is it possible to store an arduino library on eeprom if it is big enough?

I was wondering if you could store an arduino library on an eeprom chip because the sound library for the waveshield kit is very large (~10KB according to she had also stated under the waveshield tutorial that it is too much to store on the ATMEGA328's eeprom. she didn't say anything about other eeprom chips. i was wondering if it is possible to do this because she had stated that there is not enough eeprom on the arduino chip.

15 steps to starting your own electronic-kit business - ladyada's tips for success

Voices: 15 steps to starting your own electronic-kit businessLadyada, of MintyBoost! fame among others, gives EDN the step-by-step process for building a successful kit-building business. I've seen her operation, and she's a total pro. If you're interested in doing this yourself, this information is gold.After Limor Fried received her master's degree in computer science and electrical engineering from the Massachusetts Institute of Technology in 2004, she started her own business designing and selling electronic kits, targeting customers who want to explore embedded-microcontroller-based designs or create their own GPS (global-positioning-system)-based systems, among others. She has made Adafruit Industries into a successful electronics-kit business, and, based on her own experience, offers these 15 practical steps for engineers who dream of starting their own kit business. Plus Step 7:Put basic documentation of your project online. You can use the or the site. Put the picture at the top of the project page. Below that, place a one-paragraph description of the project with specifications. For example, if you built a DMX-controlled RGB LED light, your paragraph should describe how bright it is, the DMX-control functions, how many LEDs it has, and why it's innovative. People who will give you publicity are busy, and you should make it as easy as possible for them to copy and paste your photo and description to their blog posts. Repeat this step for each project.Check out her site at

My POV Toy!

Woot!I finally finished my version of ladyada's miniPOV.I just made it a bit smaller and used a header for programming rather than attaching the 25 pin D connector directly to the board. Oh - and almost all of my supplies (except for the board) were free =DD.-->Check it!-T3h_Muff

A VERY simple Arduino Servo Tutorial?

I'm pretty much new to the arduino stuff and I was planning on making a biped robot. But first before all of that I need to know how to use servos. :P Is there someone out there that can maybe post a very easy to understand tutorial of how servos work? I've read ladyada's tutorial on the arduino. So basically I understand all of that but I'd like to know how to control servos and how to program them.

I want to make a iphone 4 compatible 9v charger. How would I simulate an apple charger? Answered

I went to ladyadas website, but I don't understand exactly how one would do that.  I am using a switching 5v regulator for more efficient power.  Please no circuit diagrams because I don't understand them, unless they have explantions.

Do you HAVE to have a socket for an 8 pin microcontroller or can you just solder it directly to the board? Answered

I'm trying to put together a Tv-B-Gone with the Microcontroller from ladyada but they don't send along the socket (I had the rest of the parts already from other projects and just needed the microcontroller and socket) and its not at Radioshack either. So I'm wondering how important that piece is? Can't I just solder it directly to the wires? Or is there something specific that I'm failing to understand? In a dire need to learn, thanks.

How can I read a txt file to a string on an Arduino?

I have an Arduino combination SD and Ethernet shield.  I need to use them together, but the Ladyada tutorial does not work with my hardware.  Basically, I set up the web response to my client, then turn of the Wiznet chip, read the file, trn the Wiznet chip back on, and finish sending my response.  The problem is, I need to write the txt file to a temporary string so that I can turn the Wiznet chip back on and then write the data.  Any help?  Thanks in advance.

Is it possible to etch PCB's with HCL? Answered

I bought one of ladyada's USBtinyisp avr programmers a few days ago, its working great! i program alot in visual basic but i never tried anything quite like the C similar programming of the avr chips. because of that i reprogram my chip ALOT, so i decided to make a target board. i already have the "blank" board and a UV lamp to prepare it. i have sodium hydroxide to develop it. all i need is something to etch off the copper. so i was wondering: can i etch off the copper with 32% hydrochloric acid/muratic acid/HCL?

Instructables Internship - Day 1

Hello from Instructables HQ!*Last Saturday, I flew down to visit Instructables. I stayed and poked around San Fransisco over the weekend, but today I started my Instructables internship!(Sadly, I left my camera at home, and I don't have nearly as many pictures as I'd like)I arrived at the control tower, and was greeted by [/member/numberrandom Mitch] and [/member/fungusamungus Ed], and [/member/candia Christy] & [/member/ewilhelm Eric] arrived shortly thereafter. I was shown around the place, and then I started to get working. I got to take [/member/noahw Noah]'s desk, since he's out for the week. (Probably chasing [/member/T3h_Muffinator Muffinator] to get Project X's instructable done...)Soon, [/member/rachel/ Rachel] walked in, and helped me get a copy of the database working, so I could start working on site-related things.While the computer was chugging away (as it did for the rest of the day), I walked around and met [/member/randofo Randy], and a few other people. Randy explained to me some of the cool things that he's working on, and I offered to help. Somehow, we stumbled upon the idea of drying clothes by microwaving them, and we were really close to actually trying it...Later, I started assembling and documenting [/member/ladyada Ladyada]'s (seealso) TV-B-Gone kit. I didn't get to finish it before the day ended -- it just flew by!Everything was going great. I had been extremely excited for this opportunity, and its even better than I thought. Everyone seems interested in each other's projects. Its really cool.I can't wait until tomorrow, where I hope I get to do more exciting and fun stuffs! Yes, I said stuffs!* okay, I'm not there right now...

Extremely urgent!! I need help figuring out how to connect an alarm to a PIR sensor! Answered

Skip to the second paragraph if you are short on time or get sick of me droning on.              Okay, so you've just done the first step in helping me, reading this.  Me and my dad are sick of having our pumpkins trashed on Halloween just because someone doesn't like our football team. (there are other reasons too but that could take a whole book and a month to explain it)  We live in a nice neighborhood where everybody knows everyone and things are pretty nice.  However there are some people in our neighborhood who just don't give a freaking crap what their kids do, and I'm sick of it.                         So I have a PIR sensor, Ladyada explaining how to use them, RadioShack, and Adafruit Industries.  I also have an extremely loud alarm that goes off when the circuit is broken.  I need some help figuring out how to make the PIR sensor break the circuit on the alarm.  I have included a diagram explaining.
