Arduino - Basic Kit - Instructions?

I purchased the Arduino Basic Kit a number of years ago. The directions say to go to Autodesk.com/Adruino to get started, but that page doesn't exist anymore. Does anyone have a PDF of the project directions for the parts included with the kit? Thanks.

Need basic CNC info please

I am in the process of learning SolidEdge V19 by myself (It's CAD program, if anyone is wondering). Now I know it may not be the best place to start learning CAD, but I got it for free. I am quite new to CNC machining and CAD software and I need some clearing up on a subject: In what environment do I need to draw the parts in order for it to be used CNC? I am only working with sheet metal and have all the precise dimensions of the parts that need to be cut out. Should I create the parts in the drafting environment and then export it as a .dxf file which will be used on the CNC? Sorry if my question sounds a bit, you know, stupid, but I just need some clearing up on this issue.

How can I make a easily distributable .exe file in Visual Basic 2008?

I'm making a couple of programs in Visual Basic 2008 Express Edition, however once you publish it the files are darn hard to distribute. If you move it it won't install correctly and if you ever try uploading 3 files to a webpage asking people to download all of them they're likely to just ignore you. So I would like to be able to mix all those files into one single self-contained .exe file which can be copied or moved as much as the user wants. Can I do it? All help is appreciated.

Basic electrical help needed? Answered

Hello everyone i'll try to keep this short and sweet. In my next project I will be re-Building a trolling motor. The trolling motor runs on a 12 volt battery, and draws between 5 to 30 amps. The problem I have is that the control unit/head of the trolling motor is destroyed. In other words all i have at this point is a 12 volt motor connected directly to a 12 volt battery. The trolling motor is very powerful and I don't want to run it full power all the time. This made me look for a 30 amp dimmer switch, just like the ones people have in their homes. With no results I don't know what to do. I am thinking about using a 600 watt AC dimmer switch like the ones in peoples homes, but I don't know if it will work with a DC circut like the one I have. Thanks for your time and help.  ~KayakKid

What are the basics of power supply mechanics to voltage and RPM's in micro vibration motors?

I'm trying to make several different versions of vibrating plush toys so I can find out what the ideal vibrating feeling will be for toddlers and babies. Too high an RPM can be scary to a little kid. I'm a beginner with little/no knowledge of basic electronics, but a capable tinker and solderer. I'd like to understand the basic logic of power supplies to micro motors and how to arrange the basic wiring. I've seen lots of instructibles but I can't find a simple explanation of this kind of thing. I've got a Radio Shack 3VDC vibe motor. no-load speed is 16K RPM. I tried wiring it to a two-AA battery enclosure (2x1.5V=3V?) and it wouldn't run. Touched leads to a 9V and it powered up but RPMs are way too high. Some related questions: 1. Can you vary the voltage to a typical micro motor and get different RPM's? 2. What's no-load speed and do I need to worry about it? 3. What kind of switch can I use to power on/off 4. How do you tell what kind of battery config to use with a motor

heliostat and sun tracker basic program

In the late 1980s, I designed, built and programmed a computer-controlled heliostat. Its mirror reflected sunlight into my living-room, making it much brighter. It worked excellently with almost no attention for many years, until a neighbour's tree grew and blocked sunlight from reaching the mirror. The computer was a Commodore VIC 20, which was old even then, and had only 4.5 kilobytes of memory. The program I wrote, in Commodore BASIC, fitted into that space and handled all the control functions. It even included a few "bells and whistles". For example, at night-time the mirror was automatically parked face downward to reduce the buildup of dust. That particular program would work only on a VIC, and I haven't seen any of those for many years. However, I have recently taken the astronomical and trigonometrical parts of the program and made them into a new program which I'll append below. It calculates the position of the sun in the sky, as azimuth (true compass bearing) and angle of elevation, as seen from anywhere on the earth at any time on any date. It also calculates the required orientation of a mirror if it is to reflect sunlight in any desired direction. With the addition of some code to enable the computer to control motors, this could become the software for a computerized sun-tracker or heliostat. I'll append two versions of the program. The first is in QBasic, and contains quite a lot of explanatory comments. The second version is in a very generic BASIC, and has been tested on many implementations of the language. It even has line numbers! Personally, I prefer the QBasic version. The coding is more elegant. However, the generic version is likely to be useful to more people. It's public-domain. Use it for any purpose, even commercially. Enjoy! dow ' SunAlign.BAS (Version for QBasic and similar dialects) ' Calculates position of sun in sky, as azimuth (compass bearing ' measured clockwise from True North) and angle of elevation, as ' seen from any place on earth, on any date and any time.

