Power Supply

With this circuit, does it matter how many amps the input is rated at? The output is supposed to be 2 amps at 9 volts

Amps

Say, I thought I'd ask seeing as I got a little extra money to burn from christmas, anyone got any old/unused car amps they might want to sell to moi? My current sub amp is ever increasingly scaring me and my sub sound's like it's blown a voice coil or something (although I know if it were blown it wouldn't be working as good as it is). What do you got to say Nachomama?

Battery power

I am attempting to calculate my amp need for my garage in order to set up a 12v battery system. Using the formula; Watts / voltage = amps drawn, I have hit a question. If using a 12v battery system and converting to 110v, should I be using 12v or 110v in the formula?Example; 100 watt light bulb / 110 volts = .91 amps. Nice!But if I use the 12v; 100watt light / 12v = 8.3 amps.I'm believing I would be drawing 8.3 amps from the battery to power this light.Plus the converter draw...Please tell me which is correct?

Amps

Can anyone tell me what happens if you take two 1.2v, 1900mAh  rechargeable batteries in parallel connected to an LED?  Does it increase the amount of time the LED will stay on?   I'm new to this.  Working with small solar charging lamps.  Thanks Patty

My Amps! My Amps! *Screams an old crazy man in the deli section*

Yes yes, shhh I want to ask a serious question today. I traded one of my kenwood amps for my parents as their sony surround unit is really shitting out and the sound sounds terrible and the entire control panel on the front is messed up. I just want to know a couple things about the sony to see if I can fix something. The panel, well that's quite interesting to explain and if I posted a video of it you guys would probably think I edited it or something. So imagine this, the bass + and - buttons are beside the treble + and -, two sets of buttons. If you push one of the bass adjustment buttons, it glitches and turns the treble for example, up or down randomly and doesn't do what I wanted it to do. It's like this with all of the buttons and seemed to have happened after we moved here. And I know it didn't get banged around because it was transported in the back seat of a car on blankets to the new house and carefully carried in by me. If I say try to use one of the surround sound adjustment buttons it glitches out and acts like I hit another one that's beside it in any direction. Hard to explain but I'm just damn confused as to why it suddenly happend (dry solder connections?). Damn this post is long and it's only half done...lol. Bad sound, I will not tolerate it under my household, but on the other hand it was a $400 unit back 5 or so years ago and I KNOW it used to sound good, with a such a profound richness of bass that just punched right through you. Now it sounds like shit, the sound is garbled, distorted when turned up, it's not really noticeable until you turn it up fairly loud. I have/had my technics tower speakers hooked up to it and they sounded like shit when I turned them up, yet on my kenwood they sing like the wedding singer days. Any ideas nachomoma? I'll add another note that for most of it's life it's been hooked up to a pair of 250 watt (peak) optimus floor speakers and whenever we played it, it got HORRIBLY hot and warped the top a bit when it was on, enough to push it in and make it spring back up again with quite a force. I liked this receiver a lot and would like to use it again, but I don't know where all these "degradations" came from and despite my useless amount of amp questions/bickering's about I would really appreciate any ideas from you guys. Thanks.. -Punk

Relationship between volts and amps

I'm working on a project found in this thread https://www.instructables.com/community/Solar-powered-cell-phone-charger-case-hack/ I think I'm almost ready to buy parts and start building but I have a small issue with getting the exact voltage and amperage output I need. I've been researching for hours and I can't find a simple answer to this problem. As I understand it, as voltage decreases, amperage increases to compensate and maintain wattage. Working on this basic understanding I've come up with this model. If I have a solar array consisting of 6 PV cells (1.5V 50mA ea) wired together I get 9V and 300mA. This is too much voltage and is on the low end of amps I want. If my math (and understanding of the subject) is correct, then if I use a 5V voltage regulator I will have a final max output of 5V and 433.3 mA which is right about perfect. Am I doing this right or is there more to it, like how I'm wiring the cells together? Am I correct in the idea that using a voltage regulator will increase my amp output? I'm not schooled in electricity in any way so I would appreciate any help I can get on this in as simple of a form as possible. Everything here I've put together from several hours of studying sites on solar DYI and electricity. Thanks. For reference, these are the solar cells I was referring to: http://cgi.ebay.com/High-Efficiency-Solar-Cell-32-22mm-1-5V-50mA-0-075W-/320541888508?cmd=ViewItem&pt;=LH_DefaultDomain_0&hash;=item4aa1c90ffc#ht_2428wt_1148 *EDIT* Below is a diagram of what I suspect may give me a 5V/490mAh output which would be absolutely perfect. I need to know if I can wire two different sizes of solar cells together in this manner and how it will effect the output.

