I am starting a new project, I want to tweak some of my old design, design some new systems, and reverse engineer some other stuff to create a whole new system that is effective and powerful. I am planning on making this a full turret, so don't worry about size at all, only effectiveness. Let me know if you guys have any ideas of systems to contribute for the plan (see my previous post for details on 'systems').

I am very displeased with the site design, I don't know when it was implemented, but I am familiar with and happy with the old site design from summer of 2012. I do not like the layout with the steps, the sliding bar at the top of the page that is parented to the top of the browser is annoying me and with whatever new layout you have used to render pages, my browser now lags terribly with simply just scrolling on the page. The part that really pushed me over the edge though and made me post is the picture layout inside the instructables now, the old system worked with the pictures being clickable thumbnails side by side, this new crap of what appears to be a frame in the instructables with the pictures isn't working for me and I am not able to read instructables because the images do not stay in the frame and over lap over paragraphs and cover so much information. If this new design works for people great, but for people like me, I ask that I be given the option to use the old design.

This is a gun i have been working on. The cool thing about it is that to fire it all u have to do is pull the trigger and it will pull the firing pin and shoot it. This makes it a billion times faster to shoot. idk if i should post or not so tell me what u think

From the MAKE blog, I found an outstanding article in The Economist on product development in the age of rapid prototyping. In their usual fashion, The Economist gets into the nuts and bolts of how a pair of entrepreneurs used rapid prototyping and Kickstarter to create a real product from their initial ideas. It's a great case study for DIY-ers who think they have something marketable, to show how they could make that happen.

I've been working on a new ball machine for a few years and finally decided to tear it down and start anew; one thing I did save was this wheel. It uses chain for a rim to make a "perfectly" circular wheel. With grey rods on every rim connector it is quite heavy, in my ball machine I used a delay to send 3 balls onto it at once to make it spin nicely. If you want you could only use once white connector and 8 grey rods to make a lighter frame that would spin well with only one ball on it. Peace! ~IaC

Hello everybody! I've moved most of my robotics projects to Let's Make Robots (All LMR are belong to us!) and I'm gonna do some wood-working now! I decided to build a kayak. Why? I dunno, I want to build one, and I always wanted to go kayaking. No I'm not gonna go take lessons (tips/tricks are welcome), I'll train myself. I'm expecting a couple capsizes. LOL. Anyways, I found a program that helps to design kayaks called Kayak Foundry. The software tells me where to put the sheer strip, where the waterline will be, and it also generates the forms to build from. The only problem I have is that this thing will cost $400-$450 to build. Before I invest that kind of money in a possible failure, I need to know if I have a stable design. Below are the cross sections and a model I made in Google Sketchup (gotta love free software!). Take a look at them, I need to know: -Is the design stable -Will it float with a 185lb man in it The software gave me a stability rating of 90 (out of 100, with 40-50 being a racing kayak) Also, there are pictures of data from the software. the red line on the graph is my design, the black line is the target. Also, on the volume distribution curve, the line should be right in the middle (the cockpit or whatever it is called should be in the middle of the boat.) I guess I forgot to save or something. If you can help, please do. I'd rather not spend $400-$450 dollars on an unstable boat that always capsizes. Thanks, Gimmelotsarobots

I think at this point in time of my life, ive lost my ability to create well designed weapons with knex. But Ive always been fascinated by the ball machines, and I would like to pursue further into my knex hobby to make them. But my skill when it comes to this is at rock bottom. I have no experience, and no concept on how to design anything for these. I also need to buy more parts to get started on it and be able to finish it without worrying about missing some parts. I havent gone anywhere guys, just had some time off since I couldnt make anything good. I miss all of you guys, and hopefully, I can get something going and youll see more from me :) -SW-

After years of just the Robot being the only Instructables shirt, we decided to make a small batch of a new design. It's simple and straightforward and, for me at least, sums up the experience of sharing project ideas. Right now they're only available in the store here. If people like them we may make more.

