hi , need circuit and design for below requirement a) Hardware schematic (circuit) design. b) PCB layout design with production quality PCB. or any other things u feel to make my device work Refer my recuirment as attached i need an device of size 1.5inch x 1.5inch x 0.5inch including battery battery should be USB rechargable an total of 6 devices should be connected with distance of 2 inches for an strap of 1 feet height and widht of strap should be same like bra strap. In the 1 feet i should be able to install 6 devices with 2 inches distance. Purpose of device - Device specification or requirement is as below - 1)The device you design should be small enough to fit in the 2 inches distance within 1 feet strap. 2)The device should create sense/vibrate only for fraction of sec(just like poking needle into skin). 3)Only one device should create senses at a time . 4)every device need to produce an vibration/senses to the skin with below time intervals time interval :2 sec for first 10 mins then 1.5 sec for next 10 mins then 1 sec for next 10 mins and 0.5 sec for next 10 mins. 5)there should be charging facility with atleast 2 hrs backup if fully charged (prefarbaly USB charger is good) Please give the quote for 1 strap to test it . we can work on other issues later . Note: the vibrators or sensors should be of voltage where its acceptable to human conditions and not to produce more volatage and cause damage to human skin . I believe an voltage of say 2v to 5volts is good

NOTE: WE ARE ONLY LOOKING FOR FREELANCERS IN THE SAN FRANCISCO BAY AREA. The full description for the job can be found in the attached PDF. Note that the budget posted here and the quote we are looking for is for having our current needs met. Those needs are to: incorporate control of pneumatic control valves into our current electronics box which is composed of a couple adafruit and sparkfun breakout boards with an Arduino; find and incorporate a way to sense the orientation of our device; and modify code so that we have better filtering of speed data coming from the truck, a stall feature that is suitable for the pneumatics system, and better user interface. To get a better idea of what we are doing, check out our website: www.xstreamtrucking.com

The overall goal is to create a safe hand-held system at minimal cost, having enough energy stored to heat a nichrome coil of about 0.9Ω for it to be red hot, for bursts of 10 seconds, around 50 times. Deliverables: Provide a functional unit, as well as a BOM, and schematics. The device is a battery powered heating coil The specifications: • The load circuit has a low impedance, of about 0.8 to 1.3 Ω, it is a small nichrome heating coil • Open circuit voltage output around 12 V/ The voltage output may not be constant due to the low resistance, and will rather have a wide range once connected to a load • Higher than normal power is needed between 10-30W • The battery would provide high currents to reach the required power rating, usually 1- 6A to heat the coil • Rechargeable battery has to be able to withstand low resistance

We're looking for an experienced ARM board designer that has experience from developing a prototype to assisting in production run of quantities in excess of 10,000 units. This posting is for a conversation with someone who has aforementioned skills and experience. We will be talking to more than one contractors from Upwork and the one that we select will get the job of actually designing the product for us. Why we're willing to pay for a conversation: We want to talk to someone who has the skills and experience and can educate us on what we need to know about various stages of embedded System Design and development, timeline, certifications needed and an educated estimate on how much is the final product going to cost in production run of 5,000 to 10,000 units. The ARM board should be capable of running Linux and node.js. Cost is an important consideration for us, so we would like to use components that are reliable, easily available, widely supported, value for money instead of the top of the line. When responding to this post, please include what your hourly rate for this conversation will be and the hourly rate you charge for embedded system development.
