I like to improve myself and things I find :) Learning new things every day is next to impossible but I still try - only a working brain can work. I have no special sector to cover, electronics, electrical stuff, 3D printing, restoring old clocks and furniture. Whatever sounds interesting I try it. In my spare time I love to fly big kites, go fishing or simply go bush in 4WD to find a good fishing spot. Active spam fighter!

    If in doubt check turbo timers.Same thing in green, they keep the engine running to make sure your race home won't kill the turbo from overheating if you turn the engine off too soon.Some are dirt cheap and not really more than a simple timer "relay" o bridge the ignition.If you want to keep a relay alive for long that is soldered onto such a device than simply add a normal 12V relay at the output.So instead of switching the load directly you only switch another relay on and if that fails you replace it in minutes without soldering.

    1. Try a different browser.2. Check your browser settings.3. If still no luck wait for a reply from the code monkeys.When you click on the YOU thingy next to the PUBLISH button on the top of the page you should see your Instructables, Drafts and all in the pull down menu.A click will bring you to the destination.If that does not work or nothing shows up I do suspect a bug, assuming you tried the above.For me all is working fine here so at this stage I have to assume the problem to be on your end somewhere.

    Plastic Bottle Mosquito Trap

    Love the idea but sadly only found this Ible at the end of summer...Have to try it next time I manage to go fishing though.A thing about the yeast:Dry yeast requires luke warm water to "activate" the cells, in cold water it takes really long and too hot water will damage the cultures.Apart from the water yeast also needs something to eat, here in AU we can get Vegemite, it is based on dead yeast as the main ingredient.A tiny bit of this and half a teaspoon of sugar will make the yeast very happy and productive.A byprodut is alcohol and once the concentration is too high the yeast dies off and the fermentation stops.This takes about two to three weeks depending on temperatures.Good thing about yeast is that always new cells are produced and some of them tolerate heat and higher...see more »Love the idea but sadly only found this Ible at the end of summer...Have to try it next time I manage to go fishing though.A thing about the yeast:Dry yeast requires luke warm water to "activate" the cells, in cold water it takes really long and too hot water will damage the cultures.Apart from the water yeast also needs something to eat, here in AU we can get Vegemite, it is based on dead yeast as the main ingredient.A tiny bit of this and half a teaspoon of sugar will make the yeast very happy and productive.A byprodut is alcohol and once the concentration is too high the yeast dies off and the fermentation stops.This takes about two to three weeks depending on temperatures.Good thing about yeast is that always new cells are produced and some of them tolerate heat and higher alcohol levels better.So if you would add a tap or clamped rubber hose youcould partially empty the trap and just fill up again with a mix of water and sugar.This way the same trap can be used throughout the entire summer.

  • Earth connection is pretty obvious to see by the marking.Leaves only 3 more to try for 2 wires, I suggest using a multimeter.

    But you do realise the motor is rated for 25A and would require a heavy duty outlet and more than a standard 16A circuit breaker?At least if I am reading the text on the pic correctly...Usually not the kind of thing you connect to a standard power cord.And with no testing equippment nor knowledge how to use it I can only recommend to take it to someone who knows.No point in you risking life or a fire by connecting unsuited cables or plugs to this beast.

    Try rubber mounts for vibrating machine parts ;)You know simple stuff like these for example:http://www.tcbroschoppers.com/media/catalog/produc...Gives you a sturdy mount on the board while keeping shocks and vibrations low.Available in many different sizes, lengths and with harder or softer rubber.If you have any indstrial supply stores around you can check them and get a feel for the rubber before buying.

    After looking at some of you "insane" guys on Youtube I think you need something better.Hoping you have good imagination I go without pics as I am really bad at hand drawings.Instead of a board mount your (skateboard) trailer axles onto an open frame.In each corner of said frame you mount strong springs, like those on discarded trampolines.The springs hold the plate for your equippment.Tricky part is getting it right in size for your needs and to find strong springs that are short enough.But this way the tiny surface area where the springs hold the plate will eliminate all high pitched vibrations, the springs must be under enough tension to slightly expand.Like that the spring takes out lower pitched vibrations and small bumps.Mount the equippment with soft dampeners as liked ...see more »After looking at some of you "insane" guys on Youtube I think you need something better.Hoping you have good imagination I go without pics as I am really bad at hand drawings.Instead of a board mount your (skateboard) trailer axles onto an open frame.In each corner of said frame you mount strong springs, like those on discarded trampolines.The springs hold the plate for your equippment.Tricky part is getting it right in size for your needs and to find strong springs that are short enough.But this way the tiny surface area where the springs hold the plate will eliminate all high pitched vibrations, the springs must be under enough tension to slightly expand.Like that the spring takes out lower pitched vibrations and small bumps.Mount the equippment with soft dampeners as liked above and you should be fine.