Tiny 12v motor burns out a transformer. Why?

I connected a tiny little motor (12 volts, 60 milliamps) to a 12 volt, 1000 milliamp wall wart transformer.  The motor turned (no load), but when I disconnected it after not more than 10 seconds, I noticed a burnt smell and the transformer no longer has any output.  What happened?  Bad luck, or is there something about a motor's inductive load that would be incompatible with that kind of transformer?

Slightly larger LED project.

Ok, so to start off I have done a few very small led projects before. And for some reason I decided I was going to up the concepts and baptismal by fire. Well to say the least I have a few questions. So all that read and help thanks! The Project:I have included a picture in very horrid crayola color to show you kind of what I am trying for. Essentially I am making a 6ft x 4ft robot head. I have built a frame (the picture) and there is going to be a spandex (or screen depending on what I decide) canvas with the bots head on it. What I want to happen is when I press the button (momentary contact) on the controller it activates the appropriate leds that light up a box. I will have at most 5-6 buttons pressed at once. Simple enough. The squares are going to have 18, 3mm leds. The colors are shown in the pic. I know that different colors require different volt, thus different resisters. The eyes are going to have 2 sets of 18 leds for alternating colors. There will also be 2 outside sets of lights to shine upon the face (18 leds also). "The Questions:"Well other than just asking HOW THE WHAT? I'm going to have this (or at least I want it to be) powered by one source. Maybe a 12v AC adapter. The problem is, is this enough? How many amps do I need to power 218 leds? I guess what I am saying is I know the basics but I need help with the electrical rating part of all this.

Power supply volt/amp question?

Hi, My power supply is ac 110v to dc14V 700ma and I want to connect in parallel 2 strips of 4 led (350ma - 3.2v each)  Total voltage per strip 12.8v with 350ma each. I would like to power these leds at 2.5v each (total 10v)  and at around 250ma each. I installed a buck converter at the output of the power supply to reduce voltage at 10v. Will the amps also drop as voltage is reduced or will it stay at 350ma on each strip?  If it does not drop, how could I reduce amps to about 250-275ma? Thanks

What's up with Amps, voltage and current?

So I'm having trouble finding out where amps come in. Typical batteries (AAA,AA,9v,3v) don't say the output amps, just output voltage. But things like RC batteries, and wall transformers have a specific amperage output. So say my LED and 9v battery. I know I need to use a 150 ohm resistor. Since resistors limit current, then is there still 9v going to my LED its just the amps/current that being lowered before going into the LED? If resistors limit current, or in its unit of measure, amps, then my LED is still getting the supplied voltage just a lowered amperage?  How do I know how many amps my projects are drawing? How will I know if my DC wall transformer with 12vDC and 1 ma isn't going to fry my circuit? How would I know if 1 amp is too much or not enough for any my circuit? Please help, none of this makes sense, ~electricloser

How do I regulate voltage on a multi-amp battery charger.

I know very little about electronics. I have a car battery charger that outputs in 12 voltsDC. It is also "switch" selectible for 2 or 10 or 50 Amps. Once I select one of these choices 2/10/50, I would like to vary the voltage up and down from 1v to 12v. How do I build something that will vary the voltage at each of these amperage levels. Thanks- Steve

Help wiring an LED array

I'd like to buy some LEDs off ebay and build some LED arrays but I'm confused as to how to wire it. For example, lets say I have 100 watts of LEDs (aka 1 watt x 100 LEDs or 10 watts x 10 LEDs) as an extreme example and each LED has a max voltage of 12 volts. Then lets say I have a power supply that provides 100 watts at 12 volts. How would I wire it? I'm worried that if I hook it up, lots of LEDs will just burn out. Just help me understand what I need to watch out for here. I'm obviously a super novice. Have pity.

How do I start my Arduino going?

