I mainly take on projects I have seen here and put my own twist on them. I also like to take garbage or thrown out electronics and make something nice from them. I have no certain area of Expertise, I am new at all this DIYING. But I like to keep my focus around 18650s. Was very difficult when I first started, researching anything DIY and you get terminologies, I may never understand. But I am pretty quick at figuring them out, so please ask me if you have any questions, I will give you the Bas…

  • Super Simple DIY Spot Welder Pen (MOT Battery Tab Welder Pen) 10$

    Man those look Awesome!!! I didn't even think of using solid core wire!! I bet they will stay much much cooler than the ones I made. So many people kept asking why I added the wire, and the main reason was cooling. After a few welds with basic tips, or hollow tubes, they can get pretty hot. With the added wire, they tend to stay cooler much longer and carry the current all the way to the tip easier. Great Job!!!

  • Simple Way to Convert Stereo to Mono

    I know this is an older post. But I have seen how this works when you have a Bluetooth to amp configuration. But I can't seem to find anything on an amp with built-in Bluetooth. Is there a way to create stereo to mono, or are you just basically stuck with a Right or left channel? Great explanation of the pre-Bluetooth(or signal) to amp configuration!!!

  • Super Simple DIY Spot Welder Pen (MOT Battery Tab Welder Pen) 10$

    Thanks!!!!On the build in the video, I used Copper Tubing from the local McLendon's. But on a set I built for my friend I used the same copper/Brass tubing in the link. Both worked equally the same. The Brass tubbing uses 85% copper. But the copper tub is really only there to create a handle and to hold the chuck in place, as the wire in the middle is also touching both the chuck and the lug. The combination was to help dissipate the heat generated when making multiple welds. If you don't plan to use wire in the middle, I would probably advise you to use solid copper. Just watch the heat generated by the welds.

    Check out my Youtube Channel. I have a few on there That I have built.

    It depends. I have used this with a Capacitor welder, a Car Battery Welder and a MOT Welder. I am about to release and instructable with a super simple way to control the pulse if you use a peddal. But if you go to my Youtube channel, you will see a few timmers I have built for all kinds of welding.

    I have used this with a Capacitor welder, a Car Battery Welder and a MOT Welder.

    Great Job!!!!!!

    I use to just make my own tips from solid copper. But I didn't like how t stuck when I was welding, so I tried Tungsten rods I found out the local hardware store in the welding isle. The Tungsten rods worked well as I just used a simple file to sharpen. I finally started just using the ones you find on Amazon or eBay. You can usually find those for a few $$$

  • DIY Pelican 1050 Bluetooth Speaker Dayton Audio

    Not sure what happened, I looked at the contest and it was no longer there. I contacted support and they never gave me an answer on how it disappeared, so I had to re-enter the contest. Then I got an email from support telling me, your project is in fact posted and good luck. I am as confused as you. But I’ve been away from instructables for a good year, and I’ve noticed they have changed allot. Kinda sucks my instructable got taken off, I missed out on all those votes. Hopefully it didn’t hurt my chances....

  • Step 2 has a picture of the Pictorial Schematics. Unfortunately, I am in no way a professional when it comes to Schematics. I think this might have been my 5th or 6th project. I typically draw out the parts and how I plan on connecting them.

And I use them Daily on certain projects.I would never ever(NEVER EVER) cover anything up, I have absolutely NOTHING to hide. Not sure why you would get that impression of me. I try and make sure I leave even my mistakes in my videos and tutorials, so people know when I make a mistake. The actual plan at the time was to have a showdown of welders. I have made these welders in just about everyway I could think of, except the China Circuit I have seen showing up here and there. A 6ohm 50-watt resistor will take 18 volts from a .6F capacitor all day long and not break a sweat. It never gets a smidgen warm. The SCR, is only powering a .6F cap at 18V at the most. Both the resistor and the SCR can handle all the way up to 2F easily! The only heat generated is by the leads and the Cap itself, if you discharge to fast and do not wait in between welds. If you check the other Youtubers Video's I mentioned. You will also see they have had no issues using the same components. It doesn't take to much energy to create a clean weld. believe or not?The reason I chose to make a low voltage welder, was to show I could. There is no actual reasoning, this is DIY and every once and awhile you see something and want to try building it for yourself. Not every DIY is for something intentional. Sometimes, you just feel like doing something. If you check my Google+ profile, you will see other welders I have completed. I plan on releasing those videos as time permits. With the plan on doing the caparison Video as soon as I finish my 7th and 8th welder(both low powered)But again, I do value you feedback and I can't wait to see your Capacitor welder when it is done! I will add you here on Instructables! Thanks for your comments!

