Power assited dolly

Could someone recommend a dc motor strong enough but @ the same time gentle enough to be used for power assist. The item will be a custom built dolly used for lugging around camera equipment. The total weight will be approx. 50 - 75 lbs. Thank you to those that help.

Minimalist marine battery dolly? Answered

Hi. Been lugging around a 38 lb. marine battery (9" x 9" x 5.5") that cannot be stored in the kayak.  I hate walking long distances with it. Need something like a compact luggage cart, but very minimalist.  Would like to store the carrier with the battery while on the water, in the kayak storage well.  That way it is readily accessible. Thinking just a 1/4" plywood "L" shape that hug the battery bottom and back. I cannot think of how to make the "L" joint (where 2 pieces come together) strong. Also, need suggestion for a (telescopic?) removable handle. Do I use an axle?  Thanks much for any suggestions.  This will be a big help!

Best way to convert motor power to wheel power? Answered

I have a dolly cart and motor, and I want to motor to move the dolly cart as slowly as possible (It's already four RPM, but just take that into account in the method you recommend). I need one of the inner/vertical wheels to be spun by the motor. Both the cart and the motor are pictured below. I am using this for time-lapses, so it should be as consistent as possible. What is the best way to connect the two parts so the motor spins one of the wheels?

WHAT'S A BETTER WAY TO MOVE SUCH A HEAVY ITEM UPSTAIRS?

Isn't moving a ~300 lb refrigerator up flights of such stairs very DANGEROUS? .. I know of catastrophic resulting injuries.. I'm thinking of a few design improvements; and wonder if others are too.. Besides the obvious (pictured) need to add good ratchet straps, and a larger dolly, my designs range from better muscular force use, to mechanization....  Also,  can anyone please inform here about gripping, one-way, or ratcheting pulleys?..

How to connect caster wheeled dollys in series so they rotate around corners for pullable parade float

I connected moving dollys with a D Ring screwed to on ends and a dog chain clasp in middle connecting a 1/4 between the dollys with same D Ring and swiveable dog clasp to hold light weight plastic tree designs for a float but the 1 by 4 doesn't stay level. I am trying to figure out how to connect a one by four between two moving dollys with pivot points so that I can navigate around corners for a moveable parade float that connects a series of these. I am stuck mainly on the middle one by four not staying level and toppling over. . Anybody make something similar on here? or have ideas? I want to be able to dismantle this and transport in a car or a truck.

Stop motion camera crane

Ok. I need to create a camera crane. It dosn't have to be very big since I'm using it for stop motion. Just a simple pan and tilt crane with a counterweight to off-set the camera. Now, I can make a regular one very simply using a video crane method that you can find on this site. However, this crane must do 2 things. 1. It must be able to move at incredibly small increments. Only fractions of an inch at a time. 2. The crane must be able to hold it's position in a very sturdy manner. It cannot move even in the slightest because stop-motion requires that the camera does not move at all while individual pictures are being taken. For the life of me, I can't figure it out. Traditionally, a "step motor" is used to create the individual movements for things like this. But they are incredibly expensive. I've had more luck with gears and servos, however I want to figure out the logistics before I just go buy gears individually on a website that may or may not work. Your help would be appreciated. Thank you.

Help loading a wide load onto a narrow trailer?

I'm looking for some ideas on how to get a small 1940's AC Combine (farm machinery) onto a trailer without having to dismantle it.  It weighs about 3000# so not too heavy but the 2 wheels are about 104" apart (wide) so they won't fir onto a normal deckover style trailer (96" wide).  Once I can get it on the trailer, I plan to set it down on blocks and chain it down.  The problem - how to get it ONTO the trailer. Seems I have 2 options - 1) rig up something to make the ramps and trailer wider (just for loading) OR 2) rig up something with wheels that will bolt to the axle BUT be narrow enough to fit onto the trailer ..... sort of like a dolly.  Option 2 presents a bit of a problem in making sure the "dolly wheels" clear the combine's axle since they'll be underneath it. Thanks for your advice/ideas.

What can I use to drive 7 x 2w 5cm speakers?

Hi all, I'm making a sound installation using 7 of these speakers: http://www.rapidonline.com/Audio-Visual/5cm-Mini-speaker-with-plastic-diaphragm-73504 I need to output sounds (just stereo, for now, I have no idea how I would run a 7 channel set up) from my soundcard on my laptop which just has fairly standard outputs i.e. phono and jack. I'm not sure what I need to bridge these two things, obviously you would usually use an amp but these speakers are only 2w so I was thinking they probably don't need a proper amp. Also most amps don't have enough outputs for 7 speakers. I need whatever it is to be as small and cheap as is possible. Thank you in advance! Dolly x

Building ideas for a onstage train? Answered

My high school is doing Hello Dolly and if possiblelwould like a train to be brought on stage, does anyone have ideas on how to do that? I have a couple but I'm having trouble bring all of it to one idea. I had an idea you can make hand turnable axles and gears for the wheels, other stuff for the smokestack, I was thinking maybe corflute for the body, but its really just chaos in my head right now. Any suggestions?  It needs to be fairly lightweight.  It would be nice to have workable wheels  And not a real smokestack obviously but the appearance of smoke and a whistle Maybe a back platform if at all possible that Dolly could jump on... Our stage is small. It has no special things about it and its roughly 20 by 30 feet. There are two backstage wings that are really just small hallways that let out into the audience, and those are about 20 feet long.  Our plays are all financed by the drama teacher herself so the less expensive the better as well.  If nothing comes up thats ok too. We have an alternative that can be used.

