Can anyone help explain this strange chemical smell from our laundry room and basement?

We had discovered a very strange kind of chemical smell coming from our laundry room and the very same strong smell from the basement sort of linking toward the hot water tank. I had done laundry last night and started to smell it when I woke up the next morning. We are worried if it is something harmful. Could this be something from the hot water tank or something else? Please help!

HHO generator with iron electrodes

Hello Everyone, I recently found out about Sodium Hydroxide as an electrolyte. I have read that it does not affect the electrodes like salt or baking soda and it does not create any weird gasses like chlorine. The main reason for using stainless steel electrodes is to prevent this corrosion, but since sodium hydroxide does not create this corrosion, can I just use the much cheaper iron or regular steel as the electrode plates? Thanks in advance

This is how you can preserve food.

Echoing what the others say, it's all about "available water".Salt and sugar does the same thing - draw water away, or make the water too salty/sugary for bacteria to live in it.Things that change the acidity kind of does the same thing - they make the water inhospitable, so the bacteria can't live in it.You can also make a mix of the two, using a bit of vinegar and a bit of sugar.Drying something also takes away the water.This is what is done with jellies and jam and fruit preserve and a lot of other things - olives too.The only thing that's different from all of these only works on things that are sterile - you can cover the outside in something that's toxic.The toxic thing can be a mold, strangely enough - because the mold makes toxins to protect itself, so other bacteria and molds can't survive. But it means you have to cut the outside away when you want to use it, and then you can't leave it, because you've opened a door for bacteria and different molds to "enter".Camembert is like this - the outer layer is a living mold that kills everything else.The toxic thing can also be residue from smoke because the thin outer layer is toxic, the bacteria can't enter. We can take a big bite of it, though, because the layer is very thin, so there's not enough toxin to affect us.bacon and fish are often preserved like this

Solar LED strip using lgabc21865

I have 2 solar panels that were used to charge shed lights (2 x AA batteries from each panel). And some lgabc21865 lap top batteries. I'm curious what would be needed to run some 12v led strip lights instead of the poor lights that were originally there using the LG batteries. Or if the idea is even worth the trouble. I'm very new to electronics in this capacity of setting up batteries with BMS. But I feel like it would be a good starting point to learning and useful at the same time. I have seen many tutorials on setting up battery packs with the batteries, but nothing for charging with solar or outputting 12v. Everything seems to run 5v using the TP4056 and micro USB. Any advice or information would be super helpful.

