The objective is to design and fabricate one or several circuit board(s) capable of collecting multiple vital signs (ECG, SpO2, Temperature). The design can be a new design or one that is based on an existing reference design if the requirements can be met. If a reference design is used, schematics and demo software/firmware will be provided by the freelancer. The requirements are: - Capable of measuring ECG, pulse oximeter (SpO2), and temperature - Use an embedded 32-bit microprocessor with DSP functionality - Data collection of ECG and SpO2 must be simultaneous or with a low, deterministic latency (<1ms) between ECG/SpO2 samples - Sampling of ECG/SpO2 should occur at a rate higher than 100Hz with a good signal-to-noise ratio - Communication over USB/RS232 to a PC host - Onboard storage for at least 10 seconds of ECG/SpO2 data - Powered by a +5V DC power supply. Preferably a USB port. - A touch or infrared sensor for temperature - Firmware/software program demonstrating the fu...

Hi, I have at a fair a device that is able to talk to centralised Heat&AC systems (like the ones that you find in hotels) and to control remotely temperature etc.. The device is marketed as a power saver due to the fact that uses ultrasonic sensors to detect the presence of people in the room and shuts down heat/AC or reduces it based on the setting chosen. The device is powered and uses power line network and a proprietary protocol to record power saving (the delta between the power reduced since the absence and what it would have used in power if the device was never in place). I would like to produce this device, right now this little device (15cmx10cm) can not be bough, so I would like to create one to propose to hotels etc... Would you be able to help? How would that work? I am a software person and never tried HW/Electronics before, so I am sorry if this might sound a bit foolish, but I can assure the project is serious and I have intention to find the right partner ...

Hello, I wanted to know if you could help me. I'm designing a new product that needs an internal power generation. My research has steered me towards "disc type axial flux generators /motors". See attached sketch idea. Basically I need a test bed to prove theory I have based on the contrasts that are given. I can't fully describe the entire design but part of it needs to generate electricity and output it to a outlet, which kind of mimics a typical low voltage wall outlet performance you would find at a normal house. The initial device constraints was to have a cylinder can design with a max diameter of 3.5 -5 inches, and have the device be very light weight, and requiring very little force to spin the axial flux inside. I have not specified a height yet this is all a idea in testing phase. What I'm requesting is a design or instructions to create a test bed in my shop and so I can build and tested it, the shape and design are critical. This is a generator, I will ...

Dear Elancers, I'm was looking for buying a Honeywell resistor board (Honeywell-221508A) but unfortunately I couldn't find it and it's out of stock in most market areas. So I decided to make it by my self which I think it's not very complicated. It's just an analog card with mosfet. I'm looking for someone who help me for building this resistor board and give me some advice for the board. Please pay attention that I only need your advice and help for this so it's not a hard job. in the attachment you will find the pic of the board. Looking forward to hearing from you, Thanks,

We have customers that will want a shoe shine. They will sit on one of those chairs to have a shoe shine. Each treatment is about 10-15 min. There will also be a camera on top of the chair. At the end of the treatment (shoe shine), the customer will pay the operator who did the shoe shine for him. We will ask the operator to key in in the store system the transaction and issue a ticket At the end of the day, to cross check that the operator did not do any treatment without declaring it (ie stealing), we will cross check number of transactions entered in the store system (that issued at ticket), the number of times the seat has detected we had a customer for treatment, and the number of customers detected via the camera. We are looking at an electronic application that can 1) Count the number of customers who spent more than 5min on a seat 2) Detect from the camera images the number of customers who had the service during the day 3) Notify the store owner if any discrep...

I need developed complete electronics (populated PCB) as described here:   [obscured]  /controller/ Long term production will be required and I will need a cost per unit/ in volume of 5-10 units but production is NOT a part of this platform. Just the development which includes the design and working test unit. I'll need all paperwork associated with the design. Each time we re-designed we improved the end product substantially. That is why I am making this query. This will be our last improvement (I said that before) so it needs to be done correctly. Note: I have several versions in the worldwide market since 2008 so I know EXACTLY what my costs are. Any/all bullshit will be ignored. I wasn't born last night.

Most of the time I have 120VAC available via generators. However, when the generators (which is the prime power source) run out of diesel I need at least an hour or two to continue powering my sensors and cell modem. They both require 12VDC and at full draw require 350ma. This is the peak when the cell modem is transmitting. While not transmitting the requirement is less than 100ma. So I need batter backup. Solar is another option as more and more I am going to places where the generators are only used at night (light towers). I may have to get more use out of this option at some point. Here are the general specifications: - 120VAC input - Battery backup (4x AA or equivalent) - Solar backup (12v 10W panel) - 12-15V DC output for sensors, cell modem, and 5VDC regulator - a voltage meter scaled 0-5V from 10-18V for the MCU ADC - digital output for detection of battery (HIGH on AC, LOW on Battery Backup). Please send me a quote on this project for a Schematic, BOM and general board l...

Atmel IDE Design Platform ARM Cortex Processor Processor: ATSAMD20J18A This is a two part device where the devices control and communicate with each other over a bluetooth interface. Person should be familiar with: Embedded microcontroller coding, C, C++ Embedded System Development Basic Understanding of Electronics (No hardware design required.) Atmel Studio IDE Atmel ASF Controlling a Bluetooth Interface (HC-05) by a UART port with AT commands. Controlling remote devices on PCB through an I2C interface. Some capability speaking and writing English to document and comment code. Comment: Do not need HW design skills. That is nice to have but not necessary. I am an EE with a lot of design experience. PCB's have been finalized and are now in board layout, so the intention here is to get started on the code while the boards are getting laid out and fabricated. More details on the project will be given to people so a better time and cost estimate can be made. Prototype versions...
