pixels, and the display only needs to be black and white, so why bother with LCD?(http://www.eink.com/)the whole thing could be really tiny, needing only the controls to scroll through the programmed UPCs, the display itself (maybe .5′’ x 1.25′’), a small battery and a mini-USB port (for plugging into a computer to program in the UPC codes).anybody want to build me one? my keychain’s getting a little cramped.

Love Sucks Party

My friend Bug is responsible for a fine Valentine's Day tradition: the Love Sucks party.This party is held whenever he's single (according to the rules below), and is open to any single friends and their single friends. It's usually held at a distinctly non-romantic type of restaurant with ample seating and strong drinks. I know of at least one marriage that's come of Love Sucks parties, but that's really not the point, is it?The rules:1) Single is defined as a) really single, b) your SO is at least 3,000 miles away, or c) you don't have a date for Valentine's Day and your romantic entanglements require a white board for proper mapping, otherwise known as the Circus Trainer Clause. (As in, "my girlfriend is out for dinner with her husband and her girlfriend, the circus trainer..." or something equally convoluted enough to require a whiteboard for mapping.) Either way, participants are likely to be a bit grouchy about the holiday.2) Single friends can bring another of their single friend as a "non-date", ie someone they would never date. There may be more rules, but as I've never been (un)lucky enough to attend one of Bug's Love Sucks parties I'm a bit fuzzy on the other details. (Bug, can you help out here?) It should be noted that he's NOT planning one this year, as he doesn't qualify to attend. ;-) This shouldn't stop you from picking up this worthy tradition. Just make sure to bring a whiteboard.UPDATE: here's Bug's official description and invite template for all to use.

How can i keep my attic warm on a small budget?

I live in my attic year round. its managable, however when the overhead stars are open, it sucks the heat from the rest of the house. I live in a VERY old house (still bark on the beams) with a metal roof but no insulation in the attic. i would love to not have to put in insulation and finish the ceiling (sheet rock etc.) because it would be costly and make it unhospitable in the summer. I was hopeing that someone out there had a very cool method for keeping some heat in, or creating cheap heat easily. the rouble is that all the heat simply goes out the roof, so space heaters wont work. thank you very muxh for your help! ~farley

Alesis Nanoverb: Effects Unit or new Project Box? You decide

Hi Everyone,Well I posted this as an Instructable, but someone pointed me to the forum, so here I am. My Alesis Nanoverb hasn't worked in a while. Initially it just made wall warts stop working. But at some point, it stopped powering on. Since I have minimum skills with electronics and have only recently started to solder together my own altoids tin light w/LEDs, I thought I should ask for help from the sages in the forum.I posted the instructable at: https://www.instructables.com/id/ERP4FYR1NAEWUSLQ0W/Any advice you could give would be helpful. For example, where do I test it with the voltsmeter to see if it's got continuity? Which selection on the voltsmeter do I use for continuity? Etc.I've provided pictures of the guts and a picture of me testing the Nanoverb.THANKS

A Pile of Junk

Can you believe my wife called it that? Here I find out that a friend of a friend's company is clearing out it's inventory, so I score for next to nothing, all this cool vintage tech. And the first thing my wife does is call it junk, and second tell me "Don't bring that into MY house". So I desperately need to boast somewhere. Here's what I got. A PII notebook (won't boot, past setup screen needs new cmos battery) A PIII notebook ( boots couple bad spots on screen (Thinking sacrificial computer for dangerous projects)) PIV notebook Cracked screen (Thinking of docking it to replace my crufty old celery desktop) PIII Desktop (needs harddrive (same destiny as the P3 notebook) LCD projection panel, just 640X480 but NIB. A video camera, old school tape, but top of the line for it's vintage. a laser printer and a eighties vintage teleconferencer. Went around giggling like Beavis all day. Acquire any cool junk recently?

Where did you get your start?

Hey all, I've been looking through this site a lot, and I have been intrigued by all of the amazing projects. However, I feel my knowledge of electronics is very lacking. So my question is, how did you begin getting involved in electronics? Is there a web site I can go to, or a book I can read, that will explain to me all of the basics? For example, something that will explain fairly in-depth how circuit boards, transistors, resistors, and all of those great things work. I appreciate any help I can get.

Ipod flash drive

Hey I was looking for a broken ipod mini the other day so I could get a new case for mine, and I noticed that many of them still have working hard drives. That's when it hit me. I was thinking, why let all that space go to waste, when you pay $80 at the store for just a 2 gig flash drive. Would it be possible to make a flash drive from the hard drive in the ipod? At first I was just going to wire the drive to a USB port, but I'm thinking that may not work. Does anybody out there know more about how flash drives work? I think I have a good idea, now I'm counting on your imput!

Want your own factory for $2400?

