repairing cellar walls?

 We bought a house last year that had some water damage on the cellar walls. Last summer I redid the drainage around the house as I suspected that that was the reason for the damage. I am now setting out to repair the inside damage. I should not that I noticed no damage to the outside walls while redoing the drainage.  The inside wall damage consists of 'blistering' and loose light cement/plaster. The cinder blocks seem to be fine and I have not found mold. I have scraped away the loose stuff and will now patch the holes.  I have been told to use a polymer-based household cement but would like to ask the instructable community for advice.  I basically have to resurface parts fo the walls and patch a few deep holes.  How should I do this? Thank you.

Cycle Skates

I once read that technology never dies.  There are people today that still make flint knives and start fires by friction.  Furthermore, these skills have been passed down generation to generation.  To prove the hypothesis, the authors got an old Sears Catalog from the 1890s and picked out two pages of stuff they had never heard of.  They found all of them still available for purchase somewhere. Why then, can I not find the Cycle Skates in this 1923 video?   https://www.youtube.com/watch?v=UjtPn4orR9A They were apparently invented in 1870. (http://pedespeed.blogspot.com/2007/07/following-is-from-leonard-de-vries.html) I cannot find the patent info as they seem to be from France. I know in 2004 someone "re-invented" them as Chariot Skates.   Anyway, I would like to learn how to make my own 1870 / 1923 style cycle skates.    Anyone out there who can help?

Disconnected Wires

So I'm working on a heart sensor, and pulled out the wires. I think I can fix it with a  little bit of solder, because after 20 or 30 minutes of negotiating, i can usually re-establish the connection to the sensor. But I tried just now, and it isn't working. Help??

MP3 Bedtime Stories ..... Battery supply???

Hi, new here so please bare with me.....long story cut short. My Grandson is five years old and I thought it would be great, and get him to sleep quicker at night, if I could come up with some method of playing MP3 stories. I know, CD player, etc. nope, at five years old they want to take EVERYTHING apart. So no mains leads, CDs, etc. What I came up with was buy a simple and cheap (£2.99) MP3 player off ebay, pair it with a small battery powered speaker (£5.99) and away we go.....doh!   Both items are amazing and just right for the job BUT both are battery powered (will go flat after he falls asleep and they are left on) and two, they both have on-off switches underneath which stops me mounting them on a surface. Sorry this is going on so long....... What I thought of doing is getting a loooooooong lasting battery source (would 9v last a lot longer) and bringing ing it down to 1.5v (x2 one feed for each device). Then it wouldn't matter if they were left on overnight a few times -  or am I deluded.  Or better still, can anybody please advise?

Instructables member map

Sometimes we find a project that we’d like to actually see and touch. Other times we have resources (components, equipment, etc.) that we’d like to give away or barter for help with another project. This website is an excellent resource to build up a community of makers. Also, 5 years ago I posted a project requesting help and I haven't received any answers, yet. I think that part of the problem is that not everybody reads the forums. In many cases, when we see a project that we'd like to develop, not knowing where the maker is located dissuade us to pursue such project. I think that we need to develop a reference map showing the city or town where we are located. That way we could develop more synergy and by doing that, increase our resourcefulness and benefit all members. Don’t you think so? P.S. I’m not a computer guy, but I understand that for some of you the Google API is not a problem.

At Camp, Teens Blow Stuff Up, As They're Told

While some teens use their summers to learn sailing, archery or soccer, Brandon Meadows attends Summer Explosives Camp in Missouri to learn how to use dynamite."Some people like baseball, others like math -- I just like to set off bombs," he said. "I figure here, learning how to do it properly is better than messing around with it at home, right?"Meadows is one of 20 teenage campers enrolled in a weeklong explosion camp in the Missouri Ozarks. At the camp, high school students from as far away as Egypt and Hawaii shoot dynamite, TNT and plastic explosives.The camp's leader, Paul Worsey, a professor at the University of Missouri, Rolla, uses the camp as a way to attract new recruits into the unglamorous field of mine engineering. He recruits students to help carry on the industry, which is facing a serious personnel shortage."It's critically important," Worsey said. "These are our workers to sustain this industry going forward."So far, the camp is working. Meadows has already enrolled in the explosives engineering program at the University of Missouri at Rolla for next fall. http://www.npr.org/templates/story/story.php?storyId=11226636

