DIY PSU?

I currently have a HP 6623A bench top PSU which is amazing to say the least but I never end up using all of the features and its pretty big. It regulates voltage and amperage but I really only need a really good variable voltage bench top PSU. What I need: 3x 0-12V 3A outputs What I have: tons of computer PSUs, wall warts, and everything in between. What I was suggested to use: 3x LM350T 3x 5k pot running off the 12V rail of a PSU. Does anyone have a suggestion for a better configuration? Is there a better variable regulator you suggest? -Thanks!

DIY Transistor?

Do you think it'd be possible to make a completely homemade transistor? Not a homemade transistor amp or anything, just the transistor. I know, you could just buy one for cents, but you can also just buy a lot of stuff that you can have fun making. What about turning a normal transistor into a phototransistor? Just sand the coating off the silicon?

DIY Railgun?

Hey guys, I recently built a coilgun and want to move to something bigger, namely a portable railgun. Check out this link: https://www.youtube.com/watch?v=xqxB6I6rooI I want to do something similar, perhaps in pistol form. I have more power (450v 1120uF) than the one in the link and have graphite to use as projectiles. What kind of range can I expect? And how powerful could it be? Can it be done? The requirements seem pretty simple.. (If I make it, Instructable coming soon!) Thanks. BTW I have lots of experience dealing with high voltage.

Multimeter DIY Repair?

I have a Radio Shack digital multimeter, Model 22-174. Since the 10 Amp measurement circuit is not fused I blew this circuit and that part of the meter does not work now. I like this meter and would like to know if I can DIY repair it and what I need to do. I have looked around the Internet and have not found any information including the Radio Shack site. Was looking for the wiring diagram only found a parts list. I hope that I can fix it. If I can fix it I will fuse the test leads (black lead) or work out an internal fuse for this circuit so I don't repeat my mistake. Any help would be nice. Thank you.

TSA and DIY intervalometer? Answered

DIY Solder Pot

Just today, my brother offered to give me his old coffee maker that he had replaced with a newer one. He is well aware of my electronics hobby, which is why he offered to give it to me in the first place. Nothing is wrong with the coffee maker electronically - he just didn't use it for a long time in which it became moldy on the inside. He cleaned the inside properly, and as a precaution I did it a second time. Now that it is cleaned, I'm curious as to if I could turn it into a solder pot. Seeing plenty of DIY solder pots, I'm thinking I could use an empty soup can, cut to a reasonable size, and have it rest on the heating element of which the coffee pot would normally rest on. Would I be able to do just that or no? Any suggestions as to what to use for the "bath" or "pot" of which will hold the molten solder? Thanks in advance! P.S. This is a basic electric drip coffeemaker I'm wanting to salvage - just to clarify.

DIY Plexiglass Window

Hey guys, time for another update of what I've been up to lately in my spare time. The other day I just finished a project, where I decided to take some scrap plexiglass and install it as a window in the top of my subwoofer, just like how more expensive pre-built subwoofer boxes have them. I tried to take pictures as I went along with it. Trust me, I may only have a handful of picture, but it took A LOT. Most of the hard work was chiseling the MDF board to fit a groove for the plexiglass to sit in and make a seal. P.S.: Chiseling MDF board is like chiseling cardboard, very easy to take too much out! Also, does anyone have any ideas as to HOW I could get some of the deeper scratches out of the plexiglass??? I'll be taking it apart to re-bevel the edge of the seal once I find the damn wood router, so when I do that I'd like to buff the plexiglass out a bit. Also, I think I own bragging rights for doing this.

DIY Soldering Gun? Answered

My 40W soldering iron is a bit too weak. I've been thinking about making a soldering gun, but it confuses me a bit... Since I don't work with sensitive electronic components, I don't think there's a problem. I also like the fact that I can control the amount of heat easily... I soldering gun is pretty much a "mix" between a soldering iron and a welder, right? Similar to a hot-wire styrofoam cutter. Maybe I should call it an Incandescent soldering lamp...  A hot wire cutter is exactly like a soldering gun, except it uses a thicker, shorter, wire that has low resistance... To make one, what I need is a power supply that can supply: High current, and low voltage (Wikipedia doesn't define low voltage), right? With a 5V 40A ATX power supply, a switch, and a single core wire that has close to 0 resistance, do you think I would be able to make a soldering gun? A 5V ATX power supply is the power supply with the lowest voltage that I own.  I don't know the resistance of the wire that I can use, because I don't know what wire to use, and don't know the current it will take. I know I will need the heating wire of the tip to be a higher gauge, so it will have more resistance on high amps, and it will be the one that will heats up. From what I'm guessing, 5V is too high, and something like 1V would be better. Perhaps I'll find a way for stepping it down to a lower voltage...

