The save button in deactivated in Acura 15.04.6

I am trying to export a G-Code from Acura I noticed when I loaded the file, starts processing and at some point it stops. I can see the support material did not finish processing and the top portion is not complete.Then I make changes to the settings I increased the height of the layer and reduced the density.In other words is a lighter density overall. If i decrease this a lot, Then the software manages to finish the set up proces and the save button comback active to export Gcode.Seems like the large data of the higer density settings runs out of Disk space to create the cash.Does anyone know how can I fix this problem?I remember when I work in Adobe after effects editing videos, the software ask me to reserve a dedicated folder with an specific disk space just for cash, when this folder is full, the software ask you to empty the temporary cash files to make more disk space for more projects.Does anyone know how i fix the space disk or what ever i need to do to allow the software to finish procesing with higher density?Please helpYou can email me to gamelicruz@gmail.comThanks

Need a table top that can push stuff upp in the air

Okay so i need some help with a prop for a photographing stuff in mid air.I need a device (flat surface) that I can place objects on and it will shoot them up in the air.Imagine a bowl of popcorn or a pair of glasses with water in them flying up in the air etc. I will then have sensors that will trigger the camera at the right time. (these devices and system I already have)My dream would be to be able to control this "jump table" device thru a simple solenoid valve. (12v) So my rough plan is to have to sheets of wood 40cmx50cm about 1cm thick.Next is to have a pneumatic cylinder in between these two that will push the top plate up and down.I probably need some sort of guides in the corners of the plates so it moves correctly.The pneumatic cylinder will be controlled by a solenoid valve, the solenoid valve i hope to turn on/off with a 12v power supply. The easiest solution for air source would be a co2 cartridge.But if that's to much pressure for the components maybe a cheaper air compressor in a smaller size is usable ?So what im looking for in general advice in terms of pressure and pneumatic cylinders, which i do not have any experience with.This video pretty much has the basic components i need i guess ?Any general advice what to look out for when choosing components and air source ?Thank you!

Site updates, upcoming changes and developments

As it seems the support team is still working hard to improve this ection I would like to take the opportunity to provide a base for everyone.Users can post bugs they find, feedback or suggestions for features they would like to see or have here.The support team could be so nice to keep us updated about what is planned and when to expect some problems or hick ups.Maybe even a list of things already in the planning for us.There is already a quite long list of requests that grew over the years, so maybe the support team could start the conversation with some infos? ;)

Here is the link - https://www.instructables.com/id/DIY-Digital-Clock-With-7-Segment-LED-Display/. Can anyone address this problem and suggest what I did wrong there? This never happened before to me.

Tips or products you recommend for clearing or preventing ice in winter?

My partner and I just bought a house and we're doing some repairs and upgrades. One of the major things I want to focus on is making our front entrance less icy. Most of the time we're covered in snow, but whenever it warms up briefly we end up with an icy disaster on the front porch the next morning. :P Currently, the roof melt runs right off onto our front steps and it's a mess! (see picture for the icicle death trap)I have been using a "pet-safe" ice melt (we have two dogs who are in and out all day) but it doesn't do enough for how much I go through. I still break up the ice in the morning when using the ice melt because the ice builds up really quickly.Are there gutters strong enough to handle heavy snowfall? Some sort of heating element I could install? For reference, I'm in northern CO in the mountains and we tend to get feet of snowfall every winter! I've never lived somewhere with this much snow, but I'm hoping some of you do and can offer some suggestions :D

What is the most affordable laser cutter for a beginner?

I really would love to try out laser cutting. ..But have no idea what knowledge it requires. I want to be able to design and cut custom wooden puzzle, laser cut fabric and also to cut felt and foam. I would like to start up a small home business. Keeping in mind that I have no clue what knowledge it requires and also know that I have 4 kids and will have to have this machine in my home. I do own a silhouette cameo but unfortunately it does not cut felt or wood. It’s a fun machine for cardstock and all…but nothing heavy duty. So is it safe to have a laser cutter at home with kids?? I mean will the light or whatever that comes off the machine be harmful for my children? Also how much is the cheapest desktop version? Will it be able to cut large fabric? Can it cut 0.5” or 0.75” hard wood?? Would that be pushing my luck?? Please let me know…so I can start saving up for it. I really really love crafting….but availability of items and affordability is a big issue. Thanks!

