DESPERATE CRY FOR HELP?

Sorry to seem so dramatic but this is probably the 6th time I post on a forum (instructables, adafruit makezine, element14, etc) and havnt found any answers. My TPA6021A4 amplifier I made has alot of distortion that goes away when i touch the positive terminal of the audio input with my finger. the weird thing is, every single (5) audio amplifier ive tried to make so far has had the same problem. the reason I am using the TPA6021A4 chip is because I emailed Ben Heck and that is what he suggested I use, but I cant get it to work. I am making them on breadboards mabey thats the problem? please help.

Plastic Cannon??

Hi, I'm currently in Year 10 and we have been assigned to make a USB lamp. Now, I'm fine with the assignment only I cannot think of how to shape my idea realistically. I wanted to make a cannon shape, with a sphere like bottom before it curves into a thin neck. However, I don't know how to make the plastic bend into the sphere like shape. It's really difficult and I'll include a picture of my idea if it helps!

Beginner in desperate need of help

Hello everyone I only starting using the ardunio two weeks ago and have taught myself to switch leds on and off but thats about it. I came across this 3x3x3 led cube and would love to make it as a mini project for myself. I have searched posts and need help in someone pointing me in the right directions. I have a few questions and I hope somebody can help me as I really would love to make this led cube 1) is there a step by step tutorial on how to make this led cube on a breadboard? 2) Has anyone created a code already that i can use? 3) Can someone show me how to soldier up the leds in the correct way? 4) is it better to do this project on a breadboard or not? 5) can i buy kits that has everything for this project to work? Thanks for reading and hope I get some good advice and help

DESPERATE DAMSEL! LEDs help...

Well, okay... I'm not really desperate but I am in (slight) distress-- needing someone to storm the castle of knowledge to save me from pounding my head against the walls of google-search any longer. Looking for some specific LED information. I have looked through several LED-throw-y Instructables but so far I haven't found the information I need. I am mostly electronics-retarded and so if anyone can give me the correct info I would sincerely appreciate the assistance. I just need to know the batteries/battery power/models needed to power smaller than 10mm LEDs. My project involves a very small space-- 1.8mm-3mm-5mm sized LEDs would probably be best-- I would need to know the kind of batteries I would need (least bulky and least number of batteries I could utilize for each size 1.8mm-3mm-5mm) and how many I would need for each single LED to operate effectively. Also-- is there any real concern of a fire hazard with such LEDs housed in an acrylic/urethane and resin container or would the output of the LED be such that I wouldn't have to have concerns of fire (or melting in the case or urethane/acrylic/resin) ? (Sorry if this question seems dumb, but again I stress how electronics-retarded I really am lol). Furthermore, if the LEDs had vellum or translucent paper covering them to diffuse the light-- would this additionally create any fire-hazard? The housing will probably vary between 14mm-20mm  for the LED with the batteries able to sit outside the LED-housing. I appreciate any assistance in getting the information I need and offer many thanks in advance for any helpful replies!

Tips on storing bikes?

I'm trying to get my patio back. desperately. The problem is, we have threee bikes that take up about 1/3 of our patio space, and we're trying to find a way to reduce the footprint of the bikes, without disassembling them, since one of them is my primary mode of transport, at least one of them has to be accessible at all times. we considered hanging them, but out appartment complex is kinda uptight. anybody have any tips?

Help needed desperately ! (Question related to batteries) Answered

Hi Guys,              Recently I planned on making an portable phone charger the classical way, with a car phone charger. But then I came across the problem of choosing a battery. The 8 AA batteries way is not economical, as I will be charging a Sony Xperia Z1 and it will drain the batteries in one charge. The 8 AA rechargable battery method will be better but will set me back about $20 so that's a no. If I use a 9 volt battery it will charge the phone 20%. The final and the most stupidest method is to connect 10 9v batteries so that I get 9v 4 amps but that will be too bulky. Lithium batteries are useless as I will get the required amperage but the voltage will be too low and the other ones will once again set me back too much. So the only way is to use 8 AA batteries but every phone charge will cost me approx. $1. Is there any other cheap way or 8 AA batteries it is? Thanks in advance :).

HELP, I NEED / desperately want A SUPER BRIGHT FLASHLIGHT for camping / boy-scouts [answered]

Inappropriate Incomplete Spam first thing first, i want absolutely the BRIGHTEST flashlight i can my hands on! how many lumen's should i shoot for (to impress others)? 100, 270, 350, 600, 900, 1500, 3600, 5000+ (5000 Lm i pretty sure is overkill)? i have an led flashlight i got for 12$ and is advertised to be over 600 Lm but I'm pretty sure its maximum is 70Lm. (it seems to be slightly brighter than the 9 LED tactical flashlight i had) but I'm not sure. i have no light meter. the LED itself is (as advertised) is CREE (i don't believe that either but again, I'm not sure).   i would like to make portable HID flashlight. my plans are to: BUY: 6V LANTERN HID KIT (BULBS) HID BALLAST 12V BATTERY (I"m not sure where i could find a suitable 12-15V 35W [or more] battery that will fit nice and snug in the lantern with room for the ballast. the battery should last almost a week with some moderate use.) i think a drill battery would work. i will take the original light out and replace it with the HID. then, i will need to find a place for the slim ballast [but where???] . then,i need to find a battery (i think a 12V drill battery should work [will a 14.4V drill battery with the case off fit in the modified 6V lantern flashlight? if so, where can i buy a affordable and well suited 12V-16V battery?] if there isn't any small, powerful (and preferably cheap), battery in existence? [4 by 4 by 2 array of AA rechargeable batteries seems promising and so does 6^2 by 2 array seem promising. 6 by 6 by 2 AAA] will the ballast and lamp work with less power (6W-34W)? is there a simple and small ballast circuit schematic i can follow? i never found one. so i assume no. :-( also is the 5000K neutral white, warm or cool? (i think it is the closest to neutral white with a VARY slight blueish tint) i think i got a grasb on this and i want 6000K (i want something led white but still bright and useful enough to easly see what i'm doing on campouts)
