We are working on a medical related device. The core device work is done and has been validated. It operates on a PIC processor and integrates via USB with prototype software on a PC. We need to embed this prototype software into the system and add a touch screen, RFID reader, PDF report generations and additional storage memory (for reports). We are still trying to figure out the best architecture for this. There are several options. 1. Expand the existing circuit and upgrade the processor to handle all task. 2. Embed the existing device as is into a new device with a new processor and additional circuitry for touch screen, memory and RFID. The two devices would talk via RS232 or other. The new firmware replicate the prototype software features and functions. 3. Embed the existing device into an off the shelf Linux (or other) based system. Write software for the new device with the user forms and test flow, PDF features, etc. We are looking to balance development...

We have a unit that does an RS485 handshake with another unit. it's very basic and only has to control 6 LED's and instruct the unit that it is connected. We need to understand the RS485 data and create a raspberry pi interface so the the unit handshakes with the raspberry pi and not the other unit. We have test equipment so we can provide you with information as you need it. Once we know what the code is and how to communicate with it, we can build our own PCB that will input to a raspberry pi GPIO rather than LED's. There are 3 further projects once this one is complete. We're keen to find the correct developer for all the elements in the project.

Having to re-post this job as upwork were unhappy about the links to the components we need to use. We're testing a vending machine and need to monitor the pressure switches (these are just simple switches, 4 of them). These triggers would simply be high/low inputs on the GPIO's. We'd like to use a raspberry pi to take the triggers (as they occur) and then send the info via SMS with the Pi's MAC ID. This will allow us to see if the machine has overpressured. We already have the 3G routers so just need the raspberry pi code to monitor the pressure switches and send SMS or email when they're triggered. we've used temboo for this in the past and it's pretty good. If this project goes well, I have at least 3 other projects that will be much more challenging and with bigger budgets. This is a guaranteed project for the right applicant. ADDITIONAL NOTE Hi everyone, Some more info that may help you. We'll be using a proroute H685 3g router. it connects to the ethernet...

This is to design a medical equipment to test blood sample. It consists of 4 parts. 1. Sample Handling and Preparations It draws blood sample from tube, deposit aliquots to 3 mix cups, and mix with reagents. The mixtures will be used for further tests. The transfer of samples is by vacuum and pressure, and controlled by Solenoid valves. 24 solenoid valves are involved in the transfer of samples. Their operations are controlled by the system. The amount of sample is accurately controlled by a device that is operated by stepper motor. 2. Light Absorption Measurement One aliquot of the sample from step1 is transferred to a light absorption device. The light intensity after the LED light passes through the sample will be compared with a reference light. The difference will be compared. The result will be read. 3. Optical Flow Test One aliquot of sample from step 1 will be inject to a flow test devices by a syringe. The syringe is controlled by stepper motor. The Laser light is applied...

Hi, We have source code for our Android system. We want to customize this ROM, things like: - Change Default Apps - Add root services - Customize Skin - Customize Splash & Bootloader screen and so on. Need consulting on the above first, And then the entire project. Apply only if you've worked with customizing Android ROMs before. Thanks, Ashish

I need to get setup CoovaChilli on my router (TP-Link WR740N ) running OpenWRT Barrier Breaker 14.07. I have my own RADIUS server (daloRADIOUS on Cent OS) to manage HotSpot Login and Accounting. I just need to run the Coovachillin on my router. Rest I will do myself. I will provide remote access to my Router over Team Viewer.

We are in need of someone familiar with creating virtual appliances on Linux. We have an application comprising a JVM based backend and an AngularJS frontend. We need someone to take these two components and produce a Linux Appliance that we can distribute as an OVA.