I OCD research every little part and piece. Newbie here!! The person I got the idea for the old APC UPS case, used a Hockey Puck Style for his and he gets pretty close to the same results. I think he even got one of those fake 2F caps, that's actually only 0.6-0.4F also. He uses a LM317 psu and the APC transformer to power his. The guys I got the idea of using Buck and Boost Converter uses the same 100amp SCR. But he has since upgraded his system to a bigger meaner machine. Both guys used the same type of system with the same result. I wasn't sure if I could post the link to both video's, but I posted both names to look up. They both have some really great content on Capacitor welders.What I have found with the Capacitor welder, and this might be because of its small Capacity. I can only do the Pure Nickel Strip at about 0.15mm x 0.08MM Safley(or to my personal standard and I am picky). If I try Nickel Plate, it sticks and it normally sticks great, I am just not 100% confident so I don't even bother using it anymore(it works great with my other welders). If I find, I need a thicker piece for amp draw, I will just double up the strip and go over it 2 times. or I lay a bead of solder across the strip and then add the second strip(not sure if this right, but it works?).Currently, I am in the middle of a smaller PowerWall and it takes up a lot of my time. But while I test Batteries, I try and catch up on my videos(1 year worth) I also have 2 other welders I am planning. both very small and both very powerful. Hopefully as soon as I finish this powerwall.Thanks again for the comments and Thanks for taking a second look! I really really appreciate it!

    I apologize, I am in no way an Electrician. If you look at the Schematic/Pictorial I created. You will see a blown up written out picture of the CSR. It is connected by a 3.7V battery, a resistor to keep the amps below 150mA and a Momentary Button. Power from the cap is released when the Monetary button is pressed. Because there is no longer power after the press/weld, the CSR closes.

  • I have written both types, but I never really knew what I should call this version. I know with Circuits, I would draw out a schematic and with a Build like this, I would simply add smaller Pictures to represent the component used. I always thought a Pictorial was a little more detailed. I noticed most DIYer would just simply call theirs a schematic also, and I figured I would just do the same. To me, it was not quite a pictorial, and Not quite a schematic.Thanks for the comment.

  • Are you looking for a US seller? I will take a peek at my purchases from 2017 and see if that seller is still selling the 2 boards. I'll post them here once I find the links.

    There is only one Power supply that supplies a voltage of 24V 6-9amps. Then it is directed to a Boost Converter that boosts the supply voltage to the desired voltage. If you need voltage smaller then 24V, you can flip the 2p2t switch on the top of the unit and use the DC jack. With the DC jack, you can plug in any voltage as long as it is above 8 volts. If You have a battery pack and what to take the small supply on the go, you could also use the DC jack as long as you have the correct adapters. I have a Few XT60 to DC jacks I like to use.Schematics are in the video, and Step 2 has the Schematics also(see pictures).Thanks for commenting!

    Been playing around with some transistors and temp sensors. I just haven't the skill set to make the circuits, but I have been researching. I have built a few of the PWM controllers but found at my current level of experience. It far cheaper to just use a Buck converter with Potentiometer(1$). I have a circuit board I created with JLpcb, that works pretty good I might start using. I just built a Dremel where I played around with a few different designs, but ended up deciding against it. I learned to allot with that project.(I didn't post the experiments in the video, out of embarrassment)...LOL. I am sure as I keep building these, I will get to a point when I use PWMs and Temp sensing.I actually didn't even think about the shorting? I believe the Boost converter has some protection agains…

