E- walker idea ?

Hey All- I’m the new gal on the block - not round it , so I thought I'd skip proceedings and get to the main point why im here ( aside from the fact I like to learn more , meet people and of course take over the world ) The problem then , and it is big problem , is that I have disability and so Im looking at way I can get around better than I have been . One of these ideas of late has involved basically using something called a knee walker , which you can see here[url]http://www.phc-online.com/Knee_Walker_p/neebop-785.htm[/url] , and trying to adapt it so I have electrical asssitance / power for rought terrain , typical paths here and steeper hills. To add to this problem is the fact I know nill , not even the basics really ,of how I should go about this , other than other examples of what people have done and seem feasible . I don’t have have soldering kits, milling machines or any of that stuff for cutting adapting frames , and TBH would rather try to avoid if i can , simply because I dont want my knee walker too look much like a DIY job / unprofessional and therefore not the credible disability device it currently is. Speed is not issue , I guess 4mph is fine , though it would be nice to go a bit faster for more difficult ground I.e. even off road . The tires I think I can replace with moutainboard given their the same size , ( provided wheelbase checks out ) and the battery has to be ideally be lithium I.e. as opposed to lead. I don’t really mind whether its 2 or 4 wheel drive but figured ( because the axle is all sealed off on both sides ) a hub motor might be the only way of achieving this idea. Any way, that’s just about it , I still need to take the wheels off to confirm the wheel base but other than that , I cant think of much more to say. If any one has any suggestions then on how a complete beginner could make this idea a reality I’d really appreciate . Thanks a lot helena

Motor Help for Horse Walker

Hi ppl,Somewhat just agreed to help a friend and his family build a 'horse walker'!I know sounds weird but they want to have a go at building one rather than buying one. Basically as none of them know about electronics they asked for my help.....And now i ask for yours......Now i assume that the motor will run from mains, will have to be pretty beefy, if anyone has ideas on this please link me!Next, speed control, i can probably acquire a relay module from my dad (electronic engineer) and program a micro processor to turn the motor on and off for set periods of time to exercise the horses. Whats the best way of getting speed control?Thanksdrummerianhttp://www.show-jumps.co.uk/horse-walker.jpg

Help for completion of Knee Walker Project ?

