Do you have to fill gearbox with seperate oil to the engine oil and how on a mitsubishi carisma manual
My friend and i are making a compressed air engine strong enough to work lawnmowers or better yet, a small car. Does anybody know any equations for calculating torque or RPM's? We are somewhat basing it off of the Airhogs air engine but better. Also, does anybody think making it out of PVC would be a good decision? or aluminum? I don't know if it will make lots of heat since there is no igniting of gases so i think it will be safe to use PVC for a lighter engine so more power can be used for moving. any thing wrong/bad about that?

What are the primary differences between the two? Which is a more rewarding career path? Which major is better for someone who wants to get a broad understanding of engineering? Is it feasible to get a double major?
Question by Chikpeas Brother | last reply
I am currently in the 2nd semester of my freshman year of college (University of Northern Iowa) as a physics major. This fall I am planning on transferring to Iowa State for computer engineering but I am starting to have second thoughts. I have always liked learning about technology and building projects (currently robots) and I can't imagine any major other than engineering. I got a C in calculus 1 and physics 1 and am currently taking physics 2 and calculus 2. Physics 2 should be fun (finally get to electricity and circuits) but I am worried about calc 2. I've never been a math genius; does this mean I'm in the wrong major? I guess I am looking for some advice on if I'm in the right major.

Amazingly enough, this recreation of one of the Concorde's engines was done with plans bought for 6 pounds, loads of styrofoam and paper, and an immense amount of time. Pretty amazing stuff that it seems anyone could do with plans... and foam... and scads of time. Yow. DIY Concorde

Alrighty so i saw an instructable here about cooking on a car engine bay, also a book called Manifold Destiny, and i was wondering what else can i cook. Do you think i can cook rolls of cookie dough, wrap it in tin foil and let it cook by the exhaust manifold? Sorta like bread, kinda sounds good right? Another thing, do you guys have any other food ideas (no matter how crazy it may seem) for cooking? (Im gonna go on a road trip in a few months and i wanted to do some research before i go.)

31.25 percent efficiency rate topples 1984 recordALBUQUERQUE, N.M. --On a perfect New Mexico winter day -- with the sky almost 10 percent brighter than usual -- Sandia National Laboratories and Stirling Energy Systems (SES) set a new solar-to-grid system conversion efficiency record by achieving a 31.25 percent net efficiency rate. The old 1984 record of 29.4 percent was toppled Jan. 31 on SES's "Serial #3" solar dish Stirling system at Sandia's National Solar Thermal Test Facility.The conversion efficiency is calculated by measuring the net energy delivered to the grid and dividing it by the solar energy hitting the dish mirrors. Auxiliary loads, such as water pumps, computers and tracking motors, are accounted for in the net power measurement."Gaining two whole points of conversion efficiency in this type of system is phenomenal," says Bruce Osborn, SES president and CEO. "This is a significant advancement that takes our dish engine systems well beyond the capacities of any other solar dish collectors and one step closer to commercializing an affordable system."Serial #3 was erected in May 2005 as part of a prototype six-dish model power plant at the Solar Thermal Test Facility that produces up to 150 kilowatts (kW) of grid-ready electrical power during the day. Each dish unit consists of 82 mirrors formed in a dish shape to focus the light to an intense beam.The solar dish generates electricity by focusing the sun's rays onto a receiver, which transmits the heat energy to a Stirling engine. The engine is a sealed system filled with hydrogen. As the gas heats and cools, its pressure rises and falls. The change in pressure drives the pistons inside the engine, producing mechanical power, which in turn drives a generator and makes electricity.More here:http://www.sandia.gov/news/resources/releases/2008/solargrid.html

Hey everybody! I'm just getting involved with the wonderful BEAM bots. The problem is that here in Germany I don't get some of the transistors and I have to find alternatives. Instead of the 2N3904 I use the BC546, for the 2N3906 I use the BC556 and for the MN1381 I use the TC-54. I'm attaching the datasheets - did I get it right that I only have to "turn the BC556 around" so the pins fit? However, I don't get the Miller engine working! As a solar cell I use a Panasonic BP-376634 (3,4V - 30mA) http://shop.aaaa-electronic.de/epages/15164820.sf/de_DE/?ObjectPath=/Shops/15164820/Products/50007-002 As capacitors I used different ones. The motor is a tiny cell-phone vibrating motor - I guess one of the tiniest. As a resistor I'm using a 2.2K. All in all I tried to follow these diagrams: http://www.solarbotics.net/library/circuits/se_t1_1381.html I also uploaded some photos - maybe you can make out mistakes I made... Hoping for your help! Sebastian

With present gas/pollution concerns and green tech merging with cars left and right... Why hasn't the steam engine been reborn? I mean what takes MORE power, Electricity to move a 1000lb car or heat up a heating element to heat water and make steam? With tanks strong enough to hold Hydrogen for cars why cant the same tech be used for a steam engine? All the fuel you would need would be water (solar panels/batteries to power heating) but just water for fuel. Thoughts?

