I need a brush that has a basic shape, like a leaf: an oval with two points. I also need it to alternate between several shades of green. How hard would this be? I want it to alternate automatically. I'm using this to kind of do a "weeping willow" effect.

If you have been flying your RC planes a lot and have found them getting a bit boring, go brushless and get lithium polymer cells. brushless motors are lighter and twice as powerful as brushed. lithium polymer batteries hold the most electricity to weight ratio compared to standard Nicd and Nmh. Dont believe me look at your cell phone open the battery hatch and take out battery its probably a Lithium polymer or lithium ion notice how light it is and small it is now look at the volts/ mAH pretty amazing hu? Got a laptop it probably got a lipo to. you want to make the switch but dont know what motor, battery, ESC (ESC-electronic speed control) to get, just ask and ill give you a hand! i will need to know the motor and battery that came with the plane/ or that u are using. Are you flying glow (gas powered) and wana go electric? i can help u out their too! Their are 2 kinds of brushless motors outrunner and inrunner whats the difference? well outrunners spin slower with more power so it acts like it has a gear box (this eliminates the need for a gear box reducing weight and noise) it also has a different design (look at pics). inrunners have a brushed appearance but their much lighter and more powerful u might need a gear box through. update 2/20/08 new image added (not all comment boxes are working)

I've found some glow in the dark paint, which I'm going to use to paint my bike frame. The problem is that its brush-on not spray paint. I really want a glow in the dark frame, and I can't find any glow in the dark spray paint. All the bike painting instructables use spray paint. Does anyone have some tips on how to do a good job with a brush?

Years ago we used to make and sell specially designed brushes for stopping wool from being lost off shearing shed boards when shearing sheep. "Lock Stoppers" we called them. The brush would be mounted with bristles up at the entrance of the chute the sheep goes down after shearing. The brush would catch the small bits of wool (locks) but allow the newly shorn sheep through. They sold OK when the wool market was booming, but those days are gone and we now have piles of these brushes gathering dust. Does anyone have any good ideas for using them for something fun or creative? Does anyone want any of them? They are each about 500mm wide. The bristles are about 200mm long. The brushes are about 5-10mm thick.

I broke 2 Philips Sonicare tooth brushes and would like help in fixing them. The problem is the stems have gotten loose and the replacement toothbrush head does not fit tight anymore. Is their a repair person who is familiar with this problem or is there someone who could tell me what to do to fix it myself? Mine have become loose right after the 2 year warranty is over.

If you are familiar with KIWI shoe polish applicator and shine brushes, I have boxes of these birch wood brush blocks that I'd like to use in creating some useful items. These have a small indention on one side that was used for hanging during the lacquering process. I can trim the ends or edges as needed. I've thought of using for shadow box roofs, multiple-sided bowls, etc. but would appreciate any other sensible ideas. Any help is appreciated!!

Recently me and my dad have run across a problem. http://www.100randomtasks.com/_/rsrc/1307405086575/squeaky-clean-boards/Poly%20Clens%20Can.jpg?height=200&width;=200 Apparently our government has banned the use of Poly Clens By Lepage brand here in Ontario Canada as far as I know. Its a favorite brush cleaner for the both of us and we're both surprised when we heard the news not to mention disappointed. We both don't understand why its banned since there are far worse brush cleaning methods that are way more harmful to the environment. So are there any other alternatives that some one could recommend that are similar? And please don't recommend varsol est since these just don't compare and are just nasty. Thanks. :)

I use Gimp for image editing. Recently I noticed that the brush tip is about 20 pixels to the left of the arrow. Now this is inconvenient in several ways, but some of the tools in GImp don't have anything showing the exact point where your selecting, I just have to guess knowing that it's about a half inch left of the point of the arrow. Does anyone know how to fix this? I've looked through the "preferences" and haven't found a thing.
Question by NunchakuMan | last reply
My father and I are currently restoring a metal-working lathe, however, we do not have 3 phase power to power the original 0.5HP 3 phase motor. We do, however, have a slightly smaller 0.25HP motor. At first appearance, it seemed to be a simple AC/DC brushed motor with a field and winding on the armature. There was no wiring diagram supplied with it, but in one configuration (what appeared to be the ameuture and field coils) are wired in parallel for 120V operation. This did not seem right, since the field coils will be simply shorted across the mains, but I assumed that since we are dealing with AC and inductors, this is OK. It works flawlessly, but reversing the polarity of either the fields or armature would cause the motor to sit and buzz. If started manually, it took off slowly but sounded awful. I need the motor to rotate in both directions and do not have enough materials to do this mechanically. On closer inspection after dismantling the motor, it appears there are 4 brushes, connected together in 2 pairs. They are not directly connected to anything. The 4 wires coming out seem to be just for wiring both field coils in either series of parallel for 110V and 220V operation respectfully. Perhaps even more strange, the 4 brushes are mounted on a centripetal switch, which disengage the brushes from the armature. I was able to make out on the rust that it said "revolution induction motor." So I reasoned out that after the fields are energized, it will induce an electrical current in a few of the coils on the armature, and the energy would flow to the other 2 sets of brushes, causing a different set of coils on the amature to energize and this would initially start the motor. After it gets going, the switch disconnects all the brushes and the motor operates as a simple induction motor. My father used to rebuild motors for a small company, and this is in fact one of the motors he repaired. Although he is skilled at this practice, he does not understand the operation of induction motors and can only figure out wiring by strictly following a diagram or trial and error. I am curious about what this type of motor even is, and how it works! In th meantime, I will research induction motors and how they work, and see what I can learn.

