We need a small PCB that has a Lithium ion battery Charge circuit that charges a 3.7 volt 180mah battery and also an RF 415 Mhz receiver circuit on one PCB. I would like the PCB to be 30 x 20 mm maximum in size. Is this possible? The board would need a micro USB port and on/off button on board.
...tremolo distortion circuit (pic code all done, just need board layout which is part done, and a good layout to eliminate clock noise) -simple octave up and reverb circuit (layout done, but signal does not pass as should) - a simple two stage distortion circuit (layout done but gain is too large between stages) -a simple reverb circuit (layout done, not
...code to be deployed from windows based computer to future prototypes. Code will need to be adjustable for future changes of inputs/outputs. The project is to use an Arduino circuit board You need to write a program for the Arduino to receive signals from the ultrasound that will tell the Arduino board to display in mL the flow of liquid then after max
...foot-print PCB board for wireless module. PCB board contains USB, MCU, wireless chipset (IoT wireless chipset), antenna, and a number of connectors. Must have experience with antenna, RF, and USB impedance control, ground isolation and layers, and USIM and other connectors. CAD tool is EAGLE or Altium. All necessary files for PCB board manufacturing are to be

I need you to provide solutions to some electrical circuit problems. These include mesh analysis, op amps, thevenin equivalent, power dissipation etc.. Let me know if you can do it.. details will be provided via chat...
I would like a circuit design and product recommendations for my arduino project. The circuit should be arduino controlled and based, some components I have selected, some I would like recommendations for. I would be happy with selection of parts from here if enough choice is available to make sensible selections based on the requirements. https://www
Current project is building a digital swing weight scale for golf clubs. Digital scale portion is built using an Arduino Nano, 1kg load cell, HX711 load cell amplifier, a pushbutton, and a 1602 I2C LCD. Attached is the code which works fine and a pic of readout I’m getting on LCD. All good. What I would like to do is convert the gram weight to swing
...for a portable heater that contains two materials ceramica where the nicromw coil will be, and plastic for the main body, the prodcuts must have full and easy access to the circuit board, LED lights for the looks, i will provide picturs of the battery that will be used to power the nicrom wire. I will be useing 3d printer to print the plastic main body
...produce other electrical documentation such as GA drawings, termination drawings, cable schedules, etc for automation control panels. Your challenge is to produce: - Functional circuit designs from the list of components, as your circuits will be used to build control panels. - Polished and professional documentation which will be provided to the end customer
This graphviz diagram contains all the nodes and edges I want but formatting needs to occur so it looks better and communicates more effectively. For this project, adjust the *.dot file to make the diagram look better. I've included the .dot file as well as a png of the output.
Designing and Developing the PCB for Battery operated and Bluetooth connected Drums Sticks, which when connected to Smartphone, creates music on the Mobile Music App. Drumsticks replace your figure from the Music App and create music when played on any surface.
I have tried several times but I may not be getting it right. I am looking for the ability to create an Arduino controlled garage door remote RF reader for my home automation system. A separate Arduino will be able to send the same door code. This contract will require providing a working copy, a parts list as well as the Arduino code.
