Homemade Electric furnace current question

Good day viewers! I recently found out about the wonders of electric furnaces, cheap to run and no smoke. I went looking around for some designs, there are some nice i'bles about it and I got very exited since my neighbours already start nagging when I strike a match, an electric furnace would be the perfect solution. I decided to go with kanthal wire, its relatively cheap at a few bucks per meter, and it can handle temperatures up to  1300C. I plan to melt alluminium and maybe some brass so I should be fine with that. now to the questions part, I have an ATX PSU with a 12V 16A output (DC), I was wondering how many (centi)meters or inches for the americans under us, it could power (if I can power it it would eventually go up to full temp right?) I am a complete nitwit at these Ohms formulas and electric furnaces, at the moment I am abstaining from sleep to build this furnace and I am sure that others are as well. I hope some nice fellow diyers can help me with it. This could be a dumb questions, maybe I need a wall outlet (230V in my place) or maybe I need some rocket science. I don't know, do you? kind regards and a thank in advance from 2 young exploramenters that want to melt some metal without ruining our lungs. excuse us for spelling mistakes, this written by non-native speakers and with shaking hands,...

Making something instead of buying is waste of time?

While searching the Internet for someone that has made their own Hot Press for making WPC (wood plastic composite) boards, I stumbled upon a Tshirt forum.  A man had posted a topic about how to make his own Tshirt heat press for making Tshirt designs.  The other forum members all decided it was a waste of time.  He should not bother trying because it's complicated.  In the end he would spend way more, and he could buy a used or cheap heat press locally. Is that not the ultimate irony?  People who post in a forum about making Tshirts tell another member that do-it-yourself is a bad idea.  Like buying a heat press to make your own Tshirts is a much better idea.  Do they all think they will be the one with that great design to put on a Tshirt and corner the elusive $100Billion Tshirt market?  Or do they just like to make their own Tshirts instead of buying one pre made.

Coanda effect in conjuction with Venturi effect !?

I am still working on my project to create relatively accurate model of a Repulsine. No, I am not one of those free energy nut balls, just curious in old tech ;) As part of my research I came across some statements in regards to lost pieces of the Repulsine. The last remaining model still exists in Austria but noone seems to have to clue what the missing parts looked like. I think the missing parts are a system of nozzles, diverters and a secondary hull - forming a similar system like the Coanda plane engine. There are lots of people still out there tinkering with Coanda lifting devices and trying to get them working. Is there anyone here doing it ??? Would like to exchange some knowledge, tipps, designs and so on. Short term goal is to make working Coand engine with enough thrust / lift to be used at a later stage for a working Coanda plane model. Long term goal to modify it all to incorporate into the Repulsine.

PEMF device that mimics earth's magnetic field?

I am very interested in making a pulsed electric magnetic field device that mimics the Earth's own magnetic field. It could be as simple as one single coil. That coil would have to have a magnetic field that measures in the 30 to 90 microTesla range, and it would have to be able to be pulsed in the 5 to 45 Hz frequency range, since that is roughly the strength and frequency of the Earth's own magnetic field Any ideas on how to make that happen? I am a reasonably intelligent person, but I am not necessarily technically gifted. So for somebody this might be uber simple, I don't know, but I am just not sure how to go about doing this. What do you think?

208/240 transformer question

After having several (like 4) thermostats fail in a 6-year period, it finally dawned on me to check the voltage from the transformer and I found it to be a bit over 28 volts. My condo building has 208V service. The transformer in my air handler is a 208/240V one and was wired to the 208V terminal. I removed the wire from the 208V terminal and connected it to the 240V terminal and then found the voltage to be 24.2V. So I have possibly solved the problem of the thermostats failing but my question is, will this cause any damage to the primary (or secondary) of the transformer? Thanks in advance!

Motor and base design for optical toys

Hello everybody! I'm in the process of building a reiteration of a series of optical toys (like this one, or these) with motor, stroboscopes and little music system. The thing is their discs measure about 1 m (like 3,2 feets) and one of them (praxinoscope) is a heavy one due to the mirrors it possess (see photo [it isn't it's actual state]) so I created a metal base for it with a tube, three metal angles as legs and washing machine 115v ~60hz 70W 250VAC single phase motor soldered on (with capacitor), so the disc sits on top of the motor, and the thing is that after an hour of so of being tested on continuous duty it stopped and started to smell like burnt. What could the problem be? Could it be a design problem since the motor has all that weight on top? Should I have used gears and pulleys? How can I make it last longer without it being to complex?  If someone can help or has some ideas I'd appreciate it , thanks in advance! Benkos M. G.