Technology Makes Cheap Drinking Water from Air

INTRODUCTION:   How can we best apply basic technology to help the underprivileged and/or disaster-hit countries like Haiti? Daily hygiene and nourishment are among the top needs for disaster ridden regions!  Simply put, no water means no hygiene. The Romans understood that over two millennia ago and created their complexly beautiful aqueduct networks for handling both fresh and wastewater! Other ingenious water systems like “air wells” have been found in the city of Theodosia (cf: discovered in 1900 by Zibold, see Zibold’s Collectors/Dehumidifiers) dating back to Greco-Roman times during the Byzantine Empire. These were strictly passive systems that naturally dehumidified air, collecting its potable water in underground basins. All air, even in relatively dry desert regions, will precipitate or release its natural water content (initially in the form of vapor) through condensation when it hits its dew-point temperature and below. That means you “chill” it to an appropriate level that is anywhere from 5F to 50F below its current air temperature, depending upon how much water content (relative humidity) it has locally absorbed. The condensation of the water vapor releases its internal latent heat (reheating the cooled air) which must be constantly dissipated (absorbed by something) in order for water formation to steadily continue. So how do we dissipate this resultant vapor-heat and chill our air without any infrastructure or electricity, in an underprivileged or disaster-ridden region? We simply bury a long cast-iron or any metallic drain-pipe sufficiently underground where the temperature of the earth is naturally held to a constant at around 45F to 55F. That’s our “free” chiller gift from nature. One end of the pipe, Figure-1,  sticks out of the ground to suck-in local outside hot air, and the other end dumps cooled dry air and water into an underground cistern where it gets collected and is piped to the surface to both exhaust the cooled dry air and connect to a water pump. We need a hand operated water pump to lift up the water above ground, and we need an electric fan to constantly pump air through the ground-chilled piping system. We can even force the cooled piped air to exhaust into a tent-like structure where it provides air conditioning as an added bonus, but this adds the penalty of both power and the increased fan size necessary to drive our required airflow further into an enclosure! While this concept is not “passive” (requiring electricity to work) like those clever Byzantine air-wells, it will produce much more potable water and within a smaller volume than those elegantly passive historic devices. The electricity for our fan power requirements can be produced by any one of four ways using either “active” or “passive” techniques: 1) An active playground or bike-pedaling-person or oxen-driven mechanism-generator, 2) A passive windmill generator, 3) A passive solar energy collection system that directly generates electricity, or 4) A passive thermo-electric system that directly generates electricity using the Peltier effect, operating solely on temperature differences between the cell’s top and bottom surface (we jury-rig the cool pipe and hot ambient air to contact separate sides of the cell). Depending upon how much water is needed, the required air volume plus pipe length and diameter, together with the fan will be sized accordingly. We can also configure groups of parallel fan-driven air pipes that are radially fed into the cistern. The sizing of this underground network depends upon the ambient air’s local average temperature and relative humidity (how much water gets absorbed into the air) plus buried pipe depth and effective underground temperatures achieved. The basic concept is one where we “wring” water from air at some given humidity content. The higher its relative humidity the more water is recovered from the air. The air-wringing process simply chills the air as it scrubs along the cooled internal pipe surface until it starts to rain inside the pipe from condensation onto its surface. The condensation is like the dew that forms on car windows, grass or any cooled surface in the early morning, before the sun comes out and evaporates the dew back into the heating air. A further bonus is that our dew-formed water is naturally distilled and very clean. It is potable water ready to drink without the need for additional sterilizing agents. Of course, we must make sure that the interior piping and cistern network is biologically cleansed before burying it underground. The hand pump with its 10 to 15 foot extended piping to reach the underground cistern must also be cleansed. The beauty of this constantly replenishable water supply is its convenient underground installation anywhere! After the in-ground installation, we have a virtual, partially passive, no moving parts, non-breakdown system containing above ground total access to all moving parts that could breakdown, namely the water pump and electric fan. Also, it is easily maintained, with few moving parts (water hand-pump and electric fan) and basically lacking any technical complexity which makes it ideal for technologically backward regions. The example below uses a relatively small industrial fan moving air at 1500 CFM (Cubic Feet per Minute) with a DC motor rated at 1kW. This fan together with our underground piping system will conservatively generate 12 GPH (Gallons Per Hour) of potable drinking water without need for any purification chemistry. Based on an average electrical cost of 14-cents per kWh (kilo-Watt hour), the typical commercial distillation of one gallon of drinking water costs roughly 35-cents as compared to our cost of only 1.2-cents. Furthermore, if we decide to go green and use solar energy for generating our water, it would effectively cost us nothing beyond the initial installation! USING A PSYCHROMETRIC CHART TO SIZE OUR WATER SUPPLY: The following gets a little technical and is only provided for those die-hards who are truly interested in how the science works. Those non-technically schooled may skip this part and not miss the basic concept. Figure-2 shows a Psychrometric Chart for air. This chart summarizes some of the basic thermodynamic properties of air throughout its typical range of operating temperature. The chart uses six basic air properties that defines the physical chemistry of water evaporation into air:  (1) the enthalpy or total energy contained within a unit of air which is a combination of its internal and external energy, expressed as the amount of BTU-energy per unit mass of reference dry-air, (2) the specific volume or the ratio of a unit volume of local air to its mass of reference dry-air, (3) the humidity ratio or the amount (mass) of moisture in a local unit of air divided by its reference mass of dry-air, (4) the percent relative humidity per unit of local air, or the mass ratio (expressed in percentage form) of the partial pressure of water vapor in the air-water mixture to the saturated vapor pressure of water at those conditions (the relative humidity depends not only on air temperature but also on the pressure of the system of interest),  (5) the dry-bulb temperature or the locally measured air temperature, and (6) the wet-bulb temperature or saturation temperature which is the local air temperature experienced during constant water evaporation (a wet-bulb thermometer is typically used:   a thermometer that measures resultant temperature while wrapped in a water wet-gauze and spun to generate local air movement and max-evaporation)  1.0   The Process and A Sample Calculation Our Psychrometric Chart uses six thermodynamic properties that help to determine the amount of water available for extraction from the local ambient air as a function of its temperature, pressure and relative humidity.  Let’s assume the following local ambient conditions for the region we plan to construct our water system at:  (1) Typical daily air temperature Td = 106F and one atmosphere pressure assumed at sea-level, (2) Relative Humidity, RH = 55%, and (3) Typical underground temperature down at six feet is measured at Tu=55F (at 12ft. it drops to ~45F). This yields the following calculated results for obtaining a steady-state supply (changes at night) of water to fill the cistern:      1)      In our example, the “local” air (dry-bulb) temperature is Td=106F, at a relative humidity of RH= 55%.  Fig-2 indicates that the resultant Humidity Ratio is HR= 0.0253 Lbs-water/Lb-Dry-Air (intersection of Td=106F line and RH=55% line, then horizontal to HR value).  We then determine the “gulp” of air volume containing the HR Lbs-water which corresponds to the point of intersection of Td and RH. Interpolating on specific volume “mv” yields mv=14.7 ft3/Lb-Dry-Air (this value sets the optimum unit airflow for our given ambient conditions, and creates a ballpark pipe length to diameter ratio needed later). It represents the basic unit of air volume that will enter our underground pipe per given time, and ultimately defines the size of our fan and piping network. For increased water creation, multiples of this unit volume will scale up the additional amounts of water that can be collected. 2)      As the inlet air cools down to a temperature of Tu=55F, from contact with the relatively cold underground pipe, we follow the constant enthalpy line (red upward left-diagonal) from the intersection of Td and RH to its saturated air temperature condition of Ts= ~88F, which is its dew-point temperature where the corresponding local RH=100%.  At this temperature or under, the air precipitates and releases its moisture content, resulting in water condensation onto the pipe walls.  Since our air will chill to a final pipe temperature of Tu=~55F, we follow the RH=100% saturated curve (green) down to yield an HR=~0.009 Lbs-water/Lb-Dry-Air. This is how much water is left in the air when it gets to 55F.  Therefore for every pound of local outside air that enters the pipe, mw=0.0253 – 0.009 = 0.0163 pounds of absolute pure, distilled potable water precipitates onto the inside pipe wall (per pound of dry air that is cooled and dehydrated) to gravity-flow out the pipe exit and into the cistern. 3)      We now convert pounds of air per unit time into a unitized volumetric airflow that yields gallons of hygienically pure potable water production per unit time. For every Va=100 ft3 of local volumetric air movement per minute (CFM) through the pipe, which translates into ma=Va/mv= 100/14.7 = 6.8 lbs. of dry air per minute or 6.8 * 60 = 408 lbs. per hour (PPH), to yield a water-flow of mwf=ma * mw = 408 * 0.0163 = 6.65 PPH or 6.65/8.345 = 0.8 GPH of water.  An industrial fan rated at 1kW DC will typically move 1500 CFM at a pressure of 8-iwc, to continuously produce 15 * 0.8 = 12 GPH of pristine potable water. 4)      Not shown here are the design details of sizing our pipe, fan and solar collection system for electric power requirements using heat transfer principles coupled with a thermodynamic heat balance, and aerodynamic fan performance assessment. These details help to size the electric power generation requirements plus margin used to properly size a solar collector containing further margins for overcast days. The engineering involved here is straight forward but beyond the scope of the current project.