HP, Lenovo, ... Laptop Bios update boot loop fix

I had to install Windows on an older HP laptop today.And being the nice guy I also updated the Bios to the latest available.Now these Windows tools for this job are great fun, start it, press a few buttons and all is updated.Well, until you realise the thing ends in a constant bootloop going back to the bios update part created on the recovery/backup partition.Going the official way by asking the support is pretty much useless as my searches only came up with copy and paste answers but no solution.Some people got desperate enough to order a new bios chip, program it and solder it in :(But the fix is sooo easy and obvious that it might take a little kick to realise it ;)I assume you downloaded the right tool and bios update.For HP and Lenovo it all comes in one pack anyway.I also assume the tool stated that all went fine and the backup and update were done correctly.Now the boot loop that you experience is actually on purpose ;)You are required to enter the bios - for my HP it is the ESC key, then F10.Here you load the defaults, then adjust what you need - like the boot order.Once you set the boot order to the internal HDD or the OS boot manager you are good to again.I hope that will help the desperate people that got nowhere by trying the support for their laptop ;)

10 Best Electronics Suppliers

First off, I would like to give notice to Electronics Projects for Dummies for most of this info.I wanted to make a site with many of the best sites to buy Electrical Parts, because it can sometimes be a strenuous activity. I have 10 here, because if you can't find something on one online store, you might be able to find it on the next.Reynolds ElectronicsReynolds Electronics is a good supplier of remote control components, micro controllers, and robot kits and parts. One feature that stands out on Reynolds Web site is the clear and helpful project/circuit tutorials. You can also find links for educational books on topics such as robotics and microcontrollers.Hobby EngineeringHobby Engineering is a sit slanted towards the hobbyist. This site carries some useful items that can be harder to find from other providers who are catered towards the corporate customer. it also has a good supply of micro-controllers, robot kits, parts, ad miscellaneous components and tools.All ElectronicsAll Electronics has an incredible selection of many of the useful items you would use to build your project. They are very inexpensive and it is easy to find your way around the site. This site also has a "consumer comments" section where the consumers get to talk about the quality of the product and more. (Thank you westfw)BG MicroBG Micro is a cool site for rare and pretty neat gadgets as well as a nice selection of alot of the items one will need for a weekend project. There is also a very nice search engine at the top which lets you search for an item you can't find on the left. (Thank you Las Vegas)Jameco ElectronicsJameco has a very nice site catalog. It's not very big that you sspect a forest was sacrificed in its making. I has great color photos with relatively easy to find components. This is one supplier wih a low price fuarantee which means that if you can show a part offered for less, the lesser price is honored. jameco also provides lower priced generic products as well as name brands.DigiKeyDigi-Key is a large distrbutor of components from various manufacturers, offering a very large catalog with lots and lots of choices. However, the site uses small print that might be hard to ead. The catalog includes line drawings but o part photos, but it does do an excellant job of labeling the parts. Overall, Digi-Key has a huge selection of products, but they might need a little looking to find them.loading...Mouser ElectronicsMouser ElectronicsAnother large distributor of components from various manufacturers is Mouser. I like how Mouser's site allows you to compile separate orders for different projects. You can come backa s many times as you like to complete your order and make your purchase. We also like how Mouser label parts because the labels are easy to read and provide alot of information about the specific part.Like Digi-Key, Mouser provides a very large catalog.RadioshackRadioshackEveryone knows Radioshack!. This electronics convenience store is pretty much like any food convenience store: CONVENIENT BUT EXPENSIVE. If you are stuck at 4:30 on a Sunday afteroon needing a small part to keep working on your project, this store is right for you. Be aware that not all radioshack are equal.Fry's ElectronicsFry's ElectronicsFry's has stores in nine states, and if you are lucky enough to live near one you can browse the isles in person. Fry's stocks all kinds of electronics and parts including an EXCELLANT selection of IC chips.Goldmine ElectronicsGoldmine ElectronicsIf you are in the market for bargains, try Electronic Goldmine.. This online store often offers sepcials that can save you money. Based in Scottsdale, Arizona, Electronics Goldmine offers great help with international orders and also offers wholesale items on auction on eBay.Quick Tip: Try clicking Electronic Goldmine Treasure Ball for the best deals!FuturlecFuturelec offers a very nicely done site with color photos of the parts that makes for easy browsin. Futurelec also offers semicnductor news links and also links to recently added parts to help you keep on the top of the latest and greatest as well as PCB design and manufacturing services.[htpp://maplin.co.uk Maplin]MaplinThe British suppplier Maplin has stores scattered around the U.K. and also offers an online store.Unlike electronic gadgets and appliances that operate on different voltages in European contries, electornic components are pretty standard. Although Maplin will ship overseas, you might want to check out U.S. Suppliers first.SparkfunSparkfun was originally a PCB Manufacturer, and turned in to a company well beyond their expectations! They have a large variety of PCBs, LEDs, and MANY more everyday electronics components. The site is well organized with so much to choose from!

