I have used modded computer power supplies many times to power my creations, but in the past I have always relied on just using either the +5V red wires, the orange +3.3V or the +12V yellow wires. However, most sites that offer advice on diy lab power supplies always say to hook the 12V to the 5V to get the 7V. My question I guess is do I hook the +12V to the +5V to be the new +7V positive, and then rely on one of the black ground wires to be the negative? Or, is it the +12v wire hooked up to my 7V devices positive lead and the +5V wire hooked to the devices negative lead? Any help would be great, kind of stumped. Multimeter was lent to a friend, and I'm not really in the mood to fry electronics to test it. Thanks and sorry for the oddly worded question, having trouble following myself at this point.

Does anybody know how to go about recreating the Casimir effect outside a lab? Say I have a vacuum chamber and two copper plates. I want to create the Casimir effect within the vacuum chamber, Only problem is that to do so, from my understanding, I'd have to have the copper plates within nanometers of each other, I've heard of methods using oscillating crystals...can anyone help me?

I am trying to build a variable power supply using a LM317 variable voltage regulator. When connected to no load, i can get a sweep from 1 volt to 15 volts. but when a load (small pager motor, laser diode) is connected, i can only get up to 4 volts, and about 12 milliamps of current. Help!

If you were a "mad" science teacher, what experiments would you show your classroom of students? We're looking for a WOW! factor here, something memorable. Parameters for this experiment include (1) large capacitor such as a 1.2 Farad capacitor, and cheap or easily found parts to demonstrate experiments. Trying to avoid items that cost much or require lots of time and effort. (Building a Tesla coil would be an example of something that takes too much time or work.) Thanks Instructables community!

I recently received 2 old computers from friends for tinkering purposes. I'd like to take their PSUs and create a power supply for projects. However, they only have max outputs of 110W. So, I have a few questions: 1.) Is it possible to combine rails? 2.) Is it safe? 3.) What kind of power increase would I be seeing? Please try to answer all 3 individually.

Question by coleyy | last reply
Now that I have a new oscilloscope (rigol DS1054Z), and have learned a LOT about programming and electronics while down at NASA langley for a research program (semi-intern), I feel like I should start working on a real project (other than my quadcopter), and was thinking about making a nixie tube clock. I would like to make it from scratch of my own design as I feel one learned the most about electronics by not using other's designs. However, I do not have the resources or time to bother trying to etch my own PCB. I attempted that before and was not able to get usable results. What kind of costs am I looking at if I locate a relatively local company for the job? I hate calling people and companies, but I suppose that is still the most practical way to figure out what I need to do and place an order, I don't know. Economies of scale is a great thing, makes things in bulk production cheap! However, would the costs of ordering one or 2 PCBs be non-economical and/or non-practical? Should I consider many smaller projects and stuff to be created on a breakout board? I hate messy, sloppy protoboard, it is just nasty, though easy for non-high-density boards. however, I would love to hear the opinions of others for these things. When dealing with nixie tubes, are sockets for the 1N-14 avalible? A lot of the new old stocks seem to have very thin and long legs, almost as if they are meant for through hole soldering directly onto a PCB like capacitors and resistors. I would prefer a socketed tube to make replacing them quicker and easier.

Question by ashok -1955 | last reply
Hi all, I want to turn an old computer PSU into a lab bench PSU. After cutting all the connectors at the end of the cables, I've noticed that some of the common (black) wires were made of copper, while some of them were made of nickel \ aluminum (Silverish). The same is true for the +5V (red) cables. It's not the first PSU I noticed that had the different materials, and I was wondering: 1) Why are there two different kinds of wire? 2) Is it OK to ignore the wire material and just splice all the blacks together, and all the reds together? Thanks!

I want to use a lab power supply to run simple ohm's law experiments instead of using a 9v alkaline battery. One of the experiments uses a resister in series with an LED to show the effects of how a resister limits current. I can set my lab power supply to 9V but I don't know what current to set it to in order to be the equivalent of the 9V battery. Can anybody enlighten me please?

Question by jshpps | last reply
This is what I'm talking about. can you see it? it's the first thing that comes up on google image search when you type in "lab supply jumper." It's so you can plug in a tattoo machine and foot pedal into a lab power supply. theoretically I get how it's working. The foot pedal is what interrupts the circut. when you press the pedal down, it makes contact and completes the circuit. So, the machine needs to be routed through the pedal before getting power from the power supply (versus plugging the machine directly into the PS itself. Cause then you'd have to turn the PS on and off to get the machine to work or turn off). So, I'm assuming that's why there is a cord going from the "machine" 1/4 terminal to the "foot pedal" 1/4 term, right? Then the pos and neg banana plugs go into the power supply. specifically, my question is this: do I have to solder to make this? or can I just twist wires together? and can I buy everything I need from radio shack, right? I'm pretty confident I can do it either way, just need a diagram or something on how to wire everything. I'm also asking my brother who was an electrician before getting injured on the job- he's on disability now but may be able to help, too. =) It's gotta be easy to make, right?!?! so help me do eeettt!!! =0) thanks for any and all help! Sarah ps- I attached a pic of the power supply I have so you can see it as well. and for the record, my tattoo machine is RCA not clipcoard, but goes to a 1/4 male mono all the same. As well as my pedal. k, thanks. ;0)

I have instructions for extracting pure esential oil from plant material using butane. The problem I have with it is that at the end, the butane is vented. I just don't feel right about venting unburned hydrocarbons into the atmosphere. I've been looking at glass lab equipment (distillation tubes, connectors, etc). I have no background in chemistry, but it seems to me it shouldn't be too difficult to put something together using standard glass lab equipment to capture, distill and reuse the butane. Butane boils at 31 degrees farinhite and is heavier than air. At the end of the process, the oil is scraped from the bottom of a drying dish. Does anyone have any suggestions on how to put something like this together? Thanks

Saul Griffith from Squid Labs, Howtoons, Instructables, and other cool companies has been awarded the MacArthur "genius" grant. He gets $500k because he's so genius-y and it couldn't be going to a better guy. Saul Griffith is an inventor whose innovations span industrial design, technology, and science education. Through a variety of endeavors at MIT and as a principal in Squid Labs, Griffith demonstrates his boundless energy for inventing across diverse disciplines in the global public interest. While still a graduate student at MIT, he designed a unique membrane-based molding system that can produce a variety of common lenses from a single pair of flexible molding surfaces. This prototype has the potential to change the economics of corrective lenses in rural and underserved communities around the world and continues to be a major focus of research and development energy at Squid Labs. At MIT, Griffith co-founded Thinkcycle.org, a web community that has produced socially conscious engineering solutions, such as novel household water-treatment systems. Thinkcycle.org is the forerunner of Instructables.com, a remarkable do-it-yourself website driven by user contributions. He is also a creative force behind HowToons, an animated educational resource designed to engage children in hands-on science and engineering projects. Through the spin-off company Potenco, Griffith initiated the project design for a hand-held human-powered generator, which has the potential significantly to improve access to electronic devices such as laptops and water purifiers throughout the world. Though still quite young, he holds several patents in optics, textiles, and nanotechnology. In these engineering ventures as well as others yet to be imagined, Griffith is a prodigy of invention in service of the world community. Saul Griffith received a B.MET.E. (1997) from the University of New South Wales in Sydney, Australia, an M.E. (2000) from the University of Sydney, and an M.S. (2001) and Ph.D. (2004) from the Massachusetts Institute of Technology. He is a co-founding partner of Squid Labs and serves as a technical advisor at Potenco in Alameda, California. full story
