Choosing IC

I recently came up with the brilliant idea (read: scheme) of constructing gloves with built in  RGB LEDs that fade through colors randomly. I plan to sell these to ravers as they are usually spoiled rich kids (no offense) and I can fund my new found interest in electronics. My question is if anyone knows of any ICs that can control this without having to program it, like the LM3914 can work as a VU meter. If no such thing exists, then the cheapest alternative.

Choosing a relay?

I was about to make a project, I was all set then I realized that I hadn't chosen a relay yet. (Circuit http://2.bp.blogspot.com/-IdzxyPF4WYE/UfBCWb0deoI/AAAAAAAADZs/1-eYB2ufQCA/s1600/Clap+Switch.jpg) As I didn't know anything about relays or AC voltage I started studying. At the end I came to this. As I will be controlling lamps with either incandescent bulbs or led bulbs and phone chargers a 5v, 220v 1a relay will be enough, since Bulb 0.27 A, LED 100 MiliAmps and Phone Charger a few watts. So the question is that are my calculations right and what else should I know about relays e.g operating voltage resistance and other stuff. Oh and is there a 0.5a relay and if there is will that be enough? Thanks in advance. -Prickly Potato

"The 'Ible Awards"

Ok, i got this idea whilst in the chat room. The Instructables Staff, should look out throughout the month for outstanding behavior shown by members of the community, and at the end of the month they choose someone to be the "-Ible member of the month" or have at the end of the year "The -Ible Awards" with multiple categories and the community votes on a winner, and they receive like a trophy or a badge. Just throwing it out there, feel free to comment/debate.this goes along with Keith-kid's idea from about a month ago (which he pointed out to me):https://www.instructables.com/community/Idea--Instructables-Awards/This idea was mostly a group thought, so credit goes to myself, Keith-Kid, Killerjackalope, and Adrian Monk

Choosing the Right Amplifier?

Halo everyone again! This time around, I am planning to build a dedicated modern jukebox/ music kiosk. It will have touchscreen and all the good stuff. HOWEVER, I am not sure of the what amp to use for the speakers. I am planning to drive 6 coaxial speakers on this thing, 3 for each channel. The coaxes have a spec of 35watt continuous and 140watt peak. First off, will 6 of these be powerful enough to get a large living room thumping for parties, and if yes, what power amp would i need? I am planning ot buy the Sure Electronics amp boards, but ont know if i should get the 2 channel 100watt or invest in the 2 channel 300watt. These coaxes are 4ohms each, and i will probably hook them up in series. (unless there's a better way you guys can recommend). Would appreciate any and all help!

Choosing the right zener diode? Answered

Hi Guys, I want to make a power bank kind of thing that can charge my laptop. Its not at all efficient and a powerbank or rechargable batteries would be better but its a challenge kinda thing.

I have attached a picture of the schematics. Please don't comment saying that its not efficient and stuff, I know that.

Choosing an Arduino compatible board

Hey everyone. I'm very new to microcontrollers. I've never dealt with them but I do know how to program. I'm interested in creating a wall-avoiding RC truck on a tight budget.

