Individual upcycling!

Dear all,  I am a PhD student in the School of Architecture, Design and the Built Environment, Nottingham Trent University. My research is on ‘Individual Upcycling’ – creation or modification of any product out of used materials in an attempt to create a product of higher quality or value than the compositional elements at the household level (including creative reuse and refurbishment). Would you be kind enough to go to the link below and take 10 minutes to complete my online survey? http://goo.gl/forms/8AnVU9fwCw  I need around 50 people for the pilot study hopefully by end of this Month. Your time and participation will be very much appreciated! Thank you very much in advance for your kind help. Yours sincerely, Kyungeun Sung PhD candidate Nottingham Trent University

Is there a way to control many (120ish) LEDs using a computer without having to control using a matrix array?

I am trying to make a learning guitar that has an LED at every fret (so around 120 individual LED outputs), and after lots of research I am finding it difficult to find a way to control that many LEDs individually. I want to be able to turn on multiple LEDs at once for a chord so using a matrix array will cause unintentional LEDs to come on.

Individually Addressable Speaker Array

Hey! I had an idea for an array of many small speakers, each capable of playing different sounds so I could dynamically re-arrange which speaker is playing what. This would be paired with some LEDs and some water to make (what I hope will be) a fantastic visual effect. But of course all this is a bit over my head, so I'd like some feedback on my idea! After a bit of research, here's how I think I'll do it: General Concept Essentially what I'm trying to do is make a waveform generator with lots and lots of separate channels. I would hook up my microcontroller to several, multi-channel Digital to Analog Converters (DACs). The microcontroller would feed these DACs signals to generate the wave forms that I want for each individual speaker. The waveforms that the DACs output would each go through an extremely simple amplifier. The amplified signal would go to my speakers. I've attached a diagram that should give you a better idea of what I'm doing. Specifics The microcontrollers I'm looking at are the ChipKIT series from Digilent because I have access to a bunch of these. I'm currently planning on using the uC32, but I actually have access to pretty much all their other boards. The uC32 runs at 80MHz. The DAC I'm looking at is the AD5628 from Analog Devices. That's used in Digilent's PmodDA4, which I also have access to. Alternatively I might just order a bunch. They have 8 analogue outputs, and the SPI communication can run at 50MHz clock speed. I'm planning to have eight of these (for 8^2 total outputs). I haven't figured out what amplifier I'm going to use yet. It'll need to be simple and cheap, as I'm expecting to have 8^2 of them, but I'd also like one that can operate over a large band of frequencies. I've also attached two pictures of the speakers I'm planning to use. I kinda randomly acquired a lot of these, so I'd rather not switch to a different speaker type. According to Wikipedia, the highest note on a piano keyboard is a little over 4kHz. If I split the sinusoidal wave into 16 segments, that means an update frequency of 76kHz. This is way below my max operating speed of 50MHz so I think I can get away with it. Questions What am I doing wrong? I'm hardly an expert on any of this, so I'm certain there's a much simpler way. Are there ICs that do what I want? Maybe something that takes in a digital signal and outputs waveforms? This would be similar to how a servo controller would output different PWM signals, only changing the frequency rather than the duty cycle. What sort of amplifiers should I be looking at? This is my first time on the forum so please let me know if I'm doing anything wrong (or could do anything better).

Powering a lot of individually addressable LEDs

I have been toying with an idea for a while of making permanent holiday light fixtures with individually addressable LEDs. The problem I continually run up against is that these types of LEDs all run on 5v power, I believe because of the driver that controls them. They have high voltage AC strips, but they aren't addressable.  If I take Adafruit's "Dotstars" as an example, they require 60ma of power per led at full brightness. A typical holiday display may require up to 250 feet of lights. If those lights are spaced at a typical 2.75 in apart that's 1091 lights. This becomes 65455ma or 65.5 amps of power. That's a stupid amount of power required for some holiday lights. Are there any high voltage individually addressable leds on the market? Is such a thing even possible? If not, is there some type of wallwart that might help me solve this problem in a safe less power hungry way?

