I thought it would be fun to see everyone's pictures of their white Christmas. We have been in a drought so the snow is very much welcomed. It only snows a few inches a year here and usually melts the next day. I think this snow is going to stick around for a couple of days. If you don't have snow pictures to share, post a picture of Christmas lights or a video. I found this link with thousands of lights. http://news.yahoo.com/vitality/ .Keep warm and have a splendorous day! Sunshiine

I recently bought a Pyramid PTA150 1500 watt power amp, and its clipping led's always seem to be lit when my mixer is set to half volume or higher, even when the amp is unplugged. Could they be powered from the input voltage when it is high enough? Is it bad to push my amp when they are lit? and it has a high volume cooling fan so I dont think it will overheat when pushed.?

After trail and error i have made a joule thief with the following: 2n3409 transistor, 1k ohm resistor, led, and an air coil. what would i need in order to boost the power up to say 100v or more? the cheaper the parts the better, at least for now. I've read some what about micro controllers and using 2 555 times, but i am unable to use anything that requires a computer. everything needs to be simple enough to be used via a bread board. I am desiring high enough frequencies and voltage to jump a small spark gap. i am aware the spark is waste, but that is the point.

G'day All, If this has been done before, I apologise, but I have not found anything when I have searched. I am a team manager for a team of students who need to design, construct a three wheeled vehicle. The test is a 24 hour "trial" (more like a race ;-) ) We have been competing in a category for "Hybrid Vehicles" which an additional power source to asssist the rider. In our case it is a 50cc engine using a friction drive arrangement so we can disengage it if required or if we desire. The reason for this is that we only recieve 3 litres of petrol for the event............ This is my problem. I have not been able to measure petrol in the tank accurately enough. Over the last two years I have had one litre left or ran out after 21 hours. I have been thinking of using a strain gauge or load cell to measure the weight of the tank. I'm thinking it could be as simple as powering up the load cell with the appropriate voltage, and measuring voltage drop across it, maybe with an added resistor. Or it could be made more complex by using a circuit to drive a number of LED's giving an indication of the fuel in the tank. If anyone outhere has any ideas to do this simply and reliably, I would love to hear from you. If it is more complex then so be it. Here is a link to the event to give you an idea of what it is about http://racvenergybreakthrough.net

It used to be that patches were issued for entering or winning weekly contests, and that was a nice thing. I like looking at someone's profile and seeing the patches they've received. Other than the Chopsticks challenge, though, I haven't seen that appear on any of my entries. Also, it would be great if there were some indication (banner?) on winners of weekly challenges. Is that possible? I realize you guys are really busy, but these would be nice.

Hi Folks. I was chosen as an alternative winner for the camera & photo skills challenge & received my printer a few days ago. My problem is that the printer I received is a US specification one meaning it is set up for 120v & in the UK we use 240v; I have been trying to find a 240v to 120v step down converter for it but so far have had no luck as I need one with a functioning earth & the only ones I have found are not suitable as most of them do not have a proper earth pin available, the few that do have an earth are far beyond my current available budget. I have tried EBay to no avail likewise Maplin, eBuyer & PC World; does anyone know somewhere in the UK that I can purchase a suitable one that does not cost the earth? (Pardon the pun) Thanks in advance for your help folks. Seasons Greetings to you all. Nostalgic Guy.

I'm looking to try to drive a VGA monitor using a PIC 16F690, on a 12MHz clock (3,000,000 operations per second) The most accurate the signal from the PIC can be is 1/3 uS, but the timings given are to 1/100 uS for the 640 X 480 @ 60Hz standard. Overall, each frame does come out to a whole number of cycles, so does the exact duration of each line matter? I've seen a PIC output very basic graphics on a 4MHz clock, so I would expect it to be fairly simple to just light up the display on 12MHz. Alternatively, is the display smart enough to fit whatever is fed into it onto the screen? Thanks for the help.

