    Sleep Apnea Monitor I have developed a mask/monitor, using an Arduino Uno. When I'm sleeping and I stop breathing, a buzzer alerts me to start breathing again. Due to power requirements and the weight of the Arduino, only the wind sensor and buzzer are mounted on the mask. These are connected by five-foot wires to the Arduino, which in turn is connected to a 110-volt outlet. The goal of this project is to eliminate the wires and create a wearable mask with all components on the mask. This means reducing the weight, powering it with a rechargeable battery and transferring data wirelessly. The Current Approach I have a wind -sensor mounted on a mask. When the user stops breathing, the number of minutes they've been breathing properly, when they stopped, and how long they st...

    We require a PCB designer to layout a PCB for us. The test circuit has been developed on an STM32 Nucleo-144 MCU Development Board, NUCLEO-F767ZI. You will be required to draw the full circuit based on the development board and then after approval, layout the PCB in accordance with the circuit diagram. PLEASE READ THE ATTACHED DOCUMENT. IF YOU DON'T READ I WILL DELETE YOUR BID.

    I have a small vertical garden supplied with water from a 40 l container (upper left, in video) run through a set of gardena hoses. It's currently turned on and off manually. However, I would like that to programmable for when on vacation. The problem, however is that the gravity-pressure from the container is not large enough to push through most of-the-shelf systems, I think, probably because they are these tight electromagnetic valves. I therefore want to buy a solution that can overcome this. I call it an Arduino-controlled ball-valve because I think that would be a neat solution, but really anything you suggest that convincingly sounds like it would work is something I'm interested.

    Only a hardware development is required. No code. Time for project development: max 6 days. Sensor used for input: piezoelectric Microcontroller used to receive the amplified sound: ESP32. Output voltage range: 0-3.3V. Midpoint Bias near V=1.65V (half of 3.3V) Operational Amplifier model will be defined before start the project. We have some circuits tested but with problems as clipping and sensitivity signal. Signal amplification should be the higer possible. In oder to avoid the noise, a 10-15Hz filter can be used. We can cut any input or output signal above a specific voltage threshold Battery used: 1x3.7V (voltage used as input for sensor = 3.3V) Software to use: KiCad for schematic and any other software for simulate it (for example LTspice). Project files will be provided....

    Hi, We need a compacthigh-quality Qi Wireless charging receiver for our project. Currently, we are using the following cheap version, but can not trust it for a long term project. We are interested to build one based on Western Chips (eg: TI, ST .....) with good documentation and test data. Your responsibilities: 1. Find the best chip for the purpose 2. Designing the boardcoil.... 3. Assist us with finding the PCB manufacturer who can provide all components and ship the final product. (We do not want a design that could NOT be manufactured) The design is very straight forward and could be based on the best practices and example circuit provided in the chip's data sheet. The only matter to note is: in our product 2x Qi receiver modules will be used. The output of these are di...

    Please see the chat and amplifier that you quoted on. The understanding is that you complete the rask for a fixed price although you asked that a hour rate project is to be made. We both agree that when the design is done that the fee of 450 is to be paid for the task, irrespective of the time spent to complete the task. My engineer will review the schematics and consult if he sees any possible problem on the design. Then you can complete the pcb. Please take care of the component that is to ne used as not to become obsolete.