Hi Everyone I have a problem with a project I started to overcome my unique disability , this project was to basically install low powered electric motor on a kneewalker so I could get assistance / go off-road , yet still use it manually if need be i.e. to get some exercise or more importantly if battery dies ( something I cant do with mobility scooter or wheelchair  ) The problem however is I cant do this myself due my disability ( weld it , use power tools etc ) so I had this person i meet on a another  forum who agreed to help me - but unfortunately he hasnt   - so instead I am trying to find a replacement for him or any one that is willing to help. The motor itself ( Motor - MW12B GoldenMotor  )seems to work fine using a Lyens controller , but  unfortunately there is no direct link to the hub motor whose details are below. Model: MW12B -- 12" Motor Wheel Voltage:36V (Brushless) Power Rate:250W Weight: 4.8Kgs You will have to got to the gm website on the link above click on hub motors and scroll down to find more details , including links to 3d drawings . You can see the motor itself working in following videos that were posted by the person who still has it video1 video2 video3 Due to the size difference of the wheel  ( 16" compared to the front 9" using MTB tires ) amongst other things, we were  trying to find a way to mount it that he suggested would probably involve having to weld on some strong rear forks from a bike  or perhaps something else. Ive included the whole assessment / plan we did based on our mutual ideas and discussions below for reference, but Im afraid thats pretty much it , as I dont have any of the parts here for reference or than the basic facts . If any ones interested in helping , or going me any advice Id be grateful for your suggestions , if any ones wants to offer their services at a price just send me a pm and we discuss things further. thanks for listening , heres the assessment / plan I mentioned.. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- I need to figure out a rough plan for the wheel mounting, plus brake mounting. We need to get disc and caliper. We need to figure out what front wheels, how to mount them, and how to fix the sloppy steering. In order to go see a welder we need to know where to weld the dropouts, the caliper mounts, and what, if any welding to do at the front end. Assessment Frame - good, solid, heavy. bulletproof. Wheels - strong, solid, better made with bearings etc better than expected. but hard tires are not nice, and wheels are a little too thin and too small. I expect its easy to get hung up on small obstacles. brakes - crap. none existent basically. Just a bit of metal pushing on the tyre. Also the lever is either crap or a bit broken. need to inspect it. steering - not very good but not crap. whole linkgae is a bit loose and wobbly, just held together by a few bolts. this means it has a fair bit of play in the steering. The whole thing with the bolts is that they have to be a bit loose otherwise the steering won't move. not a very good design. but it will do. handlebars/stem/steerer - designed to be collapsible easily, which is good, but there is also excessive play in this as well. it will do but its not great. ------------------------------------------------------------------ Thoughts.... Because there is four wheels, I found that on uneven floors (just around the front room the floorboards were uneven enough) one wheel is often off the ground a tiny bit. This would be solved by having 3 wheels or tyres with a bit of give in them. I would not want to keep any of the wheels. I would want to replace the front wheels with something a bit wider softer and grippier. like scooter wheels or MTB wheels. Brakes - the center of gravity is quite far forward. if it had brakes only on the front then i feel like it might tip over. then again, with the weight of the frame, the motor, batteries and person, maybe not. I will do some testing. Motors - Golden has the 8" single sided solid tyre motors that would be the easiest conversion, but I don't like the solid tyres and I don't like having 2 wheels at the back. I already ran into my foot. There is also the 8" double sided solid tire. This is not so easy either because it is the same size as the existing wheels therefore the axle would want to go exactly where the existing axles join. Could be done with cutting and welding but would be a pain, plus you still have the solid tire etc. I held up a 12" dinner plate and I reckon it would not look so bad actually. I will take some pics tomorrow. It looks like we would need to cut off a bit of the back section and weld on some dropouts, a bit higher up and further in than the existing axle mounts.. It looks like it will fit under the knee platform ok as well. Controller - because we may well end up with a motor that is not exactly right for the job, I think its all the more important we get a controller with some intelligence. Something programmable where we can set a low voltage, top speed etc. This leads us back to the GM controller, Lyens mini monster, or......I just thought, hmmm the kelly controllers are programmable - well they do a little controller that might be up for the job as well. In fact it looks the most programmable one so far. It is the mini one next to the coke can here: Hub & Wheel Motor Controller | EV Parts They have one that does 12-24v for $79 or $99 depending on max amps. You can get it waterproof for an extra $19 http://kellycontroller.com/kbs2405120a1 ... p-499.html It is fully programmable, see the software screenshots and manual here: Kelly KBS controllers online demo/help-Kelly Controls, LLC http://kellycontroller.com/mot/download ... Manual.pdf You need a serial port on your computer to program it, if you don't have one you need a serial to USB converter. They sell one for $29. Kelly are good controllers. I never thought of them until just now - I usually associate them with high power controllers for cars and motorbikes. When I used to work at Sevcon (who make argubaly the best...and most expensive...controllers you can get.)....kelly was one of the few competitors we kept an eye on. If you look at the setup software, you can fine tune min throttle, max throttle, max amps, max speed, all kinds of things. It will be just the ticket for fine tuning. --------------------------------------------------------------------- So........... This would be my personal plan right now - Electronics: $115 Motor - MW12B (GM) $98 kelly controller waterproofed $29 Serial RS232 to USB converter (from kelly) $20 throttle (max) $20 ebrake lever (max) $50 wiring, connectors, etc -------- $332 Frame / Fabrication: $50 old steel bike to steal dropouts off (maximum, probably less from craigslist or a garage sale) $150 to pay someone to weld the dropouts on and maybe brake caliper mounts plus machine front wheel mounts if necessary for new wheels (maximum) $50 (max) 2 front wheels MTB or scooter 8 inch with pneumatic tyres. $30 (max) new axles, bolts, washers etc $30 box for battery plus mounting bolts etc $50 (max) for respray or powdercoat frame (will be messy after welding. something to put the battery in ----------------------- $360 Brakes $20 (max) brake disk for rear plus screw on adapter for rear hub Brake discs $40 (max) brake caliper (cable ok, hydraulic not needed) $50 bolt on brake caliper mount (seen them somewhere but can't find right now) price is a guess. --------------------------- $110 Battery depends. I am clueless as to the requirements of this system. I can test with my own batteries once it is setup. Then we will know, but at a minimum you will be talking about 18 or 24v 10 amp hour. That is : $199 from ping

Help needed to upgrade wheels on walker for all-terrain ?

