How to harness the energy in snow

I found a thread that asked this question previously on instructables but the author wanted to harness the kinetic energy of falling snow, and many of the criticisms involved the unpredictability of when snow will fall.I am specifically curious if it is possible to create a machine to remove snow that uses the energy of the snow itself. Ideally, it would melt the snow and use the water or steam to power itself.The things Canadian winters do to the mind...

Sam Browne belt/harness mods?

I want to make a modification to the classic Sam Browne belt/harness by adding a thigh bag to hold tools, water bottles, etc. I'm looking for a pattern to be made from heavy canvas or at least khaki denim. If anyone's been to an Army surplus store will probably get a pretty good idea of what I'm looking for. The bag has one large central pocket, two zippered pockets on the inside, and two outer pockets. It also has a large cover flap over the top with a leather or canvas tie-down straps.

How do I make a no-pull harness for my dog?

My dog pulls against his current harness constantly. We once borrowed a so-called 'no-pull harness' that worked brilliantly by tightening around and under his forelegs if he tried pulling, unfortunately it seems impossible to purchase one here so I was hoping to try my hand at making my own. You can see examples of the harness by performing a google image search.

How do you connect multiple wires together for a harness?

If you are creating an automotive type wire harness and need to connect the same ground to say six switches or relays, what's the best way to connect 6 short wires together to one longer wire that runs to GND or +?  I've tried multiple methods using soldering and butt connectors, but all have poor results.

Making your own custom plug for a wiring harness?

I have always wondered whether it would be possible to make your own custom plugs for wiring harnesses, similar to the ones used in automotive wiring such as in car stereos. The use of multiple wires is very common in projects, It would be much better to have wires organized into a harness with a plug rather than just multiple random spade connectors. My main aim is to use these harnesses for car add-ons for which wiring harnesses and/or plugs cannot be supplied. Thanks for all the help!

Convert an old canister vac to a harness/backpack vac?

Greetings Instructables Brethren! I've been getting along with all hardwood and no vacuum cleaner for 7 years now, and now with kids, I am admitting defeat, but still can't take that dreaded step into the spiral of ever-shortening planned obsolescence cycles for ever-more-expensive and flimsy junk. I'm looking for a way to turn an old Electrolux or other simple, repairable, and reliable antique canister vac, into a backpack vac. I wanted to do this Instructable myself, but between the 3 kids and being only armed with a dustmop and broom, I haven't got the time to do all the project development! Can someone out there with a few tools and a Monster Hacker / steampunk mentality, convert an old canister vac to a trusty Ghostbuster-style Backpack Duster? It will need a superlong cord, though most of those oldies-but-goodies did come with that.  And if you do this successfully, and can see fit to sell it on the Instructables Store, you probably have your first customer, right here!

How to harness waste heat from a gas hot water system? Answered

I have a outdoor gas hot water system in the courtyard of my rental property. So much waste heat blows out of a vent at the top of it, I want to harness this somehow but there is a sign on it that says specifically not to cover it. I was thinking about building a box type arrangment on top of it to use for drying clothes. Even beter would be a way to use it to heat the house as it is winter here in melbourne and freezing cold but. It seems like venting and flow is a bit of a complex subject. Anybody with any expertise here? Cheers (Edit: I have decided not to go ahead with this project as the amount of heat the water heater emits on standby isn't enough to worth bothering with. Thanks to everyone for their replies)

Can I replace a broken soldered-in DC jack on laptop, with a DC jack cable connector with harness? Please help!