how do i run a timer on a separate thread in visual basic so it doesn't lag?

Hello, I am currently writing a program that records the mouses position over a 256x192 px box, then spits it out every 67ms in the form of dsgamemaker xds code which can be pasted into the project code, to make a sprite move on the exact same path as the mouse moved during the recording. A problem i am having however is that the timer event i am using to move the cursor representative sprite ( which moves with the D-Pad up down left right), when i begin recording, the sprite moves very very slowly because the frame rate is so very slow. as a separate timer event from the recorder, it moves slow, but when all the code is as one entire timer, it moves at literally 3 pixels per second. however this does not affect the generated sprite cut-scene. Ive read that if i put this timer  on a separate thread, that it will run independently from the other timer which will stop the lagging. but the problem is that i cannot find a single example online which shows how to do this, and the ones that do show, don't work. does someone know how i can make the timer run on a different thread? or even a different core for that matter, so it doesnt lagg? Im puzzled as to how other applications can do this, increasing a value one at a time, at such a high rate, when the timer event, will never do that. is there some other way to run looping code like a timer event? Your help would be greatly appreciated. ill post the application soon to show you exactly whats happening also im running VB 2008 express

Calculate Resistor for Heating Wire

Hi there, My Goal is to use a piece of heating wire from an old hair dryer  (1.6 Ohms resistance for the length i want to use.) and heat it red-orange using my old USB power bank. 5V output from an 3.8V lithium ion battery i dont want to mess with the circuitry inside. Problem: The USB Power Bank has short curcuit prevention built in, so when i connect the heating wire the power bank stops supplying electricity. I found a 7.5 ohms resistor and connected it aswell, the wire became a little warm, the resistor incredibly hot but most importantly the power bank continued to supply power - success. I would like to know what resistor i should use to get the wire red-orange hot but at the same time keep the power bank safe and not overwhelm it - i think that would mean not drawing too much current? I also cant check how much current is flowing because my multimeter is too cheap and only goes up to 200ma, which the power bank exceeds. So how would i go about this? What resistor should i use for what wattage should it be rated. And since im a total newb id like to hear your train of thought as to why and how. Thank you so much.

There are no big special features other than the magazine which is obviously removable and has an internal pusher, a roof, and it can be top loaded. With a quick change of pieces you could technically top load the magazine while it is in the gun though it may be a little tricky. The magazines slide right in and should stay put. I shaked it my hardest and it wouldn't fall out. Removing it is pretty simple. You just need to pop both sides individually. As you can see I ran low on pieces so I just used red rods for the stock. You can store an extra magazine in it like in the picture. Of course I put in a pin guide. The handle is average. I wasn't too concerned with it as people can mod it freely. The trigger was made to block farther back so that the gun wouldn't have to be a unit longer to get max power. Ranges with the rubber bands placed as shown were about 9 meters or 27 feet with the mag full. I suspect increased ranges as the magazine empties. It doesn't have a turret, bolt, or shells so I don't know if you consider that good enough or not.

Can you help me convert some Basic code to Processing code for calculating 555 IC timing?

I want to modernize this BASIC code that I found for calculating the values of capacitors, or resistors to use for timing with the 555 IC. /* This BASIC code taken from the Ramsey Electronics Universal Timer - Oscilator Kit UT5 instructions I decided to convert it into processing since no one really uses basic like this anymore.

How to Identify homemade USB device connected to computer by passing some identification tag?

