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!

  • Downunder35m commented on Lbcaswell's forum topic Cool gel mats for pets2 hours ago

    Cool gel is overrate for the purpose of actual cooling if you ask me.A warm cat and a pack fresh from the freezer won't mix unless the cat is desperate.And once the temp is just right for the cat to consider a cool down there is little cooling capacity left.Have you though about active cooling?I know you should have enough swamp and water around but no clue if you are close enough to utilise it.But I think if you could add some metal and tubing under your mats then water cooling might be perfect for the right temperature.

    Well, it is nice to know you can see now but that should not stop you from trying anyway.If you eliminate the need for mains power to get the water up the tank you are half way there.Main focus should be on a suitable turbine/generator combo.Off-grid turbines are usually only designed with reliability in mind assuming water is available with no limits, like from a running creek or small lake.But there are other options worth trying, like a turbo from a small car or even a water pump from a slightly bigger car or small truck.Take what you can get for free or dirt cheap and experiment, focus on great torque at the shaft with the water use as little as possible.And: You don't need to produce a lot of amps, you do need to produce a lot of kWh to charge the battery ;)Meaning it is often bett...see more »Well, it is nice to know you can see now but that should not stop you from trying anyway.If you eliminate the need for mains power to get the water up the tank you are half way there.Main focus should be on a suitable turbine/generator combo.Off-grid turbines are usually only designed with reliability in mind assuming water is available with no limits, like from a running creek or small lake.But there are other options worth trying, like a turbo from a small car or even a water pump from a slightly bigger car or small truck.Take what you can get for free or dirt cheap and experiment, focus on great torque at the shaft with the water use as little as possible.And: You don't need to produce a lot of amps, you do need to produce a lot of kWh to charge the battery ;)Meaning it is often better to use a generator that has a higher output in Volts than what you actually need.Take this example to get you thinking:A generator that requires at least 1000rpm to produce 500W at 24V will only give a fraction of that power when running slower.But a generator able to deliver 48V and 500W at the same rpm will still give you enough volts to keep charging the battery when running slower.With that in mind you can adjust the water flow within certain limits to optimise water use.Same story for the torque required to run the generator.Ideally you want the turbine system to only have little reserves left when the generator is under full capacity, everything more will "waste" water.When you found your ideal match for generator and turbine do some math to figure out what tank size you need for a full charge of the battery in question.Down here folks usually only bother with water turbines if a creek with sufficient water flow is available.And still in most cases only as a backup for cloudy days or the winter time with not enough sunlight for solar power.Small wind turbines are now getting more attention as the modern types offer grid syncronisation or can directly charge big battery systems together with the solar panels.Currently a friend of mine is trying to improve the remote home he bought a few years back.No mains power, bottled gas and apart from that only batteries and solar panels.The later was already upgraded to 12kW max capacity on a sunny day.Now we work on using the wood fired heater as a steam generator for a small turbine.The idea is to make a double walled flu and use the exhaust heat to generate steam.Not really easy but thankfully my friend is a licensed boiler maker, so things might actually work out one way or the other.If in doubt it will still help the hot water system to save on gas.

    Take a point high up the creek.Add a pipe that runs from there into your tank, also add a shutoff or overflow.This is how we fill tanks from a creek here in The Land Downunder. ;)Other option if distance is too far would be to use a ram pump to get the water into the tank without any electricity - look it up ;)