individually addressable led DECORA switch

Greetings collective Instructables genius, Here's the deal, I have a kitchen,  I also have several strips of individually addressable LED's powered by the same supply.  I like the led's, I really the fade between teal and blue as it gives the impression that you're underwater.  At any rate, having anything other than a decora sized switch is out of the question.  I don't need another remote, or some box with switches on it to control the LEDs.  I'd really like a switch that can be mounted in a single gang electrical box, that can be covered by a decora faceplate.  I have a media cabinet where the power supply for the LED's is housed, and the switch can run to the supply in the cabinet.  I need at least 4 programs (like the underwater effect), though 8 would be ideal.  Any thoughts on how to approach this?  I'd spend upwards of $80 for a finished product.   Any input is appreciated.  Thank you Eric

Bunion separators made to suit an individual

Hi there, Does anyone have ideas on how to make/get hold of a silicon type material to make moulds of so called toe separators.   Something which could be made to an individual's needs, i.e. I would make it for myself and if it works, to share it publicly, as I am sure those who suffer from having bunions would benefit extremely.  Unfortunately the products available on the market most of the time don't work (and is waste of money and resources), as all of us have different toes, feet, alignments etc. Any ideas on how to make such material at home and cheaply are very welcome. THANK you in advance! To peace and comfy feet for all! P.S. I have attached a few photos of these products to give you an idea of what I mean.  The silicone which is used is soft but sturdy enough, which doesn't hurt the joints of the toes.  It would be great to be able to mould these around flip flops (and other shoes) permanently - so that they don't move about.

Way to control two fluorescent bulbs in the same fixture individually?

I would like to set up a few fluorescent light fixtures that each have one blacklight bulb and one white bulb. I would like to be able to control them individually so that I can have either the blacklight bulb or the white bulb on at any given time. It would be preferable to be able to dim the white bulbs, but this isn't necessary. I am okay with running a 14/3 power cable assuming two ballasts would fit in one fixture. I would also like to accomplish this as cheaply as possible.  Thank you.

There are many occasions where I want to cross-reference somebody's comment in another posting. Most of the time, I try to use the "date and time" stamp, but that's problematic since the time is computed on the fly in my local TZ. It's worse if the comment is embedded half a dozen layers down in some thread in a completely different Forum Topic. Once or twice, I've tried to use "View Source" in my browser, and search through to find the corresponding markup for the comment, and then extract the hash from one of the tag/JS attributes. Since the information is already there, would it be difficult to add a "link" hyperlink to each comments, such that the returned URL was the one needed to get back to that comment in the future?

Re-Use, Individual Cells from 18V NiCad

Seems that with a bit of randomnity in mfging, some cells in an 18V battery might fail before others. With that in mind, I'm trying to re-use individual cells after a pack craps out.  Test 1  Battery pack from a "drill master" which I got for  ~$2 at a thrift store. Google informs that this is a harborfreight tool, so expectations are low.  Upon disassembly of the pack, 1 of the spot-weld connections between cells had broken.  Since I don't currently have a 1.5v source, I'm using a 3v  source to charge 2 cells in series. Only charging for a few minutes at a time. Currently, this 2 cell set will light a couple xmas lites for a few minutes after charging for a few min. I'm uncertain of the calibration of my v-meter, but it currently indicates 2.65v for these 2 cells. Depending upon the source, NiCads should max out at 1.45 to 1.65 v per cell. Test 2: Pending- Ryobi drill batteries I'm uncertain how to get a good read on the accuracy of my meter without a high-end meter to compare against. Suggestions? Hopefully, I can find a proper 1 cell nicad charging device.  Thoughts? concerns? insights?

