I need to design a LED chaser that will be powered by a 12V battery. It needs to have a master PCB which will control all the slaves connected. The slaves will be chained together and distanced about 5 meters apart with a 4-pin connector IN and 4-pin connector OUT. Each slave will have a 12V lamp attached and switched by a mosfet. The requirement
I want to take my arduino mega project to a prototype stage. The project uses these external modules: arduino mega 2560, 4 buttons (interrupt pins), ds3231 real time clock, 5 port 220v relay module, 4 RGB LED, 5110 lcd screen module. The circuit receives 12v 3A input. I would like there to be 5V and 3.3V management for the modules as required and one 24V on the 1s port of the relay. The extern...
We have a very specific design we wish to enhance that requires the cirrus metering chip. We want someone to assist with design of the schematic, BOM and PCB design. Experience with metering chip preffered but you MUST be able to speak and meet deadlines.

I need some help with selling something. Iam the manufacturer of organic waste converter of super...biogas plants and having a dealership of STP plants,I need people who market these products on percentage basis as usually these products are mandatory for clearance of BWSSB,PCB,BBMP at apartments and IT parks etc places where waste is generated more.
The goal of the project is to transmit live data from an Adafruit LSM9DS0 Accel/Gyr/Mag v1.0 via the Adafruit Flora controller over the Adafruit BlueFruit LE module. This data will be deposited in real time into a Google Sheet via Temboo or another process for future visualization and analysis. We have experimented with a wifi enabled Arduino Uno (using Dragino Yun Shield for wifi) and we are ...
PCB layout using Allegro/Orcad version 17.2 (Don't use 16.6) 1) Update schematic, minor changes, may include creating three footprints 2) Understand and follow the specified component placement 3) PCB layout with necessary consultation 4) Prepare design files, ready to order PCBs
...MEMS sensors feeding an analog processing chip, to an ADC to a PIC micro. we built 3 PCBs for prototype test. the first was populated and had a short. then we tested the bare PCB and there is a short that we simply cannot find. At this point, all I am looking for is help finding the short before building more. Could be a manufacturing problem, just not
Hi Walid, I want to design and build a pcb here in Egypt and looking for a freelancer located in Egypt in order to deliver me the final PCB. I want to build a PCB with 5 shift registers that can control 20 relays and accept 20 buttons as inputs ( total 40 pin ) to be controlled by ESP8266. It is fairly simple board but I need it as quick and clean
