Electronics jobs

Necesito una persona para diseñar varios circuitos que tengo en mente de electrónica para un escape room. Busco persona seria, rápida, fiable y económica. Los mecanismos no los puedo decir por aquí por la confidencialidad. Pero básicamente acciones activan reles. Como la luz, el ruido, cosas de este tipo. Algunos un poco mas complejos, etc. Mejor hablarlo...

Hello, i would like an inverter circuit,diagram, with a mppt charge controller inbuilt and running on an Atmega328 michrochip. Components should stricttly be through hole.

Hi liznyambura, I noticed your profile and would like to offer you my project. We can discuss any details over chat.

I need to develop an infrared laser 'shield' to detect high velocity projectiles traveling through. The laser 'shield' will be mounted in front of a cardboard target, and will have to give an responsive feedback to the user-system of where the hit occurred. To ensure precision, the laser shield have to respond up to 150 000 times pr. second - as the fastest moving projectiles u...

i need someone who can develop software for a gps tracker. an arduino nano 3.0, adafruit ultimate gps breakout 3.0 and a mini sim800l are the components being used.

Hi, i need someone who understands a bit more about Sniffing GSM using RTL-SDR USB would like to know what kind of gsm/rf frequencies are around me. Spectrum analyzer software could be used. I have bought the hardware 100 kHz 1.7 GHz Full Band UV HF RTL SDR USB Tuner Receiver R 820 T 8232. Read Less

Designing a low-frequency filter with the following characteristics. Supply is +5V and GND. The filter should have a gain of -10 (inverting). (Gain in this context might sometimes be referred to as AC-gain) The filter should have a bandwidth of 1kHz. The filter should be able to drive a 100 Ohm resistor. You should make a design with an opamp (try and select one) and back your findings wit...

Hi there, I would like to control 5 stepper motors with an arduino to work in a specific sequence. I have no experience, and have never coded, but have a fun little project to do and have been told that it is an easy job for someone who knows what they are doing. The motors and drivers I have can be found in the below link. I do not know if the code or information they give in the link is comp...

A small form factor PCB with simple components

Pretty simple. Need a website built for an automotive repair shop. Would like it to have an embedded blog. I know enough about php and html to edit the site which is what I want to do as I expect to make changes.

I need some help related to an electronics research project with the topic - Accident Identification and Alerting Project

I work at a crash test facility and we use a lot of piezoresistive accelerometers. That being said, we need to be able to quickly check the functionality of the accelerometers before we put them in a car for a test. So I need someone to build a handheld device that can measure and tell me the resistance on both sides of the wheatstone bridge inside of the accelerometer.

need an expert on c to write a code

Hi, I have a hotel project with Bosh FPA 5000. I have experience with fire-alarm systems but I never used Bosh. I need someone to teach me those systems.

We find an electronic expert designer to customize an hardware based on VIDEO Sitara Processor TI AM5728. All documentations are provided by Texas Instruments (Gerbers + BOM + all required ). We want to 'add' to the basic Ti HW some input/output : HDMI, HD-SDI, Audio, SATA port, ... I send more detail on demand.

We are looking for someone to build Hardware on very thin foil sheet which can can Read and Store EMV Chip Card Data. Please only bid if you are capable of doing it and have all the things needed or can arrange to do so. Rest of the Project Details will be provided upon contact.. Plz check Attachment for little details

I want a software, with which I can turn on/off my office lights, airconditioners, and other machines. for this purpose I need automation using arduino board with electrical wiring etc and other stuff needed for that.

Create from zero a GSM data receiver able to capture wireless info sent via network i need a GSM Reciever/Sniffer built or someone who has one please contact me for more details. the individual i assume will need to have experience in electronics and some coding.

actually tell me how to fix the 4 door lock with 4 led using 1 adapter currently now i using the series circuit for relay but how to change to parallel circuit pm to find out more because currently i found that may not be the software problem as i able to power up 1 adapter with 1 lock and led but when combine 4 lock with 4 led then the lock not enough current to draw, but how to do in parallel?

I require a small circuit design for 905nm AD500-9 TO52S1F2 APD/Avalanche Photo Diode with 905nm Bandpass Filter Lens. Please see attached files for High Level Overview and APD notes. This circuit is only to detect/receive and thus amplify 905nm pulses of light from the APD and output via the OpAmp suitable for Arduino to recognise on its input pins. The circuit shall provide the power requ...
