I am designing a system to detect a baby cries with a microcontroller, Arduino Mega. I need someone to design a circuit or guide me what kind of sensors is able to detect baby cries. I have bought a SparkFun sound detector but it seems that it doesn't sense the cries.
wireless Power transmitter &Receiver Specs Input - 12v Output - 5v / 3A Tx rx coil distance - 5mm Tx rx coil diameter - 100mm Circuit cost should be minimum
Hi All, I'm looking to work with someone to design a PCB board for a GPS Module and suggest potential components. The module will be battery powered ( Not LiPo), need to have low power consumption, be able to run some code (max memory approx 20,000 bytes). It will work with a Tri-Band LTE-FDD and Dual-Band GPRS/EDGE module solution, most likely the 7000 series. The outcome for this proje...

I have a very simple Cadence schematic and layout I have designed of an XOR gate. For some reason the nest lists do not match in the LVS check. I cannot figure out this simple task because I am new to the process. The layout cannot change but corrections can be applied and the entire schematic can change to make the proper corrections to match the layout.
I'm looking for someone to develop the circuit with a Hall Effect sensor (something like that) with Wi-Fi. This design will be used to check if the door of a safe is closed / open. Basically the circuit will be off to save battery, as soon as the state is changed, the circuit will be turned on. I intend to program the device, I have preference in ESP for Wifi connection, but I am open to sugg...
as per the attached schematic i am looking for someone to have this made then mailed to me. two blocks of rj45 connectionson either side of the board, one connection with relays on certain pins triggered by a 5v GPIO signal. further details available. I would need someone to make the PCB layout, have two units made, and then mail them to me in Canada. I look forward to hearing from you. Th...

i. Investigate characteristics of separately excited DC motor over its normal operation range ii. Investigate the effects of varying the armature voltage iii. Investigate the effects of reducing the field current Further details will be shared while screening
I am searching for an electronic hardware engineer who can work together with my team in The Netherlands and China for the schematic design and PCB layouts in Eagle.
I am looking for an engineer who would be able to document for the serial communication protocol employed by TB50 batteries. These batteries communicate presumably by SBUS with a host, it seems the batteries require a message in order to activate their output and then they pass out various data on the cell voltages, temperatures, cycles, etc. I need a packet structure inxluding any headers require...
The objective is to design and build a housing for a piece of electronics that will be attached to the ear of a cow. The housing must hold the electronics in place and protect them from hits and water. The housing must also allow for an easy replacement of the electronics within it when needed. Creative ideas are very welcome. The main criteria for accepting the designs are visual appearance and p...
I want a project partner who can work with me on "Testing of reversible circuits". The clients bidding must have knowledge of algorithms, python and testing methods of reversible circuits. This is a very serious and big project. Before hiring, I would test the client by asking him/her to write a small algorithm and a code. If satisfied and found optimal, you will be hired.
Would need the idea to be restricted for now, however we are looking to build our differentiation over and above a camera like Mi Home Cam ([login to view URL]), for a reference. Hence need the right team member who can take up the task for PCB design & firmware programming for this project.
I need help to design a small portable charger with two PCB's, one for USB, one for wireless headphones. Need help to make sure unit doesn't overheat as it will be quite compact. Have attached rough drawing below. Any questions, please ask. Patrick
I have one nRF24L01 on the Raspberry Pi, and let me define this nRF24L01 as “Master”. The Master will send a signal every 1 or 2 seconds to many “Slaves” device. Initially the Master is at talking mode, after sending the signal out, the device will change to listening mode and wait for ~0.2s to receive the signals from all Slaves. The Master uses one talking pipe to talk to...
i need 2 project of electronics btech with the soft copy. it is urgent . if any one already have projects can bid only

A microcontroller with weight sensor to measure a weight setpoint. If object is heavier than setpoint, a signal will send out to turn off the switch and motor will stop . There must be a casing with digital indicator to show the weight. The project ideally should be made in Singapore .
I AM LOOKING FOR SOMEONE TO TUTOR ME A SUBJECT I NEED HELP WITH I HAVE THIS SEMESTER, ITS CALLED "SENSORS AND MEASUREMENTS". ITS USUALLY SENSORS AND CIRCUITS AND ETC. LOOKING FOR SOMEONE WHO IS AN ELECTRICAL ENGINEERING GRADUATE SO ITS BETTER IF HE TOOK THE SUBJECT. ASAP
Need a programmer to create an Arduino library for interfacing with the MCDC04 chip. All I2C functionalities of the device should be implemented as defined in section 6 of the datasheet, and formatted into functions in such a way that makes the library relatively easy and straight forward to use. (Similar to how Adafruit or Sparkfun writes their libraries.) Commented code is expected, however it ...
hallo, i am looking for a transverter that could shift the whole LTE band 20 to wifi 5.8Ghz band
I need to control 4 solenoid in a certain pattern. Parts need to be used for this project is OP AMP as an Buffer, opto isolator, 4 channel mosfet board, NI DAQ 6341. Attached please find the previous schematics which my team lead has shared with me. he asked to com up with some ideas or design the circuit because it has some flaws in it. The op amp will burn out for some reason, the input signals...
I am looking for an expert Electronics engineer to do the electronics part of the coffee machine. We are making a new coffee machine. Herefore the internal electronica has to be developed to the stage that it works with the housing we have.

I am an electronic and communication engineer. i want to develop a digital jacket which will be control the temperature of the human body. it will contain sensors and a micro controller which will communicate an bring a relief results.
I'm looking for a developer who will write a Arduino/raspberry pi software and compose set of equipment. Arduino / Raspberry Display - alfanumeric Barcode scanner Relay Purpose That is a tool to match if barcodes from 2 boxes are the same and matches together. User scans 1st box, code is stored, user scans 2nd box -> if barcode is correct, signal is sent to Analog output for Next XX...
This is a small project, i am looking a quick resolution, you have to just use the Arduino debouce lib to connect 4 pins ( push buttons ) to the other 4 pins ( relay ) on a esp8266 microcontroller. i will share a quick demo as well. The push button should work even while the microcontroller is not connected to the internet. Protocol used ( MQTT )

Need to trigger sounds using a dfmini player module in relation to a LDR sensor for a project I'm working on within a toy company. Would be good to get some advice for future projects also by talking me through your process
The circuit is inside of an electrical plug supplying power to a battery charger. I need someone with the right equipment to record the communications between this circuit and the charger. I will provide you with the battery charger and the plug, with the cable spliced to enable tapping into the signal wires. The communications occur upon plugging in the cord, and periodically thereafter. I think ...
I need some expert in electrical engineering. This is course of it.
I have a image file of circuit. i want to make the Eagle sch and BOM. I attached the image file. your task is to draw sch on eagle and make BOM I recommend the digikey and mosuer for BOM. I hope your good response. Thank you.