RGB LED Life Bar, 10 Sections, Individual LED Control, Arduino

Okay, I want to make a "Life Bar" using an arduino controller, 10 RGB leds, and a clear plastic box with ten sections. I'm going to mount this on a wall in my room. Each section will be diffused or frosted and will be 4 x 4 x 4. One RGB LED will in the "back" of the section, with the wiring, coming out of the back of each section. The controller will be to the left side of the total ten sections, with the USB port having easy access. I think I'm going to have one switch to control the modes of the LED and cycle through each mode, which would reset after the lowest "health" of the bar is reached; RED BLINKING >> Press Switch >> FULL HEALTH. I'd like to control each LED individually so I can create a diminishing "Life Bar." Like this: (Colors of the LEDS) OFF = No Color, LED not LIT BLU = Blue AQU = Aqua GRN = Green YEL = Yellow RED = Red REDB = RED Blinking So: Phase One (Full Health. HAHAHAHA I'M INVINCIBLE.) |BLU|BLU|BLU|BLU|BLU|BLU|BLU|BLU|BLU|BLU| Phase Two (I tripped whilst fighting.) |OFF|BLU|BLU|BLU|BLU|BLU|BLU|BLU|BLU|BLU| Phase Three (I'm hurt a little, but I'll be okay.) |OFF|OFF|AQU|AQU|AQU|AQU|AQU|AQU|AQU|AQU| Phase Four (I should probably start looking to see if there are any potions around.) |OFF|OFF|OFF|AQU|AQU|AQU|AQU|AQU|AQU|AQU| Phase Five (Green? Green is good.. Right?) |OFF|OFF|OFF|OFF|GRN|GRN|GRN|GRN|GRN|GRN| Phase Six (It's okay I've fought this boss before at much less health.) |OFF|OFF|OFF|OFF|OFF|GRN|GRN|GRN|GRN|GRN| Phase Seven (This boss... This boss can breathe fire now..?) |OFF|OFF|OFF|OFF|OFF|OFF|YEL|YEL|YEL|YEL| Phase Eight ('Tis but a Scratch!) |OFF|OFF|OFF|OFF|OFF|OFF|OFF|YEL|YEL|YEL| Phase Nine (HEALS HEALS HEALS HEALS PLEASE PLEASE ANYONE.) |OFF|OFF|OFF|OFF|OFF|OFF|OFF|OFF|RED|RED| Phase Ten (Okay, I have almost no health, my party is dead, and my strongest attack: Let's do this.) |OFF|OFF|OFF|OFF|OFF|OFF|OFF|OFF|OFF|REDB| Basically, every press of the switch would idealy cause the lifebar to cycle through these phases, after the lowest health, it would cycle back to the beginning, full health status. The actual box will be DC powered, because I want it to be as seamless as possible with no wires showing. The answers that I am looking for : What would be the best controller for this application? Any helpful hints on where I could look for something relatively similar for programming this? I know that I am asking a lot, I am pretty much new to arduino programming and every howto or tutorial I've found talks of controlling all the LEDS together, I'm not sure if that would apply here since I have so many "phases" if you can shed any light on how to approach this, I would be eternally grateful and would totally fight dragons with you any time. Thanks!

Separate speakers different outputs from one computer

Hello everyone. I'm working on a project right now that requires me to send 3 individual tones to 3 individual speakers without any overlap. I had decided that I was going to use the program audacity, as it can generate the tones and frequencies that I need, and a 6 channel amplifier connected to the 3 speakers I'm using. However, after I played around with it, I found that I could only generate 2 tones at a time, and could only get them to play out of the individual speakers I wanted by adjusting the L/R balance on the individual settings for each tone, but I can't create more than 2 without getting overlap. I was wondering if anyone knew if there was a plug-in that would solve the problem that I'm having. Thanks in advance for any and all help.

substituting capacitors

I was designing a board that uses a bunch of the same chip and all of the inputs require a capacitor. For example lets say I have 10 identical chips with identical setups. Instead of having individual capacitors for everything to ground (except for the outputs) can I combine all of the ceramic capacitors and use a couple of bigger electrolyctic capacitors? So lets say I can have 1 capacitor for all of the identical inputs instead of 10 smaller ceramic ones. But for stuff like timing do I need individual capacitors?
