We are looking for an Injection Molding designer to design a case for our PCB. We have an example of what we would like the case to look like. You will need to take into consideration the smooth design and aesthetically pleasing aspects that we are looking for. However the goal is to have the design easily manufactured from an injection molding tool. So the Overall focus of the design is to reduce the amount of elements needed to create the tool that will ultimately produce plastic parts the make up the overall case. So we are only looking for experts with previous experience with prototype of injection molding

Hi, I need you to source a company that can build me a custom LED to meet the exact spec below. I cannot accept anything different from the below specs so please do not ask if something similar will work. I am looking to buy 500 - 1000 that meet the below specs for prototyping in July and then 250 000 - 300 000 for our first 1000 unit production run in Sept. of our new product line. This SMD LED is not available as an off shelf product product so you will need to find a company who can build one to meet these specs. If you have no experience in sourcing or SMDs or LEDs do not apply for this job as you will be wasting your time and mine. Target Price Per Piece in USD - $0.05 SPECS a. 5mW Output b. 680nm +/- 5 bandwidth c. undiffused beam and uncollimated d. Continuous wave e. Less than 1 degree Temperature Change during 20 minute continuous operation f. No coverings over laser - EX: Lens Cap g. 2.1V, 8mA input Thank you, Mitchell

Short description: In this system, each table in the restaurant gets a battery powered wireless calling device with buttons. When pressed, this calling device sends a wireless zigbee or generic 2.4GHz message that will be received by one or more of the base stations of the system, which are based on Raspberry PI A+. The master base station memorizes the call status for each transmitter so that said information can later be polled over wifi and displayed by apps run in smartphones worn by the waiters. The apps for said smartphones are developed in a separate project ? you don't have to develop them. Deliverables for this project: ? For the calling device; scematics, PCB layout, MCU firmware ? For the Raspberry base station; software (including installer script that makes the software start upon boot) All software must be delivered with source code, and all source code must be professionally written and well documented in English. Suggested milestones (open to discussion before proje...

We are currently working on a PCB with a 3G module, ARM processor, DC/DC and some other parts. From time to time the 3G module or uC stop responding - the 3G module usually burns up and some of the pins of the uC burn as well. Although we have a great engineer working on the project, we'd like to have a fresh look from an experienced engineer that may think of something we've missed. We will of course give more information, the schematics are in Altium.
