120V LED Under Cabinet Lighting

Hello everyone. I recently purchased a new home, of which has some nice Under cabinet lighting. But they are extremely hot when I use them. Heat = wasted energy right? I want to be as Green as possible in my new home. The problem is, the Bulbs are these weird straight 120V Bulbs from Westek., the question is, Can I some how make an LED replacement Bulb? Each housing has 2 of these bulbs, and I have 4 of the housings. I can't read schematics, but any info would rock. Thanks everyone.

Creaking under the Strain?

I've been getting periods of 503 errors (service unavailable) from Instructables recently. Are the servers creaking under the strain of all these weighty PRO members, or is the Instructables Robot hard at it mucking out the caches as he tweaks the privileges?

Dead Lawn--Fix Ph under evergreen trees.

Coniferous trees (pines, etc) acidify soil under em. Lawn doesn't cope wit this too well. Dump your old boxes of baking soda from freezer/fridge under pine tree. It works. Grass grows better. I'd do an -ible, but didn't bother to take pics. If you try it, maybe take before + after pics and post an -ible.

Why is my list of Groups under "Settings"? Shouldn't it be in "Discussions"?

I just spent an unproductive five minutes trying to track down the list of groups which I have joined. It used to be on the consolidated "main page" of .../you/. Now it turns out to be tacked on as an afterthought as the very last sub-category link under Settings. Why? Doesn't it belong under Discussions, along with Forums, Questions, etc.?

Cheap Under Deck Ceiling - Looking for details, anyone done this?

I'm 'fixing to get ready' to build this under my deck  to cover a 16' wide x 12' long space under my deck.  It looks simple enough, and there are a couple of YouTube videos of the same thing, but they all leave out some detail.Has anyone here done one of these? I think it needs flashing at the house end so water isn't weeping down the siding. Any other tips or tricks you found ? Thank you. ! Terry, Council Bluffs, Iowa

'Leather' channel under 'Workshop'?

I believe a 'Leather' channel under the 'Workshop' category would be a good idea. I say this, because I'm often looking for leather-related instructables, and I suspect that many other people are, too. Leatherworking is as much its own specialized skill as sewing, woodworking, electronics, etc. Maybe you could even inaugurate the grand opening with a contest. :)

How to store hydrogen under pressure

I've made several hydrogen generators via electrolysis, but every time I failed to store the generated hydrogen under (some) pressure. In this-> video they used an emptied fire extinguiser to store the hydrogen. The only problem with this is that they use a chemical reaction to generate the hydrogen whereas I want to use a renewable source (electricity).  I have a compressor so I could use that to generate the pressure. Has anyone got any ideas on how I could store hydrogen under pressure? Thanks

K'nex Projects: Always under the K'nex Category or Not

Have you ever made an I'ble of something made out of K'nex, but it is something which could go under another category of posts, such as a piece of furniture or organization item? I've seen some chairs/stools made from K'nex and I myself have recently made a bookstand out of K'nex. Where do you think such posts should be put? Is K'nex always going to go under K'nex? Or does what it is as a whole which decides where it should go? Currently you can only choose one category when publishing. So what is your opinion on this issue?

Questions tab under discussions shows I have no answers on page 2++

On my 'me' page, under answers, it shows I have 2 questions, and 38 answers. If I use the 'next page' button to show the next 10 'answers' I've given, that page, and all subsequent pages show I have no questions. Hypothesis: (the same offset of +10 is being applied to both the questions and answers, and seeing there are no questions 10+ it shows none)

I have noticed that on Instructables, I seldom see anything relating to computer programming. I'd like to change that. I would strongly reccomend adding a tab labled: Programing under the Tech section of instructables. To clarify this, I am referring to the sections under Tech. e.g. CNC and Microsoft.  Thank you.

Making UV paint.- How to

Hi, I need some UV paint that is inviable under normal light that turns bright white under blacklights. I will painting it on a giant hanging sign. I need a recipe for some uv paint or a cheap source of it. It looks like it cost around $70 dollars for 1 gallon and I need around 3 gallons of it. I know that you can use tonic water but I don't have experience using it (How bright will it glow). Also you can use laundry detergent but I dont know if it will show in normal. The key is it to not glow the under normal light and for it glow brightly under uv light, and it needs to be cheap. Any one have any experience with uv lights, paints, or other related things. Any comments are welcome. Thanks for your time. Joe R

New Category: Origami

Origami needs its own category. Seriously.  Yes, there is a 'paper' category under living and yes, there is a 'paper airplanes' category under play but origami deserves its own home. Even though I've posted a lot of origami in the paper category, I always feel weird doing it since I feel like Living, Paper is for stuff like making paper, books, cards, and maybe paper craft (though this should be under the play category and maybe have a section of its own too). I've also posted a few things in the paper airplane's category because it's flying origami but still don't feel like it's the right place for it. I feel like origami much better fits under the Play area (instead of living) and there is definitely enough of it to warrant its own category. Please give the orphan origami a home.