Make use of iCamera 1000 units?

I have 3 "iCamera 1000" camera units laying around. I do not have the rest of the security system they are designed to function with, but there has to be some way to make use of them and have some fun. I have lots of cat 6 cable and RJ45 connectors to custom make a cable if anyone has the expertise to figure out how to make use of these. Before posting here, I searched and searched here and on Google but only found information regarding the "normal" application of these cameras..... I was hoping for something more outside the box which is why I am here. I included a front/back picture. Thanks for any ideas!!

Rex C100 temperature controller - changing settings

I recently ordered a REX C100 for my electric melting furnace project. As it came already with a SSR and temp sensor I only added a sensor capable of reading more than 400° of the supplied one. These controller are dirt cheap and have lots of support in the modding community - although you now can get them new in all variations so no more modding required. Internally they run on 12V DC, so even mobile use is possible (but this time after modding). My problem with this controller started with the not included manual. As it is no China clone but an original from RKC Japan, I downloaded their manual and tried to adjust the max temp settings as well as changing to the thermocouple. To my surprise the menus for that simply did not exist on my model. Reading a few more manuals showed that to get to the "initial or factory setup" you need to change the lock code. Here things get confusing: Once in the lock menu setting most manuals state to enter "0000" to activate the hidden menus. (Mine was alreay on 0000) Others state to set the code to "0100". In any case you have to hold the setup key for a few seconds to store the changes and after that hold the settings and shift key for about 5 seconds to enter these factory menus. After being close to send the unit back I tried different code combinations and finally found that "1000" actually activates the hidden menu on my model! But again there was no joy as several vital settings still did not show up. To finally get all settings another step is required: The first item in the hidden menu is "CODE" and it shows as "0000". After changing this to "0001" the setup key can be used to get to the settings to change the max and min temps. Once all this done the controller actually shows the selected sensor and if Celsius or Fahrenheit is used at the start and from now on simply by clicking through the hidden menu with the setup key you can get to the min and max temp settings again. I hope this info will help someone running into the same brick walls as I did...

