    Travel Door Lock

    If I traveled and stayed somewhere I expected someone to break into my room while I was in the room I believe I would have a far better method to keep them out. Anyone over 120 pounds could break that in about 5 seconds, then be in the room with me. That's when I would get worried.

    I don't understand why this is better than the fan you used. Since you said the fan worked but blew cold air in your face, why not just turn it around, like you did with this fan? I can get a desk fan for $10 and it won't make enough noise to spoil my music.

  • Glass Roof Pergola for Less Than £300!

    He didn't use glass. He used acrylic sheets. (plastic)

    Just being ornery I guess, but that isn't a pergola. A pergola is an canopy with trelliswork with the express purpose of growing trailing vines or flowers.

    I may have missed your source for the acrylic sheet. Even though you are in Scotland I'm curious since here in the US, 4 mm (.22 in.) acrylic sheet is going to cost about $6-$8 a square foot. Or $70-$80 a square meter. Which would make the cost of the acrylic about $500. And unless one is lucky it would have to be shipped which would likely add $100 to the cost. I checked and many home supply big box stores don't sell panels that size.

  • Listrik L585 AC DC Portable Power Supply / 158,000mAh Power Bank / 585Wh Solar Generator

    I know the right way to use periods and commas. And I don't confuse them, using one when I should have been using another. "... the word equivalent exist(s) for a reason...", but the problem is you just made up a reason. Means nothing to anyone but you. Like I said and many others have also said, use standard terms, don't make stuff up, be consistent and use ISO standards. You keep using junk you'll continue to get criticism and obviously you don't much like that. Technical articles are not prose, correctness is absolutely critical. By the way your construction techniques and expertise are really very good. Better than 99 out of a 100 hobbyist.

    LOL. I taught high school here in the U.S. Interesting that high school students in other parts of the world have the same attitude.

    Hmmm...every tablet, smartphone, hobby electric drones use soft shell lithium batteries. They seem pretty reliable to me.

    While you have done a good job illustrating your project when writing a scholarly article you should stick to industry standards not consumer made up flash. Also 585Wh/22.2 volts is 26.364 amps, mAh. Perhaps you meant to use a comma instead of a period. I know some countries use a period to mark the thousands, but you used commas elsewhere. Converting the capacity to 3.7V mAh equivalent is not industry standard, just a way to hype capacity. It's a 585 Wh battery and will provide different amounts of current for different voltages. But the same amount of power. While you are just copying the conversion it was conceived as a method to inflate and hide the true capacity of lithium batteries. Only used to hide the true capacity.

  • Power Your Soldering Iron With a Drill Battery!

    I don't think it is clear that this is not a power supply build. It is a battery protection circuit. Lithium batteries do not like to be discharged below a certain voltage, this circuit is to turn off the voltage to the soldering iron when the battery voltage reaches approx. 15 volts. Should be able to use it with any 20-volt lithium battery with just a modification to the contacts to the battery.

  • How to Convert Water Into Fuel by Building a DIY Oxyhydrogen Generator

    I'm not sure what was the purpose of that outburst. Critical mass simply means there is enough hydrogen to burn (oxidize) and enough oxygen to support the process. Put a lot of hydrogen in the presence of a lot of oxygen and it will produce a lot of energy and water as a by-product. As in a hydrogen burning automobile engine...or the Hindenburg. Except in the case of the Hindenburg I suspect most of the water was vaporized.

  • How to Make a DIY Awesome Heated Vest!

    You can't actually change the amount of current the heating pads draw, but to lower the current you might think about using a PWM voltage controller. It'll use less power and thus lower current since it pulses the voltage on and off. And of course, this will allow control of how warm the pads get. I suspect that's how the commercial jackets work.

    Very good instructable. I have some pads very close to the size of those used and when the voltage is 5 volts, they draw about 1400 ma. I checked. If used with 3.7 volt lion or lipo batteries the current will be at least twice that. This is likely why there are not many of these available commercially since one pad will run down one battery is less than an hour.

