A "Thank you" to an anonymous doner...

Someone gave me a free pro membership.  Since I do not know who it was and thus cannot thank them personally on their orangeboards/PM's, I have decided to post this topic to publicly thank the person who gave it to me.  To whoever gave it to me, you know who you are, thanks a bunch.  And the timing couldn't have been better, my birthday is coming up soon lol.

Plant Electricity Generator?!

OK. this is gonna sound very crazy. i remember learning this thing about photosynthesis. there are electron acceptors and donors. during photosynthesis, the electrons are passed on and on. it's like redox reaction. or perhaps it is redox reaction. anyway i came up with a crazy idea of generating electricity from plants. there just might not be enough electrons to do the "work" (to get at least 5V? impossible.). batteries have the + and - terminal. plants have electron acceptors and donors. crazy, eh? what do y'all think?

Another thank you to an anonymous donor

Like DJ Radio, someone has given me a Pro membership, and I'd like to thank them. I feel a little guilty about this, actually...I've been putting off buying one myself until I had college paid for and could warrant frivolities like website memberships, and I just made National Merit Finalist, which means I get a full-ride... Point is, thank you to whoever is behind this. I am quite grateful, though a bit annoyed that now I feel obligated to build and post something...something relatively major is in the works, though. ;-)

Recumbent cycle: "blue sky" design query

I am not one of nature's cyclists. I didn't actually learn properly until I was in my twenties. My bike is very old, very rusty and very, very heavy.However, I feel that I "ought" to cycle more, for shopping trips and the like. I quite like the idea of switching to a recumbent, but they are expensive (current available funds: zero).So, I'm playing with the idea of rebuilding my mountain bike into a recumbent (and learning how to weld on the fly?).In the sketch below;The black section is the back of the old bike, turned upside down.The blue section is the front of the donor bike.The red part would need fabricating somehow.I haven't thought properly about steering mechanisms, but probably under the seat, via cables to arms welded to the forks of the will-be-the-back wheel.Would the bike, as I have sketched it, in principle, work?I'm bothered about stability, especially at take-off and landing. Am I worrying unnecessarily? I have access to a second donor cycle. Is there any mileage thinking about "doubling up" the blue section, to make a trike? Not massively wide, but I could add luggage space, or an extra rear-facing chair-style seat.Brakes: before I cut up the bikes, am I right in thinking that I just remove the cables and levers from the handle-bars and add them to the under-seat steering?Gears: the donor bike is a mountain bike, but I never used all the gears anyway. This area is pretty flat - can I get away without any gears?Coasting: although the back of the donor bike ends up upside-down, it is still turning the same way, so I can still coast OK.I'm sure I've missed something obvious...Anyway, even though I've not decided to do this for certain, I'd appreciate any comments or thoughts.

Steampunk Taxidermy - time-travelling rodents.

Chuffy and his Time Machine, Chuffy (mouse) sits in the little carriage on top of the Time Machine (guinea pig). He is having some mechanical problems getting it started, so the hatch on the side of the Guinea pig is open to reveal vintage clockwork cogs that make the Time Machine work, when it hasn't broken down anyway! Apparently, the donor animals are all natural deaths, including gifts from the maker's cat.

"Organ donors"... or: sources for tube project parts...

The "Vacuum Tube" group needs a first forum topic. Here it is... Sorry 'bout the pun... but I could have used Time to get Organized... Be thankful ;-)Vacuum tubes and parts tend to be rather expensive these days. But there's a good source for parts, and it's often free: old tube organs.I picked up a working 1960 Wurlitzer a couple days ago. It's got:-- full complement of tubes (the mother lode!), including9 (nine!) 12AX7 preamp tubes.2 6L6-GC power tubes1 5U4-GB rectifier(there were other tubes: (28!) 12fq8's but they're not so useful for audio...)-- Huge power transformer-- Large (20-25 watt) output tranformer-- two 16 ohm speakers-- lots of carbon-comp resistors, sockets and other reusables.Total cost--just gas, and a sore back.Even the non-tube organs are a good source of speakers, reverb tanks, pedals, etc. The tank, bass pedals and the volume pedal were from a solid-state Conn organ left on the curb...The bass pedals could be made into a MIDI project, and the volume pedal would be a nice start of a wah, or left as-is. Yeah, they are grungy, but that's easy to fix....

Donate Your RV

Hello Guys, Donating a recreational vehicle to charity helps an organization and can result in a tax benefit for you, the donor. The Internal Revenue Service allows taxpayers a deduction for donating vehicles, including RVs, to certain charities. Special rules, however, apply to these donations and can affect the amount of your deduction. Find a charity that is qualified to receive tax-deductible donations and that accepts RV donations. Many charities, including churches, youth clubs and homeless shelters, seek vehicle donations, either for their own use or for resale. Thanks a lot! Tim Boon http://www.carsforprostatecancer.org/

Would you like your own satellite? (Contest with $1500 prize)