I'm about to finish highschool, and hopefully head off to uni However, I still am a little unsure on my career path, which I think I need to be to choose a course for uni Originally, I wanted to become a mechatronic engineer, and I was hoping that by the time I got out, it would not be so new and unfamiliar an occupation. However, I dunno if that is gonna happen.... So instead, now I'm thinking about whether I should try to become an electronic engineer for something like a section of the Australian Defence Force... I'm just looking for a path that will later on help me get a stable job, with enough money to live comfortably (i.e get a house/car). I don't really want to waste my time on a degree that will not be worth the work put in, however. What do you think?

In Theory, A Stirling engine works on a difference of temperature. For many rural homes there is great expense in developing and sustaining power lines. These homes are already heating from an inside source, and create a difference of temperature, depending on the proximity to the firebox of at least 2X. If developed as a mobile stove, you could glean a mobile power source only dependant on supplying a small chamber with fuel. Such an engine would be able to sustain on green fuels as well if heating an area wasn't a factor. It might even pay for itself in an AC situation where the thermal difference is reversed. Why haven't we put a power source in every appartment using electric fuel?

*Hopefully this is the correct category..... Hello all! I am quite interested to start learning woodworking (already have some knowledge) And what better way to start that with a gas (or electric) go-kart :-P? I know fair amount of people who have built things out of wood, some younger than I am (14). And it seems like a very good skill to have. Plus, if I am good enough at it and I outgrow the go kart, Ca-CHING! I could sell it for profit (If it is in good enough condition still). I'm currently in 8th grade but I cannot take a woodworking class until 10th grade, So why not start? I was also wondering if the Ibles community could help? I could use some ideas, and I will need alot of info for the engine and frame.(If you can even find PEDAL CART info that would be awesome too). My plan is to have it done by mid summer (July 10 for me). This may seem like too much for me, but I want to build one that, if it doesn't have an engine, one could easily add one (I realize I can not run a gas/lawnmower engine on its side) Please leave your thoughts below!!

I know about adding a larger muffler but I do not want to reduce the engines power by restricting the flow and that is only half the noise issue, the other half is the mechanical noise from the engine.. I have seen the sound deadening generator enclosures / shelters for them to run in but they coast 800 and up. I cannot find any plans to build one myself . Anyone know where I can find plans for one or have other suggestions?

Hey guys. I'm in my final year of school before we all part ways and go to university, and a small group of us had an idea to do an outreach program to local primary schools- British equivalent of Elementary School with grade 7. As part of the program we are aiming to interest these kids in learning sciences and engineering since we could be doing with more people taking these subjects in the academy. So can you guys offer any suggestions as to what we can demonstrate and what activities we can get the kids involved in? We have a few ideas for biology, chemistry and physics but not so many for engineering... Just a little side note, I'm not sure how American schools operate but in Britain we have EXTENSIVE (annoying) health and safety crap and risk assessments if a pupil coughs, so nothing too... Explosive Thanks, Tom

This sounds like fun:A new Discovery Channel show is looking for teams of ARTISTS, SCIENTISTS, ENGINEERS, ARCHITECTS and DESIGNERS with experience in building RUBE GOLDBERG MACHINES. (Thanks to BoingBoing for the link!)More details:This show shoots in January in Los Angeles so the application process will be moving quickly.Super Rubes is a weekly one-hour show that follows a band of talented creators as they design, build, and set off a massive Chain Reaction Machine in front of a cheering crowd. The point of a Chain Reaction Machine is to do something very simple, like turn on a light bulb, using as many steps as possible. This is an opportunity for engineers to let their creative hair down and have some fun building a giant Chain Reaction Machine. Our team will take on impossible challenges (i.e. , Can you crack an egg with a human hair?) in a race against the clock.We are looking for fun, interesting, charismatic and outgoing individuals of all ethnicities and types 25-39 years old to comprise a diverse team of people who are involved in engineering/building: This means architects, engineers, scientists, pyro-technicians, art directors/designers, even professors or hobbyists who are simply passionate about these topics. We don't need an expert in every area, just someone who loves to design and build.The team should be a mix of a skills, a mix of personality types, and have a playful, funny camaraderie, so if there are existing teams out there, all the better, or if couples/triples have worked together and want to present themselves as the start of a team, we are open to that too.

If anybody likes automata, but can't be bothered to work in wood and metal, try Flying Pig models.They (mainly he) make and sell cardboard kits that move in interesting ways.Obviously, most of them are for sale, but he has some free models for downloading, which change very occasionally.Probably the most interesting parts of Flying Pig for this site, though, are his Workshop Notes blog, where Rob updates readers on the process he goes through developing his models (he's part way through a dinosaur at the moment, and has released a kids range).He also has a section of mechanisms, with animations of all the paper mechanisms he uses, plus several that don't go into paper models (like a stirling engine).Generally, it's a great resource for anybody interested in engineering, paper or otherwise.
