Desktop Factory: Our Product Grid Beam is a do it yourself wood and metal building and construction system. Chispito How to Wind power is abundant, clean, inexpensive and easy to do. It is our belief that anyone can be in control of where his or her electricity comes from. There is nothing more rewarding and empowering than making a wind powered generator from scrap materials. Safety should be our highest priority. Materials This manual is based on using a 260 VDC, 5 A continuous duty Treadmill Motor with a 6 inch threaded hub. You may use any other simple permanent magnet DC motor that returns at least 1 V for every 25 rpm and can handle upwards of 10 amps.

Natural Pools or Swimming Ponds Natural Pools or Natural Swimming Ponds (NSPs) Let nature clean the water... Chemical-free water garden and swimming pool. The plant portion, or regeneration zone, is separated from the swimming area by the wall seen a few inches below the water’s surface. www.naturalswimmingpools.com The pools have skimmers and pumps that circulate the water through the regeneration zone and back into the swimming area. The aquatic plants filter out contaminants and use nutrients from the water as food which helps prevent algae. There are many options as to design. A gradual slope contains the plants, gravel and loamy sand, a wall keeps them separate from the swimming area. Vacuum but twice a year and tend to the plants as needed. The regeneration zone can be along the perimeter of a natural pool or a pond unto itself but connected to the swimming area. www.gartenart.co.uk Plants steel the nutrients away from algae. www.gartenart.co.uk Half regeneration area, half swimming pool. www.living-pool.eu Builders:

The Most Incredible 3-D Printed Things We’ve Ever Seen ⚙ Co The levees have broken for 3-D printing, and the resulting deluge of printing-concepts-on-the-cheap is flowing faster than we can gather. The best of these rise to the surface for their innovating predictions of a faster/safer/healthier future. A Robotic Hand That Doesn’t Cost An Arm And A Leg Teen engineer Easton LaChappelle created his first robotic hand out of Legos, fishing wire, and surgical tubing--a feat that earned him 3rd place at the Colorado Science Fair. Speaking at TEDxMileHigh last month, LaChappelle presented the arm, which features as much motion and almost as much strength as a human arm and costs just $400.

Piece de telephone: ecran lcd samsung ,Htc, Sony, Motorola, vitre tactile - Piece-mobile Batteries - Learn The battery pack is one of the defining aspects of any PEV project; by and large it determines the weight, range, and cost of the vehicle. For these reasons a solid understanding of the various battery types is more than a little useful. General Battery Types While there are a lot of chemical combinations that can and have been made into useful batteries, in practice there are only four rechargeable types readily available in sizes suitable for ebikes. For a long time, lead acid has been the defacto standard for EV's. Nickel Cadmium was the old standard for rechargeable consumer cells in the familiar AA, C, 9V series. Nickel Metal Hydride is quite similar to Nickel Cadmium, but with a higher energy density and a safer environmental record when disposed of in landfills. Almost all consumer electronics that have a plug-in charger these days are powered with lithium batteries because they can store about 3 times more energy than NiMH.

MAKE HOMEMADE SCIENCE TOYS AND PROJECTS Alternative Print Surface | Solidoodle Tips I’ve always had trouble with ripping my Kapton tape. Prints are can be removed easily, without damaging the tape if the print bed cools down, but it takes so long to heat up, I hate to let it cool too much. Also, if I want to cancel a print and restart it right away with tweaked settings, I’m too impatient to cool it down first. The solution is to forget the Kapton altogether. The great thing about using glass, is that when the print is done I can take the glass off and let it cool on the table without needing to turn off the heat. The problem with covering the aluminum with glass is that you can’t get to the leveling screws. Like this: Like Loading...

AutoSpeed - DIY Digital Anemometer If you are a sailor, fly a kite or model aeroplane, or just like knowing the weather around you, this anemometer project is for you. The design would also be very useful in the geography or science departments of a school. For those who don’t know, an anemometer is simply a device that measures wind speed. The Design The design uses a cup-type spinning assembly that is rotated by the wind. While that’s the electronics out of the way in one fell swoop, the mechanical design is very important if the anemometer is to be both durable and reliable. Sounds expensive and difficult to source? Building It The first step is to select the bicycle hub. When picking a hub make sure that the axle is able to spin freely but without end-float. Either way, make sure also that you get the nuts that go on the axle. Next, you need to cut out the plastic rotating arm assembly. The plastic material “works” beautifully and can be cut with an electric jigsaw or even a coping saw. Calibration Final Setting Up

How to Make a Mini Fog Maker Video Kipkay Videos Male Speaker: I get lots of request to mixed up. So here is one of them to make this fun and easy Mini Fog Maker you'll need a coffee can remove the label, it will look a lot cooler. Then I dug through my box of computer fans and found a nice 2.5 inch square one. Lay it on the plastic top that came off the coffee can and then we going to make a mark around it and cut that squire out just inside the mark you made. Apply some hot glue or other epoxy around the edge of the hole and then attach the fan. I found a section of pull hoses, which will be great for this project because it has a nice nozzle at one end and that's going to be matter at the very top of our can. More kipkaySmokin' videos!

Thumbscrew to level bed from beneath (Page 1) — STL Sharing & Print Showoff — SoliForum - 3D Printing Community Trying to see a gap of 0.010 under a straight edge is not easy. When I put the straight edge from near left to far left, I can put a piece of paper under the straight edge and move it almost completely from front to back, so there are "lips" on the front and back edge. That is the only thing that I can detect using your suggestion. In particular, I cannot detect the 0.010 problems across the back. I bumped my bed temperature up from 85 to 95, and that has allowed me to get larger pieces to stick, although I believe that I am relying on the adhesion on the front, along with the structural integrity of the piece, to keep everything in place. I'm not sure what the spec is here.