Hey guys I just got my Arduino Uno and I'm not exactly sure how to power it up using the jack. I now know that I can run it off of the USB cable but how do I hook a battery to it? I've heard that your supposed to use 5 volts, but I don't see how I can get 5 volts. I only use AA and 3v and 9v batteries. So, also, since it can run off a USB port, I'm assuming I can use my phone charger to hook up the USB to it? Isn't it all 5.1 v? Well, please help me out and tell me if how many volts mA the board needs, which is too much and which is to low.  Thanks guys!!! ~electricloser

Float Your Boat Challenge

<br /> [BCITSA YouTube Chanel] Recently, the BCIT Student Association (BCITSA) hosted a 2-day 'Float Your Boat' competition for the Marine Engineering Students at the Marine Campus in North Vancouver. Contestants were supplied with ‘surprise’ materials to construct their vessels with; materials included plastic garbage bags, popsicle sticks, bamboo skewers, aluminum foil, string, plastic party cups and tape. Teams of 2-3 were given an hour to become acquainted with the surprise materials, then design and construct a sea-worthy vessel. Boats were then raced in heats on the indoor pool, using human-powered fans for wind, to determine who had the fastest time. Prizes were awarded for: Fastest Boat, Most Creative Team and Best Overall Design, all donated by local businesses. I attended just to check out the scene, but the event was also covered by local news media and has since been broadcast on stations in Metro Vancouver, as well as printed publications. Pretty awesome for a low-budget student association! And there's more, the BCITSA has a history of hosting awesome events for students, such as: 3rd Annual Flying Extravaganza, where students at the Aerospace Campus in Richmond, BC "construct planes from everyday office supplies, with the winners chosen based on the distance they can safely land their lego pilots. Additional prizes go to those with best design and best crash." CTV News coverage (youtube video) Engineering Week, hosted at the BCIT Main Campus in Burnaby, BC, where electronic, mechanical and civil engineers compete in tower building, catapult destruction and racing CO2 powered cars, all made from everyday office supplies. As well as the competition Engineering Students brought along projects they have been working on to share with their fellow students, there was even a real live Angry Birds game being played. CityTV News coverage (youtube video) Facebook photos Aside from a much needed break from studies, challenges like these put on by the BCITSA pushes students use creative solutions learned in class with hands-on problem solving, turning academics into tangible results.

What amp would fit these speakers?

I'm looking to buy an amp to hook some speakers up to but I don't know the specifics of what I should be looking for. I'd like to get it from a store and know what to get ahead of time. The speakers are two combo woofers/tweeters and rated at 200w peak power and 4ohms. How many watts should the amp be? The amp needs to take bare red/black water, have a 3.5mm line in, and plug into the wall. This isn't going to be part of a big home theater system, just a little unit so what would be a good cost of a low end amp? Thanks for the help.

LED Questions

Help, I'm afflicted with inspiration in quantities that exceed my skills!So I came up with an idea for a project that would probably require the use of LEDs, which I know next to nothing about. Ah, said I, the Internet can teach me much... so I turned here and found the (nearly) perfect Instructable, "LEDs for Beginners":https://www.instructables.com/id/LEDs-for-Beginners/Having read this most helpful I'ble, I certainly came away more knowledge than I'd previously had, but still not enough to properly plan my project.Basically, I'd like to create a 2D "array" of LEDs to use as a light source, in order to backlight a roughly 8.5" x 11" translucent panel.It seems like it would be straightforward to just wire up a bunch of white LEDs in series to a power source and a resistor, and be done. I'm not afraid of a little trial-and-error, but I prefer to know at least roughly what I'm doing going in, so I'm asking for your help. Here are my lingering questions:1. Should I wire my LEDs in series, or in parallel? (Or some combination thereof)? In series, I gather that one LED failing will break the whole circuit, which could be a pain. On the other hand, I've seen several projects and sites that cryptically recommend against wiring these in parallel.2. Are there pre-built strips of LEDs I could acquire that would make this project simpler?3. If I want to vary the brightness of my light source, can I use a variable resistor (potentiometer), or does the nature of the LEDs preclude the use of this type of dimmer switch? If so, could I vary the brightness with multiple switched circuits, turning off half the LEDs for half brightness, 3/4 off for quarter-brightness, etc?4. I've got a slew of transformers from old tape decks, telephones, cell phone chargers, etc. Can I appropriate one of these as my DC power supply?5. How do I gauge how many LEDs I'll need, and what density is best to lay them out? I'm looking to create even, diffuse light, with no noticible bright/dark spots.6. Do I need to worry about heat?7. Are LEDs even the correct way to go here? Should I consider fluorescent light instead?I realize these are a lot of questions, but if you're an expert on LED projects, you could save me a lot of research time. If (I build this gadget, it will definitely show up here as its own Instructable.)Thanks!-JD
