I recently purchased a normal set of white LED christmas lights for my apartment. But recently I saw similar units that run on solar energy. I was wondering if there was a way to convert the sets that I have into either battery powered or solar powered.

Hello, I wonder if anyone knows how I might go about adding power to passive speakers without plugging them into an amplifier, so that I can have them work with my PC?

So I figured out a really good option for my external rumble pack I want to make, I see these Wii lightguns use X2 AAA batteries and have a micro switch that engages the internal rumble motor on the handle of the gun. The batteries are connected to a microswitch and the switch is pressed after the trigger is physically pulled. How can I convert the AAA batteries power method into an external 12V power connector for continuous use and stronger motor vibrations etc? Like I said this is my first DIY thing. I want the AAA battery method to be converted to a stronger more capable 12V. I plan on buying some strong force feedback motors that need 12V. Eventually adding a small Solenoid too.

In a web search looking for 12v Christmas lights to run off my small solar system, I found this; http://www.fly.net/~thundt/xmas12v.htm This looks very straight forward and easy enough to do.Has anyone here tried this?I bought a small set of solar powered at Target ($14.95). Way under powered and last only a few hours. It's going back today!This looks like a way to get brighter, longer lasting lights and I don't have to run my converter. My 160 AH battery should power it up nicely, I would think...Think I found a project for this afternoon!

Hello, I want to connect a portable solar powered rechargeable to 2 DC fans of 12v to cool my car. 1. I have 2 options of portable solar powered: (A) 1500mAh, outputs: 5.5V / 800mA (B) 2000mAh, outputs: 5V 500mA which one is preffered to connect to those PC fans? 2. most of the PC fans are working at 12v. I don't quite sure if I'll build simple 5v to 12v regulator it will works and produce enough airflow. Thanks.

Hi, At work I have an ultrasonic testing instrument that displays the signal on an LCD (640x480). I also have a HUD (head mounted display) that requires a HDMI input. The only way I can think of getting the 2 working is to put a camera over the display and send that to the HUD. Would anyone know of a way to connect something to the LCD ribbon directly and convert it to HDMI? Many thanks for any help provided.

Has anbody else used sites like hulu.com(only for USA, sorry Europe) and TV.com and other sites like that to watch free tv? Because i just got rid of the dial-up at my house and got a 1mbs DSL conncetion and am starting to watch TV online, being that i still recieve free over the air TV and with the interent i can watch all sorts of amazing shows like mythbusters and how its made(and occasionally the office). And after watching all of those shows online, and for free I was wondering if anyone knows of any decent converters/downloaders(you know just a regular flv. downloader) for me to get these on to my iPod, because that would be awesome to be able to watch all sorts of tv shows on my iPod, legally. So post some other sites that you use to watch TV and converters/downloaders you use.

I have a heating pad (Sunbeam, the kind of pad used for muscle aches etc.) that plugs into the wall (110v AC). It says on the pad that it draws 42watts. For various reasons, I'd like to have the heat generated by a DC source rather than AC.I'm thinking maybe there is a way for me to plug some kind of converter into the wall (AC to DC) and then plug the heating pad into this which will still result in heat. I have no idea if this is possible. The pad has a switch for three different heat settings.Can I do this? How?Thanks for any suggestions!

Having purchased an android tablet with mini USB ports I have finally got my tiny USB bluetooth dongle to work with it using the provided OTG USB to mini USB cable. I was wondering if anyone has dismantled a bluetooth dongle and fitted it with a mini USB connector? I think it would be so much better to have it sitting directly flush to the tablet rather than having it hanging out at the end of a cable. Would this be easy to do or should I leave well alone? Thanks Gaz.

Looking to make some stuff but don't really have access to a workshop. Not so much of a problem tool wise, all I really need as a drill and a hacksaw, but will definitely be needing a medium size bench vice. Don't have one, can't afford one. So was thinking to somehow convert one or two G clamps or something similar. Was wondering if there's any existing resources or tutorials on how to do this, just so I don't unnecessarily reinvent any wheels. ta.

I have a device that runs on ac (110-120 Vac - 180w). I want to make it portable so that it can run off a battery pack such as AA or 9 Volt or even a custom battery. Is this too much of a power requirement to make it possible??? thanks in advance for your help.

Hi there, Can anyone give me some tutorial on how to convert AC power to DC Power? Basically I have a transformer step down the AC voltage from 230V to 13.4V on 50Hz. In order for me to be able connect LED light directly to the wall, first of all I need to convert the AC Power to DC Power. To be honest I am a noob when come to electronic part especially the calculation section so please go easy on me. What I have done so far is getting a rectifier and transistor. I tested the rectifier at first, it convert AC to DC power successfully but somehow my voltage drop by 1.7 Volt. I end up getting 11.7V. I notice that the voltage goes up and down from 11.73V - 11.79V. Then I add a transistor with 16V and 100UF to smooth the wave. When I checked my voltage goes up to 18.32V - 18.37V. Due to lack of knowledge, apparently I got myself a wrong transistor. After googling for a while I found the formula but cant figure out how to use them. After asking around apparently I need more than just rectifier and transistor to keep the LED last longer plus the AC Power with 50hz will make the LED flickering. I need help in building a complete 13.4V AC power to 12V converter plus a power constant current source. Thanks in advance.