    Although there is little doubt that a bluetooth speaker of equal or better techniques could be bought much cheaper than this design, this is a good essay. The physical build techniques are well thought out and presented. The bluetooth connection can be used for other more esoteric projects. Kudo's for giving sources and links. Thumbs up!

While this may seem like a small point one cannot use sloppy words to define a concept. If someone wants to use hydrogen as a fuel, so be it. It'll be more expensive than gasoline, and likely not nearly as efficient. Whatever argument you want to use to counter my argument, whatever "new" chemistry you purport to use the whole business of making and using oxyhydrogen is fraudulent at it's core. It's like trying to name the ghosts that they look for on TV. Silly and Fraudulent. Everything about the topic is fraudulent so proponents use sloppy words and technique to try to disguise the truth.

You cannot invoke the name of God and mean anything other than one supreme being. Nor can you change the way compounds are created. Hydrogen will run a vehicle if the vehicle is tuned correctly. If the hydrogen is obtained independently of the vehicle. You cannot create hydrogen with a vehicle and use that hydrogen to propel the vehicle and get better fuel mileage. The vehicle necessarily must get worse fuel mileage. The vehicle will burn the hydrogen in the presence of oxygen and form what? WATER Heating the hydrogen and oxygen doesn't form water. The chemical process of burning hydrogen in the presence of oxygen does. There is no mixture of H2 and O2 in the process. Pure hydrogen burned or oxidized forms water. It's not hard, it is taught in about 8th or 9th grade Physical Science.

    This whole discussion is useless anyway, including my part. The problem is that HHO is a euphemism for Browns's gas. And Brown's gas is the hoax. Proven in a court of law. Proven by chemistry. Shown by common sense.

It cannot be made chemically. If made by measuring it is useless. HHO cannot represent this mixture since that is the chemical formula for the compound water. The use of this "mixture" as a fuel is a hoax. Wikipedia is written by citizens with no attempt by anyone to validate. It is not proof of anything.

It was made up by a person named Brown who was tried and convicted of fraud in the matter. You might want to check into the meaning of mixture and compound. Sand and water is a mixture. The sand is still there in the form of sand and the water is still there in the form of water. SiO2 is sand and H2O is water. Sometimes sand itself is a mixture of different compounds.

    That's the point. There is no such thing as a mixture HHO. There is a mixture of hydrogen and oxygen. And since both exist as binary molecules it would be H2 + O2, not HHO. It could be two parts hydrogen and 1 part oxygen, but that would just be by weight or volume or however you want to measure. When you write HHO you are actually saying a molecule of water. (A compound). So you say mixture and write compound. The only compound of HHO that exists is water, not some make believe gas fuel. It's a hoax.

    Most all clothes are treated with fire retardant so cotton balls are going to work better with less treatment.

    Cotton balls soaked in petroleum jelly work better and are much easier. I've tried both and dryer lint sometimes just doesn't burn well. Most clothes at least in the US are treated with fire retardant. Probably elsewhere as well since US clothes are seldom made in the US.

Also if the field is not prepared and very level and flat, the cultivation dept will vary. A truly autonomous tractor is many times harder to build than an autonomous car. The big 500 hp. tractors than pull 40-50 foot discs are not completely autonomous. They have an operator in the cab that makes small corrections. All the errors in a car can be corrected by optics and radar. Another thing to consider is that the GPS systems are either Russian or USA, and in both cases are subject to military priority. Any other country is using a GPS system they have no control over. Any system that is used in a small area would probably be easier to build and far more accurate using in field radar reflectors. There is actually no reason to use GPS for this device. A radar unit on the small tractor and several reflectors could be made with the accuracy of a fraction of the wavelength of the radar frequency. Very small error.

    With the compass you'll know which was is north, but without any history as you said, it is still lost. A compass can't tell where it is located. Without gps or a map (or history) the location is not known no matter how far one moves. The line the machine or you moves along could be anywhere. With a compass one has to know where one is to go where one wants.

