Feedback for my website?

After a couple of months of building my website, it is finally in a state where I am proud of it! However the people using it are my friends, and I need some fresh eyes for feedback. Basically it's called Come Clean, and you make confessions to get them off your chest. Simple idea really. So please visit my website and tell me what you think: http://www.comeclean.co.nz       If you think something is good or bad, or if you spot a bug, leave a comment :) Thanks!

Homebuilt AC

Hello again everybody, bwpatton1 here with another one of his strange Ideas..... not as dangerous this time. Well, we built a gameroom, and currently it has a 10000 BTU window unit, in the South Texas summer it has a hard time keeping up, it also uses 900watts, well 900watts by itself isnt bad but we have two of these b/c we have two floors. I was wondering if i could build an AC to help supplement the run times of these AC's. My idea was to get an old refrigerator (and keep it outside) and run copper tubing through the freezer and into the refrigerator area and out of the refrigerator. Then, run this copper tube to a copper coil with a blower fan. Sound good sofar? Then I would run the end of the tubing back to the top of the freezer, somewhere in there there would be an inline pump somewhere............ OH and the lines would be filled with water/antifreeze??? Does anybody think this would be efficient enough to build? Or am I just wasting my/your time Diagram- the thing to the left is the refrigerator, and the squiggles are copper coils, and the thing to the right is a blower/coil. You were supposed to be able to read the writing on the diagram but the camera wouldnt cooperate

Railbiking. Anyone built one?

I heard an interview today with author William Least Heat-Moon.  In his latest book, he meets a man who has built an outrigger bicycle he calls a "Railcycle", which he uses to ride on disused railroad tracks all over the world. Curious, I did some searching, and found a number of places on the web where people are talking about this, but they all seem outdated. Bentley Railbikes Railbike Tours Homebuilt Railbike Has anyone else heard of this practice?  Do you know of anyone currently making and riding such contraptions?  Do you have one of your own?

solar powered cooler

Using these ideas as a starting point:http://en.wikipedia.org/wiki/Icy_Ballhttp://en.wikipedia.org/wiki/Einstein_refrigeratorhttp://en.wikipedia.org/wiki/Gas-absorption_refrigerator"Another variant uses air, water, and a salt solution. Warm air is passed through a sprayed solution of salt water. The spray absorbs humidity from the air. The air is then passed through an evaporative cooler. Humidity is removed from the cooled air with another spray of salt solution. The salt solution is regenerated by heating it under low pressure, causing water to evaporate. The water evaporated from the salt solution is recondensed, and rerouted back to the evaporative cooler."Directions on how to make an icy ball. URL works occasionally.http://crosleyautoclub.com/IcyBall/HomeBuilt/HallPlans/IB_Directions.htmlhttp://blog.modernmechanix.com/2007/07/19/refrigerator-uses-solar-energy/Is a non-flammable, non-toxic, and low pressure version possible?

Homemade hydro excavator?

I recently stumbled onto a website that sold a special hose and powerhead that allowed a typical pressure washer to be used as a sewer jetter (unclogging sewer lines).  I was blown away.  So simple.  Pure genius. Then it occurred to me:   A standard pressure washer could be used as part of homemade hydro excavator -- a digging tool that liquefies soil and removes it with a vacuum.  These machines can excavate around pipes without damage and make surgical-style incisions in the earth. Very precise. Very fast.  Factory made hydro excavators are *very* expensive and they typically rent for $350.00+ per day.   To turn a pressure washer into a hydro excavator, you'd need an economical homebuilt vacuum tank to suck up the liquefied soil and a vacuum hose attachment for the wand.  The excavated liquefied soil is very heavy -- so weight considerations and spoil removal are engineering issues to work on. So ..... anyone know how to build an economical vacuum tank?

need good battery options... help?

I've got a bit of a confusing circuit going on, and I need to figure out a good battery option. The battery pack must supply 9v@400ma to one connector (2x 2.4ghz video receivers in parallel with each needing 9v@200ma) and 6v@1.6a to the other (2x portable LCD TVs in parallel with each needing 6v@800ma).If my calculations are correct, I'd need a 9v battery that puts out 1.5a to support the whole kit & kabootle. I'd like a minimum of a 2hr run time, so we're talking 9v, 3000mah)I need it to be rechargeable, with the ability to run the system while charging from a dc adapter.Assumedly, I'd also need a DC/DC transformer from 9v to 6v with as little loss as possible.Can anyone point me in the right direction for batteries, chargers, and transformers? Either (relatively easy) homebuilt options or pre-made options are good.also, what are the pros and cons to each option (if you know)?any help would be greatly appreciated

RF Development Kit-Advanced, but could be a lot of fun

Micrel SemiconductorEbay{{{ I have noticed that some people are concerned that due to surface mount technology you can't make electronic stuff anymore. It is not true. A search will quickly find forums discussing how homebuilt electronics experimenters are getting around this. I have a nifty RF development kit for sale on ebay. See ebay link below. These development kits are used by new product developers to quickly get their RF prototypes up and running to develop software, hardware and firmware without the steep learning curve associated with starting development with discrete components. These boards allow you to build custom devices that can comunicate with each other up to a mile apart. Although this is not quite ham worthy distance someone might be able to have some fun with the kit. I have just one, but more (and the actual rf chip) could be acquired through Micrel Semiconductors. Anyway, I have this listed as an industrial item, so I am not sure the right people will see the ad. For those interested in playing with current technology RF.}}}

Recumbent Riders?

