Birds and sticky flytraps HELP!!! NOW!!!

Just now, my bird flew into a flytrap, i got him out of it, got bit numerous times by a stressed bird, HURT LIKE HELL! and now he's sticky, i need to know how to get the stickiness off of him, i used olive oil on his beak to get the stickiness off of that, his head feathers didn't get trapped (thank goodness) but i need to know how to clean him without having to touch under his wings, he doesn't like that. i don't think it got past his down to his skin. He is also sneezing more than usual are sticky flytraps poisonous? there isn't any facts on the package, google wasn't much help either. I AM NOT SPRAYING WD-40 ON MY BIRD. Please help.

Timer activated liquid dispenser.

I am looking for an alternative to the alcohol dispenser I saw on your site.I am looking to make a dispenser that can handle being used all day long filling 2 oz bottles with a fine light oil. Your alcohol dispenser is close but seemed rather light weight. I would also prefer to use some sort of inexpensive timer rather than the proximity sensor used in your presentation.I am wondering if you could furnish me with a list of materials, where to get them, and a wiring diagram. This filler will be used to help support a mission project for an orphanage of children that lost parents to HIV AIDS.As an architect, I was able to design and donate blueprints and supervision for a children's home and chapel at this mission but a little device to fill these bottles has me stumped. I am now 83 years old and don't have access any more to all of the engineering help that I once had, nor do I have the finances anymore to purchase the high-end units that are available. We are trying our best to raise money, not to spend it.katabwa

Bad stereo ground/fried alternator

After reading the instructions I installed an aftermarket stereo in my 1999 Toyota Camry. I'm confident in that I made all the proper connections correctly, but I think my ground wire is bad.a few day after I heard a high pitch whine that got louder when the rpms got higher. Then the power would cut off from the stereo but only for a split second, then my car would do the same thing until ultumitly it was completely DEAD I couldn't even turn on my hazards. I'm pretty sure my alternator is fried. And I think it's the ground wire. Now my question is can I run a direct ground from my stereo to the car or do I have to chase this wire down?

How can I make a USB to 56k Modem or Ethernet to 56k/fax Modem?

I'm trying to reconnect my Sega Dreamcast to the internet, the trouble is that it only has a 56k phone-line modem. How can I "slow down" my internet for it, without spending $30 on a store-bought (http://www.usr.com/products/modem/modem-product.asp?sku=USR5637) or editing my computer's registry and using its internal pci modem.

Thanks in advance. :) Edit: As far as I know, Dreamcast communicates like a PC does on dial up - though sometimes there's not enough voltage through the line. Could a spare dsl modem be reversed, providing a dail tone and 56k? This is a better option for me than all the other methods mentioned because its automated and more like using actual dial-up.

Non-toxic, natural, cheap and WATER-PROOF adhesive or glue, is this impossible?

I'm a quality engineer working for a company in Turkey, the company collects the coaldust ( powder form of the coal )  from all the cities of Turkey and makes them briquettes by pressing with very powerful machines. Of course we use some adhesives for mechanical strength of the briquettes. We use CMC (a kind of cellulose) and this material is soluable in water. So our briquettes are not very durable under rain or moisture. Now I have to change the binder or adhesive materials in order to produce waterproof briquettes. I dont know how it's possible. I have to use nontoxic natural materials, and cheap as well. Last week I tried to do something but we were unlucky maybe. I tried to use Technical Gelatin and Alum (Al. Sulphate ) together, the briquettes seemed very good after production but they were not durable when I left them in a cup of water. So I have to find a solution now. Can you help me about that? I'd be very pleased. Thanks.

Video Game Ideas Wanted

A couple of friends and I are planning on making our own Video Game. I thought it would be cool to ask others for ideas. Our game is a mixed genre (we are attempting to put as many game types into one as possible, but still keeping it somewhat reasonable) sci fi game based a couple hundred years into the future. Humans have colonized mars, but their is a war between the two planetary alliances. Meanwhile there is an underground organization that controls everything going on in human society. They prepare for the return of the true martian race who left behind some ancient relics which were discovered and kept a secret. The main character is a super soldier created by the underground society. You unite the human race and fight against the aliens. We have story ideas but would like to hear ideas from other people. All suggestions are welcome. Suggestions could include, but are not limited to: Characters Events Weapons Technology Genre types Plot ideas and twists Side missions One other thing is that we were thinking that the aliens could be human based, and be like a sub-species of humans. Yes or No? Any other ideas are welcome. Thanks to all who help.