This is for an Asus K53E laptop.  I tried to remove the bad dc jack, but I've given up.  Since I cracked part of the MB/circuit board where it is soldered in, I'd like to know if I can connect a dc jack that uses a cable harness instead?  I already have removed an ethernet port on the laptop, so I have a slot to insert a new jack.   My thinking, is that this would plug directly into the MB, instead of the plug that is soldered into MB, and then I can charge my laptop again!  My other option is to buy an external battery charger, but those run about $70 and the harness is only $12.   Is there anyone that can tell me if this will work?  Please?  :)

Rush å fikse Storbritannias Cyber politiet

Http:// Eksklusivt: TechWeekEurope FOIs utsette usammenhengende metoder i cyber politiarbeid over Storbritannia, som tjenestemenn begynner å slite over forestående dannelsen av National Cyber Crime Unit Når jeg spør Charlie McMurdie, leder for Mets politiet sentrale e-Crime Unit (PCeU), og hvis hun er bekymret for dannelsen av National Cyber Crime Unit, hennes hender dekke øynene i fortvilelse, halv-hånlig, halv-ekte. Hun vet at i de neste ni månedene, vil hun bli oppgave med å fullføre sammenslåingen av PCeU med cyber-arm av den alvorlige organisert kriminalitet Agency(SOCA), å danne Storbritannias bly cyber politiet troppen, NCCU. McMurdie vet dette kommer til å ta en monumental innsats, en som vil se slutten av PCeU, som hun hjalp satt opp i 2008. Hun er fretting over det faktum at NCCU ikke engang har et riktig hjem ennå, og heller ikke en sjef å lede britiske cyber politiarbeid inn i en ny epoke. Og hun engang vet ikke hvis hun vil fortsatt være politiarbeid cyber-kriminalitet på slutten av det hele. Britiske cyber politiet Men innsatsen kan godt være verdt det, for Storbritannias offentlige og bedrifter både. Det er fordi britiske politiarbeid av e-kriminalitet, på landsbasis, mangler i en rekke avgjørende områder. Frihet av informasjon (FSM) forespørsler sendt av TechWeekEurope til hver politistyrke i Storbritannia har avdekket stark forskjellene i registreringer av cyber-kriminalitet over hele Storbritannia. Metropolitan politiet, ikke overraskende, har sett de fleste handlingen. Det så en økning i Computer Misuse Act lovbrudd fra 11,181 i 2010 til 12,817 i 2012 (til November). Ennå ble 997 enkeltpersoner belastet, mindre enn i 2010, når 1291 ble belastet, eller 2011, da antall var 1262. Hvorfor nedgangen i kostnader når antallet lovbrudd har økt med over 1000 i London-området alene? Politiet, som har ikke klart å forbedre deres håndtering av cyber tilfeller de siste tre årene? Dataene kan indikere dette. Andre steder, ser politiet liten cyber-relaterte tiltak, i forhold til andre vanlige forbrytelser for eksempel innbrudd eller hærverk. Faktisk, det synes å ha jevnet i mange områder, mens bare en håndfull av personer har blitt fakturert de siste tre årene. I Leicestershire gikk Internett-baserte bedragerier ned fra 298 i 2010 til 167 i 2011 og 143 i 2012, opp til November. I Hertfordshire det ble bare 189 cyber-relaterte lovbrudd og 21 belastet fra 1 januar 2010 til 1 November 2012. Lancashire innspilt 19 Internett-baserte lovbrudd i samme tidsrom, seks under Computer Misuse Act. Bare ett ble belastet-de mottatt en fengselsstraff, men det involverte andre tilkoblede lovbrudd. Strathclyde rapportert 466 cyber forbrytelser i 2010, 543 i 2011 men så bare 143 mellom januar og oktober i 2012. Surrey har sett en nedgang i Computer Misuse Act lovbrudd, fra 45 i 2010 til 17 i 2012, og det har bare belastet en person. I alle FOI svar var det en nedgang eller meget beskjeden vekst i poster av cyber-kriminalitet. Det er til tross for indikasjoner fra mange kilder som viser Internett kriminalitet er på vei oppover. De siste tallene fra British Retail konsortiet viste totalkostnadene for detaljhandel kriminalitet i Storbritannia hoppet 15,6 prosent i et år. E-kriminalitet steg til å bli den mest kostbare av alle detaljhandel forbrytelser, regnskap for 37 prosent av totalt £1.6 milliarder tapt i ett år. I noen tilfeller, politiet utsette innspillingen av cyber-kriminalitet til nasjonale svindel intelligens Bureau (NFIB), men det gjør ikke rede for mangel på noen bemerkelsesverdige stiger i e-kriminalitet poster på tvers av britiske styrker. Usammenhengende politiarbeid Men hva alle disse tallene fortelle oss? De angir en nasjonal lappverk i cyber politiarbeid, hvor styrkene utenfor Met bare ikke har nok evne eller vilje til å opp sin innsats, sikkerhetseksperter mener. Kartet nedenfor høydepunkter denne lappverk, viser forskjeller i nivåer av cyber-kriminalitet og i kvaliteten på registrerer innen politiet styrker (disse styrkene ikke på kartet var ute av stand til å levere data): Se flere relaterte videoer og emner:

Walking LED Billboard

Hi Instructable Members! I was hoping someone can help me with a project for a business, which in turn will help others with their businesses or give ideas to other members. In this down economy, we need all the help we can get and rather than ask for a handout out from the government it is up to each and everyone of us to make our own way. Okay, enough of the preaching, let's get a teaching! My request is for information on constructing a internally lit, walking billboard. This is to advertise a walking tour business that I would like to start, but it could also be used to advertise other businesses. If you do a quick search on YouTube, you'll see a couple examples of what I'm talking about. Usually these models are pretty big and quite heavy, or should I say, heavier than they ought to be. I've seen them up close and have spoken to guys paid to carry them around here in Las Vegas. I'm told that they are constructed from sheet metal and plexiglass, weigh about 30lbs without the battery and aren't that comfortable. I wanted to make my units lighter and more comfortable, especially since I'll be the one wearing it all day. To do so, I've done a little research and have come up with some of the components to do this. Harness: I plan to use a military backpack frame called a Molle Frame. This is used as an internal structure to hold backpacks. It has several attachment points and is molded to follow the counter of the back. I have already purchased this harness along with the shoulder straps and hip harness. It is quite rugged and I'm sure it hold up to a 100 lbs in equipment. Though I hope my sign will weigh less than 10 lbs. Brace: To attach the billboard to the harness, I'd like to manufacture an aluminum brace. This brace would be constructed from aluminum bar stock and bent in such a way to hold the sign upright. It would be attached to the Molle harness by drilling holes through the aluminum bars and attached via nuts, bolts and washers. Cross braces will be attached to give the brace rigidity. Billboard Construction: (this is where I need help) Rather than making a "light box" from sheet metal, my idea would be to use Coroplast (a plastic type cardboard, typically used in mail containers like the post office uses. These can be found in sheets up to 1" thick. This could be used for the construction of a lightweight "light box" and then covered with black vinyl sheets or even spray painted. A rigid sign poster frame can then be attached to this box to hold a white opaque acrylic sheet. Then the advertisement can be place onto this sheet and then covered by a 3rd clear sheet to protect the advertisement. A quick note: This light box would have and internal skeleton, made of aluminum braces to attach to the brace and support the coroplast "light box" as well as the advertisement frame. Electrical component: (again, help is needed) I'm envisioning using led rope, or leds along the back side of the box to cast out enough light to illuminate the advertisement. Also I failed to mention that along the top of this light box, the front side has to be lit, as it will extend about a foot above my head to advertise toward the people i'm walking toward to. Please search "walking billboards" in YouTube and you'll see what I mean.;=related My unit won't nearly be as large, as I do have to be mobile and be able to maneuver inside casinos without knocking anyone over. So if you choose to accept this mission, I'd greatly appreciate it. Any ideas will be taken under advisement and if they seem to be doable and cost effective, I'll put up the results as a LED Walking Billboard Instructable - Let the creativity flow and the designing begin! Sincerely, ~Elric Leano