RC aircraft set up problems

Hi all,I am new to the world of RC aicraft, I have purchased 4 complete used (probably the wrong move) scratch built RC aircraft which have a variety of RXs and servos.The planes came with no TX, so I purchased a used but good (so I'm told) Sanwa RD8000 35Mhz TX (all of the RXs are 35mhz), I purchased a no.64 crystal (I could only get a Futaba one which I hope is the same) for the TX to match the RX crystals.I have programmed the TX the best I can keeping it simple, the problem is that when I switch on the TX the servos in the planes just either chatter or drive erraticly from end to end and seem to have a mind of their own.Any ideas ??Please note! I'm an old guy soplease be gentle with the terminology and technology.

Powering an Android Tablet without a battery?

So I bought my sister this Visual Land tablet about 2 years ago. Eventually both the mini usb and charging port broke off from the logic board as expected from a cheap product. So I have this nice idea of using the tablet as a car nav/entertainment system. simply get rid of the battery and push 5v via a standard cigarette light usb adapter or make one with some 5v regulators and done. I tried resoldering the charge port. I get 5.23v on random points on the board but I get 0v at the battery with the charging port connected. I pulled the battery and tested the terminals on the board with the charging port connected no battery, 0v at the board and the battery alone is also 0v most likely dead and trash as it sat for 1.5 years in a shoebox untouched. So I pulled out my homebuilt psu power supply and hooked up the variable output to the battery terminal on the logic board. When pushing 3.7v~ I can get the first splash screen to show up but the tablet shuts off right after. When pushing 3.8v any thing higher the first two splash screens show and android starts to boot but the tablet powers off soon after.. So i decided to risk it and pushed 5v directly to the board. It started up fine and booted into android normally except for the low battery issue and some heat coming from the processor. Maybe a heatsink and rigged laptop fan into the casing could fix that? It shut off normally as if it had a dead battery. How much voltage doeas a generic android board need? Current?Does the board take 3.7v but since theres no battery it wont boot? How could I fake a fully charged battery? Or could I possibly flash a custom rom? Do you guys need more info? I could provide more pics Note that the battery is a 3.7v 3500mah li-ion battery with only a positive and negative hookups. Also i took some tape and covering off the battery to see if it possibly had its own controller board. It did have a small  pcb board but it seems that its only "a transfer" board, it takes the power from this cloth like cable and passes it into the wire thru the pcb. Should I try to hookup 5v straight to the battery to test it out? Battery has 0v so it might be useless.