The "truth" about climate change - a little story

Global warming, climate change, jelly fish attacks, changed ocean currents...We all know the highlights from the news but what is the real deal behind all of this?It can't be denied that burning fossil fuels with no regrets has an impact on our globe.CO2 and other gasses or elements have been trapped for thausands of years.We release them all into our atmosphere and while doing so keep adding more harmful stuff.So, of course it is easy to say that if we would have nver used our fossile fuels to this extent then our world would be unharmed and a happy place throughout.Even if we would ignore the impossible task of making it where we are right now without having used any fossile fuels: How much would it be different?If we trust the offical climate data that has been collected then it clearly shows a rise in so called climate changing emissions since our industrial revolution started.Be it data from the ice, core drillings or just sample taken from old canyons - the results are all the same.Since the late 1800's there is a steady rise in emissions, CO2 and all the other things we don't really want in our air.And for good reasons all these green advocates try their best to stop us from doing more harm.Since the 80's we started to actually care more, better engines, catalytic converters, cleaning mechanisms for our industiral waste and chimneys.But did it make any change or difference?About 40 years now some countries try hard to do it right, so this must show up somewhere?!Well it does not.You see countries like the US never really cared about climate or the enviroment if there was a cheaper and easier option.Just check how long it took them to even acknowledge that our climate is changing due to our interference...Then there is China and as we have seen with the olympics they literally have to shut down production so you can see for more than a few km...But the same is true for so many other countries.Like everwhere else the industrial revolutions comes sooner or later and as always the cheapest way is done first and for far too long.And with the delay in reactions and consequences it is now certain that the worst is yet to come.Of course there is also another side to the entire story - nature itself.We destroy it where we can to safisfy our need for being cheap.Ever wondered where all this cheap furniture is coming from?Or all the wood used throughout the world?Rainforests are disappearing, flora and fauna is destroyed.In most cases with a lot of fires as it is still the easiest way to clean up when done.Now add the vulcanic eruptions that increased over the past 20 odd years around the world.And if you dare all the bushfires or natural causes.Combined this causes a higher impact than all our burning of fossile fuels - and it adds to the mix.And this brings us back in time.Taking the records of climete conditions all the way back to before the dinosaurs showed us that we had periods of much higher temperatures than what we might see soon.CO2 level at some periods were so high that the earth literally was a green house.So why did we humans amke it anyway onto this earth if chance were so bad?Species adjust, evolve or go extinct, new ones appear...Well, unless you are a croc or so and really don't care about Darvin and evolution ;)Does that mean we are on the way to become a new species?Sadly no, because we are the cause of all our problems.We now use technology and science to adjust nature and the enviroment to our needs.It gets too hot? Well add an airconditioner, will you!?The ground water is too contaminted to drink? Well, why do you think we invented bottled water?!You need room for new homes? Don't mind the flood planes, just drain them and build, there was no flood in over 30 years...See, even if we would go fully green and honur nature around the world from today on.Even if we try to clean up the mess we already created.The effects of what we did over the last 40 or more years are still in progress and far from over.Like a good stew it keep cooking until it is ready to serve.But strenght comes in numbers!Like a virus we keep multiplying even in areas with very limited ressources.After all, we just import what we need..Natural selection is being eliminated so pharma companies can make a living too.From just over 40 years our "natural" life expectency increased now to well into the 80's.You are not fertile? No problem we have means to fertilise your eggs with the sperm from hubby!Already suffering badly from diabetes, asthma or other chronical illness? No problem, have some kids anyway.And just to top it always make sure to avoid natural foods in favour for processed and artificial ingredients.In nature the weak, the sick, the old, the malformed and incapable are a food source.We took this food source away, keet them around, care for them and make sure really everyone has the same chance in life.In life - but not in nature anymore!Social evolution meant that natural selection was no longer a requirement to ensure a strong "tribe" or hunting party.We compensated the drain on ressources and all pharma companies are still very grateful for this.No this is no weird rant on humanity or the idea of some mad person, it is just the naked reality we like to ignore.A horse breeder will not accept a weak and constanlty sick horse for his breeding stock.A broken leg, like for a cow usually just means the animal is put down.Some dog breeders still prefer to cull a few pups just because the color pattern is not nice enough or the ears are too short.Even if you just breed fish you o through all sorts of troubles to ensure you have the best genes available in your tanks.You think this is already going to far with the ideas, I know :(But we have real world examples highlighting the results of the exact opposite: Inbreeding and ignoring the defects in genes and health.The british royal family destroyed the italian and russin monarchies the same was the spanish and protugise, even impacted on the french.In times when there was no clue about genetic defects or deseases that can be dormant in females but very active in males, the british royalty simply kept providing tainted bloodlines to the other royal familes.No offsprings that are male and of good health meant the end of their monarchies.The british survived by allowing the common folk to join the blue blood lines and now it is common in all the monachrchies left in the world.Remove the carries, provide fresh genes to get a better diversity.Really no offence, but just look at Charles and Camilla ;)Jokes aside: the story of the european monarchies shows what happens if things go too wrong.From hunters a gatherers that either kept healthy or died out we eveloved to having a gene pool that is full of nasty surprises.Again no offence meant in any way or to any person!If we compare our world with a big aquarium than it might have eveloved like this:Once there was a bowl full of plants, guppies and lots of other fish and creatures living on each other.Over time the guppies learnt when the feeding times are and made sure they get most of the food.Slowly the other psecies had not enough room and food anymore, only the hunter had a good linving with the huge supply of guppies.Then the guppies managed to reduce the dangers from all predators around and started to really take off.Soon every guppy had only conerns about having a good life and enough food.The waste got more and more, the sick and ill too.The last hunter able to fight them died off as he too suffered from the wasten the changed enviroment and gnetic defects transfered.Now there is little plants left, guppies everywhere, crap everywhere and even those guppies only living a few months still manages to find a partner to ensure their tainted gene pool spreads into the general population.We have no tank owner getting the balance right again, removing the sick and weak, we humans just keep going strong and if the crap pile gets too high we put grass and houses on top of it....We humans don't like to be compared with fish, a virus or any other lower being for that matter.These hings just don't affect or concern us.And anyone who dares to do so anyway has a long list of nasty words thrown at them.Is it because we humans can't tolerate the truth?Or is because deep inside we all know but refuse to think about it?