    Well, if you need electircal energy to get the water back in the tank then you are wasting a lot more than you might think.If in doubt use at least decent sized solar panels ;)In the right area a wind powered pump on top of your tank will help too.Have ever thought of including at least the neighbours along the line for water?At my sisters place they had a suitable creek three properties up and after explaining what they wanted to do everyone jumped on it and they all ram pumps and tanks.Was just for water use during the summer though and not for electricity but it does help to keep initial and maintenance costs quite low.I did some guesstimations based on jet turbines available here to gerenate home electricity.To reach a target of 500W on a connected generator the smallest possible tu...see more »Well, if you need electircal energy to get the water back in the tank then you are wasting a lot more than you might think.If in doubt use at least decent sized solar panels ;)In the right area a wind powered pump on top of your tank will help too.Have ever thought of including at least the neighbours along the line for water?At my sisters place they had a suitable creek three properties up and after explaining what they wanted to do everyone jumped on it and they all ram pumps and tanks.Was just for water use during the summer though and not for electricity but it does help to keep initial and maintenance costs quite low.I did some guesstimations based on jet turbines available here to gerenate home electricity.To reach a target of 500W on a connected generator the smallest possible turbine requires a waterflow of at least 140L per minute with a minimum height differential from turbine to water inlet of 15m.Mind you this is a 3 jet model with 5 "scoops" driven.Smaller, single jet generators will use less water but still require decent pressure to work - and they will struggle to get 500W.With that in mind even a very efficient pump will require more kWh to pump the water back into the tank than what the generator will deliver.And with the required flowrate it only takes simple math to calculate the need for almost 10000 liters of water to run the generator for one hour....I hope you have more efficient turbines available where you are.

  • Downunder35m commented on garrettlynch's forum topic Joining carpet pieces3 days ago

    One option would be to use cotton strips and contact adhesive to join the pieces.For bigger projects it pays off to buy the adhesive in cans and to use a very stiff paint brush.Best to place on sheet of carpet on the perpared joining strip first and to hammer it in place using a few taps with a rubber mallet - the pressure makes the strenght with these adhesives.The next pice you join "flipped up" so you can really press it against the othe carpet piece before getting too much contact with the adhesive.

    Yes of course it is strong enough and no way it will hold ;)All depends on the type of type you use.For example the dirt cheap double sided "carpet tape" usually sticks really good to itself and all things it should not stick to but fails after a few weeks on carpet with a foam or sisal backing.The good tape uses a quite thick layer of adhesive, almost like the stuff you find on fabric band aids.If you use a hammer or similar to get good pressure it will last really long.Main problem for joining bigger pieces of carpet is movement and stretching, so it really pays off to stretch the crpet in two directions before the final fixing.For joints within a big room I usually use one strip right on the joint and then several seperate strips on top at a 90° angle that are about hal...see more »Yes of course it is strong enough and no way it will hold ;)All depends on the type of type you use.For example the dirt cheap double sided "carpet tape" usually sticks really good to itself and all things it should not stick to but fails after a few weeks on carpet with a foam or sisal backing.The good tape uses a quite thick layer of adhesive, almost like the stuff you find on fabric band aids.If you use a hammer or similar to get good pressure it will last really long.Main problem for joining bigger pieces of carpet is movement and stretching, so it really pays off to stretch the crpet in two directions before the final fixing.For joints within a big room I usually use one strip right on the joint and then several seperate strips on top at a 90° angle that are about half a meter long.These strips will give you the added strength so the seam won't come undone premature.

  • I think it should work, given the shady variations they provide.But depending on the price I still think a new LED lamp might come cheaper, after all you still don't really know if the power supply failed due to being cheap, overused or because one or more LED's are blown.With a lab power supply you can limit the current and increase the voltage until the LED's start to light up - simple test to see if all are still working.

    1+ Without a primer you have no chance on these plastics.Make sure to get paint and primer as a match - certain metal paints require a different primer, if in doubt ask!Last but not least you will have problems coiling it up once the paint is dry as it will crack.I suggest to make the tubing flexible with lots of boiling hot water, then to coil it up tight and cool it down again.You now should be able to strecht the coil enough to paint it and it should go back to tight wrap after if you don't stretch too much.

    Without knowing the firmware configuration it could be any pin really....If the wire is supposed to be an endstop then it would be on Z connector under the PWM connector.The connection for an endstop (with pull down resistor) would be the same as for a ramps board on 3D printers or CNC machines.As I fail to see how auto levelling would work with a single wire I can only assume the machine will drive to the corners and move the table until the wire connects.For that it still leaves the question of the right pin to use.Also wether or not not a resistor is required for the logic.