Instructables Book

We've published a book of Instructables!Order your copy of The Best of Instructables Volume 1 here!See the latest news about The Best of Instructables Volume 1 here.I just got the contract worked out with O'Reilly Media/MAKE, who is publishing the book. Details are still being finalized, but the book will look something like this: 75 (maybe?) full Instructables and 50 (maybe?) mentions (author, intro image and text maybe?) of Instructables in a community-choice section. The Instructables in the community-choice section will be chosen by a month-long contest open to Instructables published at any point in the past. The top Instructables by votes in the contest will be included. The full Instructables will be chosen by the people at Instructables, the O'Reilly and MAKE editors, and using the results of the book contest. If your project is selected, we'll ask for your permission and give you a free copy of the book. We're hoping to have it out in time for the Austin Maker Faire in October.These details are likely to change, but I'm so excited that I wanted to share them even at this early stage. We'll do a formal announcement when we know more, so consider this your sneak-preview. Updated: Number of full Instructables from 100 to 75. 2008-07-03 Update: Right now, it looks like we'll be including approximately 50 Instructables in the community choice section of the book as chosen by our Instructables Book Contest. This section will have 8-10 Instructables per page and each Instructable will have the author, title, intro text and image. Everyone mentioned will receive a free copy. As usual we'll be eliminating fraudulent votes.75 full Instructables will be included as chosen by editors at Instructables, MAKE, and O'Reilly. Obviously, we'll be watching the results of the contest closely to make sure we didn't miss anything!Since print and internet are such different mediums, part of the selection process is finding Instructables will exceptional images and well-written text. Since any Instructable can be included, now is a great time to make sure your images are top-notch and maybe add a few more, if you can. 2008-09-01 Update: If your Instructable is in the top 50 sorted by user votes, you are definitely in the community choice section. Depending on how many of those 50 are included as full Instructables in the book, the community choice section may include more Instructables. We are working hard at getting everything organized and ready for the book launch in October.

Circuit Scribe Build Night at E4D Banjarapalya

Greetings, Just like our previous build night with circuit stickers, this build night with circuit scribes was a huge success. Many participants of our rural Banjarapalya Makerspace participated and built cool artistic projects. Although most projects were made on paper, it brought out the amazing creativity of these kids who are mostly first time learners of computer and English. Some projects: Photo sensing iron man face, blinking house, blinking E4D, Light house, Hulk face. We hope to do many more of such build nights in the months to come, introducing our village to some amazing and fun tech.  Cheers

Minimalist survival kit help

I'm looking at a new prospective for a survival kit. I have an I.N.C.H. bag that i use camping. While I can pack it down to almost nothing, I dont use many of the bigger items. I was looking for ways to essentially minimize my bag. While I'm experience with the great outdoors, the minimalist aproach is a relitivly new concept to me. I want to base the kit on the ten essentials. I live in a harsh enviroment so I'd likely not be changing my shelter much. The shelter is already pretty basic.  This is my must-have gear: Map, Compass, Sunglasses, Extra clothing (a skivvy roll and what I'm wearing plus my hoody and ponchos), Illumination (Preferably no batteries), First-aid supplies, Firestarter, Matches, Knife and Extra food. My current sleep system is as follows: Medium Weather sleeping bag with compression sac, Compact collapsible cot, Goretex bivvy sac, Sleeping role and Grommeted space blanket. I'm more worried about weight than size. I will likely switch the cot for a hammock because it's pretty sizey and the metal rods make half the weight of the system. For food I was thinking keep my hobo stove and boyscout mess kit but im considering adding a hobo fishing rig. My current fishing kit is a multi function compact pole with a fly reel and spin cast reel. While very light weight it takes up some space. About 1.5'x8"x4" roughly. any ideas on additions or subtractions for the kit? I'm mostly trying to reduce weight. I'm strong but lugging around a ruck sack takes more than a simple backpack with this and that.  Any ideas are apreciated. I don't need a whole lot to live comfortably in the woods. The picture is of my I.N.C.H. bag pack in to my freighter frame. The black box is the fishing kit, the blue sac is the cot. Inside the pack is the sleeping bag bulging out. It's Probably my biggest item and in this pic is not in its compression sac as the sac was 'misplaced' while moving. I guess I'm asking for advise on downsizing the I.N.C.H. bag...

