I am using a micro controller to switch a transistor which will then switch on a relay. I have heard that you need a resistor in between the output pin and the base of the transistor. Why is this and how do you calculate what size. Also the micro controller is running off a 12 battery which is regulated down to 5 volts for the controller. Can a transistor use a 5 volt source to active the base and then have 12 volts running through it activating the coil on the relay. I apologise for my poor electronics knowledge.

I'm going to attempt to make a super micro tesla coil that is 100% contained (unless it runs off of like 12 volts dc, then I'll use a wallwart). Of course, one of the i biggest problem is the power supply. So this is what I'm asking, what's the best way of ramping up the voltage? A tiny toroid transformer? An inductor that gets pulsed? Voltage Multiplier? Something with static electricity? Some type of Inverter? Using Greinacher Cascades? A marx generator hybrid? Other stuff I havn't heard of?

I am looking at hooking up an old photo eye from a garage door to a micro. The end use will be in a device to detect if my dog is about to jump over the fence and take a picture as well as play some audio of me telling him to get down. The problem is that I don't know the correct way to connect the photo eye to the micro. I believe the transmitter site should be powered with 12V, but I would rather know for sure before frying the sensor. My garage door opener doesn't have a port for the photo eyes, so I can't check the outputs on it, but I was hoping someone here might already know, or might investigate their own open. Thanks for any help.

Some of the usb micro cables i have for my solar cell battery don't work, but when i plug in the usb female adapter and use the usb cable i use for my computer, my droid x charges just fine. being the way i am, i had to know what was going on, so i got an old bluetooth headset and desoldered the female usb micro plug and put some leads on it. then i plugged the cables in and tested continuity and i found out that the cable that works had pin 4 connected to pin 5, but the one that didn't work had no internal connections at all. i find the position the cable sticks out when it's plugged in kind of annoying, so i might be able to kill 2 birds with one stone by making a small extender with pins 4 and 5 connected and just leaving the extender connected all the time or would my dx detect that pin 4 and 5 are connected without a voltage and cause problems? i would really like to just make this, plug it in, and not have to worry about cables not working or getting in the way, but i don't want to test this on my $600 device when i don't know what might go wrong.

Hiya guys is there anyone that can guide me to finding an instructable that deals with interaction in remote places using a micro-controller. For instance people in 2 different locations in the world, want to engage or enhance social bond or interaction by using a motion or proximity sensor and internet of things for instance triggering a sound or an led light that can be sensed in a remote location. So one location motion is detected and the other location this detection can also be seen, if that makes sense? For instance similar to this kind of project http://goodnightlamp.com/ Could this be done? Thanks

I have four different colored flexible LED strips on the bottom of my copter. Presently, my only option is on or off. I would like to make them flash or do something different. On each LED strip there are 9 lights and also resistors. These are the type of led strips that can be cut if necessary. I know I could go and buy a micro controller but I'd like to try and make something if it's simple and not to expensive. The power will come from onboard lipo battery. Any thoughts or suggestions are greatly appreciated. Thanks in advance, Darrel

Hello ... I would like to kindly ask anyone, that is good in electronics for help. I add 3 pictures of the SPY PEN and my questions are about the small camera(JH 70-B). I would like to make this camera to make VIDEO via a cable (not to write it on memory) ... but just by a (RCA) cable so I can use any recorder I would like. I have a few questions, that are bothering my mind and I can't help my self :( 1. would the camera be able to give video signal by it self or does it need some part of the PCB board ??? ... (I mean ... if I would give + and - to some of those pins ... and find one pin, that would give the video signal) 2. If I need the part of the PCB board ... could you show me, where would be the VIDEO signal ??? And where would be +/- ??? In my (totally amateur) opinion, I think, I will need a part of the PCB ... but I don't know, which of all these components are part of the "camera"to give video signal. Thanks for any advise ... zholy

I took apart an old air conditioner for the turbine blades and the second motor is from the air conditioner. The DC motor is from a salvage shop, I don't know any more about it except it was made in Canada. I am a long time out of school and not very handy so please don't suggest I wire my own alternator/generator. I know I am ignorant, but I hope you will keep answering my questions until I build the dang thing. Thanks John S.

Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don't scale down well -- there's too much friction in the gearbox and other components. "With rotary power, there's nothing out there that generates under 50 watts,"Â Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington's Tacoma Narrows Bridge (aka Galloping Gertie).Frayne's device, which he calls a Windbelt, is a taut membrane fitted with a pair of magnets that oscillate between metal coils. Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines. Frayne envisions the Windbelt costing a few dollars and replacing kerosene lamps in Haitian homes. "Kerosene is smoky and it's a fire hazard,"Â says Peter Haas, founder of the Appropriate Infrastructure Development Group, which helps people in developing countries to get environmentally sound access to clean water, sanitation and energy. "If Shawn's innovation breaks, locals can fix it. If a solar panel breaks, the family is out a panel."'Frayne hopes to help fund third-world distribution of his Windbelt with revenue from first-world applications -- such as replacing the batteries used to power temperature and humidity sensors in buildings. "ÂThere's not a huge amount of innovation being done for people making $2 to $4 per day,"Â Haas says. "Shawn's work is definitely needed.Â'http://www.popularmechanics.com/technology/industry/4224763.html?series=37

So I get the general feeling that micro knex are the bane of a knexer's existence. But I was thinking the other day, why couldn't a gun be built with micro knex? As far as I can tell (I don't actually own any) they are the same as regular knex, only smaller. If one amassed enough micro knex, couldn't one theoretically build a fully functioning knex gun in the miniature? I just thought that would be kind of cool to have. Thoughts?

The title says it all! I'm looking for a small enough unit to carry (under five pounds, optimally), that can either heat or cool any liquids passing through it. I was initially considering cooling plates, but that requires an extra pump and more equipment, which kind of brings me over my weight total. It's also perfectly fine if both units are separate, as long as I manage to get my hands on something I can use. Thanks!

People and micro-aircraft race to rescue 'hostages'Robots inspired by moths, locusts, flies and swifts will take to the sky this week in an international competition for micro aerial vehicles in Agra, India. Teams will vie for the title -- as well as up to US$600,000 in funding -- for their tiny flying machines.The mission calls for squads of aerial and ground robots to reconnoitre for human 'commandos' tasked with reaching 'hostages' in a building one kilometre from the launch point. The robots will need to detect and disarm simulated chemical mines in an urban environment, and guide the commandos past guard teams to the hostages -- all within 40 minutes.The robots will use a mixture of wireless communication with a ground-control team, and autonomous navigation."It's a tough competition," says entrant Hemendra Arya, an engineer at the India Institute of Technology in Mumbai. "It really gives a challenge for the designer."Micro aerial vehicles (MAVs) are hard to detect, maneuverable, portable, and more energy-efficient than larger aircraft. The United States is currently using first-generation MAVs the size of a rucksack to warn convoys about roadside bombs in Iraq.Larger unmanned aerial vehicles such as the Predator have been used for years to spot and attack enemies, but they need an airfield. The effort to build smaller craft got a boost when the US Defense Advanced Research Projects Agency (DARPA) began sponsoring competitions in late 1996. The US Department of Defense is co-sponsoring the Indian competition. more here

Hello everyone, I've got a question and am hoping someone can point me to the right places to figure this out. I am an avid r/c tinkerer. A question I have though, is: Is it possible to take your standard r/c servo, and install something into it to make it addressable? Why I want to do this is that I want to be able to control things from my handheld radio system beyond the 6/7 channel systems I have now, but not have to buy a radio system that will cost upwards of a thousand dollars to do more with it. I know, it will probably be easier to buy the uber-radio and just shell out the cash...I'd rather learn how to create something like this myself and learn some more electronic gadgeteering along the way :) I don't even know if thats the right approach, so, if you have ideas on this I am all ears and would love to hear from you. Thanks so much for reading this and I am quite looking forward to hearing some ideas! :) -Mike

I have been trying to find a tutorial, but have not been able. Basically the dc motor goes forward, hits the micro switch and turns off. Flip the DPDT switch, the motor turns on and goes in reverse, hits another micro switch and turns off again. Where do I attach the micro switches in the circuit? I'm not too gifted in this, if you could be as detailed as possible it would be much appreciated!
