I need a pcb made for this schematic. Its to convert arcade machines that dispense tickets into machines that dispense coins using a hopper. The company that used to make them went out of business. Only accept if you can make a copy please
Atmega based ride height controller for a vehicle. I have a schematic, but need to redo it due to parts being EOL and cost reduction. Current design is 2 boards, I'm hoping to get it on 1. Hardware only no software, I do that. The main board has fixed size, mounting and positions per the attachments Keith Vasilakes
I will povide the schematic diagram , its an urgenty short project
Hello! I am currently working on a project for a device that needs a type of control panel to use to execute commands. This is similar to a HMI PLC all in one device but I don’t think I need something that advanced. Please see attached document for full details I look forward to working with you!
Looking for an electronic design engineer who can take our solenoid testing circuit, final design right up Gerber files&Bom stage and create firmware. And the engineer will be contracted to guide us through the prototypes for us
Design a AC based on yeti type cooler with water pump, transmission cooler, fan and ducts.. Example link bellow.. Need more compact (hence yeti type ) and be able to last 3-4 hours with ice... Looking at a 35 qt cooler
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.

I have a PCB that is doublesided and i want that PCB in KiCad 6 The Job is to redraw the complete PCB in Kicad (without Schematics). So that it is possible to create Gerberfiles from there, to reproduce this PCB. For all Parts should be used Footprints and not only pads. Basic Projekt Setup is already there. Quality of the Pictures of both Sides of the PCB you can see in the Attachment. Size of the PCB is 150x120mm
Need someone to guide, consult, review and correct our product for production.
details will be trough the chat pls bid and i'll get back to u thanks
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, i need help to build a bartender with a nema17 stepper motor and a Linear guide and 1 servo. i already have a idea of how it should work . i need help to chose the correct components (stepper driver, Arduino or Raspberry pi ect...) you will have to help me choose the right components and help me write the code for the project to move forward. i already have: - arduino uno - raspberry pi 3/4 - linear guide - stepper motor - drivers (TMC2208,DRV8825) I have a preference for the raspberry pi and python Maybe only weekend we will be working on this projet, i'm not in a hurry, the goal is to learn at the same time I speak french and english if you have any questions, do not hesitate to ask questions in private in order to fully understand my needs
Hello developers Request details We have developed an AC charger based on OpenEVSE. We would like to add ISO 15118 (specifically plug'n'charge and SoC reading) to the existing board. Will discuss more details in chat.
