I need to have an MCPCB designed for a high power LED. There are plenty of off-the-shelf MCPCBs available, however these are all too large for our application. The circuit is quite simple. It is a cathode-ground high power LED. The attached PDF lists the specs for the LED landing pads, and shows a possible design. The footprint listed is 13.5x6.5x2.5mm (LxWxH). The width (W) of 6.5mm and the total height (H) of the MCPCB of 2.5mm is required, however the length (L) of 13.5mm is flexible if you think it needs to be longer or if there is a more ideal placement. To have this made, the Fab. needs at minimum a schematic and .dxf. Gerber files are also needed. To Summarize: Looking for someone to design a very simple LED circuit and MCPCB layout. -Must have experience designing MCPCBs for LEDs (both circuit and layout design). -Must deliver schematic, .dxf, gerber files and all other documents required for fab. -Small footprint, approximately 6.5mmX13.5mmX2.5mm Metal Core PCB Current...

You will get a real life netlist of a combinational block (no memory elements). Your task, is using standard Python programming language Generate a new logically equivalent netlist which only uses NAND2 and NOR2 gates, which replace all the different gates that are there already.(refer block32 notepad for verilog code) Requirements: ? Code should be tidy and commented ? The code should work also on other netlists ? make it as generic as possible ? The netlist generated should be a legal verilog netlist including input, output declarations, wires, unique gate names etc. ? Tip: use a text editor that supports highlighted verilog syntax like: sublime text, Notepad++, Nedit or emacs ? Assume the drive strength to be X1 in all NOR2 an d NAND2 that you would use ? Code should be easily extended to new types of gates upon request ? i.e. when a new netlist comes with new gate types inside ? the change process should be easy

Hi, I'm looking for a US based EE to design and prototype and simple circuit with a 4 digit 7 segment LCD display, a hall-effect sensor, and a pushbutton. The circuit should have a footprint no larger than 90mm x 45mm x 12mm The basic operation is that clicking the button increments the count while the state of the hall effect sensor determines how the count is incremented. There is more detail than that, but those are the basics. Please quote both the development cost and ballpark cost and lead time for making 20 units. Final deliverables need to include layout files for production as well as all firmware.

I need a circuit drawn. The end result will operate like a solar powered lawn light. It will be scaled up. I already have some solar cells and hopefully they will work. Each unit can hold up to 8 solar cells. They are 3" x 6" - 1.8W each. The cells can be used to turn the circuit on at night by using the circuitry. I have a battery but unsure whether it will work. Super rechargeable Li-ion battery - model DC12400 input 12.6VDC output 12.6-10.8VDC 4000mAh (these batteries came from China and are difficult to get a hold of. If we can source a suitable replacement in the US that would be preferable) The battery would need a charge controller built on the board as well. all this is to power some LED strip lights. I purchased some that may be a little too expensive for the application. They are SUPERNIGHT 5M Waterproof 5050 SMD 300 Epoxy LED strip light white. It is 16' long but can be clipped to smaller sections. I know how to solder so that's not an issue. These are waterproof ...

We are looking for consultant that can help us do some fairly basic electronic design work. We have budget for this project and are ready to start immediately. Essentially we want to take an existing reference design for WiFi enabled smart plug (   [obscured]  /tool/TIDC-SMARTPLUG-WIFI ) and perform the following modifications: 1) We would like to have two (2) completely independently controlled and monitored egress power ports. Per the documentation, the relay, meterology and microcontroller per egress port is "scalable" so this looks to be a fairly simple task. We would ask for help both with the hardware design as well as the software modifications to be able to control/monitor the second port similar to the primary (note: I am linux software engineer with 20 years of experience, but I have never written hardware drivers). 2) We need to add an electronic or mechanical switch: the board will be housed in a lockable chassis, I just need some notification when the ch...

Component CN2, U2, L1, CN3, U7, IR1 and IR2 need footprint made or adjusted for sure. Check ALL others to DigiKey part numbers and confirm. 3. PCB outline is created. It is 43MM round. It is 4 layers. Some components have required placement. After you confirm above, send files back. I will place a few components and lock. These can not move. After you place remaining components. 4. All test points (TP) need to be round pad 40x40mil and placed all on one side of PCB. These are used to load firmware during manufacturing. 5. Send PCB to me after placement. I will verify before route. 6. Route. Follow standard PCB rules. Minimum trace width is 10mm. Can be 8mm but only if need. Power traces should be bigger. GND and Power pours where needed. 9.