I am sure as I keep building these, I will get to a point when I use PWMs and Temp sensing.I actually didn't even think about the shorting? I believe the Boost converter has some protection against shorting, but from what I hear it can still blow mofset if you don't watch the connections(Using a diode to prevent some of this). I have The other type(plastic looking red and black). I might just swap them out for saftey reason. Thanks for bringing that to my attention! I was to caught up in the look..LOLI don't seem to have any issue with the EMI like the other guy mentions, but if you look at his other comments, he seems to have commented the same way on other posts, other than mine. Guess this is something he worries about. The Power supply has some filtering(I believe) to help prevent this.If there is any EMI spilling, it is so small, it would never cause any issues anywhere. I use a cordless phone plugged in right next to this.(don't have a way to measure yet, but looking for something I can afford). Love your Idea on the shielding!I still feel pretty safe about the build. The Main 24V Power supply is earthed and fused.The Boost converter also comes with its own set of fuses.(the AC side is Earthed and Isolated from all DC connection) All connection are isolated with shrinkwrap and HotGlue, some area with both..LOL I also used New Silicone wire, instead of used. I really feel confident its a safe machine.Thank for the comment and the compliments! Thanks for the constructive Feedback. I will definitely look into changing out the Banana plugs. I have allot more I will be posting here, once I get a chance. Please take a peek and if you see any way I could better the design, or maybe you see something I am doing wrong. Please comment. I am fairly new and Still learning, with each build. I have learned mostly from watching Youtube Videos and Instructables. Hoping to pass along some of the stuff I have learned(from trial and error) to other. This Build is actually one of my simplest and easiest to build. Thanks again for the Constructive Feedback and suggestions!

    Thanks for your Opinion. Come on man?? I just built a DIY Power supply, that I feel is safe enough to use on my 42V Battery Pack. I was very proud of the way it came out and felt it work Great for my needs. I also was very proud of the way it looked.. Just sharing with all who are willing to view and who are interested. I would never, ever build something I don't feel is safe, and I can assure you I would never ever put my family in that type of danger. If you don't feel this is safe for you needs, then you can move on and find another project at your level.

    You are correct. I like to use this on anything I make, where you will be looking through to see the components.This is why I will use wood for the outside or Frame. Then I try to make sure there is a support other than the frame, so when I plug and unplug the banana plugs, it stays sturdy. On this unit, It is also using the plastic lid as a stabilizer of sorts. I like to use the thicker stuff when I am building a box and the plexiglass is the only stabilizer. I wasn't sure of the name, the reason I called it plexiglass. Was just some leftovers from an older project. Thank for the FYI!Don't get me wrong, this may not be the best way of doing this. But it seems to work on this particular project.

    Thanks again for the tips! On my next project, I may play around with the PMMA. I haven't ran into the issues you mentioned yet. But I have only been doing this for under a year. My First project used the Lexan and it has held up pretty well(hacked, bench PSU from a computer PSU). For me, it just seems to cut easy, bend when I heat it pretty well. When I cut it to size, I just use a Plexiglass cutter and sometimes a sharp knife. Then I snap it on a straight surface. I use a dremel on the small square cutouts. My only gripe-If you don't have a sharp drill bit, I have seen it crack all the across what I was working on, destroying all my work. Until I discovered step bits. Now I haven't really had this issue. I guess I just like the cheaper price compared to plexiglass(newbie and learning). …

    Both Power supplies(24v and Boost converter) are pretty good at EMI, and Both have protection in place. I am not 100% sure how they are built, but I have never had any type of interference with any equipment I use. This actually sits 2-3 feet from our living room tv, Internet, Wireless telephones and Bluetooth Speaker system. Never had any issues. I am sure the people that designed both components accounted for this. If you feel this may be a problem, you can always add filters. When it comes to wood and flammability.If you take the time to make sure all connections are Isolated, and only use for its intention. You shouldn't have anything to worry about.

Where More electricity is flowing through them then this simple little charger. Soldering and Isolating the wiring safely, and I doubt you would ever have an issue. That don't mean you won't. Nobody can predict this. I just feel safer knowing I personally took my time to put together, than purchasing a plastic charger from a store. But again, I am no expert and this is just my personal opinion. But nothing is 100% safe, and with all electronics, you run the same risks.Electricity is no Joke and should never be taken lightly.Thanks for your comments!