The FootHold Snare

One day, you might find yourself lost in the woods while camping! One day, the stock market will crash and are YOU ready to survive? Traps and Snares are one of the most important things while surviving. Blake Alma, the founder of The Art of the Outdoorsman once said, "A trap is as someone else hunting for you when you can't, it is truly your best hunting buddy!" This is so true. Unlike fishing poles and firearms, traps and snares work when you are sleeping! Hence, learning how to make a simple snare indeed helpful and lifesaving for it is an art of an outdoorsman! Let's get started on this foothold snare. You need: A shovel, 550 lb. test paracord, and bait. Note: There are laws regarding trapping. Step 1: Digging your Hole Picture of Digging your Hole I hope you got a good shovel and back! You will need to dig a hole 2 to 3 feet deep. Yes, I know it is a true pain, but it can save your life or get you free food! Diameter of your Hole: - Raccoon/Opossum/Mink/Groundhog/Large Rabbit (6 inches) - Coyote/Fox/Bobcat (8 inches) - Animals under 550 pounds/Deer/Small Elk/Very Small Bear/ect. (12 to 18 inches) Step 2: Camouflaging After digging your hole, add leaves, thin sticks, tree bark, or grass over the hole. Do not put to much "camouflage" over the hole or else you may prevent the animal from falling down in the hole. Step 3: The Snare Wrap the paracord around a stick or you finger making a small loop. Tie the small loop, and pull your finger out. Make sure the knot is very strong. Put the other end of the paracord through the small loop. You should then have a giant loop, known as the snare itself. Make the loop's (snare) diameter slightly smaller than your hole's diameter. Tie the snare extra line around a tree, sapling, or log near by. Make sure it holds. Place the snare itself over the hole, on top of the "camouflage". Step 4: The Path of the Least Resistance Sense the animal has plenty of ground to step on, it might be hard to get him in your hole. Hence you need to create a the path of the least resistance. You need to make him limited to where the animal will step. Make a path to your foothold snare using leaves, sticks, logs, and grass. Make it easy for the animal to walk through. Like us we want to walk on a nice smooth sidewalk, not on a beaten trail. They want to walk on a path with the least resistance, they don't want step on pointy sticks. They want to step were the feel most comfortable. That is way you need to make a path to your snare, so it will step into your snare! Step 5: Baiting your FootHold Snare Picture of Baiting your FootHold Snare Place your bait two to three feet ahead of your foothold snare. Raccoon and mink like fish. Opossum like processed meat like hot dogs. Groundhogs like sweet apples. Coyote and fox like meat. Deer like deer feed (duh!). How it works: The animal will smell the bait and take your path of the least resistance. While walking up to your bait on the path, he will step his foot in the hole. It will pull his foot out of the hole and continue walking. (When we pulls his foot out the snare comes out with him.) Then the snare tightens around his foot, making him trapped.

Bolt Action Rotary Magazine Gun (updated with internals)

