The Neverending Powersource

Energy has to come from somewhere. A motor, when turned, creates electricity from the terminals. When electricity is applied to the terminals, the motor shaft moves. Backwards compatibility, anyone? The sun constantly gives off energy. The suns energy is used to grow food. Continuing on with the theory. So, in this example, energy came come from the sun, which goes into plants. Now, we can make the plants into ethanol, however, the amount of energy burned from ethanol is almost equal to that producing it. BUT, if we do not use the plants to make ethanol, humans can eat it. That, in turn, lets us function and work. Now, do you know what the near neverending powersource is? Do you? Animals. Humans in particular. So, to create electricity, we need some form of generator that creates electricity when work is applied to the generator. Hmm... I know! A bike generator! A human pedaling a bike generator that is connected to a motor creates electricity. Basically, we are more efficiently harnessing the suns rays. Yes, I have accounted for the amount of energy it took to produce the bike, motor, and other unneccessary accessories humans MUST have on that bike. But eventually, We may overcome the amount it was needed to produce those things. So, I will soon be creating an instructable on a bike generator, created from your previous/preexisting bike, that will be very simplistic to create and easy enough a 12 year old could do it. Remember, humans can harness the suns power even more effectively than other sources of green power. (I know this will cause a disruption in the comments, but so far, Nuclear is the cleanest, however the waste is not very good...)

NiChrome Power Source? Answered

So, I'm doing a project that needs to boil maybe 8-10 drops of water very quickly. I was thinking of using NiChrome wire to do this as in the included diagram (sorry low quality, MS Paint). However, I can't seem to find an appropriate power source. So, I need some easy to obtain powersource that is also relatively small. Something like batteries, a capacitor bank, or anything similar. Remember, it has to be able to boil of those 8 drops pretty fast, lest they condense in another part of the pipe before the desired pressure is reached.

How do I transform some kind of voltage into 5v? Answered

I'm planning on building a circuit with an ic which needs 5 volts, and I don't want to use a computer as a powersource, what can I do? Or can I use 4,5 volts for it. Thanks, BoK

How hard is it to make a computer controlled switch?

Hey guys, I was planning an instructable but I would need to create a program to turn switches powersource switches on and off. The switches would be for regular power sockets so I wouldn't have to modify the stuff I plug in. I have no idea how to do it, is this an easy problem? Where would I get the parts needed? Thanks for any advice!

With an electromagnet, if there's a open reed switch betwen 1 end of the coil's wire & powersource, will e-mag get hot?

I'm building an electromagnet. The core is soft iron: 0.5" diameter and 1" long.  AWG 12 wire OR enameled copper magnet wire 32 gauge So the wire is wrapped around the core. One wire end leads to a reed switch which connects to one of the two wires of the 9 volt snap-on battery clip. The other wire end connects straight to the 9 volt snap-on battery clip with nothing in between. Will the wire end that connects directly to the 9 volt snap-on battery clip: A.) use powers and drain the battery B.) heat up the electromagnet (wire & core) If the electromagnet heats up, then how hot does it get? Just warm or really warm? Could it reach hot or HOT levels - hot enough to burn skin, damage any part of the electromagnet, or ignite/melt the carpet (if it was on it)?   P.S.  The final device would have no exposed wires. Thanks.

Tesla illusion ideas / wireless light bulb help

So I was considering going as Nickola Tesla for Halloween and showcasing his ideas as sort of party tricks...like a Tesla turbine blade and whatnot. But seeing as he is primarily known for electricity work, I thought it would be cool if I could somehow come up with a way to make a lightbulb glow while holding it. I tossed around the idea of running a powersource to a conductive glove to power it and also of making a self contained powered bulb but not sure. Any ideas on how to make some sort of electrical phenomenon illusion? Thanks.

How to make a wireless dreamcast controller?

I've been searching for roughly a week and have not found a wireless dreamcast controller besides a very old model that uses IR and was of very poor quality.  I found a MAKE: article on how to create a wireless receiver/transmitter set but every link is dead, and so therefore, I can't follow it.  I know I'd need a powersource for both the transmitter and controller, and various chips/components for it as well.  All of this I'm sure the controller has more than enough room for.  I'd also like it to have 4 channels like the wavebird controller for the gamecube.  Any help?

ho to make a light display blink to audio?

