Small Scale Scuba Gear within $100?

I had an idea for a good instructable. I'm trying to plan out on paper a neat breathing apparatus for a hundred dollars. Constraints are that it has to fit on the face, can be carried anywhere, and should at least provide one minute of oxygen. As a plus, why not add a pump so you can replenish the air supply when its running low. The way i might build this, ultimately, shouldn't be too hard. But what is being difficult is what to use to hold the air supply. would an air tank from an airsoft gun be any good? or would i have to use something different to contain the pressure? Any input would be greatly appreciated! -Jakit

100% of Electricity from Renewable and Non-Carbon Sources in 10 Years

In the best talk of the 2008 Web 2.0 Summit Al Gore called for president-elect Obama to make a man-on-the-moon-like pledge to generate 100% of the United States' electricity from renewable and non-carbon sources within 10 years. Al Gore is truly an amazing orator, and when he got fired up about the climate, renewable energy, energy independence, and how it could play a centerpiece of our economy, I got fired up and so did the rest of the audience. What really sent shivers down my spine was this observation: When Neil Armstrong first stepped on the moon, the average age of the control engineers running the mission from Houston was 26, making them 18 when Kennedy made his pledge in 1960.Generating 100% of our electricity from renewables and non-carbon sources in 10 years (let's call it 100-in-10) is the same caliber of challenge, but unlike getting to the moon -- which was something only a government could do at the time -- building a full economy of renewable energy should be orchestrated by the government, but requires the efforts of countless makers. I seem huge numbers of opportunities, both large and small, to make a difference and have impact. Get an engineering degree and invent a new type of powerplant, design and publish plans for low-cost DIY solar home heaters, be an advocate of renewable products and services. It's clear that a lot can happen in 10 years, and even if Obama doesn't call for 100-in-10, the time to make a difference is now. This is cross-posted on Makezine here.

Just one to go... (Update...Just!)

A few people have taken the time to mention that I am approaching my century - almost 100 Instructables. OK, so plenty of people have gotten there before me, but this is my first hundred on the horizon. I have now published #99, and I know what #100 will be. Looking ahead, though, what will your hundredth project be? UPDATE: #100 nearly didn't happen, as I came off the road on the way to the site.  Fortunately, the people I was going to meet came to meet me part way and helped pull the Mini out of the field.  The Mini is now awaiting diagnosis at the garage, which will certainly involve the words "bent" and "steering". Anyhoo, I got what I needed, now just putting together some more research notes with the photos, then get it checked by an expert... UPDATE TO THE ORIGINAL UPDATE: #100 is, effectively, done.  I'm just waiting for the expert who helped me to give it a once-over to check I've got my facts straight.  Since I've been using her work email address, I expect to here sometime Monday... UPDATED UPDATE: Ow!  My shoulders, neck and back are ceasing up, typing is getting painful (something to do with dropping three feet at fifty and coming to a dead stop in the field...). But, the garage where I dropped Womble off has just phoned to say they can't find anything obviously wrong (or bent) with the car that would explain why the front wheels are pointing in different directions.  They theorise that the impact bounced things a notch or three along without actually damaging anything. But, they also recommend taking it to a specialist bodyshop to get it checked... PROBABLY-FINAL UPDATE: And now I have Womble back - all that was needed, after all that fuss, was a slight adjustment of the tracking.  Now that is engineering. ON-TOPIC UPDATE: #99 is now finished off with photos of the piñata in action.

Arduino relay power over Ethernet cable?

Hi. I have an Arduino setup with 2 individual relay boards controlling two 240v power outlets. The relays are housed separately from the Arduino and I have connected the two via a standard ethernet cable. The relays I have are both 12v powered and switched via a 5v Arduino digital pin. I have currently wired the following. Orange and orange/white ---> 12v+ (from a 12v plug transformer) Blue and blue/white ---> GROUND (connected to both plug transformer and Arduino GROUND) Brown ---> Switched +5v from Arduino to relay 1. Brown/white ---> Switched +5v from Arduino to relay 2. SITUATION. One of these relays for some reason isn't working properly. The board is receiving the right power but the relay itself is not clicking/switching. Maybe sticky contacts. The whole thing is already wired and the unused cables of the network cable trimmed so I cannot use them.  MY QUESTION I have a spare single 5v powered relay board which I could replace the faulty 12v with, but with no wires left to connect it, could I pinch one from the orange pair that I am sending 12v through to the first relay and use that for the 5v to the replacement one? In a less round about summary... can I send 12v+ through a single strand of ethernet cable with a run of only about 30cm? Thanks, Steve.

Remove corrosion from camera without complete disassembly? Answered

I recently got sunscreen sprayed in my camera, and now I believe the shutter button might have developed a short, which locks the camera up. Upon disassembly, I can remove the portion of the camera with selector/zoom/shutter dials, but not further disassembly can be made without some major work. Is there a way I can remove any corrosion buildup in this part without damaging it? It is not connected to any power source, so liquids are fine, but it does contain an array of plastic and metal parts, as well as ribbon cables.

Remove sunscreen from camera? Answered

Well, while on a camping trip last week, I accidentally happened to close my bag on a bottle of spray sunscreen that happened to be unlocked, which then happened to spray onto, and into, my panasonic FZ-100 camera. After attempting to clean, and a bit of time in rice, everything worked perfectly, albeit a bit sticky, until I had used it for about an hour. I believe one of the buttons/zoom levers has developed a short, keeping the camera pretty much locked up. Is there a way I can remove the sunscreen completely from the damaged parts? I got home and have taken the back casing off, and have access to all controls.

What size lens should I get for my projector?

I found the following video: https://www.youtube.com/watch?v=JdJ1gZDb6gM And I want to make a $100 1280x800 projector. In the comment section in that video he says he used a 120mm fresnel lens for the back (Focusing the 100W LED to the 5.6" LCD) and a 220mm fresnel lens for the front (Focusing the LCD to the wall). I want to make sure that I get the right lens.  Here is the site I am probably going to buy from: http://www.bhlens.com/fresnel_lens.aspx I might even post an article that links to their site so I can get the lens for free. Lastly, I'd like to say that I want it to as small as possible (Hence the reason for getting a not-so-common 5.6" LCD instead of a common 7"). Please help me choose a lens that will allow for the smallest possible space between the LCD, lenses, and light. I will make an Instructable for this later on.

A way to step up 30uV-300uV to 1mV+?

So I'm working at a TV repair shop but really we fix and work on almost anything electronic. In this situation we have a NEUROSIGN 100 which is used to tell the surgeon when he's near the nerve, but he needs the voltage spike to be recorded on paper when he touches the nerve. The problem is that the machine only gives out around 30uV-300uV as he is working and the electronic ghraph we have only startes recording at 1mV. We need a way to step up that voltage coming out the machine so that ghraph will record it. We tried a small audio amplifier but that didn't work at all so we're back to the drawing board.
