Hi People, I would like to obtain a quote to design and produce a 220-240VAC 50Hz to 115V AC 60Hz Pure Sine Wave Converter to suit a 15 watt electric motor. The device needs to withstand a Start current of 7 x FLC and have a duty cycle of 20 minutes on/10 minutes off. The device needs to plug into an Australian Power outlet via a flex lead and be equipped with a US plug to accept a US product plug. I would need the design, initially as a prototype in a test box. The design must then be able to go into production in a compact Moulded Plastic case. The case can be an "Off the Shelf" box if it looks professional. The design will need to meet all Australian and NZ standards including AU/NZ Approvals (RCM Electrical safety Mark, A-Tick, C-Tick, MEPS

This project requires a person with experience in architecture and/or interior design of retail store located in Mexico. This is the first store and will be a test. If it is successful I would like to use this design theme to be followed by future stores. The location is small, estimated 5 meters X 6 meters and since this is a small test business we are working with a extremely small budget. A modern, minimalist, clean and technology feeling is important. In this small space I need assistance creating the following: 1. A small division for a workshop where staff will perform cellphone repairs. 2. Shelf displays: Displays to feature your products such as cellphone cases and refurbished (used) cell phones). It is a small space so we need to be careful not to clutter the products or space. Capitalize and make good use of spaces at the end of shelves. Place your popular or targeted products between eye level and knee level. 3. Window Display: There is not enough floor space t...

Re-implement Legacy Z80+Peripherals in a Xilinx FPGA PCB The project is to re-implement a legacy logic board that uses a Z80 derivative processor (HD64180) and its contemporary peripheral control ICs (see the schematics and BOM files) in Xilinx Spartan-6 FPGA + Static RAM. Requires re-implementing the original LCD controller for a 320x240 monochrome LCD to a 640x480 LCD, using 2x2 pixel replication. The object code for the HD64180 is to be run as-is. Prototype PCB has been fabricated and will be supplied, along with the FPGA, FPGA JTAG cable, LCD panel, and some other components. You will be required to supply some components on the PCB such as the processor, SMD resistors/capacitors and header connectors. You will then solder the components to the PCB, test the basic functionality of the FPGA, and implement the logic in Verilog. The PCB has a PLCC socket for a Z8L180 processor (compatible in default mode to HD64180).

Hi, We are looking for a talented, experienced hardware engineer/designer for our lighting unit. It's a LED lighting unit that uses power cord but we want to make it without cord. So we need to design and make a custom battery power unit is rechargeable. Also, the battery power needs to be thin, needs to fit in ~ 11"x5"x1/2". If you have an experience and know how to make custom battery unit that is rechargeable, please contact us. We prefer local talents but we're open to work with overseas team.

Need to design a high speed counting circuit to detect the time difference between two separate signal pulses with 1nsec resolution. The leading edge of signal 1 pulse should start the count cycle, and the leading edge of signal 2 pulse should terminate the count cycle. Please advise on most appropriate design. I have been envisioning synchronous counters clocked at 1 Ghz with a total of 32 bits, which could pass data through shift register(s) for transfer of data to unknown interface (possibly FPGA). Counting cycle could be enabled with signal from a latching comparator, and disabled by the signal of an additional comparator. Once the count is collected, the cycle is reset for the next set of pulses. I have data sheets of circuit components that may work but am uncertain if they are the most appropriate selections. Deliverable includes selection and refinement of circuit components with associated BOM, generated circuit schematics, and associated PCB layout files. Phase 1 - Select...

How i imagine this: An button is pressed, then an timer starts to count and sand pours after 5 seconds water is poured for 3seconds( still with timer) after water timer the cement timer starts and pours cement after cement everything is mixed for x minutes and dropped. Would need an fbd which would have into its design the ideeas wrote above I need this done fast fast. I would select an candidate in the following hour and would need the product at 2-3 hours max after acceptance. Thank you, Mike

Creating a small basic activity tracker, with accelerometer, bluetooth, and basic processor. Need to do a 1000 unit run for initial order (need manufacturing and complete assembly). These are the main components I'm using: 1. ADXL350 Accelerometer 2. ATMega328 Embedded processor 3. NORDIC nRF8001 bluetooth module 4. Basic power management chip, lithium ion rechargeable battery via USB connector, and simple buzzer 5. Plastic case 6. Retail packaging (small box, color printed) Need to print this on a small round PCB, and the dimensions of the enclosure should be around 1.25" diameter X 0.25" thick Can be a plastic case but needs to be finished with aluminium or metallic like paint finish. Please provide approximate cost for the complete 1000 units and approximate BOM, landed in U.S. I will provide case design and PCB design. Can be injection molded or another less expensive process if possible. Low cost is important here for the whole thing.

I need a timeline graph(s) showing the historical improvement of imaging sensors with key technical or product milestones as data points on the graph. X-axis is time and y-axis can be some common measure of performance - or multiple measures. Also need a graph showing cost reduction of these sensors over time based on some common metric. Finally, I need to relate the improvement in imaging sensors to improvements in camera resolution. Either a calculation, table or graph can be used for this. If a graph - I would like some predictive element about the future of camera resolution. Basically, I want to see what potential resolutions could be achieved in 5, 10, 20 years from now on a UAV platform with hyperspectral camera weighing less than two pounds at 200 feet. Currently you get about 1 cm resolution. So 3-4 graphs or less if you can combine information legibly.
