Solder, heat shrink and waterproof your splices in one operation.This is the easiest way to make soldered splice in your wiring. It is our favorite way to extend the wires on stepper motors.
This part combines a low temperature solder ring inside a piece of clear heat shrink tubing. It also has rings of hot melt glue at each end. You strip each wire, insert one from each end and cross the stripped ends inside the solder ring. You then heat the tubing with a heat gun. The solder and glue melts and the tubing shrinks. You get a reliable, insulated, waterproof and soldered connection in one operation.
It is also great when you need to fan out one wire to several wires. This often happens when you have one ground terminal, but four wires coming to it. Place the four wires in one end and one in the other end.
Um Computador por 9 Dólares?
Com ligação Wifi, e gestão de Bateria?
Sim, se só precisarem de computadorizar uma Engenhoca, ou terem um Smartphone ou Tablet feito à vossa medida, porque este liga-se a um Televisor, ou Écran de Smartphone, com Monitor é mais caro.
Next Thing Co. Releases “World’s First” $9 ComputerDavid ScheltemaSnuggly situated in an industrial section of Oakland, CA is Next Thing Co. a team of nine artists and engineers who are pursuing the dream of a lower cost single board computer. Today they’ve unveiled their progress on Kickstarter, offering a $9 development board called Chip.The board is Open Hardware, runs a flavor of Debian Linux, and boasts a 1Ghz R8 ARM processor, 512MB of RAM, and 4GB of eMMC storage. It is more powerful than a Raspberry Pi B+ and equal to the BeagleBone Black in clock speed, RAM, and storage. Differentiating Chip from Beagle is its built-in WiFi, Bluetooth, and the ease in which it can be made portable, thanks to circuitry that handles battery operation.
Ter a vossa própria Fabriqueta na Garagem, passará certamente, mais cedo ou mais tarde, por terem uma Máquina de Injecção de Plástico, para os vossos Projectos.
Pois aqui vai uma que podem fazer em casa, baseado no Ilustre trabalho da casa Gingery:
Make Your Own Injection Molding MachineJohn HannonTried, true, and totally doable. Start cranking out solid thermoplastic parts.Sometimes there’s a tool you want to buy, but you can’t justify the cost. In that case, why not make it? For me, a plastic injection molding machine fell into that category — and it turns out they’re not hard to make.I wanted to make solid plastic parts for some of my amateur science experiments. There are a number of ways to make things out of plastic, each with its advantages and disadvantages. Often just cutting raw material to the desired shape works best. Some plastics can be cast by pouring a liquid resin with hardener into a mold (see “DIY Rotocaster,” Make: Volume 41). Vacuum forming works well for making things out of thin sheets of plastic (see “Kitchen Floor Vacuum Former,” Make: Volume 11). I considered making a 3D printer, but for the few plastic parts I envisioned needing, it wasn’t worth the time and money.Plastic injection molding has been around since thermoplastics were invented. It’s a great way to make many copies of a part quickly, and what I like best is that it’s easy to reuse old plastic objects to make new ones.So I built an injection molder based on the plans in Vincent R. Gingery’s book Secrets of Building a Plastic Injection Molding Machine. David Gingery could be considered a forerunner of the Maker Movement — he and his son Vincent have written a whole series of books on building tools for the machine shop.