I'm planning on developing several different USB devices that will be operated by a Visual Basic 6 program I am writing.  I want to be able to identify the USB device plugged into the computer the same way a program knows when you have just plugged in a USB drive or webcam.  Is there some simple cheap way that I can wire in a circuit that will pass an identification tag so my program can identify which USB device has been connected?  There are certain criteria.  The parts must be cheaper than a usb flash stick...otherwise I'd just disassemble a flash stick and load a program to it to automatically run telling the usb ID.  I'd rather not do this simply because I'd rather not have to take apart several usb flash drives which can get expensive.  This eliminates Arduo and other costly circuit boards.  The parts when assembled need to be smaller than  a usb flash drive.  I just want to pass some ID serial number to the usb port that I can than pick up with my program so it knows that device has just been plugged in.  Any suggestions?

A 'simple' sound activated LED.

Soooooo, I don't have a whole lot of knowledge about electronics. But I'd like to make/have someone make a single LED bulb that lights up when a microphone recieves sound. I'd 'actually' like to fit a small microphone into a helmet's mouth section, and have an LED activated on the outside. If it's possible to incorporate a speaker on the outside as well, that'd be incredible. And even more-so, if it could change/amplify your voice on the way out, that'd be simply orgasmic.

What are the guidelines for your power voltage path in your audio project?

Are you supposed to avoid crossing it over your audio signal, or parallel to it, or across or parallel to your ground wire?  And if the enclosure is grounded, should you avoid running it against the enclosure?

How do I use a timer to turn LEDs on one after the other?

I need to find a way to have a series of red LEDs turn on one after the other, as if it was a snake, moving along a line, or a laser pointer, slowly turning on, the lights being the laser beam... How would I do this with basic circuitry knowledge and a tight budget (less than 20 dollars)?

Natural electronics

Ive been making tons of projects lately and i keep asking myself the same question. What is going on in those little components i solder on. Say i was to take resistors, capacitors, transistors microchips etc... and snap them in two, what would I see? What is it that allows people to program microchips, Is it essentially typing code and sending it into a natural resource? What allow wire to carry information? Does anyone else ask themselves these mind boggling questions? Or better yet does anyone have answer?

What Do I Need To Change In Order To Run This Circuit With a Button Cell and a Momentary Switch?

I'm trying to do a modification to this project here. I need to replace the 9v battery with a smaller one, probably a button cell or similar, and the slide switch with a momentary one. This is my first real electronics project, so I'm not sure how those changes might affect the rest of the components. Do I need to swap out any of the materials listed in the Instructable to make that work? (Besides the obvious momentary switch, button cell battery, and battery holder) I asked there, but I've yet to get a response and thought that maybe this would be quicker.

Yabasic (for the PS2)

I found Yabasic as an extra for a PS2 demodisc, and i recently dug it out from my Ps2 pile. it is a fun and simple piece of software for creating small programs, in which you type a command (eg. print, input, goto, beep etc.) and then a piece of text. here is a code for a simple number guess program, sorry for mistakesREM Number guess gameprint "I am thinking of a number between 1 and 50, try to guess it!"input a$if (a$>13) thenprint "your number was larger than mine!"goto inputendifelseif (a$<13) thenprint "your number was smaller than mine!"goto inputendifelseif (a$=13) thenprint "My number was 13! Congratulations, you win!"Feel free to edit the prints, and the number doesn't have to be 13. there are other things involving string variables and other commands. heres one called identitiy finderREM Identity finder programPrint "What is your name?" :":input a$Print "How old are you, ",a$,"?" :":Input b$Print "And where do you live, ",a$,"?" :":Input c$Print "so your name is ",a$,", you are ",b$," years old and you live in ",c$,", correct?"Pause 5Feel free to add more string variables, just add them as d$, e$, f$ etc.anyway, post coding for more yabasic programs, and use the stuff above!

I assume i would need a large capacitor but am just going for a general question about how it would be in programing? Also i took apart a grill lighter and found the igniter... I'm wondering weather that uses the energy that you push on it to spark or if it has a battery. Thank you!
