    How would I get this Custom Cable Manufactured for a Prototype?

    I need to have a cable manufactured for a prototype that I am working on and I'm at a loss as to where to go to have something like this made. I've contacted a few places that specialize in custom cable manufacturing but they all have 500ft+ minimum lengths and I only need about 20 feet made...

    Tapping into Power from Wall Outlet Receptacle?

    Thanks Lionel for your thorough response. I suspect you are right in that many homeowners are not going to want to fuss with wiring an outlet but I do believe that my product will be worth it to many. As for the wire tails out of the back attaching to the existing screw terminals; can I contact...

    Tapping into Power from Wall Outlet Receptacle?

    Hi GroovyGuy, I think you misunderstood. I am absolutely going to seek UL/CSA approval for my active face plate product. It will be inputing 120VAC and outputting 5VDC and will therefore we classified as a power adapter. What I don't want to do is have to provide the actual outlet receptacle...

    Tapping into Power from Wall Outlet Receptacle?

    The active portion of the face plate is part of my invention that I'm currently filing a provisional patent on. I can disclose more later. For now I just need a good way to tap into to power without violating any code requirements.

    Tapping into Power from Wall Outlet Receptacle?

    The reason that I do not want to have to use the receptacle for the connection is because I want to keep it very minimal and slim. By blocking off the receptacle, the product would be very thick.

    Tapping into Power from Wall Outlet Receptacle?

    Thanks Groovy Guy for the response. I'm really trying to avoid having to provide the actual wall receptacle because this increases complexity. My product will be an active face plate with a step down transformer and will therefore require UL approval on it's own. What if I used the setup shown...

    Tapping into Power from Wall Outlet Receptacle?

    To clarify I would want to be using a forked terminal not a ring terminal so that it can slide under the existing screw terminal that holds the live and neutral wires. Does this configuration violate code? I am not interested in hearing about the usefulness of the product just whether or not my...

    Tapping into Power from Wall Outlet Receptacle?

    Hello All, I am working on a product that will be an actively powered face plate for a wall outlet receptacle. Basically the socket will provide power for my faceplate and I need to tap into the power of the outlet. There is a company that makes an active face plate () and they use a patented...

    What is the bonding mechanism in Soldering and Brazing?

    I think this is a pretty basic question but I'm curious about the type of bond that is formed in soldering and brazing processes. Take a tin/lead solder onto copper for example; does a metallurgical bond form between the tin/lead solder alloy and the copper even though the copper is not melted...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Thanks for the imput CompositePro. So basically what you're implying is that the molten extruded aluminum will not fuse to the solid substrate because the molten aluminum will instantly solidify before bonding. I have come across someone who was able to successfully extrude molten solder and...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Well can't this thought experiment be answered with soldering and/or brazing? Solder uses flux to remove the oxide layer on the surface of the solid as well as the molten liquid. Without this, the solder will just ball up and not bond because of the oxide barrier. Once flux is applied, the...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Ornerynorsk that is a very valid point about the surface tension of molten aluminum. So I suppose that raises a more general question: In a high vacuum will liquid aluminum fuse to solid aluminum under the weight of gravity alone, or will it just solidify as a solid ball on the surface. In...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Thank you for the idea Berkshire. The problem with the HF tracer is that I won't be using an electrical arc since I do not wan't to melt the base material that is fusing to the molten aluminum exiting the nozzle. In addition, the HF will disrupt my motion control electronics. The laser ablation...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Thank you Berkshire. I will definitely check out these alloys of solder for our prototype. Having a solder with a much wider plastic range will help our project immensely. Another challenge that I cannot seem to figure out has to do with aluminum side of things. I know that aluminum rapidly...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    I'm thinking about developing a prototype extrusion nozzle using solder to prove the concept at a much lower temperature. Can anyone recommend a commercially available alloy of solder that has a larger temperature range between the solidus and liquidus? I'm shooting for at least 60% solid at the...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Thanks for the information. I am very curious about the A356 hypoeutectic alloy, it sounds like it might help my issue. Has anyone worked with this alloy before? I'm curious about the fluidity of this alloy when it is just barely melted (right above the solidus temperature). How does the...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Hi CoryPad thank you for the response. Regarding semi-solid casting, how viscous would the material be in the liquid phase? In other words, if it were to be extruded as a liquid (assume 50% in the solid phase) through a 0.015" diameter nozzle onto a base plate of aluminum, would it instantly...

    Aluminum Alloy with a Pliable Transition Zone Between Solid and Liquid?

    Hi All, I'm working on a project where our goal is to design an extrusion head for aluminum wire. Basically the goal is to feed 0.035" wire through a tapered ceramic nozzle that is wound in a water cooled copper induction coil so that when it exits the nozzle (tip diameter 0.015") it will be...

    Alternate method to determine position in two axis besides using linear encoders?

    Hello, I'm working on a project where I will need to determine and record the XY position of a stylus over an 18" x 36" table. The stylus will be mounted on a gantry to move freely in the Y axis, and will also be mounted on a slide on the gantry beam to move freely in the X axis. I want the...

    Calculating Transformer Core Area

    Hello, My application requires the use of a custom transformer and I want to calculate the theoretical minimum core cross sectional area that will be needed in order to achieve my power output ratings. The input voltage will be standard 120VAC and the output will be 5VAC at 500mA. I would like...