Just curious if anyone else here rides a 'bent. I've just been getting more and more excited as I continue looking for my own :) I'm currently in the market and have test rode a Bacchetta Strada, Volae (something or other), Rans Rocket and a no name unknown import SWB. I'm also waiting to hear back about a partially built M5 frame (think "sports car" class of 'bents). And don't forget my homebuilt abomination :D Today I rode a no name something or other found on Craigs List... In my home town too! It's not exactly what I'm looking for (it's too recreational for me), but almost exactly perfect for my father. It's got absolutely garbage components, but I see potential in it. It is, however, a dog on weight - ~40 pounds. But that's not an issue because there's no hills :D The seat is also a POS, so never mind the makeshift seat back made from bike inner tubes. <--- totally awesome by the way. But I think with a new seat, some cable management, better handlebar/stem and at the very least - new shifters -- it will be fun, reliable and a more road worthy 'bent. The price was right for this thing too :p Cheaper than an upright from walmart :D

Are you to blame?

OK, I know it's a deliberately attention-grabbing topic name. Sorry about that.There was a post on the Bamboo bike frame, essentially saying "a disclaimer that this could be dangerous isn't enough; people aren't qualified to judge the strength of their homebuilt bike frames so might still get hurt even if they are careful", which attracted a lot of ire, but also a response from whiteoakart reframing the question, thus:As a maker and writer of an Instructable, what is your responsibility to keep your readers safe? How far does your culpability extend?This is obviously a knotty issue, and one that seems to have a range of attitudes across the board- some people say "pointy things are pointy, hot things are burny, don't hurt yourself" and leave it at that, some people list all the grievous injuries possible from their Instructable.In my opinion, there are two major things to consider:Is a person likely to do themselves harm even taking reasonable precautions?An Instructable on how to weld, with clear advice on breathing protection, eye protection and not electrocuting yourself should be "safe"An Instructable on free rock climbing, even with all the advice in the world about how to climb well, could easily get someone killed because free climbing is inherently dangerousIs the intended audience capable of accurately assessing the risks? The risks of a table saw are obvious- put your hands in the wrong bit and it will cut them off- but the risks of high-voltage electrics are harder to judge with simple "common sense" because a seemingly minor fault could be lethal.Both of these have an element of "reasonable" to them- if you make your instructions foolproof nature will give you a bigger fool, but there is a point at which it is reasonable to assume that a sensible person following your instructions with care and attention will not injure themselves.More thoughts?

Ch. 1 In which SHIFT! comes to Instructables and is very excited to begin

Hey Instructabrarians, So here I am.  Headquarters of Instructables.  In 82cd Second St, San Francisco.   AND IT'S FREAKING AWESOME! Seriously, I still can't believe I get to come here every day!  While the outside may appear small, the entire facility is huge.  Immediately upon entering the building you are greeted by a long  ascending brick encased stairwell, which gives a very good impression of a classic London bookstore, which lead up to about a 15 foot high rise above the SF Streets.  Then, at the top of the stairs the whole building unfolds to reveal the entire HQ of Instructables, a place where you can instantly tell there's always something new going on.  It's quite filled with different projects, and various workshops that decorate the interim of the facility.  Exactly like an oversized engineering student's dorm room might look.   This place is amazing!  As soon as you enter you can immediately tell this is a place where DIY and homebrew are the norm.  Each room is actually organized like the Category section on their site- they've got a Kitchen for Food and Cooking, an awesome Workshop (complete with Laser Cutting Printer), Electronics and homebuilt ardruino Robot table, shelves filled with Arts and Crafts.   As a huge fan of the site I couldn't help but point out how many classic 'ibles I recognized.  Another awesome fact about instructables. While most companies would provide the usual simple shed or bike rack to employees, Instructables is smarter and more creative.  They hang their bikes on the wall. WOW.  I can say I never would've thought of that. Even their bathrooms are awesome- they decorated one of their doors with a Portal Cake sign! Honestly that alone is worth several points on the TV Tropes "So Cool It's Awesome" factor.    And I haven't even come CLOSE to describing the rest of the facility!   However, most important to me, is that the people are so friendly.  I was really worried about my first day job, but everyone was extremely nice and welcoming to me and I can't wait to begin work!   But the truly best part is that they're not just awesome Instructabrarian Employers, they themselves are also huge fans of the site and have their own personal instructables.  Tuesday is show and tell day where everyone presents something new they're working on and I can't wait to see it!  They're also completely understanding and are even giving me some time to work on my DIY PIXAR booth for the Maker Faire!   Thanks!  Anyway, today is Wednesday so not a ton of people are in today.  Luckily I got a chance to talk with Instructables gurus such as Sarah, Christy and Eric Wilhelm (yes, THE Eric Wilhelm!).  Right now a NBC new crew, or is it CBS?, is filming a special report on Fenix on their latest project- a portable power generator for the Middle East!  Overall, this is such an amazing introduction for me.  I'm still totally geeking out about all of this and I hope this dream doesn't end soon! -ME PS I'm sorry if I forgot to mention anyone.  Also, 3-DMO (my N3DS) pictures will be uploaded on my flickr site soon.
