- PCB review for suitability of components that are no longer available on the market. - Add temperature sensor on PCB - Ultimate goal is to make the PCB with the lowest possible cost of production and manufacture 10 samples for test.
I am copying a PCB (without Schematic), I have made the PCB, but I am stuck with changing the parameters of all the parts, I want JLCPCB to do the SMT, and they need complete BOM and the part numbers must be added, so can you help me with that.
I have a gaming mouse which I would like to have the mouse switches replaced. I required some desoldering and soldering experience which I have none. I will supply the switches but I just need someone to do the actual job of switching them out for me. I am looking for someone in the Boston Massachusetts area.
All these devices are 1S to 8S for RC models, I need the gerber and BOM to make the same simple device for Li ion 12S battery nominal 48v being used for solar storage as a cheap alternative to BMS , should be a breeze for an electronics wizard , thanks
Good morning, I have made a project with a pcb composed of a nodemcu V2, a resistor, a 5v power input and a connection to ds18b20. I would like to have that project with material that does not need soldering.....

The Sketch needs to scan for specific BLE devices and then display a signal strength via a coloured 5 led bargraph, play a beep, and show accumulated points for the time spend within the vicinity of a found BLE device. Required deliverable for this project will be a single Arduino Sketch. This project is a follow on to a previously completed Bluetooth BLE Scanner MIT Inventor App (see project brief attached). The APK can be found in the project files on Freelancer. The objective of the MIT Inventor app was to prove that the BLE scanner concept would work. This follow-on project will to be to extend the concept to an Arduino Nano Microcontroller. See attached PDF for full project description

Hello, I'm interested in building a small controller for my small garden room, that have input, and then based on input data, it deals with output. The following are the main input and output. - Battery level reader - 2 Water Pump for 2 different job work - Water level - small Peristaltic pump - Humidity reader - Temp. Reader. - Open switch (to let fan work and decrease humidity) - Open switch (to let EVAPORATIVE COOLER work) can it be done with Arduino or another microcontroller that work with battery? if yes, then how ,much will this project cost me? (I already have the programing code)

Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.
Requiring a quote/pricing for a project that involves ADS1299, Micro SD Slot, ESP32-WROOM-32D, USB and some programmable LED al being on one board and controlled by the STM32 controller. Your task would be to make all components to communicate with the STM32 and to be able to extract data from the ADS1299 using USB to PC, Bluetooth to PC and Android device . For PC and Android device to have an App that will represent graphical the extracted data from ADS1299. Pricing can be negotiated.
We are looking automatic wire cutting and stripping machine which can do this job from 0.1 mm wire ( copper wire) upto 6 mm sq and of different lengths. The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.
I am looking for someone to design an PCB for electronic device which emits a sound when acceleration exceeds a certain threshold (0,5g).

This project is to adapt an MPLAB project from a PIC32MX795F512 to a PIC32MX675F512. The previous project was completed on the Microchip Ethernet Starter Kit II and is an Ethernet 2 Serial project. There has been a new pcb built with the 675 but with many of the same components as found on the Starter Kit. The new board has some pin changes from the Starter Kit. As much as possible has been kept the same. The new board does have more capabilities than the old Starter Kit. The new capabilities will need to be implemented as a separate project after the basics have been achieved with this project. A document outlining my general communications policy and another document showing the pin changes will be included in this project. Please communicate any difficulties you may have wit...

This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects
Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.
Hi, i need a same day turnaround for a program for a linear actuator contoller using esp32-wroom32D. I have a custom pcb with the esp, relays, power, eol sensors and led/sounder output, and would like it coding so that a bluetooth remote (used for a phone camera shutter) can trigger the actuator to extend or retract. I have been let down by my engineer and need to get this running today. Thanks!
I am designing a connector board. Looking for schematic capture engineer for the same. It takes hardly 2 hours.
I like to setup door open / close monitoring with ESP32
Complete code with simulation of drone in any online platform. Quadcopter at simplest with all control simulation.
first the ultrasonic will detect the water level, if satisfied then start an internal timer and turn on the second relay for 5 minutes. Next, the proximity sensor will detect the distance of the fluid and control the third relay. Lastly, a tds sensor will tell whether to open the fourth relay or open the first relay whereby activate the ultrasonic sensor again
I want to read clean audio signal from a i2s microphone. I should be able to set the select or reject desired frequeency range. The output should be routed to the audio jack. Also it should be routed via bluetooth via A2DP profile. The hardware platform ESP-A2S , ESP-ADF, and so on.

I am looking for an AVR/ESP programmer who will help on the code to generate an 8 pulses signal at various frequencies and various duty cycles using ESP 32 and ATMEGA328P based arduino NANO. The frequency varies from 200Khz to 1Mhz. (There is a table for the various signal pulses on the PDF files). The 8 pulses are to drive a PNP transistor! An image of a pulse we are looking to achieve. The signal in Yellow is the result we are looking for. I have other tasks as well!! Can you do it?
Hi there, We manufacture a product that uses a PIC32 as its main processor. We have connected a USB socket to the correct dedicated pins on the PIC32 (D- P56 & D+ P57) and wish to be able to have end users update the program inside the PIC32 using either a USB stick OR using a cable connected to a PC running a small uploading program. (Our testing proves a PC connects to the PI32 when the USB is plugged into this socket - the usual Microsoft chime alerts us to the connection). Will discuss more with good developers. Thanks