I've been trying to source a rim / hub  for my e-walker project , and so far havent been succesful  in finding the exact measurments I need  7.5 " wheel / 46 mm width with 9- 10mm bearing ( SEE BELOW ) http://www.mcmaster.com/#ball-and-rolle ... gs/=9i3dx1 The spacer inside the wheel based on my measurements is 2.7 mm in length and 13 mm in diameter ( outside ) Any way , it seems the best match I can find for hub , tire so far is one of those wheels used on those razor electric scooters  here  though I do not see any bore sizes for any of them, in spite of being told there are after emailing them that its up there ( you can see for yourelf if you like ) So instead, I did websearch on the model of the scooter that correlated with the sorta wheel specs that might work - like e100 razor  and found 8mm mentioned a few times , which I assumed might be the correct diameter of the axel / bore size i need. ( I have also asked on scooter forum to confirm this ) 8 mm however is too small to fit my own  knee walker mobility device , so I was wondering - to cut a long story short  - if there is any way I can enlarge the hole in the bearings that might be realtively easy i.e. without paying someone else ( assuming this could be done easily ) or having to buy a rim with a bigger bore and using some sort of hub ring to make u the difference ( perhaps a bad idea for hun motor ) Again , if any one has any suggestion they willing to share I'd be more than greateful for your ideas and badly needed advice  :) thanks once again. hele

Johnny Walker Game caller wont work properly

Guys(and gals) i need help once again. While I was looking in my friends garage i saw a Johnny Walker game caller and these things are expensive so i asked him about it and he said it didnt work. So ofcourse i offered to try and fix it, and he said if i can that i can use it anytime. (and if you have a good memory, you will remember the post i made about how to make one of these game callers) Well, its power supply is 12 volts DC, 2 6v batteries ran in a series. and they are rechargeable by the way. when i plug the recharging plug(you dont remove the batteries to recharge, there is a port right under the place for the cassette) and hit the power button the red LED(that signals power) is at full strength for about half a second then fades to a wimpy red color. at the same time the LED is at its full power there is a noise coming over the speaker and the noise dies once the LED dims. Any suggestions?

Final Fantasy 6 magitek armor!

Hello, fellow instructables members! I was looking over Bug's steampunk chicken-walker mecha, and I had a most awesome idea. From the final fantasy game that screams "steampunk", I remember the cool walker mechas, the 'magitek armor'. See where I'm going with this? I plan to make a chicken-walker style Magitek armor costume! Now, I doubt my mecha will do the magiteks any justice, and I've never quite made a complete "costume" myself, save for a mashup medieval style outfit (makes me think of ike from fire emblem). So, if anyone has input, especially anyone who does steampunk, I'm all ears. Also, thank you again to the user "Bug" for the inspiration!

Walker/Rollator/KneeScooter type of DIY varieties for knee problem

Hi I am totally new here but have used the search so need your help. I have knee problems. But needs something other than a standard Walker/Rollator So I looked on youtube and google for kneescooters or rideons and Balance Bikes. The reason is that I need something to sit on. A KneeScooter is ideal for that kind of thing. Them are like a knew walker or knee rollator but one sit on them instead. So why don't I just buy the best of them and just love it :) Well them are on the wrong continent. I live in and are a native of Sweden which is Northern Europe in case you wonder. We don't know about such high tech over here. Sure we have same "assisted" Scooters like you have. Like sitting on a three or four wheel Motor Scooter but electric instead of Gasoline. Heavy things you can not take inside unless you buy the coolapsable that is rather neatly made. Anyway I don't really need motor assist I do have muscles so I can pedal a bike but bikes are not allowed inside the Mall and get stolen outside the Mall. Bikes are frown upon on the communal transport like Bus or Commuter Train and such. A Rollator or a Wheeled Walker is allowed everywhere so what I need is a KneeScooter that looks and behaves like a standard Wheeled Walker/Rollator but that one can sit on and ride like a Balance bike for kids. I can try to link to or upload drawings later how I have tried to envision what such would look like or function. So to conclude. It should appear to the Guards, Security Persons at the Mall like any standard Rollator. But then outside when them look away you touch a few buttons or something and it transforms into this handy BalanceBike but for grownups that allow me to push and kick myself striding or riding along but without pedals or motors. Dimensions maybe at most a yard = some 3 feet length and width maybe at most 2 feet and height adjustable for individual length of legs. So it should change between two positions or functions. Like a Rollator Wheeled Walker and then change to a Balance Bike or toddlers bike without pedals so it should be caster wheel as a Rollator but steerable front wheel as a Balance Bike.

device that applies braking force proportional to speed?

Hi, I'm helping a team of students make a brake-assist device for a two-wheeled walker.  We were wondering if there are mechanical brakes out there that apply a force proportional to the speed.  A circular damper, is how we would describe it, I think.  Or something like a gas shock (the things on screen doors and car trunks) but with a circular motion rather than a linear stroke.  Anyone have any ideas?  Anything that's commercially available, small, and somewhat inexpensive is fair game.  Bonus points for things that can be made by hand..  Thanks!

MGS5's iDroid - Can it be Built with Open Source Tech?