4 wheeled Quad-Cycle!

Has anybody made or thought about making an Instructable to make a 4 wheeled bike-like a car? I've seen them on the Internet for $3-4000. Thought it would be interesting because of higher gas prices.

In over my head - pH automation

Hi all,I'm in need of help. Due to my previous jobs and general knowledge a friend has asked me if I could build an automatic pH regulation system that will monitor and maintain two tanks (it sounded easy to me at the time) but I've suddenly found myself out of my depth.Having spent long evenings searching on the web and on here, I've seen a few builds of monitors and a couple of dosing systems but none are just what is wanted as they are only set up for single tanks, or not combined into an auto-doser, or too "over-tech'd" or multi-purpose orientated and I don't have the knowledge to adapt or alter things to my requirements. Plunging straight in at the deep end with no real idea of what I'm doing and can actually be done, I'm thinking I should be able to (theoretically) assemble and program an Arduino controlled system, with the one box doing the job of monitoring and regulating both tanks independently, so two sensors, pumps etc., from what I gather it's by adding different boards to the base unit (I did say I know nothing). I don't need wifi or anything like that, just a simple device with a basic display showing the current values that will sit there and just do the job.I think I have the capability to actually build and program the thing having a background in electrics and a little knowledge of relay control systems - not electronics, I start getting lost just after the transistor/diode level and BASIC is more my programming level (yes, I may be THAT old, but I'm still trying to learn), and so what would really help me is if anyone out there can point me towards a site or pages where I can find the info I need, hopefully that doesn't assume years of prior experience, to either build or adapt something to what I want, or even aim me towards someone who could be able to supply me a design and components list, either for fee or free. Cheers!

Very Frustrated - Instructable Won't Publish!?!

Okay, so I'm a professor and I have a nice project to publish.  For a first time user of this site, I'm thoroughly frustrated with the lack of detailed feedback when something is wrong.  I would fix it if it would tell me.  Usually I just walk away thinking that the thing is simply not worth the time, but the reputation of this site gives me repose to try to find out why. My instructable was saved and shows up in my drafts.  Great. I hit publish and it goes to a page to request keywords and category.  Great. I put a minimum of 2 keywords and select a category.  Great. I press "yes, publish my instructable" and the page refreshes, clearing everything I've entered. After doing this ten times with no other results or feedback of what the problem is, I find myself writing this topic in hopes somebody knows why.  Whatever the answer is to this dilemma, its kind of ironic that the instructable site is so lacking in basic feedback when there is a problem.. Oh well, I hope you understand my frustration.

Portable media build parts question!!

I'm looking to build a portable gaming and media station but I'm stuck on a couple things and am hoping people here might have some suggestions and/or links. Basically, I bought a large aluminum camera case, big enough to hold a 22" led tv in the lid. I am going to mount the tv in the lid, thinking of just drilling the holes and mounting the tv directly to the lid. Any critiques or problems with that would be nice.https://showbox.red/ https://downloadnox.com/ https://downloader.vip/vpn/