Band, Miter, jig or scroll saw: the "goto" tool

Hi, I was wondering what people use for prepping materials to fit on small workspace spaces. I am interested in using machinable materials like acrylic, lexan, delrin, hdpe, machinable foam, polystyrene, brass and aluminum. These materials are usually easy to get in the right thickness and width, but the length could be 4'. I need to slice them down to sizes no more than 5.25" long to be used on a small cnc machine (5.5"x4.5"x1.25" build area) What do you think, or have experience with, that solves most of your needs?

This renewable energy source will use a magnetically levitated vertical axis wind turbine with single phase permanent magnet alternator made by our team. There will be 3 stationary wind guide vanes/flaps of concave shape on the outer periphery of turbine. These vanes will be controlled by dc gear motor for constant wind flow and protection against high speed winds. Using perturb & observe MPPT algorithm on DC-DC boost converter, constant DC voltage for GRID integration is made. A lower energy Bluetooth module will send data on user computer about whole system parameter, hence making the whole system to be smart and hence data is saved in database. https://www.youtube.com/watch?v=fC5hYLjhO9U

Good Software For Planning Builds

Does anyone know any good software to help with planning builds? Any type of building type software or such, for small projects. I guess 3d modeling is probably what a lot of people use, but it seems like it has a steep learning curve from what I've seen. I was hoping maybe there is a much simpler modeling program out there for, example,  just throwing a quick box/chest together with dimensions etc.

Nexus 7 (2013, Gen2, FLO) - internal micro SD mod

With games getting bigger and bigger with every new release and limited storage capacity some of you might think the same: Why not add a SD card to my Nexus 7? The lates Lollipop update basically killed the normal USB OTG funstions, so if you do want to use a USB stick or external SD card in a reader you will need a powered USB OTG cable. I am not sure if this was intentionally or another bug but it is damn annoying. After openeing my tablet to check m options I realised my main problem is space. Even adding a micro SD with a similar small reader is a major pain as there simply is no empty space left inside. So I was hoping someone here might be interested in such a mod and contribute with good ideas during the build and maybe even copy the mod (if I manage it) to confirm it is in fact doable. My findings so far: A custom rom is a must have due to the OTG limits of the original. It might be enough to just find a suitable kernel but so far I settled for the Team UB Lollipop release. It offers some mods based on Cyanogen and claims full OTG support. Other roms also added support for external WiFi and TV dongles, so there is room to play. As said space is a problem I am working on ;) For an internal mod and due to the lack of physical support on the mainboard the only option is to use the standrad USB port for this mod. This means SD, reader and OTG mod must fit inside somehow. It also means some sort of physical switch is required for the times when you need full power during the recharge - although I have to test if this still works with an external SD while the tablet is switched off. In that case I could accept 500mA charge during normal use and 1A or more when the tablet is switched off. The rom should support fast USB charge but I am not sure if this olaso works in host mode. It is possible to use some extra app and scripts to make good use of such a mod. Not only can you use the SD for music, movies and other demanding files but with scripting you can also move the big data files from games to the external storage. Works similar to the apps you can get for devices with a real SD card, where you often find the "Move to SD" option in the app manager. This mod will not be for the faint hearted as it requires serious soldering skills on these tiny components, so if you only know how to solder copper pipes you might need some training on old electronics first ;) Let me know what you think and if you would be interested in such a mod as otherwise I won't bother taking pics during the progress. And without pics there will be no Instructable follwing ;)