The proper circuit for ultrasonic transmitters?

Hello I am new with ultrasonic sensor related works. This time i am going to use ultrasonic transducers which are not ultrasonic sensors(with board module) that people use. I have there transducers named v33an16t and arduino uno module. So i need a proper circuit to connect these transmitters to the arduino module.I can find many circuits from google but i need the proper one to save my time.Because my purpose is to design machine learning method using the transmitters. And the reason why i did not buy ultrasonic module is that i would increase the number of transmitters like an array. Also shape of the array may be changed depending on my research.So to save my time by avoiding building various of circuits i need your help to build the proper circuit.I appreciate any comment.

What did Google Maps cameras discover over a lake in Switzerland?

Google Maps have been taking "street view" images for a number of years now, and they've captured some interesting things... In this case, there's a ghostly figure that appears over a lake in Switzerland. If you want to see it with your own eyes, go to Google Maps.   Copy and paste these coordinates for the location: 47.110579, 9.227568   Zoom in until you are in street view.   Then look to the sky (North-West over the lake). Was this just a strange camera anomaly? or something more divine?

Cfmoto 650 - possible options to derestrict the Australian model

When it comes to motorcycles with restrictions then Australia seems to be pretty much alone in the world.Despite an abundance of bike to choose from that would fit weight/power limitations it seems to be common to go overboard here.As a result basically all popular motorbikes up the 650ccm hit the AU market in a restricted form if they don't match the limitations by default.For someone in the US just reading this might sounds like a useless concept to get people to learn how to ride a motorcycle.As a fully licensed rider and being on a budget a bike for just over half the price of a Japanase model is still tempting.And for general touring use the MT is actually quite a comfortable bike.Big downside is the impossiblity to get certain bikes in an unrestricted form.For the Cfmoto's of the older type, running the Ducati ECU it is as simple as adding a suitable fuel/ignition tuner module and removing the physical restrictions.The newer models from 2017 onwards use a more reliable Bosch ECU though.With them it is appearently possible to use BWM tuning module but with the requirement to do a full remap on a Dyno.The 2018 MT is my bike, so I will focus on this, but the gerneral things are identical on all the Cfmoto 650 models.A word on the legal things first....Outside AU none of this concerns you as your Cfmoto will come unrestricted anyways.Within AU however we are subject to several laws that make the legal modification of a so called LAMS motorcycle virtually impossible.You can even put a different exhaust or airfilter on them without risking to loose your license and get some hefty fines.As a fully licensed rider however the law often turns a blind eye on these things as they don't really matter as long as they won't affect the safety of the bike, rider or other road users.With the plated riders out for now, let's focus on the options for a fully licensed rider, shall we?There is no need for a RWC or anything if you already owned the bike in the LAMS version.But if you try, for example, to go to Vicroads and have the registration details changed to reflect that the bike is now running with it's full factory default power, or a bit more you are lost.Two reasons for this.Firstly Cfmoto did not bother to import and register for road use any unrestricted version of the 650's.Secondly the VIN number and engine number are fixed in a database for LAMS only bikes.You would need a full engeneering certificate to register the bike in any modified version that affects the power output or reduces the weight of the bike.Sets you back about 10.000 dollars and still won't garantee that Vicroads actually transform it into a legal, unrestricted bike.The police has little to no interest in what a fully licensed rider does to a bike - within the usual limits of course.And since you would not sell the bike without fully reverting it back to the LAMS state the risk of prosecution can be fully minimised:If your insurer agrees to provide full comprehensive cover once the bike is (properly) reverted to what the international models are it is down to serious accidents that might still cause trouble.For example when you cause severe injuries to someone else the bike would be checked for modifications that could have had an influence on the accident.My insurer explained it like this:If the bike is checked roadworthyness after an accident it would fail because it is no longer LAMS compliant.That would automatically default the rider to be responsible for the accident even if not at fault at all.With that it is mandatory to have all the details about the modifications listed and validated in the insurance policy!Adding a tuning module for example would mean providing a fully Dyno chart with a safety confirmation from a licensed vehicle tester.For example the confirmation would state that a power Commander with Auto Tune module was installed together with a slip on exhaust system.Bike specifications allow for the save use with said modifications based on the results of the Dyno runs.With that the rider is put back into legal territory as the insurer stands for the roadworthyness of the modifications.It certainly helps to just stick with the default options and to provide the Cfmoto cert copy from the same international version of the bike.A plated rider should never attempt any of this as it still means there is no way to get away - legally and financially!Possible tuning options for the LAMS versions:Adding one the usualy tuning modules is not only pain but also costly if done properly.Being a LAMS bike you will have a hard finding a reputable shop to install a tuning module for you.Doing it yourself can be tricky, especially if you consider that the default wire colors are often different on the bike.Takes a few hours to check the wiring diagram, follow and measure connections and then to finally risk starting the bike....It works though if you know what you doing.Biggest downside is that you won't find any ready to go maps that you can use.And trust me trying to modify fuel or ignition maps yourself is not for the faint of heart and only an option if you a) know what you are doing and b) have the tools for it.There is a good chance the bike