Hacking the Used Car Purchase « carsabi Paleo diets, polyphasic sleep, jail-broken kindles – if you recognize these you’re probably a hacker, and we’d like to share some tricks to do with automotive purchasing that we’ve gleaned from looking at about 20,000 dealership and classified car listings daily. Even assuming you don’t habitually optimize (hack) what other people take for granted, car hunting is important enough to be worth serious attention. We’ve used our search database to come up with five hacks that should save you both money and sanity on your next purchase. Shopping on Craigslist will save you at least $2,000 on most vehicles; the ubiquitous Toyota Corolla has median savings of $2,854 (916 datapoints, all clean title) with other models summarized below. In perhaps an obvious corollary, dealerships make money by purchasing your car at a lower price than they can sell it for. Do yourself and the community a service and let your old car go at a reasonable price. Happy hunting!
KondensKompressor. Destiladora solar-Goteo solar Kondenskompressor es una técnica que produce agua destilada con radiación solar. Es un sistema muy simple y eficaz que produce un “goteo solar” mediante el cual se puede reducir el agua de riego 10 veces respecto a sistemas tradicionales. Solo deberemos reutilizar unas cuantas garrafas de plástico. ¿Qué es el goteo solar? El goteo solar conocido también como KondensKompressor, es un sistema que atrapa el agua evaporada de la tierra y del depósito que hay en el interior gracias a la energía solar. La humedad condensa por las paredes interiores y cae en forma de goteo solar dirigido por las paredes otra vez a la tierra. El sistema permite ahorrar enormes cantidades de agua para el riego como cultivar plantas que necesitan para su crecimiento la mejor calidad de agua, se calcula que el riego solar puede reducir las necesidades de agua de riego hasta 10 veces comparado con otros sistemas tradicionales de riego. ¿Cómo se fabrica un Kondenskompressor para aplicar la técnica de goteo solar?
quand l’économie devient collaborative Outillées par Internet et par le Web qui permettent à des inconnus distants d’entrer en relation, de partager, et de coopérer, elles ouvrent des perspectives inédites d’évolution de nos modes de consommation, de production et de création. Elles constituent une invitation pour les entreprises à revisiter leurs modes d’organisation, leur innovation, leur relation à des clients devenus acteurs et leurs modèles de partage de la valeur. Orange, en tant qu’acteur majeur de cette économie informationnelle, s’intéresse à ces transformations émergentes, qui constituent à la fois des défis et des opportunités. Le rapport "Synthetic overview of the collaborative economy”, coproduit par Orange Labs et la P2PFoundation dresse une cartographie fouillée des acteurs de cette économie coopérative : pour la première fois, quasiment toutes les composantes de cette économie collaborative en émergence et leur interactions sont présentées dans un seul panorama.
Engine control unit An engine control unit (ECU), now called the powertrain control module (PCM), is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (called lookup tables), and adjusting the engine actuators accordingly. Before ECUs, air/fuel mixture, ignition timing, and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means. One of the earliest attempts to use such a unitized and automated device to manage multiple engine control functions simultaneously was the "Kommandogerät" created by BMW in 1939, for their 801 14-cylinder aviation radial engine.[citation needed] This device replaced the 6 controls used to initiate hard acceleration with one control in the 801 series-equipped aircraft.

Power from the people 17 October 2011Last updated at 03:41 By David Cohen Technology Reporter The biofuel cell, uses glucose and oxygen at concentrations found in the body to generate electricity. Plugging gadgets into a socket in the wall, or loading them with batteries - or maybe even unfurling a solar panel - is how most of us think of getting electricity. But what about plugging them into your body? It may sound far fetched, but under the shadow of the Alps, Dr Serge Cosnier and his team at the Joseph Fourier University of Grenoble have built a device to do just that. They are the first group in the world to demonstrate their device working while implanted in a living animal. Biofuel cells could kick-start a revolution in artificial organs and prosthetics that would transform tens of thousands of lives every year. Batteries are good enough for implants that don't need much power, but they run out fast, and when it comes to implants, that is more than just an inconvenience, it is a fundamental limitation.