I am making a POV (persistance of vision) project using atmega8 ,which is being programmed by arduino (uno) as ISP i am following this tutorial videos and blink led code is working well   for me as in the video, I tired the same code by changing the delay for verifying whether the circuit works properly  and i was working nice But i uploaded my persistance of vision code(POV) its no working   none of the leds is blinking I using the correct pin i verified it with arduino uno atmega8 pin mapping Here is my Persistance of vision code int _[] = {0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0}; int A[] = {0,1,1,1,1, 1,0,1,0,0, 0,1,1,1,1}; int B[] = {1,1,1,1,1, 1,0,1,0,1, 0,1,0,1,0}; int C[] = {0,1,1,1,0, 1,0,0,0,1, 1,0,0,0,1}; int D[] = {1,1,1,1,1, 1,0,0,0,1, 0,1,1,1,0}; int E[] = {1,1,1,1,1, 1,0,1,0,1, 1,0,1,0,1}; int F[] = {1,1,1,1,1, 1,0,1,0,0, 1,0,1,0,0}; int G[] = {0,1,1,1,0, 1,0,1,0,1, 0,0,1,1,0}; int H[] = {1,1,1,1,1, 0,0,1,0,0, 1,1,1,1,1}; int I[] = {0,0,0,0,1, 1,0,1,1,1, 0,0,0,0,1}; int J[] = {1,0,0,0,0, 1,0,0,0,1, 1,1,1,1,1}; int K[] = {1,1,1,1,1, 0,0,1,0,0, 0,1,0,1,1}; int L[] = {1,1,1,1,1, 0,0,0,0,1, 0,0,0,0,1}; int M[] = {1,1,1,1,1, 0,1,1,0,0, 0,1,1,1,1}; int N[] = {1,1,1,1,1, 1,0,0,0,0, 0,1,1,1,1}; int O[] = {0,1,1,1,0, 1,0,0,0,1, 0,1,1,1,0}; int P[] = {1,1,1,1,1, 1,0,1,0,0, 0,1,0,0,0}; int Q[] = {0,1,1,1,1, 1,0,0,1,1, 0,1,1,1,1}; int R[] = {1,1,1,1,1, 1,0,1,0,0, 0,1,0,1,1}; int S[] = {0,1,0,0,1, 1,0,1,0,1, 1,0,0,1,0}; int T[] = {1,0,0,0,0, 1,1,1,1,1, 1,0,0,0,0}; int U[] = {1,1,1,1,1, 0,0,0,0,1, 1,1,1,1,1}; int V[] = {1,1,1,1,0, 0,0,0,0,1, 1,1,1,1,0}; int W[] = {1,1,1,1,0, 0,0,1,1,0, 1,1,1,1,0}; int X[] = {1,1,0,1,1, 0,0,1,0,0, 1,1,0,1,1}; int Y[] = {1,1,0,0,0, 0,0,1,0,0, 1,1,1,1,1}; int Z[] = {1,0,0,1,1, 1,0,1,0,1, 1,1,0,0,1}; int letterSpace; int dotTime; void setup() {   // setting the ports of the leds to OUTPUT   pinMode(2, OUTPUT);   pinMode(3, OUTPUT);   pinMode(4, OUTPUT);   pinMode(5, OUTPUT);   pinMode(6, OUTPUT);   // defining the space between the letters (ms)   letterSpace = 6;   // defining the time dots appear (ms)   dotTime = 3; } void printLetter(int letter[]) {   int y;   // printing the first y row of the letter   for (y=0; y<5; y++)   {     digitalWrite(y+2, letter[y]);   }   delay(dotTime);   // printing the second y row of the letter   for (y=0; y<5; y++)   {     digitalWrite(y+2, letter[y+5]);   }   delay(dotTime);   // printing the third y row of the letter   for (y=0; y<5; y++)   {     digitalWrite(y+2, letter[y+10]);   }   delay(dotTime);   // printing the sspace between the letters   for (y=0; y<5; y++)   {     digitalWrite(y+2, 0);   }   delay(letterSpace); } void loop() {   // you can print your own text by modifing here :) printLetter(H); printLetter(E); printLetter(L); printLetter(L); printLetter(O); printLetter(_);   } Is there any solution ???

And I was having the most fantastic day......

Really I was, I got into work, and had no real tasks to accomplish since my mentor was home sick and his boss was sick. Except she was so sick she asked me to do her job. So I got to spend 9 hours escorting 4 PE's all over to different locations. Climbing on roofs, crawling through mechanical rooms. digging things up, getting wet and dirty, all while trying to maintain a professional appearance.  I loved it!  I can't even express how much I love going to work, being an engineer is awesome. But then I got home to discover a microburst had hit our neighborhood. And was filled with anticipatory dread as I noticed the 65 foot oak in front of my house was no longer visible over the neighbors roof line. Well, the pictures below speak for themselves, there was only one way this thing could fall and NOT hit something, and it fell just that way. And if I hadn't been home late from work, my much loved truck would have been right under the trunk.