  • Hint:These things are actually compressed carbon dust and they use a binder.They also love to soak up the electrolyte from the battery.For serious applications I suggest to use a good blow torch on them first to get them to a nice red glow.Doing so burns out all unwanted stuff that would otherwise contaminate whatever you use for the reaction.Since the caps get lost in process I used stainless steel wire to hold them.A great alternative for small scale are the carbon brushes you get as cheap replacements for drills and other things on Ebay.And as you said titanium is always a good choice.

  • I don't think as I don't have the information required to tell you which one is better suited for your needs.

    That's where the datasheets come into place.Also keep in mind that the best efficiency is not always throughout the entire range of regulation.

    I mean they both do what they should, so IMHO it all depends on your usage and needs.Since you use an ATX an no batteries I guess it does not really matter much either way.

    Why not check some images online or visit your local museum?Should be simple enough to find some examples how this was done before we had computer.And if accuracy is no real demand anyway why not use belts and pulleys?Much easier than gears.The info on the rotation speeds can be found through Google and Wiki.Check how long the planets need to get around the sun - this gives you the ratios.Same story for their moons just base it on the speed of the planet instead of the sun.

    Not the best idead to use this as a first project if you have no clue about gears, how to make or how to use them correctly.Start making your own gears and simple mechanisms before attempting to copy the solar system.If you want it to be precise then you either need to do proper research and buy the required gears or you have to make them yourself - both requires decent understanding of what you are doing.

    Well, best option would be to do a proper pressure test and to check for leaks, if present then fix them.There is little to no chance for any detection system to decide if a slow leak is a leak or actual water usage.Did you check the pressure in the expansion tank that is connected to the pump?Quite possible there is no leak but a faulty expansion tank - or one that is too small for your application....

    Be aware that welding cables are often 10mm² and more.Even if you add short and thick cable with proper welding attachments the coil in the transformer will still heat up quickly.You can almost imagine it like the wire in a fuse at home - the cables after it are much thicker making it blow when the current goes too high.When I played with MOTs for welding I got enough of the troubles and welded two coers together after removing the crossbar.This way I had enough room for a few decent layers of thick cable.Don't remember the thickness but it had quite thin insulation and was a very thight fit to get into the core.Ended up with just 5 turns but was enough for half decent spot welding.

  • Hmmm....That these questions for downloading PDF's and getting a short term membership made me wonder.Paylpal is being used almost everywhere these days, I think some people would actually value an option to just download one or a few PDF's at a bargain price.Comparing the pricing for membership I think something we call a "gold coin donation" in AU would be nice.Pay a dollar or two by Paypal and in return get the PDF of the Ible delivered to your inbox.

  • Nice piece of info on the Toshiba drive!But I would like to add something for hard drives in general:It is next to impossible to produce the actual disks totally error free.The higher the capacity per disk given the material is the same the higher the standard rate of errors.This is as true today as it was at the times when a 100mb drive was something to consider if you already had enough cars in your garage.The controller stores not only info on the physical stuff in terms of drive and sector layout but also about the status of drive (disk) areas.So not only your data is there but also info on the health status.These days all drives come formatted at a low level and already tested.So all existing bad sector and similar are already written off so to say.Your check software takes this in...see more »Nice piece of info on the Toshiba drive!But I would like to add something for hard drives in general:It is next to impossible to produce the actual disks totally error free.The higher the capacity per disk given the material is the same the higher the standard rate of errors.This is as true today as it was at the times when a 100mb drive was something to consider if you already had enough cars in your garage.The controller stores not only info on the physical stuff in terms of drive and sector layout but also about the status of drive (disk) areas.So not only your data is there but also info on the health status.These days all drives come formatted at a low level and already tested.So all existing bad sector and similar are already written off so to say.Your check software takes this into consideration if it was synced by the manufacturer with a corresponding signature to read on the drive.Meaning bad sectors from the time of productions should not show up.Sadly this information often gets lost or is simply not added onto the drive during the preformatting and testing.So even on a brand new drive you can see a bunch of errors.Some programs allow you to hide the errors found so at the next start you will only see new problems and would have to enable the old errors to them - very helpful feature if you have it.To make it very short:Either way track the bad sectors, if in doubt use screenshots and compare them if you are notified there are more.One or two every few months on a drive that has daily use is no big deal and can be considered aging.If problems accumulate in close areas or the numbers increase drastically it is time to act on your backup strategy and to prepare a new drive.The old drive as said can be checked again after a low level format.There are free tools that do the testing for you by filling drive with bogus and then reading if the bogus still makes sense - if not bad sectors are reported back.The first run will show quite a few and if they keep increasing after each run the drive is done and dusted.If after 3 or 4 tests no new errors show up you can risk using the drive for uncritial stuff like storing movies for your home cinema that already have a backup.

    Those things are like lamps and should have a screw going through to hold it all together.If you can turn the pieces there must be a screw.Often hidden in the base and covered with some felt.

    This way the transformers are connected parallel.I would prefer aniti-parallel, meaning one blue and brown should be switched.But with the wire size on the output you will have a hard time welding.And of course these output ables should be as short as possible, you simply can't use 1.5 or two meters as the voltage drop would be too great and the cable overheats.