The "1st world" (that would be us) is infamous for its rampant and wasteful consumerism. Buy an electronic gadget with N times the power of the OLPC machine, then throw it away after two years (incidentally filling landfills with all sorts of questionable stuff.) Meanwhile, other parts of the world starve for technology.Do you think it would be possible to SLIGHTLY modify the design of 1st world consumer products to make it easier to reuse them (or parts of them) in devices conceptually similar to OLPC? I mean, consider the cell phone. Modern cell phones have cameras, flash card sockets, relatively high-res (but tiny) displays, relatively high-quality sound capability, low power consumption in standby mode, and radio based networking capabilities. It seems pretty close to an OLPC device to me (tell me an Apple iPhone wouldn't be an adequate replacement for an OLPC...)Why can't "we" convince a cell phone manufacturer to design the internals such that when the phones original life is over, it's guts can get a larger display and keyboard and new software, and become someone's computer or eReader. People are willing to donate their old phones to assorted worthy causes now; they might even be convinced to pay an extra $10 to purchase a phone that is MORE reusable. (or is it more expensive to do this sort of "refurbishment" than to build brand new machines?) Now that wireless headsets are common, it's not even necessary for a cellphone to retain a "phone-like" size and shape. Can I have a paperback sized combination cell phone and eBook reader that will have a second life as "just an eBook reader"?What would it take to make a cellphone reusable as the core of a general purpose computer?1) extend and standardize display interface to allow page-sized display.2) extend and standardize keypad interface to allow keyboard (?)3) internal software nearly completely replacible with a general purpose OS.4) inappropriate radio functions capable of being removed, disabled, or converted to more appropriate functions (ad-hoc wireless networking)Some of those seem like things manufacturers would be doing anyway, just to reduce their own costs. Creating a reusable cellphone core may be more a matter of documentation than anything else (and politics. Not that either is easy.)Next, what other electronic devices do you have that you're likely to be done with before they break? An MP3 player could use the same standardized display link and reprogramability as cell phones. Your LCD monitor could implement the other half (old cell phone plus old monitor = general purpose computer?) I don't think there's enough standardization in the desktop computers to reuse them; their complexity makes reuse too administratively complex, and they're probably too power-hungry anyway.The "maker" community already spends a fair amount of effort reusing "appliances" as general purpose compute engines; usually "improving" the product in its original application space, or getting cheap cycles from a product that failed and is being sold off cheap. Creating intentionally reusable electronics would feed that community some, but it isn't big enough to absorb ALL the discards of our quick-moving society. A lot could be funneled into putting technology where it couldn't afford to be before.(some quick Google use says:In the US, we throw away over 400,000 cell phones PER DAY linkIn Europe, 27% of mobile phone user buy a new phone every year link; only 5% of the old phones are recycled.Overall, less than 1% of cell phones are recycled. link; cell phone sales are expected to exceed 1 billion per year by 2009.)(I pick primarilly on cell phones because they seem SO CLOSE to being a general purpose computer, AND small enough to possibly incorporate into a larger "second life" product.)

I know the staff, and some members, are tired of hearing criticism of the recent changes the site has undergone. Some is probably valid, most is just knee jerk. I don't want to pile on, more than I already have, but after seeing the homepage today I have to say something. I've attached a screen shot of the current home page full screened on a 23" monitor. Lets say I'm visiting Instructables for the first time. Is a giant, scaling, Radio Shack advert really the only thing you want to show up? (Since the ad scales with the window yo would need a huge screen to be able to see anything else on landing, also if you aren't full screen it is literally all you see besides the header.) Sure there are a links to the categories but what if I'm new and don't know those are the categories or what they mean. What if I'm a regular but don't know what category the thing I'm looking for is in? Search you say, just use the search bar. Right, ok, just as soon as I find it. Oh you mean this giant thing in the middle of my screen that typed out like it's a non-usable flash animation when I first landed? What if I don't know what I'm looking for, lets call it browsing. Looks like there are some featured projects down below. *scrolls down* One project with a picture large enough to discern it's subject, three with shrunken down thumbnails, and 8 more in a wall of text with no pictures to give any context to the titles. This home screen is no longer a hub for the site. It's 50% add, 25% blank space, and 25% links to specific things. With the giant ad filling the entire screen the stuff below feels like it is tacked on as an afterthought. It really feels like it was designed around the ad. You have to know what you are looking for for it to even be remotely useful. Over 3/4 of the time if I'm am looking at a project on Instructables I found it by browsing ALL the categories, at once, on the old homepage. Unless I'm looking for something specific I'm not going to spend the time to click through every catagory just to see what's up. I have broad interests and jumping to 6 different pages just isn't going to cut it. It also makes it feel very disjointed. You go from a page with almost no content to a page filtered down to 1/6th of the sites content, at most. This isn't just bad for people browsing either, this will directly impact authors as well. With only one decent sized picture and only 4 pictures total what are the chances your project is going to make the front page? Average case I would assume people might click through half of the six categories in the current format. Right there that's a probable 50% drop in eyes even seeing your project, click through rates will decrease that number further but those could actually rise (as a percentage of the total people that see the project. This doesn't cancel out the first decrease though). A 66% decrease is also plausible and of course roughly 83% is worst case. If the browser doesn't win and the author doesn't win then who wins? Unless Radio Shack has paid for all the space on the top of the home screen, in which case the Autodesk balance sheet wins, nobody does. It causes me some concern that the reasoning given for the major format changes to the Instructables themselves was to really emphasize the pictures, and I believe the same ting was said about the previous homepage update, but now pictures of projects have almost entirely been removed. The motivation here is fuzzy at best. I would love to hear from someone on that staff that knows the actual reason behind the change. If it makes sense I'm willing to listen and adapt my usage habits but if this is simply a numbers game in the ledger book then this probably signals the end of me browsing other peoples projects. (Unless a staff member will actually come out and say it's a money grab in which case I appreciate the honesty and maybe we can all work together to find a way to generate more income. The last thing we want is Instructables to go under.) EDIT: Interestingly it's not as bad in IE8 (The ad that is. The lack of projects is still quite apparent) but there is a little issue with the scaling of the "search bar". Maybe the ad size is a bug, as there is at least one other FF bug already spotted, see below. Also the image comment system seems to have reverted to the old style click and drag, at least here in the forum. Maybe it nerev changed, I don't post photos here much.

