ok thank you.
2  Using Arduino / Motors, Mechanics, and Power / hobby motor: only + and - [SOLVED] on: April 16, 2013, 10:46:50 am
in the arduino cookbook and fritzing, the basic example of a servo motor seems to have a third cable which receives the PWM signal from arduino. the motor that i have only has positive and minus leads. i was able to get power to it and make it spin, but not sure how to control it?

it looks like this but it's plastic:
 

the yellow cable?

thanks, this is really interesting to me smiley

thanks. what is an example of a high power LED with a driver ? maybe on a site like adafruit?

and how does the relay work? (i imagine it's something like when you put your lights on a timer)
5  Using Arduino / Project Guidance / what's a bright light to use? on: January 03, 2013, 02:11:59 pm
i'm looking to make a series of floor lamps to use on a stage setting. the simple LEDs that I have are clearly not bright enough.

so what kind of options do i have for really bright LEDs?

and how would you control a bigger light with arduino? say a normal lamp?
6  Using Arduino / Audio / Re: Record and playback music/sounds not using shields on: May 19, 2012, 09:40:20 am
Visit Atmel.com, there is application note AVR335, with a "recorder" code

http://www.atmel.com/dyn/resources/prod_documents/doc1456.pdf

"This application note describes how to record, store and play back sound using any AVR microcontroller with A/D converter, the AT45DB161B DataFlash memory and a few extra components."

Sounds take up a LOT of memory.  Where do you plan to store all that data?

if you're making short loops, can't you store them on a small RAM chip? if so, which chip are you looking for and how does it connect?

looking into making something similar to these "virtual turntable" surfaces that have been cropping up in the past few years. a motor spins a lazy-susan around, but if you touch it, it will stop the motor and send a signal back to the computer to stop playing the music (or find a new spot in the song).

here is one by numark that gets the concept across:

i agree, would be nice to know more about them. also anywhere to buy them in toronto ?

well you sir are a wealth of knowledge! yes i am definitely thinking about psychedelic rigs because i know they were low-tech and low-budget. lots of great ideas in your post that i really have to go through and digest. any added photos would be of great help to see exactly what you mean.

thanks that's really cool: http://petemills.blogspot.com/2011/03/cigar-box-laser-light-show.html

keep 'em coming folks!
11  Using Arduino / Project Guidance / visuals for a small bar on: March 15, 2012, 10:43:24 am
i'm looking to aquire some tools that will help build a nice, small, flexible kit for doing visuals in smaller venues. i am not tied to using projectors because they are large and expensive. i am more looking to make use of things that reflect, or create shadows. sorry this is vague but i dont really know where to begin.

one idea i had was putting some paper birds on a string and having a motor move the string. a light source would cast a shadow of the birds on to the wall, and they're moving with the music. stuff like this.

i might going the route of making little felt modules with the ports on them. nothing would be sewed down but i know that the tin can be used this way. would love to know any more ideas from people doing something similar!
13  Topics / E-Textiles and Craft / Re: does anyone use jumpers on clothing? on: March 12, 2012, 10:15:07 am
thank you. yes i was pointed in this direction of using tin wire and it looks like a great option. i am going to add connectivity using little pin headers and sockets to make the paths a little more modular.

the only problem with tin wire i can see so far is that it can get tangled easily, and bunches up in spots (making mini hooks).

i am looking to add ports to my lilypad pcbs so i can make my shirt more modular and not sew every connection into place. has anyone integrated jumper cables like these (with female connections)?

yes i'd reckon it's similar to the ethernet shield, involving setting your MAC address and the like in your sketch.
