  • Fully Adjustable DIY LED Grow Light and Grow Box - Complete Light and Cabinet Build (all Under £300!)

    Where did you get your wattage and color layout plan from? I have been looking for the theory/math for an LED grow light system that works with seedlings then flip switch and color plan changes to growth/flower. Your Led color layout seems to planned for random, so I was just wondering where your science in it came from.

    There is voltage and there is amperage. Think of a garden hose, the pressure of the water is the voltage, the flow of water is the amperage. Resistors can affect both, but it is how they are hooked up that does it. Mostly, they affect amperage. if you kink the hose (kink is resistor) there is still the same pressure (voltage) but the flow is limited. Now, if you had two kinks but a T connection between the two, then the pressure at the faucet is still high, say 100psi (volts) and can flow at 10 gallons per minute. the first kink still has 100psi but reduces the flow to 8 gallons per minute. the 2nd kink still has 100psi but flow is at 6 gallons per minute. All this does is affect the flow (amperage) BUT, if we put a tap inbetween the two kinks and add a new hose, then the pressur...

    50psi on both hoses, and the flow is still 8gpm at the first out hose and 6gpm at the 2nd. If we change how much the kinks are, then the flow (amperage) and the pressure (voltage) changes between the two. it is quite simple, if you can put it into a perspective of which you can imagine.100psi @10gpm ---------~~------T------~~----------------------(50psi @6gpm) I I (50psi @ 8gpm) I (100psi@8gpm)

  • I prefer to use the solder sucker. For a cheap find, just go to the baby isle at your closest 'Evil Empire' and get the bulb for sucking ears and noses. https://www.walmart.com/ip/Infant-Baby-Newborn-Bulb-Ear-Syringe-Sterile-In-Package-Soft-Latex-Free-2-Oz/488576349 I have several of these and they work just fine &&& don't cost a premium for packaging that says specifically for solder.

  • Homemade Tin Can Turbine With 3d-printed Compressor

    Not really. There are way too many variables. The proper way is to put it on an engine sled. One that has extrememly little resistance to linear movement. Then mount the engine on that sled and attach your measuring device to the sled. For gross measurement, a fish scale would work, but if your planning on flying it in RC, then you would need something far more accurate. THis is about the only way to get a real measurement of thrust. The mathematical way you are talking about only gets you close. From there, you can add more blades of finer size/distance to compress the air more or add a larger intake or a smaller exhaust. But shy of the sled/scale, you wont get anything accurate enough of a measurement of thrust other than ballpark. I have built several small turbine engines as w...

But shy of the sled/scale, you wont get anything accurate enough of a measurement of thrust other than ballpark. I have built several small turbine engines as well as rebuilt, PMCS'd and maintained older helicopter turbines for racing boats. We always had to use an accurate sled. Even A&P folks do it that way. Maybe not to the gram with the real deal since they push many pounds, but same thing. small engine - small scale; large engine - large scale. Lastly, YES, I know. The turbo-fan jet engines on helicopters actually use the main shaft to turn the transmission to turn the main rotor and tail. If you make minor changes to the engine so it pushes air instead of power and speed to a shaft, then the same engine can push a vehicle, just not as efficiently as spinning a shaft on a rotary wing or an impeller in the water.

    Basic Gear Mechanisms

    check out https://woodgears.ca/gear_cutting/template.html I use this to design and print all of my gears that I end up cutting out of wood via a bandsaw and scroll saw.

    Non round gears is a multi step process. First, you want to find the shape that you want, it can be almost anything but don't have your lines come back on themselves, ie, always go forward with your pencil, no back wards drawing. lets use a square for example, Next I use a online utility that I posted a link to in several replies in this 'ible. and I create a design of a rack and pinion using the size of teeth I like. Next (3) I print out the rack portion so I basically have a straight edge of gear teeth. Next (4) I start at one edge of my square and with the top of my teeth-edge lined up with the edge of the square, I trace my teeth onto the square. at the corners, you need to pay attention to the size of the spacing when you trace around the edge so that the width of the tooth ...

Next (3) I print out the rack portion so I basically have a straight edge of gear teeth. Next (4) I start at one edge of my square and with the top of my teeth-edge lined up with the edge of the square, I trace my teeth onto the square. at the corners, you need to pay attention to the size of the spacing when you trace around the edge so that the width of the tooth or valley is consistant with all of the rest.After the teeth are traced on my first template, then I cut it out with a scisors. U like to use a thicker acetate sheet like the old overhead projector sheets. Next, I take that template and bring it to my next shape and as I rotate my first one, I am tracing the teeth onto the next. The trick is, your basically putting the pencil edge on the very tip of the tooth on your first template and as it swings around inside of the line on your second odd gear, your tracing the valley of the 2nd gears teeth. Then back them up to the point where the next tooth touches the line and then trace its center.this is a lengthy but simple process and in the end, you get two crazy looking gears that will mesh correctly. I will see if I can find a video on it as I know there are many. These two videos don't show quite what I am describing, but they come close. I will try to make a video for you when I make my next set of templates. enjoy https://www.youtube.com/watch?v=v-GPfgQ_c2k and https://www.youtube.com/watch?v=iTeOrCxqzBs