Rebuilding NordicTrack ski machine drive rollers

Many people still buy and use a NordicTrack Ski Machine, although these machines are not as popular as they once were. I have talked to people who say they just plain wore out a ski machine. The part that wears is the one-way clutch inside the drive rollers. NordicTrack makes the one-way clutch sound very mysterious. In reality it is a one-way needle bearing and is available from Amazon or locally from a good bearing shop. The internal diameter of the one-way needle bearing used in my machine (Challenger, similar to a 303) is 5/8 inch. The outer diameter is 7/8 inch. The width of the one-way needle bearing from end to end is 5/8 inch. I originally had hopes of being able to install new one-way needle bearings, myself; but, they together with the bronze sleeve bearings on either side of the one-way needle bearing inside each drive roller are pressed into place. Pressing bearings is not a job for the average home tinkerer but requires a bearing press capable of exerting tons of pressure in a very precise manner. You can often have a local machine shop press the bearings in your machine's drive rollers. Or, you can send them away to Nordic Track Guy and have them rebuilt for about $33 with a one week turnaround. The core of the rollers really does not wear out, but new rollers are available on the Internet from $65 to $95, depending on the vendor. From what I can find, some models used an alternate size. Check to be certain you order the correct rollers, if you choose to replace. One of my drive rollers suddenly began to hiccup. It seemed that the clutch did not always release immediately when I pulled my foot forward. Then I noticed a little mush in the response when I began to bring my foot back on the push stroke. Before you rebuild or replace your rollers, try this: Remove one side of your Ski Machine. See the second photo and check the exploded diagram in your manual. Four nuts and two screws, all plainly visible, need to be removed. Slide the washers and the roller off of the top side. The shaft and flywheel can be wiggled out of the other side without removing anything from that side. Remove the washers and the roller from that side, too. Flush the one-way needle bearing by squirting some penetrating oil, like Liquid Wrench, into the bearing. Work it both ways with your smallest finger. Push a facial tissue into the shaft hole in the roller and sop away the penetrating oil and any metallic dust it lifts. Do this several times. Let the rollers air dry. A little lubrication is good. People who comment on lubrication for one-way needle bearings use Tri-Flo (I am not familiar with it.) or they use a little ATF transmission fluid. You want enough to lubricate, but not so much that the bearings slip. (But, see the comments below where the oil impregnated bronze sleeve bearings are supposed to supply enough lubrication for the needle bearings.) Put the rollers back in place on the shaft. Check to be certain they grab on the rearward stroke and release on the forward stroke. Reassemble the machine. Do not forget the washers between the roller and the side board. My machine works again as it should. The day will likely come when this simple fix does not help, and I will need to rebuild or replace the rollers then. But, for now, my rollers have a new lease on life. What follows is for your information. The first photo is of a portion of the back cover of the manual that came with my machine. It shows a cutaway image of the drive roller. The black printing is mine. Notice the three cylinders inside the drive roller. The outer two are bronze sleeve bearings. The center one looks like a roller bearing, but is a one-way needle bearing. A one-way needle bearing is essentially a roller bearing, but the rollers are able to move forward and backward a little in their cage. There is a wedge shape for the axle of each roller that causes the rollers to bind between the bearing cage and the shaft when the rotation is in one direction, but they are free in the other direction. Here is a description of how they work with graphics. This link is for an Instructable about a number of modifications I made to our NordicTrack ski machine, including how it can be stored vertically in a closet. If you do not have a digital monitor for your skier, or need to replace one, here is an Instructable on how to make your own from a digital bicycle speedometer.  Check NordicParts for any parts you need, also Nordic Fitness Ski Machines. Danny at Nordic Fitness Ski Machines has some very nice new rollers for sale.

Has anyone made a solar heat powered Fluidyne stirling engine air pump?

So, I will start with what I have in mind.  (Might be total rubbish because I don't fully understand).  You have a solar collector box, not more than 1 meter square.  painted black 1 to 2 cm deep,   and probably with glazing over top. The box itself is metal fully closed up and the back is insulated.  From the box through the insulation there are some metal tubes that go to another box at back for the cooling chamber. Tubes are constricted so the air sprays through to the cooling box and it goes into steel wool as it expands. On the reverse stroke, it does not go so much through the steel wool because the nozel constriction is  on that side not the hot side.   Power is taken away from a liquid piston somewhere attached to both chambers  or a diaphragm at the back. (It can be water cooled). I want the strokes to be long and slow. Can it work?   Temp difference will only be around 40 degrees C and the pumped air ( 2 valves  in chamber off of liquid piston) only needs to go to 2 psi. )    I have been in contact with a guy in Germany who made Sterlings that worked with sun heat.    But he didn't use Fluidyne (also called liquid piston stirling) and he did not pump air.          My specs are extremely low, I only need 60 litres per hour of air at 1 or 2 PSI.  It would be very cool to make it from such basic materials.                 Thanks Brian