    Hamblin, I can't see how a license would be needed. First in the US at least a person can build whatever they want, so long as they make no profit from it.Second this is NOT a new concept. There are large tractors used on corporate farms that do exactly the same thing with the same equipment. The only thing that might be licensed would be his code. And I doubt his code is completely original to him.

    "If you get lost in a thick jungle or underground car park you're stuffed!"With a compass or any sort you still have to know where you are in the jungle or garage in order to make use of said compass. Doesn't do much good to know where north is if you don't know which direction you need to travel!

    Hamblin, you might want to go smaller than 50 horsepower. A 50 horsepower tractor is a typical farm tractor. A small 15 hp lawnmower will spin its wheels pulling a small disc.

    I've made numerous battery packs from old laptop batteries. Some I've solder to several times. I use a little extra flux as well as scruff the end of the battery. Never had one fail. Heat can damage any battery, even lead acid, but it would take an obvious effort to get an 18650 hot enough to fail by soldering to it. I can pick the battery up with my hands immediately after I solder to it! I think the batteries sometimes fail and then they get hot. Not the other way around with a soldering iron.

    Skin cells are no big deal, what a person needs to watch out for are those brain cells that are dying off!!!

    90 percent of small drill bits are broken because of poor technique. Primarily not drilling straight. With small bits do not hold the handle of the drill. Use one hand to hold close to the chuck and the other to push down straight in line with the drill bit. It's very easy to bend and then snap the bit if holding the handle. Drills are very poorly designed, with the handle offset like they are. In metal a major reason for broken bits is a stuck bit. Try using lubricant and a proper speed. On bits below 1/8 in, get a chuck for and use a dremel type tool.

    Make a Ring by Melting Pennies.

    It would be a lot safer to use either discarded copper pipe or even buy a few feet of copper pipe. Or buy copper el fittings. They are cheap. Less that 50 cents in my area. 10 feet of 1/2" copper pipe is about $20. And no zinc oxide fumes. Don't use copper fittings that have been used as they probably were soldered together with lead solder. And the fumes from melting lead are worse than the zinc oxide.

    I had an out of work friend try that with quarters, half dollars and big dollar coins. Yes, infinite money, but only about 25 cents an hour profit. It takes a while to sort through $1000 dollars of coins to get maybe $1 worth of silver. Much less profit with pennies.

    It would actually spin less. Same amount of energy input, but some is used to charge the capacitors so less spin.

    I also like to make stuff and do. However there is not enough time in my lifetime for me to do the things I want, so I tend to buy things that are cost effective. I have to decide what I'm going to learn or make and just let the others go. Or buy and be an appliance operator.

    ESP8266 WiFi Analyzer

    I see the 32 CYN price. That screen can't be bought for $5 in the US, or likely anywhere outside of China.

    On AliExpress that particular display is a little less than $14.00 delivery to US. Makes the project in US about $25. Cheaper than I thought. I yield.

    Your kind of hard headed. I noted the CNY price and the site also had the USD price printed. I quoted USD prices. To repeat that color LCD screen cost $32 dollars US money.

    Well it is an interesting project. Good for learning, but I looked up the display on those sites you sent me. It was about 32 USD without the header. That would make the cost of your project for someone without the parts about 50 USD. Batteries, ESP8266, cables and miscellaneous parts. I found a Lenovo 7 inch Android tablet on the same site for a little over 46 USD. I may see if I can order from those sites from the US.The only reason I pursued this issue is that it is important to know what a project would cost if someone would like to try it. You likely had some parts on hand and didn't include them in your estimate. I

  • Ultimate Crosscut Sled With Dust Collection

    How does that dust collector work? There is no dust at that point.

