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!

  • Ground has nothing to do light output - on mains power that is.If running on battery power "ground" would usually be negative.In case you are dealing with mains power I strongly suggest to have the lamp checked by someone qualified ;)

  • You're right of course, this is only for mains power.But as said I think the easiest way is by using an exit pipe, or add a piece with bigger diameter.

  • Really cheap tools with just two power settings actully use a DC motor.A bridge rectifier gives the full power and a single diode in front of give about half the power.A switch bridges the single diode to go between full and low power.

  • Bad idea as the motor not only needs to work harder but also has a much higher chance to overheat.If anything then an exit tube with a much greater diameter will reduce the airflow properly without any changes or ill effects to the motor.

  • What you really need is a proper charging circuit - these batteries don't like being charged just with DC till full ;)

    Just ask yourself why people invented battery chargers and why you get specific ones for the various types of batteries out there ;)You did not mention the use for the batteries either so maybe it would be easier to get a 7.2V RC battery pack and the corresponding charger for it?

  • X96 (S905x) Android TV Box - Updating the Firmware and Costom Roms

    So we are not actually taking about the capabilities of the box but in fact about what videos/streams Kodi can play??If so then you might have missed the fact that Kodi does not really care about the hardware/firmware used but instead rely on the proper implementation of codec support - both from the hardware and the firmware.So instead of "messing" with the firmware it would be a better option to look for a media player that works with the files that trouble you.SMPC might be an alternative, same for the Kodi that comes with the firmware - as it is not the normal version from the Playstore.

  • If you only need to check for the presence of an object without identifying it or checking for material: Go optical ;)For example by getting some cheap optical mice and salvage their sensors.Of course you can also try a simple photo resistor if you play in normal light conditions.In either case you can detect the change and use electronics to create the output you want from there.With conductive tape, fabric or similar you always have the problem of actually getting enough change (or weight) to make them work reliable.As a really simple solution you could also make a shallow box and use plates on soft springs with micro switches to detect if something was placed on the area in question....

  • For USB the voltage will stay so no way of doing it this. Windows does not offer system event sounds for this task either although in theory it should be possible to create one with advanced skills - which I don't have. On a Macintosh you get sound events for this though. Can't really think of a filemanager with support for this either. Often requested by Windows users since XP times but MS never implemented a fix for it.

    Cheapest option would be Google Cardboard with the video signal coming from a live stream.Have not checked if the app supports a local media server with live streams though but should be possible work around that if required by using VLC or similar.As long as you can do with a sligh lag it should work just fine.For true 3D vision without noticable lack you will have to pay a lot of money, like for a pair of VR goggles.If you are goo with tools and making stuff you can also get two small LCD screens with HDMI input and use one cable for each screen.If small enough you can incorporate the Google cardboard design for the screen.Maybe something like this:http://www.ebay.com.au/itm/Small-LCD-kit-For-Raspb...

  • If you want to use a drill like this then you must be quite desperate.Sounds like a quick way to wreck the drill too...Just make a crank shaft that pulls on a plate and with a motor that is mounted on another plate - thick playwood should do.Place the tube from some old car tyre between the plates and let the motor run.You don't need a long crank, a cm or two is more than enough, like from some old lawnmover engine.The pressure in the tube gives the support for the weight of the concrete and you can adjust it to the load and usable movement of the crank shaft.At least this way the drill will only work as a direct drive and stay without cracked bearings - if you have a solid mount for the bottom plate with the crank and motor mounted...

    Certainly looks like one to me.You are already running on a late firmware so the updater might think the device does not need it.There are two way you can try to get around this:a) Do a factory reset and right after try to install the new firmware.b) Remove the first two lines in the updater script - they do the compatibility check and if failed give the Error 7 message.

    You wouldn't have tried other roms before, like something for a totally different TV box?Are you certain it is a X96 - e.g.: checked the device info page or used Aida to confirm?If the device really is what you say the firmware should install without any problems at all.

  • Unless they are fully electronic ballasts there is nothing of much use in them.Only the older ones use copper wire on the transformer, the newer ones cheap aluminium - so scrap value is relative here.The electronic ones have some nice parts in them but making an inverter from it might not work at all.If you have no clue yet anyway then just sell them make some bucks from it to use on something else.A serious grower has no problem getting lamps quite cheap, the ballst however is always the costly part, well apart from the power bill of using them.... ;)

    If it were that easy to update the playstore on chinese roms I would have included the latest version ;)You need the framework, GMS core and then some - all in the matching version number and installed correctly with the sme app name as on the box.Trust me it's a nightmare...If you do need the latest Google stuff I recommend using my naked rom that I made for this purpose.And using the normal ARM version would help too - having a 74bit CPU does not mean you also have a 64bit OS ;)You can always just download NFS from APKMIRROR, latest version should be2.3.6 (3544)...If that fails as well the game might not be compatible or require additional apps from Google, like Play Games.