What is your glue preference for 3D prints

I'm curious to find out what glue people prefer to use with 3D prints, why, and how you use it to get the best results. Here is what I've tried and how it has gone for me. E6000 - good glue, kind of messy and takes time to dry. I usually squeeze some out on some wax paper and use a toothpick to apply it. Weld-On 4 Acrylic Adhesive - very liquid, have to transfer to a bottle to use, which for me requires a dropper, dries super duper fast so make sure it's in the right place when you push pieces together, can leave a white residue if it dries on your piece. SCIGRIP 16 10315 Acrylic Cement - pretty liquid, dries fast as soon as it touches plastic, I had to buy an applicator bottle to use with it and it doesn't work so I'm not sure if I need a different bottle or it doesn't work well with a bottle. not really usable for me right now unless I can figure out what to use with it. So when I have used it, I squeeze some out and use a toothpick to apply it but it dries as soon as I pour it out. I've also tried misc super glues but they tend to leave white residue for me. Currently, I would say the Weld-On is my go-to for gluing 3D prints, but I'd love to get other people's opinions!

"Open Link in New Tab" Issues

When you add a link within an "Ible, there's an option to have it open in a new tab. I like to add links to some of the tools and materials I use, and always check the box for that as I find it a bit irritating when the link takes you away from the page you're on.I recently was looking at one of my published 'Ibles and clicked on a link, but it doesn't open in a new tab. I went into edit mode, checked the open in new tab box, and went back to the 'Ible... same thing.I logged out and tried it again to the same result. Tried it in a different web browser just to see too.If I go into edit mode and check the box, save, go out of edit mode, and back into edit mode, the box is unchecked.Has anyone else had this issue? It doesn't affect functionality very much but is a bit of an annoyance

Suggestions for a beginner project bike?

I'm jumping the gun a little bit here, but looking ahead to winter and the off season, I want to find a cheap project bike I can tinker with. I have some mechanical inclinations, but it will be a bit of learning curve, so I want something that's pretty accessible and relatively easy to work on for a beginner. I'm looking for a cruiser anywhere from 250cc to 500cc with minimal bells and whistles. Lay those suggestions on me. Showbox Tutuapp VidmateAlso, what are some red flags I should look out for that are going to end up giving me nightmares? I want a bike I can work on and learn with, but I'm definitely not looking to do a complete rebuild.

Cultivating blackberries - works for roses too!

Although in many regions (wild) blackberries are considered to be a pest, in our gardens they can be delicious.I don't mean the wild variety here but the cultivated ones with big fruits and no thorns on them.And if you ever tried to successfully save money by just buying one and using cuttings from it for the new season you know the troubles....Creating cuttings from blackberries is quite easy if done the right way.But there is an ever easier and simpler way if you don't mind doing your pruning a bit later than usual.Once the harvest season is over and all berries are gone you see that the blackberries still keep growing before they finally start dropping their leaves.And if all went well then your blackberries have grown in long "snakes" supported on a vertical structure - like long bows.During a good season this bows get so long that they almost reach the ground at the end of the season.All you have to do it to free your snkes so you can places their ends into the ground, preferably out to the side so you can start a new row of blackberries with enough space between them.Use some soft cord and weights to keep the ends in the ground and fill the hole.Only water once when done otherwise let nature take care of things.In a very dry climate or season you might want to water a bit once a week though.When leaves start to drop in big numbers cut the above ground bits off with about 10 to 15cm left standing.Prune the big ones as you always do to get them ready for the next season.And when the next season starts you will see that most of your little "cuttings" take off like mad.They had the mother plant until it was time to go dormant, so no extra energy was required to stop a dying cutting from going dry.The end of the plant realised it is under ground and for that reason it is time to grow roots.Then suddenly it is time to hibernate and all energy is left in the remains, ready for use in the next spring.It is no problem to get over 15 new plants from a single one this way for the next season.It also works quite well fo roses.Although here you might need to create a podest or similar to place pot on.And the season for it is different too ;)It all starts with your pruning at thend of the season.All parts that did not produce flowers, those "wild" stems need to be fully removed.Those who produced good are cut back so you are left with 3 to 5 "eyes" - these tiny pimple where the new shoots come out.Pay attention to their location as it determines the direction of the new shoots ;)Don't have too many facing inwards.When the rose starts growing again in spring you should prepare your stand for the pot.The new shoots are quite flexible and can be directed to grow where you need them for the pot by using bonsai tape or wire - just be gently with them!Once long enough that the end can be placed about 5cm deep into your pot with good potting mix or the good soil from your garden:Place the pot so that the end shoot is held in the soilwithout force - if in doubt let the shoot grow a bit longer and form it donwards with wire.You want to bury it only when there is new growth going out if it but not of the end currently only has the leaf(s) showing.These fresh end shoots should point downwards into the soil.Cover it all and keep the soild moist at all times but not soaking wet.It really helps to have the pot shaded.You can use small seedling pots and check for roots a few weeks later or just wait till the end of the season.Either way a root should form in the pot and once strong enough you only have to wait and look out for eyes forming on the stem.If the do you can cut the stem so you have enough eyes on the potted stem.Be aware though that this will only result in a strong and healthy rose if the mother plant is not a hybridised clone.For the later it is best to transplant and eye onto a donor bush or wild rose.