I can't get enough of Metal Gear Solid 5! It definitely deserves the 10/10 scores its received! But as cool as it would be to have a giant robot or even a Walker Gear that you and/or your enemies can pilot, I think the coolest thing to have from the game would be the "iDroid". If you havent played "The Phantom Pain" or "Ground Zeroes", the iDroid is a device Snake uses for multiple purposes. Some include: sending radio trasmissions and calling in supply drops or helicopters between the iDroid's location and Mother Base, Displaying a topographical satellite view of the area Snake is in, Organizing Mother Base staff, resources, R&D; projects, and playing music from cassette tapes found while on missions, Just to name a few. (bold font is to differentiate the uses) So is it possible to build a similar device using the open source technology of today? (minus the use of cassette tapes and a 2D holographic projection screen) I'm pretty confident that it can be done, but what do you guys think?

But as cool as it would be to have a giant robot or even a Walker Gear that you and/or your enemies can pilot, I think the coolest thing to have from the game would be the "iDroid". If you havent played "The Phantom Pain" or "Ground Zeroes", the iDroid is a device Snake uses for multiple purposes. Some include: sending radio trasmissions and calling in supply drops or helicopters between the iDroid's location and Mother Base, Displaying a topographical satellite view of the area Snake is in, Organizing Mother Base staff, resources, R&D; projects, and playing music from cassette tapes found while on missions, Just to name a few. (bold font is to differentiate the uses) So is it possible to build a similar device using the open source technology of today? (minus the use of cassette tapes and a 2D holographic projection screen) I'm pretty confident that it can be done, but what do you guys think? (btw i also have the same topic in the Tech section, cuz i figured that would fit well probably)

your opinion about the movie district 9

OK i just went and heard the whole plot of Neill Blomkamp masterpiece the Monalisa of movies D9. he was supposed to make the halo movie but Microsoft was complaining its multimillion dollar A$$ off so Neill felling sad thought up remixing his movie Alive in norunburg i think its called. so here this movie is a unsuspecting antagonist "Wikus van Der Merwe" is doing a documentary on MNU moving the Aliens to district 10 but he then goes into a shack and is screwing around with items of none of his concern and sprays a crap-storm virus in his eye that mutates his arm to a alien arm and changes his DNA so he can operate alien machinery MNU being the bastards they are jacks him up and takes him to there base for dissection he then daringly grabs a scalpel and holds a doctor hostage leading up to that he escapes to district 9 where he meets Christopher who at first is reluctant to kick Wikus's A$$ they soon befriend each other they then steal some alien weaponry and launch a counter attack on the MNU mercs were he retrieves a fuel cell to power a ship were Chris finds out that MNU have been experimenting on his people later on Wikus finds out that it would take up to 3 years to turn him back to a human,then a Emnite shamalan twist pops up Chris wants to go home for help before coming back to cure Wikus he then gets angry and kicks poor Chris's A$$ and powers up a ship were his engine is shot up and he crashes he than crawls out. soon cute Christopher's son Little CJ gains control of a mechanized battle suit from inside the crashed shuttle and helps free Wikus, Wikus then enters the alien walker battle suit and defends Christopher as the mother ship uses a tractor beam to lift the shuttle on board.he shuttle docks with the mother ship, Wikus is shot in the back and the walker suit ejects him after taking critical damage. Wikus drags himself away from the leader of the mercenaries, but is unavoidably caught. Just before the trigger is pulled, four aliens burst out of the surrounding slums and rips apart Wikus's attackers.The film concludes with another series of interviews and news broadcasts, showing the humans view on the events that unfolded. An interview with Wikus' wife reveals a small metal rose was left on her doorstep (one of Wikus' trademarks, he strongly believed a gift is worth more if it was made personally). She concludes it couldn't possibly be Wikus, no one has heard from him since he was last seen crawling from the mangled battle suit. An alien is then seen standing in a junk yard inside District 9 fashioning a small metal rose out of scrap metal, implying that Wikus is alive, his transformation from human to alien is complete, and is still awaiting Christopher's promised return. just tell me what you think about the ending

I got a siren!