Voltage regulator for trailer brakes

Im planning on building a motorized trailer dolly for my travel trailer, however i want to make a dead mans switch for the trailer brakes.  I was wondering if I took apart an old cordless drill if I could use the trigger as a voltage regulator to regulate the voltage to the trailer brake system.  Without getting into specifics of how it will connect to the regulator, I figure I would have like a bike brake handle that while applied the trailer brakes would be off, but if released that the trailer brakes would be applied incase the trailer started to roll away from you. Any suggestions other than "Go buy a trailer brake controller" would be appreciated! :)

Custom furnishings and home items for people that can't bend over.

My mother has recently developed a kidney issue which causes a severe level of pain whenever she tries to bend over.  We basically need some ideas on re-outfitting the house with better possibilities so she can easily get to her household items without too much discomfort.  She is a stubborn one, and we will catch her writhing in pain before she asks anyone for help.  Because she will try to do these things anyway, we would like to make it alot less painful for her.  It is hard for her to get things out of her bottom cupboards.  I've been envisioning a pull-out platform with a round hole for her cane where she can insert her cane and pull the platform out and grab what she needs, but it would be even better if somehow this stuff could actually come up to her at a standing level.  My mind doesn't quite wrap around it.  I've seen an instructable for her to get things down from the top cupboards and I'm considering trying these out.  We also need a way for her to feed her pets, to set the dogfood bowls down onto the ground and retrieve them without pain.  I was picturing sort of a dolly-looking thing with a crank so she can forklift things up and down to herself.  I can see some of what we need in my head but I don't have the mechanical skills to put these things together.  I'd appreciate seeing some instructables of this nature or geared toward solving these types of problems. Thanks! If you see anything that may be use for me, please post a link and I will also share my findings.

FAQ: How Do I Search Instructables?