    Beg all you want. :) Most of the dust from the table saw is underneath the top. Very few sleds have a vacuum in that position. My dust collector is from under the saw. With it off some saw dust does collect on the top, with it on very little. Now if you also have a second dust collector where most of the dust is then you're good. That dust collector in that position will collect only a small percentage of the dust. There is no way on God's green earth that dust collector in that position removed 90% of the dust from any cut. I can put a hose within an inch of the blade in front and it won't get that much of the dust. The spinning saw blade throws it down into the normal dust collection channel. Which is built into 99 % of all saws. If you are cross cutting a 12" panel th...

  • Giant Homemade 16" Disc Sander (for the Lathe)

    Before you build a 16" disc sander, you might want to check the difference between the price of 12" vs 16" disks. Unless you have the money to buy $15 vs $3 each disks.Also if you have a way to do it put a very slight convex shape on the sanding disk. And tilt the axis of the disk by the same amount. Much easier to get a flat sanded surface. Believe it or not. Only the part of the sanding disk that is at a right angle to the base plate will be sanding. But since it's turning the whole disc is used. There will also be far less tendency for the piece being sanded to catch and jerk out of you hand.

  • How to Drill Straight Holes Without a Drill Press

    I started to just let this go, but I wasn't talking nor commenting on metalworking processes beyond a hacksaw. I see there is a PRO by your avatar. Your statement is not correct.There are some machining techniques that work better without lubrication. Lubrication and cooling are not the same thing. Neither lubrication nor cooling aids in chip clearing. Lubrication requires a lubricant, cooling requires a coolant, and chip clearing usually requires pressurized air or flood coolant. I don't believe any of those are required with a hacksaw. LOLNone of these process are of much use when using a hacksaw. Unless you have super Pop-eye arms and you can run that hacksaw fast enough to get it hot. 50 years and I've never seen a hot one yet. Most hacksaw blades do not do well with oil ...

Unless you have super Pop-eye arms and you can run that hacksaw fast enough to get it hot. 50 years and I've never seen a hot one yet. Most hacksaw blades do not do well with oil for lubrication. Oil will not aid in chip clearance. There will be no chip clearing problem with a hack saw. Because the chips natural drop away. Chip clearing is required when machining a hole or cavity. Hard to do that with a hacksaw. Most machinists that use a metal cutting bandsaw, use them dry. One reason being with oil the chips will clog the cut. A metal cutting bandsaw is run slow to resist heat. Heat is what destroys tools and cutters. Oil will in fact cause chip buildup. What shortens the life of a blade or cutter is heat. Lubrication might ease the hack saw blade through the material, but it is not acting on the teeth of the hacksaw. That would be counterproductive. Making the teeth slicker, so they don't cut as well. All oil on a hacksaw will do is foul the cut and make a mess.

    There is not really any reason to lubricate a hack saw blade when cutting. Just makes a mess.

    Well I don't see you latest story. But go ahead a put oil on the hacksaw blade. It won't do much if any good...and it causes a mess. So far as making the blade last longer, I suspect any benefit there cost wise will be off set by the minute cost of the oil. Like I said, horizontal metal cutting band saws seldom use oil. It's just not needed for low speed cutting. I've cut 1 1/4in x 8 in steel without oil with a band saw and the cut looks really good. No heat buildup. The cut took about 20 minutes. (normal) On the other hand on my vertical mill I use some sort of lubrication and possibly coolant on any sort of metal.

    Acrylic is acrylic, but sometimes called plexiglass in the US.But hold on to your pocket book when you price a piece that thick. I found it at $40.00 a square foot plus shipping.

    Very good idea and great creativity.

    You might be able to find acrylic at a place that makes large aquariums. Plexiglas is the generic term for acrylic.Plexiglas is the Arkema brand name.

    Honestly I'm impressed with how much work you did, also with the level of craftsmanship. Your photos of the base showed how well you can fabricate. But that light while it's cute, doesn't work. And I really wish you would fix that carpet. Leave the knob on the foot, it can be operated by foot, but the light is almost useless at the foot. Cannot read by it.
