Scrollbar text boxes

I have just started making a few Arduino Instructables and am wondering how I can put the scrollbar text boxes like at Step 15: Program of this Intructable I do not have Pro membership. Also is there any way to post formatted Arduino code within the Instructables. Hopefully someone might be able to help me with these questions, thanks Pedro.

Powdered Tempra Paint

I work in a child care with preschool aged children.  We just got a massive donation of powdered tempra paint. I was wondering if there was any interesting craft ideas that we could use other than 1. add water 2. paint with brush Other than using tempra powder to make sidewalk chalk I have been coming up with a blank.  Any new/creative ideas for this product?

So long and thanks for all the arduinos

Adios, everyone! Tomorrow is my last day here at Instructables and even that will mostly be clearing out my desk and distributing materials for future projects. First and foremost, I love you all. If you're here reading this then you're someone who has chosen to dig into the world and learn much more than most of the people out there. That's a cool thing. An amazing thing. Cherish it and make that grow within everyone else you know. More is more here. Also thank you to everyone for sharing your ideas. One of the biggest things I've learned is that you should share your ideas with others. There will always be more ideas and it's more fun this way. I wish I had a couple more lifetimes for the ideas that I'd like to work on. It is way worse to live a life keeping an idea secret for fear of someone else stealing it and never seeing it develop. OK, going into debt to patent it would probably be worse. Is this a graduation speech? No? Fine, here's some unsolicited advice anyway: run into new areas. Don't give yourself a chance to think about it and go back to doing what you've already been doing. Mental ruts are comforting, but oh so boring. Listen to music you don't know, watch movies you know nothing about, just shake it up once in a while. No, shake it up all the time. The world is full of new ideas you've been depriving yourself of enjoying. Then when your brain is thoroughly jumbled, start mashing up all the ideas. Combine all the things! One idea I want to work on is to make a UAV candy bomber. Attach candy to parachutes and drop them from quadcopters as they fly around in the sky. It would be a modern version of the candy bombers from WWII. It's not about anyone getting the reference, that's for wikipedia. It's about moving faster. Worrying about originality is for people who don't do stuff. And that's the long version of saying that I'll be gone from here, but you should all keep the party going. Then again, you were going to do that anyway and that's why I love you. For me the future is a little uncertain. There are a couple of VERY COOL THINGS that might happen, but it's not definite yet. In the meantime, I'm wrapping up my kickstarter calendar project. If you haven't looked at it yet, please do. The calendar is awesome and I want more of them out there in the world. Other than that you can find me on twitter as @edabot.  Now stretch your arms out wide and then give yourself a hug. Pat yourself on the back if you want. You're the future if you want to be. Take it, it's right there. Love you all. Ed

A lamp from RGB LEDs

Hi, I'm want to build a lamp from 63 RGB LEDs. I want to be able to change the intensity of each color. Is there something in my schematics that should  be changed, for example do I even need the resistors after LEDs since I have the potentiometers. I think the values might need to be changed. The switches before resistors are to eliminate that color if the potentiometers won't do it. There should be also a main switch after the power supply.. Do I need anything else, so that it will work and to it will be safe? A bit offtopic, but if I would only use one color LEDs, would it be better to connect them to parallel or series?

flashing LED - first project

I'm eager to start my first project, but I don't know how to do it. Its basically an LED blinking twice, once at every 20 min. I can tackle it in Arduino since its code, but I need something really small, the smallest possible! (the way that would be powered also needs to take this into account. a 9v battery would be too much. but If it could have a way to be powered by USB that would be great). The closest I can find, is something similar: A fake car alarm, that flashes a red led. But I need to have the 20min spacing!  Can I have some shared knowledge ? :) Thank you!

How can I make a cheap projector screen and free-standing frame?

Dear all, recently I commissioned and received a portable-ish movie projection unit that will let us show movies almost anywhere - in back yards, against buildings, in parking lots, and so on. It's designed for a guerrilla cinema experience for the community. See here for more information and a cheesy video I made for it. However, there remains one big issue: The screen and its frame. This is for the occasions we won't have a white blank wall to use. Can you geniuses come up with any suggestions? There are a number of features that are necessary in both elements:- 1. The screen Lightweight Cheap-ish Rolls up Doesn't easily crease, dent, rip, etc Isn't easily damaged by a small amount of fog/rain Can accommodate up to 12ft wide 16:9 images 2. The frame Lightweight Cheap-ish Can be quickly and easily disassembled to be carried short distances Is adjustable in terms of height and length (not essential, but would be nice) The screen can easily be attached to it Do you have any ideas as to how this would be possible? If so, I'd really appreciate it. Thank you!

Is it ok to post it?