A little over a month ago, my dad got a siren on eBay. It's the Wolo Model 345, about halfway down the page. Note: if you want one, go through eBay, Wolo wants $64, but this was brand-new for $20. It's not Instructable-worthy, and I don't have enough pictures to make a Slideshow, so I'm using the Forums for their original use. We were originally going to put this on my mom's ZAP Xebra, because it's completely silent and we wanted a way to warn walkers of her approach, but she didn't like it, so I got it to put in out Ford Courier. Since it's electric, I only go 39 in a 40 mph-zone to save range, so I'm often cut off by people going 45. Being electric, the truck has no radiator, just a flat plate of steel. We were already going to paint it black, so we mounted the horn speaker in there. There is an instrument bay overhead, so I stuffed the control box inside an empty slot. Eventually I'll take off the plastic case and mount it in the aluminum sheet to make it much cleaner, but this is fine for now. There were already two extra switches that did nothing, but already had an always-hot line running to them, so I wired it in to that. It can do sirens, animal noises, or a PA. I'm leaving it set to a police-style siren, so if someone cuts me off, I can just flip the switch and give a short blast, then watch them look around for the police car. If I have more time, I can just use the PA to yell at them. Other potential use: I'm going to make a CD of engine sounds. That way I can make my electric sound like an idling Harley at a stoplight. Or a turbine engine. Or a semi. Or a whatever.

Cabins/shelter from garbage/recycling and then some- new site/blog- and INDIE BOOK released

D.I.Y. Micro-Shelters: NEW indie book-forum/site- w/cabins from garbage/recycling and then some I figured it was about time to get up off my arse and get an actual account here, as on a few other sites I constantly(!) read. I'll also post a few of the "constructed-from-roadside-trash" cabins I've built soon- here and on my own blog/site (if anyone's interested, if not, I'll resume beer drinking, and general relaxation). I'm also in the process of building a 16 square foot multi-purpose, mobile cabin-sleeper/sauna/greenhouse/ice-fishing shanty that I'll eventually post upon (its one of three cabins in the works in my Sanford N' Son-like backyard)- yeah, my wife is a trooper! http://www.relaxshax.com http://www.relaxshacks.com In the meantime, after WELL over a year of illustrating and writing, I've now finally completed (through tiny yellow house press) my own small houses/cabins book "Humble Homes, Simple Shacks, Cozy Cottages, Ramshackle Retreats, Funky Forts- And Whatever The Heck Else We Could Squeeze In Here." Clockin' in, coffee-table-book size, at just over 100 pages filled with avalanches of sketches and redneck-thrift/yankee ingenuity projects and ideas, I'm now selling a small initial run of these hand assembled books (you can find all the details on the blog/post). Building your own windows, doors, solar showers, rainbarrels, bridges, furniture, and more from recycled crud, is all covered within. Inspirationally, the books owes good parts of its existence to the work of Lester Walker, David and Jeanie Stiles, D.C. Beard, Dan Price, and Lloyd Kahn. All in all, I'm a small-house book junky, and after the well started drying up a little (I've bought and read all the decent ones I could find) I decided to write my own. Anyway, thanks for looking, and I'll get some small house photos up soon! Happy belated new years to all! -Derek "Deek" Diedricksen

Halloween Photo Contest Winners

Thanks to everyone for all of your awesome entries in the 2012 Instructables Photo Contest. We had over 600 entries, and our 11 judges just delivered their final evaluations. This was our biggest Halloween contest yet, and it was only successful because of each and every participant’s contribution. From everyone at Instructables, thank you so much for sharing what you’ve made. Instructables helps to set the tone for DIY Halloween costumes, and you guys all set the tone for Instructables. Keep up the great work, and I cannot wait to see what you put together in 2013. (Just 11 short months until Halloween!) This year’s first prize in the Halloween Photo Contest is Tatterhood’s Ryuk Costume. Her project was an excellent example of what we look for in a photo entry: namely, a series of great pictures that illustrate the project’s creation along with enough explanatory text that the project is reproducible to some degree. This project in particular did an excellent job of telling a story in photos and mortaring any gaps in detail with the text. Plus, it is awesome. The leather outfit, the mask, and the feathered shoulders would have each made a great project. Taken together, this was an outstanding project (even if you’re unfamiliar with the Death Note reference material.) Our second prize winners were wonderful as well. There wasn’t a terribly sharp drop-off from first prize to second prize, which speaks to the amount and quality of the work poured into each of these projects. Rexrothwell's painstakingly detailed White Walker, a TMNT group costume (with Splinter!) from wmorey37, and davisgraveyard's weeping angel monument that wouldn’t look out of place in a cemetery or on Dr. Who round out our second prizes. Third prize winners: you will each receive a mold cutting, prop polishing, versatile Dremel rotary tool to help you unseat this year’s winners in 2013. Do not be disheartened by a third place finish, since a few of the folks who won larger prizes used professional photographers, are professional prop or costume makers, or just plain spent more time or money on their entries. Final note: Consider competing with a step by step project next year, as documentation and reproducibility are important considerations when comparing excellent projects against other excellent projects.