Shallow depth of Field... From a tiny lens?

It is a nice effect to open up the aperture of a camera, focus on the subject, and allow the background to go blurry.  But many of today's still and video cameras have a tiny aperture. How can I get shallow depth of field from such a camera?

Image annotations running off of image, not displaying

Image annotations are being lost either by being below or beyond the edge if the image they relate to. This has only happened since the new image display system was implemented. The old image system allowed annotations to run below and of the side of an image, where as the new one crops the text to fit only over the image. The old image annotation system also wrapped the text after a number of characters, where as the new system allows text to run on indefinably  Users can manually insert line breaks in the annotations with the new system (not possible with the old system), however for old instructables this introduces the problem of annotations running off the image and being unreadable. This appears to be on every instructable, providing there are annotations on the images, and the annotations are long enough, or positioned such that they run past the edge, or bottom of the image. An example of this is: https://www.instructables.com/id/Cat-enclosure-with-high-cat-walktunnel-utilizes-/ On this instructable there are examples of both running of the edge of an image, and falling off the bottom. It also shows an exception to the problem, the first image allows the annotation to go beyond the boundary of the image, but all subsequent images have the issue.

where does electricity go?

I got a question. If we ground everything to the Earth for shorts and things like that, Where does that electricity go to? Does it just disappear deep down inside the earth? Does GE have an electrical well and is sucking all this electricity that people pour onto the ground? Please dont use big words like anode and cathode and coulombs (simple is better) :)

Can drawings be used in part to show a "how to" for an instructable

I designed and created "hang on back" (like many aquarium filters) rock sculptures for my aquariums.  There were so many steps and my hands a mess that after starting to take photos (to show on aquarium sites) I stopped taking many of the photos (would require a lot)... but I did take some and as well the rock sculptures in various aquariums. Is it alright to do drawings or cut and paste schematics (need to show how I cut the plastic which I can not do now where I am at - so would a drawing be alright?)   to show certain steps? Thanks for any assistance.  I would like to enter the Pet contest?

Ski / Snowboard Simulator/Trainer

Hi, I've always wanted to figure out a way to build my own ski/snowboard simulator to help teach my kids(and others) how to snowboard. In our  & case, give them refreshers since they know how to snowboard and they're only.  My 17yr old daughter, on the other hand, that's another story. She hates snowboarding because she can't grasp it, so this would be good for her too.  Here are some links to give you an idea of the type of simulator I am referring to: http://www.youtube.com/user/virtualsnowmthigh http://www.youtube.com/watch?v=BqXRR2pTD4U&feature;=player_embedded#at=169 http://www.youtube.com/watch?v=1ZDeyYq5pyY http://www.virtualsnowoc.com/action.html

Mauser C96

Greetings, So, ever since I saw Chuunibyou, I've wanted to try my hand on a Mauser C96. Once again, it's a model, based heavily on Aug5om3's version. I built his one, then changed the handle, trigger and shortened the barrel a bit. The handle is a bit less sturdy than I like, but it looks pretty IMO, though the front of it could use some more curving. It features: - a comfortable handle - charging handle - moving hammer - pretty good looks I'm not entirely happy with it, but as I have plans for other builds, I decided to take some photos to share, and then take it apart. Posted it as a forum topic, as it isn't original enough to warrant a full slideshow. Tell me what you think in the comments!

