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?

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.

test RJ45Cat5 to USB Female

I'm new to this forum. I need some instructions. I have an RJ45-cat5 male to USB female connector that I bought for 3 bucks. I've tried using it to connect my HP 1050 j410 USB printer to my Linksys WRT54GS (wireless) router so I can have a network printer. (The Desktop is directly wired to the cable modem and the to the router.) It doesn't work, but I don't know if it's the connector itself, or that the printer will not communicate with the router, directly. Is there a way to test the connector with another piece of hardware to determine whether the connector is actually any good? BTW.. I can't determine from HP, whether the 1050 j410 USB printer can become a network printer. Should I just go buy a USB print server for 20 bucks, or whatever? I'm using an Ubuntu 10.04 LTS Desktop with AMD-64 processor. Thanks to you for the best advice. Shobuz99

best way to test an alternator?

We are having some electrical problems with a john deere tractor, and received an error codes 61f, 018, 023, 026, 049, and 051. These error codes are not cleared when the problem goes away, and from memory, the first few meant low fluids at some point, and one of the later ones is indicating the output of the alternator is outside of normal operating range. The problems experienced: * The tractor would start, and "lunge" forward but never actually go any go further than 4 feet. * reverse does absolutely nothing. * hydraulics work fine * Engine would start in any gear, when it should only start in neutral. * Replaced a few dead fuses and a missing relay but these did not change anything important. * oil / hydraulic fluid was very low, we fixed that. * this lunging behavior was intermittent before, only requiring some wiggling of the gear shift. * requires jumping in order to get started. Does not always crank fast enough by itself to start on its own. Today, we plan to test the alternator to see what's going on there, It is rated to deliver 115 charging amps to a huge 12V battery. what is the best way to test this with a basic multimeter or some basic around the house parts? I measured the voltage across the battery rise from 12V up to 14V, so it would seem that it's fine, but I'm going to take that with a grain of rice. Is there a better way to measure the alternator?

I'm starting a new topic so I can edit it later with more content.I went with some friends to a different lab section that was also playing with the tunnel (my official turn is on Friday).Things put in:1. PVC tube -- to show detachment of a cylinder2. Golf Ball -- to show how dimples create turbulence and keep flow attached longer3. Tennis Ball -- to show how fuzz acts almost like golf ball dimples4. Porsche 9115. Atlantis Space Shuttle6. Porsche 911-turbo (or possibly a 935 or 993 -- can't remember)7. Chain Mail Cube -- wtf? why did someone make that?8. Surf Board Fin9. Optimus Prime10. Unknown Porsche (I just can't remember what it was)11. Batting Cage BallThe pump was set to 3.55 inches per second. So for a 1/64 scale model (for the cars) - that's just under 13mph equivalence (in water).My camera had a low battery -- so the shutter was slower than normal. I'll get fresh batteries and a tripod on Friday I'll have some better pictures (hopefully).As for what I'm bringing in... Still don't know -- but I think I am going to do a comparison of apples and oranges :PVideos of the 911, 911turbo, unknown porsche and of the overall tunnel in operation ;)Update November 3rdItems Tested:1. Plastic Cone (with hole in top)2. Apple3. Eyeglass Case4. Obligatory Altoids Tin5. Plastic Water Bottle6. Highlighter Cap7. Reverse Gear from a manual gearbox (Nissan)8. Pen Cap thing9. Rubber Duck10. Nerf Dart (velcro top)11. Batman Shield (this was really cool)12. Welded Plate13. Golf Ball14. Guitar Bar15. Wing FoilAgain, it was set to 3.55 inches per second. I couldn't find an orange on campus (weird considering I'm in central Florida :P). So I'd say an orange is kinda like a golf ball :PThe Bat Shield video is very cool - if you watch just one of them, make it the bat shield ;)