Hey Instructables! So a couple of weeks ago I finished a year long project, automating my room. The project is completly modular so if any piece burns out or fails you can quickly switch it, the project includes automatic lighting controlled via a PIR sensor, an LM35 controlled fan, a miniature green house controlled by another LM35 and it displays the info about humidity and temp, through a 16x2 lcd and DHT11, a combination lock for my door via a keypad, a infrared control that can turn on or of my desk lamp, alarm clock, room lights, solder station and has the function to turn the whole system on or off, it also includes a modified Sony alarm clock, that has a TDA2040 amplifier with aux in and its connected to some speakers around my room. I have all the eagle files and ready to print pdf´s. Everything is controlled by 2 DIY arduinos. I made most of the modules for the sensor array but a couple of the controll modules were made using already existing files on fritzing, and the DIY-Duino Should I redesign this modules and controller board before uploading, or will crediting the authors of this parts will do?

Motion Triggered Horns

I'm starting this one over, I made a mess of the last topic. Essentially what I'm starting with is a driveway wireless alert system (  and a car horn. The car horn is wired to a push button switch. ( What I'm trying to do is replace the [S] (switch) with this wireless trigger. The alarm speaker outputs at a very low voltage, ~0.08v: The alarm LED's output 1.75v (measured from + on the one LED and - on the other, there are three total, in series) What would be the best place to tap in to get voltage from to trigger the relay? I think from the previous post I'll need a transistor switch of some sort? This is the part I need help with. Usage: Tractor pulling hayrack riders over a bridge, I'll place the sensors ahead of the horns so by the time the tractor is at the sensor the hayrack is right at the horns.

Suggested feature: selectable images of tools, materials

I often find myself making little Photoshop collages of tools when I'm working on an 'ible, just so there's something to look at on the less-than-riveting steps where I'm listing what tools and materials were used. And I see that lots of other folks find themselves doing the same thing. And let's be honest: we're all kind of phoning that part in, aren't we? What if we had the option to jump to a screen with tons of selectable tools, do a little clickety-click, and go back to our 'ible to find all of the items we selected displayed in a visually economical and aesthetically pleasing manner? Stylized icons, photos, or even sponsored images from advertisers linked to their shopping page? It would help the folks struggling with their graphics software, and help the folks who aren't struggling but would still rather dive right in to the "how-to" part, which is why we're really here. The possibilities are endless for the GUI, ranging from simple checkboxes, to drag-and-drop images, to a complete overkill of awesomeness where you click an object and an animated Instructables Robot walks over and grabs it and drops it onto your virtual work bench... Anyway, that's the idea. What do you think, folks? Mike Craghead

Exchange Tshirt for a larger size?

Hi friends....I love this site and do like to win, even if it's just a bunch of positive comments!  Recently I won a t-shirt and I didn't realize how small/close the sizes run.   (I believe I requested a women's large and in the comments I noted that I wanted the equivalent that would fit a women's chest 36-38".  I was disappointed that the Tshirt ran exactly 37" with no room to breath.  Unfortunately I didn't realize I was supposed to add a few inches for movement as none was built into the size.) My shirt has not been worn and it still has the manufacturer's paper tag attached.  Is it possible to return it to Instructables for a larger size? If so, then I'd like to request something that measures 42" from armpit to armpit - which would be great after shrinking!  (I realize the larger size may be considered too large for the female sizes available, and if so, the equivalent man's size would be appreciated over one that doesn't fit) If this isn't an option, perhaps future winners can be asked what size they want their shirt to run "from armpit to armpit".  Not only will this make more T-shirt winners be happy, but also, more Instructables advertising will be seen on the streets ;-D mega thanks!

Full Spectrum Lasers

Hey Everyone, Recently I have been looking at different C02 laser manufacturers to see if there was anything that was affordable but still of professional quality, and I stumbled accross Full Spectrum Lasers.  I am wondering if anyone on the site has any experience with their products and their customer service. The reason I am asking is because their prices almost seem too low; comparable Epilog lasers seem to cost at least twice as much.  I know that Epilog is probably one of the biggest names in the industry and have apparently been around the longest, but I don't see how that alone could cause such a price difference. So basically, if any of you have had good or bad experiences with Full Spectrum your knowledge would be greatly appreciated. Nathanael Scheffler

It sounds very interesting and i'd like to experiment with it.  After some reading ( I found that all you basically have to do is send a sinusoidal wave through a conductive surface. This can be and amplified DC signal. In the paper they talk about a Vpp (peak to peak voltage) of 120V at a current of 0.5mA and a 80- 400hz. frequency. My question is: How to amplify a generated sinusoidal signal (0-5V, 80-400 hz.) to a signal of 0 -120V and limit the current to 0.5 mA so i can use it for some experimentation? Cheers, R.

While all the articles which have been taken from the pages of the magazine & published as 'ibles are well written & informative they are also a blatant advert for both the site & the magazine & as such in my eyes at least are spam, I know that there have been a few 'ibles published by Pop Mech in the past but I really feel that fifteen or more all at once is extracting the urine just a bit when it comes to copping for a bit of free advertising.
