Looking for someone who is capable of creating a layout and fabricating a PCB equipped with a microcontroller, bluetooth or wifi and two electrodes that will measure the conductivity of a liquid solution that comes into contact with them. This board would have to be optimized to as small a size as possible. That measured conductivity data would have to be able to be wirelessly transmitted via bluetooth or wifi to a smart device (laptop, phone). An app would also be developed later on to display conductivity data.

Cool Startup needs some advice from an electrical engineer. We need a small (micro) power converter that can go inside a custom electronic case we are making (apx. measurements of the case are: 6” x 6” x 2”, this will be filled with other electronic parts as well fyi) This power converter will need to convert 110V into two separate power channels. 1. One will connect to 12V electronic door solenoid (just need two wires for the relay) 2. Second will connect to 5V micro usb port for Raspberry Pi 3 (need actual micro usb connector) with the highest Amp as possible because we’re going to power LED strip out of Raspberry which will use A that’s left after raspberry takes it’s part. Good reference for a raspberry power supply is this 5V 2.5A power adapter: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/ref=pd_sim_147_1 Relay we’re going to use to trigger solenoid is this: https://www.amazon.com/uxcell®-2-Ch-Relay-Module-Optocoupler/dp/B00S4VQA1A/ref=sr_1_1? If you are can help find this answer, you will be contributing to a super cool project Shane

Hello, I need someone with experience in doing electrical calculations and drafting for houses and villas. The architectural part of the project is almost complete, and lighting has been designed as well. I need someone who will draft the full electrical package including smart house features we will agree upon later on. Attached is a floor plan for your reference. The house is a bigger one but fairly simple. Looking forward to your applications, Aldin

We need to [develop / improve / finish] an Android app that interacts with Bluetooth devices. The device is a portable datalogger. Currently we have a semi-working app that is able to interact with one Bluetooth device. We need to finish working out the bugs and expand this functionality to make the app download from up to 6 devices in close proximity (i.e. connect and download from 1 device, when finished, start downloading from device #2 automatically, then #3 and so on). Each device can have approximately 150k data points. Current app version include this features: User selects the desired device Connect with a single Bluetooth device Get the device status (ie bat level, sampling in progress, etc) Start / stop sampling process (sample means enable device to store sensor data to internal memory) Download acquired data and clear memory Show XY chart of the data and export to CSV file We need to break the work into 3 milestones: Milestone 1: Finish fixing bugs when working with 1 device (mostly cosmetic, random crashes when working across new/old androids) Milestone 2: Multi device implementation. We need an app to work with multiple sensor same way it works with a single sensor. That means, user would be able to select up to 6 sensors on the screen. Then, if the user taps “Start sampling”, app should connect with each device and send a “start” command one by one. Same for stop, download, memory status etc. Milestone 3: Improved user interface (TBD)