Article in this weeks's New Scientist - they've developed a desk-top fabricator:The standard version of their Freeform fabricator – or "fabber" – is about the size of a microwave oven and can be assembled for around $2400 (£1200). It can generate 3D objects from plastic and various other materials. Full documentation on how to build and operate the machine, along with all the software required, are available on the Fab@Home website, and all designs, documents and software have been released for free.Unlike commercial equipment, the Fab@Home machine is also designed to be used with more than one material. So far it has been tested with silicone, plaster, play-doh and even chocolate and icing. Different materials can also be used to make a single object – the control software prompts the user when to load new material into the machine.Article: http://www.newscientisttech.com/article/dn10922?DCMP=NLC-nletter&nsref=Video of it in action: http://web.mae.cornell.edu/ccsl/temp/EvanMalone/FabAtHome/SqueezeBulbDemoMovie.wmvWhat would you build??

Kiting injuries today at work

Don't expect any website updates in the next 12 hours, Rachel and I both drew blood while kite-buggying in the parking lot this afternoon. OK, the injuries are pretty minor in the scheme of things, I just wanted to brag that we went kiting during work, at work. Previously, I've always had to leave work to kite. We didn't take any pictures while actually out there, so I've included another image from my archive to show what it should look like. A sandy beach probably would have been a lot smarter than concrete. Oh well, I should probably order Instructables-team helmets.

50 LED Light String

Im trying to wire a string of 50 LED's that are 200mA each. They are all connected in one long string, end to end (in series, I think). I'm having trouble trying to figure out what kind of power source and resistors to use and how to wire the resistors in. In the past I've wired 1 or 2 LED's to a 12 volt power source using a couple of resistors in parallel, but this project is much bigger and I'm worried about current loss and the very high voltage needed to power a string of 50 2 or 4 volt LED's in series... is that like, 100000 volts, or what?? Any guidance would be appreciated.

NEED HELP! LED project .....

Hello, I'll make this as quick and simple as possible ... I'm working on making a headlight for my motorcycle (Kawasaki KLR 650) ... I have about 55 watts to work with (probably a little more than that now) ... it has to run on a 12v system... How much light is it possible to produce with this amount of power? ( I might have as much as 60 - 90 watts to work with, as I've swichted all the other lights on the bike to LEDs so my power usage is down from stock) It would have to have a running light ... and a "bright" light. I have no experience with LEDs, and A minimal amount with electronics. Any help would be apreciated.... I have no idea where to start with this... Requirements: Waterproof Super Bright (brighter than a 55w halogen bulb, would like to be as bright at possible) dim and bright mode Able to run in 0 - 130 degrees ferenheight evironment(spelling)

Also, if somebody could tell me where I could find some (doesn't have to be brass - as long as it is metal) ... I need about 20 minimum to begin with. Thank you very much, Iza Bl..

Is there a particular season for ginger root?

I was grocery shopping... one place (a Walmart Neighborhood Market) did not have any ginger (they did about two months ago). The next place (Publix -- a large supermarket chain in the south east) had some, but most of it was moldy and disgusting (surprising because Publix tends to keep very high standards). Just curious if there's a reason why I can't find any. I'm looking to experiment with homemade ginger ale - I had some in a restaurant, so I want to do some testing to come up with a similar recipe :D

Instructazine? Good/Bad idea? (Open sourced by the way :) )

What is Instructazine you all say? Well it’s pretty much this…A magazine by the makers for the makersThere should be a little section in this website that contains 3 subsections...> A instructazine development wiki> 'The current issue of Instructazine> And an archive of past InstructazinesThe Making Of Instructazine:Radical eh?Well the open sourced bit of this idea is that anybody within this community (that’s you and me!) can contribute towards the next issue of the Instructazine. This is much like wikipedia, but working towards the next magazine.Once everyone has contributed within the deadlines, others would start compile these pages together and released it in multiple formats. (Html, Pdf, Jpg, A physical hard copy magazine)The Link System:The link to the current issue is provided by Instructables free of charge. However if you want to support Instructables, it would be very nice if you could order a physical copy of the Instructazine, in which you are paying for the print and an optional donation to Instructables depending on how much you think you should donate. (Although I personally wouldn’t mind if there is a minimum of a dollar donation)Sound pretty cool isn’t it?Too bad it doesn’t exist yet!>Now lets see if anybody here think it’s a good idea?>Also if such initiative would go ahead by the owner of this site, will you gladly do you bit to help out?-Signed Akimbomidget

I'd like to have as final product, a led light connected to a PC via USB - that has a software-controlled dim functionality (ie, 1 is on, 0 is off, values valid 1 < x < 0). I'm a seasoned programmer, but the hardware side of things has always been a mystery. Where to begin? Is this a complex project? Cheers. Alex