Electronic repair after a voltage spike or power surge

So far I was lucky and never got a lightning strike or other power failure to induce high voltages into my house and equippment. But over the time I got several requests from friends to take a look at things after literally all connected electronics in their house got fried. In some cases there is only a total write off as due to a lack of surge protectors inside all unwanted juice made it's way into vital components. Like a brand new Samsung TV where the replacement of the power board was the only option - which makes you wonder... But in other cases, like microwaves, induction cooktops, computers and such I had some good success with the repairs. Guess it comes down to purs luck on both sides, power surge was not too bad and simple components on the input side failed quickly enough to prevent damage to microprocessors or other sensitive parts. Right now I have an induction cooktop here again that failed after a mains transformer in street blew up during a thunderstorm. I can tell it was bad as everything in the area of fried parts has a vaporizsed metal film on the surface and not much is left that was a surge protection. I cleaned all up, replaced the varistors and missing parts of the traces on the circuit board but the cooktop is not performing the way it should anymore :( At some stage during cooking it turns off with a meaningless error code stating the input voltage was out of bounds. So my next attempt was to literally remove every single component from the filter and power supply board to measure for any possible connections between the traces. By doing so I noticed several points where I had a quite high but measurable resistance in areas where there should be none. Mostly on the direct input side where the varistors tried to save things. So I used my Dremel in a tin drill press to cut the circuit board aourd the affect areas (where possible with a drill, otherwise with a thin grinding disk).. Sure enough I was greeted by charcoal colored dust in several areas. After removing all material until the dust was "clean"  tried again and this time all seems to work fine. I would like to use this topic to offer some help and guidance in case you have devices that suffered a severe power surge of some sort. Many of us either have no insurance to replace those items or even if you do the device might be expensive enough to try a repair despite getting it replaced. Trust me, even it went up in smoke there is still a chance to fix it in some cases and if proper protective circuits were in place the repair could as cheap as a few Dollars for replacement parts. To get useful advice the following things should be included in your request: Some clear pictures showing a close up of the affected parts - if there is visibale damage to be seen. A brief description of what happened, e.g.: lightning strike directly into the house or outside power lines, generator or inverter failure or simply that the power company stuffed up and your entire street was affected. Of course you will need the means to take the device apart for investigation and also some basic soldering skills or somehow how has and can assist you. But if you are up to the challange I am willing to help if possible.

Best motor suited for a diy generator that can provide 48V?

Ok, out of all places, I've seen this particular question be asked once and the discussion trailed off topic somewhere. Before we start, Yes it's a bit of a backwards thought but it's still a project, experiment and I'd do it for the sake of doing it. I have an electric scooter - lack of knowledge for proper battery care during winter lead it to 4 dead batteries. In my area, as long as the scooter is moved by an electric motor and makes less than 40km/h it's a street legal and non insurance or license requiring vehicle. Only issue for me is the limit of the battery capacitance and the eventual depreciation of the battery capacity. So I want to try an experiment of strapping a small weedwacker motor or even a hobby airplane fuel motor to an electric motor to act as a power source for the scooter. Don't laugh, It's an experiment. Yes, I'm aware I can just buy batteries. they are 50 bucks a battery + 12 bucks shipping and mine ran on 4x of these suckers. Buying batteries would work but would not satisfy the curiosity of an experiment.. Now then: ============================================== My scooter, when bought, could do about 12 blocks (1 block = 2km ) trip on a full charge. Before this winter, it could do 8 barely. It ran on 4x Lead Acid 12v 18Ah batteries. Now the batteries are connected in series so that's 4x 12v 18Ah making it 48v 18Ah. At this point we can drop the need to have the generator produce exactly 18Ah of current because that originally is the total battery capacitance, determining how long we can ride before draining of the batteries. So with a generator, all we need is to draw sufficient Current at the moment of generation. Which motors are best suited for generating 48v. I'm obviously missing some que variables here but I just want a point in the right direction. I'll most likely need extra head room and make a Step Down Buck Converter. Every time A talk of a diy generator comes up, people seem to mention Stepper motors. Seem like good choices? Brush-less, multi lead motors, yes - no?

If I were building a pottery wheel, what would be the ideal situation in terms of motor specifications? Answered

Would the motor from a belt-drive circular saw be sufficient? Is there a simple way to regulate speed reliably and safely? Thanks for your time!

How to magnetize new refrigerator door gasket????

Refrigerator door gasket came unmagnetized. Very expensive, and, royal frustration thus far. Got the thing installed okay, but there is no 'seal'. Supposedly, according to Whirlpool, they don't need magnets in the fridge door gaskets to seal.....(Yeah, right) Any way to make a gouzer? Figured I could depend on help here. If I had enough magnets, I'd make my own. Also, why are the gaskets on the door?

Soundproof Sleeping Closure

Hello fellow instructables :) Right I need some help and advice on a design brief to help fix my problem. Problem - I live in a ground floor flat and there is 1 flat above me, 2 scum bags occupy it, a couple of 22 year olds and they have obviously never been taught consideration for others and they bang and thrash around all through the early hours of the morning. When they bang on their bare wooden floor it sounds like a heavy metal dumbbell coming through my ceiling and it wakes me abruptly and its ruining my life :( I've complained to the council the past 18 months but there not interested. They have not put any carpet down in their flat in the last 18 months and it looks like they have no intention of doing so (they can afford fags n booze tho), plus they have a baby due any day now, great.. so now there making their problems, my problem. Solution - The only thing I can think of is making a soundproof sleeping closure, a large box like a 4 poster bed but all sides solid made out of a layer of MDF then insulation then more mdf, but I have some questions before I start. How would I get adequate air in and out ? Would this even stop the banging on my ceiling waking me up ? or would it still penetrate the box ? How would I control the temperature, would it be too hot in there ? Something like the image below but more solid with a door. If anyone has any experience with this or input or any good ideas I'd be ever so grateful. Cheers in advance. Matt