Choosing paint ball gun

When choosing a paint ball gun you need to first look at your budget. how much are you willing to pay. remember you also need a tank ($20 to $300) and a hopper ($5-$150) and a mask ($30 to $200)you you want a cheap gun to shoot in you back yard and do not need reliability accuracy or quality Get a spader if you want to play paint ball don't get a spyder. The first guns you will probably look at will be Tippmanns, they are extremely durable and reliable. How ever you can not play speed ball with a tippmannn your limited to woods ball. The only real reason to get a tippman is the flat line barrel system.There is no reason why you cant get an electro-pneumatic gun and play woods ball. A proto slg or pmr weighs 3-8 pounds less than a tippmann. Woods ball games last for 30+ min a person with a 1.5pound gun a 2 pound tank and a half pound hopper is going to Own over a person with a 5 pound gun a 4 pound tank a half pound hopper. elect-pneumatic guns are lighter and are multi-purpose a with a tippmann you can only play woodsballSo which gun should i getfor a cheap woodsball gun get a Tippmann 98 custom pro or a tippmann A5For a great multi roll gun look into a Proto Matrix rail (pmr) or Proto slg (super light gun) at my local store the pmr cost $10 more than the slg ($250) but it comes with a locking feed neck (worth $20+ and older more reliable internals) For a little bit more performance at a higher price the invert mini is a great little unique gun its not the most reliable but you get a great gun for $350BTW never buy smart parts guns. I think the best gun for mid level players is the Dangerous power threshold $500 its sweetwhat i originally said I have been playing paintball casually for 3 years or so, and i dont have my own gun (iv been using my friends 98custom). I want a relatively cheap C02 marker with no complicated stuff (I.E electronic triggers) The Tippmann A5 seems perfect to me (cheap, High Bps, accurate, plenty of upgrades). If you have one i would love to here about its pros/cons or if you have something thats better for $150-250 let me know. or if you know any good reliable paint/have any upgrades (im looking at a longer barrel and a response trigger) please let me know.Some vids from Mike (thanks love your channel)The woods ball/tornament The tippmann show slg review pmr review Invert Mini review tanks gear bag

Head to Head Contest: You Choose.

Whoever creates the better Instructable (higher quality, cooler, featured, most voted for, etc) will win a patch similar to the images below. Because this is the first run, and I can't think of a subject, the competing members will have to agree on a subject of their choosing. If there is a flood of volunteers, the community will vote on who they want to see face off. In this trial, I will allow up to four separate pairs to compete. If this doesn't make any sense, well, I just woke up! :PThe stats are as follows:Lithium Rain VS. gmjhowe: Card, any kind of card, and it has to plug into a computer. Deadline: to be determined.

I am building a circuit in which a photoresistor triggers a relay which then powers a motor.

This is the relay I am thinking of: http://search.digikey.com/us/en/products/TXS2-L-12V/255-1898-ND/650137 . I am pretty sure it's the right one, but I wanted to make sure.

Help choosing AC Power Adapter

I found one at www.goldmine-elec-products.com, that's 3VDC 350ma, would this one work? I have no idea what the 350ma represents so I'm at a stand still on this. Also, would I have to match these specifications, (3.3V 2.0A), exactly? Or could this vary somewhat? Any help would be appreciated!!

Choosing the right LED Dimmable Driver...

Hi all, I am hoping someone can clear this up for me. I am building a DIY LED aquarium light and have chosen the following components: - 16 x 3W LED, Cool White - 4 x 3W LED, Royal Blue - 2 x 3W LED, Red I want to run all the LEDs off one dimmable LED driver and I have found this one which I think will work: http://www.aliexpress.com/item/Free-Shipping-Top-selling-12V-0-10V-dimming-LED-driver-PWM-led-dimmer-constant-voltage-3/1410890719.html I also wish to make each colour dimmable by using a potentiometer for each of the 1-10V lines. Therefore, 16 white LEDs will be in series on one channel, 4 blue on the second channel and 2 red on the third channel. What I would like to know is the following: 1) Will I be able to safely run all the LEDs on each channel as described above? 2) What value potentiometer should I use for each of the 1-10V control lines? 3) Do the 1-10v control lines require a seperate power supply or are they regulated internally from the 12-24V DC IN? Any help/advice is greatly appreciated!

IDEA: Choose what shows in the activity feed

I just thought of an idea for making the activity feed a bit less of a mess. Instead of showing a member's activity and other members' activities on the member's page, why not have an option for sorting it? See the image. A.O.H.I. - Activity on his Instructables. I just didn't have enough space... I think there should be options for Most Recent, His Activity, & The Activity on his Instructables. This is somehow similar to the way that here, we can sort I'bles through Recent, Popular, & Most viewed. Recent should probably be the default.
