Looking for a mechanical engineer with experience in consumer hard goods. Experience and interest in ergonomics, product development, fastenings, mechanics, prototyping, and/or contemporary minimalist design a plus. You will be working closely with the designer to refine the engineered components and mechanics of the product - in this case, a high-end consumer backpack. Time commitment will be flexible- meetings as needed throughout the prototyping and production process. Ideally in the Greater Toronto Area.

Hello, We need to build a platform that moves up and down that is controlled via Arduino (or similar system) and we need detailed instructions how to do it including code and wiring. Here is how should the setup look like: Platform attached to a thread fixed to stepper motor NEMA17 Stepper motor is controlled by control board (as mentioned - Arduino or similar). System will have 3 main inputs: A - number of motor turns “A” B - number of motor turns “B” C - sound input (microphone) And a few other inputs: D - lower endpoint E - upper endpoint F - ON/OFF switch A and B inputs are switches with a numerical value of how many turns should a motor move. Here can be switches (with 5 positions/values) or an lcd screen with buttons to adjust these values. Only five values for each switch will be used. C input gives a start for motor movement. Once the beep is heard - platform is moved up by the distance A+B. Once a double (or different tone) beep is heard, system moves the platform down by the distance B. After turning the machine ON, platform goes down to the lowest point until the lower endpoint button is reached. After the machine is turned OFF, platform goes up to the highest endpoint button is reached. After the machine hears a triple beep (or a special tone), platform goes up to the highest endpoint button is reached. We need to build such system and need detailed instructions including hardware parts, and software code.

Current Scenario: Please review the simplified block diagram. The Flora BLE is connected to the Flora MCU. The Flora BLE transmits at the rate of 9600 baud but even at this baud rate it drops a lot of values On the receiving side we have an nrf51 dongle that captured the data via COM port in to a file. Our windows application reads this file and processes the data further. Ideally we want to transmit at 115200 without any data loss. Required solution: BT native component selection that can replace the Flora BLE and stream in UART mode at 115200 and USB dongle for the PC than can receive it via USB/COM. Simple connections as shown in the schematic for ease of soldering / connecting. Can be any native BT profile. Should work on 3.7V Li-ion battery

Here is the general story of my Hardware/Software project I have to make a Bluetooth mini microphone to capture heartbeats and send it to App (IOS). App should filter the noise the way we can hear our heartbeats through headphones clearly. My situation 1) I need hardware be shipped to the U.S after test 2) Agreed price is including all costs like components/materials and shipping 3) Agreed price will be paid after finishing the project. (No Upwork payment) 4) I have two months at max Thanks for understanding my situation

Deliverable #1: Hardware prototype for two boards ( board A & board B) - it is acceptable to hand mount modules on prototype board and hand wire connections. Alternatively can create pcb. Board A has 2 modules on it. Board B adds a 3rd module. Each module requires power, antenna & high speed serial connections. Deliverable #2: Qty 15 demo boards: Take board A & B prototypes from Deliverable #1 and design custom PCBs. Then assemble, test and validate in 2 builds: Build 1 - 5 units Build 2 - remaining 10 units

PCB Gerber design for a single board with the following features not greater in size than 2.5"X1.5". Battery and power requirements are not very critical right now but a 500 mAh, 3.7V battery should be able to drive the circuit. Our timeline is 10 days. - 2 low noise analog input channels with 10 bit ADCs sampling at 500 Hz each for typically measuring signal less than 1mV - Both analog channels need to have programmable gain with very low noise amplifier. - 9 DOF accelerometer - Temperature sensor (preferably digital IR). - HW timer circuit for on board analog signal analysis - Integrated BT4.0/WiFi chip for wireless communication to external devices and web E-ink display with touch screen and watch functionality (optional)