  • Problems with some sectors on a HDD are quite common.The drive will take care of it.Proper backups of vital data are essential anyway, so do it ;)To keep track of the status just run the tool once ever three months and write down how many problems there are.Once they start to increases drastically in numbers consider replacing the drive.A short term fix after this for a bit more use can be to do a low level format.Follow up with a complete disk check after formatting into the file system you need.If lucky the "dead" drive will work for another 6 to 12 month before the errors atart to accumulate again.

  • Low tech:Wire or strong cord on pillars connected to a switch.Using flexible pillars like silicone or rubber would be prefered.Works similar to these wire shut offs on big machines.High tech:Use parking sensors and set the alarm to a really short distance.Once alarm is activated the corresponding gear is blocked and only the other direction will work - simple enough with two relays.

    Calculate the resistance of halogen light bars as used in work lights and such.As an alternative you can use heating elements as well.Cheaper and more reliable than normal resistors in this power range.

  • There are two problems with a lot of questions:a) The user never comes back after asking because he found the answer himself or elsewhere.b) The user does come back until he has all the info he needs and then disappears.I think a slightly better way of removing those wastelands would be to move all questions into an archive section if the user did not come back or mark it as answered within a certain time.No point trying to answer topics that will never be seen by the one person who could mark it and select the best answer.

  • Yes, the capacitors are for the ripple, these step up converters produce quite a bit of it, sometimes you also need an inductivity to eliminate them fully.You will find out for sure if there is unwanted noise during RX/TX.The mains charger is most likely designed to charge at this rate.In a car the drive time is often short so they try to charge as fast as possible.Also possible that it hs two inputs for charging that are different.

  • If you need to go solar then the best and only way is to match all voltages to the solar system.So instead of a fancy, battery powered radio take a standard car version and make sure you can adjust the output power - comes in handy if you really need to conserve energy and the distance is not too far.Like that you only need a 12V solar panel, 12V solar charge controller and a 12V deep cycle battery.If the normal drain voltage of the battery is too low for the UHF to operate properly than you can still add step up converter set to 14V and a few nice sized capacitors to prevent unwanted interference.The size of the panel depends on the battery size and how much real sunlight you get in a single day.You want the battery big enough to make it through 3 days without charge and the panel(s) b...see more »If you need to go solar then the best and only way is to match all voltages to the solar system.So instead of a fancy, battery powered radio take a standard car version and make sure you can adjust the output power - comes in handy if you really need to conserve energy and the distance is not too far.Like that you only need a 12V solar panel, 12V solar charge controller and a 12V deep cycle battery.If the normal drain voltage of the battery is too low for the UHF to operate properly than you can still add step up converter set to 14V and a few nice sized capacitors to prevent unwanted interference.The size of the panel depends on the battery size and how much real sunlight you get in a single day.You want the battery big enough to make it through 3 days without charge and the panel(s) big enough so they can fully charge the battery on a day with light clouds.

  • Problem is accuracy and feasability.Sensors for this type of accuracy exist but at a very high price.http://www.hamarlaser.com/index.php/systems/ultra-...Downside is that the more accuracy you need the shorter the distance needs to be.For example measuring a change of 10µm if a measuring distance of 4 or 5mm is required will be next to impossible.In this region physical measurements are usually the way to go.The actual gauges can still be digital though.Gauges like this can be used for all sorts of things, I used them to get my arrows straight....http://www.lapmaster.co.in/meas_precesion.html

    Knife Sharpening

    This depends on the knife and how it was sharpened.These steel rods are supposed to "refurbish" the edge of your knife.When cutting a lot with a very sharp knife the edge can become what I like to call twisted.Small areas where the edge is pushed away from the center line or in bad cases with tiny chips.The round steel is not reall capable of removing any great amounts of material but due to the hardness it acts like a polishing file.A fine blade with a 7-10° angle will certainly get some more cutting time out of this procedure but a utility knife used for everything that has a quite thick blade and an edge angle of more than 10° has very little to no benefit at all from it.IMHO a quick run on a fine stone every now and then while using the knife is a nicer option if y...see more »This depends on the knife and how it was sharpened.These steel rods are supposed to "refurbish" the edge of your knife.When cutting a lot with a very sharp knife the edge can become what I like to call twisted.Small areas where the edge is pushed away from the center line or in bad cases with tiny chips.The round steel is not reall capable of removing any great amounts of material but due to the hardness it acts like a polishing file.A fine blade with a 7-10° angle will certainly get some more cutting time out of this procedure but a utility knife used for everything that has a quite thick blade and an edge angle of more than 10° has very little to no benefit at all from it.IMHO a quick run on a fine stone every now and then while using the knife is a nicer option if you have the time for it.

    Temp depends on the insulation.Enamelled wire can tolerate about 150°C without problems, normal PVC insulation about 60°.And yes you need a suitable container but the oil is an insulator, so no electrical problem here.