    Follow this link https://woodgears.ca/gear_cutting/template.html and read the stuff at the bottom of the page, It explains What; how to find; how to calculate; and design the different parts of gears such as Tooth Spacing - Contact angles, spokes, pitch diameter, line of contact, plate mode, etc. BUT, to answer your question directly: The pitch diameter is the effective diameter of the gear, so to figure it out, draw a circle around your gear but the circle goes in the middle of the teeth, if your teeth were 1 inch long, then that circle would go thru the teeth at the 1/2 inch mark. That circle is your pitch diameter of the gear. follow the link and read.

  • Everything You Need to Know About Tanning Animal Pelts.

You want to use the alum-borax to process the skin to keep it from rotting or getting eaten by bugs.When you get your form, I will use some alcohol to wet the skin so I can work it, though not wet- soaking. just enough to soften the skin a little.Once you folded and pinned your fur on the form to verify proper size form, then tie the fur over it to let it dry again. It will be stiff, but then you can work it off the form and continue your glue down and taxidermy process.It is worth it to take taxidermy classes, even if only online. part of a good taxidermist is to find you own processes for skin-fur-feather-scale processing. Taxidermy is far more than just slopping a skin on a form.

    putting your hard skins in a big tumbler with hard balls and turning it for a few hours will work quite nicely too. If you can get a 55 gallon metal drum, then you can make a good tumbler for cow/cattle skins. Ive make a metal drum into a bulk fish scaler by pounding hole into the drum and tumbling in water. making a base with some cheepo wheels from harbor freight and a big riding lawnmower belt with a 1/4 hp motor is not only cheep but works wonders.forget the shoulder busting branch breaking method, process the skin and tumble it. it is how the commercial industry does it and for good reason.

    I know this is old, but good for future....If you want just the leather, your hide is fine. If you want a fur, then it is toast. The best thing to do is to always salt the heck out of it, then roll it up and stick in freezer until you can process it. I usually roll mine into burlap so the freezer can help dry it by way of evaporation. if it is in a bag, it cant get dry very well while frozen.I find commercial products to be easiest as they have everything there and instructions with better pictures to follow than this .. rehashed . not much for experience . ible.

Personally, unless you did the work and can show it, you shouldn't be posting an ible. taking info you took from other sources and rehashing it out is not the point of this website... just my opinion.The turpentine way works quite well for small furs. Mine usually come out stiff. The author eluded to parts of the finish work on furs but from lack of doing it, never finished this ible.Once you have processed your furs, you put them in a big drum, or in my case, a 5 gallon bucket with a lid, as well as sawdust, some rubber / plastic dryer balls and tumble them for an hour for small or 2 hours for larger furs. The point of this is to beat up the skin and make the whole thing very soft and workable. I use 2-1 by volume of sawdust to fur skins. 4 balls per square foot of fur. after tumbling, I will take out the furs and check them. if the skin is soft enough for my needs, then it is done, if not, it goes back in for another half hour at a time until complete.then you just shake off the dust, vacuum it till nice and clean. You can wash them if you choose, but make sure you dry them completely as fast as you can, the skin is now tanned, but it can still rot if wet for too long, or it will/can dry hard.Do your own research or read the instructions from a commercial package. This ible is almost useless and will leave you with a rotting, stinky, chemically scary mess. It is not complete enough to properly process a fur.Sorry if I offended anyone - truth hurts.

  • How to Create an Amazing Workspace at Home

    i learned that lesson the hard way, I have had a finger ripped off of my gloves from the table saw a few times. Now i have tight fitting shop gloves. I will still wear gloves, but only form fitting. The ones she is wearing in the picture with the mitresaw most definately are not the ideal route to go.

    impressive work. I have spent the last year looking at other peoples ideas and designs for my small shop. I need one part dedicated to small gas engines as i like to rebuild 2cyl snowmobile and jetski engines and 500-700 cc motorcycle engines and the rest for woodwork. Your glued wood work surface keeps coming up as ideal, and your process that you used looks the most simple. I saw your other videos, WOW, you put a LOT of work into that. I am incredibly impressed. I would have thought you used a router for flattening the counter, not hand plane and power planer...I am impressed.

  • 37 Unusual Uses for Lonely Socks

    This one is funny as they get. Some really great ideas too. I keep a bag for all of my orphan socks or ones that I won't wear anymore. I typically use mine for polishing the fine flatware or for polishing chrome and aluminum parts on the motorcycle. Then when I'm done, I just throw them away. I don't like cleaning a washing machine after cleaning oily or otherwise chemically contaminated rags. Thank you for the great instructible

    My kiddo does that. She prefers non matching brightly colored under armor type of socks but I think the whole point of the instructible is to just have fun and repurpose items we would just otherwise toss out.
