  • 3D Printed Spinning Percentile Dice

    This is a really cool concept, for me this would not be practical as it's spinning takes to long, and the Guys I RPG with would all start complaining very quickly at how long it takes (this is kind of an interesting contrast to the way it was when we played as kids. To mix it up a bit, how about considering putting this die set mounted firmly on a support and put bearings on the spinners and use it like a roulette table type of Die set, the platform wouldn't have to be large at all, and could still fit in your pocket.....hey I might try making something like this too, except my printer is on the fritz, but I really like this concept! You could make it with a center pin like you have now, only have two gear rings on it and the inside of the Spinners and you could also make it so that the c…

You could make it with a center pin like you have now, only have two gear rings on it and the inside of the Spinners and you could also make it so that the center pin needs to be pulled up for it to engage the gears on the bearings' inner races. after spinning the pin would simply fall down and then they can free wheel at the speed which friction will slow them down the two spinners would slow at different rates because of spinning mass being different and also the quality of the bearings would also be a factor. Just a suggestion, I have a 3D printer myself but I'm having serious problems with it and I'm not optimistic about getting it working. Anyways, great instructable. And a really cool concept for rolling percentile! Keep up the work my friend (ha! As if this is work LOL).

  • Ixodida Death Cylinders – IE, Tick Prevention Tubes

    Yeah, Squirrels and chipmunks both carry nasty diseases! I suggest you engage in ridding yourself of those cute little vermin as soon as possible. The culprits are the Ticks and Fleas, that are basically dirty hypodermic needles and the Diseases carried by either of these rodents and their accompanying insect parasites, are, but not limited to Ringworm, Tularemia, Typhus and Bubonic Plague. All of these can be carried by both rodents because ticks and fleas aren't picky about the blood they get. I would consult with either a exterminator or the local health authority in your area that can give you more information. Best practice is to get your pup a tick and flea collar or medicine that you apply to your pet directly, but if you have cats as well, then you should consult a veterinarian as…

Best to take care of the problem as soon as this Wuhan virus stuff dies down.

    I would suggest to anyone who has tick or flea problems to use Diatomaceous Earth, it is basically nothing but dead desiccated fossil remains of Microscopic organisms. They ate so sharp the when an insect walks through it, the "earth" gets all over them. and as they move and flex, the Diatoms cut their way into the soft connecting portions of an insect's exoskeleton, and when this happens the insect begins to dehydrate at a massive rate, much faster than it can compensate for, and they die that way, or other more invasive microbes or bacteria or virus can find it's way into the insect's body through these cuts, and it can die of various diseases or from a parasite as well.

However, if you have a microscope or access to a microscope, put a tiny amount of diatomaceous earth on a slide without a cover (be careful to not breath in Diatomaceous earth or it will harm you), set it to the second highest setting you have and you will be treated to the most spectacular sight you will ever see! Search out "Diatoms" in Google and have a look, you'll be amazed and with you could have one of each kind! (Note: Diatoms are so plentiful and the designs of the shells that these creatures left behind or pretty much unlimited, meaning we have not idea how many different kinds there were because we haven't found the end of the shapes yet)

  • "The George" Liverpool's Liver Building Clock Replica

    What a beautiful designed clock dial! No wonder you wanted to build it! I'd say you accomplished it with flying colors! The warm yellowish light adds that classical aged feel to it that makes it much more beautiful dial to look at, way better than a cool light would. You sir, have done a fantastic job, I would build this too if I had room and tools to do so!

    The Light Badge

    Really handy things you created! Something that is useful for people! The best kind of creations are the ones that benefit those around us! You've created a light that doesn't need to be told to turn on and what is more is that you could make so much more with this kind of thing, you could make this circuitry as part of an outdoor light system that turns on as the sun sets, great for a basketball court or tennis court or any other application where light is needed, like on a patio for a pub or restaurant! Keep on developing your skills, and you could start to make a living out of making! All the best wishes for you my friend, never stop creating!