20080605. I exchanged a few PMs with Eric and it seems that even the Instructables staff is not sure about what's going on with the search feature. So ... until they can get this all straightened out, Eric recommends that we use the "site:www.instructables.com" option on Google for advanced searches. The Lucene search should work for most simple searches.. From Google's Web Search Help Center: "You can use Google to search only within one specific website by entering the search terms you're looking for, followed by the word "site" and a colon followed by the domain name. For example, here's how you'd find admission information on the Stanford University site: admission site:www.stanford.edu. Eg, "NachoMahma site:www.instructables.com" will search for my username on this site.. Try Kiteman +Law site:www.instructables.com.. . Sorry for any confusion I may have caused. . Instructables uses the Lucene search engine. I'm still trying to figure a lot of this out (can't seem to get +/- to work right, for one). As I gain insights into what is going on, I will share them here.. This is a Work In Progress and may probably contains many errors. Use at your own risk, but I can't imagine any of this causing any harm - the worst it should do is generate an error message.. Some Lucene features may not work at Instructables - I'll erase those as I become aware of them.. If you know of any search tricks or tips, or can provide any insight as to how all this works with Instructables, please PM me (or leave a comment). I'm open to all suggestions.. The following is from Lucene Query Parser Syntax (copyright 2006 by The Apache Software Foundation. Distributed under Apache License, Version 2.0). About all I've done, so far (2008-06-01), is format it for Instructables. Any info I've added is noted in the text.. Note: I can't figure out how to escape a carat (formatting code for superscript), so I've substituted "/\" (slash + back-slash), except in the pre-formatted examples.Table Of ContentsOverviewTermsFieldsTerm Modifiers (Wildcard Searches, Fuzzy Searches, Proximity Searches, Range Searches, Boosting a Term)Boolean Operators (AND, +, NOT, -)Grouping (AKA parentheses - nacho)Field GroupingEscaping Special CharactersTerms. A query is broken up into terms and operators. There are two types of terms: Single Terms and Phrases.. A Single Term is a single word such as "test" or "hello".. A Phrase is a group of words surrounded by double quotes such as "hello dolly".Multiple terms can be combined together with Boolean operators to form a more complex query (see below).Fields. Lucene supports fielded data. When performing a search you can either specify a field, or use the default field. The field names and default field is implementation specific.. You can search any field by typing the field name followed by a colon ":" and then the term you are looking for.. As an example, let's assume a Lucene index contains two fields, title and text and text is the default field. If you want to find the document entitled "The Right Way" which contains the text "don't go this way", you can enter:title:"The Right Way" AND text:goortitle:"Do it right" AND right. Since text is the default field, the field indicator is not required.. Note: The field is only valid for the term that it directly precedes, so the querytitle:Do it rightwill only find "Do" in the title field. It will find "it" and "right" in the default field (in this case the text field).Need to get a list of fields used on Instructables. - nachoWildcard Searches. Lucene supports single and multiple character wildcard searches within single terms (not within phrase queries).. To perform a single character wildcard search use the "?" symbol.. To perform a multiple character wildcard search use the "*" symbol.. The single character wildcard search looks for terms that match that with the single character replaced. For example, to search for "text" or "test" you can use the search:te?t. Multiple character wildcard searches looks for 0 or more characters. For example, to search for test, tests or tester, you can use the search:test*. You can also use the wildcard searches in the middle of a term.te*t. Note: You cannot use a * or ? symbol as the first character of a search.? and * work just like DOS wildcards, except you cannot use them as the first character - nachoFuzzy Searches. Lucene supports fuzzy searches based on the Levenshtein Distance, or Edit Distance algorithm. To do a fuzzy search use the tilde, "~", symbol at the end of a Single word Term. For example to search for a term similar in spelling to "roam" use the fuzzy search:roam~. This search will find terms like foam and roams.. Starting with Lucene 1.9 an additional (optional) parameter can specify the required similarity. The value is between 0 and 1, with a value closer to 1 only terms with a higher similarity will be matched. For example:roam~0.8. The default that is used if the parameter is not given is 0.5.Proximity Searches. Lucene supports finding words are a within a specific distance away. To do a proximity search use the tilde, "~", symbol at the end of a Phrase. For example to search for a "apache" and "jakarta" within 10 words of each other in a document use the search:"jakarta apache"~10Range Searches. Range Queries allow one to match documents whose field(s) values are between the lower and upper bound specified by the Range Query. Range Queries can be inclusive or exclusive of the upper and lower bounds. Sorting is done lexicographically.mod_date:[20020101 TO 20030101]. This will find documents whose mod_date fields have values between 20020101 and 20030101, inclusive. Note that Range Queries are not reserved for date fields. You could also use range queries with non-date fields:title:{Aida TO Carmen}. This will find all documents whose titles are between Aida and Carmen, but not including Aida and Carmen.. Inclusive range queries are denoted by square brackets. Exclusive range queries are denoted by curly brackets.Boosting a Term. Lucene provides the relevance level of matching documents based on the terms found. To boost a term use the caret, "/\", symbol with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more relevant the term will be.. Boosting allows you to control the relevance of a document by boosting its term. For example, if you are searching forjakarta apacheand you want the term "jakarta" to be more relevant boost it using the /\ symbol along with the boost factor next to the term. You would type:jakarta^4 apache. This will make documents with the term jakarta appear more relevant. You can also boost Phrase Terms as in the example:"jakarta apache"^4 "Apache Lucene". By default, the boost factor is 1. Although the boost factor must be positive, it can be less than 1 (e.g. 0.2)Boolean Operators. Boolean operators allow terms to be combined through logic operators. Lucene supports AND, "+", OR, NOT and "-" as Boolean operators(Note: Boolean operators must be ALL CAPS).The OR operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the OR operator is used. The OR operator links two terms and finds a matching document if either of the terms exist in a document. This is equivalent to a union using sets. The symbol || can be used in place of the word OR.. To search for documents that contain either "jakarta apache" or just "jakarta" use the query:"jakarta apache" jakartaor"jakarta apache" OR jakartaAND. The AND operator matches documents where both terms exist anywhere in the text of a single document. This is equivalent to an intersection using sets. The symbol && can be used in place of the word AND.. To search for documents that contain "jakarta apache" and "Apache Lucene" use the query:"jakarta apache" AND "Apache Lucene"+. The "+" or required operator requires that the term after the "+" symbol exist somewhere in a the field of a single document.. To search for documents that must contain "jakarta" and may contain "lucene" use the query:+jakarta luceneNOT. The NOT operator excludes documents that contain the term after NOT. This is equivalent to a difference using sets. The symbol ! can be used in place of the word NOT.. To search for documents that contain "jakarta apache" but not "Apache Lucene" use the query:"jakarta apache" NOT "Apache Lucene". Note: The NOT operator cannot be used with just one term. For example, the following search will return no results:NOT "jakarta apache"-. The "-" or prohibit operator excludes documents that contain the term after the "-" symbol.. To search for documents that contain "jakarta apache" but not "Apache Lucene" use the query:"jakarta apache" -"Apache Lucene"Can anyone compare/contrast AND/+ and NOT/-? - nachoGrouping. Lucene supports using parentheses to group clauses to form sub queries. This can be very useful if you want to control the boolean logic for a query.. To search for either "jakarta" or "apache" and "website" use the query:(jakarta OR apache) AND website. This eliminates any confusion and makes sure you that website must exist and either term jakarta or apache may exist.Field Grouping. Lucene supports using parentheses to group multiple clauses to a single field.. To search for a title that contains both the word "return" and the phrase "pink panther" use the query:title:(+return +"pink panther")Escaping Special Characters. Lucene supports escaping special characters that are part of the query syntax. The current list special characters are+ - && || ! ( ) { } [] /\ " ~ * ? : \. To escape these character use the \ before the character. For example to search for (1+1):2 use the query:\(1\+1\)\:2. That's it. All corrections and/or clarifications are welcomed.