What i want to make is a sort of light grid with LED's to where the lights will blink to music. im thinking of breakng it down into thirds. lights for bass, high and low range. what would i need aside from the powersource and the leds. i know that there is a power drop after a few leds are wired in either series and paralell and that the lights become dim.what type of resisters would i ues to maintain consistant voltage and what components do i need to convert sound waves into electrical impulses unfortuantely i cant read advanced wiring diagrams. but im getting there slowly. all i can really follow on is the symbols for power and some obvious things as such. any help would be appreciated. even if i can get 3 lights to blink to different wave lengths i can modd from there and i will post back to all that are intrested my results and ensue a following instructable in great detail. detail is goood

DSLR camera raspberry pi help

I was looking to build a raspberry pi canon battery grip (basically this thing: www.davidhunt.ie/raspberry-pi-in-a-dslr-camera/) I have some basic knowledge of the Pi and a reasonable amount of electronics experience, I was just wondering if you guys could help me out with a couple of questions as well as any other details that you think would help me build this: 1) How do you get the image data off the camera using the Pi/ get control of the shutter over USB 2) Is it possible to set up an ad hoc network to monitor and control the camera as well as download the pictures from an android phone or laptop (and how would I do that) 3) Any other ideas for cool things to do if i attach a pi to my camera? 4)The ideal powersource would be one of the canon LP-E8 7.2V batteries, anyone have any insight into a genius DIY connector for one? 5) Could it be used for recording/controling audio to videos? i.e. (http://beachtek.com/dxa-slr-pro/) but obviously more simplified 6) as an additional note, would it be possible to use the camera buttons and screen as the interface for the Pi computer (or at least the screen, so that I dont have to double to effective size by including a screen) for reference: the camera I have is a canon 600D and the battery grip is the generic type for 500/600D

2n3055 flyback transformer driver diagnosis. - Showing some sign of life Answered

Hello again instructables! Now I've finally gotten my circuit completed.  However, I can't seem to get it to work. I've tried to follow this : https://www.instructables.com/id/2n3055-flyback-transformer-driver-for-beginners/ I'm using the same transistor (2n3055) - I am however using an older flyback transformer. (see the pictures) I've also made this circuit without any success : https://www.instructables.com/id/Flyback-Driver-circuit/ (With another transistor than what he uses.)  I've also tried to 'test' the circuit using only a 1:1 transformer instead of the flyback to see if I got some kind of high pitched noise. (EDIT) After a tip from iceng I am now able to get a high pitched sound. But I am still not able to draw arcs. With my minimal knowledge, I've tried to search through the internet and this site for ways to troubleshoot it, and I've pretty much tried everything I can think of. Things I've replaced / tested - New standard wires  - Other wires for the windings - Less windings, more windings - Different transistors (Like I mentioned I'm currently trying with a 2n3055, I've got about 10 of them, so I've tried different ones.) - Different powersources : Batteries from 1.5v to 9v. - Switching around cables on the windings to try to get the right polarity - Checked the resistors. They work just fine according to my multimeter. - Checked the transistors. They work just fine according to the multimeter. - Checked for continuity where it make sense that there is, and that seemed to be correct. Hm, I think that's everything. If I've forgotten something essential, please let me know. Here are pictures of the different circuits I've tried to make, and two circuit diagrams. Edit: I've re-done my windings on the flyback, so they arn't quite as sloppy as they look on the picture. Edit : Added updates.

Convert airgun/Paintball gun to be fired by a computer (12v solenoid valve)

Hi!I have a project this summer where I need to convert a paintball marker and a co2 Airpistol to be fired by the use of a solenoid valve powered by 12v.The project goal is high-speed photography, more or less photographing object being hit by a projectile.What i need is a way to fire these guns precisely by the use of my computer and software, and since I already have plenty of 12 solenoid valves that work with this system I thought my easiest way is to adapt these valve to trigger the guns one way or another.I just purchased a Valken V-TAC SW-1http://www.valken.com/Marker-V-TAC-BLACKHAWK which I plan to use as base (for parts) My reason for getting this particular one was that it was on sale for 50% and seems to be fairly popular as it's based on the Tippmann 98 design.I attached an image of the valve I used with my controller and software (Cognisys Stop shot) now I can probably use any 12v solenoid valve (with the same spec ?) as the one I use now so it doesn't need to be these exact valves. As long as they can be operated by turning on-off power with the same powersource i use to control my current solenoid valves.From my understanding, most airguns use a pin valve, which is hit by a trigger mechanism that is then rearmed by the blowback.What would be the best way to modify an airgun for my needs? Replace the pin valve with a suitable solenoid i can control instead? Or go for a design that uses maybe use a piston and 2-way valve to hit that pin?The gun does not need to be mobile or ergonomic, it will be placed in a rig regardless, however keeping the barrel and keep the Picatinny is preferred to be able to mount marking aids etc. and mount the gun to a tripod.Any tips or suggestions are highly appreciated!Thank you!