    Respect! This is a seriously cool gadget. However, I have to agree with caitlinsdad's comment about the battery. You really don't want the electronics strapped to your legs! In particular, the Lipo battery. Those things are seriously volatile and would do a catastrophic amount of damage to your thighs in no time at all, truly a matter of a second or two, and the heat is well above what a human can tolerate. Cute as it is, please relocate your electronics to a pouch or fanny pack with quick connectors that you can yank out in case of a catastrophic battery failure, and be able to move away from it without it being tethered to your body in any way. Seeing them strapped to your legs was truly amusing, but you don't want to be permanently scarred because of an electronics experiment gone bad.…

    Really cool idea, and it's so nice to have the light and the sound of a fireplace, I could repeat what others are saying about using an arduino or something else for sound, that's a cool idea, I think it might be worth trying! I just have to say that the picture of your dog in front of the fireplace, all I can hear in my head is that the dog is saying "dere's lite, how come no heet?" with a dejected inflection in the question, since all of the dogs in my family loved laying down in front of the fireplace to stay nice and warm.

  • DIY $5 Heated Chicken Waterer

    I've tried to use an aquarium heater, and they are meant for indoors use, they fail really quick when they are exposed to the elements and the constant jostling and pecking that hens do. Best to use a container and heat the container like this with a light bulb or if you have the knowledge, a heating wire with a thermostat. However, what works for you is what works for you, and I'm a big believer in the statement "if it ain't broke, don't fix it". So do what works best for you because there are many ways to skin a......polecat. LOL

  • Chefs Knife From Welding Electrodes

    You have a good eye for lines. The shape of your knife, although unorthodox, flows quite nicely and the way you have the cutting edge right to the heel, proves that this will be a working knife, for anyone who's eve tried to cut food in the kitchen with a knife with a dull heel is a pain in the butt! Your knife doesn't have a dull heel, and that is one of my prerequisites for s functional knife. Great Job! I love the handle and the little flare at the pommel end! Keep making things in your way, you've made me a believer out of me, I thought a welding rod knife would be filled with micro cracks and would have a short working life, but your blade is very nice indeed! Keep up the good work!

    Tin Can Pancakes

    Usually there are no plastics on the outsides of tin cans, the ones with pull tabs on the top can have plastic coatings on the inside though, so there isn't much worry they are eating melting plastic. However, the cans that have the plastic on the inside will release a black acrid smoke, and that will poison peoples lungs, if they breathe it. If the smoke gets onto the food cooking on the outside it will make it unpalatable. I used these in Scouts a very long time ago, and there was no worry of plastics in cans back then. We cooked our own hand made hamburgers on them when out in the middle of nowhere. Nowadays the people who are making these will be able to tell if there is plastic inside or out, and simply not use them. Just use the tall, bigger tins that Tomato juice still comes in, th…

Both work very well and are safe to use.There are no health concerns with photoelectric smoke detectors because no radiation is involved. Photoelectric smoke detectors sound an alarm when smoke particles scatter a beam of light in the detection chamber. They respond quickly to fires with lots of smoke.Ionization chamber smoke detectors contain a small amount of americium-241, a radioactive material. Smoke particles disrupt the low, steady electrical current produced by radioactive particles and trigger the detector's alarm. They react quickly to fires that give off little smoke. Ionization smoke detectors expose people to a tiny amount of radiation—about 1/100 of a millirem per year. This is well below the background radiation level of about 360 millirems a year. If a smoke detector contains radioactive materials, a printed notice on the packaging will say so.Because of the long half-life of americium-241, the amount of radioactive material in an ionization chamber smoke detector at the end of its useful life will be about the same as when it was purchased. State and local requirements for disposal of ionization smoke alarms vary. Some States conduct an annual roundup of ionization smoke detectors similar to that for hazardous household chemicals. Others allow ionization smoke detectors to be thrown out with ordinary trash but recommend that used smoke alarms be returned to the supplier. Some States require that used smoke detectors be returned to the supplier. Check with your local solid waste district, hazardous waste program, or health department to find out the procedures in your area. All manufacturers of ionization smoke detectors must accept returns—when in doubt, return the detector. Return addresses are listed in the product warranty or use instructions.Smoke detector batteries should be disposed of as explained in What should I do with dead batteries?Health Issues: Radiation can cause cancer and other problems, including defects in unborn children. Radiation produced during normal use of ionization smoke detectors is so low it has no noticeable effect. If the ceramic chamber containing the radioactive material is removed and swallowed, exposure is about six times the desirable yearly exposure—still too low to cause acute health effects." https://www.fs.fed.us/eng/toolbox/haz/haz25.htm