I have some plasti-kote enamel brush on paint and I was wondering if it's transparent? I want to paint it on some bottles, but I want it to look like stained glass and not a huge block of paint, if that makes sense. I have tried the tinting trick with the mod podge, water and food coloring, but after i baked it, it still peeled off and I need something that will be a little more durable for the project I have in mind. I had these and found them when I was cleaning up my crafting area and though why not try them, but I don't want to waste a bottle since i sort of need all of them for the project I'm working on. Any help on this would be great.
Question by taria | last reply
So I have 2 brand new tilt/trim pump motors and thought about making a set of matching electric longboards since products like Boosted Boards seem to have become fairly popular. I am not too sure whether the tilt/trim motor would be strong enough though, they are a decent size motor though. But it got me thinking what size is required for an electric longboard? The main problem with the tilt/trim pump motors is that I can't find specs on them anywhere, just specs for tilt/trim pump assemblies they are off of, but nothing about the motor itself other then SAE J1171 Marine rating. Because of this I thought of buying another DC motor to do the job. (Picture of tilt/trim motor) The constraints for me is that I have a couple 12 - 24v 100A motor controllers already, for brushed motors only. As well, I want to just pick up a couple cheap $40 12v, 24AH Sealed led-acid (SLA) batteries from the local Ace Hardware and run either a 12v or 24v motor. Options on eBay for affordability purposes range from 12v, 24v, 90v and 180v dc, obviously 90v and 180v are out of the question. Looking through the 12vdc and 24vdc motors, there are many fractional HP motors available. I was looking at something like this; http://www.ebay.com/itm/172252712203?_trksid=p2055119.m1438.l2649&ssPageName;=STRK%3AMEBIDX%3AIT Running 1/4 HP at 24v, would 1/4HP be enough though? I know electric motors HP ratings are lower then petrol engines, a 6.5HP petrol go kart runs about the same as an identical kart with a 1HP electric motor. If that isn't enough I am thinking a 2/3HP motor from Holley might be better? http://www.ebay.com/itm/361524972024?_trksid=p2055119.m1438.l2649&ssPageName;=STRK%3AMEBIDX%3AIT Wondering if someone has an idea for sizing. I know lots of eBikes and Chinese electric mini bikes and things have 500W motors, so roughly 2/3HP, so I can't imagine I need more then that. As well I don't want it to go too fast (fear of speed wobbles) but if anyone would have an idea of sizing that would be super helpful!

OK, so I recently bought an airbrush set for $20 at a garage sale. I don't have an air compressor, so I bought the canned proppelant stuff and the nozzle attachment I need, for another $20. Then, I noticed there wasn't a hose in the kit, so I spent about 12 more bucks. I would love to try it out, but I don't have airbrush paint, and I am reluctant to spend any more money on this project. I do, however, have some standard Testors model paint laying around my workbench. Will this work in my airbrush or will it clog it up or damage it in any way?Thanks,Noahh

I know you need to increase the power going into the motor. I don't understand exactly how? I know that a different battery with higher voltage output should work, but is there any other way? If so, how and what would I need? I trust that you guys can come up with something. P.S I am aware of the potential danger of the motor if I increase too much.

Hi gang, My wife used her mixer to make two pounds of dough for years, but recently the motor would struggle and eventually stop. The only way to use the mixer now is to make smaller batches of dough. I took a look under the hood, and all seems OK. The brushes on the motor are clean and making good contact, the cooling fan moves air over the motor as it should, all the gears were well lubricated and moved freely, nothing was broken. What made the motor lose it's mojo? Is there a way for me to make it strong again?

I have a few motors (2) that i would need to be able to drive via a PWM input (Probably from pi/arduino). I have been looking at H bridges, and that seems to be my answer, however, I can't figure out which one i need... The motors are identical 9v ~2 amp stall current motors. I would need both directions for each, and would obviously be using an external power supply. With that said, which H bridge would suite my needs, along with what type of setup? I only have abut 4-6 PWM pins left to use, if that helps.

Question by SatishW | last reply
I bought a small brush-less motor that was designed as a motor for a small RC plane. I tested it by spinning it with a drill. I was surprised to find that the motor did not generate much in the way of voltage. Why not? It's too bad - many small brush-less motors are so nice. No brushes, ball bearings, and low cost. I would have thought that forcing a brush-less motor to spin would have generated power. Thanks for any insight.

I am restoring the wood trim in the hallway of our 1850 greek revival plantation manor. The baseboards, door frames and doors have been stripped with a heat gun and there are areas where the original brushed on (painted?) grain sample is visible. I want to reproduce the look. I tried using glase and paint and did the riser baseboard on the stair case. I used a comb and it just doesnt have the right look. I m worried that when i get to the intricate door frame which is approximately 6" wide, that the comb will be too difficult to give the right look. I need to have advice on type of paint/varnish/stain to use and what kind of brush to give me the right look. I would contact a professional, but there is nobody around here that knows what I am talking about.

Hey everyone.... :) I'm organising a camp to encourage high school students to take up STEM courses..... and I'd like to have them build their own RC quadcopters. I want the course to have a minimal fee.... so the quad should be INSANELY CHEAP. The quad should be able to do just one thing:FLY. Also, durability is not an issue.... just one or two flights should be sufficient. 1)Can someone please suggest a design using brushed instead of brushless motors? (Simply because they're cheaper) 2)If there's any way I can build a flight controller using off-the-shelf components.... please share your ideas.. 3)I have no idea about how to make the remote control/ RF transmitter....... is it the same as that of an RC toy car remote control? 4)I've come across some lovely designs where the frame is made out of paper or cardboard.... so that's not an issue.