    No offense, but if you look close enough you will see the single black wire is actually missing from the top motor connection - it only has 3 wires going to the motor instead of 4 ;)So I doubt that your single wire is for a probe and that connecting it to the missing wire of the motor might do the trick here.

    Did you consider using a proper driver circuit for the gate instead of just messing with the voltages?Or just a stable but strong enough 5V for the gate, like using a voltage regulator or zener diode? Driving a mosfet correctly for the application in question will keep it happy and cool ;)

    A belt and pulley system like used for most CNC or 3D printing projects might be far easier to build.And you can change the torque going to the mechanics as easy as changing to different sized pulleys.Don't know your size limits but have you considered going scrap?At the wreckers you can get motors for car seats dirt cheap if you don't mind taking them out yourself.Running on 12V and with massive torque through their lead screw you won't need any complicated mechanis - just use them like a pneumatic piston ;)Some even come with built in limit switches.Bit of a pain to take apart and place in a new spot but these switches can be misused to set the open and close position for the window.This way you only need to connect power to the right wires to make them open and close....

  • There is no real puzzle....Either a special capacitor is used to store the energy or a weirdly designed battery.In any case from there you will have a operating voltage, the power cord usually just interrupts things with a switch in the plug.Remove the battery, disconnect the "switch" and connect a suitable DC power adapter in place for the battery.

  • At least some smart thinking inside a request for once :)Done that stuff a few times and in many cases the voltage used is not what your battery will supply, sometimes with audio equippment you also need a negative voltage additionally to the "normal" supply voltage.Assuming you only need one or two positive voltages the best option is to use a voltage regulator with good filters (check datasheet).A mixer should not need much power so you can avoid noisy step up or step down converters.

  • You problem was already solved many times ;)Batteries and wind generators are not a new thing and adding a computer instead of a fridge or lightbulb does not make any newer...You need to know how much power your setup requires, from there how much run time you need, this gives you the minimum capacity for the batteries.Of course you need to add some extre for times of less wind, heavy gaming or simply longer use.Once you know how much energy your wind generator can produce and how much your batteries can store you might want to get computer parts designed for low power use (or being efficient on batteries) - like a laptop....

    Sounds like the blocking mechanism is jammed.Will require you to take the panel off and the winder out.There is a little plastic bar that moves with the weight of a stell ball - like a rocking horse.Due to dirst and lack of lube they can become stuck.Sometimes you are lucky and a bit of oil and wiggling will do the trick, sometimes things are broken.If in doubt replace the entire unit with a cheap one from the wreckers.

    Shelf life means they will still have a usable charge by 2024 - or you could hope they have.Problem is that they are not really designed for that kind of application as the usage is only slightly over the self discharge ratio.Keep in mind your cmos battery only needs to provide backup power when the computer is off.And since you will only loose the settings but not the actual bios I still see no benefit at all.Considering the costs and work involved I would not take the chance and just replace the CR with a quality one and forget about it ;)

    I did not activate a moving build platform inmy code, nor did I ever test it.So can't really give much help for that.If you mean a fixed table and a homing problem then it will be either in your Gcode or the setup for the printer software.A fixed offset means it stays active all the time, so the axis moves up or down first, then to the start position for the print.An offset in the Gcode will be handled differently depending on the placement and where/how the homing is performed.

    A standard and old school video transmitter will work.Gives you the same AV output.Problem is that this only works for standard resolutions, anything HD and it really comes cheaper to buy the lot.Some cam apps allow the input of a normal video signal, but of course you will need a dongle of some kind or a graphics card with video input.If it is standard resolution you can always buy a cheap WiFi cam and connect your cam instead of the build in one.With a bit of work you can even convert a pan and tilt camaery system to hold your cam instead, but not sure if the motors will handle the extra weight properly.