Autour des pratiques collaboratives Pour la première fois de son histoire, notre société est confrontée à la gestion de l'abondance. La création, la contribution, l'expression de millions de personnes est "maintenant sous la main" (M. Serres). Pour bénéficier de cette abondance rendue possible par le numérique, il nous faut apprendre non plus à cacher notre copie, mais à réutiliser, partager, enrichir, et échanger en réseau. Voici une collecte de références pour se former, échanger autour des pratiques collaboratives initiée par Michel Briand, Telecom Bretagne, à compléter (wiki ouvert). Pour faciliter cette transition vers un monde du numérique ouvert et en réseau ouvert,nous faisons ici le choix des biens mis en communs en privilégiant les contenus, réseaux qui se place sous le signe du partage et des droits d'usage élargis. Une bibliographie complémentaire du magazine contributif "Pratiques Collaboratives" qui relie et diffuse initiatives, réflexions et contenus autour des pratiques collaboratives. Fil d'actualité
OBDII HOWTO Your car's mind is small and designed for readability, so don't be surprised how easy it is to see what it's thinking. Introduction If your vehicle was manufactured after 1996, it contains an On Board Diagnostic (OBD) computer that captures information about how it's running. OBD II is version 2.0 of the standard for communicating this information. The data tracked by the OBD II system was originally intended to monitor the engine's emissions and track down problems that caused cars to pollute more than normal. Since the data's transmission format and content are standardized, a number of third parties have developed hardware to detect and display these codes. Purpose The OBD II port allows your car to report three kinds of information: Diagnostic Trouble Codes (DTCs), real-time data, and freeze frame data. DTCs are simply error codes that can be looked up to determine what problem your car is experiencing. Real-time data is the raw sensor data reported to the OBD computer. The Standard Data
MIT stacks solar panels like pancakes, increases their power output by up to 20x What’s better than one pancake? A whole stack of pancakes! Using the same logic, a team of MIT researchers have stacked a bunch of photovoltaic solar cells together to produce up to 20 times the power output of conventional solar power installations. Normally I’m the first to drop my jaw in awe at MIT’s latest and greatest innovations, but this one really is a bit of a no-brainer. Basically, photovoltaic cells themselves aren’t all that expensive — according to MIT, they’re only around 35% of the total cost of a solar power installation. To combat this issue, MIT has built 3D stacks of photovoltaic cells. Squeezing more power out of low-light periods is a huge, huge deal.
Ces agriculteurs et ingénieurs qui veulent libérer les machines Et si on créait une civilisation en « open source » ? Un monde sans brevets. Des objets, des appareils, des machines, reproductibles à l’infini par tous ceux qui le souhaitent, grâce à la diffusion « libre » de leurs plans. C’est ce que propose Marcin Jakubowski : ce jeune diplômé de physique nucléaire, habitant du Missouri (États-Unis), devenu agriculteur-bricoleur, cherche à constituer et diffuser un kit de 50 machines industrielles – tracteur, bulldozer, moissonneuse-batteuse, four, éolienne, moteur hydraulique, bétonnière ou machine à compacter des briques de terre – pour bâtir, en toute autonomie, l’infrastructure d’un village. Ou les bases d’une civilisation ! Le principe est simple : il s’agit de fabriquer artisanalement des machines industrielles, à très bas coût (en moyenne 8 fois moins que celles fabriquées industriellement), et d’expliquer à ceux qui le souhaitent comment les reproduire eux-mêmes. Recensement et adaptation des outils, réalisation et diffusion des plans
Protege5 I thought it would be easier than it actually was. This is not a HOWTO guide. It is a HOWI guide. In other words, it's not how to install your AC adaptor. Before you undertake a project like this, make sure you know what you're doing. Consult a professional if you need to. I scored a couple of DC to AC converters on the Web. Click to embiggen The panel in the back of the console pops right out with a screwdriver. Other panels of the console are removable as well. I sheathed the power cable in a red split loom, just because I had it left over from a previous project, and I thought that might protect it from any shifting or rubbing caused by the handbrake or moving the cable around. Next, I snaked the cable through the console and brought it up to the front where it could plug into the cigarette lighter. Therefore, it was splicing time! I also figured out that I was going to have to drill some sort of hole in the bottom of the cup holder for the wire to come through.
