Test Pc

I saw a computer on here that was made on some sort of shelfing, and I was wondering what it was called exactly. There was no case, and it was used to test other parts. I recently came into ownership of a server motherboard and a HUGE motherboard with over 15 extension slots and I want to make this. Please help! NOTE: I DID SEARCH FOR IT!

Testing a NST with a DMM?

I have been looking for a good (and cheap) NST for a while but i dont want to risk spending too much on a NST that doesnt work. I know that my local scrap yard has a large supply of old NSTs that are either there because both or one side doesnt work, they were upgraded, or someone needed the money and/or space. i also know that they would frown upon me wiring each one up and testing each. so onto the real question: is there a way to test a NST with just a multimeter and possibly a battery (i know thats how some people test for flyback transformer pins) or if checking continuity would be enough or even another way? Just so everyone knows i have spent quite a while searching for someone using this technique but didnt find anything, also im looking for a way to know for sure if one or both sides are working.

Testing a Cheap Multimeter

It's been years since I had an expensive meter. These days, I have meters in the $5 to $20 range. Usually they're accurate enough for my purposes, but what if I want to be really certain? Is there a way without a pricey meter to test em?  Perhaps calibrate the meter by checking v  coming out of a v regultor. Would that be accurate? Perhaps the 7805 regulator which is supposed to output 5v.  y?n? M?

Air tank testing

Water Tunnel Testing

So, my measurements professor got us permission to fill and fire up the water tunnel in the measurements lab.For those that don't know, a water tunnel (like the one below), pumps water from one end of a tank to another. The water goes through a conditioning filter (to make the flow nice and even), and then it passes through a tunnel (that blueish area in the picture). You can then add dye or solids to the water to see how a fluid flows over the object.We're allowed to bring in one item (per person) to put through the tunnel. The tunnel is a little more than a foot wide. What would you like to see in there? After the lab, I'll post up pictures (and possibly video) :)Keep in mind that the object should be heavier than water (e.g. no balloons :P). See the photo results here!

Test yourself for Aspergers Syndrome

Aspergers Syndrome has only been recognized since about 1995, we call ourselves Aspies. Try this test http://www.rdos.net/eng/ make sure you follow the instructions the results will only survive for an hour, so download them ASAP, the picture (a pie graph) or Aspie-Rating-Picture (ARP) and final score, you can chose to show to people, but the questions and answers are very personal, keep those to yourself. I plan to put my ARP here, that is something us Aspies enjoy displaying, something to be proud of, I hope that other Aspie group members put theirs on. Your Aspie score: 181 of 200 Your neurotypical (non-autistic) score: 28 of 200 You are very likely an Aspie It is possible to cheat to get a high score on the ARP, so I am thinking that ARPs can be voted off by members if members find the ARP unbelievable when comparing the member's ARP with said member's profile and activities on Instructables. Aspies don't practice discrimination, so even if you don't have Aspergers Syndrome, consider yourself as a honorary Aspie and sign up anyway. Visit https://www.instructables.com/community/Analysing-your-test-results-for-Aspergers-Syndrome/ A free for all, discussion on self analysis of your test picture (a pie graph) or Aspie-Rating-Picture (ARP) and final score Another link for Aspies is http://www.psychforums.com. I will dig out more shortly, I have list somewhere, but that one was not it I recall.

new knex gun test?

Some of the micro Knex kits come with bricks, which are useful for testing a gun's strength. for example, my bolt action shotgun (youtube) has a strength of about 60%. A standard brick for building these would be a 2*4. 5 rows and five columns. how many were destroyed divided how many in total standing would get your average. I shot at about 10 feet. Hope I helped revolutionize k'nex strength tests...

Finding a builder to test a prototype

I am working on an item, and it requires a small bit of dimensional lumber, ply, and screws. I am trying to make the plans as specific as I can, but having worked in the engineering field as a draftsman many years ago, I know that mistakes can and do get made. So, I am wondering how I would go about finding someone to test build (without fooling with the wiring and such for the electrical components) my plans to find any errors or oversights, inaccurate or unclear directions, and the like. How would I go about doing that? Is there even a forum on Instructables for people to be test-builders? That would be a great thing if there were.

Testing LED light strips

More questions regarding this: https://www.instructables.com/id/How-to-make-a-super-bright-LED-light-panel-for-vid/ I've added my 30 led strips and have soldered them in place.  The video says it's a good idea to test your strips at this point by connecting them to a power source. I presume it means to connect the two paired wires on the back of the panel to a power source.  However, I don't know electronics so I'm not sure how to do this. I have a 12v AC adapter as well as some other power adapters from old laptops.  How do I connect this to the wires? Is there a link to an existing instructable that might explain this for a newbie?

Testing a 3 watt LED? Answered

I recently purchased 13- 3 watt LED's. I'm trying to establish a high out-put LED light. I also purchased a LED Driver Transformer 48 Watt 120 Volt to 12v DC 4 Amp. First I would like to test each LED using the same divider. I'm thinking that if I create a voltage divider two 330 ohms to limit the current and reduce the voltage to about 6 volts that would allow me to test with the driver that I purchased. Secondly, will this driver be enough to drive all my LED's and would I have to reduce the voltage down too since it appears to push out enough wattage and amperage for the total number LED's I'm putting together? I'm building my circuit based on this video. http://www.youtube.com/watch?v=4qYZahe2s5o&NR;=1 Link to website data of 3 Watt LED. http://ledsupply.com/indusstar-1up.php Assistance would be greatly appreciated.