Alright, it's been a while, forgive me. I work in spurts of an hour or two every few nights. It's not quite finished, but it's at a point I'm comfortable showing. I'm also working with BM, so hopefully he can make some improvements on it before it's posted. This gun is the combination of two different goals I've had. First off, I always wanted to make a bolt action. I came up with the idea for the modern bolt action long ago but was beaten to the punch. So since then, as others have made their own bolt actions, I still struggled to make one up to my own standards. I wanted something sleek and compact with a removable magazine. Second, I went off on a little tangent while building, which then turned into its own project: a rotary magazine. While it's been done before, I don't know if it was ever successfully used in a gun. It's more about the novelty than the practicality, but what it does do is give you more storage in a compact design and act as a decent foregrip. I wanted to make it a decently usable. At first I thought of making just some cruddy gun to show off the concept as a usable magazine, but then I decided I may as well go the full nine yards and make it perform well. So this is what I ended up with. I don't have a real name for it yet, but I've considered calling it the Barackuda, a portmanteau of Barack (Obama) and barracuda because...well why not. I wanted to keep it as compact as possible, so I used a barrel similar to my Oodassault 3 series and a stock connection similar to my PDR. The stock is a bit long compared to the body of the gun, so it may look awkward, but I wanted to give at least enough room to aim the gun without sticking the pin into your eye. The blue connectors in the stock stop the bolt right after the trigger engages. The bolt is somewhat typical. I like how it sits flush with the back of the gun rather than looking like an extension on the back of it. The handle isn't amazing, just a variation of my tried and true handle I've come to like. The trigger also isn't amazing, and in hindsight, I want to block a bit further back still, but it works for the limited space I've got. The magazine on the other hand is magical. Go look at my last topic for details on its operation. This version is for yellow rods. I've added a rotary lock and band. When the middle rod is pushed toward the trigger (like in the pic), it's locked. It can securely contain 10 usable yellow rods while locked, though it can load up to 12, the top 2 can fall out. You insert it into the gun by pressing the top two red rods at an angle into gaps in the grey connectors at the front, then rotate the magazine, slightly pushing in, until you get the white rod in the gaps of the yellow connector. Finally, you push in the middle red rod by the trigger all the way forward to unlock the magazine. Edit (9/10/2015): Made my adjustments and now I'm mostly satisfied with the weapon. Here's the video.

ATX PSUI shorting out

​Hi everyone, I hope I did this well, first time on this site, this is a question. I want to make my own soldering iron/heating element, I know I can buy them but it is a project of mine and I just want to know how it works and make it. I used to power a copper wire with a 5V ATX PSU at 16Amps, the psu shorted out and stopped. I read somewhere that you can prevent the PSU from shorting out when there is enough resistance on the wire so the current is not too high for the PSU. (Total nitwit on electronics btw) I was wondering if this is true, and how can I build a succesful soldering iron with a PSU, what transistor or what modifications to make. Also, would a longer wire/rod produce more heat than a shorter? red hot would be nice. Thanks in advance!

I really liked the compact design of his version, but he never finished it, so I can't buy that kit ;-( Is there a simple way to put together something that is protected (so I don't kill the USB socket I get power from) and has a Variable Volt and Amp adjustments knobs/buttons. I've looked at getting a full size Bench Power Supply, but would love to just have one so that I can power from my laptop or any of my million Micro USB power adapters (5v 500ma through 5v 3A supplies). My first project is something I need to eventually run off of AA batteries, but I didn't wanna keep on re-charging the batteries while I test my circuit design. Would rather have a constant source of 1.25v-1.5v power during the prototype phase. I'm just now getting into Electronics, so please take it easy on my poor little brain. Hopefully this hasn't already been asked, didn't find anything in my quick search through the forums.

LEDs at less than forward voltage ; no resistor??

I'm new to playing around with LED's, so please forgive the ignorance.  Right now I am trying to make a homemade lamp of sorts.  I am using white LEDs with the following specs per the seller. FW current - 25 mA FW supply - 3.3V (typical), 3.6V (max) Tested one LED with two AAA batteries and no resistor.  I was told by radio shack guy that since supply voltage was less than FW supply I would be fine, and the LED would pull the amperage it needed.  Lit up and looked fine to me. I then found a 9V DC wall wart, and decided I wanted to run possibly up to 12 LEDs using 4 parallel strings of 3 LEDs in series (9.9 volt drop across each series).  I bought a multimeter and checked the DV voltage from the power supply, and it ran consistently between 9.1 - 9.2 volts.  The thought with the 9V wall wart was that the voltage supply would be lower than the FW supply, thus I would not need resistors, simplifying and reducing # of connections needing soldering (new to that as well). My question is, will this 9V work for my system?  I've tested 3 LED's in series, and also 2 parallel strings of 3 LEDs in series, and both lit fine.  I've read posts where people say that the lights will not light up or will be dim if the FW supply is not provided.  As mentioned, they seem fine to me, and as this lamp is planned for more of a mood lighting, I don't need it much brighter.  Is the only downside a dimmer light?  Will it last just as long?  My main concern is putting the time and effort into constructing this thing, and then having the LED's fail for some reason I don't understand, and having to rewire it all.  I've thought about buying a 12V supply and using a resistor, but would rather not unless there is a good reason to do so. Thanks in advance for any input!