I have started to try and create a motorized flip up license plate. It's mainly for my motorcycle. In the "off" position the license plate is down and readable. Turn the switch to "on" and it flips up, making the plate unreadable. I thought about using a servo or a motor with limit switches. I do not really know how to wire something up to control the servo or motor. Any help would be great. I know they sell these as kits, but they start off at teh $150 dollar range. Thanks in advance!

I just purchased a set of electric running boards for my truck. i have to make my own wiring harness. the problem i have is, i need to wire a relay to each running board. i need the relay to power the motor down when the door is opened and is triggered by the door ajar switch which isnt to hard to do. the hard part is to have the relay reverse polarity so that the motor retracts the running boards when the door is shut and the signal is lost from the ajar switch

Ok so the Beagle Board can run Windows Compact, and Linux and stuff right? Well I've been looking up descriptions for the Beagle Bone, and I'm not sure if it can do the same thing. I want to make a wrist-computer thing, but the Beagle Board is to big and a bit on the expensive side. The Beagle Bone would be an ideal replacement, but I'm not sure if I have the same capabilities as I do the Beagle Board. Can someone tell me if the Beagle Bone can run Windows Compact or a small OS like Linux?

I bought a RC submarine that was running at 40Mhz. Submarine broke, seller shipped a replacement, but replacement could not be remotely controlled by original remote. In fact, while looking under the submarine, there was a sticker written "49Mhz - 3". I guess it is referring to Channel 3 - 49.860Mhz. So could I buy a 49.860 crystal, remove the 40Mhz crystal from remote controller, and get my submarine to run again? Is there anything else to consider???

Hello, I recently went to a Camera supply store and fell in love with this amazing light.. Its a Fotodiox LED 1000 ASV, you can google it or look on fotodiox.com to get a better idea of what I'm trying to accomplish I would like to make one.. so far I have this is mind.. I can buy a lot of about 1000 LED's for really cheap.. Mirror plexiglass maybe about a 12inx12in to mount all the LEDs and a potentiometer to dim. I would like to run on 12 volt simply because it gives it more power options for my needs, the one thing I'm kind of confused on is, Am I really gonna have to wire 1000 Resistors to make each LED 12v? Or is there a simpler method.. Also, power supply is an issue, I am not sure if I can just wire all the LEDs down to two wire for a regular 110-220V Input, 12v Output adapter.. Do I need an LED driver of some sort? Especially If I want to be able to dim. Building the Housing and stand shouldnt be an issue, Its more the electrical part where I am concerning myself with. I'm pretty mechanically inclined, I do automotive 12v as a profession and hobby, I'm just recently getting into "higher voltage"=D "I'M READY TO STICK A FORK IN A SOCKET!!" lol, can anybody give me any tips? details? or even how they would go about doing this? Any advice is better then no advice.. and any direction is better then starting lost, Thanks in advance! I Will start making an instructable soon once I get my supplies in (LED's, Mirror Plexi) Considering that where I have to start.

Hello I just recently came across this site and just from browsing a short while i can see this is the place i need to be. I currently have a desk lamp design im in the process of making. Yet i need a light source. I know you can go buy a normal light fixture power cable with socket attached. but i need LEDS. im working with an area about the size of an altoid case that fits inside of a slotted wood piece. I need to find a cheap way to make this. I have seen many led tutorials but have not found anything yet on wiring for plug in ac power source and connecting it to LEDS. Im not sure if there are different resistors or any extra needed pieces that i am unaware of. my skills are fairly basic with leds, yet i can easily follow good directions and adhere to what is needed. Any help would be great. Thank You

I just purchased a set of running boards off of a 2011 f150. they are electronic and i need to wire them up to a set of relays. what i am trying to do is to make it so that when the door is open it triggers the relay and powers the motors causing the running boards to open up, easy enough. but the problem i am running into is that when the door is closed and the door ajar switch is no longer sending a signal, i need the relay to then reverse the polarity so that the motor will then spin the opposite direction causing the running boards to fold back up. the motors on the running boards do have built in stops so i dont have to worry about leaving power to them. i am also finding out if the door ajar switch on my 2004 chevy silverado uses a positve trigger or a ground trigger. any help i can get would be much appriciated. thanks