    I know it is an old topic now but since someone found it I will add my 5 cents to it as well...When I had to do this I had no table saw, no circular saw either, just a jjigsaw, so I will base it on that as a tablesaw would be far too easy to use for this ;)Tools required:Electric jigsaw An U-channel long enough to hold your pipe - I made it from planks of woodPermanent markerCutout piece of pipe to use as a guide to slide along with the markerPreperations:It is best to have the U-channel the same length as your pipe.Otherwise you need to move and fix the pipe several times and that should avoided if you need a really straigth cut.The height of the side walls should be flush with the diameter of the pipe - or in lame mans words: put something flat over it with the pipe in it and there should be little to no gap.If the pipe diameter is more than the width of your jigsaw table need to add something so the saw won't drop onto the pipe.It is best to include some form of guide rails, let me explain:The jigsaw should rest right on the center line of the pipe.If you jigsaw has a support arm that can be adjusted use this.Otherwise add some wood on the sidewalls of your U-channel so the saw has little play and the blade is dead center on the pipe.In most cases the blade will be too long and hit the bottom of smaller pipes.Either buy a short blade or simply put yours into a vice and break the bottom bit of - don't go too short though!Optional: Use a cutout from the pipe to use as a guide to mark where you are cutting.This is optional as with a proper channel fit and some non slip mat you should be able to cut without it.Cutting a single cut:If you just want to open the pipe lengthwise you can now secure the pipe and slide your jigsaw along.Try not to stop and better move slow than trying to force your way through.To stop the bad vibrations simply press on the cut part behind the saw with your had - gloves highly recommended!Cutting a section out:Now, this is the real deal and before you try this on a long piece use some waste to train once or twice.Unlike a single cut you would end up with a lot of wobble and twisting if you just add another full cut.To avoid this I recommend to leave uncut sections every 30-50cm.This will keep the pipe round and stable enough to do what you need.Downside is that you need to drill a few holes along your cut line and use the drill to make at least one slot for every second hole - to fit the blade of the saw back into the pipe.The standing sections don't need to be long, about 5mm will do it.Now make your cuts and leave the 5mm sections standing until all cuts are done.Double check that you did not miss a cut ;)Put some tape around the pipe in several section to prevent vibration for the last step - make sure not to cover any of the sections you need to cut.Remove the 5mm bits with a final cut of the saw or on a hot day by using a sharp cutter knife.As an alternative you can also try a sheetmetal nibbler!They are available for cheap to be used on your electric drill.Although they are designed for thinner material they often cope very well with the thicker PVC pipe (only standard, not high pressure pipe!).Good thing about the nibbler is that you can cut along a line with ease and without the need for complex rails and guides.All you need is a steady hand because the direction of the cut is only affected when you twist the drill.It is also really easy to make complex cutouts this way, like for inserting a smaller pipe or making a flap for easy access to remove a blockage.

  • For max volume on this setup you need close to 1kWh coming from a 24V battery - that is without the voltage breaking down with the charge going lower.Would have been better to select an ampd that runs on 12V.Still easier to build a generator with an old lawm mover and alternator, and cheaper too.Batteries must be huge and deep cycle, so nothing on the cheap for this kind of power.

  • If it is not a level problem then I would assume the headphone output to be faulty.AFAIK there are no switches or buttons to activate the output, so if you have access to an oscilloscope I would suggest to use it on the output.That way you can confirm if something is coming out and at what level.Considering even at standard line level headphones should produce some sound you might still need a proper check of the amplifier.

  • Did you try the obvious already?Test the headphones in some other device...Trying a different headset in the amp...Making sure the headphones are plugged in fully...If the amp goes silent when headphones are plugged in it means the switch in the plug is working.Does not say anything about the headphone or the actual output to it though....

  • Downunder35m commented on RionZion's forum topic small 12v heater element control2 months ago

    Not much to explain really:The heater needs 10 amps, the batteries deliver a max of 3 amps - without the missing 7 the batteries will be in a short circuit and fail within a few seconds.Even if you have batteries that can deliver 10 amps they would not run for long.To run your heater at full capacity you need 10 amps, to run it for 2 hours the battery needs to provide 20AH at least.Of course you could limit the power requirements of the heater for example by using two or more in series but it would be far easier to build one to match.Still leaves the question of usability and run time on batteries.

  • I had that slipping problem with an extra large but also extra cheap clamp.Before you start messing with it please confirm:A) The notches on the bar are still present and not "flattened" - meaning the small cuts are not pressed together.B) The movable part of the clamp has not too much play!The A bit is usually not too important as the notches only offer additional resistance.If in doubt a slight cleaning with a sawblade will fix worn bits and you don't have to go deep - just very straight.Part B is where things get interesting as it needs to sit on the bar at very close to a 90° angle.If this part becomes "droopy" there won't be enough friction to hold it in place.Also, once tightened on an object the angle becomes even worse.If you want to find a suitable fix f...

    Did you extract the contents of the downloaded RAR archive to the SD or just the two zip files?Without a recovery it won't do anything ;)

    Well, it will istall automatically once you started it in TWRP - there is no fully automated update available.Select the firmware zip, add the gapps zip and let it flash - done.If not done or no gapps to find after then simply reboot into recovery and only flash the gapps again.

    Does not really matter, what matters is cleaning the wires and having a suitable tip on the iron.First "wet" the wires with the solder, to do so it must be really hot.Once you got a good solder layer on the wires they will solder with no problems to the plug.