actually runs worse than without the module.Now the obvious solution would be to go for some Dyno runs and to have it all setup properly.Again, with a LAMS bike you will have a hard time finding a licensed and reputable shop to take your bike in.If you find one that does it anyway than it really is best to go for the full package and to suck the costs up.Let them supply the required modules, sensors and all, deal with the airbox and throttle limiter.Then have the usual 3-4 Dyno runs to get the mapping done properly.This approached worked perfectly fine for the older bikes using the Ducati ECU.The new models with the Bosch ECU might still struggle to accept the tuning changes.Reason for this is the checking of literally all sensor informations.Means the tuning module must cater for this and not just fool the O2 and TPS sensor readings.Just removing the throttle limiter and airbox restrictions will cause the bike to run too hot very quickly and also puts your ECU into a lean default mode once you see ECU errors flashing on the dash.Real tuning options that won't have a chance to harm the engine:With all models available internationally and without any restrictions it is relatively easy to find a wrecker in the US, EU or even Asia to supply parts from crashed bikes or those confiscated for destruction by dismantling them.If you are a fully licensed rider and after a bargain or love your first bike so much that you want to keep it once the plates are gone:Organise the ECU, airbox and throttle body from any part of the world except Australia.Sometimes you even find them on Ebay so pay attention to the sellers home country (some AU sellers go international and would then just get the same what is already in your bike ;) )!!Why not just the ECU you ask?Our airbox has added restrictors, just removing is not the best option as they are also responsible for causing required turbulences in the airflow.A straight through or even pot filter option would again require ECU tuning.As said, talking stock here...The throttle body might not be required to get the full power the bike is intended for but you never know for sure.If in doubt pay a few bucks more and have the injectors and sensors included as well ;)But why would I want to pay for a throttle body if it is not 100% certain I would require it?It would'n t have the screw hole for the throttle limiter ;)This tiny detail can be of importance if you go the full lenght, more on that later.With those three components (or two if you want to go without the throttle body) you have a stock international version of the 650.Makes it relatively easy to convince your insurer that the bike is safe to use in this configuration.Adding just a slip on is no problem either as the normal ECU runs quite rich in the higher RPM's anyway and the new exhaust would not make too much mess here.But adding a less restrictive airfilter will need Dyno tuning.Going the full length, especially interesting if you buy a second hand Cfmoto.It will take you a lot of Emails and some overseas phone calls but it is possible to find a wrecker that can sell you the registration plates for the frame of the bike - legally if said wrecker is allowed to sell frame number for rebuilds.Adding this plate to your order means your second hand bike can be deregistered, sadly this means unless you pay extra you need to hand in the numberplates as well.No big deal however if the bike comes without numberplates anyway.Once you installed all parts and replaced the frame ID plate you take the bike for normal RWC check and get your green slip.With that you go and ask to register your bike with new (or your old) numberplates.The Vin will not show up in their database and a red flag comes up, prompting some questions from the offcial behind the counter.The bike you know have is an imported model you got for cheap when you saw it for sale in some carpark with a blown engine.As the actual engines are identical you replaced the blown engine with one from an AU bike that crashed and was written off.In return you now pay a slightly higher than usual transfer fee but get the bike registered as he international model without LAMS restrictions.Even the engine showing up as a LAMS engine is of no concers here as there is no legal reason to not allow the use of a lower powered engine in a motorcycle.You insurance polcy will also go up a few bucks but that is not really worth crying about now anymore.Once you go out with your numberplates you can enjoy a legally derestricted (imported) Cfmoto.Ok, I got it an I say I am a fully licences rider that does not care too much and wants to go as cheap as possible...A brand new ECU from China sets you back about $400AU.Downside is that you are never 100% certain the mapping will fit what is installed on your bike.There might be differences for the US or EU market, not so much though for Asia - so ask for what market region the ECU is intendet and prefer the Asia market here.The airbox limiters should be safe to remove but you might have to make simple plates up to install so the air turbulences are within specs - you will notice if the bike runs really crappy in the high revs and struggles to provide power to the wheel...Unless Cfmoto actually include more limitations in or around the throttle body going with stock should be fine - flashing ECU error will tell you if not.Postage from China can be a pain, not so much for time it takes but for the money charged to use proper and trusted courier services.Up to $100 just for postage is not uncommon but also means the parts are your within a week or 10 days most.Some provide cheap flat rates but both have the risk of being asked to pay import duties if held by AU costoms.Going second hand from some wrecker outside AU can be slightly cheaper for the ECU but again postage can a pain on the pocket.The obvious downside is that the bike with such a simple and direct mod would be still a LAMS bike and if checked make it illegal to use with all the corresponding consequences for the rider - even if fully licensed, please check the above insurance part again if you must.If done properly and maybe even with a slip on: what gains are we talking about in actual figures on the wheel?To be honest not really that much at all, the bike is just too heavy.But the response will improve noticable!The bike pulls out of corners with ease now and no longer requires you shift through the gears with a screaming engine.Imagine you have a small, 4-cylinder car and went on a long holiday trip with your heavy camping trailer always attached.Holidays are over, you unhook the camper and go for a quick run to the shops for supplies.It