Inspired by the historical visual progression of mainboards, we are looking for an innovative design to use as the back of a large shelving unit. We are looking for a design to go in a display case. The display case will then be used as a holder for glass shelves. Think of it almost like a glass bookshelf. Except, instead of the back being a cheap piece of board held on with tack nails like a shelf from IKEA, the back will be the design you come up with. Dimensions: 8ft wide 3ft high 1-3in deep The case is being used to display tech items. So we would like the design to reflect technology. Think mother board but on our scale. The original thought was to collect old motherboards, including ram and cpus. We were then going to lay them out on a 8x3 piece of plywood and glue them. Instead of this, we now want to get a design that a CNC machine can make. Material used: Wood and old metal. The design should induce a feeling of technological progression. So from left to right the design should transition from old circuit board tech, to current tech, to possible future tech (this part is open for interpretation) As an example, in the attached picture, the green part is what we want to replace with our 3D circuit board idea. Please note that the picture is just one from google and does not represent the actual shelf we are building The entire shelf will sit on top of a table, meaning that it will be at eye level for the average person.

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

I have a 3d model of an upright that was produced using topology optimisation software. The optimised model provided must be used as a guide to create a parametric CAD model. The optimised solution will be provided as a solid works file and I will require the finished CAD model as a SolidWorks file. I will also provide the original upright design so that you can use it as a reference when creating the new design I will need the job done by the 15th of october

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.

Off/On Road Super SUV, 3 seater Central driving position like a Mclaren. Rear engined, removable roof which when not in use goes over engine bay. 26 inch rims. Very clean lines. Will use donor lights (pictures included in files). Car must be dramatic with very clean simple lines. Interior must be very simple and clean lines. I have uploaded many files for inspiration. Countach for rear. Corvette for door treatment. White lotus for air vents. Diablo for roof and body lines.
