Prototyping Jobs

I need several flat parts cut from license plates that I will provide no thicker than ¹∕₄" (≈6 mm). Clean, basic cuts are perfectly adequate; I’ll grind and finish later. A CrossFire CNC setup—plasma or laser—will suit the DXF or PDF files I’ll provide. I am curious how these perform on this phase and then we can do more. Here is how I see the job flowing: • You receive the DXFs or PDF, nest them as you like, and run the program. I mail you the plates for testing (Aluminum and Steel). • Light deburring after the cut keeps edges safe for handling. I’m ready to send files immediately and would appreciate a 48-hour window from file hand-off to shipment.

I’m working on a new umbrella intended for everyday personal use and need a product developer who can guide it from early concept to prototype-ready design.

This task is for generating a KiCad v10.0 schematic from a given PDF. And if someone wants to also generate the pcb layout for it is welcome but the budget is very tight. There is an unfinished KiCad project that has the parts in schematic though the schematic has no connections, just the parts, also their footprints are/do exist in a pcb layout but without traces connecting them. I would like to have also the complete pcb layout generated but I want to keep the cost for now really low so I can accept just the schematic work. If someone though wants to bid for both schematic and layout then I could consider if the bid suits my budget. Please specify in your bid if it is for schematic only or for layout too. The schematic has FPGA/ADC/DAC/CODEC/CLOCK/POWER/etc spread in 12 pages, whoever w...