is that wow feeling that you get when you take off with the weight gone...The gears run higher with a more evenly distributed power instead of just a narrow window of RPM's with enough power to pull away.The KW and RPM values are available on the Cfmoto homepages.What about top speed?I managed to get to a full 110km/h !! ;)For anything above that ask your local Dyno please or pay for a day on the track.What if the police gets me and makes trouble because of the modifications?A well trained officer in a bad mood will always be your nightmare.So I won't go into the troubles if you still need plates or just got your full license a few days ago...You are allowed to ride any road legal motorcycle, no matter the power ratings.However, a really pesky cop wanting to go by the full book on you will use the computer to check your bike and registration details.And if he knows the most obvious non-legal mods to LAMS bikes, like the shiny exhaust you will need a lift home.Chances are though that a clean driving record and having your full license for a few years indicates that you actually know how to handle your bike properly.That is the point where your honesty and details with the insurance company matter.Preferably with you having a copy of your policy with you when riding the bike.With that you can always argue the modifications are documented and approved by your insurer and corresponding vehicle tester.Makes it then only a minor offence for not being LAMS conform.The paperwork to fight you on what your insurer singed off for is just not worth it with a possible drunk driver getting past while you argue....Legally they can still book you or even take the bike but do they ever bother to take those Harleys or street racers with screaming exhausts you hear from miles away before you even see the bike? ;)As said, it comes down to a LAMS offense that is fully covered by your insurer and with that not really worth making a big fuzz about.If you got pulled over for speeding or other offenses the story will be different though as it then could be argued you made these modifications with the INTENT of illegal activities - like speeding or pulling stunts that are not allowed on public roads.Here you insurer can refuse the cover the same way they would for the same offences on a fully legally unrestricted bike.Is it worth taking the risk?No, it is not!If you are after a bike with good handling and power you would not ride a Cfmoto...As a true LAMS bike the resale value is actually quite good if the bike is kept in good condition.Modified you will have a hard time selling it as no learner would take the risk - a working brain assumed here.For a keeper once fully licensed or someone on a budget it can be quite tempting.After all, it leaves a nagging feeling if have a full license and sit on a restricted bike....You always have to explain what you ride and why anyway every time you pull over where chatty bikers are around.Selling the bike in good condition and maybe together with the extras you got over the years might be enough to justify the extra for a second hand bike from Asia, Italy or Austria and give you more leasure and pleasure in the long run.Doing it properly and in the most legal way costs quite a few bucks.If you add this to the current asking price of around 7500 ride away will add at least another $1500.Depending on the exhaust system even more.If you require proper identification and tracing of things like VIN plates it can be clse to $2000.At this point you already see really only makes sense it is a cheap second hand bike, whicj makes the entire approach a bit questionable anyway.With now close to $10.000 for a new bike the difference to a well known brand with maybe a better reputation is not that big anymore.The bike would already be unrestricted and making road legal modification wouldn't interest anyone.Not to mention of course the warranty issues as Cfmoto won't honor any of it if you modify new LAMS bike!Now add the possible costs for repairs or parts that would otherwise be free and free of labour costs and the bargain becomes very expensive before the warranty period is over.There will be the point where you ask yourself why did you bother in the first place....Warranty....Once modded the factory warranty is void so to say.Problem here is that the law is intentionally unclear on the reasons and options applicable here.As the bike would (without exhaust mod) be just like any international model the law states the warranty must be granted.However, Cfmoto has the right to refuse it anyway based on the exclusions required by law to prevent non-LAMS conform bikes from getting back on the road.A blown engine with a proper service history would be no big deal without this.The right to refuse a free warranty replacement for covered parts if the bike was not serviced by a licensed dealer is something car manufacturers already failed with.Cfmoto however will argue that their terms and conditions always superseed any Australian laws or regulations unless it was legally shown that one or more sections are actually invalid in Australia.This includes any evident or suspected tampering with the LAMS restrictions.If in doubt an ECU reading would indicate the impossible throttle positions used and the different ECU.Means even once the warranty is over you can't really take your bike to your dealer for a service or just a check without risking troubles.Some say this is still not enough to deter restricted drivers, I say that any fully licensed rider should have the right to enjoy his bike without LAMS restrictions.But if in doubt Cfmoto is always right, no matter how they argue.Last words from the wise camel....If you are fully licensed it is entirely your choice what you do with your bike and how you deal with - or interprete possible legal issues.Anyone required to display plates should just not think about modding the bike, it is not worth the risk.Although not really a big deal for an experienced rider, the added power and better response can cause a bad judgement.You might have been happy to open her up fully around your favourite hiarpin bend but now it could mean you loose traction even if don't try to break your LAMS approved speed record.Especially when things get a bit slippery and unexpected it can be difficult to prevent the heavy beast from going down.Never underestimate what you can't see and react to in time!Never overestimate your skills or the bikes real capabilities in terms of handling and grip!Once you are fully used to the different response you are fine, until then it is better to play it safe instead of ending up to be very, very sorry....