    I just found another possibility regarding your geiger counter and higher readings than background radiation. The long and the skinny is that geiger counters are not useful for accurately measuring low dose sources of radiation. here's the quote and the link to the page. "... when it comes to understanding some of the limitations of Geiger counters – it helps to understand that alpha particles have a lot more energy than do beta particles. It also helps to understand that radiation dose is a measure of the amount of energy that’s deposited by radiation in an object – more energy means more dose. So looking at this graph, we can see that high-energy radiation hitting a detector leaves a bigger signal than does low-energy radiation. Now look to the right, in the Geiger-Muller region – …

It also helps to understand that radiation dose is a measure of the amount of energy that’s deposited by radiation in an object – more energy means more dose. So looking at this graph, we can see that high-energy radiation hitting a detector leaves a bigger signal than does low-energy radiation. Now look to the right, in the Geiger-Muller region – in this region the high-energy radiation produces exactly the same signal as the low-energy radiation. So we can’t tell the difference between high-energy and low-energy radiation, which means that we can’t necessarily tell how much radiation dose a person was exposed to if we’re just measuring with a Geiger counter. This is one reason that we can’t always use a Geiger counter to measure radiation dose rate accurately. If a Geiger counter, for example, is calibrated to measure radiation dose rate from the radionuclide Cs-137 it will be right on the money as long as you’re trying to measure radiation dose from this nuclide. But what if you’re trying to measure radiation from cobalt-60 (Co-60)? Well, then you’re in a bit of trouble – radiation from Co-60 is twice the energy as radiation from Cs-137 so whatever your detector reads will be only half the actual radiation dose rate. On the other hand, a lot of radionuclides are lower-energy; in this case, your meter is going to read a higher dose-rate than is actually the case. The bottom line is that a Geiger counter will only give an accurate radiation dose-rate reading if it’s measuring the same radioactive material it was calibrated with. This is why Geiger counters aren’t always the best instruments to use to measure radiation dose rates." link here: http://www.ntanet.net/how-do-geiger-counters-work

    The radiation source in ionization chamber smoke detectors is sandwiched between metal foils, which keep the radioactive material well contained.The tiny amount of radiation that can be measured outside the unit does not pose any health risk. In fact, the average annual radiation dose a person receives from a smoke detector is 0.01 percent of the dose they receive from natural background radiation. this is an excerpt from the Canadian Nuclear Safety Commission. further information can be found here: https://nuclearsafety.gc.ca/eng/resources/fact-sheets/household-smoke-detector.cfm

My government strictly regulates all radioactive materials and perform over a hundred tests on these devices to make sure they are safe. the detector you tested should be reported immediately it might be a breech of the regulations the UK has on them. either that, or the Geiger counter you used is out of calibration, and they need to be calibrated. Also, Geiger counters have a limited service life and it is not recommended to use them after that date. myself, having used several geiger counters at University (Nuclear Medicine), it is highly likely that the latter is the case rather than the former, Since Americium is so expensive and labor intensive to retrieve from Nuclear reactors, I don't think someone is going to deliberately nor accidentally put too much Americium in a source for a smoke detector. Most School Geiger counters don't need calibration since the lessons taught are of a empirical nature, meaning it's just good enough to show that there is radiation coming from whatever it is they are testing. Things like that are heavily regulated and when rules a breached, it means laws have been broken and usually prison time enues, so no one is going to be negligent when metering out minute amounts of radioactive Americium 241. Most people I know also do not wish to harm others and when in such positions of employ, take extra precaution when working. Much like Nurses, doctors, Surgeons etc. do when they work to improve people's health. https://nuclearsafety.gc.ca/eng/resources/fact-sheets/household-smoke-detector.cfm

Here's what My government says about these devices: "The radiation source in ionization chamber smoke detectors is sandwiched between metal foils, which keep the radioactive material well contained.The tiny amount of radiation that can be measured outside the unit does not pose any health risk. In fact, the average annual radiation dose a person receives from a smoke detector is 0.01 percent of the dose they receive from natural background radiation."https://nuclearsafety.gc.ca/eng/resources/fact-sheets/household-smoke-detector.cfm

  • I love it when people add Origami to their projects! I have practiced Origami for nearly thirty years now, and it has only been since the start of the 21st Century that I have noticed lots of young people practicing it as well. Origami is such a beautiful artform and to see it getting this kind of exposure, it just makes it a much broader known artform and people get involved in it. I wish that schools taught it just like in Japan! there is no Japanese person alive, who grew up in Japan that DOESN'T know how to fold origami models. It helps children in many ways that people don't understand. and there are too many to list here. Anyways, Great Job, it is Both Beautiful and elegant in design and truly captures the beauty of Origami! Fantastic Job!