My current guess is that when plugged into the target device the capacitors are charged and once the array reaches a certain voltage it is shorted across the data terminals.

DIY Steering Wheel

Hello, I'm new here. So, lately, I've been thinking about making a steering wheel for my PC, with a simple up-and-down gear box and 2 pedals for acceleration and brake. Steering Wheel. I'm using a polystyrene sheet, to cut out a wheel from it, and in the center, there's space for installing a phone holder. I'm planning to use my phone's gyroscope and simulate it to the PC. Pedals. I've figured by using foams underneath, we can place a nail and a foil separated and when we press the pedal, the foil touches the nail and circuit gets completed. I've a general idea, but I'm stuck on how to give that signal to PC as to simulate as a button (say for acceleration and brakes.) Gearbox. For the gearbox, I figured it might be easier to make an up-down box (as in pulling the level shifts the gear up and vice-versa.) Here too, The part where I'm stuck is giving the signal to the PC. Anyone who can help me, please?

Diy Spot Welder

Hello, this is my first post here at Instructables. I will get straight to the point. I plan to build a diy spot welder. However, in most of the diy spot welder projects I have looked at, including Hack a Day and Instructables, a MOT (Microwave Oven Transformer) is used. The secondary is rewound with thicker wire, and the transformer is used to step down voltage and step up current. I have heard that these transformers can supply as much as a kiloamp at very low voltages. However, I do not own a MOT, they are too costly to buy, and I do not want to retrieve one from a microwave because- A) Nobody happens to be throwing away a microwave in my area. B)The guys who own the scrap metal and thrown away appliances will only give me a microwave oven at a hefty price. C)I would prefer to live a very long life, and do not want to gt myself electrocuted poking around the innards of a microwave. SO, I did a thorough search, and found that some people made a welder from a stereo amp transformer. Again, I did not own one, but what I did own was an ultrasound generator that was supposed to drive away rats. After making  bloody inroads into it`s innards, I found a transformer quite a bit larger than the regular step downs. It is 5 cm long, 4 cm wide and 1.7 cm tall.  Input voltage is 220 volt AC from the mains, at 60 hertz. Output is 12 volt AC at a maximum of 300 MA. Speaking from experience would anybody please tell me whether this is suitable for a spot welder? Please ask me for additional information, including pictures, if required. Thank you.

DIY Jib Crane Kit

It's been years since I've posted here, but I have an idea that might benefit those who like to make short films on an indie budget.  I've had a design for an all-aluminum and stainless DIY jib crane kit that I could sell for under $180. It would have full ball-bearing movement and axes that can be locked. The kit would come with all of the hardware and parts except for the tripod and the aluminum rails, which every home depot and lowes sell (1"x1"x6-10' box aluminum). I would supply templates for the holes.  I'm in college now and without a machine shop, but I know of a shop that could mill the parts out for enough money to allow me to offer the kit for a nominal fee.  Keep in mind that there really is not a kit or crane out there that can lift 20-30lbs (and be completely waterproof) for under $350. Most cranes are even more than that.  Before I put the details of the plan on paper, I need to know if there's a market for something like this, because the initial investment is a few hundred dollars and the shop doesn't do small runs. Parts would be 100% CNC'd and anodized for a nominal fee.  My questions: -Where and who should I market this to? -What forums would have an audience that this would appeal to? Any help is appreciated, I'm not so much into videography as I am into making photography equipment.

Circuit for a simplified DIY galvanometer?

I'm putting together a DIY performance lighting show set as a project and I'm currently working on the laser aspect of it. I've looked into the Galvanometers, which are used in laser shows and those units go anywhere from $60 to $200 a pop. So One thing is that I don't need to create any advanced imagery, I just need to vibrate a mirror at a fast enough rate in order to make a laser spread. My current solution is this: https://imgur.com/a/Cb6ev Basically a small motor pivoting a mirror along the axis. What I am wondering is, is there something more suited for this that isn't a motor or an expensive galvanometer. I've seen people attach a small speaker and supplying a pulse signal to make the speaker membrane rock back and forth. The volume of the sound would control the amplitude of the vibration but the downside is that it's actually audible, even more so than the motor. I remembered this episode of ElectroBoom, where a coil wound around a hollow cylinder would produce a magnetic field which would pull a metal object towards the center. https://youtu.be/mdZo_keUoEs?t=1m54s Before I would go off trying to attach a metal rod to a spring and repeatedly turn the electric magnet on and off to simulator osculation. Perhaps people would know of something like that which already exists?