Oh the joy of Twitter!  I just found out about this very cool contest from Discover Magazine via BoingBoing: Imagine having your own personal satellite orbiting the Earth. It’s got cameras and sensors galore, and you can use it to run experiments, take pictures, and even beam messages back to the blue marble. Well, that geek fantasy will become a reality if the ArduSat project, which you can see here on Kickstarter, reaches its funding goal. The general public will be able to rent time on this small satellite and use it for whatever they please, courtesy of its Arduino processor. [The folks] at Discover Magazine think this is pretty neat. And [they'd] like to give away a development kit worth $1500 to the Kickstarter donor who submits the best idea for an in-space experiment before July 15th, 2012. The kit includes Arduinos and an advanced sensor suite shipped to your home address, as well as one week of up-time on the satellite to run any experiment. You’ll be able to build the experiment yourself and have it be sent up on ArduSat when it takes to the skies. Here’s what you have to do to enter the (drumroll) Discover Space Challenge: (1) Fund the ArduSat project, for however much or little as you desire. You’ll receive a personal code that identifies you as a donor. (2) Read the contest guidelines here to learn about how you should design and submit your idea. (3) Enter with this entry form, making sure to include your personal code. (4) Wait for winners to be announced on July 20th, after judging by Discover blogger Phil Plait, Discover Editor-in-Chief Corey Powell, and an expert panel of judges. (5) Rejoice!

Twins Separated At Birth Met And Married

Http://news.yahoo.com/s/nm/20080111/od_nm/twins_odd_dc;_ylt=AoZvBFiQ44VpuITp2zqX9sWs0NUEI know it's not really what iBles is about... but I couldn't resist posting it.Here is the article from Yahoo! News:Fri Jan 11, 2:33 PM ETA couple discovered after they had married that they were twins who had been split up at birth and adopted by separate families, according to a member of Britain's House of Lords.British peer David Alton recounted the story to parliament last month to support his argument that artificially conceived children should be told who their biological parents are.Alton said he had heard the story of the separated twins from a High Court judge who had dealt with the case."This did not involve in vitro fertilization: It involved the normal birth of twins who were separated at birth and adopted by separate parents," said Alton, an independent member of the Lords. "They were never told that they were twins.""They met later in life and felt an inevitable attraction, and the judge had to deal with the consequences of the marriage that they entered into and all the issues of their separation," he said."I suspect that it will be a matter of litigation in the future if we do not make information of this kind available to children who have been donor-conceived," he said.Alton could not immediately be reached for comment and no further information was available about the twins or where they were from."I think it's a very tragic story for the people involved," said Pam Hodgkins, head of a group that helps adults affected by adoption."It is a lesson that we need to learn and apply to the situation of donor-conceived children," she told Sky News."Whilst ... nowadays it would be most unusual for siblings to be separated ... the risk of secrecy affecting the lives of people born as a result of egg and sperm donation is exactly the same as the risks that have affected adopted people in the past," she said.

A Letter to my Instructables Family

Dear instructables family, I come to you today to ask for your loving support because the Positive "sunshine" you know here, is hurting for my sister, her son and my family. It takes a huge blow to knock me down to the point that I am discouraged but the past few months my family has endured tragedies that have been difficult to bare and to openly share. My nephew has needed a kidney and pancreas transplant for five years and has recently been accepted into the donor transplant program and one of the requirements is to set up a funding program to cover medical expenses that are not covered by his insurance. Although we do not have a huge family and friend support group, we have managed to raise 65% of the modest $5000.00 that is needed for his transplant. We are nearing the end of our fundraiser and although it is very difficult for me to ask for help. I am humbled at this point and ask for your loving support. We have always been a hard working self sufficient family and have never had to ask for help from people outside our immediate family until now . . . Your support would bring a great relief to my sister who is 75 years old and about to collapse under the pressure of all the responsibilities of taking care of her youngest child who is 50. We are grateful for your consideration and support ~ I love my dear instructables family and all of the love you have shown me over the years. sunshiine~ https://pages.giveforward.com/medical/page-z85hhz/?utm_swu=2297#activity-feed-wrapper

Induction heater 2.0

Some might have already tried my first induction heater, which was more a proof of concept than a modern device. Although I like to keep things simple where possible I want to upgrade my heater to a fully electronic version running on mains power. This time the base concept is to use a cheap induction cooktop for the control and power source. After using a few already as a communication device I realised it is a costly way of producing smoke signs but I am getting on the right track with the design now. So my obvious questions are: 1. Did actually anyone ever built my current induction heater and if so, can you provide some nice pics? 2. If you were interested in a hobby induction heater, what would like to do with it?     E.g: Just for curiosity on how it works, heat treatment of punches, chisels and similar,     heat treating knifes or even swords, sheet metal work.... 3. What would like to have included?     E.g: Water cooling for continous use, air cooling (mostly for smaller and quick jobs), exchangable coils,     additional micro controller for temp, water and remote control (foot panel or similar)... 4. Do you require a fully shielded version to avoid interference? 5. If you are based in AU (preferable VIC): Would you be able to donate me faulty (partially or fully) or working induction cooktops,     for example discarded units with broken glass tops?     Would you able to donate me copper tubing OD8mm or less? Leftovers from pluming installations, old LPS systems or similar?     Prefered lenght 1m or longer as the coils need quite a few turns... :(     Each donor will of course be listed in the Instructable unless you prefer to remain unnamed. Let me know what you think because this time I am not just building for myself, this time it is for you!