  • This has to be a awesome example of a Father's Love for his children! I never had the kind of skill and knowledge base to do this kind of fun with my children, but I have always wanted to help my children learn and grow, I wanted to be a channel through which true knowledge flowed from me to them, and I have always done my best to be that for them! A Father's Love is so very much different than a Mother's. They need both to help them the best, but you sir, have exceeded all expectations as a "cool Dad"! Well done sir! I salute you! However, if you think your fun with your boys is over, you might be right, but when your grandchildren start coming, the fun you'll have them will beat the fun with your son, hands down!

However, if you think your fun with your boys is over, you might be right, but when your grandchildren start coming, the fun you'll have them will beat the fun with your son, hands down! Being a grandparent is super awesome, so keep yourself fit and healthy, because Grand children who grow up with a healthy relationship with their grandparents become more adjusted and more stable in our society, because they learn love and respect for their elders and that they also learn that grandparents are a deep well of stories inside them so when they come over for sleepovers, telling them bedtime stories from your life is an awesome way to send them to bed! Yes sir, grandkids are awesome, can't get enough of them!!!

  • Great Instructable bro! The result is really cool! Is there a way to change the color of the display screen to black instead of blue? The screen is still slightly visible with the screen having a blue background. Other than that, it's a superb idea! You could even put in on the side /top or bottom of Larger mirror hanging on the wall!

  • Your instructable is really good, one thing though, you don't have the Pi camera listed in the parts. Are they including a Pi camera when you buy a Pi 3B or 3B+? I'm also fairly sure you could use a Pi 2B+ and a 3rd party touch screen, you would just have to make sure you have the Drivers, right? Let me know if I'm in error on this. Love the way you set up the camera. You could have the camera connected by wires to the printer, say in a case with a cover? So you can take pictures with the Pi and camera assembly, and the printer is in it's own case protected from the elements while it print thems off?

  • OculumForamen commented on brownewepr's instructable Cardboard Pen

    Just to add to what AeroSpaceWatercraft has said, you can go to a local Medical supply store and buy yourself syringes of the size and shape you need, but you can also get the metal needle section used to pennetrate the skin for injections, this will allow you to inject each and every flute with the resin, and for basically pennies per piece you don't have to worry about thowing them away after you're done. Also maybe try doing a number of sections of cardboard but don't epoxy them together, but do that later, after each flute in the cardboard has been filled. Then place them in your blank molds and do as you did before. However, this may make the project so overwhelming that it isn't worth it. you may also get a lot of people under valuing your results because they don't know how hard it…

You might want to try other methods to use cardboard, say....like a paper maker does, and reduce the cardboard to a pulp and then mix it with resin that way, etc. etc.. Just making a suggestion. but your idea is really a good one, and the result seems to be quite striking, keep up the great work! I've made pens with a lathe many times and I know the work that goes into such projects, especially when things don't go as planned.

Anders644PI, you keep makinng th8ings the way you want to make them and call it anything you like, you have the God-Given right to do so! I think your build was particulary cool, because it actually resembled a TV I once owned! I totally appreciate the irony of having a microcomputer in the shape of an old TV (which is what I used to hook up my console games to when I was a teenager! Making it even more appropriate, because no one would be able to use those old console games without a TV being involved!) so full points for your build dude! and when someonne starts to criticize your work for no good reason, is usually because they are jealous. My challenge to people like that is to tell them to build their own, that way they can name it whatever they want, but your Name/Title is what you chose, why should you change it? keep building my friend!

  • No problem. There is another instructable that goes over balancing 18650s, but I can't remember who it was. It might have been on you tube also, but you need a special electronic device that I don't have. I have seen Litium cells fail, and there is no way that I was going to carry 4 of them in my pocket! Even being close to one when it fails is a bad idea! So yeah, be careful witth those used cells! But the kit you bought is totally cool, I may order one too, if you can convert them to use NiMH or NiCad AA batteries. I just need to mention that even new cells should be balanced to make your project function at peak performance, so, that is what stops me from using them.