Or just laugh at the annoyed faces of grammar pendants as you watch Steven fry shame them.  Now recently I made an instructable, it was named and "Breathe new life into an old computer" and being the grammar illiterate person I am, combined with the fact the article was written out of pure boredom, I misspelled the article title in two different places. Instead of "Breathe new life into an old computer" I wrote "Breath of new life into a old computer". The reason is, after writing the article, I felt the original title of "A breath of new life into a old computer" didn't really sound good. So I axed the A and called it a day (Rhyme not intended). It was late and without another thought I hit publish and eagerly awaited its appearance on the new ibles page. Nothing happened for 20 minutes, so I went to bed without a second thought. Maybe the database server just crashed or something :P The next day, after a long day of school, I eagerly sit down at my computer and watch youtube... After enjoying at least a few hours of Pwediepie screaming at disfigured goats and Linus (attempting) to colour a $500 motherboard I decide to check my Instructables page. A few clicks to my current Instructables page and WOAH. I see the featured banner draped proudly across the front of my project. My eyes dart down, desperately looking for a view counter and then they find it, "10 thousand views!" I cry. My mouse cursor automatically clicks, my world in slow motion, I scroll down... 3 comments greet me. I just sit there, mouth wide open. A crazy thought slams right into my face, my mouse cursor waddles over to the corner of the screen and suddenly the homepage sits there, my project stands in its little box, like an expensive toy, on display for all to see. My mind is racing, In disbelief. I look around, a hidden camera maybe, I shout upstairs to my brother "good prank". But all I hear is a surprised moan, "what?!" he shouts.  It took me a few hours for anything, whether it be ME being featured, or the chicken I had for dinner, to sink in. But eventually it did and I took a some rotting fleshes advice, Keep Calm and Carrion. The last thing on my mind at this point was spell checking, no one in the comments had pointed anything out, and well... I couldn't see anything wrong. It's like that thing when you're looking for something in that horrific mess you call a fridge, after spending what seems like hours looking at every little detail you still can't find the butter. Then your girl friend, Wife or Mum comes along and after giving you a lecture on tidiness they find that one thing you're looking for instantly... Anyway, I decide in the spirit of things I will go and enjoy some facebook, I take a trip to the Instructables facebook page and see my article, AWESOME! I open up the comments section and... Correcting my grammar Correcting more of my grammar I'm not an English professor Correcting my grammar Correcting my grammar Someone who doesn't understand that: 1. I am not American, 2. Americans are smart and awesome people Correcting my grammar Someone who uses such bad grammar that I can't even figure out what they are saying   Now at the sight of this I quickly ran back to my article and changed the picture and title, on facebook... It doesn't update. I have learned my lesson, proofread and double check your article, before you post!  What can you take away from this? What I have learnt:  Theres no 'Be Nice' policy on the internet Proofread your work! Admins are humans and might not pick up on a spelling mistake Write every ible like its the best one you have ever made, because you never know, your ible might be featured down the road and you will just wish that you double checked that title and fixed that little spelling mistake. Also dont ever use facebook because :( it dosnt update live :P lol The Facebook Post My Instructables

Option for no auto-formatting

In my recent instructable I was *more than slightly* annoyed that the new editor does simply not what I want it to do. Seperating the Text from some calculations with a blank line? Adding a few blanks to shift things a bit in? Nah, authors don't need that anyway, do they? But we want that! If we put a hell lot of work into quality projects, pictures, writeups, we want to be at least able to do the layout the way we want. Sure, if you're a pro everything can also be done by editing the html code, but the code generated by the editor is compleatly unformatted and definitly not intended to be read or modified by humans. So pleeease do something about this issue. It really bothers me. - nqtronix PS: It does work well in this editor, so where's the issue?!

Unable to follow someone

I don't seem to be able to follow contributors any more :(  On my PC, I'm using I.E 10.  I've cleared the browser cache, and explicitly added the instructables site to always allow cookies (which are turned on anyway).  I've also logged off and on several times.  If I click on a the follow button, it briefly displays the 'UNFOLLOW' option and the windows timer mouse icon, before reverting to 'FOLLOW' again.  On my Android phone, I have the Instructables app.  It allows me to follow someone, but does not add them to the list of people I already follow.  Is there a limit on the number of people I can follow?  I'm currently following 24 contributors.  Can you help please?

Instructable was featured but never appeared on the home page

I published an instructable yesterday (https://www.instructables.com/id/How-to-fix-earbuds-that-have-lost-their-rubber/) and received an email saying that it had been featured. It has the little "featured!" Banner over the icon, too. But it never appeared on the home page. I checked "explore --> featured", and found five or so instructables that were featured around the time mine was that never appeared on the home page, either.  I don't know if is is an actual bug, or if things are just done differently now.
