New Workout Leg Extension MachineBlind

A rugged 2-way radio without the bulk. View our current walkies at www.headsetusa.com and our rugged android phones at www.sonimtech.com. We need to design the look of a new 2-way radio to be true military spec yet not bulky with large "bumpers". Our goal is waterproof and able to be "dropped of a building" and not break apart.

We are designing a silicone bracelet that will consist of 14 equal-sized, interconnected sections. 7 of the bracelet sections will hold a small amount of water from each of the world’s 7 seas. The other 7 sections will contain small amounts of soil from the world’s 7 continents. The idea is that wearing a bracelet that contains samples of water and soil from around the world will make people feel more globally connected. The 7 sections that contain soil should be a light shade of brown and the sections that contain water should be a light shade of blue. We are open to each designer’s initial suggestions for specific colors to use and will provide feedback after receiving the initial designs. However, we would like both the brown and blue sections of the bracelet to be opaque (i.e. - non-translucent). Additionally, we would like to see two versions of the bracelet in all initial submissions…one that has the 7 sections of water on one side and the 7 sections of soil on the other side of the bracelet. And in the other version we would like to see alternating sections of soil, water, soil, water, etc. We will eventually have different sizes of the bracelet but for the initial design we can use a “medium” inner-circumference size of 7.5” (19 cm). We are looking to have a 3D CAD rendering for prototyping. We welcome feedback and submissions from designers who can suggest approaches for producing a bracelet like this that will need to have small amounts of water and soil injected into the bracelet sections at some point during or after the initial manufacturing process.

The design requires a clean simple method with minimized parts and manufacturing costs. Product is low volume, 250 to 500 pieces per year. We are interested in minimizing capital tooling costs. Design challenge is to design a keyboard slide platform that sits at a 32.5 degree angle (see attached documents). Keyboard slide needs to easily lock in upward position when not in use, and needs to easily be released and slide downward when in use. The keyboard slide is on a cart platform, so when the cart is being moved around, if it gets bumped, we do not want the keyboard slide to dislodge and slip into the down position.

Project is to design a conveyor system to transfer a range a products into a hydro-cooling bath, and then transfer the product through the bath and out the other end. Attached is a some more notes of the project and images of the products. The contents of the Pails and Bladder is hot Jams and Sources etc. Currently we don't know the thickness of the bladders when fill of the products but we can find this out once we have awarded the project. The attached files are only ideas from our customer, they would prefer to have the maximum time of immersion in the bath. Max floor space available is 8m, so as close to 8m of immersion would be ideal. Someone that has done work with Hydro-cooling bath conveying or works for a company that builds this type of equipment will be a great help. Please let us know if you require more information from us before taking on this project.

I am currently using the following relay in a product: http://www.digikey.com/product-detail/en/te-connectivity-potter-brumfield-relays/RT424024/PB969-ND/1095293 It is a DPDT, non-latching relay rated for 8A switching, and a 24Vdc coil voltage. The problem: The "clicking sound." This is for a home audio application, so we need it to be silent. I am looking for a silent version, using MOSFETS for example, built onto a daughter board (PCB) with the same footprint and pin-out as the relay. Note - I only need SPDT capability (I tie the two poles of the DPDT relay via on the board that the relay is installed onto). One side of the relay coil (pin 1) is always tied to 24V. And the other side is either set to 24V or GND via this chip: http://www.digikey.com/product-search/en?keywords=296-19046-5-ND (which is controlled by a PIC micro) Requirements: - An electrical schematic of the new design - A BOM of all the parts required - Gerbers for the PCB daughter board - Same footprint and pin-out as the RT424024 relay. Note, for this SPDT version, the following pins will be tied together (12 & 22, 11 & 21, 14 & 24). They are already tied together on the PCB that the relay currently is soldered to. - Same 24Vdc "coil voltage" (pin 1 always tied to 24Vdc, and pin 2 is controlled externally to be 24Vdc or GND via the external chip mentioned above). - When the relay is not activated, pins 12 & 22 are connected to pins 11 & 21). When the relay is activated, pins 11 & 21 are connected to pins 14 & 24. - Use high current MOSFETs (the lower the turn on resistance, the better! Should be able to handle > 25 Amps continuously (ideally > 50 Amps continuously). - Must have full protection from ESD / over-voltage on every pin. - There must NOT be 'cross-conduction' of the pins. - Must be very reliable - Must be silent switching - Must be the same footprint and pinout as the relay that it is replacing (Mentioned above). Max. height is > 1 inch (we are only limited by the footprint, not the height). - Layout software can be whatever you want as long as I can get the PCB gerbers to send to my PCB house. - BOM should be in a spreadsheet (excel) - Electrical schematic can be in PDF