  • I have a few 18650's around my mess of a shop, but I have to say that I use NiMH rechargeable AA battteries in my Power Bank. I have been using them for some ttime, and I haven't experienced any problems or significant loss of recharge time over the last two or so years. This is a much safer alternative to lithium cells like the 18650. Especially if the lithium cells are used, there can be some serious problems with used 18650s, and keeping a power bank in your pocket or in a back pack can result in serious injury to you or others near you. Because of this, I stayed with the rechargeable AA batteries and making a power bank out of them is super easy, since once the power bank is condstructed, you can use regular AAs in it if you run out of rechargeable power. If you make the above project…

If you make the above project with used 18650s, make sure that they are balanced with the others, or you run a higher risk of failiure. Just sayin', other than that, this is a cool project, it would be worth it to use new cells in it, that way it will have a good long life. Adafruit industries has excellent cicuitry for power banks.

  • This is how companies make money. Society has been one of a "throw it away, when it breaks and go buy a new one" Mentality for some time. The best way to combat this is to return the item for a new one, but it seems that people can't be bothered to keep the model they bought; nor are they happy to spend the time doing it, but they don't mind spending more money to but a new model! The company that makes these things is at a bit of a impasse. They have to use decent quality products, but they don't want their item to last that long in their business model, so they use good quality components, but then they do this kind of thing. They increase the power to the led but run the fans at max to keep it cool, because they know that as their life goes on, they will eventually slow down …

This is what we call Engineered Obsolescence, and it is the business model of many many companies! Thank Goodness that there are people like you, nume1977, who can trace electronic circuts and understand what is going on inside, and make improvements to it, thereby defeating the incorporated Failures built into the system. I am not under any illusions, if a recular citizen can trace an easy problem with something like this projector, that this company is guilty of only making a mistake. No way, the did it deliberately! Thank you nume1977! do you have a blog or vlog that you normally do on you tube if so I'd like to subscribe to it!

  • well done! I think that your ARC reactor is one of the best ones I have seen. The wire wrapping is an nice added touch, the more detail you add, the more realistic the unit will be! You deserve to be given lots of attention for this project because the effort you put into it and the overall effect it has!

  • I have a screen from my mother's old Laptop, and it would be perfect to make one of these! Thanks so much for the 'ible!

    It would be nice to have a nice sultry voice to say special Phrases that match a number of sayings for the screen. That would make it great for my wife. Now if I could just get Benedict Cumberbatch to be the voice of the Raspberry pi then I could sell millions of these! My wife would be Customer #1 ! LOL

  • I intend to distill catnip for the purpose of creating insect repellant, since I am Immunosupressed due to a liver transplant, I need to keep away ffrom Mother Nature's flying dirty needles! With the small amount of distillate that you have created, how much repellent would that create? I have no idea what the concentration level I would need to create so that I could use it as a spray repellent. Do you have any ideas on that?

  • Yes, actually. Google it. Catnip contains nepetalactone, which is 10 times more effective as a mosquito repellant than DEET. DEET disolves car paint! I used it every day when I was a teenager riding with my dad for work, and it softened the paint on the inside door sill where I always rested my arm, to the point I could scrape it off with my fingernail and it would take it right down to the metal! If you use a lab still and a hydro bath condenser, you can harvest the oils from the cat nip, and add it to a cream or a water spray and use it that way. Just growing catnip and rubbing it on yourself will not work. It's really not that hard, you just need to know the basics and have the components for a lab still. :)

    Ah...but did you destill it and concentrate it using a hydrobath condenser? Once you capture the unadulterated, concentrated form of catnip, I'm not sure if it's an oil or a hydrous solution of some kind, but deet has been proven to be 1/10 as effective as DEET. My previous number was wrong, I had mis-remembered. Google it, I'm gonna try and find the lab aparatus I need to harvest the Nepetalactone ( the essential oil in catnip). I need to keep away from Mosquitos as much as possible, I'm immunosuppressed. That way I can keep away from Mother Nature's dirty needles!

    This is perhaps one of the most beautiful little "chest of drawers" I have ever laid eyes on! Your inginuity and execution are amazing! Whoever you made this for....I bet they show it off every chance they can get. Have you entered this item into carpentry contests? If not I urge you to do so, this is that good of a project! You must have many years of carpentry experience.

  • Years ago my mother and sister had gone on a trip, and they had an incident that made them need fire to be able to cook and eat something, and from then on My Mother has asked me to make sure I have a fire kit in my car. I always do! These are a great labor day gifts for us Canadians, since that's when our winter usually starts! making your own fuel is actually a better idea because you know how they work and can make more as needed with only minimal supplies. There are other instructibles that teach how to make your own longer burning fuels to make sure your fire get started!