Quirky tip on how to propagate roses?

Recently I found this little quirky tip on how to propagate roses/ bushes and I was wondering if it was true? In the little tidbit, they tell you to use a cutting of a rose of course and then put a little cinnamon on one of the ends that you intend to grow roots. Then poke that end in to a potato. Then bury that part with the potato into the ground. After I guess eventually you get a new rose bush. I was wondering can this actually work? Or is this just bait to get you to read more of their articles?

Extemely simple automatic emergency light.

I'd like some help to settle an argument regarding my extemely simple automatic emergency light.According to my friend, who installs emergency lighting, this circuit is too simple and has too many components missing but I say he's wrong, if one part fails it can easily be replaced. I'm not and electronics expert either.I'll explain the circuit...5v comes from a 5v 2A phone charger. Battery is a 32Ah 12v SLA. 12v charger is a smart charger with built-in status monitor.SPDT 5v relay rated to switch 12v @ 17amp maxThe light is a 12v 5 metre LED Strip with built in current-limiters and draws arount 2A.Basically, 5v powers the relay which means the battery is connected to the smart charger that keeps it topped up while there is mains power (240v here in UK). If there is a power cut the relay turns off and battery is switches over to the LED light Strip. Its that simple.It works as designed, no parts have failed and I haven't found any signs of over-heating. My friend believes it should all be one circuit and not seperate parts and is a fire risk as it is.He just won't let it go, so does he have a point or is he just being a/an _________ (fill in the blank, lol)? I've included a schematic of the circuit. Not sure if I've drawn the relay properly though.

Elevator or counterweight lift beds

Can anyone reverse engineer and make one of those elevator beds that are made with counter weights? They are becoming popular in Europe.  Ana White made one using garage door but it uses four corners.  The ones in Europe use only one wall or also add the ceiling across for the other end.  I like the one that spaceurc_com has which uses counter weights. BedUp_fr & espace-loggia_com seem a bit more difficult.  I can build a murphy bed, but these are a challenge and I like a challenge but it is too technical for me. Thanks for your help.

How to deal with sap in christmas tree trunks you want to use

I had an idea to re-use the trunks of Christmas trees my neighbors are throwing away. I sawed off the thick part of the trunk and removed the branches from it. But now I have lots of oozy sap that makes the wood sticky and unpleasant. Any suggestions on what to do? If I stain it or coat in polyurethane will that prevent more sap from oozing out? Ideally i want to slice one trunk into coasters/trivets, keeping the exterior bark intact. The other trunk might become the base for a side table or something similar. Or maybe I'll just hollow it out like a cup and use it as a pencil holder. Thanks for your help! Josh

Please Help for AutoLevel TronxyX5S

Hi, I apologize for the corrupt English first.I have a Tronxy X5S 3d printer. And I bought a sensor( SN04-N NPN) to add autolevel property to the printer. I thought I would be able to get rid of the small curves on the hotbed. I've arranged my commands according to autolevel as follows. But when I want to print a large shape, the extruder remains in the air at some points of the hotbed, print properly at some points, and at some points worth the hotbed(no filament output). So the autolevel property is not working properly. Can you help me?