I've searched for weeks for an answer that doesn't require a PhD in electrical engineering and hope someone here can help. I have a motion activated Halloween prop (walk by and it talks, etc) however, it requires quite a bit of light in order to detect the motion. I'd like to either put it on a timer and/or just let it chatter randomly so that it will actually be useful. I love the phrases he uses more than the prop itself and plan to remove it's electronics to place in a different prop. However, it's pointless if it remains quiet as we won't have him close enough to a bright light source to make him talk. Help? Thanks Elaine

I would like to know if I can use this particular charger to charge my skil batteries. The problem I have with the manufacture’s charger is that there is no automatic shut off or protection from trying to charge a bad battery. When you charge the battery for to long or try and charge a bad battery the manufacture’s charger burns out the chargers transformer. My goal is to have a charger that I can just put the batteries in and forget about them until the next time I need them and then grab them out of the charger and have them ready to go. I can disassemble the manufacture’s charger for these batteries and easily remove all of the guts. Then could I just wire the ends of the Alpha charger to the ends of the manufacture’s charger? What do you think? Will this work?

Maybe it could still run DS games. Does anyone think this is possible? Can you explain how? And what do you think its capabillities would be?

I need to reduce cords on my device, as much as possible, for a project I am working on. I really would like to convert this device from wired to wireless. First I will explain the images, then the 2 ideas I have.First image "before" = A device with a long headphone cord.Second image "after" = Idea of solution #1.Third image "better" = Idea of better solution #2.---Idea #1 - The less-preferred method.For this idea, I'll need to cut the cord with a pair of scissors and rewire the ends to eliminate the excess cord, to achieve the results in the middle image. So How do I go about doing this? And is there a better way?---OR---Idea #2 - The more preferred, long-term method.Observe the third image (idea #2). Is there any way possible on this earth to achieve this? I think it is absolutely crazy that I cannot find this kind of device anywhere on the market yet, in our day of technology.Thanks for your comments!

Hi everyone. The Dialpad from an emergency outdoor phone was being thrown out in the trash and I thought I could do something cool with it so I rescued it. But I was wondering if anyone knows how to make it into a usb device (like those small numpad attachments you can buy) I don't know much about these kind of topics, so any and all help is greatly appreciated. The model number is Ceeco 700-100 rev3. I would attach a picture of it but I accidentally left my phone at work. So instead here is a picture of one that looks like it. It looks almost exactly like this http://i01.i.aliimg.com/img/pb/418/173/607/607173418_606.jpg and has 8 different color wires coming out the back Thanks in advance Jwag

Wife owns a very expensive piece of Japanese cosmetic device that uses a very special Li-ion battery pack but the battery died! No way I can find a replacement for the battery pack. The battery pack available only has 2 wires (black and red) but not 3 wires (the yellow wire). I am afraid if I get a 2-wire battery pack, it won't work at all. There are lipo battery packs, but I don't think I can replace li-ion with lipo battery packs?! I am wondering how to convert it to an AC power? I have no experience doing this at all, so if you can provide as many details as possible, that will be great! The battery pack: 3 wires connected to the connector: red, black and yellow; 7.4V, 750mAh The AC adapter used for recharging the device: INPUT: 100VAC 50/60 Hz 8VA OUTPUT: 9VDC 500mA Thanks a lot!

Hi. I have a Boss DS-2 distortion pedal, but my problem is, it drains the 9 volt batteries like a semi-trailer. So I basically wanted to convert it to AA batteries. Technically speaking, I'll need 6 AA's to make 9volts, but 9 volt batteries have a different current don't they, or will that not matter in this application. I'd also like to insert an on/off switch because it drives me crazy that the only way to remove it, is by pulling out the 'input' cord (guitar to pedal). Please respond if you know the answer.

Hello Everyone, I was wondering if anyone can help me with a simple solution to my problem, I was to be able to get the sounds from my guitar into my ardunio and have the correct frequency be stored. I can get the guitar connected to the arduino and numbers come out of the serial monitor but they don't make sense, i need to have the correct frequency come up for each note i play, I have looked at a few solutions but being a beginner to this some go over my head or they just didn't work. Can anyone help me or point me in the right direction to be able to do this? Thanks P

So i, like many others, have some strange obsession with Hidden Blades and really want one. However, i do not have the machines to make one from scratch like most of the walk thoughs on here, and since i do not have enough time at the moment, heres what i was wondering: Is there anyone out there with enough time, money, brains and skill to convert a shop bought hidden blade from spring loaded mechanism to the more realistic ring pull mechanism? I think it could potentially be quite a challenge, working around the already existing parts. I am talking about the blades on sites such as Forbidden Planet, and also i have found iconiccollectables.com selling them.

Recently I bought a Blender imported from US(to India) which runs on 120V 60Hz. I need a converter which Converts 240V 50Hz to 120V 60Hz. I got an idea of using a rectifier-inverter circuit such that by varying the gate signal can accomplish the aim. Is this idea a possible one?

I want to convert the 2.4 GHz from a WiFi transmitter to one fourth or 600Hz which is in the newly freed up white space area for greater range. Anyone know where to find schematics for this, or make schematics? Is the circuit complicated? Thanks

Yes, you read that right-people at home are converting their regular gas powered cars to electric. They have an average range of 40 miles, which could be doable if you have a short commute or live in town.Of course, since they are charging them by plugging them into a regular outlet, they aren't really being all that green. You'd have to charge it off solar or wind power to do that. But it's still saving all those nasty car emissions-and it's very cool.So when do we see an instructable?http://www.cnn.com/2008/TECH/ptech/08/14/electric.cars/index.html?eref=rss_topstories