We're about to break out a new channel for assistive/adaptive tech projects, and other "disability hack" type of Instructables. The big question: what do we call this channel, and what category do we sort it under? Why is this a hard question? Check out the Humana Health by Design contest entries - they include everything from ultra low-tech tools and life hacks to construction projects and full-on techie builds. Perhaps we need more than one channel. If so, how should we divide the Instructables? Do we need one channel for high-tech projects, and one for low-tech? I've been playing with the ideas of "assistive tech" for the high-tech/gadget-based projects to be filed under Technology, and "adaptive tools" for the low-tech/reuse projects and life-hacks to be sorted under Living. These still seem to be arbitrary distinctions, and I'm not sure they make sense. What do you think? Please discuss in the comments, or feel free to send me your suggestions by email/PM!

I am in the early stages of building a new Tesla coil. After over 10 years without one I think it is time to add one to my collection again ;) As always I want to stick to to the classic design, meaning except for the HV supply all will be home made, including the capacitor. No no fancy electronics, just high voltage, a cap and a spark gap... However, classic must not always mean there is no room for improvement. Of course you can measure or calculate the frequencies for your primary and secondary coil before even starting to power it up - but where is the fun in that?? My last Tesla coil was driven by a 2KW transformer delivering 25.000 Volts. This time I go smaller for indoor use and will aim for a simple neon sign transformer with around 3000 volts and 20-30mA output. Reason for this that I plan to make an Instructable out of it if I find the time and would prefer to use power supplies that can be obtained in most countries without totally blowing the budget. I did some research on the net to see if there are any significant developments but the only things I could find are in relation to the spark gap or to use a conical primary coil. For the conical coil I could not even find any comparison to standard flat coil in the same system or a decent explanation why it is claimed to be so much better. My aim is to go a different way for the primary completely. Instead of using copper pipe in a standard winding pattern I want to try a quadfilar coil instead. My early tests on a small scale confirmed that a bifilar coil is better than a standard coil. For some weird reson the magnetic field reaches further and is stronger while at the same time there is less loss. So far bilifar coils are only used on some charging pads and "wireless power supplies" for TV sets. In most induction cooktops, where the benefits would be extra obvious, they are not used due to the higher cost factor of producing them. Big question here is: Has anyone experimented with bifilar or quadfilar coils in high voltage applications and is willing share some insight?

After taking some time to get used to the new site design, I've decided that, overall, I like it a lot. It's cleaner and leaves more real estate on the page for the content when reading an Instructable. But. (you knew that was coming) When I read an instructable, I reach the bottom and usually want to go back to the Instructables homepage. This may not be the flow everyone follows when cruising the site, but it's what I do. The top banner scrolling away but leaving the 'ible info there as a "ribbon" is a neat trick, but I keep expecting to see a link to the homepage up there that will save me from having to scroll all the way back up to the top of the page. What i'd like to see is a "Jump to top" link, either at the very bottom of the Instructable, or in the "ribbon" where the title and voting, etc. reside. The "ribbon" would be slightly more useful, since I could click it when I reach the comments if I don't want to read them all. Again, it may just be me, and I'm not asking you to redesign the site just for me, but I find myself noticing it often enough that I thought it might affect other users as well. Thank you for all you do, editors!