Motorcycle communication without expensive BT headsets!

When it comes to communicating with the person on your back seat then often there is no need for a fancy BT headset.Unless of course you are constaly driving on freeways at high speed and love to talk ;)The most annoying thing though is when you want to go for a long ride with a lot of your mates.Some might already have some BT headset, most might not have anything to communicate.Even with just 8 or 10 riders in your group, loosing one is easy.The most advanced headsets now offer functions for automatic pairing when the connection was lost - they come at a price though.Around here there is two problems to face when going for long rides.a) communication range for the riders in the group.b) cellphone coverage is usually non existing when you actually need it.So why not go with something totally different and much cheaper than BT headsets?At highway speeds the range of BT headsets suffers not just from the required safety distance between riders but also from the spped itself.Cheap headsets just crap out all the time, expensive one tend to loose the connections quite often.Wouldn't it be great to have more than the average 800 meters of good sound quality without dropouts?And if you ever tried to have a decent converstation with another at high speeds you already know that even the best BT headsets struggle with the wind noise unless you have a really optimised helmet (and paid a lot for it).The alternative, if we trust all the hype and advertsiements would be to go for the latest generation of headsets out there....Baofeng UV-5 series....This type of UHF/VHF handheld radio has ben around for years.It is not only quite cheap but also able to put a full 4W out.So called battery eliminators to power them directly from a 12V socket (in your car) are cheap as well, but a good battery should last for a few hours.The benefit of these cheap radios however is not that they are so cheap.It is that you can actually program whatever frequency you like for your needs.Of course you should stick to the frequencies and channels that are free and legal to use in your area.The since is about what a pack of smokes is, so no problem to mount it descreetly on your dash or handlebars either.Being a radio there is no need for pairing or making sure you stick to the correct order when doing things.If you want to be "alone" on a channel you can even use celectcall and other option to make sure only those radios with the right callsigns wil open your squelch.Quite nice if you suddenly get into an area where your channel is used by ther people.Ok, a handheld radio might work, but what about the antenna?The UV5 series usually ships with two antennas.A short stubby that is good for about 1-2km - line of sight.And a small external antenna with a magnetic base.On a bigger bike it is often no problem to add a 15x15cm plate behind the seat that the antenna can pop on to.Should only be required if your require a bigger distance though.And why would a UHF radio be any better with the background or wind noise?Biggest problem with these expensive BT headsets is that you need to get really creative if you want to change the speakers or microphone.And options are quite limited here again - either a flexible microphone or a glue on one.Neither is really good once the wind gets too much.For the UV5 series you get so called throat microphones for under 10 bucks.Often advertised as tacticle headsets but for the price nowhere near the quality of a military grade combination.They plug straight into the handheld and come with an external push button that can be used to start a manual transmission.But of course you can automate this on the UV5 as well by selecting the voice activation mode in the menu.Set the level so high that you need a slightly rised voice to start the transmission.(That way not everyone needs to hear you swearing about other drivers if you keep it quite ;) )All up a solution like this will cost you well under $100, with all required extras.For a bit more you can also get UHF radios for helmet use.Basically the same like the handheld option, but smaller, a bit more convient to use and set up but also very limited in range and battery life.

