Hi Miguel, I am a fire sprinkler contractor in the Los Angeles area in need of the design, plans, and possible stamped approval of a new 4" inch fire line water service. For a new fire sprinklers system in an existing bldg. In Tustin CA. We are trying to find out if we can connect to the (what I believe is) 10" inch city main. I have a set of approved fire sprinkler underground piping ready upon request.

I am looking for someone with experience with HDI PCB layout to assist me with the layout of a hand-held ultrasound medical device I am developing. I am an electrical engineer who became a physician and have created a startup company to create an ultrasound product. I have a lot of experience with altium and have created the schematic for the design, but I need an expert to help with the layout of this complex board. The board will be an HDI 12+ layer board with multiple 0.8mm BGAs to fanout in a 45 mm x 90 mm space. I am looking for someone to held guide me on via choices (microvia, blind, buried, through hole), BGA fanout strategy, controlled impedances, etc.

Development of pulsed power device for life science application. Will need to sign an NDA. Software, firmware, protoyping.

We are seeking a qualified electrician to perform a thorough safety inspection of our mobile surveillance unit. The unit is trailer-mounted and solar powered. It is a 24V system and utilizes a variety of networking equipment such as POE injectors, switches, and security cameras. Your primary responsibility will be to assess the electrical systems and ensure compliance with safety standards. This includes examining the wiring, circuit breakers, grounding, and overall electrical infrastructure. As a qualified electrician, you should possess a deep understanding of electrical safety protocols and be able to identify potential hazards or deficiencies. Strong attention to detail and meticulousness are essential in this role. Skills required: - Low Voltage Electrical safety inspection - Wiring evaluation - Circuit breaker assessment - Grounding analysis - Knowledge of safety standards This is a small project that can be completed in under 2 hours. We are looking for an intermediate-level electrician with experience in solar systems.

Seeking a highly experienced professional with expertise in working with and selecting optimal small electric gearbox motors (high torque) for new products. The ideal candidate will have a deep understanding of small, high-torque, low-RPM motors and gearboxes, as well as experience in product design and development. This is a short consultation 2-3 hours total. We just need to identify the best candidate motors given our requirements. Motor OD should be 16mm, and length including gearbox not more than 29mm (with typical 4mm D shaft, 10mm length). Need rated torque at least 3.5 kg.cm, and a much higher stall torque.. We've had a lot of problems sourcing such motors on Alibaba which break very easily when they stall (such as the GM16-1629). Please be very familiar with with leading motor manufacturers such as Faulhaber, Maxon, and Portescap, and an expert at all the related stats about motors as well as motor control and protection circuits (stall protection ). We're still undecided whether to go with brushed or brushless BLDC. Would like to do a zoom call and explain the details. Thanks

Hello, I'm looking for a generalist mechatronics engineer (mechanical, electrical) with skills in 3D modeling, 3D printing, Arduino circuits, programming, etc. based out of the greater Los Angeles, CA area to assist me with various engineering tasks. The clients I work for have a variety of project types, and so the project assigned to the contractor will be dependent on his/her particular skill set. I'm an engineer myself, so the work assigned to the contractor wouldn't be anything that I can't handle myself, but the volume of work from my clients has increased, so I'm looking for a contractor to help take on some of the workload for me. Kindly submit your proposals with a list of prior experience related to the following (not all skills need to be present, but including examples would be very helpful): - Arduino - CAD modeling (Solidworks, Fusion 360) - Prototyping - 3D printing - Circuit design (KiCAD) - Programming (C++, Python)

Prefer you are based in the San Francisco Bay Area to meet up in person. Building a new massager device, and need the help of a hands-on mechatronics expert to help build prototypes of the device. I've already built multiple 3D printed prototypes, but need help taking it to the next level of refinement and function. Prefer extensive experience in the following areas: 1) Micro gearbox motors, understanding torque requirements and protection circuits for such motors and working with such motors 2) PCB/Firmeware design 3) Strong mechanical engineering background as much tweaking is needed here in building the prototypes 4) 3D printer available (I have a bambulab Carbon AMS printer I've been using thus far in the prototyping). Most Important preference is that you're based in the San Francisco Bay Area. I'm hoping to meet up and discuss in person and periodically meet up as the project progresses.
