Digital Solar Corp. has developed a heating system with inter-seasonal storage to heat most on-grade buildings. This is a leading edge sustainable, carbon free project. We are now just starting out in the Solar Thermal Chiller arena and are extremely budget conscious. We require a fluently English speaking programmer to build a Python application to operate our existing controller. We presently have a python heating application for the Pi already and it uses the same controller, sadly our existing programmer has simply fallen off the face of the earth of late and we have heard nothing from him. We are unable to wait any longer thus we do require some dedication to complete the project in as short a time as possible. The expectation is the program will be designed using Classes and Multi-streaming, plus optimizing the Pi core operations. A database is required to store data, concatenated over time and a graph similar to the existing heating program showing averages and peaks over time. An NDA is required to be signed. This may lead to other work if satisfactory. This offer is only open for 5 days and closes midnight June 9, MDT *In a separate requirement*: We will also shortly require someone who can troubleshoot our existing controller design. We will be putting this on Freelancer as well shortly. We have a PCB including all the files, schematics, Gerber files, etc., and require someone to troubleshoot it, adapt it, and test it to completion. Other then the Relay control points, this is a low voltage application, 24VDC supplied. One version already functions, our new integrated board requires attention. They are supposed to be identical in operation. The Pi controls the board(s) by way of its I/O. If interested in doing both please advise. There is no requirements in this offering to do both.

Thank you for looking at our bid. Sorry for quoting way above max budget/timeline. We do not have Pi of the required spec, we can buy one get an opportunity. Maybe you existing controller can be a good starting point, or something based on Tornado - request your response to discuss. Kindly check out my Freelancer portfolio https://freelancer.com/u/fleetways.html for previous work. It would be great if we can get an opportunity to discuss this project further.

Dear Sir, We have couple of queries regarding this project: 1. We see three program modules in this project, one is for hardware controlling second one is for user access and a web server. Is that correct? 2. The second and third program modules almost look similar. What features exactly differentiate theem one from the other? 3. The landing page is the web server page that is supposed to be displayed when a user visits a particular mode. Is that correct? 4. Try explaining the expected working of the system with an example of one complete cycle of the system. 5. Define the thresholds for temperature and other parameters and define the events you wish to trigger when the particular threshold is hit. A long time ago we worked on a similar project like this which was designed for an agricultural system, which lets you control your irrigation systems, fertilization systems from anywhere in the world. Moreover, you can schedule these processes with a pre-scheduler on a daily, weekly, monthly basis as well. Following are the deliverables that We can provide you with: 1. PDF: Schematics, PCB Artwork, 3D view of PCB 2. Source files: Schematics and PCB file in Altium 3. 3D step file of the PCB 4. Gerbers 5. NC drill files 6. BOM 7. Firmware/Software/Codes/Sketches 8. Prototypes and mass production. Thanks and regards, Prashant