Steam generator for a home-made steam room

I love steam rooms. i want to build one out behind our house in the country in thailand. but it has to be low-tech. i'm thinking i'll make a square wall out of cinderblocks, about 4 feet high. then my shower will stick up from that .we don't have running water. we get water pumped from the well into big jars and use a bowl to splash water on ourselves to wash. but i put a submersible pump in the bottom of the jar, rigged up some PVC pipe and i have a shower of sorts. so if i build a 4 foot high square wall, with a doorway, i can pull a thick piece of foam over the top to cover the top, hang a rubber curtain across the doorway opening, and have an enclosed, outdoor room that i can steam up and sweat the gunk out, then stand up, flip off the insulating cover and shower right there. the steam room will go right behind me and the jars in the shower picture- where you can see a little bit of grass growing. but how do i make a steam generator? commercial ones cost way more dollars (baht) than i need to spend. i can use propane from a tank for fire, or wood, or charcoal. the well water is very hard water with a lot of dissolved minerals in it so my steam generator can't be something that will get clogged up with mineral deposits. anybody got any ideas? the steam generator needs to be cheap, home-build-able with local materials, and safe... don't want anything that can blowup, catch fire, or asphyxiate the users.

Quantum Levitation

Wow, just in time for The Mad Science Fair- an awesome magnetic levitation set-up. The Superconductivity Group at Tel Aviv University have been working on thin-films of superconductive materials and have found some...cool effects.  The thin films will apparently have a few defects, resulting in very specific areas where the magnetic field permeates.  This rigidly constrains the composite, allowing even "up-side down" levitation! (locked in space, beneath a magnet.)  Would be so awesome to play around with but apparently the deposition of the superconductive film is a real challenge, not to mention the sapphire substrate. A forum post at HI Capacity had these links, probably after a member saw Gizmodo's article "What the Hell Magnets? Why Are You So Amazing?"

5 pin digital LED light strip (intertek): Can you cut this? Answered

Bought intertek model 17084 from costco. Has 3 12' sections that can plug into each other to 36', 24V PS with remote, has programmed features such as racetrack, color changing, etc.   I want to put on my deck railing at the following lengths 13', 10', 8'  with gaps between where stairs are. I bought ledenet 10mm 5 pin connectors you can see in the picture and I bought 5 wire HVAC copper wire to solder in the longer gaps. Plan was: = Make longer connectors by cutting the ledenet connector in two and soldering in the 5 wire HVAC to length. PS => 12' led strip 1 + 1' of led strip 2  => connector => 10' of LED strip 2 => connector => 8 ' of LED strip 3 with terminator cap. If you can see in the picture, I did not cut right at the cut line, rather down the middle of the solder joint. Just testing on the 13' section using no connectors (but using the factory male/femail connector) only the 12' section works. The one foot section glows a slight bit on the color LEDS, but the white only LEDS work fine.  So I thought maybe it needed the rest of LED Strip  two to work, so I connected the 1' section back to the 11' section using the LEDENET connectors. Now, the whole second section does not work either (except white). The only thing that is different from factory is it is connected by the ledenet connector.  Pins are: 24V DIN CHECK W GND Anyone have any clue why this wouldn't work for the color and programmed LEDS? I would think each 1' section is independent on each other and would just receive the signal and send it to the next section.  Could it be programmed to only work in 12' sections? Did I kill a LED somewhere in that 1' section?  Very baffling. Thanks!!

Should I be worried about beryllium oxide poisoning? Answered

From what I know, the magnetron in a microwave has some beryllium oxide on part of it, which is highly poisonous. I'm pretty sure the magnetron I dealt with had some (it was a pinkish-purple coating on the tube).  I didn't do anything to it, but I think some of it may have gotten accidentally scraped off with the screwdriver I was using to open up the magnetron.  BeO is a carcinogen and can cause CBD.  If some of it did indeed get scraped off (and I have no idea where it went, maybe into the air?), am I in danger of beryllium poisoning?

How to connect 5V USB heated pads in series

Hi all,This is my first post here. I ride a motorbike and would like to do a DIY heated trousers and jacket. I found these pads 30cmx30cm that run off 5V usb sockets. I want to put 4 in my trousers and run them in parallel so I only have one connector to plug in whenever I ride. Is this even possible with USB ports or would I need another connector?Heated pads: https://www.aliexpress.com/item/32963771423.html?spm=a2g0s.9042311.0.0.78504c4dTlpjMrThanks,

Are there any natural ways to make voice louder and clearer? Answered

I don't know if there's any way to increase the volume and clarity of my voice, is there?  My voice is too soft, it may sound cute! but, I'm having problems these days because of my soft voice :( When I'm with a bunch of friends or family members I feel like I'm invisible! I have to speak 2-3 times louder than my usual volume!, which ain't easy at all, so I remain quite most of the time. besides, In presentations, seminars I'm getting low grades. The teachers keep saying 'try to speak louder', but how do I do that??? I have good grades, but I'm afraid I'll lose it :( Please, I need help!
